Description

Technical Field

[0001] This utility model relates to the field of natural gas transmission technology, and in particular to a skid-mounted outlet valve assembly for natural gas stations. Background Technology

[0002] Natural gas, as a clean energy source, is in increasing demand worldwide. Natural gas stations are a key link in the production, storage, and distribution of natural gas, requiring skid-mounted outbound valve assemblies. These skid-mounted outbound valve assemblies are used for natural gas transportation and regulation, primarily for controlling and protecting the flow and pressure of natural gas. By integrating multiple valves, pipelines, instruments, and control systems, the skid-mounted valve assembly forms a complete, modular unit, facilitating installation, commissioning, and maintenance, ensuring that natural gas is delivered to downstream users under safe and stable conditions.

[0003] Existing skid-mounted outbound valve assemblies used in natural gas stations integrate multiple valves, pipelines, and instrumentation components into a single module. The excessive compactness of these components makes maintenance, repair, and replacement difficult. Furthermore, the dense arrangement of components hinders heat dissipation, particularly affecting electronic instruments and control systems, which may malfunction due to overheating. When used in natural gas stations in different regions, skid-mounted outbound valve assemblies may encounter extreme weather conditions, and low temperatures may cause gas condensation or valve freezing, affecting the stable operation of the equipment. In addition, some skid-mounted valve assembly designs lack sufficient safety devices and effective measures to cope with pipeline overpressure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a skid-mounted outlet valve assembly for natural gas stations.

[0005] This utility model is achieved by the following technical solution: a skid-mounted outlet valve group for a natural gas station, characterized in that it includes a skid-mounted platform, a support frame, a temperature control mechanism, and a conveying mechanism;

[0006] The skid-mounted platform is fixedly connected to the support frame, the temperature control mechanism is installed on the skid-mounted platform, and the conveying mechanism is connected to the support frame;

[0007] The temperature control mechanism includes a water tank, which is equipped with a heating device. The water tank is connected to a water pump, the water pump's output end is connected to a water delivery pipe, and a nozzle is provided at the outlet of the water delivery pipe. The water tank is fixedly connected to ribs.

[0008] Optionally, the water supply pipe is fixedly connected to the skid-mounted platform, and a fixing block is fixedly connected to the support frame, with the water supply pipe being fixedly connected to the fixing block.

[0009] Optionally, the conveying mechanism includes an inlet pipe, a transition pipe, an outlet pipe, a return pipe, and a check valve. The inlet pipe is fixedly connected to the support frame and is connected to a shut-off valve. One end of the inlet pipe is fixedly connected to an inlet gate valve, and the other end is fixedly connected to one end of the return pipe. The other end of the return pipe is fixedly connected to the outlet pipe. The return pipe is fixedly connected to the check valve, and the outlet pipe is fixedly connected to an outlet gate valve. Both ends of the transition pipe are fixedly connected to the inlet pipe and the outlet pipe, respectively. A safety valve is fixedly connected to the transition pipe, and a pressure gauge is fixedly connected to the outlet pipe.

[0010] Optionally, the air intake pipe is fixedly connected to the skid-mounted platform via a support block.

[0011] Optionally, a filter is provided on the air intake pipe.

[0012] Optionally, a reflux regulating valve is provided on the reflux pipe.

[0013] Optionally, the intake pipe is equipped with a shut-off valve, and the outlet pipe is equipped with a pressure reducing valve.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model uses a water tank to control the ambient temperature. In hot weather, to ensure the structural safety and normal operation of the device, a water pump draws water from inside the tank through a pumping pipe and delivers it to the nozzles through a water supply pipe, cooling the device and its surrounding environment. This prevents the sealing gaskets at pipe and valve connections from expanding due to excessive temperature, which could affect their sealing performance. In cold weather, a heating device is activated to heat the water stored inside the tank, transferring heat to the surroundings through fins to prevent valves and pipes from freezing. This ensures the normal operation of the device, prevents the equipment from being affected by the external environment, extends its service life, and improves the device's practicality.

[0016] This invention employs a conveying mechanism, specifically a multi-stage control system using an inlet gate valve and a shut-off valve, to ensure the device responds to abnormal situations and prevent accidents. An inlet regulating valve in the middle of the inlet pipeline precisely regulates the flow and pressure of natural gas, ensuring normal equipment operation. A filter removes impurities from the natural gas, preventing equipment damage. Natural gas enters the transition pipeline through the inlet pipeline, passes through a safety valve, and enters the outlet pipeline. When the gas pressure is too high, the safety valve opens, releasing gas to the pressure relief end and into the return pipeline to prevent system hazards. A pressure gauge in the middle of the outlet pipeline monitors the internal pressure, and a pressure reducing valve lowers the high pressure of the natural gas to a suitable low pressure level for transportation or use, ensuring the device's effectiveness. Simultaneously, gas entering the return pipeline passes through a check valve, preventing backflow and also preventing gas from the inlet pipeline from impacting the safety valve through the return pipeline, ensuring device reliability. The return regulating valve controls the pressure of the return gas entering the transition pipeline, preventing excessive pressure on the transition pipeline and ensuring the device's practicality.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-5 This embodiment of a skid-mounted outlet valve assembly for a natural gas station includes a skid-mounted platform 1, a support frame 3, a temperature control mechanism 4, and a conveying mechanism 6. The skid-mounted platform 1 is fixedly connected to the support frame 3, the temperature control mechanism 4 is mounted on the skid-mounted platform 1, and the conveying mechanism 6 is connected to the support frame 3. The temperature control mechanism 4 includes a water tank 401, a heating device 402, a water pump 404 connected to the water tank 401, a water pump 404 connected to the water pump 404, a water delivery pipe 405 connected to the output end of the water pump 404, a nozzle 406 at the outlet of the water delivery pipe 405, and a rib 407 fixedly connected to the water tank 401.

[0027] With the above-mentioned device, in hot weather, in order to ensure the structural safety and normal use of the device, the water pump 404 draws water from the inside of the water tank 401 through the water pumping pipe 403, and delivers it to the nozzle 406 through the water delivery pipe 405 to spray it out, thereby cooling the device and the surrounding environment and preventing the sealing gaskets at the pipe valve connection from expanding due to excessive temperature and affecting the sealing performance. In cold weather, the heating device 402 is activated to heat the water stored inside the water tank 401, and heat is transferred to the surroundings through the fins 407 to prevent the valves and pipes from freezing, ensuring the normal use of the device, preventing the equipment from being affected by the external environment, extending the service life, and improving the practicality of the device.

[0028] In one exemplary embodiment, the water supply pipe 405 is fixedly connected to the skid-mounted platform 1, and a fixing block 5 is fixedly connected to the support frame 3, with the water supply pipe 405 fixedly connected to the fixing block 5.

[0029] In one exemplary embodiment, the conveying mechanism 6 includes an inlet pipe 601, a transition pipe 606, an outlet pipe 608, a return pipe 612, and a check valve 614. The inlet pipe 601 is fixedly connected to the support frame 3 and is connected to a shut-off valve 603. One end of the inlet pipe 601 is provided with an inlet gate valve 602, and the other end is connected to one end of the return pipe 612. The other end of the return pipe 612 is connected to the outlet pipe 608. The return pipe 612 is fixedly connected to the check valve 614. The outlet pipe 608 is connected to an outlet gate valve 611. The two ends of the transition pipe 606 are respectively connected to the inlet pipe 601 and the outlet pipe 608. The transition pipe 606 is provided with a safety valve 607, and the outlet pipe 608 is provided with a pressure gauge 609.

[0030] In this embodiment, multi-stage control via the inlet gate valve 602, outlet gate valve 611, and shut-off valve 603 ensures the device can respond in abnormal situations and prevent accidents. Natural gas enters through the inlet pipe 601, passing sequentially through the transition pipe 606, safety valve 607, and outlet pipe 608. When the gas pressure is too high, the safety valve opens, releasing gas to the pressure relief end into the return pipe 612 to prevent system hazards. A pressure gauge 609 installed in the middle of the outlet pipe 608 monitors the internal pressure of the pipe. The pressure gauge 609 detects the natural gas pressure in the pipe in real time. When the pressure is too high, the safety valve 607 activates, sending natural gas into the return pipe 612. The gas entering the return pipe 612 passes through the check valve 614. The check valve 614 prevents gas backflow and also prevents gas from the inlet pipe 601 from impacting the safety valve 607 through the return pipe 612, ensuring the reliability of the device.

[0031] In one exemplary embodiment, an intake pipe 601 is fixedly connected to a support block 2, and the support block 2 is fixedly connected to the skid-mounted platform 1.

[0032] In one exemplary embodiment, an air intake duct 601 is provided with a filter 605, which is used to filter impurities in the natural gas to prevent the impurities from damaging the equipment.

[0033] In one exemplary embodiment, a reflux regulating valve 613 is provided on the reflux conduit 612.

[0034] In this embodiment, the reflux regulating valve 613 is used to control the pressure of the reflux gas entering the transition pipe 606, preventing the transition pipe 606 from being subjected to excessive pressure and ensuring the practicality of the device.

[0035] In one exemplary embodiment, the air intake pipe 601 is provided with an air intake regulating valve 604, and the air outlet pipe 608 is provided with a pressure reducing valve 610.

[0036] In this embodiment, an intake regulating valve 604 is installed in the middle section of the intake pipe 601 to precisely regulate the flow and pressure of natural gas; a pressure reducing valve 610 is installed on the outlet pipe 608 to reduce the high pressure of natural gas to a low pressure level suitable for transportation or use, thereby ensuring the effectiveness of the device.
