[0023] In this embodiment, the flow conversion mechanism 5 includes a discharge terminal 1 3, a control motor 4, an alloy valve core 6, a liquid feeding hole 8, a valve core membrane 9 and a discharge terminal 2 10. The discharge terminal 1 3 is arranged on one side of the valve body 1, and the other side of the valve body 1 is provided with a discharge terminal 2 10. The interior of the valve body 1 is provided with an alloy valve core 6, and a liquid feeding hole 8 is penetrated through the outer side of the alloy valve core 6. Valve core membranes 9 are arranged on both sides of the liquid feeding hole 8. A control motor 4 is arranged directly above the valve body 1, and the liquid is filtered through the valve core membrane 9 to prevent impurities in the liquid from clogging the alloy valve core 6.

[0024] In this embodiment, the valve body 1 is connected to the output shaft of the control motor 4 through the alloy valve core 6 disposed inside, and the liquid is injected and the inlet end is replaced by rotating the alloy valve core 6 .

[0025] In this embodiment, the sealing mechanism 14 includes an inner guide groove 11, a return spring 12, a sealing gasket 13, a guide rod 15 and an air pressure tube 16. The inner guide groove 11 is opened inside the alloy valve core 6. The sealing gasket 13 is arranged inside the inner guide groove 11. The top of the sealing gasket 13 is provided with a return spring 12. Both sides of the sealing gasket 13 are penetrated and connected with guide rods 15. The guide rods 15 are arranged inside the alloy valve core 6, and the two sides of the sealing gasket 13 are positioned and guided by the guide rods 15.

[0026] In this embodiment, the sealing gasket 13 is connected to the inside of the inner guide groove 11 through a reset spring 12 arranged at the top. The top of the sealing gasket 13 is vertically pulled by the reset spring 12 to facilitate the lifting and resetting of the sealing gasket 13.

[0029] Step 1: The operator first installs the pipelines at the discharge end 1 3, the discharge end 2 10 and the feed pipe 2 respectively. During use, the liquid is injected into the interior of the valve body 1, and the alloy valve core 6 is driven to rotate by the control motor 4, so as to open and reverse the interior of the valve body 1 by the alloy valve core 6, and the opening range of the liquid feeding through hole 8 is controlled by rotating the alloy valve core 6, and the liquid is injected and filtered through the valve core membranes 9 arranged on both sides;

[0030] Step 2: When the two liquids need to be injected, high-pressure gas can be injected into the inner guide groove 11 through the air pressure pipe 16 to vertically pressurize the sealing gasket 13. The return spring 12 will move vertically downward with the sealing gasket 13, and the inside of the liquid feeding through hole 8 will be blocked by the sealing gasket 13, thereby preventing the liquid from being retained in the liquid feeding through hole 8, and the residual liquid in the valve body 1 can be directly discharged through the drain valve 7;

[0032] Step 4: After the high-pressure gas is released, the operator can pull the top of the sealing gasket 13 through the return spring 12, and guide the two sides of the sealing gasket 13 through the guide rod 15 to affect the stability of liquid transportation. The residual liquid can be directly discharged through the drain valve 7 to avoid the liquid from being retained inside the valve body 1 and causing pollution to the liquid. The valve core membrane 9 is used to filter impurities in the liquid to avoid impurities being mixed in the liquid.

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
