Ball gate type valve distinguishable in open and closed state

Abstract

The invention discloses a ball gate valve capable of distinguishing open and closed states, which comprises a capped rotary handle (1), a valve main body (2), and the valve main body (2) extends vertically upward from a place near the cap There is a rod with a circle (3) at the end, and the handle (1) extends vertically downward with a rod with a small ball (4) at the end. When the ball valve is in a closed state, the circle hole of the circle (3) happens to be Let the pellets (4) fill. By means of whether the small ball (4) is filled in the hole of the circle (3), the closed or open state of the ball valve can be visually distinguished, and it is also helpful for the visually impaired to perceive with the tactile sense of fingers.

Description

technical field [0001] The invention belongs to valves, and more specifically relates to a ball gate valve capable of distinguishing opening and closing states. Background technique [0002] Existing ball gate valves or ball valves for short, some are fully open when the handle position coincides with the liquid outlet pipe, and some are fully open when the handle position is at right angles to the liquid outlet pipe, which are not unified. , although many people often use it, once they are asked about the position of the handle in the open and closed state, they can't tell. In actual life or production, ball valves are 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 fully open state is easily mistaken for being in the closed state. , so that the gate is not closed, once the ups...

[0002] Existing ball gate valves or ball valves for short, some are fully open when the handle position coincides with the liquid outlet pipe, and some are fully open when the handle position is at right angles to the liquid outlet pipe, which are not unified. , although many people often use it, but once they are asked about the position of the handle in the open and closed state, they cannot tell clearly

In actual life or production, ball valves are 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 fully open state is easily mistaken for being in the closed state. , so that the gate is not closed, once the upstream transportation resumes, materials will often be wasted or safety accidents will occur
