Abstract
The present invention relates to rotary drum vacuum valve gate technique field, a kind of device and method for eliminating rotary drum vacuum valve valve element play gap is specifically disclosed.The device includes the pad A and the pad B between valve seat and core assembly installed in cam upper and lower surface, wherein, cam is arranged between core assembly upper end and valve body, and between upper cam surface and valve body contact surface, and the stainless steel gasket A that diameter is identical, thickness is different is installed between cam lower surface and core assembly upper-end contact surface, make to leave appropriate gap between cam and valve body and core assembly；The stainless steel gasket B that diameter is identical, thickness is different is installed between valve seat and the surface that core assembly is contacted, makes to leave appropriate gap between valve seat and core assembly.Using the device and method, each 500 valve opening and closing action tests filled by valve formal dress, upside-down mounting, side are verified, thoroughly avoid core assembly because of valve passage leakage problem caused by axial float.
Description
Technical field
The invention belongs to rotary drum vacuum valve gate technique field, and in particular to one kind eliminates rotary drum vacuum valve valve element and alters
The device and method in dynamic gap.
Background technology
The rotary drum vacuum valve used in uranium enrichment system is needed with valve element detent mechanism, and its effect is regulating valve
The position of core assembly simultaneously makes its axial displacement control in minimum scope to ensure the sealing of valve passage.Mesh
The valve element detent mechanism of smaller diameter valve is to add transverse direction using screw support in cam and valve seat location in preceding system
The structural shape of jackscrew.Because valve aperture is small, core assembly lighter weight, positioned between cam and valve element,
Cam is positioned in itself and the positioning method between valve seat and valve element is less demanding to the installation position of valve, is held
Easily meet the passage seal request that valve is installed in each orientation.
As the increase of uranium enrichment production capacity, pipe diameter increase, rotary drum vacuum valve bore increases therewith,
Valve element weight is multiplied, in addition the influence of valve vibration, and screw and jackscrew are only leaned on when valve is reverse mounted
Weight to bear valve element can cause screw loosening and cause valve element to misplace and produce valve passage to leak.
The content of the invention
It is an object of the invention to provide a kind of device and method for eliminating rotary drum vacuum valve valve element play gap,
Can ensure valve cam, valve element, valve seat installation positioning, and core assembly do not occur it is unacceptable
Axial float, it is ensured that effective sealing of passage.
Technical scheme is as follows：A kind of device for eliminating rotary drum vacuum valve valve element play gap, the dress
The pad B including the pad A installed in cam upper and lower surface and between valve seat and core assembly is put,
Wherein, cam is arranged between core assembly upper end and valve body, and in upper cam surface and valve body contact surface
Between, and install that diameter is identical, thickness is different between cam lower surface and core assembly upper-end contact surface
Stainless steel gasket A, make to leave appropriate gap between cam and valve body and core assembly；In valve seat and valve
The stainless steel gasket B that diameter is identical, thickness is different is installed between the surface of core assembly contact, makes valve seat and valve element
Appropriate gap is left between component.
Described pad A and pad B is stainless steel gasket, and it is processed by flow harden.
Described cam upper and lower surface installs the thickness of pad A, and pad B between valve seat and core assembly
Thickness, it is ensured that the axial location of core assembly and the centering of valve port.
A kind of method for eliminating rotary drum vacuum valve valve element play gap, the method specifically includes following steps：
Step 1, install between cam and valve body, and between cam and core assembly that diameter is identical, thickness
Different stainless steel gaskets, positions to cam；
Step 2, install between the surface that core assembly and valve seat are in contact that diameter is identical, thickness is different not
Rust steel plate washer, realizes core assembly and valve port centering.
Remarkable result of the invention is：A kind of elimination rotary drum vacuum valve valve element play gap of the present invention
Device and method, core assembly transferred force on fixed valve body using pad, makes it without upper and lower play
Possibility, reach the sealing of valve passage；Using the device and method, by valve formal dress, upside-down mounting,
Each 500 valve opening and closing action tests checking of side dress, thoroughly avoids core assembly because axial float causes
Valve passage leakage problem.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
As shown in Figures 1 to 3, a kind of device for eliminating rotary drum vacuum valve valve element play gap, including installed in convex
The pad A5 and the pad B6 between valve seat 4 and core assembly 3 of 1 upper and lower surface are taken turns, wherein,
Cam 1 is arranged between the upper end of core assembly 3 and valve body 2, and is contacted with valve body 2 in the upper surface of cam 1
Install that diameter is identical, thickness between surface, and between the lower surface of cam 1 and core assembly upper-end contact surface
The different stainless steel gasket A5 of degree, makes to leave appropriate gap between cam 1 and valve body 4 and core assembly 3,
Realize rotating requires；Install that diameter is identical between valve seat 4 and the surface that core assembly 3 is contacted, thickness not
Same stainless steel gasket B6, makes to leave appropriate gap between valve seat 4 and core assembly 3, to realize rotating
It is required that；The adjustment upper and lower surface of cam 1, and pad A5 and pad between valve seat 4 and core assembly 3
The thickness of B6, realizes the axial location of core assembly and the centering of valve port；Cam 1 is while valve element is positioned
Need to carry out self poisoning.Pad A5 and pad B6 is processed by flow harden, to ensure its wearability,
Meanwhile, roughness needs to reach certain requirement, to reduce the frictional resistance in transmission.
