Embodiment 1

[0008] Embodiment 1: refer to figure 1 figure 2 . figure 1 The left side is the solenoid valve, and the right side is the manual valve. The valve of the manual valve closes the gas source port, and the moving iron core of the solenoid valve closes the second transition hole. Gas or liquid cannot pass from the gas source port to the gas outlet. Twist the handwheel to make the valve stem and the insert on it rotate synchronously with the handwheel, and at the same time, because the insert is embedded in the slot of the valve, the valve (to the right) that is threaded with the counterbore is forced to move in a straight line, so that the valve is separated from the air source At this time, the gas or liquid enters the sink hole through the gas source port, then enters the first transition hole through the sink hole and stays in the connection port on the left side of the first transition hole, and then applies a working voltage to the electromagnetic coil to move The magnetic ...

Abstract

The invention relates to a mechanical accessory, in particular to a double-purpose valve for gas or liquid delivery equipment. The double-purpose valve comprises a shell, wherein the shell is provided with a mechanism capable of opening or closing a gas source port and a gas outlet. By adopting the technical scheme, the invention organically combines a hand-operated valve with an electromagnetic valve together, thereby extending the use value and enhancing the opening or closing speed of a gas or liquid and the work efficiency.

Description

technical field [0001] The invention relates to a mechanical fitting, in particular to a dual-purpose valve used in gas or liquid delivery equipment. Background technique [0002] The gas or liquid pipeline valves in the prior art rely on manual opening and closing to achieve the conduction or closure of the gas or liquid, which is inconvenient to operate, slow to open and close, and low in work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-purpose valve that can automatically open or close gas or liquid. The technical solution adopted by the present invention to solve the technical problem is: a dual-purpose valve, which includes a shell, and the shell is provided with a mechanism that can open or close the air source port and the air outlet port. The technical problem to be solved by the present invention can be further solved by the following technical scheme: the mechanism that can open ...
