Description
Technical field
The utility model belongs to pressure reducing valve field, and in particular to the pressure reducing valve with valve cover.
Background technology
Pressure reducing valve is by adjusting, inlet pressure being reduced to the outlet pressure of a certain needs, and by the energy of medium itself
Amount, makes outlet pressure automatically keep stable valve.From the viewpoint of hydrodynamics, pressure reducing valve, which is a local resistance, to be become
The restricting element of change makes the kinetic energy of flow velocity and fluid change, causes the different pressure losses that is, by change orifice size, from
And achieve the purpose that decompression.Then by the adjusting of control and regulating system, the fluctuation of downstream pressure is made to balance each other with spring force,
Downstream pressure is set to be kept constant in certain error range.It is managed after can reducing the higher fluid pressure of pipeline before valve to valve
Level needed for road.Here transmission medium is mainly water.Pressure reducing valve is widely used in skyscraper, city water-supply pipe network hydraulic pressure mistake
High region, mine and other occasions, to ensure respectively to obtain service hydraulic pressure and flow appropriate with water spot in water supply system.In view of
The leak rate of water and waste degree are almost directly proportional with the hydraulic pressure size of water supply system, therefore pressure reducing valve has improvement system operation
Operating mode and potential water saving effect, its water-saving result is about 30% according to statistics.Though flow has prodigious head loss by pressure reducing valve,
But due to reducing the waste of water and so that flow system flow is reasonably distributed, improve system layout and operating mode, generally speaking still
Be it is energy-efficient, but existing pressure reducing valve can not be mounted on high-pressure bottle mouth at directly as discharge valve, it is also necessary to it is external its
His pipeline and valve nozzle, it is also necessary to mouth and pipeline of the another setting for charging, it is complicated, it is of high cost, when there is no hypertonia
The protective device of time.
