Abstract

The utility model relates to a valve, in particular to a novel ball valve. The novel ball valve comprises a valve body, a ball body having through holes in the valve body, a handle, a link axis connecting the ball body and the handle as well as a connecting seat at the side of the valve body. Two blocks arranged on the end surface of the connecting seat are respectively located at both sides of the link axis. The connecting end of the handle is in an arch-shaped. The two blocks are linked with the link axis into a body, forming an opening groove on the end surface of the link axis. Because of the end surface of the connecting seat having a block, the handle position is restricted in open or close state. Therefore the valve has advantages of smooth opening or closing, good stability, convenient application and processing, high utilization materials and long service life.

Description

A kind of ball valve

Technical field:

The utility model relates to a kind of valve, is specifically related to a kind of ball valve.

Technical background:

Existing ball valve is spacing to handle, be to be provided with raised line in the side of handle connecting base, and the connecting end of handle is provided with block, and block is stuck on the side of raised line and plays position-limiting action, and this ball valve is in that to add the man-hour stock utilization low simultaneously, and working life is short.

Summary of the invention:

The purpose of this utility model provides a kind of ball valve, and this ball valve is made simple, and is easy to use.

A kind of ball valve comprises valve body, is located at the coupling shaft of being with spheroid, handle, connection spheroid and the handle of through hole in the valve body, the connecting base of being located at the valve body side, and the connecting base end face is provided with positive stop.

Positive stop is provided with two, is located at the both sides of coupling shaft respectively,

Further two positive stops fuse in a side of coupling shaft, become an open recess at the connecting base end face.

The connecting end of handle is made as circular arc.

Because the connecting base end face is provided with positive stop, when on off state, handle to be carried out spacingly, the two ends of handle are made as circular arc, have the flexible good stability of unlatching, and are convenient to processing, use stock utilization height, advantages such as long service life.
