Description

Technical Field

[0001] The present invention relates to the technical field of gas valves, and particularly to an automatic flow-detecting gas pipeline self-closing valve. Background Art

[0002] As a clean energy with the characteristics of "low consumption, high return, low pollution, and high efficiency", gas has been widely used in people's daily production and life. The medium and high pressure of the gas pipeline entering the household is adjusted to low pressure by a pressure regulator. If the pressure regulator fails, too high or too low pressure directly entering the household will also cause safety accidents. Using rubber hoses or corrugated hoses to connect with the stove, the disconnection or rupture of the connecting pipe will also cause safety accidents. In view of the above safety hazards in the process of gas use, it is usually necessary to install a safety valve with the function of automatically cutting off the gas pipeline, that is, a self-closing valve. The self-closing valve is installed on the gas system pipeline. When the gas supply pressure in the pipeline is underpressure, overpressure, or the flow is abnormal, it can automatically close without electricity or other external power to ensure the safe use of gas.

[0003] However, after long-term use of the self-closing valve, the bolts fixing the self-closing valve will become loose, resulting in gas leakage. Since gas itself has serious hazards, it is necessary to detect the existing self-closing valve. Although the existing self-closing valve detection device basically meets the use requirements, there are still some problems. For example, there is no purification device outside the self-closing valve. When gas leaks, it cannot absorb the gas in the first time, thus reducing the harm to users. Therefore, the practicability of the device is reduced. Therefore, an automatic flow-detecting gas pipeline self-closing valve is proposed to solve the existing problems. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides an automatic flow-detecting gas pipeline self-closing valve, which has the advantages of good protection effect, etc., and solves the problem that there is no purification device outside the self-closing valve and the gas cannot be absorbed in the first time.

A detection pipe 8 is fixedly installed on the output end of the automatic detection device 7. An ultrasonic fluid induction alarm mechanism 13 is arranged outside the gas transmission pipe 1 and is communicated with the connecting pipe 4 through the detection pipe 8. At this time, the gas flows into the automatic detection device 7, and the automatic detection device 7 detects the gas, so as to achieve the effect of automatically detecting the gas. The protection component includes a gas purification device 17 arranged outside the gas transmission pipe 1. An output pipe 18 is arranged outside the gas transmission pipe 1. An inhalation nozzle 19 is fixedly installed outside the output pipe 18. The output end of the gas purification device 17 is fixedly installed with a connecting pipe. One end of the connecting pipe far away from the gas purification device 17 is fixedly connected with the output pipe 18. Through the ultrasonic fluid induction alarm mechanism 13, effective gas leakage monitoring of the gas transmission pipe 1 can be carried out. When there is gas leakage, the ultrasonic fluid induction alarm mechanism 13 will be triggered, so that the ultrasonic fluid induction alarm mechanism 13 will issue an alarm. Furthermore, the control switch 16 will start the gas purification device 17. The gas is absorbed through the inhalation nozzle 19 and transported into the interior of the output pipe 18, and then transported into the interior of the gas purification device 17 through the connecting pipe, so as to process the leaked gas.

[0028] Among them, a through - pipe is fixedly installed at the bottom of the gas transmission pipe 1. A through - opening adapted to the through - pipe is opened inside the gas transmission pipe 1. A positioning plate is fixedly installed at the bottom of the through - pipe. A positioning hole is opened inside the positioning plate. An air - delivery port adapted to the inhalation nozzle 19 is opened inside the output pipe 18.

[0029] It should be noted that the automatic detection device 7, the ultrasonic fluid induction alarm mechanism 13, the control switch 16 and the gas purification device 17 are all conventional devices well - known to the public in the prior art. Therefore, the specific structural composition and working principle are not described in detail in this text.

[0030] In this embodiment, a connecting sleeve 5 is fixedly installed outside the connecting pipe 4. One side of the mounting frame 6 far away from the automatic detection device 7 is fixed to the connecting sleeve 5. The connecting sleeve 5 and the connecting pipe 4 are connected by a first fastening bolt. And a sealing sleeve is movably installed at the connection of the connecting sleeve 5 and the connecting pipe 4. The sealing sleeve can strengthen the sealing performance between the connecting sleeve 5 and the connecting pipe 4, so that gas leakage will not easily occur, achieving a sealing effect.

[0031] Among them, the mounting bracket 6 includes fixed backing plates arranged on the opposite sides of the automatic detection device 7 and the connecting sleeve 5. The number of fixed backing plates is two. Support rods are fixedly installed on the opposite sides of the two fixed backing plates. The opposite sides of the automatic detection device 7 and the connecting sleeve 5 are respectively fixed to the opposite sides of the two fixed backing plates through fastening bolts, and the number of fastening bolts is multiple.

[0032] It should be noted that a sealing gasket is fixedly installed on the outside of the detection tube 8. A locking bolt is movably installed inside the sealing gasket. The sealing gasket and the right fixed backing plate are fixed through the locking bolt, and an air vent adapted to the detection tube 8 is provided inside the right fixed backing plate.

[0033] In this embodiment, the detection tube 8 is communicated with the connecting sleeve 5. A connecting sleeve 9 is fixedly installed on the top of the connecting sleeve 5. A fixed seat 10 and a flowmeter 11 are arranged on the outside of the connecting sleeve 9. The flowmeter 11 is fixed to the fixed seat 10. A fixed block is fixedly connected to the side of the fixed seat 10 away from the flowmeter 11. An installation bolt is movably installed inside the fixed block. The fixed block and the connecting sleeve 9 are fixed through the installation bolt.

[0034] Moreover, an installation pipe is arranged on the outside of the flowmeter 11. The installation pipe is movably connected to the flowmeter 11 and the automatic detection device 7 respectively.

[0035] In this embodiment, a first electric push rod 12 is fixedly installed on the outside of the connecting pipe 4. The ultrasonic fluid induction alarm mechanism 13 is fixedly connected to the output end of the first electric push rod 12. By starting the first electric push rod 12, its output end drives the ultrasonic fluid induction alarm mechanism 13 to displace, so that the alarm range of the ultrasonic fluid induction alarm mechanism 13 becomes wider.

[0036] In this embodiment, an installation column 14 is fixedly installed on the outside of the connecting pipe 4. A control switch 16 is fixedly installed at one end of the installation column 14 close to the first valve 2. An adjusting component is arranged on the outside of the output pipe 18. The adjusting component includes a fixed rod 20 fixedly installed on the top of the output pipe 18. A limiting block 21 is fixedly installed on the top of the fixed rod 20. A second electric push rod 23 is fixedly installed on the outside of the installation column 14. The fixed rod 20 is fixedly connected to the output end of the second electric push rod 23. By starting the second electric push rod 23, its output end pushes the fixed rod 20 to displace, thereby driving the output pipe 18 and the suction nozzle 19 to displace, and then being able to quickly absorb and process the leaked gas.

[0037] It should be noted that the number of connecting pipes 4 is two. The detection device is close to the left connecting pipe 4, and the connecting sleeve 5 is connected to the left connecting pipe 4. The first electric push rod is fixedly installed on the top of the left connecting pipe 4. The connecting pipe is a flexible pipe, which is convenient for adjustment.

[0038] Among them, the number of mounting posts 14 is two. The two mounting posts 14 are horizontally distributed outside the two connecting pipes 4. A positioning seat is fixedly installed outside the mounting posts 14. A positioning block is fixedly installed on the side of the positioning seat close to the gas purification device 17. A positioning bolt is movably installed inside the positioning block. The positioning block and the gas purification device 17 are fixed by the positioning bolt. And the number of positioning bolts is multiple, and the number of positioning seats and positioning blocks is four.

[0039] In this embodiment, a mounting plate 15 is fixedly installed at the top of the mounting post 14. A limiting groove adapted to the limiting block 21 is opened inside the mounting plate 15. The limiting block 21 is slidably connected to the limiting groove. A mounting rod is fixedly installed on the side of the limiting block 21 away from the fixed rod 20. A pulley 22 is movably installed outside the mounting rod. The pulley 22 is slidably connected to the inner top wall of the limiting groove. When the fixed rod 20 displaces, the limiting block 21 fixedly connected to it slides inside the limiting groove accordingly, and at the same time drives the pulley 22 to roll. At this time, the pulley 22 rolls on the inner top wall of the limiting groove, so as to facilitate the second electric push rod 23 to drive the output pipe 18 to displace.

[0040] Among them, through the limitation of the limiting block 21 by the limiting groove, the fixed rod 20 can always maintain stable displacement when it displaces, thereby improving stability.

[0041] It should be noted that the number of the fixed rod 20, the limiting block 21, the mounting rod and the pulley 22 is two.

[0042] In this embodiment, both the first valve 2 and the second valve 3 are movably installed outside the gas pipeline 1. Through the first valve 2 and the second valve 3, it is convenient to use the gas inside the gas pipeline 1.

[0043] It should be noted that the first valve 2 and the second valve 3 are conventional devices well known to the public in the prior art. Therefore, the specific structural composition and working principle thereof will not be described in detail in this text.

[0044] The beneficial effects of the above embodiments are:

[0045] The automatic detection flow gas pipeline self-closing valve can effectively monitor the gas leakage of the gas transmission pipe 1 through the ultrasonic fluid induction alarm mechanism 13. When there is gas leakage, it will trigger the ultrasonic fluid induction alarm mechanism 13, so that the ultrasonic fluid induction alarm mechanism 13 emits an alarm. Furthermore, the control switch 16 will start the gas purification device 17, absorb the gas through the suction nozzle 19 and transport it to the inside of the output pipe 18, and then transport it to the inside of the gas purification device 17 through the connecting pipe, so as to process the leaked gas. At the same time, the second electric push rod 23 is started, and its output end pushes the fixed rod 20 to displace, so as to drive the output pipe 18 and the suction nozzle 19 to displace, and thus can quickly absorb and process the leaked gas.

[0046] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed electrical connection technology will not be elaborated in the text.
