Abstract
The utility model discloses a corrugated ball valve, which is characterized in that an elastic corrugated sealed element is arranged between a valve body and a ball body. The elastic corrugated sealed element comprises a sealing ring which clings with the ball body, a supporting ring which is connected with the sealing ring and an elastic corrugated ring which is connected with the supporting ring. The corrugated ball valve has the advantages of high and low temperature resistance, abrasion resistance, scratch resistance, corrosion resistance, good sealing and no leakage, thus the utility model is applicable for the truncation and dredging of high and low temperature fluid, the fluid with solid particles or corrosive fluid.
Description
Technical field
The utility model relates to a kind of ball valve, specifically relates to a kind of Ripple ball valve with elastic corrugated sealing component.
Background technique
The structure of conventional ball valve comprises valve rod, valve body, spheroid, upstream seal circle, downstream seal ring.Blocking and dredging of upstream and downstream fluid is to rotate the duct that makes on the spheroid medial axis by the spheroid in the body cavity in valve body to communicate with the upstream and downstream mouth of pipe and realize.The installation sealing component is the parts for preventing to leak between spheroid and valve body, the sealing member comprises the seal ring that links to each other with spheroid, the bracing ring of fixed seal ring, be installed in the O type circle on the bracing ring, for guaranteeing that whole sealing component has certain elasticity, O type circle adopts flexible material manufacturings such as rubber, it is high temperature resistant, low temperature tolerance ability is poor, easy to wear, special when having solid particle in the fluid, solid particle is easy to wear or scratch O type circle, cause leakage, reduced the using value of ball valve, for raising is applicable to high temperature, the using value of the cryogen and the ball valve that blocks and dredge of the fluid that has solid particle, for overcoming the shortcoming of prior art, the special the utility model that proposes.
Summary of the invention
The purpose of this utility model is to provide a kind of Ripple ball valve, this Ripple ball valve is flexible ripple sealing component between valve body and spheroid, this member adopts metallic material, heat-resisting quantity, lower temperature resistance, wearability, scratch resistant, corrosion resistance all are enhanced, good airproof performance, do not leak, be applicable to high temperature fluid, cryogen, have the blocking and dredging of fluid, corrosive fluid of solid particle.
Technological scheme provided by the utility model is: Ripple ball valve comprises the seal arrangement between valve body, spheroid, valve body and the spheroid, the sealing device is elastic corrugated sealing component, this elastic corrugated sealing component comprises: seal ring, bracing ring, crimp ring, their Placement is: seal ring one end margin loop wire is pressed against the land portions of described spheroid, forms potted line; The inner chamber of valve body is provided with bracing ring, and bracing ring has annular groove near on spheroid one side, and the other end of seal ring is installed in the annular groove of bracing ring; Bracing ring is away from being provided with crimp ring between side of spheroid and the valve interior wall, and crimp ring one end is fixedlyed connected with bracing ring, and the crimp ring the other end is fixedlyed connected with valve interior wall.
Preferred version provided by the utility model is: elastic corrugated sealing component also comprises spring, packing ring, their Placement is: a plurality of uniform circular blind holes are arranged as spring seat on the bracing ring external diameter end face, spring is installed on wherein, and the other end of spring contacts with valve body; Between bracing ring external diameter and the valve body packing ring is arranged, packing ring is fixedlyed connected with valve interior wall, and the packing ring another side contacts with the bracing ring surface;
Another preferred version provided by the utility model is: elastic corrugated sealing component is installed in ball valve upstream and downstream one end.
Another preferred version provided by the utility model is: elastic corrugated sealing component is installed in two ends, ball valve upstream and downstream.
The utility model has the advantages that:
1, elastic corrugated sealing component of the present utility model all adopts metallic material, high temperature resistant, the low temperature tolerance ability of ball valve have been improved, overcome O type circle adopt flexible material such as rubber etc. can not be high temperature resistant, the shortcoming of low temperature,, be applicable to blocking and dredging of high temperature, cryogen.
2, bracing ring and crimp ring all adopt metallic material, have overcome O type circle and have easily been scratched the shortcoming that causes leakage by solid particle wearing and tearing, are applicable to blocking and dredging of the fluid that has solid particle.
3, elastic corrugated sealing component of the present utility model all adopts metallic material, and good corrosion resistance is applicable to blocking and dredging of corrosive fluid.
4, the utility model adopts elastic corrugated sealing component, utilize the elasticity of crimp ring and the elastic force effect of spring, guarantee that spheroid is on the shaft axis of body cavity all the time, reach reliable sealing effect, crimp ring has higher telescopic resilience, make bracing ring action freely under sealing state, the possibility of avoiding valve body to rise splitting.
5, the utility model adopts elastic corrugated sealing component to improve the sealing reliability and the application area of bracing ring member greatly, makes that the ball valve that has the bracing ring member has obtained using more widely.
