Description
Technical field
The utility model relates to valve field, specifically a kind of plate weldering formula plate valve.
Background technique
Current plate valve receives more concerns as wherein a kind of valve, as keying and the controlling device of control media, plate valve is novel in design, selection is appropriate, test is strict, it is light to operate, having stronger anticorrosion, wear-resisting, erosive wear resistance, is a kind of desirable New Equipments of petroleum industrial circle.The parts of plate valve all adopt integrated processes to form, need higher technological level, and then raised the cost of processing, be unfavorable for the development of industry, being welded to connect is the mode that can effectively reduce costs, but welding plate gate valve on the market generally adopts the mode directly by valve body and valve gap welding, is unfavorable for later maintenance, needs a kind of new welding type plate valve.
Model utility content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of plate to weld formula plate valve, solves the problem that the high and direct welding valve body of current plate valve processing cost and valve gap cause being unfavorable for safeguarding.
The utility model solves the technological scheme that its technical problem adopts: this plate weldering formula plate valve, comprise valve body, body top is connected with valve gap, valve gap is fixed with support, support is connected with guard shield, guard shield is rotatably connected to handwheel, handwheel top is connected with umbrella gear, bevel-gear rotating is connected with valve rod, valve rod is fixed with flashboard, the valve seat being positioned at flashboard both sides is installed in valve body, sealing surface of seat seals with flashboard bi-side and contacts, the attachment face of valve seat is provided with groove, O-ring seals is provided with in groove, valve body is steel plate integrated formed structure, body top assembly welding has the first flange, valve gap is the compressing structure of moulding process, bottom valve gap, assembly welding has the second flange, first flange is connected with the second flange.After arranging like this, valve body adopts steel plate integrated formed structure, and valve gap adopts the compressing structure of moulding process, assembly welding valve body and the first flange again, assembly welding valve gap and the second flange, weld seam again by connection first flange and the second flange, forms the main body of plate valve after non-destructive inspection is qualified.
Valve gap top group is welded with three-flange, and three-flange is connected with support.Three-flange and valve gap assembly welding get up to use, and weld seam uses after non-destructive inspection is qualified, effectively can reduce the weight of valve gap body further, alleviate the labor intensity of assembling in early stage.
Valve seat is provided with oil groove, and the outlet of oil groove is positioned on sealing surface of seat.Oil groove can be used for adding lubricant oil, and the exit position of oil groove is positioned on sealing surface, acts directly on sealing surfaces and flashboard bi-side after being conducive to outflow of lubrication oil like this, reduces the friction between surface, and increase the service life, using effect is good.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, compact, by main body and the attachment portion structure of the critical piece that breaks, the main body of critical piece and attachment portion adopt separately one-body molded processing, then by its assembly welding together, reach the overall object used, not only reduce the difficulty of processing of critical piece, also reduce the weight of parts, improve workmanship, reduce manufacture cost, be suitable for promoting.
