A kind of large scale ring body sealing surface circularity calibrating installation
Technical field
The present invention relates to a kind of installations to assist check tool, specifically a kind of large scale ring body sealing surface circularity calibration cartridge
It sets.
Background technique
Any product, when its size is bigger, then simple structure is also required to repetition test is carried out at its main seal, really
Confidential letter fits together perfectly, and in existing butterfly valve production process, the bore of butterfly valve body is bigger, easier under violent concussion
Deformation, sealing surface are that round and dish plate outer ring contacts sealing, and in normal soft sealing structure, sealing ring is by pressure ring
It is fixed, but the elasticity of fixing bolt can make contact surface have fluctuating when installation, need in pressure testing
It is constantly adjusted at leak.
General installation personnel can use slide calliper rule when checking sealing ring, but bore once on to two meters, often
Need to be equipped with the vernier caliper of three meters or five meters, size is inconvenient greatly, and artificial influence can make during measuring check
It must measure inaccurately, so that test is frequently necessary to repeatedly.
