Abstract

The invention discloses a self-contained return valve of a self-priming pump. The self-contained reflux valve comprises a base, a driving motor, a pump body and an air extractor are sequentially and fixedly installed at the top end of the base from one side to the other side, an installation plate is arranged at the bottom end of the driving motor and the bottom end of the pump body, a transmission shaft is arranged at one end of the driving motor, and a signal box is installed at the top end of the driving motor. According to the self-contained return valve of the self-priming pump, a wireless module is arranged to facilitate signal connection with a cloud server, so that the device can be remotely controlled and used through the Internet of Things, the air extractor, a return cavity, a plug ball and a self-priming channel are arranged to assist in guiding and conveying liquid to the pump body, an excellent hydraulic model is adopted, the efficiency is higher than that of a common self-priming pump, the self-priming performance is good, the self-priming height is higher than that of a common self-priming pump, and the self-priming time is shorter; and the air extractor and the return cavity are arranged to assist in guiding the liquid to the pump body, the efficiency is higher than that of the common self-priming pump, the self-priming performance is good, the self-priming height is higher than that of the common self-priming pump, and the self-priming time is shorter.

Description

technical field [0001] The invention relates to the technical field of self-priming pumps, in particular to a self-priming pump self-contained return valve. Background technique [0002] Ordinary self-priming pumps must go through a period of original water injection cycle and gas-liquid separation process when starting, and the return hole in the pump is the original water injection cycle channel. The built-in return hole of the self-priming pump in the prior art is a through hole. When the self-priming pump realizes self-priming, the water outlet chamber is under positive pressure, the water inlet chamber is under negative pressure, and part of the water in the water outlet chamber flows back from the return hole under the action of pressure. The water inlet chamber, this part of the water is effectively shunted and directly reduces the operating efficiency of the pump. In order to solve the problem that the built-in backflow hole of the self-priming pump is still unblock...
