Technical Field
[0001] The utility model relates to the field of valves, in particular to a valve core extrusion type valve. Background Art
[0002] The existing electromagnetic valves used in the water circuit control are complex in structure. When the workpiece is polished, the polishing liquid is corrosive and contains some abrasive particles, which can easily corrode the electromagnetic valve and cause leakage. Utility Model Content

[0005] According to another embodiment of the utility model, the elastic valve core is further comprised of a rubber valve core.
[0006] According to another embodiment of the utility model, a pneumatic joint is further installed at the air port.
[0007] According to another embodiment of the utility model, pipe fittings are further installed at the openings at both ends of the valve cylinder, and both ends of the elastic valve core are respectively connected to the two pipe fittings.
[0008] According to another embodiment of the utility model, a sealing ring is further provided between the pipe fitting and the opening of the valve cylinder.
[0009] The beneficial effect of the utility model is that the utility model fills gas into the valve cylinder through the gas port, and uses the gas pressure in the cylinder to squeeze the elastic valve core to close the valve. Exhausting the gas can make the elastic valve core rebound, and the valve reopens. The application simplifies the structure and prolongs the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model; Figure 2 It is a cross-sectional view of the utility model.
[0015] A valve core extrusion valve comprises a valve cylinder 1, an elastic valve core 2, a pipe fitting 3 and an air port 4. The elastic valve core 2 and the pipe fitting 3 are arranged in the valve cylinder 1, the pipe fitting 3 is connected with the elastic valve core 2, and the side end of the valve cylinder 1 is provided with an air port 4 for introducing airflow.
[0016] The elastic valve core 2 is a rubber valve core.
[0017] A pneumatic connector 5 is installed at the air port 4.
[0018] Pipe fittings 3 are installed at the openings at both ends of the valve cylinder body 1, and both ends of the elastic valve core 2 are connected to the two pipe fittings 3 respectively.
[0019] A sealing ring is provided between the pipe fitting 3 and the opening of the valve cylinder 1 .
[0020] The working method of the present application is as follows: the fluid enters from the pipe fitting 3 at one end of the valve and flows out from the pipe fitting 3 at the other end through the elastic valve core 2. When the valve is to be closed, compressed air is only required to be sent into the valve cylinder 1 through the pneumatic connector 5 and the air port 4, and the air pressure in the valve cylinder 1 is used to squeeze the elastic valve core 2, so that the elastic valve core 2 will be squeezed and deformed, thereby blocking the flow of the fluid in the valve cylinder 1.
[0021] When the gas in the valve cylinder 1 is exhausted, the elastic valve core 2 will rebound to restore its shape, so that the fluid in the valve can return to fluid. The material of all mechanisms of the valve is non-metallic and the structure is simple, so it is corrosion-resistant and has a long service life.
