[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0018] See attached Figure 1-7 A diaphragm valve for industrial washing machine dispenser, comprising a valve body 9, a valve core water cavity 6 is arranged at the center of the valve body 9, an outer ring water cavity 8 is arranged at the outer edge of the valve core water cavity 6, a water inlet pipe port Ⅰ1, a pipe port Ⅱ2, a laundry liquid inlet 4, a gas inlet 7, and a diaphragm valve outlet 5 are arranged on the periphery of the valve body 9, and the pipe port Ⅰ1, the pipe port Ⅱ2 are connected with the outer ring water cavity 8 and the laundry liquid inlet 4 (such as Figure 6 ), the valve core water cavity 6, the gas inlet 7 and the diaphragm valve outlet 5 are interconnected, and the laundry liquid inlet 4 and the gas inlet 7 are both provided with a one-way valve; the valve body 9 is provided with a diaphragm connection hole 10, the valve body 9 is fixedly connected to the diaphragm 11 through the diaphragm connection hole 10, the diaphragm 11 is connected to the cylinder push rod 12, the valve body 9 is fixedly connected to the cylinder 3 through screws, and the diaphragm 11 is pressed. Multiple diaphragm valves can be connected to each other, the pipeline port II2 of one diaphragm valve is connected to the pipeline port I1 of another diaphragm valve, and the connection is sealed and fixed with a sealing ring and a clamp, and so on, and can be set according to actual needs.

[0019] The laundry liquid inlet 4 and the gas inlet 7 are both equipped with a one-way valve, and the laundry liquid, water and gas can only flow out from the diaphragm valve outlet 5. When the industrial washing machine needs laundry liquid, the cylinder 3 is activated to open the diaphragm valve diaphragm 11 (such as Figure 5 ), the laundry detergent is pumped into the corresponding amount from the laundry detergent inlet 4 with a pump, and the laundry detergent enters the valve core water cavity 6 from the outer ring water cavity 8 of the diaphragm valve, and then water enters from the pipeline port Ⅰ1 and the pipeline port Ⅱ2. Since the pipeline port Ⅰ1, the pipeline port Ⅱ2, the outer ring water cavity 8 and the laundry detergent inlet 4 are interconnected, they will flow to the diaphragm valve outlet 5. After adding water for a certain period of time, the diaphragm valve is closed, and then compressed air is pumped in from the gas inlet 7 to flush the compressed air for a certain period of time.

[0020] The purpose of opening the diaphragm valve is to allow the laundry detergent to be distributed into the water cavity of the opened diaphragm valve core, flow into the corresponding industrial washing machine, and then flush the pipeline with water.

[0021] The purpose of flushing compressed air is to make the pipeline clean and free of a mixture of detergent and water.

[0022] Figure 7This is a rendering of a combination of multiple diaphragm valves. The multiple diaphragm valves are connected to each other, and the connections are fixed and sealed with clamps and sealing rings. For example, there are 8 kinds of detergents, corresponding to 9 washing machines. When one of the washing machines needs one of the detergents A, the electrical control system starts, closes the diaphragm valves of other dispensers, opens the diaphragm valve of the required detergent dispenser, and dispenses detergent A into the water cavity of the opened diaphragm valve core and flows into the corresponding industrial washing machine. The pipeline is then flushed with water and compressed air. The 8 detergents can be switched at any time according to the needs of the system settings. After each addition of detergent, flushing with water and compressed air ensures that the pipeline is clean and there is no mixture of laundry detergent and water.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
