Description
Technical field
The utility model relates to a kind of abrasion resistant type high pressure valve.
Background technique
High pressure valve has been widely used in superhard material manufacture, chemical industry, petrochemical industry, processing technique, isostatic pressed process, ultra-high static pressure extruding, powder metallurgy, metal forming and the field such as geophysics, geology pharmacological research.Can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Open-shut device is a discoidal valve plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.
Superhigh pressure technique has been widely used in superhard material manufacture, chemical industry, petrochemical industry, processing technique, isostatic pressed process, ultra-high static pressure extruding, powder metallurgy, metal forming and the field such as geophysics, geology pharmacological research.Can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Open-shut device is a discoidal valve plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.On pipeline, main rising is cut off and throttling action.Due to widely using of high pressure technique, the Super high pressure valve performance in extra high voltage system directly affects the reliability of whole system work, Security, working efficiency and working life.In the system of the frequent supercharging release of those palpuses, seem particularly important.The dominant failure reason of Super high pressure valve is, cavitation erosion and erosive wear, and the factor of impact cavitation erosion and erosion is a lot, mainly contains the mechanical property of material, hydrodynamic factor and environmetal impact.Improve the ability of valve anti-cavitation and erosive wear, can adopt in many ways.Current existing high pressure valve easily produces wearing and tearing in use, causes the shortcoming that working life is short.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of compact structure, Wear resistant anti-high pressure, and stability in use can be good, the abrasion resistant type high pressure valve of convenient and reliable operation.
For solving the problem, the utility model adopts following technological scheme:
A kind of abrasion resistant type high pressure valve, comprise valve body, york piece, valve rod and handwheel, described york piece is located on valve body, described york piece is fixedly connected with valve body, described valve rod is located in valve body, described valve rod upper end is that screw thread is arranged, described handwheel is located on valve rod, described handwheel is fixedly connected with valve rod, york piece sleeve pipe is provided with in the middle part of described york piece, described york piece sleeve pipe is connected with threaded stem, described valve body is provided with back seat and gland, described back seat is fixedly connected with gland, pressure sealing ring is provided with in described back seat, described stem bottom is provided with flashboard, described flashboard arranged outside has seat ring.
As preferably, described flashboard is fixedly connected with valve rod, and holding structure is compact.
As preferably, described flashboard is wedge shape flashboard, dams effective.
As preferably, described seat ring is fixedly connected with valve body, and holding structure is reliable and stable.
As preferably, bottom described flashboard, be provided with sealing gasket, the wearing and tearing of flashboard can be reduced.
The beneficial effects of the utility model are: the valve body of setting facilitates the circulation of liquid, flashboard has the function of adjust flux when mobile, simultaneously wear-resistant, handwheel facilitates rotation valve rod, make valve rod increase or decline, york piece can holding structure reliable and stable, it is stable that york piece sleeve pipe can keep valve rod to move, and pressure sealing ring can keep the sealability that valve body is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of abrasion resistant type high pressure valve of the utility model.
