Description

Technical Field

[0001] This utility model belongs to the field of gas transmission and pressure regulation technology, specifically a city gas pressure regulating and transmission device. Background Technology

[0002] In urban gas supply systems, gas pressure regulation and transmission are crucial for ensuring a safe and stable gas supply. With rapid urbanization and a growing number of gas users, the complexity of gas pipeline networks and the demand for gas are constantly increasing. Gas pressure regulating devices, as key equipment in the gas transmission system, are responsible for adjusting high-pressure gas to a suitable low-pressure state for users, while also ensuring the safety and stability of the gas transmission process. However, existing urban gas pressure regulating and transmission devices still have some shortcomings in practical applications.

[0003] Currently available gas pressure regulating devices are typically complex in structure, have high installation and maintenance costs, and are slow to respond to fluctuations in gas flow or pressure, easily leading to unstable gas supply. Furthermore, some pressure regulating devices are prone to deterioration in sealing performance and reduced pressure regulation accuracy after prolonged operation, increasing the risk of gas leaks and posing a potential threat to user safety. At the same time, existing devices have low flexibility in adapting to different operating conditions, making it difficult to meet the diverse operating conditions of modern urban gas pipeline networks.

[0004] Therefore, in view of the problems existing in the existing technology, there is an urgent need to design a new type of urban gas pressure regulating and transmission device to improve the pressure regulation accuracy and response speed, enhance the reliability and safety of the equipment, and reduce maintenance costs, so as to better meet the needs of urban gas supply. Utility Model Content

[0005] The purpose of this utility model is to provide a city gas pressure regulating and delivery device, solving the problems mentioned in the background art. The city gas pressure regulating and delivery device mainly consists of: a pressure regulating box, a pressure regulating component disposed within the pressure regulating box, and a filter unit disposed on one side of the pressure regulating box. The pressure regulating box is the main structure, and both the pressure regulating component and the filter unit are mounted on the pressure regulating box. The pressure regulating component is movably connected to the pressure regulating box via a sliding seat, which drives the pressure regulating component to move vertically within the pressure regulating box. A screw is provided inside the sliding seat, and a knob connected to the screw is provided on the outside of the sliding seat. The knob drives the screw to rotate, which, in conjunction with a guide rail inside the pressure regulating box, allows the sliding seat to move vertically within the pressure regulating box. A guide rail matching the screw is provided inside the pressure regulating box, allowing the sliding seat to move longitudinally within the pressure regulating box in conjunction with the screw. The filtration unit includes a housing, a filter element disposed inside the housing, and an exhaust valve disposed at the top of the housing. The exhaust valve is inverted "T" shape, with a top opening forming an exhaust channel. The bottom filter element is fixed inside the housing by gravity, forming a lower support point, allowing filter element replacement without additional tools, greatly simplifying maintenance. The housing has an air inlet corresponding to the air inlet end of the filter element, allowing gas to smoothly enter the filter element for filtration. The exhaust valve is "T" shaped, with a side opening similar in structure to the safety pressure relief valve of a gas pipeline. A sealing ring is provided on the side of the filter element away from the housing, and the surface of the sealing ring has an elastic coating. The sealing ring and the elastic coating make the filter element and housing more tightly and stably bonded. This utility model provides a compact and rationally designed urban gas pressure regulating and transmission device that can be widely used in urban gas pipeline networks. The filtration unit purifies the gas, and the pressure regulating component allows for precise pressure control. Adjusting the position of the pressure regulating component by turning a knob not only greatly improves pressure regulation accuracy but also increases safety and optimizes urban gas transmission efficiency.

[0010] This utility model provides a city gas pressure regulating and transmission device with a compact and reasonable structural design, which can be widely used in city gas pipeline networks and has the functions of gas purification and precise pressure regulation. The following description, in conjunction with the appendix... Figure 1 To be continued Figure 3 The specific embodiments of this utility model will be described in detail.

[0011] like Figure 1 As shown, the urban gas pressure regulating and transmission device of this utility model mainly includes a pressure regulating box 1, a pressure regulating component 2, and a filter unit 7. The pressure regulating box 1, as the main structure, undertakes the support and protection functions of the entire device. The pressure regulating component 2 is installed inside it, while the filter unit 7 is located on one side of the pressure regulating box 1. The pressure regulating component 2 is movably connected to the pressure regulating box 1 via a sliding seat 3. This connection method allows the pressure regulating component 2 to move vertically within the pressure regulating box 1, thereby achieving flexible adjustment of the gas pressure. The design of the sliding seat 3... Figure 2 The diagram provides a more detailed view, showing an internal screw 4 and a knob 5 on the outside of the sliding seat 3, directly connected to the screw 4. When the operator rotates the knob 5, the screw 4 rotates accordingly, cooperating with the guide rail 6 inside the pressure regulating box 1 to move the sliding seat 3 up and down. This mechanical transmission structure is simple and reliable, effectively ensuring the position adjustment accuracy of the pressure regulating component 2, thus providing a guarantee for pressure control during gas transmission.

[0012] The filter unit 7 is located on one side of the pressure regulating box 1, and its main function is to purify the gas entering the pressure regulating box 1. For example... Figure 3 As shown, the filter unit 7 includes a housing 8, a filter element 9, and an exhaust valve 10. The housing 8 is the main body of the filter unit 7, and the filter element 9 is installed inside it to filter impurities in the gas. The filter element 9 is fixed in the housing 8 by gravity and can be replaced without additional tools, which greatly simplifies maintenance. The exhaust valve 10 is located at the top of the housing 8. The exhaust valve 10 is inverted "T" shape, with an opening at the top forming an exhaust channel and the bottom connecting to the filter element 9. The side opening of the exhaust valve 10 is similar in structure to the safety pressure relief valve of a gas pipeline, which can relieve pressure when the gas pressure is too high, thereby further improving the safety performance of the device. In addition, the housing 8 is also provided with an air inlet 11, the position of which corresponds to the air inlet end of the filter element 9, ensuring that the gas can smoothly enter the filter element 9 for filtration.

[0013] To further improve the sealing performance of the filter unit 7, a sealing ring 12 is provided on the side of the filter element 9 away from the housing 8, and the surface of the sealing ring 12 is coated with an elastic coating 13. The combination of the sealing ring 12 and the elastic coating 13 not only makes the connection between the filter element 9 and the housing 8 tighter and more stable, but also effectively prevents gas leakage, thereby ensuring the safety of the device operation. At the same time, the design of the sealing ring 12 also takes into account the convenience of actual use. Its installation and removal do not require complicated tools, making it easy for maintenance personnel to quickly complete the replacement operation.

[0014] In practical applications, the working principle of this urban gas pressure regulating and conveying device is as follows: First, gas enters the filter unit 7 from the external pipeline, enters the housing 8 through the air inlet 11, and undergoes preliminary purification treatment through the filter element 9. During this process, the filter element 9 effectively removes solid particles and impurities from the gas, thereby improving the purity of the gas. Subsequently, the purified gas enters the pressure regulating box 1 through the exhaust valve 10. At this time, the operator can adjust the position of the sliding seat 3 by rotating the knob 5 on the pressure regulating component 2, thereby changing the height of the pressure regulating component 2 in the pressure regulating box 1. Since the up and down movement of the sliding seat 3 is achieved through the cooperation of the screw 4 and the guide rail 6, the height of the pressure regulating component 2 can be precisely controlled, thereby achieving precise adjustment of the gas pressure. After pressure regulation is completed, the gas is output from the pressure regulating box 1 and enters the subsequent gas pipeline network, completing the entire conveying process.

[0015] In practical implementation, the advantages of this utility model are reflected in the following aspects: First, the design of the pressure regulating component 2 being movably connected to the pressure regulating box 1 via the sliding seat 3 makes the pressure regulating process more flexible and precise. Through the operation of the knob 5, the operator can adjust the position of the pressure regulating component 2 at any time according to actual needs, thereby meeting the gas pressure requirements in different scenarios. Second, the design of the filter unit 7 fully considers the convenience of maintenance. The filter element 9 is fixed inside the housing 8 by gravity, and can be replaced without additional tools, which not only reduces maintenance costs but also shortens maintenance time. Furthermore, the application of the sealing ring 12 and its elastic coating 13 further improves the sealing performance of the device, effectively preventing gas leakage. Finally, the structural design of the exhaust valve 10 draws on the principle of a gas pipeline safety pressure relief valve, enabling timely pressure relief when the gas pressure is too high, thus providing double protection for the safe operation of the entire device.

[0016] In summary, this utility model's urban gas pressure regulating and transmission device achieves efficient purification and precise pressure regulation of gas through the coordinated operation of the pressure regulating box 1, pressure regulating component 2, and filter unit 7. Its compact structure and reasonable design allow for wide application in urban gas pipeline networks, not only improving gas transmission efficiency but also significantly enhancing system safety and reliability. (See attached diagram.)

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
