Description
Technical field
The utility model relates to mechanical engineering valve technology field, relates in particular to a kind of valve with aerofoil profile self sealing structure.
Background technique
Valve is in fluid system, is used for controlling direction, the pressure of fluid, the device of flow.Valve is the device that medium (liquid, gas, powder) in pipe arrangement and equipment is flowed or stop and controlling its flow.
Valve is controlling component in pipeline fluid transporting system, and it is for changing path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.For the valve of fluid control, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are various, the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m to latus rectum from atomic little Gauge Valves.Valve can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and fluidly flows, the working pressure of valve can be from 0.0013MPa to 1000MPa ultrahigh pressure, operating temperature is from the high temperature of the ultralow temperature to 1430 of-270 ℃ ℃.The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, turbine, electromagnetic driven, electromagnetism surge, electricity surges, air-or liquid-operated, spur wheel, umbrella gear driving etc.; Can be under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, or do not rely on transducing signal and simply open or close, valve relies on driving or automechanism to make open-shut device do lifting, slippage, swing or rotation motion, thereby the size that changes its Flow area is to realize its control function.
Along with social development, not only easy for installation and firm and durable of research, and the valve of economic, energy-conservation and environmental protection, seem particularly important.The selfsealings mat structure adopting in the past, was all that graphite or O shape enclose to do sealing gasket, due to the High Temperature High Pressure in the situation that, all can not reach optimal sealing effect.
Model utility content
For above-mentioned defect of the prior art and problem, the utility model embodiment's object is to provide a kind of valve with aerofoil profile self sealing structure of better reliability, thereby improves steadiness.
In order to achieve the above object, the utility model embodiment provides following technological scheme:
With a valve for aerofoil profile self sealing structure, by valve body, valve seat, flashboard, restrictor bar, valve gap, gland, handwheel, seal ring and sealing configuration form, and it is characterized in that, and valve seat is arranged on below, valve body middle part, and flashboard top is connected with restrictor bar end,
Restrictor bar top is connected with valve gap top; Valve gap is arranged on outer end, valve body top, and gland is arranged on valve gap middle part top, and handwheel is arranged on valve gap top, and restrictor bar from center through gland and valve gap, flashboard from center through valve seat; Sealing configuration is between valve body and valve gap, and seal ring is separately positioned on the top at the two ends of sealing configuration and the Si Ge angle, upper and lower, left and right of valve seat.
As technique scheme preferably, described sealing configuration is divided into upper and lower 2 layers, centre is hollow, there is outside projection at horizontal two ends, are inserted with seal ring in projection.
As technique scheme preferably, seal ring is divided into U-shaped lip sealing ring and T font seal ring, wherein U-shaped lip sealing ring is arranged on the top at the Si Ge angle, upper and lower, left and right of valve seat, and each top is provided with laterally and 2 longitudinal U-shaped lip sealing rings, and T font seal ring is arranged in the two ends projection of sealing configuration.
The valve with aerofoil profile self sealing structure that the utility model embodiment provides, compared with prior art, advantage of the present utility model is just: in the time that medium enters valve inner, sealing configuration just and arrived the seal action of close-fitting, the pressure of valve is higher, and the sealability of valve is better, solve the high pressure sealing problem of current product.
