Mesolow, and suitable for high pressure.The closure principle of stop valve is, by valve stem pressure, makes valve clack sealing surface and valve base sealing
Face is brought into close contact, and prevents flow of media.Valve plays the important function of cut-out and throttling to the medium in the pipeline where it, cuts
Only valve blocks class valve as one kind is extremely important, and its sealing is to apply moment of torsion by valve rod, and valve rod is in the axial direction
Apply pressure to flap, valve clack sealing surface is brought into close contact with sealing surface of seat, prevent gap of the medium between sealing surface from letting out
Leakage.The sealing pair of stop valve is made up of valve clack sealing surface and sealing surface of seat, and valve rod drives flap to be hung down along the center line of valve seat
Straight motion.Height is opened in stop valve opening-closing process smaller, be easy to the regulation of flow, and manufacture easy to maintenance, the pressure scope of application
Extensively.
Existing some stop valves often occur the phenomenon for emitting water when in use, and this is close in bonnet due to stop valve
Envelope property is bad and cause, and in order to solve to emit water problems, the surface of stop valve is wound using adhesive tape often, very not
It is attractive in appearance, in order to solve these problems, we have proposed a kind of novel cutoff valve.
