Valve with self-locking and bidirectional interlocking functions

Abstract

The invention relates to the field of valves, in particular to a valve with self-locking and bidirectional interlocking functions, which comprises a first valve body and a second valve body, the first valve body and the second valve body have the same structure, the first valve body is used for being butted with the second valve body, one end of the first valve body is provided with a liquid inlet, the other end of the first valve body is provided with a liquid outlet, and the liquid inlet is communicated with the liquid outlet; the first valve body and the second valve body are each provided with a plugging device, each plugging device comprises a plugging ball, a driving mechanism, an interlocking mechanism and a locking mechanism, the plugging balls are located in the first valve body and located between the liquid inlet and the liquid outlet, and the plugging balls are used for separating the liquid inlet from the liquid outlet; a through hole for communicating the liquid inlet with the liquid outlet is formed in the plugging ball, the driving mechanism and the locking mechanism are both installed on the first valve body, the driving mechanism is connected with the plugging ball, the driving mechanism is used for driving the plugging ball to rotate till the liquid inlet is communicated with the liquid outlet through the through hole, and the locking mechanism is connected with the driving mechanism. And the interlocking mechanism is installed in the first valve body and connected with the plugging ball, and the interlocking mechanism on the first valve body is further connected with the second valve body, the problem that in a traditional mode, a valve is prone to misoperation, and consequently the valve is opened by mistake is solved, and the effect that the valve is opened by mistake can be reduced.
