Mechanical water leakage protector with pressure-reducing and non-return functions and application method thereof

Abstract

The invention discloses a mechanical water leakage protector with pressure-reducing and non-return functions and an application method thereof. The mechanical water leakage protector with the pressure-reducing and non-return functions comprises a valve body, an inlet end and an outlet end are arranged on the valve body, and a pressure reducing valve is installed at the inlet end. A non-return valve is installed at the outlet end. The mechanical water leakage protector with the pressure-reducing and non-return functions is characterized in that a safety valve installation opening is further formed in the valve body, and a safety valve is installed on the safety valve installation opening; and the safety valve comprises a fixing frame, a base and a rubber diaphragm. Through the safety valve,a flow path is automatically cut off according to the increase of the water-leakage water level in the case of water leakage in a water purifier, and the situation that water is leaked to a floor dueto continued water leakage is avoided. Through the pressure reducing valve, the inflow water always maintains the set water pressure to avoid damage to internal components and parts of the water purifier due to excessive water pressure, and the service life of the water purifier is prolonged; and the non-return valve is arranged at the outlet end, and the situation that secondary pollution of thewater source is caused due to the fact that water in the water purifier returns to a waterway outside the water purifier caused by insufficient water pressure is avoided.

Description

technical field [0001] The invention relates to a water leakage protector, in particular to a mechanical water leakage protector with decompression and backstop functions and a use method. Background technique [0002] At present, during the long-term use of the water purifier, the water leakage of the water purifier usually occurs, which affects the normal use and life. Therefore, many existing water purifiers have added water leakage protectors, but these water leakage protectors Can only be used once, cannot be reused, short life, high cost, troublesome disassembly; [0003] As the announcement number is CN207333727U disclosed in a leakage protection valve, the base is provided with an expansion chamber and a push plate, and the expansion chamber is provided with an expansion body; At a certain height, the water on the ground overflows into the water leakage protector placed on the ground through the water leakage protection valve leakage inlet.

[0002] At present, during the long-term use of the water purifier, the water leakage of the water purifier usually occurs, which affects the normal use and life. Therefore, many existing water purifiers have added water leakage protectors, but these water leakage protectors Can only be used once, cannot be reused, short life, high cost, troublesome disassembly;

[0003] As the announcement number is CN207333727U disclosed in a leakage protection valve, the base is provided with an expansion chamber and a push plate, and the expansion chamber is provided with an expansion body; At a certain height, the water on the ground overflows into the water leakage protector placed on the ground through the water leakage protection valve leakage inlet. A seal conflicts with the control port in the main body to achieve the purpose of disconnecting the waterway; the expansion body absorbs water and expands to push the slider to move upwards, and this method can only be used once, and the expansion body needs to be replaced after one time , installation is troublesome and costly
