Description

Self-priming pump self-provided reflux valve

Technical Field

The invention relates to the technical field of self-sucking pumps, in particular to a self-provided reflux valve of a self-sucking pump.

Background

When the common self-priming pump is started, a period of original water injection circulation and gas-liquid separation process must be carried out, and a backflow hole in the pump is an original water injection circulation channel. The built-in backflow 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 cavity is in positive pressure, the water inlet cavity is in negative pressure, part of water in the water outlet cavity flows back to the water inlet cavity from the backflow hole under the action of pressure, and invalid diversion of the part of water directly reduces the operation efficiency of the pump. In order to solve the problem that a built-in backflow hole of a self-priming pump is still smoothly shunted after self-priming, the backflow valve is arranged in the backflow hole in the industry, which is an effective technical measure.

At present, the return valves used in engineering mainly have two typical structures, one is a return valve of a manual ball valve structure, and the other is a return valve of a floating stop valve structure. The former backflow valve has simple structure, tight closing and free opening and closing, but the self-priming pump is manually opened when being started every time, and is manually closed after self-priming is realized. The return valve of the stop valve structure can be automatically opened and closed along with the pressure difference between the water outlet cavity and the water inlet cavity when the self-sucking pump operates, and the valve core of the return valve is made of a rubber material with resilience force so as to meet the requirement of moving along with the pressure. The traditional rubber material is easy to age, the manufacturing process is complex, the reliability is not high, and the problem of internal leakage is easy to occur after aging. Therefore, we improve the self-priming pump and provide a self-contained reflux valve.
