Abstract

The invention discloses a valve, and belongs to the technical field of valves. The valve comprises a valve body, an outlet assembly, a first cut-off assembly and a second cut-off assembly. The valve body is internally provided with a feeding port and a flow channel, and the feeding port communicates with the flow channel. The outlet assembly comprises a connecting shaft pipe, a push rod and a one-way valve, the first end of the connecting shaft pipe is fixedly inserted into the valve body, the push rod is movably and coaxially inserted into the connecting shaft pipe and protrudes out of the connecting shaft pipe, a valve seat of the one-way valve is connected with the second end of the connecting shaft pipe, and a gap is formed between the inner wall of the connecting shaft pipe and the outer wall of the push rod. The gap respectively communicates with the first end of the flow channel and the feeding port of the one-way valve. The first cut-off assembly comprises a first valve rod, and the first valve rod is movably inserted into the valve body. The second stop assembly comprises a second valve rod, and the second valve rod is movably inserted into the valve body. According to the valve, dual control over the valve can be achieved, and the reliability of the valve is improved.

Description

technical field [0001] The invention belongs to the technical field of valves, and more specifically relates to a valve. Background technique [0002] A variety of liquids and gases are widely used in industrial production, and the storage and use of liquids and gases often use valves. [0003] In the related art, the valve includes a valve core and a valve body. The valve body has an inlet and an outlet, and the connection between the inlet and the outlet is controlled by twisting the valve core, so as to realize the control of liquid or gas on-off. [0004] However, the channel control of the above-mentioned valve through a single spool will reduce the reliability of the valve, and the control of the spool cannot be conveniently realized under the action of high-pressure medium. Contents of the invention [0005] In view of the above defects or improvement needs of the prior art, the present invention provides a valve, the purpose of which is to improve the reliability ...
