Abstract

A ball valve capable of achieving self-compensation for valve ball abrasion comprises a valve body, a valve rod, a valve ball and a belleville spring. The ball valve is characterized in that the valve ball is arranged in the valve body, a valve seat is arranged between the valve body and the valve ball and connected with the valve body through the belleville spring, and the valve rod penetrates through the valve body to be connected with the valve ball. The self-compensation of valve ball abrasion is achieved through the fact that that the belleville spring is arranged between the valve seat and the valve body, so that when the valve ball is abraded, by the aid of the tension of the belleville spring, abrasion of the valve ball can be adjusted and compensated, and the ball valve seal performance is maintained. Compared with a common ball valve in a prior structure, the ball valve has the advantages that under the condition of poor sealing caused by abrasion between the valve ball and the valve seat, abrasion space between the valve ball and the valve sat can be adjusted and compensated through the belleville spring, and the ball valve is not required to be changed or repaired, so that the structure is compact and simple, the seal is reliable, and the maintenance is facilitated; and the sealing surface and the ball surface are in a closed state, so that the ball valve is not prone to medium erosion, easy to operate and maintain and capable of effectively saving production costs and improving the working efficiency.

Description

The ball valve of self compensation valve ball wearing and tearing
Technical field
The utility model belongs to technical field of valve manufacturing, particularly relates to a kind of ball valve that is applied to the self compensation valve ball wearing and tearing in the pipeline system.
Background technique
Ball valve is simple in structure, good seal performance not only, and driving moment is little, and is easy and simple to handle, easily realize fast opening and closing, is in recent ten years one of valve kind with fastest developing speed.Ball valve is developed by stopcock, and its open-shut device utilizes spheroid to realize the purpose of opening and closing around the axis half-twist of valve rod as a spheroid.Ball valve is mainly used in cutting off, distributes and changes the media flow direction at pipeline, and the ball valve of design forming V-shape opening also has good flow regulating function.The use of ball valve is very extensive, use kind and quantity still continuing expansion, and to high temperature, high pressure, heavy caliber, high leak tightness, long lifetime, good adjusting function and valve multifunctional direction development, its reliability and other performance index all reach higher level, and part replaces gate valve, stop valve, throttle valve.Along with the technological progress of ball valve, in the predictable short time, particularly on the petroleum natural gas pipeline, on the oil refining cracking device and will have on the nuclear industry widely and use.In addition, the big-and-middle-sized bore in other industry, mesolow power field, one of valve types that ball valve also will become to take as the leading factor.Ball valve in the existing technology mainly is for pipeline system control media pressure, flow and the flow direction, it in use needs regular opening and closing, sealability will descend in use for some time, particularly because opening and closing repeatedly, make the sealing system of ball valves such as valve ball produce wearing and tearing, ball valve will not be in sealing state this moment, thereby cause scrapping of product, and the ball valve of this sealing configuration is higher to processing request, and ball valve is a kind of engineering goods that are widely used, production and processing meets the ball valve that sealability requires, need to adopt expensive day by day non-ferrous metal, as brazen valve body, valve seat, valve rod, bonnet, the spool ball, fill bonnet, purple adapter made of copper etc.Make the raw material serious waste, these factors have all caused the manufacture cost of ball valve too high.
Summary of the invention
The purpose of this utility model is at technological deficiency of the prior art, a kind of ball valve of self compensation valve ball wearing and tearing of novel structure is provided, make it in use, can regulate the wearing and tearing of compensation ball valve valve ball by ball valve and butterfly spring, make it reach the requirement that sealability is more excellent, adjusting is convenient.
The purpose of this utility model is achieved by following technological scheme:
A kind of ball valve of self compensation valve ball wearing and tearing comprises valve body, valve rod, valve ball, valve seat, butterfly spring.It is characterized in that, be provided with valve ball in the described valve body, be provided with valve seat between valve body and the valve ball, valve seat is connected with valve body by the butterfly spring, and described valve rod passes valve body and is connected with valve ball.
Further specify, self compensation valve ball described in the utility model wearing and tearing, be described butterfly spring between valve seat and valve body, when valve ball wear and tear, the tension force of butterfly spring, the wearing and tearing of adjustable compensation ball valve valve ball, the sealability of maintenance ball valve.
Usefulness of the present utility model is, compares with the ordinary ball valve in the existing structure, is causing because of wearing and tearing between ball and the valve seat under the situation of poor sealing, can regulate the wearing clearance that compensates between ball and the valve seat by ball valve and butterfly spring, need not change or repair ball valve, compact structure, sealing is reliable, simple in structure, easy to maintenance, sealing surface and the sphere closed state of being everlasting, be difficult for by the medium erosion, cost of production has effectively been saved in easy operating and maintenance, has improved working efficiency.

Drawing reference numeral explanation: 1-valve body, 2-valve rod, 3-valve ball, 4-valve seat, 5-butterfly spring.
Embodiment
Further specify the utility model below in conjunction with Figure of description.
As shown in Figure 1, the ball valve of a kind of self compensation valve ball wearing and tearing described in the utility model comprises valve body 1, valve rod 2, valve ball 3, valve seat 4, butterfly spring 5.It is characterized in that, be provided with valve ball 3 in the described valve body 1, be provided with valve seat 4 between valve body 1 and the valve ball 3, valve seat 4 is connected with valve body 1 by the butterfly spring, and described valve rod 2 passes valve body 1 and is connected with valve ball 3.
The wearing and tearing of described self compensation valve ball, be described butterfly spring 5 between valve seat 4 and valve body 1, when valve ball 3 wearing and tearing, the tension force of butterfly spring 5, the wearing and tearing of adjustable compensation ball valve valve ball 3, the sealability of maintenance ball valve.
