Abstract
The utility model discloses an elastic valve seat of a metal seal eccentric valve, which comprises a valve seat, a valve body, an elastic gasket, a pressing ring and an O-shaped ring, wherein the valve seat and the valve body are separated parts; the O-shaped ring is arranged between the valve body and the valve seat; the elastic gasket is arranged between the pressing ring and the valve seat; and the valve seat and the valve body are fastened together through a pressing ring used screw. In the elastic valve seat of the metal seal eccentric valve provided by the utility model, as the elastic valve seat is adopted, the elasticity of the elastic gasket is used for compensating the abrasion of the valve seat and a spherical crown when sealing performance of the valve seat and the spherical crown is lowered due to the abrasion on the valve seat and the spherical crown for a long-term use, so that excellent sealing effect of the valve seat and the spherical crown is permanently retained, and the service life of the valve is prolonged.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of metallic seal eccentric valve elastic seat.
Background technique
Make a general survey of at present domestic and international metallic seal eccentric valve, valve body and valve seat substantially all is the bulk metal casting, the valve seat of this structure, it is relatively all relatively simple to produce installation, but because the spherical crown of valve seat and eccentric crankshaft all is a metal, long-time use can cause wearing and tearing, when wear extent arrives to a certain degree, under the valve rated working pressure, can cause valve seal to reveal, the valve control fails, the serious working life that shortens valve, even cause local pipeline Control Failure, valve is scrapped, cause user cost to improve, and the safety of whole tubing is threatened; And the metallic seal eccentric valve that valve seat, valve body separate, its valve seat and valve body directly are fixed together, and then need to change valve seat when the prooving of valve seat, have the high problem of working service cost.
Summary of the invention
The purpose of this utility model is to provide a kind of metallic seal eccentric valve elastic seat to prolong valve seat and spherical crown because of the deficiency that wearing and tearing cause, and addresses the above problem, and prolongs the working life of valve, reduces the working service cost simultaneously.
To achieve these goals, the utility model is by the following technical solutions: a kind of metallic seal eccentric valve elastic seat, it comprises valve seat, valve body, resilient pad, trim ring and O type circle, wherein valve seat and valve body are divided into two monomer divided portion, be provided with O type circle between valve body and the valve seat, be provided with resilient pad between trim ring and the valve seat, valve seat and valve body tighten together with screw by trim ring.
The utility model metallic seal eccentric valve elastic seat, owing to adopted elastic seat, when valve seat and spherical crown use wearing and tearing to cause sealability to descend for a long time, can remedy valve seat and spherical crown wear extent with the elastic reaction of resilient pad, thereby make valve seat and spherical crown remain good sealing effect, prolong the working life of valve.
Description of drawings
Fig. 1 is the structural drawing of the utility model metallic seal eccentric valve elastic seat.
Embodiment
Below in conjunction with embodiment the utility model is further elaborated.
As shown in the figure, the utility model metallic seal eccentric valve elastic seat, it comprises valve seat 1, valve body 2, resilient pad 3, trim ring 4 and O type circle 5, wherein valve seat 1 is two monomer divided portion with valve body 2, be provided with O type circle 5 between valve body 2 and the valve seat 1, be provided with resilient pad 3 between trim ring 4 and the valve seat 1, valve seat 1 tightens together by trim ring 4 usefulness screws with valve body 2.
As shown in the figure, the utility model metallic seal eccentric valve elastic seat during installation, is installed in O type circle 5 on the valve body earlier, and valve seat 1, resilient pad 3 and trim ring 4 are installed then successively, with screw trim ring 4 and valve body 2 is linked together at last.
