Abstract
The utility model provides a novel water pump control valve which comprises a ring-shaped valve body, a seal ring, a big valve plate, a main shaft and a small valve plate. A water inlet end bypass port and a water outlet end bypass port are respectively arranged at two ends of the ring-shaped valve body. A groove is formed in the inner wall of the ring-shaped valve body, wherein the groove is arranged between the water inlet end bypass port and the water outlet end bypass port. The main shaft is deviated from the center of the ring-shaped valve body, and penetrates through the groove. One end of the main shaft is fixed on the inner wall of the ring-shaped valve body through a bearing. The other end of the main shaft penetrates through out of the ring-shaped valve body and is connected with a control mechanism. The big valve plate is supported on two round bosses which are fixed on the inner side of the ring-shaped valve body, and the big valve plate can rotate around the round bosses. The seal ring is installed on the outer side of the big valve body. A plurality of baffles are distributed on the inner side of the big valve plate. The big valve plate can enable one side, close to the water inlet end bypass port, of the groove to be sealed. The novel water pump control valve has the advantages that the structural size is short and small, a control pipeline is simple, a sealing effect is good when the novel water pump control valve is closed, and the phenomenon of a water hammer is not prone to occuring.
