Abstract
The utility model belongs to the technical field of pipeline rehabilitation, especially, relate to a leaking stoppage valve is pressed to pitch diameter pipe racks, including case and valve body, the case be a hexagon head bolt, the case passes through threaded connection on the valve body, the afterbody of case is provided with sealed a pad, sealed fill up through the fix with screw on the case, the valve body for central authorities are equipped with the cylindric structure of through -hole, be provided with a round platform in the valve body, round platform and tail end crush seal pads of case are realized sealedly, position welding that the middle part of the valve body outside and threaded connection section corresponds has a return bend, the return bend communicates with valve body inside and formed the liquid passageway, does not have screwed one end to weld on the valve body and has a horn mouth. Sealed pad make by the red metal. Total two of return bend, two return bend symmetries set up the both sides at the valve body. Use the utility model discloses can carry out quick leaking stoppage under the circumstances about not stopping production, not only can not lead to the fact the influence to production among the reparative process, remediation efficiency is high in addition.
Description
Technical field
The utility model belongs to pipe rehabilitation technology field, particularly relates to a kind of central diameter pipe racks pressure leaking stoppage valve.
Background technique
Cemented filling is a kind of conventional liquid supplying way, and pipeline in use can produce damaged because of reasons such as burn into are aging, and then causes the leak of liquid in pipeline.When occurring to leak, need to repair leak source, this reparation adopts the method for repair welding usually.There are the following problems for this method: during repair welding, in order to avoid the liquid flowed out hinders welding operation, needs, by after equipment stopping production, by ducted pressure dump, even to need the liquid in emptying pipe.Not only affect production, repair efficiency is also lower.
Summary of the invention
The utility model provides a kind of central diameter pipe racks to press leaking stoppage valve, produces and the low problem of repair efficiency to solve the existing pipe repairing method impact proposed in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of central diameter pipe racks pressure leaking stoppage valve, comprise spool and valve body, described spool is a hexagon head bolt, spool is threaded connection on valve body, the afterbody of spool is provided with a sealing gasket, sealing gasket is fixed by screws on spool, described valve body is the cylindrical-shaped structure that central authorities are provided with through hole, a round platform is provided with in valve body, the tail end crush seal of round platform and spool pads existing sealing, position corresponding with the middle part of the section of being threaded outside valve body is welded with a bend pipe, bend pipe is communicated with valve inner and formed liquid passage, valve body does not have threaded one end be welded with a horn mouth.
Above-mentioned sealing gasket is made up of red metal.The arranged outside at above-mentioned bell-mouthed edge has bevel for welding.Above-mentioned bend pipe has two, and two bend pipes are symmetricly set on the both sides of valve body.Above-mentioned bend pipe comprises main paragraph and is located at 90 ° of elbows of main paragraph one end, and the axis of main paragraph and the axes normal of valve body, bend pipe is connected with valve body 90 ° of elbows.
The beneficial effects of the utility model are: using the utility model can carry out instantaneous leaking-stopping when not stopping production, not only can not impact production in repair process, and repair efficiency is high.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the left view of Fig. 1.
In figure: 1-spool, 2-valve body, 3-sealing gasket, 4-screw, 5-horn mouth, 6-bevel for welding, 7-bend pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
The utility model comprises spool 1 and valve body 2, described spool 1 is a hexagon head bolt, spool 1 is threaded connection on valve body 2, the afterbody of spool 1 is provided with a sealing gasket 3, sealing gasket 3 is fixed on spool 1 by screw 4, described valve body 2 is the cylindrical-shaped structure that central authorities are provided with through hole, a round platform is provided with in valve body 2, the tail end crush seal pad 3 of round platform and spool 1 realizes sealing, position corresponding with the middle part of the section of being threaded outside valve body 2 is welded with a bend pipe 7, bend pipe 7 formed liquid passage with valve body 2 inner connection
Comparatively large in order to adapt to pipe diameter, the user demand of leakage rate faster under operating mode, special do not have threaded one end to be welded with a horn mouth 5, with the water conservancy diversion that better confluxes on valve body 2.
For ensureing sealing effect further, take into account the reliability of working life and sealing simultaneously, described sealing gasket 3 is made up of red metal.
For the ease of welding, the arranged outside at the edge of described horn mouth 5 has bevel for welding 6.
Asked and ensured enough large liquid latus rectum excessively, described bend pipe 7 has two, and two bend pipes 7 are symmetricly set on the both sides of valve body 2.
Described bend pipe 7 comprises main paragraph and is located at 90 ° of elbows of main paragraph one end, and the axis of main paragraph and the axes normal of valve body 2, bend pipe is connected with valve body 2 90 ° of elbows.
During use, valve is opened (being namely liquid channels open), then valve body 2 will be placed in the leak source of pipeline with one end of horn mouth 5, leakage flows into valve body 2 along horn mouth 5 and guides other places into by bend pipe 7, now by horn mouth 5 one end and pipeline seam, finally tighten spool 1 and make valve closes, complete shutoff.
Using the utility model can carry out instantaneous leaking-stopping when not stopping production, not only can not impact production in repair process, and repair efficiency is high.
