A flap is provided with the bonnet baffle and adjusts installation cavity, guide sleeve, the valve are provided with the flap regulation installation cavity
Valve is connected with operating valve lever, and the operating valve lever is sheathed in the guide sleeve, and the end of the operating valve lever connects one and prolonged
Long adjusting rod, the bonnet baffle center are provided with the through hole that can wear the extension adjusting rod, the extension adjusting rod
Termination is provided with screw rod, and the screw rod is provided with the fixation stop nut that can adjust the flap stroke, the spacing spiral shell of fixation
Female end face is positioned with the end contact in the bonnet baffle, and the bonnet baffle end face inside the valve body cavity is set
There is locating flange step, stainless steel compression spring is provided between the flap and the locating flange step.
The flap is provided with the sealing gasket for being capable of noise reduction towards fluid input face, and the sealing gasket is ethylene propylene diene rubber
Pad.
The flap is raised towards the circular arc that can reduce fluid impact is additionally provided with fluid input face.
The flap and operating valve lever are process by the steel-casting of integrally casting.
The fixed stop nut is two or more；Can effectively it loosen.
The beneficial effects of the utility model are：
1st, passed through in the guide sleeve that the operating valve lever set on flap can be adjusted in installation cavity from flap, with operating valve lever
The extension adjusting rod of connection is extended on the outside of bonnet baffle, can utilize the screw rod extended on adjusting rod and fixed stop nut
The keying stroke of flap is adjusted, can be adjusted according to different medium and applying working condition, non-return effect is more preferable；
2nd, flap is capable of the sealing gasket of noise reduction towards setting on fluid input face and reduces the circular arc projection of fluid impact,
Flap can be effectively reduced in non-return motion and hits sound, muting function is good after long-term use；
3rd, succinct reliable, the service life length of valve flap structure.
