Abstract
The utility model discloses a high-temperature and high-pressure stop valve, which comprises a valve body, a valve clack, a valve clack cover, a valve rod, a bracket, a valve rod guide seat, a plane bearing, a valve rod nut, a hand wheel and an impact block. After a bracket stuffing box and the upper end part are assembled, the valve clack cover and a split ring are respectively arranged in the valve rod; the valve clack and the valve clack cover are screwed to be in spot welding; a graphite pad is arranged in the valve body; the bracket is arranged in the valve body; the impact block is arranged on the valve rod; the hand wheel is arranged to the valve rod nut; an anti-theft nut is arranged to the upper end part of the valve rod nut through a set screw; an oil cup is connected onto the bracket; and an angle of 45 degrees is formed between the axis at the connecting end of the valve body and the axis of the valve rod, and thus, a straight flow type structure is formed. The sealing surface of the valve clack is in an arc shape; the surface layer of the valve clack is subjected to alloy spray welding; the plane bearing is arranged at the upper part and the lower part of the valve rod nut; the valve rod adopts double start threads; the left thread is machined into a dual-key slot; when the high-temperature and high-pressure stop valve is in work, the valve rod is ensured to only vertically lift; and the high-temperature and high-pressure stop valve has the advantages of erosion resistance, scaling resistance, high lifting speed and small medium flow resistance coefficient, and can be simultaneously used on a vertical or longitudinal pipeline network.
Description
Technical field
The utility model relates to a kind of stop valve that is used to control fluid, particularly relates to a kind of medium temperature and can reach the high temperature and high pressure cut-off valve that 500 ℃, pressure reach as high as 48Mpa.
Background technique
Stop valve is to be used for one of vitals of control flows body 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 produce with the flap place after opening and closing several times under the effect of the high-temperature, high pressure fluid by valve to lose trace, wreck, the carrier performance variation, cause spool, valve village to be leaked, cause system to sew accident when serious, therefore, this kind stop valve is not suitable for using under high-temperature and high-pressure conditions.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of novel structure, flexible movements are provided, and opens and closes the high temperature and high pressure cut-off valve that still can keep the excellent sealing state under High Temperature High Pressure repeatedly.
The technical solution adopted in the utility model is:
High temperature and high pressure cut-off valve comprises valve body, flap, divided ring, flap lid, valve rod, graphite pads, support, Packing seat, asbestos packing, filler, dottle pin, filler A, asbestos packing A, Gland, bolt, nut, stem guiding seat, plane bearing, Stem Mut, plane bearing A, pin, bearing nut, handwheel, impact block, label, anti-theft nut, Cock screw, lubricating cup.It is characterized in that described Packing seat, asbestos packing, filler, dottle pin, filler A, asbestos packing A, Gland, the bolt support of packing into, nut is screwed on the bolt of support and tightens and put in place, in the support upper end, with the stem guiding seat, plane bearing, Stem Mut, the plane bearing A support of packing into successively, pack on it bearing nut and have pin to be fixed on the support, after above-mentioned support stuffing box and upper end part assembling are finished, flap is covered, divided ring is respectively charged into valve rod, flap and flap lid are tightened spot welding, again with the graphite pads of packing in the valve body, the support valve body of packing into, impact block is encased on the valve rod, handwheel is encased on the Stem Mut, and anti-theft nut is encased in the Stem Mut upper end portion by Cock screw, and lubricating cup is connected on the support.
Valve body connecting end axis described in the utility model and valve rod axis angle at 45 are the direct current type structure.
Flap sealing surface described in the utility model is an arc, and the alloy surfacing is carried out on the top layer, and described plane bearing is configured in the 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 utility model compared with prior art has the following advantages:
1, the flap sealing surface is an arc, and the alloy surfacing is carried out on the top layer, under high temperature and high pressure condition, and erosion resistance, non-scaling, long service life.
2, plane bearing is configured in the Stem Mut top and the bottom, and valve rod adopts double thread screw, and rising or falling speed is fast, and switch is convenient.
3, adopt the direct current type structure, the medium flow resistance coefficient is little, can be suitable for simultaneously on vertical or vertical formula pipe network.
