Abstract
The utility model relates to a multidirectional leak detector comprising a pressure gauge, a multi-way tube, and a plurality of check valves. The multi-way tube is provided with n interfaces, and the number of the check valves is n-1. One interface of the multi-way tube is connected with the pressure gauge, and the rest of the interfaces are respectively connected with the check valves. By using the leak detector, the leak detection of civil gas meters, gas cookers, and gas heaters can be completed once, the process is simple, the detection time is short, and the working efficiency is high.
Description
Technical field
The utility model relates to a kind of multidirectional leak detector.
Background technology
In routine duties, safety is first, and especially for displacement (air-discharging the changes into rock gas) maintenance man of domestic gas pipeline, device, they are last passes of whole domestic gas table replacement process.At present, the maintenance man tests the pressure condition of kitchen range or water heater or gas meter, flow meter with tensimeter, carry out safe leak detection.The shortcoming of existing this technology is: can only in gas meter, flow meter, kitchen range or water heater be hunted leak, program is loaded down with trivial details, length consuming time, inefficiency at every turn.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of leak detector, uses this leak detector can realize the leak detection work of domestic gas table, gas kitchen ranges, gas heater etc. is once completed, high efficiency.
In order to solve the problems of the technologies described above, the utility model provides a kind of multidirectional leak detector, comprise tensimeter, also comprise siphunculus more than, some retaining valves, the interface of many siphunculus is n, the quantity of retaining valve is that (n-1) is individual, and interface of many siphunculus and tensimeter join, remain interface and join with each retaining valve respectively.
During use, the connecting hose of the gas meter, flow meter that needs are hunted leak, gas kitchen ranges, gas heater etc. respectively with multidirectional leak detector on retaining valve join, can hunt leak to many places such as gas meter, flow meter, gas kitchen ranges, gas heaters simultaneously by tensimeter: normal if tensimeter shows, gas meter, flow meter, gas kitchen ranges, gas heater etc. all do not have gas leak phenomenon; If it is undesired that tensimeter shows, detect the gas equipment of concrete gas leakage by controlling retaining valve on multidirectional leak detector, thus next flow process of F.F. line replacement maintenance job very.
Therefore, use this leak detector can realize the leak detection work of domestic gas table, gas kitchen ranges, gas heater etc. is once completed, program is simple, short, high efficiency consuming time.
As further optimization of the present utility model, the interface of described many siphunculus is 4, and the quantity of retaining valve is 3.
At present, the aeration equipment that needs in most of families to hunt leak mainly contains gas meter, flow meter, gas kitchen ranges, gas heater, therefore, prioritization scheme of the present utility model is for adopting four-way piece, like this, and after a joint of tensimeter and four-way piece is joined, remaining three joints of four-way piece are joined with retaining valve respectively, when needs are hunted leak, with the connecting hose of gas meter, flow meter, gas kitchen ranges, gas heater respectively with multidirectional leak detector on each retaining valve join, can carry out leak detection work.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Referring to Fig. 1, multidirectional leak detector comprises a tensimeter 1, four-way piece 2, retaining valve 31, retaining valve 32, retaining valve 33, and interface of four-way piece 2 and tensimeter 1 join, remain interface and join with retaining valve 31, retaining valve 32, retaining valve 33 respectively.
When using multidirectional leak detector to hunt leak, connecting hose and the retaining valve 31 of gas kitchen ranges can be joined, connecting hose and the retaining valve 32 of gas heater join, outlet side flexible pipe and the retaining valve 33 of gas meter, flow meter join, can hunt leak by tensimeter 1 pair of gas meter, flow meter, gas kitchen ranges, gas heater.
Leak detection step: open the front valve (controlling the main valve of each family air inlet) of table of gas meter, flow meter, make and show front valve ventilation, when tensimeter 1 shows that pressure reaches 5000 MPa, close and show front valve, stop air inlet.Close before table after valve, if tensimeter 1 still show normally, illustrate that gas meter, flow meter, gas kitchen ranges, gas heater etc. all do not have air leak position; If tensimeter 1 shows pressure drop, the switching of controlling each retaining valve by controlling handle a on retaining valve detects air leak position, be specially: closing one-way valve 31, if this moment, the pressure of tensimeter 1 demonstration no longer descended, illustrate that the gas kitchen ranges that joins with retaining valve 31 partly has air leak position; If this moment, the pressure of tensimeter 1 demonstration still descended, closing one-way valve 32 again: the pressure of tensimeter 1 demonstration no longer descends as this moment, open retaining valve 31, the pressure that shows as tensimeter 1 still no longer descends again, and explanation is that the gas heater that is connected with retaining valve 32 partly has air leak position; After closing one-way valve 31, retaining valve 32, the pressure that tensimeter 1 shows still descends, then closing one-way valve 33, as this moment pressure no longer descend, explanation is that before table, the later gas meter, flow meter of valve partly has air leak position; Still descend if three retaining valves are all closed the pressure that rear tensimeter 1 shows, illustrate that tensimeter 1 part has gas leakage.
In sum, utilize described multidirectional leak detector can fast detecting to provide the gas equipment of body drain gas, thus next flow process of F.F. line replacement maintenance job very.Described multidirectional leak detector is simple in structure, easy to carry, and testing result is accurate, short, high efficiency consuming time.
