Description

Technical Field

[0001] This utility model relates to the field of gas construction technology, and in particular to a gas pipeline pressure regulating and metering device. Background Technology

[0002] With the continuous growth of urban gas demand and the development of gas engineering, the safe and stable operation of gas transmission systems has become a crucial issue. Pipeline pressure regulating and metering devices, as a key component in the gas transmission process, are responsible for regulating the gas pressure within the pipeline to ensure that gas transmission remains safe, efficient, and controllable.

[0003] However, the installation of gas pipeline pressure regulating and metering devices is not very convenient. Because ensuring the sealing of pipe connections is crucial, the alignment between pipes must be precise during installation. Traditional installation methods often involve manually lifting and connecting the pipes, which presents several problems. For example, metal gas pipelines are generally heavy, requiring significant manual labor for lifting, resulting in long installation times and low efficiency. Furthermore, the connection and commissioning processes must be done manually, compromising the accuracy of the pipe joints and causing significant time commitment for adjustments. Therefore, a gas pipeline pressure regulating and metering device is proposed. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-5 This utility model provides a gas pipeline pressure regulating and metering device, which includes a base 1. The bottom of the base 1 is fixedly connected to an anti-slip pad, and the upper side is fixedly connected to a telescopic rod 2. The anti-slip pad improves the overall stability of the device. The outer tube of the telescopic rod 2 is fixedly connected to two sides with spring pins 9, and the inner tube is provided with matching pin holes 10 on both sides. The height of the mounting base 3 can be easily adjusted under the action of the spring pins 9. The upper end of the telescopic rod 2 is connected to the mounting base 3, and the lower two ends of the mounting base 3 are fixedly connected to rubber pads 31. The rubber pads 31 prevent collision between the mounting base 3 and the telescopic rod 2, thus ensuring good safety.

[0025] Mounting block 4 is fixedly connected to the bottom of mounting base 3. Mounting block 4 is hinged to telescopic rod 2. Telescopic rod 2 is cuboid. Mounting block 4 has a through hole 41 in the middle. Mounting block 4 has several protrusions 42 on the outside of the through hole 41. The protrusions 42 are arranged in an arc shape. The upper end of telescopic rod 2 has an opening 21. The inner wall of opening 21 has a slot 22. The outer side is threaded with a bolt 23. There are several slots 22, which correspond one-to-one with the protrusions 42. Mounting block 4 is located inside opening 21 and is adapted to opening 21. Mounting block 4 on the upper side of protrusion 42 has a scale arrow 43. Under the action of scale arrow 43, it is easy to adjust the angle of mounting base 3. At the same time, under the action of protrusion 42 and slot 22, it is easy to fix the angle of mounting base 3.
