阅读说明：本技术 一种管道补漏方法 (A kind of blocking Leakage method ) 是由 陈科 李圭文 高文东 夏平 杨永俊 谭贤会 蓝伯洋 刘高鑫 方家悦 彭耀光 于 2018-07-18 设计创作，主要内容包括：本发明涉及一种管道补漏方法,其补漏步骤是：先制作一个用于焊接于管道穿漏的密封管,密封管的一端准备焊接在穿漏的故障管道上,所以密封管的这一端与穿漏的管道的外表面要配合紧密便于焊接,密封管的另一端与阀门相连接；阀门开启,将密封管没装阀门的一端贴近穿漏的管道,穿漏点处于密封管道的内腔中,由于阀门处于开启状态,密封管内的压力接近于大气压,便于焊接；将密封管与穿漏管道之间的对接缝焊接起来,焊接质量满足密封要求；关闭阀门。能够在管道不停止使用的情况下,对管道穿漏点进行维修处理,方法简单实用。(The present invention relates to a kind of blocking Leakage methods, its leak repairing step is: first making one for being welded in the seal pipe of pipeline leakage, one end of seal pipe prepares to be welded on the failure pipeline of leakage, so the outer surface of the pipeline of this one end and leakage of seal pipe will cooperate closely convenient for welding, the other end of seal pipe is connected with valve；Seal pipe the one end for not filling valve close to the pipeline of leakage by valve opening, and leakage point is in the inner cavity of sealing pipeline, and since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；Abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；Close valve.Maintenance process, method simple practical can be carried out to pipeline leakage point in the case where pipeline is not stopped using.)

1. a kind of blocking Leakage method, it is characterised in that leak repairing step is:

(1) one is first made for being welded in the seal pipe of pipeline leakage, and one end of seal pipe prepares the failure for being welded on leakage On pipeline, thus the outer surface of the pipeline of this one end and leakage of seal pipe to cooperate it is close convenient for welding, seal pipe it is another End is connected with valve；

(2) seal pipe, the pipeline for not filling one end of valve close to leakage by valve opening, and leakage point is in the inner cavity of sealing pipeline In, since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；

(3) abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；

(4) valve is closed.

2. blocking Leakage method as described in claim 1, it is characterised in that: the first step has first been made before welding leak repairing At.

Technical field

The invention belongs to leakage mending technique fields, are related to a kind of blocking Leakage method.

Background technique

Pipeline is widely used in industrial production, and pipeline is in use because a variety of causes is it is possible that leakage.Usually After pipeline leakage occurs, after stopping pipeline use, replacement or repairing pipeline.If stopping pipeline wearing using processing pipeline Leakage can have an impact to production, some possible situations cause serious economic loss.There are more leakage pipeline needs using Leak stopping is carried out in journey.

Summary of the invention

In order to overcome the disadvantages mentioned above of the prior art, the present invention provides a kind of blocking Leakage method, it can pipeline not In the case where stopping using, maintenance process, method simple practical are carried out to pipeline leakage point.

The technical solution adopted by the present invention to solve the technical problems is: a kind of blocking Leakage method, leak repairing step is:

1. first making one for being welded in the seal pipe of pipeline leakage, one end of seal pipe prepares the failure pipe for being welded on leakage On road, so the outer surface of the pipeline of this one end and leakage of seal pipe will cooperate close convenient for welding, the other end of seal pipe It is connected with valve；

2. seal pipe, the pipeline for not filling one end of valve close to leakage by valve opening, leakage point is in the inner cavity of sealing pipeline In, since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；

3. the abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；

4. closing valve.

The first step is first completed before welding leak repairing.

The positive effect of the present invention is: in the state of not stopping conduit running, can carry out pipeline welding leak repairing, difficulty It is smaller, there is very much practicability.

Detailed description of the invention

Fig. 1 is 1 structural schematic diagram of embodiment；

Fig. 2 is another embodiment schematic diagram.

In figure: 1- pipeline, 2- leakage point, the big seal pipe of 3-, 4- flange, 5- gasket, 6- screw bolt and nut, 7- steel plate, The small seal pipe of 8-, 9- valve.

Specific embodiment

The present invention is further described with reference to the accompanying drawings and embodiments.

Referring to Fig. 1 and Fig. 2, a kind of blocking Leakage method, leak repairing step is:

1. first making one for being welded in the seal pipe of pipeline leakage, one end of seal pipe prepares the failure pipe for being welded on leakage On road, so the outer surface of the pipeline of this one end and leakage of seal pipe will cooperate close convenient for welding, the other end of seal pipe It is connected with valve；

2. seal pipe, the pipeline for not filling one end of valve close to leakage by valve opening, leakage point is in the inner cavity of sealing pipeline In, since valve is in the open state, the pressure in seal pipe is close to atmospheric pressure, convenient for welding；

3. the abutment joint between seal pipe and leakage pipeline is welded, welding quality meets seal request；

4. closing valve.

The first step is first completed before welding leak repairing.
