Abstract
The invention provides a winter pipe network field construction leakage check method. According to the method, an electromagnetic steam generator is included and connected with a tested pipe network; the electromagnetic steam generator is connected with a water source, and water is continuously injected into the electromagnetic steam generator; the electromagnetic steam generator heats the injected water, and the water is vaporized into high-pressure water vapor; the high-pressure water vapor is continuously injected into the tested pipe network through a pipeline and stops being injected till the winter pipe network field construction leakage check work is finished; the outer wall condition of the pipe network is checked, and whether leakage exists on the pipe network or not is judged according to the outer wall condition of the pipe network; if water stains or frost are/is left on the outer wall of the pipe network, the part, with the water stains or frost, of the pipe network has the leakage problem; if no water stain or frost is left on the outer wall of the pipe network, the pipe network does not have the leakage problem; the electromagnetic steam generator is connected into the tested pipe network so that the situation that the pipe network is frozen when the winter field construction air temperature is below zero, and the accident of pipe network frost crack is caused can be avoided; and meanwhile, the problem that the check duration of hot water injection in the pipe network is short can be solved.
Description
Technical field
The present invention relates to the field of pipe network field construction leakage inspection method in a kind of winter。
Background technology
It is highly difficult that winter field construction small plastic pipe network suppresses leakage detection, common process is to access pressure testing pipe network water filling with high-pressure hydraulic pump, after reaching detection pressure, voltage stabilizing a period of time observes Pressure gauge has undamped, pipe network welding quality is detected with this, there are the quality problems such as ne-leakage, but this process is constructed in the winter time, temperature is lower than easily occurring pipe network to freeze time subzero, causes the accident of frost crack pipe, loses very big；In order to reduce the accident of frost crack pipe, on-the-spot workmen carries out pipe network perfusion after being heated by water again, prevent pipe network from freezing, frost crack pipe, but, in the process owing to field temperature is low, the hot water temperature being poured in pipe network quickly reduces, it is not enough to support to leakage detection end-of-job, brings very big obstruction to pipe network field construction leakage detection work in winter。
Summary of the invention
The present invention provide a kind of winter pipe network field construction leakage inspection method, it is therefore an objective to solve prior art problem, it is provided that safely, effectively, easy pipe network field construction leakage inspection method in winter。
The problem of this invention address that the technical scheme is that
One pipe network field construction leakage inspection method in winter, it is characterised in that having electromagnetism steam generator, electromagnetism steam generator is connected with test pipe network, including:
Step 1: electromagnetism steam generator is connected with water source, and to sustained water injection in electromagnetism steam generator；
Step 2: the water heating that electromagnetism steam generator will inject, and it is vaporized into high-pressure steam；
Step 3: by continual for high-pressure steam by pipeline inject test pipe network, until winter pipe network field construction leakage detection end-of-job；
Step 4: check the outer wall situation of pipe network, judge whether pipe network has seepage according to the outer wall situation of pipe network；
Step 4 comprises two kinds of situations when checking the outer wall of pipe network:
If a. the outer wall of pipe network leaves water stain or frost, then the pipe network of this part has the situation of seepage；
If b. the outer wall of pipe network does not leave water stain or frost, then pipe network does not have the situation of seepage。
It is provided with Pressure gauge between described electromagnetism steam generator and test pipe network。
Described electromagnetism steam generator is connected to pressure-air pump。。
Beneficial effects of the present invention: electromagnetism steam generator is accessed test pipe network and can avoid winter field construction temperature lower than occurring pipe network to freeze time subzero, cause the accident of pipe network bursting by freezing, it is also possible to the problem that in improving pipe network, the perfusion hot water detection persistent period is short。
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described。
One pipe network field construction leakage inspection method in winter, has electromagnetism steam generator, and electromagnetism steam generator is connected to pressure-air pump and test pipe network, is provided with Pressure gauge between electromagnetism steam generator and test pipe network, including:
Step 1: electromagnetism steam generator is connected with water source, and to sustained water injection in electromagnetism steam generator；
Step 2: the water heating that electromagnetism steam generator will inject, and it is vaporized into high-pressure steam；
Step 3: by continual for high-pressure steam by pipeline inject test pipe network, until winter pipe network field construction leakage detection end-of-job；
Step 4: check the outer wall situation of pipe network, judge whether pipe network has seepage according to the outer wall situation of pipe network；
Step 4 comprises two kinds of situations when checking the outer wall of pipe network:
If a. the outer wall of pipe network leaves water stain or frost, then the pipe network of this part has the situation of seepage；
If b. the outer wall of pipe network does not leave water stain or frost, then pipe network does not have the situation of seepage。
Electromagnetism steam generator accesses test pipe network can avoid winter field construction temperature lower than occurring pipe network to freeze time subzero, causes the accident of pipe network bursting by freezing, it is also possible to the problem that in improving pipe network, the perfusion hot water detection persistent period is short。
When carrying out the work of winter field pipe network leakage detection, continue to inject water in electromagnetism steam generator, the water heating that electromagnetism steam generator will inject, it is vaporized into high-pressure steam, under the mate-assist of pressure-air pump, high-pressure water vapor is injected test pipe network, and it is full of whole test pipe network, after the high-pressure steam entering test pipe network reaches the pressure of test, continue to keep a period of time, until winter pipe network field construction leakage detection end-of-job, in the process continuing to inject high-pressure water vapor, can variable interval check test pipe network outer wall whether stay water stain or frost, according to test pipe network outer wall whether have stay water stain or frost judge test pipe network whether have the situation of seepage to occur, thus judging whether this test pipe network exists small opening。
The method can effectively avoid the situation of test pipe network icing bursting by freezing, solves difficult the carrying out of winter field construction leakage detection work, and can guarantee that the detection quality that pipe network leakage detection works。
