Abstract
The utility model relates to a linear-type control structure of valve flow, which comprises a valve body and a valve clack, wherein the valve clack has a conical sealing face and a cone for linear-type flow control is disposed on the lower part of the conical sealing face of the valve clack. The structure is characterized in that the structure with the linear-type flow feature is disposed on the valve clack of the valve, so that precise linear-type adjustment of flow is realized, front-back differential pressure of the valve is effectively adjusted, instability of a high pressure difference is relieved and operations of the valve become more stable.
Description
Technical field
The utility model relates to a kind of valve, particularly can regulating valve import design with the linear structure of outlet pressure reduction and flow control.
Background technique
Valve is to control fed sheet of a media by the cooperation of valve body and flap, after valve closing, its entrance point is different from the pressure of outlet end, produce pressure reduction, when the existence of pressure reduction can cause medium to pass through valve, valve part and pipeline are produced to huge impact force, cause the flow of valve that strong variation occurs, affect the performance and used life of whole equipment, for the extremely strict pipe-line system of flow control, particularly High Temperature High Pressure system, existing valve type line structure can not meet the requirement accurately of smooth operation, control accuracy.
Summary of the invention
The purpose of this utility model is to provide a kind of valve flow straight line type control structure, by the aperture of automatic regulating valve door, adjusts valve inlet/outlet pressure reduction, realizes smooth operation, the usability of precise control of flew.
Technical solution of the present utility model is: a kind of valve flow straight line type control structure, comprise valve body and flap, and it is characterized in that being that valve clack sealing surface is conical seal (contact) face, be provided with the taper of flow straight line type control in the bottom of flap conical seal (contact) face.
The utility model is according to Flow characteristics requirement, sealing surface on flap is designed to conical seal (contact) face, is designed to cone structure in the sealing surface bottom of flap, to meet the requirement of valve flow straight line type control simultaneously, realize flow straight line type and accurately controlled, guaranteed system stable operation.
Feature of the present utility model is: by be provided with the structure with straight line type Flow characteristics on the flap of valve, realize flow straight line type fine adjustment, the effectively front and back pressure reduction of regulating valve, has alleviated the unstability of High Pressure Difference, makes the operation of valve more steady.
Accompanying drawing explanation
Fig. 1 is the partial structurtes schematic diagram of the utility model valve.
Embodiment
As shown in Figure 1, valve flow straight line type control structure is, on the flap 4 matching with valve body 1, conical seal (contact) face 2 is set, the flap part that the bottom of flap conical seal (contact) face can be stretched to valve channel inside is made taper 3, for the adjusting control of flap flow.When electric valve driving mechanism is according to the feedback of signal, drive the valve rod being connected with flap to move up and down, by conical seal (contact) face and the taper structure of flap, realize and under High Pressure Difference condition, remain linear Flow-rate adjustment, meet the accurate control of flow simultaneously, made the operation of valve more steady.
Claims (1)
