Description
Technical field
This utility model relates to valve field, a kind of ball valve opening and closing element and the spherical monocline weld seam all-welded ball valve containing it.
Background technology
Through the continuous evolving development of last 100 years, up to the present, ball-valve structure mainly has two big classes.One class is that multisection type assembles ball valve (two-part, syllogic).Use bolt to assemble each section and form, each intersegmental realize sealing by sealing member and prevent from revealing.In use, if revealing, internals can be changed by dismounting or overhauling.Another kind of is all-welded ball valve.After assembly welding molding, valve body is without leak point.In use, if internals are damaged, non-dismountable maintenance.
At present, the profile of all-welded ball valve both domestic and external mainly has tubular and approximate sphericity two kinds.Some tubular ball valves are welded by two circular welds being perpendicular to latus rectum axis, including interlude, upper lower valve rod pin axial sleeve and two ends nozzle belt, i.e. three sections assembly weldings.The assembly welding weld seam really girth joint face of existing two-part approximate sphericity list weld seam all-welded ball valve is vertical with pipeline drift diameter axis and overlaps with upper lower valve rod concentric axis, the twice semi-circular weld seam of symmetry intersects assembly welding with the little circular weld of twice of upper lower valve rod pin axial sleeve with spherical halved body assembly welding and forms, i.e. being intersected by the big circular weld disconnected together welding ring weld seam little with two of upper lower valve rod pin axial sleeve, not claiming is a continuous print full circle monocycle weld seam.All-welded ball valve can not be dismantled because of postwelding again, is therefore finally assembling to the fewest more beneficially valve the overall performance of weld seam quantity of shape.Optimal perfect condition should be one continuous print girth joint.
Either assembled ball valve or full side welded ball valve, its internal opening and closing element is identical.Opening and closing element is to be formed by a pair floating seal valve seat combination of a spheroid and upper downstream side.Spheroid under the drive of coupled valve rod around on the concentric axis of lower valve rod turn clockwise 90 ° and realize ball valve and close, half-twist realizes opening counterclockwise, it seals is that top downstream side floating valve seat makes its sealing surface of seat be affixed to spherome surface all the time to be in contact with it generation initial sealing than pressure to ensure low pressure seal, realize under total head difference two-way hermetically sealed under pressure medium effect simultaneously under the effect of one group of spring force.
Existing all-welded ball valve there is problems in that
1) the inside and outside structure of each section of all-welded ball valve is all that rough forging processes, and the utilization rate of material is low, processing capacity big, it is long to expend the time.In particular for submarine oil and natural gas conveying special material all-welded ball valve, as used nickel-bass alloy material, the processing of valve body is more difficult, and cost is high.
2) being to implement welded closure after all assembling due to all-welded ball valve, postwelding can not carry out the heat treatment of routine and eliminate welding stress, and therefore weld seam is the fewest more good.Existing syllogic tubular ball valve is by twice circular weld welding fabrication；During welding first weld seam, the not yet welded seam of stage casing other side is in unconfinement state with adjacent Butt Section, thus dimensional accuracy it is difficult to ensure that；And when welding second weld seam, the constraint of the weld seam having completed welding due to first makes again the size of twice balanced welding seam welding rear valve body both sides be difficult to ensure that completely the same, it is impossible to meet lateral symmetry requirement.And as previously mentioned, the so-called single weld seam assembly welding of existing approximate sphericity two-part ball valve really by two and half girth joints with on valve body while of the twice of lower valve rod pin axial sleeve little circular weld welding intersect and form, it it is not real single weld seam, and weld seam is discontinuous, and weld seam intersection is requirement in pressure vessel design code avoids, it is unallowed to high pressure equipment especially.
3) because of all-welded ball valve after assembly welding non-dismountable, it is desirable to the valve internals i.e. potted component of valve most critical, i.e. spheroid and sealing surface of seat, it should with weld valve body equivalent life.And actually, existing ball valve valve is during opening and closing, owing to needs rely on upper downstream side floating valve seat to make sealing surface of seat be affixed to spherome surface all the time and be in contact with it produced initial sealing than pressure to ensure low pressure seal under spring force, sealing surface of seat is remained with spherome surface and contacts friction, in During Process of Long-term Operation, therefore easily abrade damage.Formula ball valve is assembled for bolt can be removed for repair or replacement, for all-welded ball valve then can not, so the internals of existing all-welded ball valve (sealing surface) can not with weld valve body equivalent life.
Accordingly, it would be desirable to a kind of new spherical monocline weld seam all-welded ball valve, it is in spheroid, valve seat switching process without friction, and service life is long, and processing is simple, only single weld seam.
