[0004] Although the above flame arrester has achieved a wide range of explosion-proof applications, small fluid resistance, simple structure, low cost, can prevent explosion flames, and is easy to replace and clean, it still has the problem that the flame arrester cannot monitor its own shell damage during use. If pressure loss occurs due to shell collapse, it is difficult to complete the fire-proof operation. Utility Model Content

[0005] In order to solve the problem that the flame arrester cannot monitor the damage of its own shell during use, the present application provides a flame arrester with a pressure loss detection function.

[0024] 1. The pressure loss protection balloon is used to protect the outside of the flame arrester main cavity in conjunction with the pressure loss protection outer shell during use, and the pressure sensor monitors the pressure loss condition in real time. When the pressure sensor collides with the other end of the damping block, the pressure generated can indicate that the device has pressure loss and needs to be replaced or maintained, which can avoid the inconvenience caused by manual scheduled maintenance. At the same time, the pressure loss of the device can be monitored in real time, which improves the practicality and stability of the device.

[0025] 2. With the help of the heat conducting sheet, the temperature of the connected pipes is monitored through the heat transfer of the heat conducting sheet and the temperature sensor probe.

[0032] The embodiment of the present application discloses a flame arrester with a pressure loss detection function.

[0033] Example 1

[0034] like Figures 1 to 4 As shown, the utility model provides a flame arrester with a pressure loss detection function, including a pressure loss protection outer shell 1, a flame arrester main cavity 3 is arranged inside the pressure loss protection outer shell 1, and the outer side wall of the flame arrester main cavity 3 is fixedly connected with a pressure loss protection balloon 2 arranged with an inflatable structure, the outer side wall of the pressure loss protection balloon 2 is fixedly connected to the inner side wall of the pressure loss protection outer shell 1, and four damping blocks 4 are fixedly connected to the inside of the pressure loss protection balloon 2 at equal intervals, and one end of the inside of the four damping blocks 4 is fixedly connected with a pressure sensor 5, and the model of the pressure sensor 5 is BPR-AS.

[0035] By means of the provided pressure loss protection balloon 2, during use, the outside of the flame arrester main cavity 3 can be protected by the pressure loss protection balloon 2 in cooperation with the pressure loss protection outer shell 1, and the pressure loss condition can be monitored in real time by means of the damping block 4 provided inside the flame arrester main cavity 3 and the pressure sensor 5 fixedly connected to one end of the damping block 4. When the pressure sensor 5 collides with the other end of the damping block 4, the generated pressure can indicate that the device has pressure loss and needs to be replaced or maintained.

[0036] like Figure 1 and Figure 2 As shown, specifically, both ends of the flame arrester main cavity 3 are flange-connected with the flame arrester connecting cavity 6, and one end of the flame arrester connecting cavity 6 is flange-connected with a mounting pipe 8 covered on the outside of the connected pipeline through the flange of the first flange connecting plate 7, one end of the mounting pipe 8 is flange-connected with a connecting frame 10 through the flange of the second flange connecting plate 9, and one end of the connecting frame 10 is fixedly connected with a sealing cover 11, and one end of the sealing cover 11 is fixedly connected with an elastic cinch band 12.

[0037] By setting up the installation tube 8, the installation tube 8 cover is set on the outside of the connected pipe, and then the elastic cuff band 12 is sleeved on the outer wall of the connected pipe. In this way, the flange connection between the installation tube 8 and the first flange connection plate 7 is sealed for the second time through the sealing cover 11 and the elastic cuff band 12, thereby avoiding the outflow of smoke due to looseness or other reasons after a long time.

[0038] like Figures 1 to 3As shown, the inner wall of the mounting tube 8 is fixedly connected with a resistance balloon 13 having a circular ring structure, and the inner wall of the resistance balloon 13 is evenly penetrated and fixedly connected with a heat conductive sheet 14 having a copper structure, one end of the heat conductive sheet 14 is fixedly connected to the monitoring end of a temperature sensing probe 15 disposed inside the resistance balloon 13, and the other end of the temperature sensing probe 15 is fixedly connected to one end of a connecting balloon block 16, and the connecting balloon block 16 is evenly fixedly connected to the inner wall of one side of the resistance balloon 13.

[0039] By setting the resistance balloon 13, the heat conductive sheet 14 cooperates with the resistance balloon 13 to resist against the outer wall of the connected pipe during use, and then the temperature of the connected pipe is monitored by the heat transfer of the heat conductive sheet 14 and the temperature sensor probe 15. When a temperature abnormality occurs, the device can have a certain early warning function, so that the fire-blocking effect of the flame arrester main cavity 3 is better.

[0040] like Figure 1 As shown, the top of the flame arrester main cavity 3 is fixedly connected with an inspection port 17 penetrating the top of the pressure loss protection outer shell 1, and the top of the inspection port 17 is fixedly connected with a sealing cover plate 18 by screws;

[0041] Through the inspection port 17 , when it is necessary to maintain or overhaul the components inside the flame arrester main cavity 3 , the sealing cover plate 18 can be removed and then the components inside the flame arrester main cavity 3 can be maintained or overhauled through the inspection port 17 .

[0042] Principle and process of this utility model:

[0043] Firstly, flange connections are made to the pipes to be connected through the first flange connection plate 7, so that the mounting tube 8 cover is arranged outside the connected pipe, and the elastic cuff band 12 is connected to the outer wall of the connected pipe. After the connection, the flange connection between the mounting tube 8 and the first flange connection plate 7 is secondary sealed through the sealing cover 11 and the elastic cuff band 12. Afterwards, in daily use, the pressure loss protection balloon 2 can be used in cooperation with the pressure loss protection outer shell 1 to protect the outside of the flame arrester main cavity 3, and the pressure loss condition can be monitored in real time through the damping block 4 arranged inside the flame arrester main cavity 3 and the pressure sensor 5 fixedly connected to one end of the damping block 4. When the pressure sensor 5 conflicts with the other end of the damping block 4, the pressure generated can determine that the device has pressure loss and needs to be replaced or maintained.

[0044] Finally, during daily use, the heat conductive sheet 14 cooperates with the resistance balloon 13 to resist the outer wall of the connected pipe, and then the temperature of the connected pipe is monitored through the heat transfer of the heat conductive sheet 14 and the temperature sensor probe 15. When a temperature abnormality occurs, the device can have a certain early warning function. At the same time, through the set inspection port 17, when it is necessary to maintain or overhaul the components inside the main cavity 3 of the flame arrester, the sealing cover plate 18 can be removed, and then the components inside the main cavity 3 of the flame arrester can be maintained or overhauled through the inspection port 17. A flame arrester with a pressure loss detection function is now in use.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
