Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure regulators, and particularly relates to a gas pressure regulator with remote cut-off. Background Art

[0002] A gas pressure regulator is a device used to regulate, stabilize, and control the gas supply pressure. In a gas pipeline system, since the pressure of natural gas or liquefied petroleum gas from the transmission pipeline may fluctuate or be too high, a gas pressure regulator is required to adjust it to an appropriate working pressure range to ensure the safe and stable operation of the equipment and system. The existing gas pressure regulators often adjust the pressure by squeezing a spring and a diaphragm by turning an adjusting part with a slotted head. However, due to the need for manual operation, remote operation cannot be achieved, which increases the inconvenience of operation. Therefore, we introduce a gas pressure regulator with remote cut-off. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a gas pressure regulator with remote cut-off, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A gas pressure regulator with remote cut-off includes a gas pressure regulator body. A high-pressure air inlet is fixedly connected to the front part of the outer surface of the gas pressure regulator body, and a low-pressure air outlet is fixedly connected to the rear part of the outer surface of the gas pressure regulator body. The upper end of the gas pressure regulator body is movably connected with an upper cover by screws. An extension part is fixedly connected to the upper end of the upper cover. An exhaust port is fixedly connected to the front part of the outer surface of the upper cover. A dust-proof device is movably connected in the exhaust port. An adjusting device is fixedly connected to the upper part of the inner wall of the extension part.

[0006] Preferably, the adjusting device includes a micro electric cylinder. A support frame is fixedly connected to the lower end of the micro electric cylinder. An adjusting part is fixedly connected to the telescopic end of the micro electric cylinder. A plurality of sealing rings are fixedly connected to the outer surface of the adjusting part. The telescopic end of the micro electric cylinder penetrates through the support frame.

[0007] By adopting the above technical solution: The lower end of the adjusting part is hollowed out, which is convenient for the spring to extend into the adjusting part to limit the spring and prevent the spring from shifting.

[0008] Preferably, the support frame is fixedly connected to the inner wall of the extension part. The adjusting part is located in the extension part. All three sealing rings are in contact with the inner wall of the extension part.

[0009] Preferably, the exhaust port has a structure that is wide in the front and narrow in the rear. The exhaust port is a hollow structure inside. Internal threads are provided on the front part of the inner wall of the exhaust port.

[0010] Preferably, the dust-proof device includes a frame. The outer surface of the frame is provided with external threads. A notch is formed inside the frame. A filter screen is fixedly connected to the rear part of the inner wall of the notch, and two protruding parts are fixedly connected to the front part of the inner wall of the notch.

[0011] Preferably, one end of each of the two protruding parts close to each other is of an arc surface structure.

[0012] Preferably, the frame is threadedly connected to the exhaust port through the external threads, and the filter screen is located inside the exhaust port.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, by providing an adjusting device, since the micro electric cylinder is installed on the inner wall of the extension part through a support frame, and the telescopic end of the micro electric cylinder is fixed to the adjusting part, starting the micro electric cylinder to work makes the micro electric cylinder push the adjusting part to move up and down, compressing and relaxing the spring inside the pressure regulator, thereby realizing the remote control of the regulator, facilitating the cutting off and opening of the gas. By fixing three sealing rings on the outer surface of the adjusting part, the sealing performance of the adjusting part sliding in the extension part is improved;

[0015] 2. In the utility model, by threadedly connecting the frame to the inner wall of the exhaust port through the external threads, the filter screen inside the frame can be flexibly installed and disassembled along with the frame. Thus, after the filter screen is contaminated with dust, it can be removed for cleaning, further avoiding the blockage of the exhaust port caused by difficult-to-clean dust accumulation. By fixedly connecting two protruding parts to the inner wall of the frame, the convenience of twisting and rotating the frame is improved under the action of the two protruding parts, facilitating the operation of personnel.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] A gas pressure regulator with remote cut-off, including a gas pressure regulator body 1, a high-pressure air inlet 8 is fixedly connected to the front part of the outer surface of the gas pressure regulator body 1, a low-pressure air outlet 2 is fixedly connected to the rear part of the outer surface of the gas pressure regulator body 1, the upper end of the gas pressure regulator body 1 is movably connected to an upper cover 3 by screws, an extension part 4 is fixedly connected to the upper end of the upper cover 3, an exhaust port 6 is fixedly connected to the front part of the outer surface of the upper cover 3, a dust-proof device 7 is movably connected inside the exhaust port 6, and an adjusting device 5 is fixedly connected to the upper part of the inner wall of the extension part 4.

[0026] In this embodiment, the adjusting device 5 includes a micro electric cylinder 51. A support frame 52 is fixedly connected to the lower end of the micro electric cylinder 51. An adjusting member 54 is fixedly connected to the telescopic end of the micro electric cylinder 51. A plurality of sealing rings 53 are fixedly connected to the outer surface of the adjusting member 54. The telescopic end of the micro electric cylinder 51 penetrates through the support frame 52. The support frame 52 is fixedly connected to the inner wall of the extension part 4. The adjusting member 54 is located inside the extension part 4. All three sealing rings 53 are in contact with the inner wall of the extension part 4. The exhaust port 6 has a structure that is wider at the front and narrower at the rear. The exhaust port 6 is a hollow structure inside. An internal thread 61 is provided on the front part of the inner wall of the exhaust port 6.

[0027] Through the above solution: The micro electric cylinder 51 pushes the adjusting member 54 to move up and down, driving the spring inside the gas pressure regulator body 1 to compress or relax, thereby achieving cutting off and pressure adjustment. By providing three sealing rings 53 on the outer surface of the adjusting member 54, the sealing performance of the adjusting member 54 is improved, avoiding gas leakage.

[0028] In this embodiment, the dust-proof device 7 includes a frame 71. External threads 72 are provided on the outer surface of the frame 71. A notch 74 is formed inside the frame 71. A filter screen 73 is fixedly connected to the rear part of the inner wall of the notch 74. Two protruding parts 75 are fixedly connected to the front part of the inner wall of the notch 74. The ends of the two protruding parts 75 close to each other are both arc-shaped structures. The frame 71 is threadedly connected to the exhaust port 6 through the external threads 72. The filter screen 73 is located inside the exhaust port 6.

[0029] Through the above solution: By twisting the two protruding parts 75, the frame 71 can be rotated, and the frame 71 can be rotated and removed, so that the filter screen 73 can be removed and cleaned, improving the convenience of cleaning and disassembly.

[0030] It should be noted that the present utility model describes a gas pressure regulator with remote cut-off. A micro electric cylinder 51 is firmly embedded in the inner wall of the extension part 4 by means of a support frame 52, and its telescopic end is fixed to an adjusting member 54. Once the micro electric cylinder 51 is activated, it will drive the adjusting member 54 to perform precise up and down displacement, thereby effectively compressing or relaxing the spring inside the pressure regulator, achieving remote precise control of the regulator, and greatly facilitating the instant cut-off and opening operations of the gas. In addition, three sealing rings 53 are carefully installed on the outer surface of the adjusting member 54, significantly enhancing its sealing performance when sliding inside the extension part 4 and ensuring the tightness of the system operation. Since the frame 71 is tightly thread-connected to the inner wall of the exhaust port 6 through its external thread 72, this design enables the filter screen 73 inside the frame 71 to be easily installed and removed. When the filter screen 73 accumulates dust and affects the use, the user can quickly remove it for cleaning, effectively preventing the blockage of the exhaust port 6 caused by dust accumulation. Two convex parts 75 are provided on the inner wall of the frame 71. These two convex parts 75 not only enhance the structural strength of the frame but also play a key role during the rotation operation, greatly improving the smoothness of the twisting rotation of the frame 71, enabling the operator to easily and labor-savingly perform maintenance or replace the filter screen, and significantly improving the work efficiency and operation experience.
