Connection part between described wiper and plugging device is the mutual movable connection structure steerably of spherical gland and hemisphere connecting rod.
Hydraulic oil conduit is provided with in the outer wall of the middle guide rod of described plugging device, the moving member of described middle guide rod periphery is movable liquid compressing cylinder, an outlet of described hydraulic oil conduit is communicated with the front side of movable liquid compressing cylinder, another outlet of hydraulic oil conduit is communicated with the rear side of movable liquid compressing cylinder, promotes hydraulic jack backward or forward back and forth movement respectively.
Described moving member and a spring guide be arranged in parallel carry out coming and going the guiding control connection moved in parallel.
In the cavity of described wiper, be also provided with controller and the remote controller supporting with controller, this controller and described power plant carry out operation control connection.
Working principle of the present utility model:
First need according to the pressure in pipeline wiper and the plugging device of selecting suitable quantity, wiper is placed on rear and front end, middle placement plugging device, wiper and shutoff train are connected, put into pipeline, and by controlling the air pressure in pipeline, allowing pipeline internal air pressure promote this shutoff train and moving to desired location in pipeline.Then start remote controller, started by the controller of shutoff train inside, controller starts power plant, power plant to moving member in plugging device as movable liquid compressing cylinder provides power as hydraulic oil, hydraulic jack moves forward, and makes the rubber ring deformed dilation of plugging device, seals with tube wall; The wedge-like body of moving member periphery moves forward simultaneously, is supported by the wedge-like body bottom slips, slips is extended out, and clamping inner-walls of duct, makes this shutoff train firmly be fixed in pipeline, and realizes sealing.Pressure in pipeline is different, can take the plugging device of varying number, form enough shutoff hermetic resistances.Utilize mechanics principle to be released by the pipeline pressure after train, make to form pressure difference before and after train, pipeline has the side of pressure to play a driving role to plugging device, and plugging device sealing effect is doubled.After having overhauled, by the pipeline boosting after train, by the time continue boosting again after pressure balance before and after train, make the pressure at pipeline rear portion higher than the pressure of pipeline front portion, allow the pressure after pipeline be applied on rubber ring and make the automatic deblocking of plugging device.After plugging device returns to original form, the pressure after reducing pipeline, utilizes pressure reduction shutoff train to be sent back to launching point taking-up and finishes the work.
Using method
First being sent to by shutoff train with transmitter needs in the pipeline location of shutoff, is then exerted pressure respectively 2 plugging device inside with automatic control device, forms locking device, then released by the pipeline pressure after train.Excision damages pipeline, reinstalls a new pipeline, pressurizes after installation to the pipeline after train, the follow-up pressure of continuing rising of pressure balance by the time before and after train.Now plugging device returns to original form, then reduces the pipeline pressure after train, by pipeline pressure reduction, shutoff train is pushed to former precalculated position, is finally taken out by train and namely completes service work.
Shutoff train is made up of wiper and plugging device, wherein wiper has two, the quantity of plugging device can increase by 2 to multiple, and be connected by hemisphere connecting rod between them, such Connecting format can allow wiper and plugging device move freely along inner-walls of duct; Be made up of multiple plugging device if middle, can be linked together by oil pipe between plugging device, by oil pipe, oil is injected into each plugging device inside.Wiper is generally connected with bolt by four pieces of sealing plates, and what wherein diameter was little is pilot seal plate; Four pieces of sealing plate both sides are made up of gland and chassis, has individual hemisphere groove in the middle of chassis, connects a hemisphere connecting rod above groove, and gland can play with the cooperation of hemisphere connecting rod and be connected free turning effect; Wiper inside is empty, and power plant and electric and automation equipment are installed in the inside.Intelligent plugging device is made up of supported flange, slips, wedge-like body, spring clip, rubber ring, base, sheave block.Supported flange is connected with supported flange collar bolt.Slips and wedge-like body adopt inclined design that slips is expanded and clamp inner-walls of duct; The effect of spring clip is to control sealing rubber ring distortion, allows rubber ring only be out of shape to side; Base and plugging device inner cylinder cap, cylinder barrel and piston form hydraulic jack, supported flange snap ring to be pressed on supported flange and to be stuck in the groove of piston one end, supported flange is maintained static, has key block at the sidewall of base, it effectively can control the amount of deformation of rubber ring; Plugging device is inner, and what be connected with supported flange is spring spool, and what be connected with base is screw rod, and being enclosed within, screw rod is spring.Screw rod has a leading role to prevent spring from pressing partially to spring.The effect of spring allows plugging device Self-unlocking recover original form.Rubber ring both sides are rubber hold-down rings, and its effect is that rubber is out of shape uniformly.Sheave block is evenly distributed on supported flange and base, and plugging device can be made like this to move in pipeline flexibly.
The utility model is relative to prior art, and tool has the following advantages:
The pipeline quick blocking train of this model utility, it is mainly used in the maintenance being laid on submerged pipeline and terrestrial pipeline.So just within the very first time, shutoff train can be delivered to scene and carry out repairing work.This pipeline quick blocking train solves when pipe first-aid without the deficiency of plugging device.This product plugging effect is tightly solid, has automatic control system and self-powered system, can well control its work in pipeline.Hemisphere between wiper and plugging device connects and adds that the sheave block of plugging device can move at pipe interior more flexibly and arrive specified position, and the pressure reduction in be the movement of plugging device the be tube road that illustrate realizes.Utilize shutoff train keep in repair pipeline time without the need to the medium in pipeline is all discharged, which save a large amount of resources.The plugging device of this product can be installed multiple, and the more plugging effects of quantity are better, and shutoff train in actual applications can Reusability.The pipeline scope that this shutoff train is suitable for is at 6 cun-48 cun, and pressure rating is within the scope of 2500LB.It is perfect that the utility model has delicate structure, diverse in function, and Automated condtrol performance is good; Use easy and simple to handle, save labor, location, shutoff, good seal performance, work efficiency is high, safety and environmental protection, solves a difficult problem for pipe plugging difficulty when a large amount of pipe-line maintenance is keeped in repair, has very high creativeness and practicability, and have very huge economic benefit.
