Abstract

The utility model relates to a water drain stifling valve, belongs to the valve domain in machine field. The utility model is applicable to liquid draining, in particular to the draining of the liquid contained solid impurities. The utility model has the technical proposal that a socket is arranged on one end of a tube, an acidproof alkali, high pressure and high water base fibrous composite root coil is placed in the socket, a compression bowl plate is arranged on the root coil, a beam connector with a lead screw and a screw mandrel is fixed on the compression bowl plate, the beam is connected with the ram that is fixed on one end of the tube through a moving pin and a fixed pin, a handwheel is fixed on the screw mandrel. When exhausting liquid contained solid impurities, the utility model has the advantages of long use time, tight sealing, convenient operation and maintenance, no leakage in condition of high pressure.

Description

Stop valve for draining water

(1) technical field: the utility model belongs to the valve field in mechanical.

(2) background technique: valve is of a great variety in the market, and structure and purposes are not a kind of yet.Concentrating the talk of the valve that is used for damming just has gate valve, ball valve and closure plate valve.These valves are used on the pipeline mostly, are used for flow of fluid situation in the controlling plumbing fixtures, during valve opening, and the flow of fluid in the pipeline, when closing, liquid does not just flow.Effect was good when these valves control neat liquids flowed, when control be not neat liquid when flowing effect with regard to not so good.For example control and contain lime-ash in the water, when also just controlling the solid mixed solution of water, the life-span of valve shortens dramatically.Go ahead with regard to gate valve, its sealed faying face is the metal junction plane, and is just poorly sealed when containing solid matter in the water, just produces and leaks, and the life-span is also very short simultaneously.Though the closure plate valve is simple in structure, controlling liquid flows under the incompatibility high pressure conditions, and frequent leakage can't be used under the high pressure shape, and ball valve also is same.Because above-mentioned valve can not be controlled the flow of fluid that contains solid impurity well, therefore the needs design is a kind of can control the flow of fluid that contains solid impurity, and the valve of long service life.

(3) technology contents: the purpose of this utility model will design a kind of can control exactly and contain the solid impurity flow of fluid, seals the Stop valve for draining water of tight and long service life.Major technique is to do a groove on the termination of a pipe, be placed with the high water base fiber composite packing of acid resistant alkali high pressure in the groove, on packing, be pressed with and compress a bowl piece, compress and be fixed with screw mandrel on bowl piece and be connected with the crossbeam that a hole is arranged, crossbeam is connected with the connecting rod that is fixed on the pipe termination with fixing pin with loose pin, fixes a handwheel on the screw mandrel.The utility model major advantage is: adopted mazy type close and adopted the high water base fine compound packing of acid resistant alkali high pressure, and good seal performance, easy to maintenance, long service life, and be fit to discharging and contain solid impurity liquid.

(4) description of drawings: Fig. 1 is a cross-sectional schematic of the present utility model.

(5) entity mode of execution: on a pipe (1) termination, do a groove (14), be placed with the high water base fiber composite packing (3) of acid resistant alkali high pressure in the groove, on packing, be pressed with and compress a bowl piece (4), compress and be fixed with screw mandrel (9) on bowl piece and be connected with the crossbeam that a hole is arranged (7), crossbeam is connected with the connecting rod that is fixed on the pipe termination (2) with fixing pin (12) with loose pin (6), fixes a handwheel (10) on the screw mandrel.The utility model as long as move handwheel, sheds the pressure that compresses on bowl piece, then loose pin (6) is extracted, and just realizes valve is all opened, and just compresses bowl piece servo-actuated crossbeam and rotates around fixing pin (12).Screw mandrel (9) is used for regulating impacting force and uses, and certainly, when not needing all to open, mentions also and can discharge with screw mandrel compressing bowl piece.System pipeline in the course of the work, this model utility is in closed condition.Handwheel is with being processed with one section square on the screw mandrel, handwheel being installed on the square, with nut (11) axial restraint handwheel.When screw mandrel compressing bowl when mentioning discharge liquid, compress the deflection of bowl on anti-, compressing the guide rod (5) of fixing two belt length holes (15) on bowl piece (4), in slotted hole, put a limited post (8), limited post is fixed on the crossbeam (7).Fix a limiting stopper (13) on bowl piece compressing, limiting stopper prevents that screw mandrel from mentioning too high used.When the utility model was connected with extraneous pipe, the effective screw thread of minor diameter connected in this way, connects with flange as large diameter pipe, can certainly adopt the method for welding to connect.The utility model good seal performance is particularly suitable for containing the fixedly fluid discharge of impurity, and is simultaneously easy to maintenance and be applicable to do not leak highly pressurised liquid under high pressure conditions.

Claims

1, a kind of Stop valve for draining water, it is characterized in that: on the termination of a pipe (1), do a groove (14), be placed with the high water base fiber composite packing (3) of acid resistant alkali high pressure in the groove, on packing, be pressed with and compress a bowl piece (4), compress and be fixed with screw mandrel (9) on bowl piece and be connected with the crossbeam that a hole is arranged (7), crossbeam is connected with the connecting rod that is fixed on the pipe termination (2) with fixing pin (12) with loose pin (6), fixes a handwheel (10) on the screw mandrel.

2, a kind of Stop valve for draining water according to claim 1 is characterized in that: compressing the guide rod (5) of fixing two belt length holes (15) on bowl piece (4), put a limited post (8) in slotted hole, limited post is fixed on the crossbeam (7).
