Description

Technical Field

[0001] The invention relates to the technical field of gas equipment regulation and testing, and in particular to a gas pressure regulator debugging platform and a calibration method thereof. Background Art

[0002] The gas pressure regulating system is a device used to adjust the gas supply pressure in the gas transmission and distribution system, so that the gas pressure in the gas supply system is reduced and stabilized at a safe, economical and efficient level, and the gas pressure at the user end does not fluctuate violently with the gas consumption and upstream pressure changes. Another function of the pressure regulator is overpressure relief cut-off. When the pressure regulator fails and the outlet pressure exceeds the set value, it may cause harm to the normal operation of the user-side equipment and public safety. The equipment starts the safety relief valve to reduce the pressure; if the gas pressure still cannot be reduced to normal, or even continues to rise, the cut-off valve will work to cut off the gas supply.

[0035] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] The gas pressure regulating system is a device used to adjust the gas supply pressure in the gas transmission and distribution system, so that the gas pressure in the gas supply system is reduced and stabilized at a safe, economical and efficient level, and the gas pressure at the user end does not fluctuate violently with the gas consumption and upstream pressure changes. Another function of the pressure regulator is overpressure relief cut-off. When the pressure regulator fails and the outlet pressure exceeds the set value, it may cause harm to the normal operation of the user-end equipment and public safety. The equipment starts the safety relief valve to reduce the pressure; if the gas pressure still cannot be reduced to normal, or even continues to rise, the cut-off valve will work to cut off the gas supply. For this reason, the normal operation of the pressure regulating system is an important part of ensuring the safety of gas supply. The stability of the outlet pressure of the pressure regulator, the air tightness when closed, the relief pressure value, the pressure value of the cut-off valve, etc. are indicators to judge whether the gas pressure regulator can function normally.

[0040] The current process for replacing a pressure regulator is to shut down the gas supply, install the replacement device directly on the pipeline, and then perform leak detection and debugging. This operation process requires a long period of gas outage, which is likely to cause user complaints; if the updated equipment is found to be abnormal during the debugging process, further debugging and replacement will be required, which will greatly extend the gas outage time.

[0041] In order to shorten the gas outage time for replacing a pressure regulator, a gas pressure regulator debugging platform and a calibration method thereof are provided to facilitate pre-inspection before installation on an in-service pipeline and improve work efficiency.

[0042] Reference Figures 1 to 5The gas pressure regulator debugging platform includes: a first pipeline 100 and a fixing frame 200.

[0043] Specifically, along the air intake direction of the first pipeline 100, a first control valve 110, an inlet first test position 120 and a relief valve test position 130 are sequentially arranged.

[0044] In a specific embodiment, the relief valve test position 130 includes a plurality of connecting valves 131 connected in sequence, the inlet port diameter of each connecting valve 131 is larger than the outlet port diameter, and among two adjacent connecting valves 131, the inlet port diameter of the connecting valve 131 close to the inlet end is larger than the inlet port diameter of the connecting valve 131 far from the inlet end, and the outlet port diameter of the connecting valve 131 close to the inlet end is larger than the outlet port diameter of the connecting valve 131 far from the inlet end.

[0045] It is easy to understand that the multiple connecting valves 131 arranged in sequence have different caliber specifications and are used to adapt to different relief valves, so as to perform air tightness detection on the relief valves.

[0046] In a specific embodiment, the fixed frame 200 includes a second pipeline 210 and an adjusting frame 220, the input end of the second pipeline 210 is connected to the output end of the first pipeline 100, the adjusting frame 220 is connected to the second pipeline 210, the second pipeline 210 and the adjusting frame 220 form a pressure regulator placement position, along the air inlet direction of the second pipeline 210, the second control valve 211, the inlet second test position 212 and the inlet sealing valve 213 are arranged in sequence, and the outlet sealing valve and the outlet test position are arranged in sequence along the air inlet direction of the adjusting frame 220.

[0047] Further, the adjustment frame 220 includes a hollow end 221 and a solid end 222, and an outlet sealing valve 223 and an outlet test position 224 are sequentially arranged along the air inlet direction of the hollow end 221, and the solid end 222 is movably connected to the second pipeline 210. It is easy to understand that both the inlet sealing valve 213 and the outlet sealing valve 223 are provided with sealing gaskets.

[0048] In a specific embodiment, the adjustment frame 220 also includes an adjustment bolt 225, one end of the adjustment bolt 225 is fixedly connected to the solid end 222, and the other end of the adjustment bolt 225 is threadedly connected to the second pipe 210. The position of the adjustment frame 220 relative to the second pipe 210 is adjusted by rotating the adjustment bolt 225 to adapt to pressure regulators of different specifications.

[0049] It is easy to understand that the first control valve 110 , the second control valve 211 , the inlet sealing valve 213 , and the outlet sealing valve 223 may be flange ball valves.

[0050] In a specific embodiment, a voltage regulator inclination adjustment component is provided at the voltage regulator placement position, and the voltage regulator inclination adjustment component is used to support the bottom of the voltage regulator and adjust the inclination of the voltage regulator placement.

[0051] Specifically, the voltage regulator inclination adjustment assembly includes a support plate 310, a mounting plate 320 and an adjustment rod 330. The support plate 310 and the mounting plate 320 are connected by a rotating shaft. The mounting plate 320 is fixedly set on the fixing frame 200. A plurality of clamping positions 321 are set on the mounting plate 320. One end of the adjustment rod 330 is fixedly set on the support plate 310, and the other end of the adjustment rod 330 is fixed at the clamping position 321. By setting the adjustment rod 330 at different clamping positions 321, the change in the inclination angle of the support plate 310 relative to the mounting plate 320 can be achieved, thereby realizing the adjustment of the inclination angle of the voltage regulator.

[0052] In a specific embodiment, a connecting rod group is provided between the first pipeline 100 and the adjustment frame 220 .

[0053] Specifically, the connecting rod group includes a long rod 410 and a short rod 420, one end of the long rod 410 is fixedly arranged on the first pipe 100, and the other end of the long rod 410 is fixedly arranged on the solid end 222. One end of the short rod 420 is fixedly arranged on the fixing frame 200, and the other end of the short rod 420 is fixedly arranged in the middle of the long rod 410.

[0054] It is easy to understand that by providing the long rod 410 and the short rod 420 , the stability of the connection between the first pipe 100 and the fixing frame 200 can be enhanced.

[0055] In a specific embodiment, a disc-shaped support base 500 is provided at the air inlet end of the first pipeline 100. The disc-shaped support base 500 improves the strength of the support and disperses the force of the gas pressure regulator debugging platform.

[0056] In a specific embodiment, a calibration method is provided, using the gas pressure regulator debugging platform of any of the above embodiments, comprising the following steps:

[0057] Relief valve leak test:

[0058] Check whether the first control valve 110 and the second control valve 211 are airtight: adjust the specification of the relief valve test position according to the size of the relief valve, and install a well-sealed ball valve at the relief valve test position;

[0059] Install the pressure gauge and the balloon at the first test position 120 of the inlet, open the first control valve 110, perform air tightness test on the relief valve test position 130, and close the first control valve 110 after confirming that the air tightness is good;

[0060] Disassemble the ball valve installed on the relief valve test position 130, and install the relief valve to be tested;

[0061] Open the first control valve 110, observe the value of the pressure gauge set on the first inlet test position 120, and when the value of the pressure gauge matches the operating pressure value of the pipeline network, pressurize the pressure regulator with the balloon set on the first inlet test position 120;

[0062] After the pressurization value reaches 1.5 times the operating pressure of the pipeline network, the relief valve is tested for air tightness to prevent the relief valve that does not meet the requirements from being put into use.

[0063] In a specific embodiment, a calibration method is provided, using the gas pressure regulator debugging platform of any of the above embodiments, comprising the following steps:

[0064] Place the voltage regulator on the voltage regulator placement position, and adjust the tilt position of the voltage regulator according to the height of the voltage regulator;

[0065] The inlet of the pressure regulator is fitted with the inlet sealing valve 213, and the outlet of the pressure regulator is fitted with the outlet sealing valve 223 by adjusting the adjustment frame 220;

[0066] Install the pressure gauge and the balloon at the inlet second test position 212 and the outlet test position 224, then open the first control valve 110 and the second control valve 211 in sequence, and perform air tightness test on the outlet test position 224, the inlet first test position 120, the inlet second test position 212, the inlet sealing valve 213 and the outlet sealing valve 223 to confirm that there is no leakage point;

[0067] The gas enters the pressure regulator through the first pipeline 100 and the second pipeline 210 in sequence. The test pressure value at the inlet of the pressure regulator can be detected through the second inlet test position 212. The hexagonal nut on the top of the spring of the pressure regulator is adjusted to change the tightness of the spring, set the adjustment pressure of the pressure regulator, and observe the value of the pressure gauge at the outlet test position 224 to determine that the pressure regulation is completed.

[0068] After the test is completed, close the first control valve 110 and the second control valve 211 in sequence, open the ball valves on the inlet second test position 212 and the outlet test position 224, and disassemble the pressure regulator after no gas is discharged.

[0069] In a specific embodiment, the gas in the second pipeline 210 is pressurized by a balloon provided at the second test position 212 of the inlet, thereby setting the cut-off pressure of the pressure regulator, and adjusting the pressure regulator so that its cut-off valve closes the valve port of the pressure regulator; when setting the release pressure of the pressure regulator, the gas in the second pipeline 210 is pressurized by the balloon on the second test position 212 of the inlet, and the pressure regulator is adjusted to release the over-pressure gas to the outside.

[0070] It is easy to understand that the air tightness test involved in the embodiments of the present application can be tested with soapy water. If the soapy water bubbles, it proves that there is a leak; if there is no bubbling, it can be used normally.

[0071] It is easy to understand that the first inlet test position 120 is set because the leak test of the relief valve requires a test pressure greater than the working pressure. Therefore, a balloon can be set at the first inlet test position 120 for pressurization; and a pressure gauge is set to display the pressure value.

[0072] It is easy to understand that the relief valve is installed in the valve well. When the operation needs to discharge the gas in a certain pipe section, the buried valve can be closed to cut off the upstream gas supply, and the relief valve can be opened to discharge it to the outside.

[0073] In a specific embodiment, the outlet sealing valve includes a main frame, a connecting pipe 610 and a direction and gap adjustment mechanism 620. The main frame includes a flange blind plate 630, a main clamping column 640, a force-bearing support frame 650, and a reinforcement frame 660. The flange blind plate 630 is used for sealing, the force-bearing support frame 650 is used for auxiliary load bearing, and the reinforcement frame 660 is used to strengthen the stability of the main frame. The connecting pipe 610 is used to connect the pipeline leading to the outlet test position.

[0074] It is easy to understand that the outlet sealing valve can use a flange. When the flange clamps an object, a gap will appear, and the contact surface is prone to uneven contact. The direction and gap adjustment mechanism 620 can use a tightening sleeve, combined with bolt tightening parts, to make the clamping contact uniform and allow the outlet sealing valve to fit.

[0075] The technical solution of this application has the following advantages:

[0076] 1. Provide a debugging platform for gas pressure regulators so that the equipment can be pre-inspected before installation on the in-service pipeline to improve work efficiency;

[0077] 2. The debugging platform of the gas pressure regulator provided in the embodiment of the present application is applicable to pressure regulating devices of different sizes;

[0078] 3. The debugging platform of the gas pressure regulator provided in the embodiment of the present application can be used for the detection of the venting ball valve, thereby improving the practicality;

[0079] 4. The debugging platform for the gas pressure regulator provided in the embodiment of the present application can also be used for daily pressure regulator maintenance training, which can intuitively display the entire operation process so that operators can understand the principles, processes and technical specifications of the operation.

[0080] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
