AI Technical Summary
Technical Problem
When replacing the seat of an eccentric rotary valve, it is difficult to visually confirm that the sealing surface matches, leading to multiple adjustments and inconvenience in replacement.
Method used
The valve seat uses a combination structure of sleeve, mandrel and pressure ring, and through the design of measuring window and stepped layer, it can accurately measure and process the sealing end face of the valve seat, so as to ensure the precise fit between the valve seat and the valve core.
Benefits of technology
This improves the accuracy and efficiency of valve seat replacement, reduces connection gaps, and ensures the sealing effect of the valve body.

Abstract
The utility model discloses a kind of eccentric rotary valve valve seat calibration tooling, comprising: sleeve, with first end and second end, first end is screwed in the flow passage entrance of valve body inside;Core shaft, with first sealing end surface that is in valve body and can be contacted with the abutting contact of valve core spherical surface and second sealing end surface located in sleeve;Valve seat, install into sleeve through sleeve second end and make the third sealing end surface of valve seat with second sealing end surface is matched and abut on second sealing end surface;Compression ring, for abutting contact of valve seat in sleeve and third sealing end surface with second sealing end surface;Wherein, sleeve is opened at least one measuring window at valve seat position;The utility model can solve eccentric rotary valve when being repaired and replaced to valve seat, whether the sealing surface of replaced valve seat and the spherical sealing surface of valve core are consistent needs to be determined again, and because the connecting surface of two is in valve body interior, it is difficult to visual, thus need to debug many times, there is the problem of inconvenient valve seat replacement.
