Abstract
The invention discloses foam leakage detection equipment for a heat exchanger. The foam leakage detection equipment comprises an air compressor and a foaming device, wherein the air compressor and the foaming device are connected through a pipeline. The foaming device comprises a reactor, a regulating valve, a packing valve, a water drain valve and a discharge valve. The reactor is of a tank-shaped structure used for generating foam, the regulating valve is located on one side of the rector and connected with the air compressor, the packing valve is located on the top of the reactor, the water drain valve is located at the bottom of the reactor, and the discharge valve is located on the other side of the reactor. The foam leakage detection equipment has the advantages of being simple in structure, convenient to move, and capable of being used for detecting leakage of multiple heat exchange pipes at the same time.
Description
Technical field
This invention relates to a kind of leakage detection apparatus, particularly a kind of foam leakage detecting device for heat interchanger.
Background technology
At present, the leak test of the heat exchanger tube of plant condenser and other all tubular heat exchangers is a large technical barrier that perplexs for a long time power plant always.Originally traditional use film, candle, U-shaped pressure reduction pipe, defectoscope, setting-out such as look for leakage at the drawback existing, and can not find rapidly, exactly leak source and fistulae.Have at present part inventor also to invent some devices that utilize foam to hunt leak, but these apparatus structures are complicated and to examine several heat exchanger tubes, have the inefficient problem of leak detection only simultaneously.
Summary of the invention
1, need the technical matters of solution
The object of this invention is to provide a kind of simple in structure and can be simultaneously for the portable foam leakage detection apparatus of many heat exchanger tubes leak detections.
2, technical scheme
A kind of foam leakage detecting device for heat interchanger, comprise the air compressor and the foam device that by pipeline, connect, described foam device comprises reactor, variable valve, filler valve, water drain valve and outlet valve, described reactor is the tank shape structure for generation of foam, the side that described variable valve is positioned at reactor is connected with air compressor, described filler valve is positioned at reactor head, and described water drain valve is positioned at reactor lower curtate, and described outlet valve is positioned at reactor opposite side.Described variable valve is for regulating the air pressure of inside reactor so that produce satisfactory foam and be convenient to the tube wall that foam is sprayed at heat exchanger tube more equably.Described filler valve is for adding the material that produces foam.Water drain valve is for discharging unnecessary water and not using this leakage detection apparatus to discharge unnecessary material.Outlet valve is used for discharging satisfactory foam, can be in the exit of outlet valve connecting hose to increase scope of work.The leak-checking agent show bubble of crossing through reactor for treatment.During use, first this foam leak-checking agent is sprayed on the tube sheet of condenser, then with rubber board, strike off, make tube sheet and the mouth of pipe form even, abundant, the fine and smooth froth bed of one deck.Under the condition of negative pressure of condenser inside, can hunt leak.The standard of judgement is: if while having leakage on pipe port place or tube wall, with the naked eye just can be observed this place's froth bed and cave inward.
In order to monitor out the state of reactor, described foam device also comprises tensimeter and thermometer.
For the ease of this leakage detection apparatus, many heat exchanger tubes are hunted leak, the air compressor of described foam leakage detecting device can at least two foam devices of parallel connection simultaneously.
3, beneficial effect
Compared with prior art, its remarkable advantage is in the present invention: 1, simple in structure, and conveniently moving; 2, can be simultaneously for the leak detection of many heat exchanger tubes.
accompanying drawing explanation
Fig. 1 is control principle drawing of the present invention
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of foam leakage detecting device for heat interchanger, comprise the air compressor 1 and the foam device 2 that by pipeline, connect, described foam device 2 comprises reactor 21, variable valve 22, filler valve 23, water drain valve 24 and outlet valve 25, described reactor 21 is the tank shape structures for generation of foam, the side that described variable valve 22 is positioned at reactor 21 is connected with air compressor 1, described filler valve 23 is positioned at reactor 21 tops, described water drain valve 24 is positioned at reactor 21 lower curtates, and described outlet valve 25 is positioned at reactor 21 opposite sides.Described variable valve 22 for regulating the air pressure of reactor 21 inside so that produce satisfactory foam and be convenient to the tube wall that foam is sprayed at heat exchanger tube more equably.Described filler valve 23 is for adding the material that produces foam.Water drain valve 24 is for discharging unnecessary water and not using this leakage detection apparatus to discharge unnecessary material.Outlet valve 25, can be in the exit of outlet valve 25 connecting hose to increase scope of work for discharging satisfactory foam.The leak-checking agent show bubble of processing through reactor 21.During use, first this foam leak-checking agent is sprayed on the tube sheet of condenser, then with rubber board, strike off, make tube sheet and the mouth of pipe form even, abundant, the fine and smooth froth bed of one deck.Under the condition of negative pressure of condenser inside, can hunt leak.The standard of judgement is: if while having leakage on pipe port place or tube wall, with the naked eye just can be observed this place's froth bed and cave inward.In order to monitor out the state of reactor 21, described foam device also comprises tensimeter 26 and thermometer 27, and described thermometer 27 is temperature thermocouple.For the ease of this leakage detection apparatus, many heat exchanger tubes are hunted leak, the air compressor 1 of described foam leakage detecting device can at least two foam devices of parallel connection 2 simultaneously.
