Abstract
The utility model relates to a clamp valve which comprises a valve body, a valve plate in the valve body and a valve pole which is connected with the valve plate and is extended out of the valve body; the outlet and inlet of the valve are provided with a sealing surface which is contacted with the connector of the pipe flange; the outlet and inlet of the valve have no flange; the sealing surface of the outlet and inlet of the valve is connected with the flange sealing surface of the pipe; the screw passes through the pipe flange holes in the two sides of the outlet and inlet to hold the valve in the pipe. The screw is contacted with the outer edge or positioning port of the valve. The upward side of the valve is provided with a screw connecting hole with a pipe flange to bring convenience to the connection. One side of the valve plate is corresponding with the valve port and the other side of the valve plate is an incline surface which is corresponding with the incline plane of the valve. The utility model can ensure the reliability of the sealing.
Description
Technical field:
The wafer type gate valve is a kind of gate valve, linkage structures such as the import and export of valve are not threaded, flange, but grip by the pipeline that is communicated with.
Background technique:
Existing gate valve is connected by the flashboard in valve body, the valve body, with flashboard and the valve rod that stretches out valve body is formed, and the valve body import export is and the pipeline flange flange connecting.Flange has the sealing surface of relative contact with pipe interface and the flange plate of sealing surface outer rim, and flange plate has the hole of distribution, after pipeline flange docks, passes relative flange hole with bolt and connects, and is assembled in the pipeline.Because the import export of gate valve has adpting flange, makes that the gate valve volume weight is bigger.Simultaneously, make that the import export of gate valve is darker, increased the difficulty that stretches into cutter processing body cavity and valve port from import export.Two corresponding contacts of relative valve port in flashboard both sides and valve body in addition, the machining accuracy of usage requirement is higher, though be two contact seal faces since two sides of flashboard always with the valve port friction that interlaces repeatedly, use just leakage easily after a period of time.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, volume weight is less, the wafer type gate valve being convenient to process, and the wafer type gate valve that further provides flashboard and valve port to be more convenient for sealing.
Wafer type gate valve of the present utility model is connected by the flashboard in valve body, the valve body, with flashboard and the valve rod that stretches out valve body is formed, and it is characterized in that: the valve body import export has only the sealing surface of relative contact with the pipeline flange interface.The valve body import export does not have flange, and the sealing surface of valve body import export docks with the flange facing of pipeline, bolt is passed the pipeline flange hole of import export both sides and tightens, and just the gate valve clamping is communicated with fixedly in the pipeline.The bolt that connects clamping both sides pipeline flange preferably contacts with valve body outer rim or positioning port, more effectively fixed valve body.More pipeline is connected for distributing with flange hole, in order not have the hole of passing bolt on valve body top, avoid structure and machining complexity, the screw that the local bolt that has with pipeline flange is connected above the valve body import export is so that be connected with the comprehensive of pipeline flange.In order further to simplify the difficulty of processing, increase the sealing reliability of flashboard and valve port equally, flashboard one side is still corresponding with the valve port of valve body, and the flashboard opposite side is inclined-plane and corresponding with the inclined surface of valve body.That is to say that to be the inclined-plane between flashboard one side and the valve body corresponding.Like this, flashboard and valve port merge when closing, and by the ramp effect of opposite side, make a side of flashboard be easy to bear against at valve port and well seal, and flashboard and valve port have some wearing and tearing also can lean on the effect that bears against on inclined-plane to be compensated, and guarantee the reliability of sealing.
Compared with the prior art, the structure with valve body is simplified greatly, has reduced the volume and weight of gate valve; The quality of processing of the import and export of the valve body narrower and shallower processing that is beneficial to very much valve inner, particularly valve port, thus greatly reduce the cost of gate valve; Also be convenient to simultaneously installing and using and repair and replacement of gate valve.
Description of drawings:
Accompanying drawing has been represented the structural representation that a kind of the utility model gate valve is connected with pipeline, and wherein Fig. 1 is main sectional view, and Fig. 2 is the side half sectional view.
Embodiment:
Example below in conjunction with accompanying drawing further specifies the utility model.This wafer type gate valve of the present utility model is connected by the flashboard 5 in valve body 2,3, the valve body, with flashboard and stretches out the valve rod 1 of valve body 2 and the handwheel of fixedlying connected with valve rod is formed.Its structural feature is: the valve body import export has only the sealing surface 6 of relative contact with the pipeline flange interface, and the valve body import export does not have flange.The sealing surface of valve body import export docks with the flange of pipeline 4 sealing surfaces, and connecting bolt 7 is passed import, the outlet pipeline flange hole of both sides and the nut that tights a bolt, just with gate valve clamping connection fixedly in the pipeline.The bolt that connects clamping both sides pipeline flange contacts the location with the valve body outer rim.More pipeline is connected for distributing with flange hole, the screw 8 that the local bolt that has with pipeline flange is connected above the valve body import export, so that the bolt 12 of pipeline flange top passes the piping flange hole and is screwed into screw 8 and is connected and fixed, the valve body import export closely is communicated with comprehensively with pipeline.In order to increase the sealing reliability of flashboard and valve port, flashboard one side 9 is still corresponding with the valve port of valve body, and flashboard opposite side 10 is inclined-plane and corresponding with the inclined surface 11 of valve body.It is corresponding to be the inclined-plane between this side of flashboard and the valve body.Flashboard and valve port merge when closing, and the ramp effect by this side makes flashboard be easy to bear against at valve port, form well sealing, and flashboard and valve port have some wearing and tearing also can lean on the effect that bears against on inclined-plane to be compensated, and guarantee the reliability of sealing.
Claims (3)
1, a kind of wafer type gate valve is connected by the flashboard in valve body, the valve body, with flashboard and the valve rod that stretches out valve body is formed, and it is characterized in that: the valve body import export has only the sealing surface of relative contact with the pipeline flange interface.
2, as the said wafer type gate valve of claim 1, it is characterized in that: import export top is local to have the screw that the bolt with pipeline flange is connected.
3, as claim 1 or 2 said wafer type gate valves, it is characterized in that: flashboard one side is corresponding with the valve port of valve body, and the flashboard opposite side is inclined-plane and corresponding with the inclined surface of valve body.
