The first pump head 12 has a first water inlet end 121 and a first water outlet end 122. The second pump head 13 has a second water inlet end 131 and a second water outlet end 132;

The first water inlet channel 2 and the first water outlet channel 3, the first water inlet channel 2 is connected to the first water inlet end 121, and the first water outlet channel 3 is connected to the first water outlet end 122;

The second water inlet channel 4 and the second water outlet channel 5, the second water inlet channel 4 communicates with the second water inlet end 131, and the second water outlet channel 5 communicates with the second water outlet end 132; and,

The control valve 6 is provided on at least one of the first water inlet channel 2 , the first water outlet channel 3 , the second water inlet channel 4 and the second water outlet channel 5 .

In this embodiment, the diaphragm pump is also called a pneumatic diaphragm pump or a pneumatic double diaphragm pump. Diaphragm pump is a kind of reciprocating pump. It uses elastic film, corrosion-resistant rubber or elastic metal sheet to separate the pump head into two parts that are not connected to each other, which are used as the area where the liquid to be transported and the live column exist, so that the live column does not interact with each other. Contact with the liquid being transported. The reciprocating motion of the movable column is transmitted to the diaphragm through the medium on the same side, so that the diaphragm also reciprocates, so as to realize the suction and discharge of the conveyed liquid through the spherical valve. The double-headed diaphragm pump 1 is a diaphragm pump installed at both ends of a coaxial motor, and the two diaphragm pumps are driven by the same motor to work. The double-head diaphragm pump 1 can control the water volume, has a large compression ratio, and has good sealing performance.
