Abstract
The invention discloses a motor-driven bellows inclined type welded valve-body stop valve and relates to a motor-driven stop valve, which comprises an inclined type welded valve body. The motor-driven bellows inclined type welded valve-body stop valve is characterized in that: a Co-based hard alloy sealing ring is formed on the inclined type welded valve body by surfacing; a titanized austenitic stainless steel bellows device is flexibly and mechanically connected below a valve rod and above a valve clack; pads are embedded into convex and concave contact positions of the inclined type welded valve body and a valve cap, so that the inclined type welded valve body and the valve cap are mechanically connected by springs, bolts, pads and nuts; a packing pad is arranged in a packing box on the valve cap, the packing is covered by a packing gland, and the packing gland is mechanically connected with the valve cover by a jacking screw and a jacking nut on the valve cover; and the upside of the valve rod is arranged in a mandrel sleeve of a motor driving head and mechanically connected with the same, and the lower head of the valve rod is flexibly and mechanically connected with the valve clack. The motor-driven bellows inclined type welded valve-body stop valve is applicable to pipes of various working conditions such as petroleum industry, chemical industry and the like to switch on and off a pipe medium.
Description
Technical field:
The present invention relates to a kind of motor-driven stop valve, a kind of specifically motor-driven bellows inclined type welded valve-body stop valve.
Background technique:
At present, known stop valve, the open-shut device with stop valve are the flaps of plug type, and sealing surface is the plane or the conical surface, the center line moving linearly of flap longshore current body.The movement pattern of valve rod has elevating lever-type, and lifting rotation rod-type is also arranged.Stop valve only is applicable to standard-sized sheet and complete shut-down, does not allow to do to regulate and throttling.Belong to forced seal formula valve,, do not leak with forced seal face so when valve closing, must exert pressure to flap.When medium enters valve by the flap below, the required resistance that overcomes of steering force is the frictional force of valve rod and filler with by the thrust that pressure produced of medium, the power that the force rate of closing valve is opened valve is big, so it is big that the diameter of valve rod is wanted, otherwise the fault of valve rod bending can take place.
Summary of the invention:
The invention provides a kind of motor-driven bellows inclined type welded valve-body stop valve,, must exert pressure to flap to solve stop valve forced seal formula valve when closing, the technical problem that forced seal face does not leak,
For realizing purpose of the present invention, the present invention adopts following technological scheme: a kind of motor-driven bellows inclined type welded valve-body stop valve, comprise inclined type welded valve body, it is characterized in that built-up welding Co base cemented carbide seal ring on the inclined type welded valve body, the active mechanical connection of titanizing Austenitic Stainless Steel bellows arrangement is below the valve rod and between above the flap, inclined type welded valve body contacts the convex-concave place and is embedded with bolt spring pad nut mechanical connection by pad with valve gap, put down in the stuffing box on the valve gap Packing seat filler by Gland with the jack screw on the valve gap by very heavy nut mechanical connection, the valve rod top fits over mechanical connection in the motor driving core sleeve, the active mechanical connection of square toes and flap under the valve rod, a motor driving core sleeve fits in the motor driving mandrel by motor driving head unit mechanical connection, a motor driving mandrel one changes through a motor driving core sleeve makes the valve rod lifting bar drive the lifting of titanizing Austenitic Stainless Steel bellows arrangement, valve gap top endoporus gas-distributing motor driving head core sleeve mechanical connection, interior gas-distributing motor driving head mandrel is by motor driving core sleeve's lateral pin mechanical connection in the motor driving core sleeve.
Owing to adopt such scheme, simple in structure, easy for installation, flange connects convenient disassembly, dual robust bellows convenient disassembly, and product structure is reasonable, sealing is reliable, and dual robust sylphon seal design guarantees the zero leakage of valve rod.Do not have fluid loss, reduce energy loss, improve safety of factory equipment.Sealing surface weld deposit Co base cemented carbide, wear-resisting, corrosion resistant, good, the long service life of friction resistant performance, bellows titanizing Austenitic Stainless Steel is wear-resisting, corrosion resistant, good, the long service life of friction resistant performance, modified and the surfaces nitrided processing of valve rod has good anti-corruption and friction resistant performance; The indication of valve rod lifting position, more directly perceived, be applicable on the pipeline of various operating modes such as oil, chemical industry, cut off or connect the pipeline medium.
