Description

Technical Field

[0001] The utility model relates to the technical field of pressure reduction and regulation, and specifically, to a skid-mounted gas pressure reduction and regulation device. Background Art

[0002] A gas pressure reduction and regulation device is a key component in a gas supply system, responsible for safely and stably reducing the high-pressure gas to a low-pressure state suitable for gas equipment. This device can not only control the gas flow rate, but also ensure that the gas is smoothly reduced in pressure from a high-pressure source such as a pipeline or a gas cylinder, and maintain the output pressure within a stable range, thereby ensuring the normal operation of gas equipment and the safety of users. Through such functions, the gas pressure reduction and regulation device greatly improves the safety and reliability of gas transmission and use, and becomes an important part for safety guarantee and performance optimization in the gas supply system.

[0003] Traditional gas pressure reduction and regulation devices rely on the physical mechanism of gas flow to work. After high-pressure gas enters the pressure regulator, the pressure reduction valve undertakes the regulation task and gradually reduces the gas pressure to the required low-pressure level. However, such devices usually rely on a simple pore structure to achieve the pressure reduction function, which to a certain extent limits their ability to accurately control the flow rate and pressure during gas discharge, and it is difficult to achieve continuous and fine adjustment of the output pressure and flow rate. This may not only reduce the gas use efficiency, but also, under extreme working conditions, may cause equipment damage or instability of the operating environment due to excessive pressure fluctuations, thus increasing potential safety hazards.

With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model.

[0029] According to an embodiment of the present utility model, a skid-mounted gas pressure reducing and regulating device is provided.

[0030] Now, the present utility model will be further described in combination with the accompanying drawings and specific implementation manners. As Figures 1-7 shown, the skid-mounted gas pressure reducing and regulating device according to an embodiment of the present utility model includes a fixed plate 1. On one side of the inner wall of the fixed plate 1, two groups of first support rods 2 are provided. On the other side of the inner wall of the fixed plate 1, two groups of second support rods 3 are provided. At the top of the first support rod 2, a first fixed seat 4 is provided. The bottoms of the two groups of first fixed seats 4 are connected by a gas inlet pipe 5. At the top of the first fixed seat 4, a first connecting pipe 6 is provided.

The second connecting pipe 9 and the first connecting pipe 6 are matched by an adjusting assembly 11.

[0031] With the above technical solution of the present utility model, through the coordinated action of the gas inlet pipe 5, the first connecting pipe 6, the adjusting assembly 11, the second connecting pipe 9, the pressure reducing assembly 10 and the gas outlet pipe 8, a skid-mounted structure of the gas pressure reducing and regulating device is realized, reducing the workload of on-site assembly and installation. This not only improves work efficiency but also enhances the stability and reliability of the device, making the installation and commissioning process smoother and more efficient. By setting the pressure reducing assembly 10, an adaptive pressure reduction and regulation of the gas pressure in the pipeline is achieved, effectively avoiding potential damage to the gas pressure reducing and regulating device caused by violent fluctuations in gas pressure. At the same time, it also eliminates the adverse effects on the use effect, helps to extend the service life of the entire gas pressure reducing and regulating device, and ensures the stability and reliability of gas supply. By setting the adjusting assembly 11, the regulation accuracy of the gas pressure in the pipeline is enhanced, achieving a delicate adjustment of the gas pressure, ensuring that the output gas pressure is accurately maintained within a predetermined range, effectively reducing potential problems caused by pressure fluctuations, not only improving the accuracy of the gas pressure reducing and regulating device but also providing a strong guarantee for the stable operation and efficient use of the gas supply system.

[0032] In one embodiment, for the above-mentioned second connecting pipe 9, a pressure gauge 12 is provided at the top of the second connecting pipe 9, so as to accurately obtain the gas pressure value inside the pipeline and improve work efficiency.

[0033] In one embodiment, for the above-mentioned first connecting pipe 6, one end of the first connecting pipe 6 is connected to the adjusting assembly 11 through a first flange 13, and the other end of the second connecting pipe 9 is connected to the adjusting assembly 11 through a second flange 14, so as to realize the installation and disassembly of the adjusting assembly 11 and extend the service life of the gas pressure reducing and regulating device.

[0034] In one embodiment, for the above-mentioned pressure reducing assembly 10, the pressure reducing assembly 10 includes a first pressure reducing pipe 1001 disposed between two groups of second connecting pipes 9. Two groups of electric valves 1002 are symmetrically arranged at the top of the first pressure reducing pipe 1001. The middle part of the first pressure reducing pipe 1001 is connected to a second pressure reducing pipe 1003, so as to control the automatic discharge of gas pressure and increase the pressure reduction rate.

[0035] In one embodiment, for the above-mentioned pressure reducing assembly 10, the pressure reducing assembly 10 further includes a pressure reducing cylinder plate 1004 disposed on the inner wall of the second connecting pipe 9. An adjusting seat 1005 is arranged inside the pressure reducing cylinder plate 1004. A through hole 1006 matching the first pressure reducing pipe 1001 is opened on one side of the pressure reducing cylinder plate 1004, so as to realize the adaptive pressure reduction and regulation of the gas pressure in the pipeline and extend the service life of the gas pressure reducing and regulating device.

[0036] In one embodiment, for the above-mentioned adjusting seat 1005, the adjusting seat 1005 includes an adjusting ring one 10051 and an adjusting ring two 10052 arranged inside the decompression cylinder plate 1004. The adjusting ring one 10051 and the adjusting ring two 10052 are connected by a number of groups of springs one 10053. On one side of the adjusting ring two 10052, there is a baffle 10054. On one side of the baffle 10054, a decompression hole 10055 matching the through hole 1006 is provided, thus effectively avoiding potential damage to the gas pressure reducing and regulating device caused by violent fluctuations in gas pressure.

[0037] The working principle of the decompression component 10 is as follows: When the gas pressure in the connecting pipe two 9 is too high, the excess gas pressure exerts a certain extrusion on the adjusting ring two 10052. The adjusting ring two 10052 slides inside the connecting pipe two 9, and the adjusting ring two 10052 squeezes the spring one 10053. During the compression of the spring one 10053, the baffle 10054 moves along with the adjusting ring two 10052. When the decompression hole 10055 coincides with the through hole 1006, the excess gas pressure is discharged through the decompression pipe one 1001 and the decompression pipe two 1003, thus ensuring the stability inside the connecting pipe two 9. In addition, by controlling the electric valve 1002 through the controller, the discharge of gas pressure can be controlled, improving the working efficiency.

[0038] In one embodiment, for the above-mentioned adjusting component 11, the adjusting component 11 includes a housing one 1101 arranged between the flange one 13 and the flange two 14. At the top of the housing one 1101, there is a housing two 1102. Inside the housing two 1102, there is a threaded rod 1103. On the circumferential outer side of the threaded rod 1103, there is an adjusting plate 1104. At the bottom end of the threaded rod 1103, there is a sealing plug one 1105. The sealing plug one 1105 and the adjusting plate 1104 are matched through a spring two 1106. At the bottom end of the sealing plug one 1105, there is a connecting shaft 1107. On the circumferential outer side of the top of the connecting shaft 1107, there is a sealing plug two 1108. At the bottom end of the connecting shaft 1107, there is a sealing plug three 1109, thus enhancing the regulation accuracy of the gas pressure inside the pipeline and realizing the delicate adjustment of the gas pressure.

[0039] The working principle of the adjusting component 11 is as follows: When it is necessary to adjust the gas pressure, by rotating the threaded rod 1103 to drive the adjusting plate 1104 to rise and fall, the adjusting plate 1104 drives the sealing plug one 1105 to rise and fall through the spring two 1106. The sealing plug one 1105 drives the sealing plug two 1108 and the sealing plug three 1109 to rise and fall respectively through the connecting shaft 1107. The sealing plug one 1105, the sealing plug two 1108 and the sealing plug three 1109 adjust the size of the air holes inside the housing one 1101, thus reducing the gas pressure from the connecting pipe one 6 to the connecting pipe two 9. In addition, due to the self-locking characteristic of the threaded rod 1103, the safety during the working process is improved.

[0040] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0041] In actual application, the gas is transported through the gas inlet pipe 5, via the connecting pipe 1 6, the regulating component 11, the connecting pipe 2 9 and the gas outlet pipe 8. When the gas pressure is too high, the controller controls the pressure reducing component 10 to achieve automatic pressure reduction of the gas (the working principle of the pressure reducing component 10 is as shown above), thereby improving the performance and life of the gas pressure reducing regulating device; at the same time, by adjusting the regulating component 11 (the working principle of the regulating component 11 is as shown above), the gas pressure can be accurately adjusted, thereby improving the accuracy of the gas pressure reducing regulating device.

[0042] In summary, with the help of the above technical solution of the utility model, through the synergistic effect of the gas inlet pipe 5, the connecting pipe 1 6, the regulating assembly 11, the connecting pipe 2 9, the pressure reducing assembly 10 and the gas outlet pipe 8, the skid-mounted structure of the gas pressure reducing regulating device is realized, which reduces the workload of on-site assembly and installation, not only improves the work efficiency, but also enhances the stability and reliability of the device, making the installation and commissioning process smoother and more efficient. By setting the pressure reducing assembly 10, the adaptive pressure reducing regulation of the gas pressure in the pipeline is realized, and the potential damage to the gas pressure reducing regulating device caused by the drastic fluctuation of the gas pressure is effectively avoided. At the same time, the adverse effect on the use effect is also eliminated, which helps to extend the service life of the entire gas pressure reducing regulating device and ensure the stability and reliability of the gas supply. By setting the regulating assembly 11, the control accuracy of the gas pressure in the pipeline is enhanced, the fine adjustment of the gas pressure is achieved, and the output gas pressure is ensured to be accurately maintained within the predetermined range, which effectively reduces the potential problems caused by the pressure fluctuation, not only improves the accuracy of the gas pressure reducing regulating device, but also provides a strong guarantee for the stable operation and efficient use of the gas supply system.
