Description

Technical Field

[0001] The utility model relates to the technical field of switch valves, in particular to a damage-proof switch valve for a pump. Background Art

[0002] In order to control the water flow in the water pipe, a switch valve is usually installed on the water pump, which can not only turn on and off the water flow, but also adjust the size of the water flow. A general water valve includes a valve seat, a valve stem and a valve core. The valve core is rotatably set on the valve seat, and the valve stem drives the valve core to rotate. A water flow channel is provided on the valve seat, and a through hole is provided on the valve core. When the valve core rotates to the through hole and the water flow channel are connected, the valve is opened; when the valve core rotates to the through hole and the water flow channel are blocked, the valve is closed. The valve core is used to control the on and off of the water flow channel. Because the switch valve is always at the outer end of the water pump, the switch valve needs to be protected to avoid damage from external factors.

[0003] The prior art patent document with publication number CN219509811U discloses a pump body structure for preventing the switch valve from being damaged, comprising a pump body, a pump chamber, a liquid inlet, a liquid outlet, a filtering mechanism and an anti-collision spring, wherein the anti-collision spring is arranged at the liquid outlet; a slag discharge channel is arranged at the connection between the pump chamber and the liquid inlet, the head end of the slag discharge channel is communicated with the liquid inlet, the middle part of the slag discharge channel is communicated with the pump chamber, a filtering mechanism is arranged in the slag discharge channel, the filtering mechanism comprises a filter nut, a first filter and a second filter, the filter nut is arranged at the tail end of the slag discharge channel, the first filter is cylindrically fitted on the inner side of the slag discharge channel, and the wide-mouth end of the funnel-shaped second filter fitted with the first filter is placed on the head end side of the slag discharge channel. In the present application, the structure is simple, the design is reasonable, the manufacturing difficulty is small, and the cost is reduced; the filtering mechanism of the two-layer filter structure arranged in the pump body greatly enhances the effect of filtering impurities, which is conducive to the stable operation of the pump body; the wear of the inner wall of the pump body by the liquid flow and impurities is reduced by the anti-collision spring to increase the service life.

[0004] However, in the prior art CN219509811U patent, the switch valve is always installed at the outer end of the pump body. If it is exposed to the outside for a long time, it will be damaged by external factors. The prior art has poor protection for the switch valve, and the switch valve may be hit and collided, shortening the service life of the switch valve. Utility Model Content
