Description
Technical field
The invention belongs to valve and manufacture field, relate to a kind ofly for controlling the stop valve of fluid, particularly relate to a kind of high temperature and high pressure cut-off valve that possesses multiple Placement.
Background technique
Stop valve is for controlling one of vitals of flowing medium, and the flap of existing stop valve adopts fixing tapered substantially, and sealing surface is identical with valve body material.The stop valve of this structure and material will make the sealing surface of valve and flap place produce erosion trace after opening and closing several times under the effect of the high-temperature, high pressure fluid by valve, wreck, carrier performance variation, cause spool, valve village to be leaked, when serious, cause system to sew accident, therefore, this kind of stop valve is not suitable for using under high-temperature and high-pressure conditions.Stop valve is most popular a kind of valve, and why very popular it is, be due in switching process between sealing surface frictional force little, more durable, Lift is little, easy to manufacture, easy to maintenance, is not only applicable to mesolow, and is applicable to high pressure.The closed principle of stop valve is that dependence valve thick stick pressure, fits tightly valve clack sealing surface and sealing surface of seat, stops medium circulation.The not easy to wear and scratch of stop valve sealing surface, good airproof performance, during keying between flap and valve body sealing surface without relative sliding, thereby wearing and tearing with abrade all not serious, good seal performance, long service life.During keying, flap stroke is little, thereby stop valve aspect ratio gate valve is little, has and cuts off very reliably action, makes this valve be suitable as cut-out or adjusting and the throttling use of medium.The structural type of stop valve body has straight-through type, direct current type and right-angle type.Straight-through type is modal structure, but the resistance of its fluid is maximum.Direct current type fluid resistance is less, is used for containing solid particle or the large fluid of viscosity.Right-angle type valve body adopts forging more, be applicable to littlely to stimulate the menstrual flow, elevated pressures stop valve.But the stop valve in existing technology can only be used a Placement connecing with medium pipeline conventionally, the medium pipeline that can not meet different Placements simultaneously envoy with a kind of requirement of stop valve, in actual production, the medium pipeline that the is necessary for different Placements stop valve of different Placements that forms a complete production network.
Summary of the invention
The object of the invention is to overcome the defect existing in prior art, a kind of novel structure, flexible movements are provided, under High Temperature High Pressure, repeatedly open and close the high temperature and high pressure cut-off valve that possesses multiple Placement that still can keep excellent sealing state.
The technical solution used in the present invention is:
A kind of high temperature and high pressure cut-off valve that possesses multiple Placement, comprise valve body, flap, divided ring, valve clack cover, valve rod group component, stainless steel spirotallic gasket, Packing seat, flexible graphite packing, dottle pin, flexible graphite packing, valve gap, Gland, positioning plate, steel ball, Stem Mut, plane bearing, gland, impact block, handwheel, packing ring, gland nut, anti-theft screw, hexagon socket head cap screw, nut, stud bolt, butt joint link, hoop link, flange connector, screw connector, it is characterized in that described divided ring, valve clack cover packs on valve rod successively, valve clack cover is screwed into flap, spot welding is fixed.Valve rod group component is packed in valve body chamber, pack stainless steel wound gasket into, then pack successively Packing seat, flexible graphite packing, dottle pin, flexible graphite packing, Gland into, valve gap is screwed in valve body, with special spanner, tighten.Pack successively positioning plate, steel ball, Stem Mut, plane bearing, gland into, gland is tightened, nut, stud bolt are packed on valve gap, and tighten.Pack successively impact block, handwheel, packing ring, gland nut into, tighten gland nut, anti-theft screw is screwed on gland nut, hexagon socket head cap screw is screwed into a top of the trellis, nut is fixed and clamped.
Further illustrate the present invention, when stop valve is used for the oil and gas pipes of butt welding Placement, at the connection mouth erection welding link of stop valve.
When stop valve is used for the oil and gas pipes of hoop Placement, at the connection mouth assembly ring head link of stop valve.
When stop valve is used for the oil and gas pipes of flange connection, at the connection mouth assembly flange link of stop valve.
When stop valve is used for the oil and gas pipes of screw Placement, the connection mouth at stop valve assembles screw connector.
Valve clack sealing surface of the present invention is arc, and alloy spray-welding is carried out on top layer, and described plane bearing is configured in Stem Mut top and the bottom, and described valve rod adopts double thread screw, and left hand thread is processed into two keyways, makes valve rod only make vertical lift during work.
The present invention compared with prior art, has the following advantages:
Stop valve is supporting butt joint link, hoop link, flange connector, screw connector, make stop valve can be used in the medium pipeline of multiple Placement, the medium pipeline that meets different Placements simultaneously envoy with a kind of requirement of stop valve, valve clack sealing surface is arc, alloy spray-welding is carried out on top layer, under high temperature and high pressure condition, and erosion resistance, non-scaling, long service life.Plane bearing is configured in Stem Mut top and the bottom, and valve rod adopts double thread screw, and rising or falling speed is fast, and switch is convenient.Adopt direct current type structure, medium flow resistance coefficient is little, can be simultaneously applicable on vertical or vertical formula pipe network.Energy saving, improves work efficiency.
