[0002] As a core infrastructure for urban energy transmission and industrial gas production, gas pipelines use pressure regulating devices as key equipment to ensure stable gas pressure and safe operation of downstream equipment. These devices are widely used in residential buildings, medium-sized commercial facilities, and industrial furnaces.

[0003] Existing gas pipeline pressure stabilization devices mostly adopt integrated fixed structures with fixed vent pipe heights, resulting in poor safety adaptability. They cannot be flexibly adjusted according to environmental changes and rely on the natural emission mode of the vent valve and vent pipe to discharge gas. There is no active auxiliary exhaust mechanism, which makes it impossible to quickly discharge gas leaks in the box. Utility Model Content

[0004] The main purpose of this utility model is to provide a gas pipeline pressure stabilization and regulation device, which can effectively solve the technical problems of the existing gas pipeline pressure stabilization and regulation devices having a fixed and non-adjustable vent pipe height and limited exhaust speed due to the lack of an active auxiliary exhaust mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A gas pipeline pressure stabilization and regulation device includes a pressure regulating box. The bottom of the pressure regulating box is connected to an inlet pipe and an outlet pipe. One end of the inlet pipe inside the pressure regulating box is connected to a filter, and the end of the filter away from the inlet pipe is connected to a pressure regulating valve. The end of the pressure regulating valve away from the filter is connected to a venting valve. The outlet pipe is fixedly connected to the end of the venting valve away from the pressure regulating valve, and a pressure relief pipe is connected to the outside of the venting valve. A venting mechanism connected to the top of the pressure relief pipe is installed on the top of the pressure regulating box.

[0006] As a further embodiment of this utility model, a switch door is movably installed at the front of the pressure regulating box, and an observation window is embedded in the switch door.

[0007] As a further embodiment of this utility model, a jacket layer is provided on the inner rear side of the pressure regulating box, and a refrigeration pipe is installed in the jacket layer. One end of the refrigeration pipe passes through the top of the pressure regulating box and is connected to a water inlet pipe, and the other end of the refrigeration pipe passes through the top of the pressure regulating box and is connected to a water outlet pipe.

[0008] As a further embodiment of this utility model, an explosion-proof fan is fixedly installed at the rear of the pressure regulating box. The air inlet of the explosion-proof fan is located inside the pressure regulating box, and an exhaust pipe is connected to the outside of the explosion-proof fan. One end of the exhaust pipe located inside the pressure regulating box is connected to a guide pipe, and the guide pipe is fixedly connected to the pressure relief pipe.

[0009] As a further embodiment of this utility model, a one-way valve is installed on the air guide pipe, and when the refrigeration pipe is installed in the jacket layer, space is reserved for the air inlet of the explosion-proof fan.

[0010] As a further embodiment of this utility model, the venting mechanism includes several fixed pipes and corrugated pipes connected alternately. A flame arrester is fixedly installed at the top of the top fixed pipe, and a windproof cap is fixedly connected to the top of the flame arrester. A fixed plate is fixedly connected to the outside of one of the fixed pipes, and a sleeve plate is fixedly connected to the side of the fixed plate away from the fixed pipe. A vertical plate is sleeved on the outside of the sleeve plate. An electric actuator is provided on the side of the vertical plate away from the fixed plate. A side plate is fixedly connected to the side of the sleeve plate away from the fixed plate. The top of the electric actuator is fixedly connected to the bottom surface of the side plate. A stabilizing plate for stabilizing the electric actuator is fixedly installed on the side of the vertical plate away from the fixed plate.

[0011] As a further embodiment of this utility model, a support pad is fixedly installed at the bottom end of the electric actuator, and the support pad is fixedly installed on the top surface of the pressure regulating box.

[0012] As a further embodiment of this utility model, the vertical plate has a sleeve groove inside, and the sleeve plate is sleeved inside the sleeve groove and slidably connected with the sleeve groove.

[0013] As a further embodiment of this utility model, the vertical plate is arranged parallel to the electric push rod, and the top surface of the vertical plate is fixedly connected to the top surface of the pressure regulating box.

[0014] As a further embodiment of this utility model, the pressure relief pipe penetrates the top surface of the pressure regulating box and is fixedly connected to the bottommost fixed pipe.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model, by setting an adjustable venting mechanism, allows the sleeve plate to move upward and pull the fixed tube under the drive of the electric actuator, thereby causing the corrugated pipe to extend. This allows the length of the venting pipe composed of the corrugated pipe and the fixed pipe to be flexibly adjusted according to the usage environment, making it convenient to adjust the venting pipe to a safe discharge height according to the actual situation. By installing an explosion-proof fan, the leaked gas is drawn in and sent into the inlet pipe, then into the gas guide pipe, and finally into the pressure relief pipe. As the corrugated pipe and fixed pipe discharge outward, the leaked gas inside the pressure regulating box can be quickly discharged outward, preventing gas leakage. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-5 As shown, a gas pipeline pressure stabilization and regulation device includes a pressure regulating box 1. The bottom of the pressure regulating box 1 is connected to an inlet pipe 2 and an outlet pipe 3. One end of the inlet pipe 2 located inside the pressure regulating box 1 is connected to a filter 5, and the end of the filter 5 away from the inlet pipe 2 is connected to a pressure regulating valve 13. The end of the pressure regulating valve 13 away from the filter 5 is connected to a venting valve 14. The outlet pipe 3 is fixedly connected to the end of the venting valve 14 away from the pressure regulating valve 13, and a pressure relief pipe 7 is connected to the outside of the venting valve 14. A venting mechanism 4 connected to the top of the pressure relief pipe 7 is installed on the top of the pressure regulating box 1.

[0020] The front of the pressure regulating box 1 is equipped with a movable door, and an observation window is embedded in the door. The door facilitates opening the interior of the pressure regulating box 1 for maintenance.

[0021] A jacket layer is provided on the inner rear side of the pressure regulating box 1. A refrigeration pipe 10 is installed in the jacket layer. One end of the refrigeration pipe 10 passes through the top of the pressure regulating box 1 and is connected to the water inlet pipe 11. The other end of the refrigeration pipe 10 passes through the top of the pressure regulating box 1 and is connected to the water outlet pipe 12.

[0022] Water is supplied through an external water source connected to the inlet pipe 11, then enters the cooling pipe 10, and finally exits from the outlet pipe 12. The inlet pipe 11 continuously supplies water, thereby dissipating heat inside the pressure regulating box 1.

[0023] An explosion-proof fan 8 is fixedly installed at the rear of the pressure regulating box 1. The air inlet of the explosion-proof fan 8 is located inside the pressure regulating box 1, and an exhaust pipe 9 is connected to the outside of the explosion-proof fan 8. One end of the exhaust pipe 9 located inside the pressure regulating box 1 is connected to a guide pipe 6, and the guide pipe 6 is fixedly connected to the pressure relief pipe 7. A one-way valve is installed on the guide pipe 6. When the refrigeration pipe 10 is installed in the jacket layer, space is reserved for the air inlet of the explosion-proof fan 8.

[0024] When a gas leak occurs inside the pressure regulating box 1, the leaked gas is drawn in by the explosion-proof fan 8 and then sent into the discharge pipe 9. It then enters the gas guide pipe 6 and is sent into the pressure relief pipe 7 through the gas guide pipe 6, and is discharged outward with the venting mechanism 4.

[0025] The venting mechanism 4 includes several fixed pipes 401 and corrugated pipes 402 connected alternately. A flame arrester 403 is fixedly installed at the top of the top fixed pipe 401, and a windproof cap 404 is fixedly connected to the top of the flame arrester 403. A fixed plate 410 is fixedly connected to the outside of one of the fixed pipes 401, and a sleeve plate 408 is fixedly connected to the side of the fixed plate 410 away from the fixed pipe 401. A vertical plate 405 is sleeved on the outside of the sleeve plate 408. An electric push rod 407 is provided on the side of the vertical plate 405 away from the fixed plate 410. A side plate 409 is fixedly connected to the side of the sleeve plate 408 away from the fixed plate 410. The top of the electric push rod 407 is fixedly connected to the bottom surface of the side plate 409. A stabilizing plate 406 for stabilizing the electric push rod 407 is fixedly installed on the side of the vertical plate 405 away from the fixed plate 410.

[0026] A support pad is fixedly installed at the bottom end of the electric actuator 407. The support pad is fixedly installed on the top surface of the pressure regulating box 1. A sleeve groove is opened inside the vertical plate 405. The sleeve plate 408 is sleeved inside the sleeve groove and slidably connected with the sleeve groove. The vertical plate 405 is arranged parallel to the electric actuator 407, and the top surface of the vertical plate 405 is fixedly connected to the top surface of the pressure regulating box 1. The pressure relief pipe 7 passes through the top surface of the pressure regulating box 1 and is fixedly connected to the bottommost fixed pipe 401. The electric actuator 407 extends, lifting the side plate 409, which in turn drives the sleeve plate 408 to pull the fixed tube 401, causing the corrugated tube 402 to extend, thereby changing the overall height of the corrugated tube 402 and the fixed tube 401.

[0027] It should be noted that this utility model is a gas pipeline pressure stabilization and regulation device. In use, the gas enters the filter 5 through the gas inlet pipe 2 for filtration, then enters the pressure regulating valve 13 for pressure regulation, and then passes through the vent valve 14. The vent valve 14 discharges the overpressure gas to the outside, and then discharges it through the water outlet pipe 12. The pressure regulating valve 13 and the vent valve 14 work together to stabilize and regulate the pressure.

[0028] The gas discharged from the vent valve 14 enters the vent pipe composed of the bellows 402 and the fixed pipe 401 through the pressure relief pipe 7 and is discharged outward. Since the bellows 402 is stretchable, it is extended by the electric push rod 407, which lifts the side plate 409, drives the sleeve plate 408 to move upward and pulls the fixed pipe 401, causing the bellows 402 to extend, thereby changing the overall height of the bellows 402 and the fixed pipe 401, so that the entire vent pipe can be flexibly adjusted to a suitable safe discharge height according to the usage environment.

[0029] When a gas leak occurs inside the pressure regulating box 1, the leaking gas is drawn in by the explosion-proof fan 8 and then sent into the discharge pipe 9. It then enters the gas guide pipe 6 and is sent into the pressure relief pipe 7. The gas is discharged outward through the corrugated pipe 402 and the fixed pipe 401. After being processed by the flame arrester 403 and the windproof cap 404, it is finally discharged into a safe area.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
