Ball valve with opening and closing state display function

Abstract

The invention discloses a ball valve capable of displaying opening and closing states, which comprises a rotary handle (1), a valve body (2), a rotating shaft (3), a static buckle (4) connected with the valve body (2), and a handle ( 1) The connected dynamic buckle (5) is characterized in that the static buckle (4) and the dynamic buckle (5) are each extended with a hemispherical protrusion. When the ball valve is in a closed state, The circular planes of the two hemispherical protrusions meet. By means of the circular planes of the two hemispherical protrusions meeting or moving away from each other, the opening and closing state of the ball valve can be visually and intuitively understood, and it is also helpful for the visually impaired to sense by touch.

Description

technical field [0001] The invention belongs to valves, and more specifically relates to a ball valve capable of displaying opening and closing states. Background technique [0002] The opening and closing of the existing ball valves is achieved by turning the handle counterclockwise or clockwise at an angle of 90 degrees. It is fully open when the position of the handle is at right angles to the outlet pipe, which is inconsistent. Also, although many people often use it, they cannot tell the opening direction when asked. However, in actual life or production, the ball valve is often required to have the function of opening and closing state indication. For example, when the upstream of the logistics system unexpectedly stops the transportation, there is no liquid flowing out of the downstream, and the ball valve in the open state is easily mistaken for being in the closed state. Whether it should be closed or not, once the upstream transportation resumes, materials will of...

[0002] The opening and closing of the existing ball valves is achieved by turning the handle counterclockwise or clockwise at an angle of 90 degrees. It is fully open when the position of the handle is at right angles to the outlet pipe, which is not consistent. Also, although many people often use it, they cannot tell the opening direction when asked.

However, in actual life or production, the ball valve is often required to have the function of opening and closing state indication. For example, when the upstream of the logistics system unexpectedly stops the transportation, there is no liquid flowing out of the downstream, and the ball valve in the open state is easily mistaken for being in the closed state. Whether it should be closed or not, once the upstream transportation resumes, materials will often be wasted or safety accidents will occur
