Abstract
A threaded connection soft seal butterfly valve comprises a valve body, a valve plate assembly, a valve rod, a sealing pad, a pressing cap, a handle and a nut. An axially hollow cavity is formed in the valve body, the valve plate assembly is arranged in the cavity of the valve body, the valve rod is arranged in the cylindrical cavity in the upper portion of the valve body, the sealing pad is arranged between the valve rod and the valve body and fixed through the pressing cap, and the valve rod is connected with the valve plate assembly and the handle. The threaded connection soft seal butterfly valve is characterized in that internal threads are machined at the two ends of the valve body in the axial direction so that the butterfly valve can be connected with a pipe through threads. A sealing ring is fixed through welding of a left clamping plate and a right clamping plate, the sealing ring is fixed reliably and not prone to disengagement, and valve failure caused by disengagement of the sealing ring cannot happen. The butterfly valve is connected with the pipe through the threads, and the threaded connection soft seal butterfly valve is compact in structure, convenient to install, wide in application range and capable of being widely applied to water supply pipes, heat supply pipes and oil supply pipes.
Description
Technical field
The present invention relates to a kind of butterfly valve, especially the one soft sealing butterfly valve that is threaded.
Background technique
At present, industrial valves door type is various, can be widely used in the industries such as chemical industry, food, water, electricity, mainly plays Flow-rate adjustment and the cut-off effect of flowing medium.
Butterfly valve refers to that valve plate rotates to reach a kind of valve of open and close around valve shaft, and on pipeline, main rising cut off and throttling use.Butterfly valve rises and closes part is a discoidal valve plate, and the axis around himself in valve body rotates, thereby plays the object that opens and closes and regulate.Two kinds of seal form of the flexible soft seal of butterfly valve and metal hard-sealing, the seal ring of soft seal can be embedded on valve body or be attached to valve plate periphery, good seal performance; The valve of hard sealing is generally long than the life of valve of soft seal, can the higher working environment of Applicable temperature, but that sealability is not so good as soft seal is good.No matter the rubber seal of traditional soft sealing butterfly valve is fixed on valve body is still fixed on valve plate; all need with pressing plate or screw, rubber seal to be fixed; and under normal circumstances; the seal face of pressing plate and rubber seal is plane parallel to each other; make like this rubber seal fixing unreliable; be easy to come off, often can occur in actual use to make the situation of valve invalidation because seal ring comes off.In addition, most butterfly valve connects with all adopting flange being connected of pipeline, is not suitable for the occasion low at pressure, caliber is little and installs.
Summary of the invention
Technical problem to be solved by this invention is a kind of being threaded providing for the above-mentioned state of the art, and the adeciduate Novel threaded of seal ring connects soft sealing butterfly valve.
The present invention solves the problems of the technologies described above adopted technological scheme: the one soft sealing butterfly valve that is threaded, comprise valve body, valve board assembly, valve rod, sealing gasket, clamping cap, handle and nut, wherein in valve body, there is the cavity of an axial hollow, valve board assembly is arranged in valve body cavity, valve rod is arranged in the top tubular cavity of valve body, between valve rod and valve body, there is sealing gasket, sealing gasket is fixed with clamping cap, valve rod connection valve board component and handle, be characterized in: the axial two ends of described valve body are processed with internal thread, can be connected in the mode of screw thread with pipeline.
As improvement, the bottom of described valve body is provided with valve rod positioning hole, can coordinate with valve rod location.
As improvement, described valve board assembly comprises seal ring and left and right two clamping plates, in the middle of left and right two clamping plates wraps in seal ring, and fixes by spot welding.
As improvement, the cross section of described seal ring is pentagon; Corresponding, on described clamping plate, be provided with the curved surface coordinating with seal ring.
As improvement, described seal ring respectively has a through hole up and down, can pass valve rod; Described clamping plate have outwardly groove, after left and right two clamping plates spot welding is fixing, form a through hole, can pass valve rod; Corresponding, valve rod, through after valve board assembly, is fixed by spot welding between valve rod and left and right clamping plate, prevents from relatively rotating between valve rod and valve board assembly.
Compared with prior art, the invention has the advantages that: seal ring is welded and fixed by left and right clamping plate, seal ring is fixing reliable, and difficult drop-off, can not occur to make valve invalidation phenomenon because seal ring comes off.The present invention adopted and is threaded with being connected of pipeline, compact structure, and easy for installation, Applicable scope is large, can be widely used in water supply, heating, oil feed line.
