Abstract

The utility model relates to an online repair device for gas leakage of a gas pipeline, belonging to the technical field of pipeline maintenance and comprising a plugging plate, a valve, a gas guiding pipe and a support, wherein one end of the plugging plate can be adaptively attached on the outer wall of the gas pipeline, and the other end of the plugging plate can be coupled with one end of the valve by a first flange; the other end of the valve is coupled with one end of the gas guiding pipe by a second flange; the other end of the gas guiding pipe is externally connected with an air exhaust device; and when the online repair device is used, the two ends of the support abuts against on a terrace and the gas guiding pipe respectively. The device designs a structure which mainly comprises the plugging plate, the valve and the gas guiding pipe, and is convenient and simple in manufacture; and safe welding is carried out on the plugging plate by guiding gas to a distant place from leaking points, so that fast online repair to gas-leaking points of the gas pipeline is realized.

Description

The gas pipe line online repairing apparatus that leaks gas
Technical field
The utility model relates to a kind of device of Repairing of Gas, belongs to the pipe-line maintenance technical field.
Background technique
Existing repairing technique at gas pipe line gas leakage has a lot, but all is coal gas will be cut off to repair or change pipeline usually, and this technology not only cost and is cut off coal gas and brought certain negative effect to the production of enterprise than higher.There are some to realize the online repairing of band coal gas by designing special device, Chinese patent as application number 200920187693.4 discloses a kind of gas pipe line expansion joint repairing apparatus, this device is located at seal closure the expansion joint position of gas pipe line, purge displacement by input steam in seal closure, realize the repairing of gas pipe line gas leakage point.But the seal closure complex structure of this device, make trouble, and need to feed steam and weld, energy consumption is big, welding inconvenience.
The model utility content
The technical problems to be solved in the utility model is, propose a kind of simple in structure, make device convenient and can online quick repairing gas pipe line gas leakage.
The technical solution of the utility model is: a kind of gas pipe line online repairing apparatus that leaks gas, comprise that an end can abut in shutoff plate, valve, air entraining pipe and the support on the gas pipe line outer wall with adapting to, the other end of described shutoff plate connects an end of valve by first flange, the other end of described valve is by an end of second flange connection air entraining pipe, the external extractor fan of the other end of described air entraining pipe; During use, the two ends of described support are against respectively on terrace and the air entraining pipe.
During use, elder generation aims at gas leakage point with an end of shutoff plate and abuts near the gas pipe line outer wall of gas leakage point, the other end at the shutoff plate passes through the first flange mounted valve, on valve, air entraining pipe is installed with second flange, the external extractor fan of the other end of air entraining pipe (as blower fan) will support two ends and be against respectively on terrace and the air entraining pipe; Seam between shutoff plate and the gas pipe line outer wall is sealed from the gas leakage point with clay then, start extractor fan and open valve,--valve--bleed pipeline deflects from a distance from the leak point along the shutoff plate with coal gas; Near shutoff plate and gas pipe line outer wall seam, no longer include any coal gas this moment and exist, carry out reinforcement of weld along shutoff plate and gas pipe line outer wall seam crossing rapidly; Welding finishes, throttle down, removal air entraining pipe.Like this, just finish online repairing to the gas pipe line leak point.
The gas pipe line of the present utility model beneficial effect that online repairing apparatus compares existing Repairing of Gas device that leaks gas is: designed the convenient and simple structure of making that mainly is made of shutoff plate, valve and air entraining pipe, by coal gas being deflected from from the leak point at a distance the shutoff plate is carried out safe welding, thereby realize quick online repairing gas pipe line gas leakage point.
The perfect of technique scheme is: also be provided with clip on the described shutoff plate.
Further improving of technique scheme is: an end flare of described shutoff plate, and described extractor fan is an induced draught fan, described support is a column.
Description of drawings
Below in conjunction with accompanying drawing the gas pipe line of the present utility model online repairing apparatus that leaks gas is described further.
Fig. 1 is the utility model embodiment one the gas pipe line online repairing apparatus structural representation that leaks gas.
Fig. 2 is the utility model embodiment two the gas pipe line online repairing apparatus structural representation that leaks gas.
Embodiment
Embodiment one
The gas pipe line of present embodiment leaks gas online repairing apparatus as shown in Figure 1, comprises that an end can abut in shutoff plate 1, valve 2, the air entraining pipe 3 on the gas pipe line outer wall with adapting to and support 4.One end flare of shutoff plate 1, its other end connect an end of valve 2 by first flange 5; The other end of valve 2 connects an end of air entraining pipe 3 by second flange 6; The external extractor fan of the other end of air entraining pipe 3.
The extractor fan of present embodiment adopts induced draught fan, supports 4 and adopts column.
In use, as shown in Figure 1, the two ends of supporting 4 are against respectively on terrace and the air entraining pipe 3, the concrete use condition of present embodiment is seen before and is stated the model utility content.
Embodiment two
The gas pipe line of present embodiment leaks gas online repairing apparatus as shown in Figure 2, and basic identical with embodiment one, different is: also be provided with clip 7 on shutoff plate 1.Like this, in use, except with clay with between shutoff plate 1 and the gas pipe line outer wall sealing, also can shutoff plate 1 be pressed and lean against on the gas pipe line outer wall by clip 7, thereby improve the sealing between shutoff plate 1 and the gas pipe line outer wall, help the Security when shutoff plate 1 and gas pipe line outer wall welded.
The gas pipe line of the present utility model online repairing apparatus that leaks gas is not limited to the various embodiments described above, such as: 1) end of shutoff plate 1 also can be made other shapes, abuts on the gas pipe line outer wall to adapt to shutoff plate 1; 2) support 4 and also can adopt support or other supporting forms; 3) extractor fan also can adopt fan or other extractor fans.All employings are equal to replaces the technological scheme that forms, and all drops on the protection domain of the utility model requirement.
