Abstract
The utility model relates to a quick drainage leak stopper for stopping leakage of a fluid conveying pipeline, which is an improvement on the prior leak stopper. The improved dry powder injection valve comprises a drainage plugging mechanism, a drainage plugging head 4 and a tensioning mechanism, wherein the drainage plugging mechanism is improved in that a dry powder injection valve 7 is welded on a sealing plate 6 which is welded with an outer short pipe 3 and an inner short pipe 8 which are coaxially sleeved, and is opposite to an opening at the interlayer between the two short pipes 3 and 8, and a dry powder extinguisher 13 is matched, so that fire extinguishing dry powder is injected into the interlayer between the two short pipes 3 and 8 through the dry powder injection valve 7 when plugging operation is carried out. The utility model discloses fundamentally has solved potential unsafe hidden danger in the shutoff salvagees the operation, simple structure, and easy and simple to handle, and practical, save.
Description
Technical field
The utility model is a kind of quick drainage leak stopping device of fluid delivery tube pipeline leakage stopping, is the Jin that changes that Now is had technology.Relate to the pipe-line system technical field.
Background technique
Fluid-transporting tubing is in operation and has leakage for various reasons unavoidably, present leak stopping skill Intraoperative is quite ripe, and our company is exactly typical representative in zl01231818.3, zl03244663.2 band oil [gas] pressure sealing device of on September 24th, 2003 and on the October 13rd, 2004 of mandate successively.It has solved when on pipeline or its annex leak source being arranged, and the repairing to leak source is not executed in the compacting of stopping transportation band oil [gas] band, and easy, safe and reliable.But blemish in an otherwise perfect thing is to also have some hidden danger of safety, can accumulate flammable waste gas during welding in the interlayer between the short tube exactly inside and outside plugging device, and the spark ignition in the time of just might be soldered when the waste gas that accumulates increases threatens safety.
The model utility content
The purpose of this utility model be design a kind of in pipe plugging repairing safer drainage plugging device.
The same drainage plugging mechanism that also comprises of the utility model with prior art, drainage block head 4 and tensioning mechanism [seeing Fig. 1], shrouding 6 as the drainage plugging mechanism upwards is welded with drain valve 5, be welded with two-tube coaxial outer short tube 3 that is nested and interior short tube 8 downwards, the shape of a saddle that matches with blocking pipe is made in Two short tube lower end, on interior short tube 8 shapes of a saddle O-ring seal 2 is housed, outer short tube 3 welds on pipeline 1, two manual chain cards 12 by tensioning mechanism pass and are enclosed within on the pipeline 1 in the hole on two chain ears 9 outside the short tube 3 outside being fixed on, the drainage plugging mechanism is buckled in location, back on the leakage point, treat that outer short tube 3 is after the welding of the shutoff on the pipeline 1 is finished, close drain valve 5, Will block head 4 is placed on the shrouding 6 and sealing.Characteristics of the present utility model are one to annotate dry powder valve 7 being welded over against interlayer place punching between outer short tube 3 and the interior short tube 8 on the shrouding 6, when implementing the shutoff operation by annotating interlayer injection fire-fighting powder between dry powder valve 7 outside short tubes 3 and the interior short tube 8.The fire-fighting powder here is to be docked with the import of annotating dry powder valve 7 and injected by powder-type fire extinguisher 13.Powder-type fire extinguisher 13 can be selected normally used various model powder-type fire extinguisher for use.

Embodiment
Embodiment: embodiment of the present utility model is described with this embodiment.The device of this example constitutes as shown in Figure 1, is stolen valve leak source on the diameter 508mm pipeline 10 is implemented shutoff the pressure As 5MPa of this place, stolen valve diameter 100mm, high 300mm.So interior short tube 8 selects the short tube of external diameter 200mm, high 400mm, wall thickness 10mm, outer short tube 3 selects the short tube of external diameter 400mm, high 410mm, wall thickness 10mm, the shape of a saddle supporting with pipeline made in two short tubes, 8,3 lower ends, shrouding 6 welding of O-ring seal 2, two short tubes 8,3 coaxial be nested upper end, back and diameter 400mm, thick 10mm are installed on the interior short tube 8 lower end shape of a saddle mouths; At the middle part of shrouding 6 perforate welding drain valve 5, model is the ball valve of DN25PN25, is welded over against outer short tube 3 and the punching of interior short tube 8 Zhi Inter Clip layer place at shrouding 6 and one annotates dry powder valve 7, and it selects for use model identical with drain valve 5; Block head 4 is bowl-shape, and the rim of a bowl external diameter is identical with the external diameter of outer short tube 3; The position at shape of a saddle middle part, corresponding lower end, short tube 3 outer tops is welded a chain ear 9 on one side outside, and it is cut into 100 * 150mm rectangular plate by the thick steel plate of 20mm, and the hole of diameter 10mm is beaten at its middle part, or is cut into a Ge half Round mouth at the rectangular plate middle part; Manual chain card 12 that adapted Two bar is commonly used again and powder-type fire extinguisher one tool commonly used.During the shutoff operation, connect drainage tube earlier and open drain valve 5, plugging device is buckled on the stolen valve leak source 10, tightly be positioned on the pipeline 1 with two manual chain cards 12, open and annotate dry powder valve 7, outer short tube 3 is welded with pipeline 1, simultaneously with the show loving care for import spray powder of dry powder valve 7 of 13 pairs of powder-type fire extinguishers, weld the capable reinforcing plate welding of reinforcing plate 11 Jin again according to welding process requirement such as need, stop spray powder after to be welded the finishing, close drain valve 5 and annotate dry powder valve 7, welding drainage block head 4 on the drainage sealing mechanism, Will Two valve seal is in the drainage plugging mechanism.When adopting this plugging device to weld, owing to spray fire-fighting powder in the interlayer between inside and outside short tube 8,3, weld in the outer short tube 3 Time Zai Clip layers the fire-retardant gas that produces by dry powder and cut off contacting of inflammable gas and naked light, certainly also Jiu Du Absolutely the possibility that fires of combustible gas, thereby can guarantee being perfectly safe in the welding process.This device has also proved this point fully through test of many times and on-the-spot actual the use.
As from the foregoing, the utility model has only been done a place to existing plugging device and has been changed and just thoroughly to have solved potential hidden danger in the shutoff repairing, and structure is very simple, operate also very easy, also practical, saving.
