Description
Technical field
The utility model relates to mechanical engineering valve technology field, particularly relates to a kind of high temperature super abrasive anti-coking flap type.
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, and Bellows valve has zero leakage, there is wide market, a large amount of use will be obtained.
Study not only easy for installation and firm and durable, and economy, energy saving standard valve, seem particularly important.In prior art, the complex dielectrics such as coal chemical industry enterprises coal slurry, catalysis device coal slurry, catalyzer make have received great test the working life of valve.Seal ball-valve of the prior art half-open partly close time, the badness-media such as coal slurry, catalyzer can enter valve body and is full of valve pocket thus makes valve cannot normal switch, and this valve is in half-open half off status, the solid particles such as catalyzer wash away, wear and tear this valve sealing surface, seal leakage when making valve in off position, brings massive losses to enterprise.
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 high temperature super abrasive anti-coking flap type 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 high temperature super abrasive anti-coking flap type, comprises flashboard, protective housing and valve seat, it is characterized in that, in valve body epicoele, valve switch is outside equipped with protective housing, is connected between valve seat with protective housing with bolt, valve seat is equipped with spring, be filled with graphite between spring and valve seat, flashboard adopts parallel Single disc structure, vertically inserts in valve body cavity of resorption, flashboard top is connected with stem bottom, semicircular in shape bottom flashboard, and flashboard is provided with large aperture circular hole, circular hole and valve body cavity of resorption through.
Preferred as technique scheme, the sealing surface corner of described flashboard and valve seat contacting point is all processed as acute angle.
Preferred as technique scheme, described gate panel surface adopts surfacing to be coated with Ni60B material, i.e. high nickel-base material.
Preferred as technique scheme, described protective housing is provided with perforation, and lower end is half round concave shape arc limit, and two ends, left and right are provided with the bound edge be connected with valve seat, are provided with perforation nut in bound edge.
Preferred as technique scheme, the thickness of described flashboard is more than or equal to 2mm.
A kind of high temperature super abrasive anti-coking flap type that the utility model embodiment provides, compared with prior art, advantage of the present utility model is just: elegant in shape, switch flexibly, the feature such as long service life, there is the specific function of super abrasive, corrosion-resistant, resistance to oxidation, removal of contamination, shearing impurity simultaneously, be applicable to very much coal chemical industry enterprises and produce catalyzer, the badness-medias such as coal slurry.Valve seat is equipped with spring, and spring has decrement can make valve seat and flashboard close contact, makes valve sealing face have larger integrated abrasion compensation.Valve seat is connected with protective housing bolt, can prevent valve coal slurry, catalyzer in the process opened and closed from entering valve gap epicoele and valve inner, keep the clean clean of valve pocket, ensure that valve can open and close smoothly, improve working life.
