[0030] The fluid can be liquid or gas.

[0031] The fluid inlet 102 is connected with a fluid conveying device, and then the fluid flows out from the fluid outlet 103 after passing through the control cavity 101.

[0032] The control block 201 is fixedly connected with a first sealing ring 202 and a sealing pad 203 at the bottom, respectively; the sealing pad 203 can be attached to the inner wall of the fluid outlet 103, and the first sealing ring 202 and the sealing pad 203 are fixed at the bottom of the control block 201 in the form of strong glue.

[0033] When the fluid needs to be cut off, and the flow is not needed, at this time, the gas cylinder 2 is started, the driving control block 201 moves downward, the first sealing ring 202 is attached to the top of the fluid outlet 103, the first sealing ring 202 is deformed under the force, and the sealing effect is achieved, at the same time, the sealing gasket 203 is also inserted into the fluid outlet 103, the sealing gasket 203 is extruded and tightly attached to the inner wall of the fluid outlet 103, further achieving the sealing effect, so that the fluid cannot flow out through the fluid outlet 103.

[0034] Through the cooperation of the first sealing ring 202 and the sealing gasket 203, the sealing effect is achieved, compared with only using a single first sealing ring 202 to seal, the stability is greatly improved, and long-term high-frequency work is achieved, even if the first sealing ring 202 or the sealing gasket 203 is worn, as long as it is not worn at the same time, leakage will not occur, and the stability is greatly improved.
