Description

Technical Field

[0001] This utility model belongs to the field of gas transmission technology, and in particular relates to an adjustable gas pressure stabilizing device. Background Technology

[0002] Gas is a combustible gas commonly used in homes, industries, and businesses. It is typically used for heating, cooking, lighting, and industrial production. It is usually composed of natural gas, liquefied petroleum gas, and synthetic gas. To ensure the stability of gas pressure and avoid the impact of pressure fluctuations on gas equipment and systems, adjustable gas pressure regulators are used during gas transmission.

[0003] Existing adjustable gas pressure regulators have achieved good regulation of gas pressure. However, since they are often connected to gas pipelines via threads during use, and there is no leak detection mechanism at the connection, gas leaks caused by improper installation or long-term corrosion cannot be detected and repaired in time. This leads to the failure of the gas pressure regulator and affects normal use. Therefore, we provide an adjustable gas pressure regulator to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable gas pressure stabilizing device. By combining the leak detection component and the connection component, it solves the problem in the prior art that adjustable gas pressure stabilizing devices do not have a leak self-detection mechanism at the connection point, which leads to the inability to detect gas leaks in a timely manner and affects the normal use of the pressure stabilizing device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to an adjustable gas pressure stabilizing device, comprising a pressure stabilizing pipe, a fixing ring fixedly connected inside the pressure stabilizing pipe, a pressure regulating plate disposed inside the fixing ring, and a first pressure gauge fixedly connected to the top of the pressure stabilizing pipe; a leak detection component is disposed on one side of the pressure stabilizing pipe, the leak detection component comprising a sealing shell located on the surface of the pressure stabilizing pipe, a second pressure gauge fixedly connected to the top of the sealing shell; a connecting component is disposed on one side of the pressure stabilizing pipe, the connecting component comprising a connecting pipe located inside the sealing shell, and a gas delivery pipe threadedly connected to the surface of the connecting pipe; a drive adjustment component is disposed at the top of the pressure stabilizing pipe, the drive adjustment component comprising a bracket fixedly connected to the pressure stabilizing pipe, and a rotating rod disposed at the bottom of the bracket, the opening and closing degree of the pressure regulating plate being adjusted by the drive adjustment component.

[0007] The present invention is further configured such that the leakage detection component includes a sealing airbag, the sealing airbag is fixedly connected to the sealing shell, the sealing shell is provided with a fixing cylinder inside, a spring is fixedly connected to one side of the fixing cylinder, a piston plate is fixedly connected to one side of the spring, a connecting frame is fixedly connected to one side of the piston plate, and a conduit communicates between the fixing cylinder and the sealing airbag.

[0008] The present invention is further configured such that the drive adjustment component also includes a motor, the motor is fixedly connected to the bracket, a fixed rod is fixedly connected to the output end of the motor, a drive wheel is fixedly connected to the surface of the fixed rod, and a driven wheel is engaged on one side of the drive wheel.

[0009] The present invention is further configured such that the pressure stabilizing tube is fixedly connected to the sealing shell, and the bottom of the rotating rod passes through the fixing ring and is fixedly connected to the pressure regulating plate.

[0010] The present invention is further configured such that the top of the rotating rod is movably connected to the bracket, and a control button is fixedly connected to the top of the bracket.

[0011] The present invention is further configured such that the piston plate is in contact with the fixed cylinder, and one side of the connecting frame penetrates the fixed cylinder.

[0012] The present invention is further configured such that the bottom of the pressure regulating plate is in contact with the fixing ring, and the connecting pipe is connected to the voltage stabilizing pipe.

[0013] The present invention is further configured such that a first detection probe is fixedly connected to the bottom of the first pressure gauge, and a second detection probe is fixedly connected to the bottom of the second pressure gauge.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model connects to a gas delivery pipeline via a connecting pipe to form a gas delivery channel. When the gas delivery pipeline is threaded onto the surface of the connecting pipe, it continuously forces the gas inside the fixed cylinder into the sealing bladder, causing the sealing bladder to inflate and expand, making it tightly contact the gas delivery pipeline. This creates a sealed cavity between the sealing shell and the gas delivery pipeline. When the value of the second pressure gauge changes, the sealing at the connection point becomes problematic, allowing for timely repairs and ensuring the normal operation of the pressure stabilizing device.

[0016] 2. This utility model uses a drive motor to rotate a fixed rod, which in turn drives a rotating rod and a pressure regulating plate to rotate as a whole via a drive wheel and a driven wheel. This adjusts the tilt angle of the pressure regulating plate, changing the degree of opening and closing between it and the fixed ring, thereby making the two first pressure gauges read the same value. This achieves the purpose of electric pressure stabilization, ensuring a constant pressure when gas is delivered into the gas equipment, and protecting the gas equipment. Attached Figure Description

A conduit 16 connects the fixing cylinder 12 and the sealing airbag 11. The drive adjustment assembly also includes a motor 17, which is fixedly connected to the bracket 9. A fixing rod 18 is fixedly connected to the output end of the motor 17, and the surface of the fixing rod 18 is fixedly connected to... There is a drive wheel 19, with a driven wheel 20 meshing on one side of the drive wheel 19. The pressure stabilizing pipe 1 is fixedly connected to the sealing shell 5. The bottom of the rotating rod 10 passes through the fixing ring 2 and is fixedly connected to the pressure regulating plate 3. The top of the rotating rod 10 is movably connected to the bracket 9. The top of the bracket 9 is fixedly connected to the control button. The piston plate 14 is in contact with the fixed cylinder 12. One side of the connecting frame 15 passes through the fixed cylinder 12. The bottom of the pressure regulating plate 3 is in contact with the fixing ring 2. The connecting pipe 7 is connected to the pressure stabilizing pipe 1. The bottom of the first pressure gauge 4 is fixedly connected to the first detection probe. The bottom of the second pressure gauge 6 is fixedly connected to the second detection probe.

[0030] Specifically: the sealing airbag 11 is located on the surface of the gas transmission pipe 8 and is in close contact with it to seal the sealing shell 5; the fixed cylinder 12 is fixedly connected to the pressure stabilizing pipe 1; the connecting frame 15 is in contact with the gas transmission pipe 8; the driven wheel 20 is fixedly connected to the surface of the rotating rod 10; the bottom of the first detection probe penetrates the pressure stabilizing pipe 1; the bottom of the second detection probe penetrates the sealing shell 5; the first detection probe is fixedly connected to the pressure stabilizing pipe 1; and the second detection probe is fixedly connected to the sealing shell 5.

[0032] During normal gas delivery, the motor 17 drives the fixed rod 18 to rotate, which in turn drives the rotating rod 10 and the pressure regulating plate 3 to rotate as a whole through the driving wheel 19 and the driven wheel 20. This adjusts the tilt angle of the pressure regulating plate 3, thereby adjusting the opening and closing degree between the pressure regulating plate 3 and the fixed ring 2. This ensures that the readings of the first pressure gauges 4 on both sides are the same, guaranteeing stable gas pressure for the gas equipment. This protects the gas equipment and makes it more convenient for people to use.
