Description
Technical field
The invention belongs to the pump valve field, be specifically related to a kind of pipeline and safeguarded valve fast.
Background technique
Supply water or other industrial feed flow pipe-line systems in break through regular meeting generator tube road or water liquid phenomenon is leaked in valve damage etc., perhaps because valve is embedded in underground corrosion for a long time and loses function.In case pipeline breaking or valve lose function, then need to close for a long time upstream valve and carry out complicated pipeline maintenance, and in some pipe-line systems very complexity or the very important place of pipe-line system, close upstream valve for a long time and will influence the life and the manufacturing operation in downstream, downstream water liquid can produce the phenomenon of backflow after the what is more important pipeline breaking so that damage downstream instrument, instrument or give life, produce bring very serious unfavorable.In case when the generation valve damages or leaks, above-mentioned same problem will take place, therefore the valve that also must more renew not only safeguards complexity simultaneously, changes valve simultaneously and will bring the high problem of maintenance cost.
Summary of the invention
Long in order to solve above-mentioned pipeline breaking maintenance time, the maintenance engineering complexity, and valve damages leakage replacing valve engineering complexity, the problem that cost is high the invention provides a kind of pipeline and safeguards special valve fast, and this valve is the effective upstream and downstream of quick blocking pipeline breaking not only, the valve of alternative former damage also simultaneously, have simple in structure, easy to operate, quick, the clear superiority that maintenance cost is low.
Below a kind of pipeline of the present invention is safeguarded that fast special valve is explained in detail:
A kind of pipeline is safeguarded special valve fast, it comprises upper valve body, following valve body, valve gap, rubber flashboard, valve rod, wherein the inwall of upper valve body is welded with the guiding rib of guiding rubber flashboard, one side of upper valve body be provided with valve body in connect to insert the supporting base of special-purpose cutting pipe running tool, supporting base is provided with end cap, and end cap is provided with plug; Upper valve body passes through bolton together with following valve body, and its joint is provided with seal ring; Valve gap is provided with two suspension ring, is provided with the nut that meshes with threaded stem in the valve gap, and valve gap and upper valve body pass through bolton together, and its sealing part is provided with middle mouth sealing ring; One end and the rubber flashboard of valve rod link together, and the other end passes valve gap and is provided with the driving cap; The rubber flashboard is located in the guiding rib of upper valve body, and acts on vertical-lift in upper valve body and the following valve body, decline by what drive cap and nut in guiding rib.
A kind of pipeline of the present invention is safeguarded special valve fast, when being used to safeguard burst pipe, upstream and downstream certain position at rent carries out housekeeping operation simultaneously, promptly load onto two these special valves simultaneously at the upstream and downstream certain position at burst pipe place, special-purpose cutting pipe running tool is installed on the supporting base of the upper valve body of this special valve then, utilize the whirligig and the slitting wheel of this instrument pipeline radially to be cut the otch that can place the rubber flashboard while rotating this valve, behind the otch this special valve is screwed to initial position, rotation drives cap the rubber flashboard is placed in the conduits cut, thereby plays plugging action; Behind the pipe plugging, then rent is safeguarded, safeguarded that back rotation rotation drives cap the rubber flashboard is raised up with dredging pipeline from incision; Behind the pipe-dredging, the special use cutting pipe running tool of installing on the supporting base is removed, with end cap and plug supporting base is shut then.
The isolated plant that special-purpose cutting pipe running tool of the present invention designs for the claimant.
A kind of pipeline of the present invention is safeguarded special valve fast, when being used for safeguarding the damage valve, on the upstream line position of damaging valve, load onto this special valve, carry out the shutoff upkeep operation by aforesaid operations, pipeline with same specification after the shutoff is connected with the upstream line of valve, after the connection special use cutting pipe running tool of installing on the supporting base is removed, with end cap and plug supporting base is shut then, then utilize the lifting of rubber flashboard and decline effect to play the effect that substitutes former valve.
A kind of pipeline of the present invention is safeguarded special valve fast, and the claimant has done effective analysis and test, under same pipeline condition, can be not related to and close the trip valve and finish maintenances such as shutoff, mediation in 30 minutes, and its positive meaning is:
At first, can be not related to close the trip valve in the quick blocking burst pipe liquid of swiming up and down, make the water liquid of upstream be unlikely to the long-time waste of leaking, also can avoid upstream valve to close for a long time and influence other purposes of pipe-line system; Can also make simultaneously the water liquid in downstream be unlikely to reflux or reflux few, can avoid the downstream because of lack of water liquid bring not convenient, instrument, instrument or other devices in protection downstream are not received loss have tangible effect.
Secondly, can substitute the valve that original damage is leaked, have tangible effect reducing the pipeline maintenance cost.
