The technological scheme that the utility model adopts is:
Valve plate pressurising sealed type glasses valve comprises left valve barrel, right valve barrel, valve plate and cylinder, and said valve plate places between left valve barrel and the right valve barrel; Said cylinder is movably connected in the outside of right valve barrel; The piston rod of cylinder and coupling yoke flexibly connect, and said coupling yoke and start and stop lever flexibly connect, and said start and stop lever is sleeved on the upper bearing plate of left valve barrel and right valve barrel; All be fixed with on the upper and lower support plate of the upper bearing plate of left valve barrel and right valve barrel and be connected fixing device; Said start and stop lever suit is fixed on the valve plate, also is fixed with the valve plate positioning means on the upper bearing plate of said left valve barrel, is provided with valve plate pressurized type sealing mechanism between said valve plate and the left and right valve body; Said valve plate pressurized type sealing mechanism comprise the sealing plate that is separately fixed on the valve body of the left and right sides, be fixed in the seal ring and the pressing plate of valve plate both sides; Said pressing plate is located at the seal ring outside, and said pressing plate all is fixed on the valve plate both sides up and down, and said pressing plate middle part has sealed mouth; Said valve plate is provided with air-filled pore, and said air-filled pore one end is connected with source of the gas, and said air-filled pore two ends in addition is communicated with respectively in the middle part of the seal ring of valve plate both sides.
Said fixing device is a connecting rod, is fixed with a connecting rod on the upper bearing plate of said left valve barrel and right valve barrel, is fixed with two connecting rods on the lower support plate of said left valve barrel and right valve barrel.
Said valve plate positioning means comprises positioning cylinder, and positioning cylinder is provided with the positioning piston bar, is provided with positioning hole with the corresponding valve plate of positioning piston bar.
Said seal ring is the bowl seal circle that silicone rubber is processed.
The method for using of the utility model valve:
When valve was in the closure or openness sealing, through the air-filled pore on the valve plate is inflated, annular seal space air pressure increased expansion, and the sealing plate that seal ring compresses left and right valve body makes valve seal.When valve opening and closing commutated, the air-filled pore of opening on the valve plate made air venting, and seal ring is replied and broken away from sealing plate, realizes the valve opening and closing switching-over.
The beneficial effect of the utility model is: saved original locking and release arrangement, removed the corrugated stainless steel tubing connecting body, simplified production procedure, made cost of production reduce by 50%.That the utility model also has is simple in structure, driving force is little, sealing is reliable, and advantages such as sealing zero-abrasion and long service life.
