Description

Technical Field

[0001] This application relates to the field of gas pipeline equipment technology, and in particular, to a terminal gas pipeline control device. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.

[0003] With the acceleration of urbanization in my country, natural gas, as a clean and efficient energy source, has been widely used. However, during the gas supply process, fluctuations in gas pressure can easily lead to unstable gas supply to end users, affecting their normal use. Increasing the overall gas transmission flow rate puts pressure on upstream gas branch networks, posing a risk to all users across the network.

[0004] For example, Chinese Patent Publication No. CN219102717U discloses a gas pipeline end pressure detection device, which includes a U-shaped pressure gauge body and a support mechanism. The support mechanism includes an adjustment frame, a support plate, an adjustment component, and a reinforcing component. The adjustment component includes a lead screw, a sliding seat, and a push-pull rod. The end of the push-pull rod is hinged to the bottom surface of the support plate. A control rod fixed to one end of the lead screw is inserted through the top of the adjustment frame. With the setting of the adjustment component and the support plate, this utility model allows the support plate to be rotated to a 90-degree perpendicular state with the U-shaped pressure gauge body during use. Thus, the U-shaped pressure gauge body only needs to be placed on the ground near the pipeline to be tested, and the support plate can effectively contact the ground, providing a reliable auxiliary support effect for the U-shaped pressure gauge body and ensuring the vertical state of the U-shaped pressure gauge body during testing. In existing technology, a latex tube from a U-shaped manometer is fitted onto the pressure testing port of a gas pipeline. By opening the valve of the pressure testing port, the water column scale on the U-shaped manometer can be directly observed, thereby determining the pressure inside the pipeline.

[0005] However, due to the intricate nature of the gas pipelines at the end points, existing technologies, after determining the pressure within the pipelines, make it difficult for users to conveniently control individual end points, hindering flexible and easy use. Utility Model Content

[0006] In view of at least one of the above technical problems, this application provides a terminal gas pipeline control device, which can drive the control plate to rise and fall by adjusting the adjustment rod to adjust the cross-sectional area of ​​the internal channel of the control pipe, thereby controlling the pressure of the control pipe, which is convenient for users to flexibly and manually control.

[0007] According to one aspect of this application, a terminal gas pipeline control device is provided, comprising a delivery pipe, a regulating pipe, a support, a regulating rod, a regulating plate, and an elastic element:

[0008] The tail end of the delivery pipe is connected to the regulating pipe, which has an installation window. A bracket is set above the installation window. The regulating rod passes through the bracket vertically and is threaded to the bracket. The bottom end of the regulating rod is rotatably connected to the regulating plate. The regulating plate is sealed to the side wall of the installation window by elastic elements. The regulating rod is used to be twisted to raise and lower the regulating plate, thereby adjusting the cross-sectional area of ​​the internal channel of the regulating pipe to adjust the pressure of the gas inside the regulating pipe.

[0009] In some embodiments of this application, the tail end of the delivery pipe is connected to the first end of the regulating pipe by a thread.

[0010] In some embodiments of this application, a first pressure gauge and a second pressure gauge are respectively provided at the first end and the second end of the regulating tube.

[0012] In some embodiments of this application, a connecting bearing is provided on the adjusting plate, and the bottom end of the adjusting rod is connected to the connecting bearing.

[0013] In some embodiments of this application, a handle is provided at the top of the adjusting rod.

[0014] In some embodiments of this application, the adjusting rod is provided with scale lines.

[0015] In some embodiments of this application, the elastic element is an elastic plate, a soft sealing cloth, or a corrugated plate.

[0016] This application has the following beneficial effects:

[0017] This application presents a terminal gas pipeline control device that connects to the end of a delivery pipe via a regulating pipe to achieve terminal gas delivery. The gas pressure is regulated by changing the volume within the regulating pipe. The regulating pipe has an installation window, within which a regulating plate is vertically mounted. The regulating plate is sealed to the side wall of the installation window via an elastic element. A bracket is mounted on the installation window, and an regulating rod is threaded onto the bracket. The bottom end of the regulating rod is rotatably connected to the regulating plate. By turning the regulating rod, the regulating plate can be raised or lowered, thereby changing the cross-sectional area of ​​the internal channel of the regulating pipe to regulate the gas pressure within the pipe. This allows users to conveniently and flexibly control the terminal gas pressure.

[0026] A terminal gas pipeline control device includes a delivery pipe 1, a regulating pipe 2, a support 4, a regulating rod 5, a regulating plate 7, and an elastic element 8.

[0027] The tail end of the delivery pipe 1 is connected to the regulating pipe 2. The regulating pipe 2 has an installation window 3. The bracket 4 is set above the installation window 3. The regulating rod 5 passes through the bracket 4 in a vertical direction and is threadedly connected to the bracket. The bottom end of the regulating rod 5 is rotatably connected to the regulating plate 7. The regulating plate 7 is sealed to the side wall of the installation window 3 by means of elastic elements 8. The regulating rod 5 is used to be twisted to raise and lower, thereby driving the regulating plate 7 to raise and lower, and thus adjusting the cross-sectional area of ​​the internal channel of the regulating pipe 2 to achieve the pressure of the gas inside the regulating pipe 2.

[0028] This application utilizes a regulating pipe 2 connected to the tail end of the delivery pipe 1 to achieve end-point gas delivery, and regulates the gas pressure by changing the internal volume of the regulating pipe 2. The regulating pipe 2 has an installation window 3, within which an adjusting plate 7 is vertically and flexibly mounted. The adjusting plate 7 is sealed to the side wall of the installation window 3 via an elastic element 8. A bracket 4 is mounted on the installation window 3, and an adjusting rod 5 is mounted on the bracket 4. The adjusting rod 5 is threadedly connected to the bracket, and its bottom end is rotatably connected to the adjusting plate 7. By turning the adjusting rod 5, the adjusting plate 7 can be raised or lowered, thereby changing the cross-sectional area of ​​the internal channel of the regulating pipe 2 to regulate the gas pressure inside the pipe 2. This allows users to conveniently and flexibly control the end-point gas pressure.

[0029] Preferably, please refer to Figure 1 As shown, the tail end of the conveying pipe 1 is connected to the first end of the regulating pipe 2 by a thread.

[0030] It is understandable that by connecting the tail end of the conveying pipe 1 to the first end of the regulating pipe 2 with a thread, the regulating pipe 2 can be easily installed at the tail end of the conveying pipe 1, making it convenient for users to install and remove the regulating pipe 2.

[0031] Preferably, please refer to Figure 1 As shown, a first pressure gauge 11 and a second pressure gauge 12 are respectively installed at the first end and the second end of the regulating tube 2.

[0032] It is understandable that the first pressure gauge 11 can detect the gas pressure before it enters the regulating pipe 2, and the second pressure gauge 12 can detect the gas pressure after it is regulated by the regulating pipe 2, so that users can intuitively monitor and regulate the end gas pressure.

[0033] Preferably, please refer to Figure 1 As shown, the second end of the regulating pipe 2 is provided with an interface flange 13.

[0034] It is understandable that by setting an interface flange 13 at the second end of the regulating pipe 2, various pipes can be easily connected to the regulating pipe 2, effectively improving the applicability of the regulating pipe 2.

[0035] Preferably, please refer to Figure 1 and 2 As shown, a connecting bearing 9 is provided on the adjusting plate 7, and the bottom end of the adjusting rod 5 is connected to the connecting bearing 9.

[0036] It is understandable that by setting a connecting bearing 9 on the adjusting plate 7, the adjusting rod 5 and the adjusting plate 7 can be rotatably connected, and the subsequent disassembly of the adjusting rod 5 and the adjusting plate 7 can be facilitated.

[0037] Preferably, please refer to Figure 1 and 2As shown, a handle 10 is provided at the top of the adjusting rod 5.

[0038] Understandably, the handle 10 at the top of the adjusting rod 5 allows the user to easily turn the adjusting rod 5 manually, which helps improve the overall ease of use of the device and facilitates manual operation by the user.

[0039] Preferably, please refer to Figure 1 and 3 As shown, the adjusting rod 5 is equipped with scale lines 14.

[0040] It is understandable that by setting a scale line 14 on the adjusting rod 5, the scale line 14 can indicate that turning the adjusting rod 5 to different positions can adjust the pressure of the adjusting tube 2, making it convenient for users to make adjustments intuitively.

[0041] Preferably, the elastic element 8 is an elastic plate, a soft sealing cloth, or a corrugated plate.

[0042] It is understandable that the elastic element 8 has elasticity and extensibility. When the adjusting rod 5 drives the adjusting plate 7 to adjust its position, the elastic element 8 can cooperate with the adjusting plate 7 to maintain the sealing effect on the installation window 3, and does not affect the height adjustment of the adjusting plate 7, thereby smoothly changing the area of ​​the internal channel of the adjusting pipe 2 and realizing the overall pressure regulation of the adjusting pipe 2.
