New description: [New technical field] • This creation is a kind of compound type 赖 throttle n, the scale can dynamically adjust the flow pressure by elastic film according to the load end pressure, and then accurately feedback appropriate Fluid pressure composite film restrictor. [Prior Art] In the early days, the most common flow regulating devices included the types of "fixed Lu flow resistance" throttle valves and "variable flow resistance" throttle valves. The principle of the "fixed flow resistance" throttle valve is to create a throttling effect when the working fluid passes through a fixed orifice. When the working fluid pressure of the r fixed-flow type "throttle valve" increases, the flow resistance also increases relatively, which will result in the inability to timely provide the pressure compensation of the load end. With the advancement of technology, a "variable flow resistance" throttle valve with spontaneous pressure feedback function was developed in the later stage. This type of throttle has a flow control device with a spontaneous pressure feedback function. In addition, it has an automatic detection, timely compensation of the pressure and flow in the fluid system, and the function of the pressure anti-lock adjustment device. The load system that is connected in series with the working fluid supply system achieves pressure compensation performance. As for the operation principle of the pressure feedback restrictor, a mechanism having a flexible or displaceable characteristic such as a piece, a slide shaft or a slider is mainly used as a main feedback mechanism. The above-mentioned feedback mechanism will also change the degree of pressure drop inside the adjusting device while generating the deflection or the time and the flow pressure and flow rate at the output end of the fluid supply system. When the force feedback adjustment device successfully starts the anti-town mechanism, in addition to the second sense M369483

It is a defect in the technique that is prone to wear, blockage, and delayed reaction. In this way, the composite film restrictor of the present invention can have the characteristics of spontaneous dynamic pressure, fast feeding, fast response and precise flow control, and has the advantages of simple component assembly, convenient assembly, and low production cost. [New content] The present application discloses a composite film restrictor for throttling a working flow in which the working fluid can be a liquid, a gas or a supercritical fluid. The composite film restrictor includes a housing, a body, a throttle member, an elastic film, and a fine adjustment screw. The housing has a source end, a load end, and a first receiving space connecting the source end and the load end. The body is disposed in the first accommodating space, and the body has a second accommodating space, a third accommodating space connecting the second accommodating space, and a first draining channel connecting the second accommodating space. The inner wall of the body at the second accommodating space forms an internal thread for guiding the fine adjustment screw. In addition, the housing and the body form a second drainage channel, and the second drainage channel communicates with the source end and the load end. The working fluid, the second split, flows from the source end into the second drain and flows along the second drain to the load. The M369483 throttle member is disposed in the third accommodating space, and further includes a throttle ring and a throttle table. The throttle ring has a fourth accommodating space. The throttle block is disposed in the fourth accommodating space and forms a tempering chamber with the body, a regulating chamber connected to the tempering chamber, and an inner hole connecting the load end of the regulating chamber. The elastic film is disposed between the adjustment chamber and the pressure stabilizing chamber and forms a gap with the throttle member. The fine adjustment screw is disposed in the second accommodating space 'having a projection extending toward the third accommodating space' for abutting against the elastic film, thereby adjusting the gap, wherein the fine adjustment screw may be a single screw. The diverging system of the working fluid flows into the conditioning chamber from the first drainage channel, and sequentially flows to the load end through the gap and the inner hole. When the flow pressure of the working fluid at the load end is increased, the elastic film is pressed by the working fluid to increase the gap', thereby making the fluid resistance of the first splitter smaller, thereby adjusting the flow pressure of the compensating load end. Compared with the prior art, the composite film restrictor of the present invention utilizes the deformation of the elastic film to dynamically control the pressure difference of the working fluid between the source end and the load end and timely feedback the pressure change of the stable load end to solve the problem. The phenomenon of easy wear, blockage and delayed reaction in the prior art. In this way, the composite film restrictor of the present invention can have the characteristics of spontaneous dynamic pressure feedback, fast response and precise flow control, and has the advantages of simple components and convenient assembly, and low production cost. The advantages and spirit of this creation can be further understood by the following details of the creation and the drawings. [Embodiment] 6 M369483 Please refer to Figure 1, Figure 2, Figure 3A and Figure 3B. Figure 1 is an exploded view of a composite film restrictor 3 of one preferred embodiment of the present invention. Fig. 2 is a cross-sectional view showing the composite film restrictor 3 of Fig. 1 before assembly. Figure 3A is a cross-sectional view showing the split of the composite film restrictor 3 of Figure 2; Figure 3B is a partial enlarged view of the composite film restrictor 3 of Figure 3A. As shown in Fig. 1, Fig. 2, Fig. 3A and Fig. 3B, the composite film restrictor 3 of the present invention comprises a casing 32, a body 34, a throttle member 36, an elastic film 38, and a fine adjustment screw 39. The housing 32 has a source end 321 , a load end 322 , and a first receiving space 323 connecting the source end 321 and the load end 322 . The main body 34 is disposed in the accommodating space 323, wherein the main body 34 has a second accommodating space 341, a third accommodating space 342 connected to the second accommodating space 341, and a first drainage connecting the third arranging spaces 342. In addition, the body 34 further includes a second draining channel connecting the source end 321 and the third receiving space 342. In this embodiment, the outer wall of the body 34 has a groove. In particular, the groove is threaded. However, the inner wall of the body 34 at the second accommodating space 341 is formed with a screw for guiding the fine adjustment screw 39. Further, when the body 34 is disposed in the first space 342, the thread is shaped. The groove system and the housing 32 form a second drain channel R2. The Langling member 36 is disposed in the third housing space 342. The throttle progression includes a throttle ring 361 and a throttle table 362. The throttle ring 361 has a The four accommodating spaces 3611. 3, the flow table 362 is disposed in the fourth accommodating space 3611, and forms a voltage stabilizing chamber 363 and a regulating chamber 364 with the body 4. Moreover, the throttle table 362 M369483 has a communication adjusting chamber. Room 364 and load end 322 1 ritual 3621 〇 elastic film 38 set The fine adjustment screw 39, which is disposed in the second accommodating space 341 and accommodates 342, is disposed in the accommodating portion 341 of the accommodating portion 341. The thickness of the gap between the elastic film 38 and the throttle member 36 is adjusted to the third direction. The fine adjustment screw 39 may be limited between the screw and the table 362. ..., ' In particular, the second accommodating space 341 of the body 34 can be used to guide the fine adjustment screw 39 so that the wall is formed with the internal thread moving up and down. In other words, the screw 39 of the fine adjustment screw 1 can be threaded with the wall. Combining, and utilizing the protrusion 391 to resist the movement of the elastic film 38 along the upper portion of the body 34 by using the fine adjustment lion 39. The pressure on the film 38 and controlling the bomb is controlled by the throttle of the %. The gap size between 362, 8 and the throttling member can be described in detail for the connection position of the two components of the composite film restrictor 3, and the working fluid is entered into the right The composite film restrictor of this creation is moved in Detailed description: Α to: ^ Refer to Figure 2, Figure 3, and Figure 3 'As shown in Figure 2, Figure 3, when I flow in, 'When working fluid 11 is from source 321 of body 34, fluid 12 and working fluid 13 Two bodies or supercritical fluids, but not particularly liquids, gas 8 M369483. In this embodiment, 'the working fluid 12 is connected to the load side by the second drain channel R2 formed by the casing 32 and the body 34. 322 flows. In particular, since the outer surface of the body 34 is grooved, in other words, the second drain channel R2 may be a flow passage formed along the groove. The working fluid 13 is introduced into its plenum chamber 363 via the third draft passage R3 as the flow pressure of the balance load terminal 322. In this embodiment, the working fluid 12 flowing through the second draft passage R2, the working fluid 12 is re-divided into the working fluid 11 and the working fluid 14 as it flows through the first draft passage R1. Wherein, the working fluid Π can flow through the adjustment chamber 364 on the lower side of the elastic film 38 and the gap formed by the tip of the throttle 362 and is further directed toward the load via the inner hole 362 of the throttle 362 of the throttle member 36. End 322 flows out. Specifically, the 'elastic film 38 is a circular elastic material (but not particularly limited thereto), and is attached between the upper edge of the inner ring of the throttle ring 361 and the protruding portion 391 of the fine adjustment screw 39, thereby being stabilized. The pressure chamber 363 is spaced apart from the conditioning chamber 364. The portion of the space formed by the adjustment chamber 364 described above allows the #elastic' film 38 to be bent and moved. Again, it is emphasized that the fine adjustment screw 39 is rotated or retracted by the thread on the inner surface of the body 34, thereby further adjusting the pre-stress of the film 38. In other words, the amount of flexural deformation of the elastic film 38 and the gap between the elastic film 38 and the tip end of the flow table 362 can be finely adjusted by adjusting the fine adjustment screw 39. Finally, the working fluid u and the working fluid 14 will merge into the working fluid 1 at the load end 322. ^ The following is a more detailed description of the operation of the composite film restrictor 3 of the present invention. Please refer to Figure 2, Figure 3A and Figure 3 again. In this embodiment, the amount of deformation of the elastic M369483 film 38 is adjusted by the fine adjustment screw 39 and the throttle table 362, and the gap of the throttle film 362 film is simultaneously adjusted. When the fine adjustment screw 39 is locked, the throttle member % = the gap between the tip end of the flow table 362 and the elastic film 38 becomes small. This: The work of the gap η η the resistance of the change A, and the flow of the red flow 2 becomes smaller, and vice versa, therefore, if the load end 322 increases due to the flow pressure of the load, thereby making the adjustment chamber 364: This will affect the flow imbalance of the plenum chamber 363 and the conditioned chamber 364. At this time, the elastic film 38 is increased by the pressure of the load end 322, so that the pressure of the adjustment chamber 364 is increased, so that the amount of deflection of the elastic film % is increased, and then the throttle table of the throttle member 36 is passed. The flow resistance of the working fluid II in the gap of 362 becomes small, so the change of the guarding force is reversed and vice versa. Therefore, the above mechanism makes the increase and decrease of the working fluid enthalpy flow rate proportional to the flow pressure provided by the load end 322, so that the composite film restrictor 3 made by j can be negatively moved = pressure = dynamic pressure increase and decrease The anti-town mechanism, used to stabilize the load to supplement the enthalpy, the composite (4) membrane throttle 3 ί 2 large change, so that the pressure chamber 363 and the resulting flow pressure difference changes too much, resulting in elastic The large amount of deformation, therefore, the elastic film according to the load end 322 of the flow and the flow pressure to select a better elastic material, the creation = combined type of the throttling H 3 does not limit the material type of the film %. Compared with the prior art, the composite _membrane throttling M369483 of this (4) is quite extensive, and the design of this creation can be used for precision machinery equipped with fluid pressure control. And the composite film restrictor of the present invention utilizes the elastic film and the deformation of the pressure regulating chamber to dynamically control the pressure difference of the working fluid between the source end and the load end, and timely feedback the pressure change of the stable load end, and solve the problem. It is known that the phenomenon of easy wear and blockage and the lack of delayed reaction in the technology. In this way, the composite film restrictor of the present invention can have spontaneous dynamic and dynamic feedback, fast response and fine and fresh control performance, and has the advantages of simple component, convenient assembly and low production cost.
