Interface is provided with packing ring, it is ensured that intact sealing, is not in leakage phenomenon.
In order to solve the problems existing in background technology, the utility model is to use following technical scheme：A kind of pressure-reducing valve,
It includes valve body；Described valve body upper end beveled end is provided with connection end；Described connection end connection pressure gauge；Described valve body
Upper end be fixed with bonnet；Pressure adjustment knob is provided with described bonnet；The left and right two ends of the valve body are respectively water inlet
End and water side, and direction is consistent in level；Spring, lower spring, valve element one and valve element two are provided with described valve body；Institute
The upper and lower ends for stating spring are separately positioned between bonnet inner side and valve element one；The upper and lower ends difference of described lower spring
It is arranged on the bottom of valve element two and the inner side of valve body；Connector is provided between described valve element one and valve element two
Preferably, described water inlet end and water side inner side are provided with screen pack；The water inlet end, water side and outside
Water pipe is connected.
Preferably, described valve body uses copper valve body.
Preferably, described pressure adjustment knob is interior hexagonal knob.
Preferably, interface is provided with packing ring on described pressure gauge.
When the utility model is operated, pressure-reducing valve is horizontally installed on water pipe according to water (flow) direction, and pressure gauge rotates on valve body
At inclination on connectivity port, measured value and water flow pressure situation on observation pressure gauge, by die nut regulating valve bonnet internal pressure
Power adjusting knob, is turned clockwise so that upper spring compresses to the direction of valve element one, and band movable valve plug one is moved down, and reduces water outlet
Pressure；Rotate counterclockwise so that upper spring is moved to bonnet direction, band movable valve plug one is moved up, and increases discharge pressure；Valve body
It is durable in use with explosion-proof using copper valve body；Interface is provided with packing ring on pressure gauge, with sealing reliability, prevents
Current overflow, the damage of build-up of pressure table, increase service life.
The utility model beneficial effect：Its profile is succinct, simple and reliable for structure, easy for installation, long lifespan, its use are by pressure
