The purpose of this utility model is to provide a kind of Pump Failure switch, to solve proposed in the above background technology ask Topic.

To achieve the above object, the utility model provides following technical solution：A kind of Pump Failure switch, including valve body, Waterpipe jointing, water pump, cut-off switch；The valve body is cylinder, and inside upper part centre position is equipped with cavity, and the cavity is Pressure cavity；The upper top of the pressure cavity is equipped with check valve；The centre position of the check valve is piston；It is described Water pump is located at the valve body top surface side, and is communicated with valve inner pressure cavity；The waterpipe jointing is arranged on the valve body Top surface opposite side, the pressure cavity are communicated by check valve with waterpipe jointing；Close to the water pipe on the upside of the valve inner The position of interface is equipped with control chamber, and cut-off switch is installed on inside the control chamber；One end of the cut-off switch is connected with pressure Power button.

Preferably, it is equipped with briquetting on the downside of the middle position of the piston；Piston and valve are provided through in the middle part of the briquetting The bolt that body is connected.

Preferably, it is cased with water pipe on the outside of the waterpipe jointing；The other end of the water pipe is connected with tap.

Preferably, both sides are arranged with fixed plate on the outside of the middle part of the valve body；The centre of the fixed plate is equipped with installation Notch；Side connection tubular switch cover of the control chamber away from pressure-button.

Preferably, adapter cavity is formed between the waterpipe jointing and the piston；Pressed for pressure the side of the adapter cavity Button；The pressure-button is closed type rubber Self-resetting button.

Compared with prior art, the beneficial effects of the utility model are：The utility model can carry out pressure guarantor to water pump Shield, extends the service life of water pump；Water pump is internally provided with built-in check valve, reduces the exterior check valve being directly connected with water pump Use, prevent water pump flow out water reflux, ensure pressure switch will not receive water pump reflux influence；The water that water pump pumps out passes through Valve body, into pressure cavity, is equipped with check valve, current enter waterpipe jointing, waterpipe jointing by check valve at the top of pressure cavity Tap is connected by water pipe, cut-off switch is connected with pump circuit, and when tap is opened, water pump is opened and outwards pumped, Pressure cavity and adapter cavity internal pressure are smaller, and cut-off switch will not work, when the faucet is turned off, when water pump is initial still in Opening, pressure cavity and adapter cavity meeting ponding, and pressure rises, when the pressure of adapter cavity reaches certain limit, pressure Power button is pressed, cut-off switch work, Pump Failure；When tap reopens, transition cavity pressure diminishes, pressure-button bullet Open, cut-off switch is stopped, water pump be powered, it is thus achieved that with cut-off switch when water pump occur pressure it is excessive when cut-off switch Switch off the pump, water pump is stopped, when tap reopens, cut-off switch reopens water pump, and water pump was carried out Pressure protection.
