Detailed Description

Example 1

As shown in fig. 1-2, a gas detection alarm device comprises a sampling pipe 1 and an alarm 5 which are installed at a valve of a gas storage tank, and is characterized in that the sampling pipe 1 further comprises an annular gas production pipe 12 and a gas delivery pipe 13, one end of the gas delivery pipe 13 is communicated with the annular gas production pipe 12, the other end of the gas delivery pipe is provided with a gas suction pump 4, the annular gas production pipe 12 is provided with a gas production hole 11 for collecting gas, and the gas suction pump 4 is connected with the alarm 5 through a pipeline.

When the gas of storing in the gas holder is perfluor hexanone, the one end level that sampling pipe 1 is close to the gas holder valve sets up the valve department at the gas holder, and sampling pipe 1 is by adopting gas hole 11, annular gas production pipe 12 and gas-supply pipe 13 are constituteed, gas hole 11 has six and evenly sets up on the inner circle lateral wall of annular gas production pipe 12, gas hole 11 is circular and the opening direction all towards the valve position of gas holder, all be provided with corresponding filter screen in each gas production hole 11 department, and then filter impurity, avoid impurity entering to cause the device to damage.

When the quantity of gas holder is two, sampling pipe 1 is two with corresponding setting, at this moment, gas-supply pipe 13 also has two, it passes through collector pipe 3 and connects aspirator pump 4, and in gas-supply pipe 13 is connected with collector pipe 3, it is that the joint 31 that corresponds the setting in gas-supply pipe 13 and the collector pipe 3 is connected, consequently when the quantity of gas-supply pipe 13 is two, the quantity of joint 31 also is two, after the connection, aspirator pump 4 will gather gas and unified pass through the pipeline and transmit alarm 5 in, carry out relevant processing and warning to gas in alarm 5.

The principle of the device is as follows: the air suction pump 4 starts to work first, then the annular gas production pipe 12 collects gas at a valve through the gas production hole 11, the collected gas is transmitted into the collecting pipe 3 through the gas transmission pipe 13, then the gas is uniformly transmitted into the air suction pump 4, then the gas is transmitted into the alarm 5 through a pipeline, the alarm 5 comprises a voltage ionization terminal, when the collected gas contains perfluorohexanone, the voltage can change due to the concentration and is converted into concentration information and a leakage alarm signal, the signal sends the leakage alarm information to a user and a manager (a user end) through a 4G signal module (an electrically connected wireless communication module) and alarms in a communication connection mode, the alarm 5 can set a concentration threshold, when the concentration of the perfluorohexanone in the collected gas is higher than the threshold, the connected exhaust fan is triggered to work, the perfluorohexanone concentration of the environment where the gas storage tank is located is reduced, and the safety of personnel is guaranteed.

Through carrying out real-time gas acquisition to gas holder valve department, when gas leakage, be exactly that the volume of gas leakage is not many, equally can in time gather to in time make the leakage warning through the gas detection alarm ware, make the staff can be the most timely obtain alarm information, can the quickest make corresponding reaction, in order to ensure personal safety and reduce the loss of the gaseous of storage.

Example 2

This example differs from example 1 in that: a flow rate adjustment display valve 2 is connected to a position near the connection of the gas pipe 13 and the joint 31, as shown in FIG. 2.

This flow rate regulation display valve 2 can adjust the velocity of flow of the gas that annular gas production pipe 12 gathered, makes it in effectual within range to the gaseous velocity of flow size of digital display, the operating personnel of being convenient for handle as required, and when the velocity of flow was too big, alarm 5 also can send the too big warning of velocity of flow, and the staff of being convenient for carries out relevant processing.

Example 3

As shown in fig. 3, the present embodiment is different from embodiment 1 in that: the number of the gas storage tanks is 3, and the number of the corresponding sampling pipes 1 is three.

In practical application, there may be more than one gas storage tank for storing gas, and a plurality of gas storage tanks are provided, so that common collection can be realized by arranging a plurality of corresponding sampling pipes 1, and the practicability is improved.

The above description is only for the specific embodiment of the present invention, but the technical features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
