Description

Technical Field

[0001] This utility model relates to the field of gas detection technology for gas pipelines, specifically a gas detection connection valve for gas pipelines. Background Technology

[0002] Gas pipelines are key infrastructure for transporting energy such as natural gas and liquefied petroleum gas. Their safety and reliability directly affect energy supply and public safety. Gas pipelines are usually made of corrosion-resistant, high-strength steel pipes or PE pipes, which have the characteristics of strong pressure resistance and long service life. Valves include ball valves, gate valves, safety valves and other types, which have advantages such as fast opening and closing, high pressure resistance and leakage prevention.

[0003] Most of the current connecting valves rely on electromagnetic force for control. When there is a strong magnetic field in the surrounding area, it may interfere with the control of the solenoid valve, causing abnormal operation and making it easy for gas to be inaccurately detected. Utility Model Content

[0004] This utility model provides a gas detection connection valve for gas pipelines, which can use a pressure detector to detect the gas in the gas pipeline. By detecting the gas pressure, the detection data is transmitted to the detection instrument panel via wire. When the data is abnormal, the detection instrument panel controls an electric cylinder via wire, which pushes a baffle to cover the gas delivery channel.

[0005] To achieve the above objectives, a gas detection connection valve for a gas pipeline is provided, comprising a valve body, an internal gas delivery mechanism on the inner surface of the valve body, a connecting pipe fixedly connected to the upper surface of the valve body, a connecting disc fixedly connected to the upper surface of the connecting pipe, two connecting discs being provided, a bolt threadedly connected to the upper surface of the upper connecting disc, a nut threadedly connected to the outer surface of the bolt, and multiple bolts and nuts being provided, a cylinder wall fixedly connected to the upper surface of the upper connecting disc, a cylinder top fixedly connected to the upper surface of the cylinder wall, a connecting block fixedly connected to the upper surface of the cylinder top, an electric cylinder fixedly connected to the front surface of the connecting block, a baffle plate fixedly connected to the output end of the electric cylinder, and a gas pipe body fixedly connected to the side surface of the valve body.

[0006] According to the aforementioned gas pipeline gas detection connection valve, the gas pipeline body is provided with two parts, and the outer surface of the electric cylinder is electrically connected with wires. By providing wires, data can be transmitted through the wires.

[0007] According to the aforementioned gas pipeline gas detection connection valve, two wires are provided, one end of which is electrically connected to a detection instrument panel body. The detection instrument panel body, model YLBJQ-001, is used to output and display the gas pressure status.

[0008] According to the gas pipeline gas detection connection valve, one end of the detection instrument panel body on the left is electrically connected to a pressure detector body, and the lower end of the switch is fixedly connected to the upper surface of the gas pipeline body on the left. By setting the pressure detector body, the pressure detector body can use the gas pressure method to detect the gas pressure inside the gas pipeline body on the left. When the gas pressure is abnormal, the data is transmitted to the detection instrument panel body through the wire.

[0009] According to the gas detection connection valve for a gas pipeline, the gas transmission mechanism includes an outer plate, an inner plate, and a connecting plate. The outer plate is fixedly connected to the inner surface of the valve body. The outer plate is hook-shaped. By setting the outer plate to a hook shape, a space can be provided for the transmission of gas, making it easier for the baffle to block the gas transmission groove.

[0010] According to the gas detection connection valve for a gas pipeline, the inner plate is fixedly connected to the inner surface of the valve body. The inner plate is hook-shaped. By setting the inner plate, it is easy for the baffle to block the gas delivery groove, thereby achieving the blocking effect.

[0011] According to the aforementioned gas pipeline gas detection connection valve, the connection plate is fixedly connected to the inner surface of the connection valve body, and the connection plate is fixedly connected to the outer plate. By setting the connection plate, the connection plate can block part of the gas delivery channel to prevent some gas from leaking when the gas is blocked.

[0012] According to the aforementioned gas pipeline gas detection connection valve, the connecting plate is fixedly connected to the inner plate, and a gas delivery groove is provided between the connecting plate and the inner plate. By providing the gas delivery groove, the gas in the gas pipe body can be delivered to the interior of another gas pipe body.

[0013] The beneficial effects of this utility model are as follows: By setting up structures such as a baffle plate, a gas delivery mechanism, and a pressure detector body, after the switch, pressure detector body, and detection instrument panel body are turned on, the gas in the gas pipe body will be normally transmitted through the gas delivery channel. When the gas pressure in the gas pipe body is too high or too low, the pressure detector body will transmit the data to the detection instrument panel body, thus achieving the effect of detecting the gas pressure. The detection instrument panel body will use wires to control an electric cylinder. The electric cylinder will push the baffle plate down through the output end until the baffle plate blocks the gas delivery channel, thus blocking the gas and preventing the gas pressure from being too high and causing damage to other equipment.

[0023] Reference Figures 1 to 5This utility model discloses a gas detection connection valve for a gas pipeline, comprising a connection valve body 1, a gas delivery mechanism 12 disposed on the inner surface of the connection valve body 1, a connection pipe 2 fixedly connected to the upper surface of the connection valve body 1, a connection disc 3 fixedly connected to the upper surface of the connection pipe 2, two connection discs 3 are provided, a bolt 4 is threadedly connected to the upper surface of the upper connection disc 3, a nut 5 is threadedly connected to the outer surface of the bolt 4, multiple bolts 4 and nuts 5 are provided, a cylinder wall 6 is fixedly connected to the upper surface of the upper connection disc 3, a cylinder top 7 is fixedly connected to the upper surface of the cylinder wall 6, a connection block 8 is fixedly connected to the upper surface of the cylinder top 7, an electric cylinder 9 is fixedly connected to the front surface of the connection block 8, a baffle plate 11 is fixedly connected to the output end of the electric cylinder 9, and a gas pipe body 13 is fixedly connected to the side surface of the connection valve body 1.

[0024] There are two gas pipe bodies 13. The outer surface of the electric cylinder 9 is electrically connected to wires 14. There are two wires 14. One end of the wire 14 is electrically connected to the detection instrument panel body 15. One end of the left detection instrument panel body 15 is electrically connected to the pressure detector body 16. The lower end of the switch 17 is fixedly connected to the upper surface of the left gas pipe body 13. Data can be transmitted through the wires 14. The detection instrument panel body 15, model YLBJQ-001, is used to output and display the gas pressure status. The pressure detector body 16 can detect the gas pressure inside the left gas pipe body 13 using the gas pressure method. When the gas pressure is abnormal, the data is transmitted to the detection instrument panel body 15 through the wires 14.

[0025] The inner plate 1202 is fixedly connected to the inner surface of the connecting valve body 1. The inner plate 1202 is hook-shaped. The connecting plate 1203 is fixedly connected to the inner surface of the connecting valve body 1. The connecting plate 1203 is fixedly connected to the outer plate 1201 and the inner plate 1202. A gas delivery groove is provided between the connecting plate 1203 and the inner plate 1202. The inner plate 1202 facilitates the blocking plate 11 to block the gas delivery groove, thus playing a blocking role. The connecting plate 1203 can block part of the gas delivery groove to prevent some gas from leaking when the gas is blocked. Through the gas delivery groove, the gas in the gas pipe body 13 can be delivered to another gas pipe body 13.

[0026] The gas delivery mechanism 12 includes an outer plate 1201, an inner plate 1202 and a connecting plate 1203. The outer plate 1201 is fixedly connected to the inner surface of the connecting valve body 1. The outer plate 1201 is hook-shaped. The hook shape of the outer plate 1201 can provide a space for the transmission of gas, making it easier for the baffle plate 11 to block the gas delivery groove.

[0027] Working principle: When the pressure detector body 16, switch 17, and detection instrument panel body 15 are activated, the gas in the gas pipe body 13 will be transmitted through the connecting valve body 1. At this time, the pressure detector body 16 will detect the gas pressure in the gas pipe body 13 and transmit the data to the detection instrument panel body 15 via the wire 14. When the pressure detector body 16 detects that the gas pressure in the gas pipe body 13 is too high or too low, the detection instrument panel body 15 will operate the electric cylinder 9 via the wire 14. The electric cylinder 9 pushes the baffle plate 11 through the push rod 10 to cover the gas delivery groove. When the gas delivery groove is covered, the gas cannot be transmitted, thus preventing the gas pressure from exceeding the pressure resistance limit of the gas pipe body 13 and causing the gas pipe body 13 to rupture. When the connecting valve body 1 becomes blocked after long-term use, after turning off the switch 17, pressure detector body 16, and detection instrument panel body 15, the cylinder wall 6 and connecting pipe 2 can be disassembled after loosening the bolt 4, which facilitates maintenance of the internal structure of the connecting valve body 1.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
