Abstract
A ball valve capable of adjusting ball wear of a compensating valve comprises a main body, a valve seat, a ball, a valve rod, a stuffing spacer, an O-shaped ring, a compression nut, a handle, a gasket, a nut, an O-shaped ring A, a locking nut and an accessory connector. The ball and the valve seat are positioned inside the main body; the O-shaped ring A is arranged between the accessory connector and the valve seat; the center of the ball is provided with a through hole running through the ball; the valve rod is in threaded connection with the ball; the compression nut, the O-shaped ring and the stuffing spacer are sheathed in sequence between the valve rod and the ball; the handle is arranged at the upper part of the valve rod and provided with the gasket and the nut; the accessory connector and the main body are connected by threads; and the locking nut is positioned on the main body. Compared with a common ball valve in the existing structure, the ball valve capable of adjusting the ball wear of the compensating valve has the advantages as follows: under the condition that poor sealing between the ball and the valve seat is caused by wear, a wear clearance between the compensating valve and the valve seat can be adjusted by rotating the accessory connector, and the ball valve does not need to be replaced or maintained, therefore the production cost is effectively saved and the working benefit is improved.
Description
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 adjustable compensation valve ball wearing and tearing in the pipeline system.
Background technique
Ball valve in the existing technology mainly is to be used for pipeline system control media pressure, the 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 adjustable 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 the sub-joint of ball valve, 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 adjustable compensation valve ball wearing and tearing comprises main body, valve seat, ball, valve rod, Packing seat, O type circle, gland nut, handle, packing ring, nut, O type circle A, locking nut, sub-joint.Ball and valve seat are positioned at main body, O type circle A is arranged between sub-joint and the valve seat, there is a through hole that runs through in ball center, valve rod is threaded with ball, suit gland nut, O type circle, Packing seat successively between valve rod and the ball, handle is assemblied in the top of valve rod, and packing ring and nut are housed on it, sub-joint and main body are by being threaded, and locking nut is positioned on the main body.
The ball valve of the utility model adjustable compensation valve ball wearing and tearing, it is characterized in that, described nuts and washers, play the top effect that handle is fixed on valve rod, the described gland nut that is sleeved on the valve rod rises and compresses O type circle, the effect of Packing seat, the described main body upper locking nut that is positioned at plays locking by being threaded in sub-joint on the main body, described sub-joint and main body are by being threaded, when unclamping locking nut, by the revolute joint, wearing clearance between adjustable compensation valve ball and the valve seat, reach the performance requirement of sealing after, fastening again locking nut.
Usefulness of the present utility model is, compare with the ordinary ball valve in the existing structure, causing because of wearing and tearing between ball and the valve seat under the situation of poor sealing, can pass through the revolute joint, regulate the wearing clearance between compensation ball and the valve seat, need not change or repair ball valve, effectively save cost of production, improve working efficiency.
