Description

Technical Field

[0001] This utility model relates to the field of gas pressure regulator technology, specifically an indirect-acting gas pressure regulator. Background Technology

[0002] Indirect-acting gas pressure regulators are key devices in gas transmission and distribution systems used to stabilize downstream gas pressure. Their core feature is the precise control of gas pressure achieved by adjusting the main valve opening through indirect control (using auxiliary energy or pilot pressure signals). Compared to direct-acting regulators, they offer advantages such as higher regulation accuracy, a wider flow range, and adaptability to complex operating conditions. They are widely used in medium- and high-pressure, high-flow-rate gas supply scenarios, including city gas gate stations, regional pressure regulating stations, and industrial enterprises.

[0003] Existing patent document CN113944789B discloses an indirect-acting gas pressure regulator, comprising a valve body with a threaded opening at the top, a valve cover threaded into the threaded opening, and a pressure regulating assembly mounted on the valve cover and detachably connected at its bottom to the valve port inside the valve body. The pressure regulating assembly includes a sleeve threaded onto the valve port and communicating with the lower cavity of the valve body; an intake box fixedly mounted on the upper surface of the valve cover and communicating at its bottom with an elastic exhaust hood, the top of which is connected to the lower cavity of the valve body via a throttle valve and a pipe; a diaphragm positioned above the sleeve and slidably connected to the sleeve via a connecting rod; a spring and an elastic exhaust hood fixed to the upper surface of the diaphragm and fixed to the valve cover; and an exhaust funnel fixed to the lower surface of the diaphragm and limited to sliding on the outer wall of the sleeve at its bottom. The design of the elastic exhaust hood, diaphragm, and exhaust funnel combined and sliding on the sleeve in this invention extends the movable pressure regulating distance of the diaphragm, greatly increasing the flow capacity.

[0004] However, existing indirect-acting gas pressure regulators, such as electric indirect-acting gas pressure regulators, usually require a power supply and rely entirely on external power. If there is a power outage, line fault, or power module failure, the regulator may lose its pressure regulation capability, leading to uncontrolled downstream pressure. This is especially risky in scenarios without backup power, resulting in poor adaptability of the gas pressure regulator. To address this, we propose an indirect-acting gas pressure regulator.

[0016] (III) Beneficial Effects

[0017] This utility model provides an indirect-acting gas pressure regulator, which has the following advantages:

[0018] This type of indirect-acting gas pressure regulator, through its generator, rotating shaft, and rotating blades, allows gas to flow. As the gas flows, it acts on the rotating blades, causing them to rotate via the rotating shaft. This rotation of the shaft generates electricity, which is then transmitted through power lines to charge a lithium battery. The gas pressure regulator can then use the power generated by the gas flow to power the generator components, producing electricity in real time without relying on an external power source. This ensures the regulator's pressure regulation capability and improves its adaptability. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: an indirect-acting gas pressure regulator, comprising,

[0026] The bearing unit 1 includes a pressure regulator body 101. The pressure regulator body 101 has two integrally formed conveying pipes 102 on both sides. One of the conveying pipes 102 has an integrally formed mounting base 105 on the top. The top of the mounting base 105 is threadedly connected to a fixing cap 106. A generator 107 is mounted on the top of the fixing cap 106. The drive end of the generator 107 is fixed to a rotating shaft 109 through a coupling. A rotating blade 110 is mounted on the outside of the rotating shaft 109. A pressure sensor 111 is threadedly connected to the top of the other conveying pipe 102.

[0027] The regulating unit 2 includes a fixed tube 201 integrally formed on the top of the pressure regulator body 101. The top of the fixed tube 201 is threadedly connected to a tube cap 202. A telescopic rod 203 is installed on the top of the tube cap 202. A controller 204 is installed on the top of the telescopic rod 203. A lithium battery 207 is installed inside the controller 204. A control button 205 and a pressure display 206 are embedded on the top of the controller 204.

[0028] Furthermore, one end of the conveying pipe 102 is integrally formed with a docking flange 103, and a docking interface 104 is provided on one side of the docking flange 103. The installation can be completed by installing the pipe on the docking flange 103, then inserting bolts into the docking interface 104 and fixing the bolts.

[0029] Furthermore, the output terminal of the generator 107 is electrically connected to a transmission line 108, which is electrically connected to the controller 204. Through the transmission line 108, the electricity generated by the generator 107 can be transferred to the lithium battery 207.

[0030] Furthermore, the output terminal of the pressure sensor 111 is electrically connected to a data line 112, which is electrically connected to the controller 204. Through the data line 112, the pressure detected by the pressure sensor 111 can be transmitted to the display position.

[0031] Furthermore, the regulator body 101 has an integrally formed valve seat 113 inside, and a valve port 114 is opened in the center of the valve seat 113, through which gas can be circulated as needed.

[0032] Furthermore, a sealing plate 208 is installed at the bottom of the telescopic rod 203, and a sealing plug 209 is integrally formed at the bottom of the sealing plate 208. When the pressure is too high, the telescopic rod 203 drives the sealing plate 208 and the sealing plug 209 to move downward. At this time, the sealing plug 209 enters the valve port 114. When the gas flow is too low or the pressure is too low, the telescopic rod 203 drives the sealing plate 208 and the sealing plug 209 to move upward, thereby controlling the opening size of the valve port 114, so that the pressure regulator can control and adjust the opening of the main valve according to the demand.

[0033] Working Principle: After installation, first check the installation, fixation, and safety features of this utility model. The operator sets the gas flow pressure using control button 205 as needed. Pressure sensor 111 detects the pressure. When the pressure is too high, the telescopic rod 203 moves the sealing plate 208 and sealing plug 209 downwards, allowing the sealing plug 209 to enter the valve port 114. When the gas flow is too low or the pressure is too low, the telescopic rod 203 moves the sealing plate 208 and sealing plug 209 upwards, thus controlling the opening of valve port 114. This allows the pressure regulator to adjust the main valve opening as needed. This invention achieves precise control of gas pressure. When gas flows, it acts on the rotating blade 110, which rotates via the rotating shaft 109. The generator 107 generates electricity due to the rotation of the shaft 109, which is then transmitted through the transmission line 108 to the lithium battery 207, charging it. This allows the gas pressure regulator to generate power through the gas flow, driving the generator components to produce electricity in real time without relying on an external power source. This completes the application of this invention. The invention has a simple structure and is safe and convenient to use.

[0034] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
