Abstract
The invention relates to a ball valve, which comprises a valve seat, a valve body, a ball valve and a valve stem, wherein the valve body is arranged on the valve seat, and the valve stem is fixedly arranged in the valve body through a bearing; the two ends of the valve body are provided with an inlet and an outlet, and the ball valve is a hollow truncated sphere; the valve and the valve stem are of an integrated structure, and the top end of the valve stem is connected with a handle; and a gasket is arranged between the ball valve and the valve seat, and the inlet and the outlet are provided with elastic gaskets. The ball valve is designed into the truncated sphere, so that the used materials are few, and the weight is light; a wear-resistant pad is arranged at the bottom of the ball valve to reduce the friction of the ball valve on the bottom; and the gasket is arranged between the ball valve and the valve seat to increase the sealing performance. The valve and the valve stem are designed into a whole, accordingly, the ball valve can be firmly controlled by the valve stem, and can not be deformed by pressure.
Description
Technical field
The present invention relates to a kind of ball valve.
Background technique
The ball valve products characteristics of existing market supply is that Ball valve and switch valve rod are split-type structural, very easily causes the damage of Ball valve and valve rod joint and lost efficacy in switch using process frequently, and be difficult to maintenance.Spheroid valve and valve base chamber produce sliding friction like this, do not have again abrasionproof spare, and spheroid valve serious wear easily causes gas leakage, oil leakage phenomenon.Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide a kind of good seal performance, the long ball valve of physical life.
A kind of ball valve, comprise valve seat, valve body, Ball valve and valve rod, described valve body is loaded on the valve seat, described valve rod is fixed in the valve body by bearing, and described valve body two ends are provided with import and outlet, and described Ball valve is hollow intercept sphere, described Ball valve and valve rod are structure as a whole, described valve stem tip is connected with handle, is provided with seal washer between described Ball valve and the valve seat, and described inlet and outlet is equipped with resilient pad.
Described inlet and outlet all is equipped with flange.
Described intercept sphere is 1/5～1/4 of whole spheroid.
Described Ball valve bottom is provided with anti-abrasion pad.
The present invention is designed to hollow intercept sphere with Ball valve, few with material, lightweight, the Ball valve bottom is provided with anti-abrasion pad, reduces Ball valve to the friction of bottom, is provided with seal washer between Ball valve and the valve seat, increase sealing, the present invention is designed to one with valve and the valve rod of intercept sphere, and valve rod is firm when the control Ball valve like this, can not be out of shape because of pressure.
