The technological scheme that the utility model adopts is:
Flange 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, and the piston rod of cylinder and coupling yoke flexibly connect, and said coupling yoke and start and stop lever flexibly connect; Said start and stop lever is sleeved on the upper bearing plate of left valve barrel and right valve barrel, all is fixed with on the upper and lower support plate of upper bearing plate of left valve barrel and right valve barrel to be connected fixing device, and said start and stop lever suit is fixed on the valve plate; Also be fixed with the valve plate positioning means on the upper bearing plate of said left valve barrel, be provided with pressurized type valve plate sealing mechanism between said valve plate and the left and right valve body, said pressurized type valve plate sealing mechanism is a flange pressurized type sealing mechanism; Said flange pressurized type sealing mechanism comprises sealing flange, pressing plate and seal ring; Said valve plate both sides are provided with pressing plate, and said pressing plate is fixedly connected with sealing flange at two ends up and down, is fixed with seal ring between said pressing plate and the sealing flange; Said pressing plate middle part has sealed mouth; All have air-filled pore on the sealing flange of said valve plate both sides, said air-filled pore one end is connected with source of the gas, said air-filled pore the other end communication seals circle middle part.
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 air-filled pore on the left and right valve seal flange is inflated, annular seal space air pressure increased, and the seal ring elastic expansion compresses valve plate and forms sealing.When the need valve opening and closing seals, open the air-filled pore air venting on the sealing flange, the seal ring elastic recovery breaks away from valve plate, realizes the valve opening and closing sealing.
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.
