Abstract
The utility model belongs to a control component in a fluid delivery system. The utility model has the technical characteristic that a metal elastic seat is adopted on the basis of keeping the main body structure of a ball valve, a plurality of elastic slots which are used for strengthening the elasticity to improve the sealing performance is arranged on the metal elastic seat, and the flotation is generated by a ball body on the elastic seat. The back of the metal elastic seat is provided with a semicircular elastic ring, a seat valve can be pushed to the ball body, and the reliable seal is obtained. The utility model has the advantages of novel structural design, reliable sealing performance, long service life, and easy cleaning and repair.
Description
The utility model belongs to the controlling component in the fluid delivery system, relates generally to a kind of metallic elastic seat globe valve.
Its valve seat of ball valve in using now adopts (F substantially
4) teflon or nylon material, thereby the structure that its elasticity of corresponding reinforcement improves sealability is not set, wear out after using a period of time, follow the string, even produce nonvolatil distortion, cause the ball valve seepage or scrap, thus as its medium that is suitable for of valve seat of soft seal, serviceability temperature and scope are restricted, and have the defective that working life is short and be difficult for reprocessing.
The purpose of this utility model promptly produces thus, proposes a kind of metallic elastic seat globe valve, makes it have excellent sealing performance, and make its Applicable media, working environment such as serviceability temperature and scope, adaptability are strengthened and are had long working life, thereby solve the problem that above-mentioned ball valve exists.
The technological scheme that the utility model is taked is: on the basis that keeps the ball valve agent structure, the spring support back side of making at metallic material is provided with elastic ring, thus under compaction forces is given in installation, elastic force by the back metal elastic ring is pushed the metallic elastic seat to sphere, when pressure increases also distortion thereupon of elastic ring gradually, rebounding force will advance spring support once more to sphere, can both reach excellent sealing thereby make when the pressure medium height; Set in order to the flexible elastic groove of further raising in valve cup rim, helped the distortion of valve seat and hold the resiliently deformable of seat material.
The utlity model has following characteristics:
1, the flexible groove of the utility model seat design, help the distortion of valve seat and hold the resiliently deformable of seat material, when pressure medium enters groove and valve body central lumen formation pressure difference, force valve seat to be close to ball seal, the Lower Half by seat when pressure is low seals, along with increasing of pressure, the spheroid displacement, the first half pressurized of sealing seat, and further be out of shape, the sealability of valve improved.
2, the design of the back side of metallic elastic seat has the metallic elastic ring, under compaction forces is given in installation, by the back metal elastic ring metallic elastic seat is pushed to sphere, make sealing better, when pressure increases also distortion thereupon of elastic ring gradually, rebounding force will advance spring support once more to sphere, can both reach excellent sealing thereby improve when the pressure medium height.
3, temperature utilization scope is 400 ℃～550 ℃
4, the utility model structure is comparatively novel, long service life and be easy to clean, reprocess.
The accompanying drawing that the utility model embodiment provides is:
Accompanying drawing 1 is the utility model structural representation.
As shown in drawings: agent structure of the present utility model still is to use original ball-valve structure, promptly include valve rod 1 shown in the figure, handle 2, elastic scheibe 3, positioning block 4, Gland 5, filler 6, right valve barrel 7, left valve barrel 10, nut 11, stud 12, hexagonal double-ended bolt 13, nut 14, spheroid 15, all adopt the existing structure of original ball valve, structural design of the present utility model is to adopt metallic elastic seat 8, metallic elastic seat 8 sets several in order to improve the elastic groove 16 that pedestal elasticity helps the distortion of valve seat and holds the resiliently deformable of seat material, elastic groove can set in the several position at spring support 8 edges, be provided with half garden shape elastic ring 9 at the back side of metallic elastic seat 8, in order to push valve seat to spheroid, reach reliable sealing, its concrete structure can be the valve body 7 that contacts with metallic elastic seat 8, semicircle elastic ring 9 is set on 8, set the semi-circular groove of joining with elastic ring 9 kisses in the relevant position of metallic elastic seat 8, spheroid 15 produces on spring support and floats.
Also can select the valve seat material of matched seal pair according to the material of valve body, spheroid for use, carry out surface treatment and sealing surface weld deposit cemented carbide, applicable various different mediums.
Claims (2)
1, a kind of metallic elastic seat globe valve, include left and right sides valve body (10) (7), handle (2), valve rod (1), the spheroid (15) of existing structure, feature of the present utility model is to adopt metallic elastic seat (8), set several on the metallic elastic seat (8) in order to improve the elastic groove (16) that pedestal elasticity helps the distortion of valve seat and holds the resiliently deformable of seat material, elastic groove (16) can set the several marginal positions at spring support (8), is provided with semicircle elastic ring (9) at the back side of metallic elastic seat (8).
2, according to the described metallic elastic seat globe valve of claim 1, feature is to set the semi-circular groove of joining with elastic ring (9) kiss on metallic elastic seat (8).
