Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the utility model provides a water heater gas tightness detection device, as shown in figure 1, including first manometer 1, second manometer 2, gas flowmeter 3 and can provide compressed air's air pump 4, air pump 4 is through the air inlet 5 intercommunication of air inlet pipeline and water heater combustion chamber, and gas flowmeter 3 and first manometer 1 are installed on the air inlet pipeline, and second manometer 2 is installed in 6 departments of gas outlet of water heater collection petticoat pipe C.
By adopting the structure, after three large parts (the smoke collecting hood C, the heat exchanger B and the combustion chamber A) of the water heater to be detected are assembled, the three large parts are fixed on a bottom plate or a workbench, then the air pump 4 starts to introduce compressed air to the direction of the air inlet 5, and the compressed air sequentially passes through the first pressure gauge 1, the gas flowmeter 3 and the air inlet 5 in an air inlet pipeline and enters the three large parts of the water heater. Continuously introducing compressed air to stabilize the first pressure gauge 1 at a preset specified value; if the three major parts of the water heater have good air tightness, the introduced gas quantity is smaller, the measured value of the gas flowmeter 3 is smaller, and the difference value between the second pressure gauge 2 and the specified value is smaller; therefore, whether the air tightness of the water heater is qualified or not can be judged by observing whether the values of the second pressure gauge 2 and the gas flowmeter 3 are within the preset specified value range or not.
The embodiment of the utility model provides a still be equipped with cylinder 7 and end cap 8, cylinder 7 is used for shutoff air inlet 5, and end cap 8 is used for shutoff gas outlet 6. The cylinder 7 is communicated with the air inlet pipeline, and the plug 8 is connected with the second pressure gauge 2. After the air inlet 5 and the air outlet 6 are plugged, three large parts of the water heater form a relatively closed space, so that the measurement of the first pressure gauge 1 and the second pressure gauge 2 is facilitated.
The utility model discloses second manometer 2 is preferred to be "U" shape pressure gauge, can make the testing result more accurate and directly perceived.
The embodiment of the utility model provides a still include air pressure regulating valve 9, air pressure regulating valve 9 is installed on the intake pipeline. During the detection process, the pressure of the gas introduced into the three major parts of the water heater can be controlled by using the gas pressure regulating valve 9.
The gas inlet 5 is internally provided with a one-way valve (not shown), the gas flowmeter 3 is communicated with the one-way valve, and the one-way valve enables gas to be introduced into the three major parts of the water heater from the gas inlet 5 only through the gas flowmeter 3 and can not leak out of the water heater from the gas inlet 5.
The detection method and the process are as follows:
as shown in fig. 2, the three major components of the water heater to be detected are assembled and then fixed on a bottom plate or a workbench; the air inlet 5 is blocked by an air cylinder 7, the air outlet 6 is blocked by a plug 8, the air pump 4 starts to introduce compressed air, and then the compressed air sequentially passes through an air pressure regulating valve 9, a first pressure gauge 1, a gas flowmeter 3 and the air inlet 5 which are connected to an air inlet pipeline and enters the interior of the three parts of the water heater; the air pressure regulating valve 9 is regulated to enable the first pressure gauge 1 to reach a specified value, and because the inside of the three major parts of the water heater cannot be completely sealed, a small amount of gas inevitably leaks out, the internal air pressure is reduced, the first pressure gauge 1 can be stabilized at the specified value by continuously introducing compressed air, if the three major parts are good in air tightness, the leaked gas is small, the introduced gas amount is small, and the measured value of the second pressure gauge 2 at the air outlet 6 cannot be reduced too fast; and finally, observing whether the measured values of the second pressure gauge 2 and the gas flowmeter 3 are within a preset specified value range, wherein if the measured values are within the specified value range, the air tightness of the three major parts of the water heater is qualified, and otherwise, the measured values are unqualified.
