Description

Technical Field

[0001] This utility model relates to the technical field of pipeline pressure stabilizing devices, specifically to a pressure stabilizing device for the inlet and outlet pipelines of a gas compressor. Background Technology

[0002] In the process of gas transportation, gas compressors play a crucial role in increasing gas pressure and ensuring the gas transportation distance and flow rate. However, due to fluctuations in the gas source, the instability of the compressor's own operation, and changes in the gas demand of downstream users, the pressure in the inlet and outlet pipelines of the gas compressor often fluctuates significantly.

[0003] Unstable pressure not only affects the normal delivery of gas, leading to production interruptions, but may also cause safety accidents such as pipeline ruptures and gas leaks. Furthermore, pressure fluctuations negatively impact the lifespan of gas compressors, increasing equipment maintenance costs. Traditional pressure stabilization methods rely primarily on manual valve adjustment, which is slow to respond and lacks precision, failing to meet the stable gas pressure requirements of modern industrial production. Therefore, this device provides pressure stabilization devices for the inlet and outlet pipelines of the gas compressor. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a pressure stabilizing device for the inlet and outlet pipelines of a gas compressor, thereby solving the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: a pressure stabilizing device for the inlet and outlet pipelines of a gas compressor, including a gas supply pipeline of a gas compressor, a valve seat fixedly installed on one side of the gas supply pipeline of the gas compressor, and a control box fixedly installed at the bottom of the valve seat;

[0006] The valve seat is provided with an air outlet pipe at the top, and a bypass pipe is fixedly installed on one side of the air outlet pipe and the gas compressor supply pipe. A connecting flange is fixedly installed above the valve seat, the air outlet pipe and the bypass pipe.

[0007] A slide rod is slidably mounted on the inner side of the valve seat, and a valve body is fixedly mounted on the outer side of one end of the slide rod.

[0008] As a further improvement to the above solution, a first motor is fixedly installed on one side of the control box, a first drive shaft is fixedly installed at the output end of the first motor, and a transmission gear is fixedly installed on the outer side of the first drive shaft.

[0009] As a further improvement to the above solution, a movable block is fixedly installed on the outer side of one end of the slide rod, and a toothed groove is opened on one side of the movable block, and the transmission gear meshes with the toothed groove.

[0010] As a further improvement to the above solution, a fixed base is fixedly installed on the outside of the bypass pipe, a second motor is fixedly installed on one side of the fixed base, a second drive shaft is fixedly installed at the output end of the second motor, and a butterfly valve body is fixedly installed on the outside of the second drive shaft.

[0011] As a further improvement to the above solution, a pressure stabilizing module is installed above the control box, and multiple high-precision pressure sensors are fixedly installed above the gas supply pipeline of the gas compressor. The pressure stabilizing module and the high-precision pressure sensors are electrically connected.

[0012] As a further improvement to the above solution, the voltage regulator module is electrically connected to a PLC controller, and the PLC controller is electrically connected to the first motor and the second motor.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] 1. To quickly adjust pipeline pressure in emergencies, a bypass pipeline is installed above the gas supply and outlet pipelines of the gas compressor. A butterfly valve body is installed on the bypass pipeline. When the pipeline pressure is too high, the second motor can be controlled to drive the second drive shaft and the butterfly valve body to rotate. After the butterfly valve body rotates, the bypass pipeline can be opened, allowing some gas to be discharged through the bypass pipeline and reducing the pipeline pressure. When the pressure returns to normal, the butterfly valve body automatically closes.

[0015] 2. The voltage stabilizing module uses a PLC controller as the core control unit. The PLC controller receives the pressure signal from the high-precision pressure sensor and calculates the valve opening degree according to the preset pressure range and control algorithm, and sends control commands to the first motor and the second motor. The PLC controller also has fault diagnosis and alarm functions. When a fault occurs in the system, it can issue an alarm in time and display fault information to facilitate maintenance personnel to troubleshoot and handle the problem. Attached Figure Description
