With the continuous development of industry, the production process is more comprehensive and more complex, and the variety of process pipelines is more and more. Applications to meet process requirements are also becoming more and more widespread. In general, other pipelines except a domestic water supply pipeline, a fire fighting pipeline and a rainwater discharge pipeline in a factory can be drawn into a process pipeline, such as pipelines required for producing circulating water, compressed air, steam, nitrogen, coal gas, sulfuric acid, alkali liquor, ammonia water, ammonia gas and the like.
Gas supply is an important link in process piping. Gases are widely needed in the fields and industries of biopharmaceuticals, electronic semiconductors, laboratories, energy station systems, medical treatment, chemical industry, petroleum and the like. The gas types include bulk gases such as nitrogen, argon, oxygen, hydrogen and the like, and also include flammable, explosive and corrosive gases such as silane, phosphane, acetylene, ethylene and the like. The existing gas supply pipeline is designed in a pipeline engineering mode and is constructed and installed on site. The gas supply pipeline supplies gas with stable quantity and pressure according to the characteristics and requirements of the gas. The general design is that the gas supply pipeline is connected with the gas source, a valve is arranged on the gas supply pipeline, and gas connected out from the gas source is directly supplied through a valve switch. However, when a local fault occurs in the gas supply pipeline, the process pipeline needs to be integrally disassembled; and the air supply pipeline only supplies air through a valve switch, and can not supply air and release pressure when the pressure is insufficient or exceeds, so that the air supply pipeline is not suitable for occasions with high air supply precision requirements.

Example 2
As shown in fig. 1, a gas supply pressure adjusting device for process pipeline, be responsible for 1 including the gas supply, the gas supply is responsible for 1 and is connected first adjusting valve 2, first adjusting valve 2 is connected monitoring pipeline 3, install pressure transmitter 4 on the monitoring pipeline 3, carry out pressure monitoring through pressure transmitter 4, 3 end position connection process pipeline interfaces 5 of monitoring pipeline, still connect pressure release pipeline 6 through the tee bend interface between first adjusting valve 2 and the monitoring pipeline 3, second adjusting valve 7 is connected to pressure release pipeline 6, second adjusting valve 7 is connected with exhaust interface 8 and is exhausted.
Preferably, the pressure transmitter 4 is placed in the monitoring pipe 3 near the outlet.
Preferably, the first regulating valve 2, the second regulating valve 7 are electric valve devices, and signal feedback can be performed between the pressure transmitter 4 and the electric valve devices.
The process flow and the working principle of the invention are as follows: when the device is used for adjusting the air supply pressure, the main air supply pipe 1 is connected with an air source and starts to supply air to the monitoring pipeline 3. The pressure transmitter 4 monitors the pipeline pressure value and performs real-time signal feedback. When the pressure value of the monitoring pipeline 3 does not reach the required parameters, a signal is fed back to the first adjusting valve 2 to adjust the opening degree and supplement air. When the pressure value of the monitoring pipeline 3 reaches the required parameter, a feedback signal is sent to the first adjusting valve 2 to stop opening adjustment, and the stability of the air flow pressure is kept. When the pressure value of the monitoring pipeline 3 exceeds the required parameter, a second regulating valve 7 arranged on the pressure relief pipeline 6 regulates the opening degree for pressure relief; when the device carries out pressure monitoring, the pressure transmitter 4 feeds back the pressure value of the monitoring pipeline 3. The end position of the monitoring pipeline 3 is connected with a process pipeline interface 5, and the process pipeline is a required gas supply pipeline. Because the monitoring pipeline 3 is communicated with the process pipeline through the process pipeline interface 5, the pressure value fed back by the pressure transmitter 4 on the monitoring pipeline 3 can be regarded as the process pipeline pressure value, and the process pipeline pressure value is taken as the gas regulation basis.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
