Pressure component is made up of stream cover, valve element and valve seat, and the valve element is arranged on the central authorities of reducing pressure by regulating flow component, and the valve seat is arranged on
The lower section of valve element, the lower left of the reducing pressure by regulating flow component are provided with input duct, and the right side of the reducing pressure by regulating flow component is arranged
There is drain pipe road, valve rod is installed directly over the valve element, the top of the valve body is fixed with valve gap, the valve element and valve gap
Between connection fixed by snap, be provided with sealing ring between the valve rod and valve gap, the both sides top of the valve gap is provided with
Bolt, the screw bolt passes pad and valve gap are connected with valve body.
The left side and right side of the valve body is respectively arranged with inlet and liquid outlet.
The top of the valve rod is fixed with handwheel.
Connected by input duct between the inlet and reducing pressure by regulating flow component.
Connected by drain pipe road between the liquid outlet and reducing pressure by regulating flow component.
Compared with prior art, the beneficial effects of the utility model are：The equipment can realize multistage section by stream cover
Stream blood pressure lowering so that valve inner pressure to balance, and effectively prevent the generation of cavitation phenomenons, extend valve element and use the longevity
Life, is provided with sealing ring between valve gap and valve rod, not only acts as the function of sealing, and can to positioning to valve element,
Reduce vibration and the appearance of noise occur, valve gap is with valve design into separate type so that stop valve maintenance easy to disassemble.
