The plugging device solves the defects in the prior art that gas stopping and pressure reduction treatment can not be carried out immediately, the first valve of the drainer can not be processed in time, operation is reduced, gas leakage is more serious, and the like. In the plugging device for on-line replacement of the first valve of the metallurgy gas pipe drainer, the lower end of a feed screw (1) is connected with a taper plug (2), a nut (3) and a handle (4) are installed on the feed screw (1) on the upper portion of the taper plug (2) in turn, the nut (3) is connected with the handle (4), a T-shaped external pipe (5) is connected close to the nut (3) on the feed screw (1) on the lower portion of the nut (3), and the taper plug (2) is installed on the T-shaped external pipe (5). The plugging device can work without taking voltage directly in the whole process, thereby guaranteeing operation safety, and the plugging device ca be repaired and replaced under the state of not lowering the gas pipeline pressure and not stopping gas, and does not affect production of other users on the gas pipeline which needs checking and repairing.
Description
Technical field
The utility model relates to the gas pipe hydathode, specifically belongs to a kind of low-pressure gas pipeline that is applicable to gas pressure less than 25kpa, and the dust flue diameter is not more than the leakage-baffling device of one valve of the online replacing of metallurgical coal tracheae hydathode of 200mm.
Background technique
Built on stilts the laying of the general employing of metallurgy industry gas pipe line is the continuous blow-down that guarantees gas condensed water, and the every interval 150-200m of gas pipe line need be provided with a gas condensed water hydathode.
Coal gas drainer operated by rotary motion twice valve, wherein the first road valve is very crucial, and in a single day valve damages, and the normal maintenance of hydathode just can't be carried out.In a single day coal gas drainer puts into operation, and its one valve just substantially unconditionally changed.
Break down for one valve of hydathode, processing method is as follows at present.
1, gas pipe line stop the supple of gas or steam or step-down after be with gas to change;
2,, also take band to compress under one valve of row and install valve additional one behind the stifled blind plate for the pipeline that can not stop the supple of gas or steam or can not step-down.
3, abolishing former hydathode behind the stifled blind plate under the two road valves, new hydathode is installed in perforate separately on gas pipe line.The deficiency that its processing method exists:
1, is subject to responsible consumer production on the coal gas person in charge or this pipeline, can not stops the supple of gas or steam immediately or the step-down processing, make one valve of hydathode can not get in time handling or causing economic loss to the associated user;
2, reduced pressure operation gas leakage is more serious, has very big danger, has potential safety hazard;
Though 3, this operation can solve the pipe drainage problem, but in the actual production, one valve damage often is accompanied by two road valves and can not normally closes tight, therefore, can not carry out the blind plate operation under the two road valves, make problem can not get thorough solution, and after this because old hydathode is left over dust flue and the 2 road valves of growing, easily cause ponding in the winter time and bursting by freezing forms new hidden danger.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of and can safely and in time carry out the replacing of one valve of gas pipe line, and coal gas does not leak hardly when not influencing other users' productions, one valve of replacing, the leakage-baffling device that is used for one valve of the online replacing of metallurgical coal tracheae hydathode of energy safety inspection.
Realize the technical measures of above-mentioned purpose:
Be used for the leakage-baffling device of one valve of the online replacing of metallurgical coal tracheae hydathode, it is: be connected with taper in the lower end of screw mandrel and stop up, stop up in taper on the screw mandrel on top screw and handle are housed successively, screw also is connected with handle; With the screw adjacency T shape externally connected pipe is arranged on the screw mandrel of screw bottom, taper is stopped up and is contained in the T shape externally connected pipe.
It is: taper is stopped up by the universal regulated device and is connected with the lower end of screw mandrel.
It is: the funnel that catchments on taper obstruction and the gas pipe is the shape that closely cooperates, and taper is stopped up and is contained in the funnel that catchments during maintenance.
It is: also with the gas pipe of the concentricity line of funnel that catchments on be connected and communicate the perforate valve is installed.
It is: taper is stopped up and is externally connected with sealing layer.
The utility model compared with prior art, advantage is as follows:
1) can in time recover all functions of the hydathode of piping design.
2), whole process direct Operating Pressure, guaranteed the safety of operation.
3), can not reduce gas pipe line pressure, under the state of the coal gas of not stopping transport and overhaul and change, not influence the production that to overhaul other users on the gas pipe line.

Embodiment
Be further described below in conjunction with accompanying drawing:
The leakage-baffling device structure that is used for one valve of the online replacing of metallurgical coal tracheae hydathode; Processing screw mandrel 1 be to be suitable for the needs of different coal gas calibers, and screw mandrel 1 also can be segmentation and adopts to be threaded and form; Connect taper in the lower end of screw mandrel 1 by universal regulated device 6 and stop up 2; The funnel that catchments on taper obstruction 2 and the gas pipe is the drive fit shape, and the diameter that 2 upper ends are stopped up in taper is 150 millimeters, and lower end diameter is 50 millimeters.For strengthen taper stop up 2 with the sealing of catchmenting between the funnel, promptly prevent gas leakage, be pasted with rubber sealant 8 in the periphery of taper obstruction 2.Be welded to connect handle 4 in the employing of the upper end of the screw 3 that processes, and by being threaded on the screw mandrel 1; Make long 300 millimeters T shape externally connected pipe 5, on T shape externally connected pipe 5, process attachment hole, the T shape externally connected pipe 5 made by on the screw mandrel 1 that is threaded in screw 3 lower ends, and is made taper stop up 2 to place in the T shape externally connected pipe 5; With the gas pipe of the concentricity line of funnel that catchments on be connected and communicate perforate valve 7 is installed, T shape externally connected pipe 5 is connected with perforate valve 7 by flange.
Working principle
At first open perforate valve 7, shaking handle 4 makes screw mandrel 1 drive taper to stop up 2 and fall to hydathode by perforate valve 7 and catchment in the funnel and obturage (T shape externally connected pipe 5 is not produced the dirt displacement) that closely cooperate, the valve of opening water discharge device is confirmed stopping up effect, after determining no gas leak phenomenon, carry out general band gas again and change valve operation one.
