Description
Technical field
The present invention relates to valve field, especially a kind of ball valve opening and closing element and spherical containing itMonocline weld seam all-welded ball valve.
Background technology
Through the continuous evolving development of last 100 years, up to the present, it is two large that ball-valve structure mainly containsClass. One class is multisection type assembling ball valve (two-part, syllogic). Use bolt by each section of companyConnect and assemble, each intersegmental by seal realize sealing prevent reveal. In use,If reveal, can change internals or overhaul by dismounting. Another kind of is full solder sphereValve. After assembly welding moulding, valve body is without leak point. In use, if internals damage,Non-dismountable maintenance.
At present, the profile of all-welded ball valve both domestic and external mainly contains tubular and is similar to spherical two kinds.Some tubular ball valves are welded by two circular welds perpendicular to latus rectum axis, in the middle of comprisingSection, upper lower valve rod pin axial sleeve and two ends nozzle belt, i.e. three sections of assembly weldings. Existing two-partThe assembly welding weld seam of approximate spherical single weld seam all-welded ball valve is actual is girth joint face and pipeline drift diameterAxis is vertical and overlaps with upper lower valve rod concentric axis, symmetrical twice semi-circular weld seam with up and downValve rod pin axial sleeve forms with the crossing assembly welding of the little circular weld of twice of spherical halved body assembly welding,By two little welding ring weld seams of the large circular weld disconnecting together and upper lower valve rod pin axial sleeveIntersect, do not claim it is a continuous full circle monocycle weld seam. All-welded ball valve because of postwelding can not be againDismounting, the more few overall performance that is more conducive to valve of weld seam quantity that therefore final assembling is shaped.Best perfect condition should be continuous girth joint one.
No matter be assembly type ball valve or full side welded ball valve, its inner opening and closing element is identical.Opening and closing element is to be formed by a spheroid and a pair of floating seal valve seat combination of upper downstream side. Spheroid existsUnder the drive of coupled valve rod around the 90 ° of realizations that turn clockwise of the concentric axis of upper lower valve rodBall valve is closed, and is rotated counterclockwise 90 ° and realizes unlatching, and its sealing is top downstream side floating valve seatUnder the effect of one group of spring force, making its sealing surface of seat be affixed to all the time spherome surface is in contact with itProduce initial sealing specific pressure and ensure low pressure seal, under pressure medium effect, realize total head simultaneouslyPoor lower two-way hermetically sealed.
There is following problem in existing all-welded ball valve:
1) the inside and outside structure of each section of all-welded ball valve is all that rough forging processes, materialLow, the processing capacity of utilization rate large, length expends time in. In particular for submarine oil and natural gasCarry and use special material all-welded ball valve, as used nickel-bass alloy material, the processing of valve body moreDifficulty, cost is high.
2) because all-welded ball valve is all to implement welded closure after assembling, postwelding can not enterWelding stress is eliminated in the conventional heat treatment of row, and therefore weld seam is more few better. Existing syllogic cylinderShape ball valve is by twice circular weld welding fabrication; In welding first weld seam process, stage casingThe not yet welded seam of an other side and adjacent Butt Section are in unconfinement state, so size essenceDegree is difficult to ensure; And in the time of welding second weld seam, because first has completed the weld seam of weldingConstraint make again the size of twice balanced welding seam welding rear valve body both sides be difficult to ensure complete oneCause, can not meet bilateral symmetry requirement. And just as mentioned before, existing approximate spherical two sectionsThe what is called list weld seam assembly welding of formula ball valve is actual is by lower valve rod pivot on two and half girth joints and valve bodyCrossing the forming of the little circular weld of twice welding simultaneously of axle sleeve, is not real single weld seam, andAnd weld seam is discontinuous, and weld seam intersection is that requirement is avoided in design of pressure vessels specification, be unallowed to high-tension apparatus especially.
3) non-dismountable after assembly welding because of all-welded ball valve, requiring valve internals is valveThe potted component of most critical, i.e. spheroid and sealing surface of seat, should with welding valve body equivalent life.And in fact, existing ball valve valve is in opening and closing process, because needs rely on upper and lowerStream side floating valve seat makes sealing surface of seat be affixed to all the time spherome surface also under the effect of spring forceBe in contact with it produced initial sealing specific pressure and ensure low pressure seal, make sealing surface of seat withSpherome surface remains contact friction, and therefore in During Process of Long-term Operation, very easily scratch damages.Assembling formula ball valve for bolt can be removed for repair or replacement, and for full solder sphereValve can not, so the internals of existing all-welded ball valve (sealing surface) can not with welding valveBody equivalent life.
Therefore, need a kind of new spherical monocline weld seam all-welded ball valve, it is at spheroid, valve seatSwitching process is without friction, long service life, and processing is simple, only has single weld seam.
