Description
Technical field
The utility model relates to mechanical engineering valve technology field, particularly relates to a kind of eccentric V-arrangement ball valve.
Background technique
Valve is in fluid system, is used for controlling the device of the direction of fluid, pressure, flow.Valve is the device medium in pipe arrangement and equipment (liquid, gas, powder) being flowed or stops also controlling its flow.
Valve is controlling component in pipeline fluid transporting system, and it is used to change 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 that fluid controls, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification 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 ultrahigh pressure from 0.0013MPa to 1000MPa, and operating temperature is from the ultralow temperature of-270 DEG C to the high temperature of 1430 DEG C.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 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 rely on drive or automechanism makes open-shut device be elevated, slippage, swing or rotation motion, thus the size changing its Flow area is to realize its controlling functions.
Along with the development of society, along with the develop rapidly of the industries such as Modern Large tool, oil, chemical industry, new energy, nuclear industry, the sealing reliability of valve requires more and more high, the V-arrangement ball valve used in oil, chemical industry operating mode at present, because catalyzer, cinder, the media such as pitch usually occur making sealing surface gum deposit, cause ball valve stuck, valve rod such as to twist off at the phenomenon, and using effect is very undesirable.
Model utility content
For above-mentioned defect of the prior art and problem, the object of the utility model embodiment is to provide a kind of eccentric V-arrangement ball valve of better reliability, thus increases work efficiency.
In order to achieve the above object, the utility model embodiment provides following technological scheme:
A kind of eccentric V-arrangement ball valve, it is characterized in that, by lower valve rod, valve body, insulation jacket, floating valve seat assembly parts, high-temperature steam annular jet, hemisphere, high-temperature steam import, high-temperature steam outlet, straight pin, upper valve rod, support, actuator is driven to form, lower valve rod is arranged on valve inner bottom, hemisphere is arranged on valve body, and hemisphere is provided with V-notch, valve body is outside equipped with insulation jacket, the valve inlet chamber place of valve body is provided with high-temperature steam annular jet, valve body surface is also provided with high-temperature steam import and outlet, floating valve seat assembly parts is positioned at above insulation jacket, be arranged at hemisphere side, and high-temperature steam annular jet, floating valve seat assembly parts and insulation jacket are provided with through hole, valve body, hemisphere is positioned by lower valve rod, upper valve rod taper pin is fixed, upper valve rod top is connected with driving actuator, bottom is connected with hemisphere, actuator is driven to be connected with support.
Preferred as technique scheme, described hemispheroidal spindle central is not concentric with upper and lower valve rod.
Preferred as technique scheme, described floating valve seat assembly parts is close in hemispheroidal side seal cambered surface by spring sealed.
The eccentric V-arrangement ball valve of the one that the utility model embodiment provides, compared with prior art, advantage of the present utility model is just: structure is simple, easy to use, hemisphere is provided with V-notch, between V-notch and metal seat valve, there is shear action, the residue scraped on floating valve seat sealing surface can be cut, floating valve seat sealing surface is made to keep bright and clean, be particularly suitable for fibre-bearing, minute solid particles, the media such as slip, hemispheroidal gyration center is not concentric with rotating shaft, the whole process opened and closed, external force just departs from instantaneously in keying or compresses, reduce the prooving of valve seat, and valve rod only needs half-twist, valve rod moment of torsion is little, convenient to operation, namely just can close tightly with very little moment of torsion, increase the service life, floating valve seat assembly parts makes valve base sealing be close on spool hemisphere sealing surface under spring and entrance medium thrust, that sealability is reliable, high-temperature steam annular jet and thermal insulation clamp mantle cavity through, one deck barrier is formed when high-temperature steam enters between entrance point and medium, thus prevent from producing gum deposit between V-arrangement ball and the contact surface of valve seat.
