Abstract
The utility model relates to an electrical anti-shear low viscosity-breaking flow controlling device, comprising a valve body, a valve cap, a valve core and a sealing gasket, which is characterized in that the utility model is provided with a valve core with two cone-shaped ends. The valve core is fixed inside the valve body with a conic cavity, wherein, the direction of inlet of the valve body is vertical to the direction of the outlet. The conic cavity comprises a plurality of bushings of taper hole. A fluent runner channel with gradual changing cross-sectional area is formed between the valve core of outer cone part and the valve chamber of inner taper hole, which ensures the fluid in the flow controlling device in steady flow state. A stuffing box is arranged on the upper part of the valve cap and an O-shaped sealing ring is arranged in the central section, which is used for sealing the valve cap. A guide bearing is arranged on the lower part of the valve cap, which is used for supporting and guiding the valve core in order to avoid the seizure phenomenon caused by the up-and-down movement of the valve cap and the parts movably matched with the valve core. The electric actuator can accept 4 to 20 mA control current to control the opening of the valve core. The utility model has the advantages of resisting shear, reducing the viscosity, sealing the valve cap reliably and self controlling and adjusting the flow.
Description
Technical field the utility model relates to a kind of flow regulator, and what be specifically related to is the electronic anti-shearing sinking viscosity flow quantity regulating device that is used for high viscosity liquid control usefulness.
The background technology flow regulator is a kind of product of realizing flow control in the automation field.In occasions such as high pressure, high viscositys, if when using common high pressure flow variable valve or high pressure flow regulating device to regulate flow, because stream complexity, fluid resistance is big, exists stronger shear action, and high molecular high viscosity liquid molecular chain rupture will take place, destroyed macromolecular structure, cause viscosity to reduce, increase cost, wasted the energy, be unfavorable for energy-conserving and environment-protective.
The summary of the invention the purpose of this utility model is for solving the limitation and the shortcoming of existing common high pressure flow variable valve or high pressure flow regulating device, a kind of electronic anti-shearing sinking viscosity flow quantity regulating device that can bear anti-shearing low viscosity reduction, valve gap positiver sealing, flow automatic control adjusting being provided.
The purpose of this utility model is achieved in that electronic anti-shearing sinking viscosity flow quantity regulating device comprises parts such as valve body, valve gap, spool, gasket seal.The characteristics of this electronic anti-shearing sinking viscosity flow quantity regulating device are that the flow regulator design has the double end cone spool, it is installed on the valve inner of importing and exporting rectangular conical internal cavity, the conical internal cavity of valve body is made up of 3-4 section taper hole straight tube, cone spool and internal taper hole valve pocket form smooth slick and sly stream outside, guarantee to be in by the fluid of flow regulator the flow state of gradual change current stabilization.Valve gap top is provided with stuffing-box, and the middle part is provided with O-ring seals, guarantees valve bonnet seal.And be provided with guide bearing in bonnet lower, and spool is carried out support guide, avoid valve core movement to produce and kill phenomenon.Electric operator is accepted the Control current of 4～20mA, control spool aperture.Realized the purpose that anti-shearing low viscosity reduction, valve gap positiver sealing, flow automatic control are regulated.
Description of drawings:
Fig. 1 is the structural representation of the utility model example;
Embodiment is described in further detail below in conjunction with the relevant structure and the principle of work of accompanying drawing to utility model.The utility model comprises endpiece flange (1), more piece taper hole lining (2), valve body (3), double end poppet valve core (4), guide bearing (5), valve body O shape circle (6), valve gap O shape circle (7), valve gap (8), online replacing filler (9), gland (10), electric operator compositions such as (11).Electric operator (10) is installed on the valve gap (8), and it accepts the control signal from 4～20mA of host computer, reaches certain aperture position by the power drive spool.Endpiece flange (1), more piece taper hole lining (2) and valve body (3) are by being welded to form the flow regulator body.The internal taper hole of double end poppet valve core and regulating device body forms the runner path that two ends are the cross-sectional area gradual change, arrow among Fig. 1 is the flow direction of medium, entrance point device intracavity section is long-pending to be diminished to the throttling runner gradually by normal runner, and becomes big to normal runner gradually at the endpiece sectional area.For the macromolecule high viscosity liquid, because the gradual change principle of runner design, guaranteed that high viscosity liquid in by throttling and be unlikely to saboteur's chain, has kept the original characteristic of macromolecule high viscosity liquid to greatest extent.And in the design link of valve bonnet seal, except the valve gap O shape circle (7) that adopts high pressure to use, also increased online interchangeable filler (9), when using, reality can prevent just in case when valve gap O shape circle (7) wearing and tearing back generation was lost efficacy, also have second road to seal online interchangeable filler (9) and compress the realization sealing by gland (10), even online interchangeable filler (9) lost efficacy, also can on-the-spotly change, maintain easily.Because the guiding position of valve gap and spool belongs to movingly, be the metal to metal contact, in order to prevent to use metal to kill mutually for a long time, wear-resistant anti-abrasive guide bearing (5) is arranged in the design of the guiding position of spool.Like this, electric flow regulating device complete machine has just been realized the purpose that anti-shearing low viscosity reduction, valve gap positiver sealing, flow automatic control are regulated.
