Description

A kind of pressure-reducing valve
Technical field
The utility model is related to valve field, and in particular to one kind decompression water valve.
Background technology
Pressure-reducing valve is, by regulation, inlet pressure to be reduced to the outlet pressure of a certain needs, and the energy by medium in itself Amount, makes outlet pressure keep the valve of stabilization automatically.From the viewpoint of hydrodynamics, pressure-reducing valve is that a local resistance can become The restricting element of change, i.e., by changing orifice size, change the kinetic energy of flow velocity and fluid, causes the different pressure losses, from And reach the purpose of decompression.Then by control and the regulation of regulating system, the fluctuation and spring force for making downstream pressure balance each other, Downstream pressure is set to keep constant in certain error range, the pressure-reducing valve used on current household water pipe uses rubber film Piece, it is easy to aging, short life, when hydraulic pressure is too high and water hammer, water temperature change greatly, causes sometimes cold and sometimes hot during bathing, is shadow Ring pot-type boiler, water purifier, water pipe and booster, the main reason of leak occur, easily cause the destruction to water equipment, cause Economic loss.
The content of the invention
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of profile is succinct, structure is simple Single reliable, easy for installation, long lifespan pressure-reducing valve, it controls water flow pressure with by pressure adjustment knob, while on pressure gauge 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 Power adjusting knob controls water flow pressure, is not in let out while interface is provided with packing ring on pressure gauge, it is ensured that intact sealing Leakage phenomenon.
