When the external pressurized fluid passes through the throttle and closes the gap due to the frictional resistance, it is used to adjust the working force and the section of the diaphragm restrictor. The gap between the top surface of the flow table and the film changes to change the flow resistance. Since the film is made of elastic material, it has the ability to be subjected to pressure deformation. When the working pressure of the oil chamber rises, the film will be affected by the pressure side. Deformation, and increase the _ shirt, on the contrary, under the work pot (four), the fine deformation is also relatively reduced 'to reduce _ increase the miscellaneous, (four) than the unit pressure _ shape measured in the material and thickness of the film itself, the present invention in order to make _ section When the flow is matched with the working bar 201137554, the 4th die thickness or the assembly clearance', and when both are changed, the main and most of the components can be replaced (4) - "The variable throttle capacity of the film throttle includes the upper throttle The table, the upper spacer ring, the film, the lower spacer ring and the lower throttle table have the structural form as shown in the first figure; the throttle table includes the oil inlet hole, the oil inlet groove, the throttle hole and the oil outlet hole, and the upper oil inlet hole And the inlet end screw of the lower oil hole It is used to install the oil inlet nozzle. The screw hole at the outlet end of the oil outlet hole is used to install the oil nozzle. The upper and lower two flow tables are separated by two upper and lower ones. The space between the clothes is a film, and the upper and lower two flow tables are multi-bolted. Locking and combining, so that the two flow tables clamp the two spacer rings, the two spacer rings are tightly pressed, and the gap between the J clothes on the P is blocked by a ring seal, and the upper and lower spacer rings are sealed with a 0 ring. The leakage barrier between the lower spacer ring and the lower throttle tube is blocked by the Q-ring oil seal. The P-supply oil enters the oil inlet hole of the upper and lower two-stage flow table respectively, enters the oil inlet groove, and then passes through the throttle table. The gap between the throttle surface and the film, the oil supply occurs, and the shoulder is the working pressure, then enters the orifice, continues to flow to the oil outlet, and the outflow restrictor is connected to the bearing oil chamber through the oil pipe. 〃 Two spacer rings are installed between the throttle tables, and the same difference between the two-jaw faces of the reference surface of the spacers is added to the design touch: plus the thickness of the film—half is equal to the thickness of the spacer ring, and the interval _ The width of the ring groove is equal to _ thickness of the half, the width of the ring groove formed by the two spacer rings is equal to _ thickness, and the spacer ring is snail Fixed between the two flow tables, 'the film is clamped between the two spacer rings, and the throttling surface of the film to the throttle table forms the mounting hole. The gap is equal to the thickness of the spacer ring. Remove the distance from the reference surface of the spacer ring to the throttle table and then subtract one-half of the thickness of the film. If the gap is constant when the film thickness is increased, the ring groove formed by the spacer ring is widened, and the increase of the 201137554 s/gap is equal to the capture. The increase in thickness, if the bribe is also increased, the increase in the thickness of the s clothing is equal to the sum of the increase of the two. If the assembly gap is increased and the thickness of the film is not limited, the width of the ring groove formed by the spacer ring is constant, and the spacer ring is The thickness increase is equal to the increase of the gap, so the initial gap of the film and the thickness of the film are changed. The thin film has the elasticity. When the pressure of the upper and lower chambers is different, the film has the effect of the difference between the upper and lower sides. Produce a lion with the effect of mixing and flow. 'When the pressure difference is increased, the amount of thin decrement increases, the side with higher pressure. The opening increases, causing the flow resistance to decrease and the flow rate rises. Conversely, the side with less pressure Opening and subtracting j causes the flow resistance to rise When the pressure difference between the two chambers decreases, the deformation of the film decreases, the small flow resistance increases, the large flow resistance decreases, the flow difference decreases, the film material is changed or the film thickness is changed, and the deformation ability of the film to adjust the working pressure can be changed. In addition, the assembly gap between the film and the throttle table can also be changed, thereby changing the deformation ability of the film corresponding to the initial flow rate per unit, thereby also changing the deformation ability of the film regulating working pressure. [Embodiment] The present invention is capable of changing the deformability of a film for changing the working pressure of the throttle to adjust the working pressure of the hydrostatic bearing oil chamber. When the external pressurized fluid passes through the gap of the restrictor, the flow is caused by the viscous frictional resistance. Resistance, used to adjust the working pressure, refer to the second figure to illustrate the implementation of its working principle. The film restrictor uses the gap between the top surface of the column 115 and 116 and the film 12〇 to change the flow resistance. Since the film 120 is made of an elastic material, it has the ability to be deformed by the pressure 201137554, when the oil chamber When the working pressure rises, the film 12G will be deformed by the pressure, and i will add a gap to reduce the flow resistance. Conversely, when the working pressure drops, the deformation of the film 120 is also relatively reduced, so that the gap is reduced and the flow resistance is increased. The deformation amount of the film (10) according to the unit pressure depends on the material and thickness of the _(3) itself. In order to make the film restrictor change the thickness of the film 12 装配 or the assembly gap, and change both at the same time, the film restrictor can not be older. And most of the components. The present invention is a "film regulating device with variable adjustment capability". As shown in the second figure, the upper throttle block 115, the upper spacer ring 131, the film 120, the lower spacer ring 132 and the lower throttle table 116 are included. The structural form is as shown in the second figure; the throttle tables 115, 116 include oil inlet holes 111' 112, oil inlet grooves 113, 114, orifices 121, 122 and oil outlet holes I23, I24, and upper oil inlet holes 111. And the inlet end screw hole of the lower oil hole m is used for installing the oil inlet nozzle, and the screw hole of the outlet end of the oil outlet hole 123, 124 is used for installing the oil nozzle, and the upper and lower two ring spacers between the upper and lower two flow tables 115 and 116 Between 13 and 132 is a thin 臈 2 〇, the upper and lower turrets 115, 116 are combined with a plurality of throttles 115, 116, and the two turrets 115, 116 clamp the two spacers. 13b 132, two spacer rings 13 132 clamp film 120, the upper throttle table 115 and the upper spacer ring 131 are blocked by the ring seal oil seal 133, and the upper and lower two spacer rings 131, 132 are blocked by the ring seal The lower spacer ring 132 and the lower throttle table 116 are blocked by the annulus oil seal 135. As explained in the second figure, 'the external oil supply enters the oil inlet holes 111 and 112 of the upper and lower two-stage flow tables 115, respectively, enters the oil inlet grooves in, 114, and then flows through the throttle surface 1521 of the throttle tables 115 and 116. a gap between the 1522 and the film 120, after the oil is throttled and adjusted to the working pressure, enters the orifices 121, 122, and continues to flow to the oil outlets 201137554 123, 124 'flow out of the throttle through the oil pipe to Bearing oil chamber. As shown in the second figure, the thickness of the spacer rings 131 and 132 and the relationship between the groove depth and the thickness of the film, the upper spacer ring 131 and the lower spacer ring 132 clamp the film (10) to the ring groove 145 formed by the two spacer rings 13 and 132. To change the width of the ring groove, to change the reference surface of the women's film 120, and to change the film 12 〇 assembly gap, when replacing the film of different thickness 12 根据 according to the use requirements, install the upper reference surface of the film 12 〇 The distance between the 1531 and the lower reference surface 1532 and the contact surface of the upper and lower spacer rings i3i and 132 is 151/2 of the thickness of the film 120, and the distance between the fixed film 120 mounting reference surfaces 1531 and 1532 to the coffee ring reference φ 1511 and 1512, respectively. Can not affect the film! 20 Before the assembly gap is lifted, the film 12 of different thicknesses is fixed on the reference surface ΐ53ι of the upper spacer ring 131 and the lower film 132 of the mounting film 12〇. As shown in the fourth figure, the width of the ring groove 145 formed by the two spacer rings (3) and 132 is increased from the thickness of the film 12'' spacer ring (3), 132 reference surface ΐ5ΐι, ΐ5ΐ2 and the height of the flow surface 152b 1522. The difference plus the design gap plus one half of the thickness of the film 120 results in the thickness of the spacer rings (3), 132; therefore, the thickness of the film 12 is increased, and the width of the ring groove 145 formed by the two coffee rings m, 132 is used, and vice versa. The small film 12 〇 thickness 'is used to reduce the width of the ring groove 145 formed by the two spacer rings 13 132. As shown in the fourth figure, the present invention reduces the assembly and the thickness of the _l2G is constant. The upper _ ring 131 and the lower spacer ring 132 are changed in thickness to make the film 12 〇 and the upper shunt surface 1521 and the lower throttle surface 1522. The gap between the 12 〇 assembly gaps is changed. When the thickness of the ring is increased, the assembly _ is small, and when the film thickness is not k', the thickness of the spacer ring is increased.荦(4) 五骑本(4) Increase _ 12G thickness and _ unchanged real two spacer rings 1 (four) ring fa Α equals the thickness of film 120, the thickness of each spacer ring (3), 132 increases equal to the increase of half film thickness , ρ, upper compartment private 131 and lower spacer ring 132 women's 'interval (four), 132 reference surface 15 ιι, ΐ 5 ΐ 2 and throttle surface,

In the case of the silk case of the present invention, the enamel film 120 is thickly disassembled, and the upper spacer ring (3) and the lower spacer ring 132 are changed in thickness, and the width of the _(4) formed by the two spacer rings m and m is increased or decreased. The width of the ring groove is equal to the thickness of the film 12G which is increased or decreased. When the film thickness is increased, if the gap is also increased, the increase of the thickness of the inter-φ ring is equal to the sum of the two increases; if the gap is reduced, the spacer ring 13 The change of the thickness of the 132 is equal to the sum of the changes of the two; if the assembly gap is increased and the thickness of the film 120 is constant, the ring grooves 145 formed by the two spacer rings (3) and 132 are unchanged, and the thickness of the spacer 13 132 is equal to the gap.
