Description

Technical Field

[0001] The present invention belongs to the technical field of gas self-closing valves, and more specifically, particularly relates to a gas self-closing valve with a leakage detection function. Background Art

[0002] The gas self-closing valve is a safety device used in the gas system, designed to prevent gas leakage and ensure safety. Its main function is to automatically shut off the gas supply when an abnormality occurs in the gas pipeline (such as pipeline breakage, fire, etc.) to avoid dangerous situations.

[0003] Some current gas self-closing valves are not convenient for detecting leakage in the gas channel. When a gas leak occurs, the user still needs to manually close the supply side of the gas pipeline, which increases the risk of use. In addition, some current gas self-closing valves are not convenient for locating the position of the valve body leak. After solving the leakage problem, the user needs to re-locate the leakage position, which is inefficient.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a gas self-closing valve with a leakage detection function is provided, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a gas self-closing valve with a leakage detection function, which is achieved by the following specific technical means:

[0006] A gas self-closing valve with a leakage detection function comprises a self-closing valve body, a spherical valve disc is installed on one side inside the self-closing valve body, a through groove is penetrated at the middle position of the spherical valve disc, an electric control component is installed on one side of the top end of the self-closing valve body at a position above the spherical valve disc, an auxiliary sealing component is installed at the end of the self-closing valve body away from the spherical valve disc, a positioning component is installed on one side of the self-closing valve body, and a master control detector is threadedly connected to the bottom end of the self-closing valve body.

[0007] Furthermore, the electronic control component includes a first chassis, which is installed on one side of the top of the self-closing valve body through a bracket at a position directly above the spherical valve disc, a first worm gear is rotatably installed inside the first chassis, and the first worm gear is connected to the spherical valve disc through a connecting rod, a first worm is rotatably installed on one side inside the first chassis, and the first worm is meshingly connected to the first worm wheel.

[0008] Furthermore, a buzzer alarm is installed on the top of the first chassis.

[0009] Furthermore, a first motor is installed on one side of the first chassis, and an output end of the first motor is connected to the first worm gear through a coupling.

[0010] Furthermore, the auxiliary sealing assembly includes a first mounting seat, which is mounted on the bottom end of the self-closing valve body away from the spherical valve disc, and a first slide groove is provided at the top of the first mounting seat, and a pair of first sliders are symmetrically installed at both ends of the first slide groove, and a pair of first arc-shaped clamping plates are symmetrically installed at the top of the pair of first sliders through a bracket, and a pair of first arc-shaped clamping plates are installed with sealing gaskets on opposite sides.

[0011] Furthermore, a first bidirectional screw is rotatably installed in the first sliding groove, and the first bidirectional screw passes through the left and right sides of a pair of first sliding blocks and is threadedly connected to the pair of first sliding blocks.

[0012] Furthermore, a first knob is installed on one side of the first mounting seat, and the first knob is transmission-connected to the first bidirectional screw.

[0013] Furthermore, the positioning assembly includes a second mounting seat, which is installed on one side of the self-closing valve body. A second slide groove is provided at the top of the second mounting seat, and a second slider is slidably installed in the second slide groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The gas self-closing valve with a leakage detection function in the present invention is convenient for detecting the gas composition in the environment at any time through the gas sensor during the use of the gas self-closing valve, and uploading the detected gas data to the master control detector. When it is detected that the content of some gases exceeds the standard, the first motor and the second motor are opened at the same time, so that the spherical valve disc cuts off the gas on the supply side of the gas pipeline, and detects the gas composition at different positions of the gas self-closing valve through the movement of the second slider and the gas sensor. The position with the highest gas content is located by the master controller, thereby realizing the positioning of the gas leakage position, thereby improving the detection effect and detection efficiency of the gas self-closing valve, further reducing the possibility of personnel and property loss, and improving the convenience of later maintenance.

The connection between the self-closing valve body and the output side pipeline is further sealed, thereby further reducing the possibility of gas leakage after long-term use, thereby improving the safety of the gas self-closing valve and reducing the probability of safety accidents.

[0030] Example:

[0031] As attached Figure 1 To Attachment Figure 6 As shown:

[0032] The present invention provides a gas self-closing valve with a leakage detection function, comprising a self-closing valve body 1, a spherical valve disc 2 is installed on one side inside the self-closing valve body 1, a through groove 3 is penetrated at the middle position of the spherical valve disc 2, an electric control component is installed on one side of the top of the self-closing valve body 1 at a position above the spherical valve disc 2, an auxiliary sealing component is installed at the end of the self-closing valve body 1 away from the spherical valve disc 2, a positioning component is installed on one side of the self-closing valve body 1, and a master control detector 4 is threadedly connected to the bottom end of the self-closing valve body 1, and the master control detector 4 is electrically connected to a first motor 9, a second motor 23, a buzzer alarm 8 and a gas sensor 20, respectively, so as to facilitate the control of the overall circuit of the gas self-closing valve and record and analyze the gas components collected by the gas sensor 20.

[0033] Among them, the electronic control component includes a first chassis 5, which is installed on one side of the top of the self-closing valve body 1 through a bracket at a position directly above the spherical valve flap 2. A first worm gear 6 is rotatably installed inside the first chassis 5, and the first worm gear 6 is connected to the spherical valve flap 2 through a connecting rod. A first worm 7 is rotatably installed on one side inside the first chassis 5, and the first worm 7 is meshingly connected with the first worm gear 6. Through the rotation of the first worm 7, since the first worm 7 is meshingly connected with the first worm gear 6, the first worm gear 6 rotates together and drives the spherical valve flap 2 to rotate. When a gas leak is detected, the spherical valve flap 2 rotates 90 degrees and closes one end of the self-closing valve body 1 close to the supply side pipeline, thereby avoiding the need for the user to manually close the gas supply side valve after a gas leak occurs, thereby reducing the risk.

[0034] A buzzer alarm 8 is installed at the top of the first chassis 5. The buzzer alarm 8 can continuously sound an alarm when the gas self-closing valve detects a gas leak, reminding the user that there is a gas leak and needs to be checked immediately.

[0035] Among them, a first motor 9 is installed on one side of the first chassis 5, and the output end of the first motor 9 is connected to the first worm 7 through a coupling. The first motor 9 drives the first worm 7 to rotate. Since the first worm 7 is meshingly connected with the first worm gear 6, the first worm gear 6 rotates together and drives the spherical valve flap 2 to rotate, thereby controlling the pipeline switch on the supply side of the gas self-closing valve through the rotation of the spherical valve flap 2.

[0036] Among them, the auxiliary sealing component includes a first mounting seat 10, which is mounted on the bottom end of the self-closing valve body 1 away from the spherical valve disc 2. A first slide groove 11 is provided at the top of the first mounting seat 10, and a pair of first sliders 12 are symmetrically installed at both ends of the first slide groove 11. A pair of first arc-shaped clamping plates 13 are symmetrically installed at the top of the pair of first sliders 12 through a bracket. A pair of first arc-shaped clamping plates 13 are installed with sealing gaskets 14 on opposite sides. Through the relative movement of the pair of first arc-shaped clamping plates 13, it is convenient to improve the sealing of the connection after the self-closing valve body 1 is connected to the pipeline on the output side, and the sealing effect is further improved by the setting of the sealing gasket 14, thereby reducing the gas leakage at the connection between the self-closing valve body 1 and the output side pipeline after the gas self-closing valve is used for a long time.

[0037] Among them, a first bidirectional screw 15 is rotatably installed in the first slide groove 11, and the first bidirectional screw 15 passes through the left and right sides of a pair of first sliders 12 and is threadedly connected to the pair of first sliders 12. Through the rotation of the first bidirectional screw 15, under the limiting action of the first slide groove 11, the pair of first sliders 12 move toward or away from each other at the same time, so that the pair of first arc-shaped clamping plates 13 can clamp or loosen the connection between the self-closing valve body 1 and the output side pipeline, thereby improving the sealing of the connection.

[0038] Among them, a first knob 16 is installed on one side of the first mounting seat 10, and the first knob 16 is transmission-connected with the first bidirectional screw 15. The first knob 16 drives the first bidirectional screw 15 to rotate. Under the limiting action of the first slide groove 11, a pair of first sliding blocks 12 move toward or away from each other at the same time, thereby driving a pair of first arc-shaped clamping plates 13 to clamp or loosen the connection between the self-closing valve body 1 and the output side pipeline.

[0039] Among them, the positioning component includes a second mounting seat 17, which is installed on one side of the self-closing valve body 1. A second slide groove 18 is provided at the top of the second mounting seat 17. A second slider 19 is slidably installed in the second slide groove 18. A gas sensor 20 is installed at the top of the second slider 19, and the gas sensor 20 is electrically connected to the master control detector 4. The model of the gas sensor 20 can be Mi CS-5524, etc. The gas conditions near the gas self-closing valve can be collected at any time, and the collected data can be uploaded to the master control detector 4 for analysis. When it is detected that the gas content exceeds the standard, the first motor 9 and the second motor 23 are opened at the same time. After the first motor 9 closes the pipeline on the supply side, the second motor 23 drives the second screw 21 to rotate. Under the limiting action of the second slide groove 18, the second slider 19 moves and drives the gas sensor 20 to move. The gas sensor 20 continuously collects gas components at different positions. The master control detector 4 locates the position with the highest leakage gas content and controls the second slider 19 to stay at this position through the second motor 23.

[0040] Among them, a second screw 21 is rotatably installed in the second slide groove 18, and the second screw 21 passes through the front and rear sides of the second slider 19 and is threadedly connected to the second slider 19. Through the rotation of the second screw 21, under the limiting action of the second slide groove 18, the second slider 19 moves and drives the gas sensor 20 to move, so that the gas sensor 20 can collect gas components at different positions.

[0041] Among them, a second chassis 22 is installed on one side of the second mounting base 17, and a second motor 23 is installed in the second chassis 22, and the output end of the second motor 23 is transmission-connected to the second screw 21 through a coupling, and the second motor 23 drives the second screw 21 to rotate. Under the limiting action of the second slide groove 18, the second slider 19 moves and drives the gas sensor 20 to move.

[0042] The working principle of this embodiment: when installing the gas self-closing valve with a leakage detection function, the user first connects the self-closing valve body 1 to the supply side and the output side of the gas pipeline respectively. After the installation is completed, the first knob 16 is rotated. The first knob 16 drives the first bidirectional screw 15 to rotate. Under the limiting action of the first slide groove 11, a pair of first sliders 12 move toward each other at the same time, so that a pair of first arc-shaped clamping plates 13 can clamp the connection between the self-closing valve body 1 and the output side pipeline, so as to improve the sealing of the connection after the self-closing valve body 1 is connected to the output side pipeline, and the sealing effect is further improved by the setting of the sealing gasket 14, so as to reduce the gas leakage at the connection between the self-closing valve body 1 and the output side pipeline after the gas self-closing valve is used for a long time. During the use of the gas self-closing valve with a leakage detection function, the gas sensor 20 can continuously collect the gas content of the gas near the gas self-closing valve, and upload the collected gas data to the master control detector 4. The master control detector 4 The data is recorded and analyzed. When a gas leak is detected, the first motor 9 and the second motor 23 are turned on at the same time. The first motor 9 drives the first worm 7 to rotate. Through the rotation of the first worm 7, since the first worm 7 is meshed and connected with the first worm gear 6, the first worm gear 6 rotates together and drives the spherical valve flap 2 to rotate. The spherical valve flap 2 rotates 90 degrees and closes the end of the self-closing valve body 1 close to the supply side pipeline, thereby avoiding the need for the user to manually close the gas supply side valve after the gas leak occurs, reducing the risk. The second motor 23 drives the second screw 21 to rotate. Under the limiting action of the second slide groove 18, the second slider 19 moves and drives the gas sensor 20 to move, so that the gas sensor 20 can collect the gas components at different positions. The master control detector 4 locates the position with the highest leakage gas content, and controls the second slider 19 to stay at this position through the second motor 23, so that after solving the leakage problem, the user can quickly locate and process the leakage position, thereby improving the processing efficiency.
