T-piece splitting valve is in material-transporting system, to control the material ideal equipment of commutation fast, extensively with carrying for the industry solid particles such as building materials, metallurgy, mine, light industry, grain and powdered materials.Existing T-piece splitting valve, the actuator that includes valve body, valve shaft, valve plate and drive valve shaft to rotate, valve body has supply pipe, the first discharge port and the second discharge port, sealing while closing for improving valve plate, on valve plate, install flexible rubber plate additional, rubber gasket sheet is pressed on valve interior wall and realizes and sealing.Valve plate is in the moment of closing sealing, due to the inertial force effect of valve plate, flexible rubber plate and valve body cavity inner wall have certain shearing force, because flexible rubber plate roughness is large, large with valve body cavity inner wall frictional force, in the time constantly switching, flexible rubber plate wear extent is large, causes the working life of valve plate short; And adopt merely metal valve plate, and being pressed on valve interior wall at valve plate, metal valve plate directly impinges upon on valve body, easily damages valve plate and valve body, and sealing is poor.
Summary of the invention
The deficiency existing for prior art, the inertial force that provides a kind of available buffer valve plate to close is provided the purpose of this utility model, valve plate seals the T-piece splitting valve of reliable and long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of T-piece splitting valve, include with supply pipe, the valve body of two discharge ports, in valve body, be provided with valve shaft and valve plate, described valve plate includes two metal mounting plates, two metal mounting plate one end are fixed on valve shaft, between the two metal mounting plate the other ends, be provided with black box through lock bolt locking clamp, on valve shaft, be connected with actuator, it is characterized in that: described black box includes metal sealing plate, flexible rubber plate and supported spring, described flexible rubber plate both sides are the folded metal sealing plate that is provided with all, between described flexible rubber plate and metal sealing plate, be provided with metal sealing plate is pressed on to the supported spring on corresponding metal mounting plate.
By adopting technique scheme, flexible rubber plate is established through two metal sealing plate holders, in the time of sealing, first metal sealing plate contacts with valve interior wall, shear material, and metal sealing plate supports through supported spring, form float support, the inertial force that supported spring can effectively absorb valve plate while closing, slow down the shock of metal sealing plate and valve body, effectively improve the working life of valve plate, and valve plate is closed while putting in place, there is twice metal sealing layer and one deck rubber sealant, guarantee sealing reliability.
The utility model is further set to: the seal face of described flexible rubber plate and two metal sealing plates is spherical crown surface, and two metal sealing plates are positioned at sealed end and are extended with protruding prolonging towards flexible rubber plate one side, described flexible rubber plate is positioned at sealed end both sides and is provided with the protruding embedding short slot that prolongs for two metal sealing plates.
By adopting technique scheme, spherical crown surface shearing force is large, good airproof performance, and two sheet metal epireliefs prolong with the short slot on flexible rubber plate and coordinate, formation motion guide, and the sealing metal plate being more preferably is connected with the spherical crown surface of flexible rubber plate.
The utility model is further set to: described supported spring is volute spring.
By adopting technique scheme, volute spring has better support effect, is convenient to compression.
This practicality is newly further set to: described actuator includes cylinder, push rod and connecting rod, described push rod is connected with described valve shaft by described connecting rod, the outside of described valve body is fixed by the cylinder block end of connection bracket and described actuator, and described cylinder block is hinged in connection bracket.
By adopting technique scheme, adopt air cylinder driven push rod, connecting rod and valve shaft control valve plate, have advantages of that control rate is fast.
The utility model is further set to: the supply pipe on described valve body and two discharge ports are circular ports, and described supply pipe and two discharge ports are provided with circular flange dish.
By adopting technique scheme, valve body can directly be connected with pipeline, easy to connect, and flange plate connection, easy to connect reliable.
Below in conjunction with accompanying drawing, the utility model is further described.
