Abstract

The utility model discloses a ball valve with a bidirectional limiting device. The ball valve with the bidirectional limiting device comprises a valve body and a valve rod, wherein the terminal end of the valve rod is provided with a limiting cross bar; the valve body is provided with a first limiting bump and a second limiting bump; the second limiting bump extends along the axial direction of the valve body; and the first limiting bump extends along the radial direction of the valve body. The ball valve with the bidirectional limiting device, disclosed by the utility model, has the advantages of being simple and convenient and further providing convenience for users to operate as the first limiting bump and the second limiting bump used for respectively indicating a completely close state and a completely open state of the ball valve are arranged on the valve body.

Description

Ball valve with bidirectional limiting device

Technical Field

The utility model relates to a valve, more precisely, be a take two-way stop device's ball valve.

Background

Ball valves, defined in standard GB/T21465-2008 "valve nomenclature" as: the valve with the opening-closing part (ball) driven by the valve rod and rotating around the axis of the valve rod is mainly used for cutting off or connecting the medium in the pipeline, and also for regulating and controlling the fluid, especially for medium containing fiber, micro solid particle, etc. The valve body of the existing ball valve is generally only provided with a limit projection for indicating a stop position, and no indicating device is arranged on a through position. When the working environment is dark, the user can hardly make the ball valve in a completely through position.

Disclosure of Invention

The utility model discloses solve the technical problem that prior art exists mainly to a take two-way stop device's ball valve is provided.

The above technical problem of the present invention can be solved by the following technical solutions:

the utility model provides a take two-way stop device's ball valve, contains valve body and valve rod, the end of valve rod be equipped with a spacing horizontal bar, the valve body on be equipped with a first spacing protruding and a second spacing protruding.

As the preferred embodiment of the present invention, the second limiting protrusion extends along the axial direction of the valve body, and the first limiting protrusion extends along the radial direction of the valve body.

The utility model discloses a take two-way stop device's ball valve sets up first spacing protruding and the spacing protruding of second on the valve body for instruct completely of ball valve respectively ending and link up these two different states completely, simple and convenient further provides convenience for user's operation.
