Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, fig. 2, fig. 3 and fig. 4, an externally-hung gas leakage monitoring system for a gas meter includes: an air inlet flow velocity measuring pipe, an air outlet flow velocity measuring pipe, a power supply module 4 and a control module 9. The power module 4 is arranged on the air inlet flow speed measuring pipe and is fixedly connected with the air inlet flow speed measuring pipe. The control module 9 is arranged on the air inlet flow velocity measuring pipe and is electrically connected with the air inlet flow velocity measuring pipe and the air outlet flow velocity measuring pipe.
The air inlet flow rate measuring tube is arranged on an air inlet pipe of the gas meter and is detachably connected with the gas meter. The intake flow rate measurement pipe includes: the air inlet outer pipe body 1, the air inlet inner pipe body 2, the first pressure sensor 3 and the second pressure sensor 8. One end of the air inlet outer pipe body 1 is connected with an air inlet pipe orifice of the gas meter, and the other end of the air inlet outer pipe body is connected with a gas pipeline. The first pressure sensor 3 is installed at one end inside the air inlet outer tube body 1 and is electrically connected with the control module 9. The inner air inlet pipe 2 is arranged in the outer air inlet pipe 1, one end of the inner air inlet pipe 2 is abutted to the end of the inner air inlet pipe 2, and the other end of the inner air inlet pipe is abutted to the first pressure sensor 3. The electromagnetic valve 10 is arranged at one end of the air inlet outer pipe body 1 connected with the gas pipeline and is electrically connected with the control module 9.
The gas outlet flow velocity measuring tube is arranged on the gas outlet tube of the gas meter and is detachably connected with the gas meter. The air outlet flow velocity measuring pipe comprises: an outer gas outlet pipe body 6, an inner gas outlet pipe body 7 and a second pressure sensor 8. One end of the gas outlet outer pipe body 6 is connected with a gas outlet pipe of the gas meter, and the other end of the gas outlet outer pipe body is connected with a gas supply pipeline. The second pressure sensor 8 is installed at one end inside the outer gas outlet pipe body 6 and is electrically connected with the control module 9. The inner gas outlet pipe 7 is arranged in the outer gas outlet pipe 6, one end of the inner gas outlet pipe abuts against the end of the outer gas outlet pipe 6, and the other end of the inner gas outlet pipe abuts against the second pressure sensor 8.
The inner walls of the air outlet inner pipe body 7 and the air inlet inner pipe body 2 are both provided with stress sheets 5, and one end of each stress sheet 5 is fixedly connected with the inner wall of the air outlet inner pipe body 7 or the air inlet inner pipe body 2. The stress sheets 5 are distributed at different heights on the inner wall of the inner gas outlet pipe 7 or the inner gas inlet pipe 2 in a staggered manner. And piezoelectric sensors are used as the first pressure sensor 3 and the second pressure sensor 8. The layered and staggered distribution of the stress pieces 5 can reduce the influence on gas conveying for collecting gas impact force as much as possible under the condition that the contact surface with gas can be increased as much as possible.
The utility model relates to an outer hanging gas leakage monitoring system to current gas table repacking judges through the velocity of flow of giving vent to anger to the inlet flow of gathering the intake pipe and the outlet flow of gas outlet pipe, judges whether the gas has taken place the loss through the gas table to this judges whether gas table takes place to leak gas. If the gas meter is judged to be leaked, the electromagnetic valve 10 is started to close the gas inlet pipeline, so that accidents are prevented.
In use, when gas is used, the gas in the whole pipeline can flow. Because the plurality of stress sheets 5 are arranged in the air outlet inner pipe body 7 and the air inlet inner pipe body 2, when the gas flows, the gas can impact the stress sheets 5, and the stress sheets 5 are fixed on the inner walls of the air outlet pipe inner body and the air inlet inner pipe body 2, so that the impact force of the gas on the stress sheets 5 can act on the air outlet inner pipe body 7 and the air inlet inner pipe body 2 finally. One end of the inner gas outlet pipe 7 abuts against the second pressure sensor 8, and one end of the inner gas inlet pipe 2 abuts against the first pressure sensor 3.
Therefore, for the gas meter with the gas inlet pipe and the gas outlet pipe both arranged at the top of the gas meter, when the gas meter is installed, the end of the gas inlet outer pipe body 1, which is provided with the first pressure sensor 3, is connected with the gas inlet pipe of the gas meter, and the end of the gas outlet outer pipe body 6, which is provided with the second pressure sensor 8, is connected with the gas outlet pipe of the gas. At this time, the pressure applied to the first pressure sensor 3 is the sum of the gravity of the intake inner pipe 2 and the force of the gas acting on the intake inner pipe 2. Because the gas flow direction is different in gas table intake pipe and the outlet duct in the gas, the pressure that second pressure sensor 8 received is the difference of the gravity of the interior body 7 of giving vent to anger and the effort of gas to interior body 7 of giving vent to anger.
For the gas meter with the gas inlet pipe and the gas outlet pipe both arranged at the top of the gas meter, when the gas meter is installed, the end of the gas inlet outer pipe body 1, which is not provided with the first pressure sensor 3, is connected with the gas inlet pipe of the gas meter, and the end of the gas outlet outer pipe body 6, which is not provided with the second pressure sensor 8, is connected with the gas outlet pipe of the gas. At this time, the pressure applied to the first pressure sensor 3 is the sum of the gravity of the intake inner pipe 2 and the force of the gas acting on the intake inner pipe 2. Because the gas flow direction is different in gas table intake pipe and the outlet duct in the gas, the pressure that second pressure sensor 8 received is the difference of the gravity of the interior body 7 of giving vent to anger and the effort of gas to interior body 7 of giving vent to anger.
Then the control module 9 calculates the values obtained by the first pressure sensor 3 and the second pressure sensor 8 to determine whether the gas is lost through the gas meter, and if the gas is lost through the gas meter, it is determined that the gas meter leaks. The control module 9 controls the electromagnetic valve 10 to be closed, so that the gas meter does not intake any more, and the gas meter is timely informed to a gas management center to request maintenance.
The conditions that the gas inlet pipe and the gas outlet pipe are arranged at other positions of the gas meter are not illustrated one by one, and the general idea is that the first pressure sensor 3 and the second pressure sensor 8 can monitor the acting force of the gas on the gas inlet inner pipe body 2 and the gas outlet inner pipe body 7, and the relation between the acting force of the gas on the gas inlet inner pipe body 2 and the acting force of the gas on the gas outlet inner pipe body 7 is calculated, so that the problem that whether the gas meter has gas leakage or not is solved. Therefore, the externally-hung air leakage monitoring system has extremely high compatibility and adaptability.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
