Description

Valve seat convenient to adjust

Technical Field

The utility model relates to the technical field of connecting tools, in particular to a valve seat convenient to adjust.

Background

And the valve inner detachable surface part is used for supporting the valve core at the full closing position and forming a sealing pair. The diameter of the valve seat is the maximum flow diameter of the valve. For example, the valve seat of the butterfly valve is made of very wide range of materials, and various rubber, plastic and metal materials can be used as the valve seat materials, for example: EPDM, NBR, NR, PTFE, PEEK, PFA, SS315, STELLITE, et al, use a resilient sealing material and a small actuator thrust to achieve a bubble-tight seal, and compressive valve seat sealing stresses elastically deform the material to squeeze into the roughened surface of the mating metal part to block the entire leakage path. The permeability of the material is the basis for small leaks for fluids, the material is too soft, or cold deformation (creep) occurs under load, and fillers such as glass fibers can be added to stiffen it. If used in sheet form, the requirements of use are still met, cold deformation or permanent deformation can be eliminated, and the seal must be carefully secured to prevent cracking and leakage due to differential pressure. Bonding of the soft valve seat to the metal part is one approach, but does not completely solve the problem, as the bond breaks and fails when subjected to thermal shock. A sufficiently large pressure drop will destroy the bonding material.
