Embodiment 1

[0046] Such as Figure 1-Figure 11 As shown, the stainless steel bellows hybrid intelligent leak detection method based on wireless sensor linkage in this embodiment adopts the stainless steel bellows pipeline system for indoor gas in this embodiment, including the following process, and a leak detection box is set in the pipeline system 3. The bellows 10 is provided with a sensing fiber and a vibration sensor. The pressure sensor and flow sensor in the leak detection box 3 detect the gas pressure and flow signal in the pipeline in real time, and transmit the vibration signal detected by the vibration sensor to the leak detection The CPU processor 202 in the box 3, the CPU processor 202 transmits the signal characteristics to the data platform server 4 through the communication module;

[0047] b. The data platform server 4 comprehensively judges the pipeline status according to the extracted pressure, vibration, and flow characteristics. When the judgment feature is gas leaka...

Embodiment 2

[0054] The stainless steel bellows hybrid intelligent leak detection method based on wireless sensor linkage in this embodiment is basically the same as that in Embodiment 1, further, as Figure 4 with Figure 5 As shown, in this embodiment, the valve body 100 is provided with a main flow cavity 101 for gas circulation, but the main flow cavity 101 located on the front and rear sides of the sealing interface is not directly connected, but the main flow cavity 101 is opened in the front and rear respectively, and the sealing An inner sealing cylinder 103 is arranged in the interface, and the inner sealing cylinder 103 and the front end of the valve body 100 (such as Figure 5 The gap between the main flow chambers 101 on the left side of the orientation) is the outer flow chamber 102, and the inner seal cylinder 103 is provided with an inner flow chamber 104, which is connected to the rear end of the valve body 100 (such as Figure 5 The main flow cavity 101 on the right side ...

Embodiment 3

[0058] The stainless steel bellows hybrid intelligent leak detection method based on wireless sensor linkage in this embodiment is basically the same as the above embodiment, further, as Figure 9 As shown, the double-cavity sealing ring 400 in this embodiment includes an inner ring body 410 for pressing and sealing the inner circulation chamber 104, and an outer ring body with an inverted U-shaped cross section is arranged around the outer side of the inner ring body 410 upwards and circumferentially. 420, the outer edge of the outer ring body 420 is also provided with an outward extension section, the extension section is embedded in the inner side of the end cover cover 106, and the bottom of the extension section is provided with a circle of lower convex section 421, and the lower convex section 421 is embedded in the valve body below 100; the extension section is also provided with an inner convex section 422 at the contact position of the U-shaped opening, which is an arc...

Abstract

The invention discloses a stainless steel corrugated pipe hybrid intelligent leakage detection method based on wireless sensor linkage, and belongs to the field of gas leakage detection. A pressure sensor and a flow sensor in a leakage detection box detect the gas pressure and flow signals in the pipeline in real time, the gas pressure, the flow signals and vibration signals detected by a vibration sensor are jointly transmitted to a CPU processor in the leakage detection box, and the CPU processor transmits signal characteristics to a data platform server through a communication module; and the data platform server comprehensively judges the pipeline state according to the extracted characteristics, when the characteristics are judged as gas leakage, an automatic pipeline valve is controlled through the CPU processor, and an alarm module is controlled to give an alarm. According to the method, the defect of insufficient safety of an indoor gas pipeline in the prior art is overcome, and the efficiency and the precision of gas leakage detection of the stainless steel corrugated pipeline system for the indoor gas are improved.

Description

technical field [0001] The invention relates to the technical field of gas pipelines, in particular to a hybrid intelligent leak detection method for stainless steel bellows based on wireless sensor linkage. Background technique [0002] Leakage of gas pipelines is absolute, and no leakage is relative. According to incomplete statistics, there were 950 explosions caused by gas leakage in 2017, including about 700 indoor gas explosions and 200 outdoor gas leakage and explosions, resulting in a total of 104 deaths and 1,145 injuries. In 2017, among the explosion accidents caused by gas leakage, indoor accidents accounted for about 73%. The casualties and huge economic losses caused cannot be ignored. The indoor gas pipeline system is the top priority of gas safety. Stainless steel corrugated pipe is one of the new materials for indoor gas pipelines. It can be used as a gas stainless steel corrugated hose for indoor connection and a gas stainless steel corrugated hose for indo...
