Semispherical valve is an a kind of novel valve closing door fast, it is a kind of without hindrance flowing valve, be mainly used in the switch control rule valve that the dry ash in the field air-transport systems such as electric power, metallurgy, chemical industry, food, pharmacy, the material feeding mouth of dry material, discharge port, relief opening and pipeline switch, semispherical valve is in the market used for the industries such as electric power, metallurgy, chemical industry, for the sterile closed environment of pharmaceutical industry, traditional semispherical valve cannot reach this demand aseptic, and majority can not bear vapor pressure when steam sterilizing, reaches airtight.
Existing semispherical valve top spool adopts semi-circular air-tight structure to seal, and when dome valve is in closed condition, seal ring can not well contact with sphere core, thus can not play good sealing effect.
Model utility content:
The purpose of this utility model is to provide a kind of pneumatic actuator semispherical valve, its structure is simple, reasonable in design and easy to use, the sealing of spool place, top adopts integral ring-shaped hermetic seal, when dome valve is in closed condition, rubber seal expands by inflating, thus is tightly wrapped on sphere core, forms a seal band very reliably, its sealing is tight, effectively can block the flowing of material in pipeline.
In order to solve the problem existing for background technique, the utility model is by the following technical solutions: it comprises valve body, bearing cap gasket seal, clutch shaft bearing lid, stainless steel bearing, first coupling shaft, connecting bushing, swinging driver, valve body pad, valve flange, airtight packing, second coupling shaft, second bearing cap, O RunddichtringO, spool and poppet shaft attachment spacers, the upper end of valve body is provided with valve flange, the internal connection of valve body and valve flange is provided with several airtight packing, the external connections of valve body and valve flange is provided with valve body pad, the inside center of valve body is provided with spool, the left end of spool is provided with the second coupling shaft, the joint of the second coupling shaft and valve body is provided with several O RunddichtringO, the left end of the second coupling shaft is provided with the second bearing cap, the joint of the second bearing cap and valve body is provided with poppet shaft attachment spacers, the central right inside of valve body is provided with the first coupling shaft, the left side outer race of the first coupling shaft is connected to stainless steel bearing, the outer race of stainless steel bearing is connected to clutch shaft bearing lid, the joint of clutch shaft bearing lid and valve body is provided with bearing cap gasket seal, the right side of clutch shaft bearing lid is provided with connecting bushing, the right-hand member of the first coupling shaft is provided with swinging driver.
Utility model works principle: semispherical valve in use, drives the first coupling shaft to rotate by swinging driver, and the first coupling shaft in rotation can drive the spool of valve inner to rotate, thus the dress of the sealing and unlatching that realize semispherical valve changes.
The utility model has following beneficial effect: its structure is simple, reasonable in design and easy to use, the sealing of spool place, top adopts integral ring-shaped hermetic seal, when dome valve is in closed condition, rubber seal expands by inflating, thus be tightly wrapped on sphere core, form a seal band very reliably, its sealing is tight, effectively can block the flowing of material in pipeline.
Accompanying drawing illustrates:
