Instrument pipe fitting valve , also called instrument valve, is a pipeline accessory. Its main function is to change the section of the passage and the flow direction of the medium, so as to control the flow of the conveying medium. The specific function analysis of instrument pipe fittings and valves is as follows:
Connecting or cutting off the medium in the pipeline: instrument valves such as gate valves, globe valves, ball valves, etc. can connect or cut off the medium in the pipeline to realize the opening and closing of the pipeline.
Adjust and control the flow and pressure of the medium in the pipeline: the flow and pressure of the medium in the pipeline can be accurately adjusted and controlled through the throttle valve, regulating valve, pressure reducing valve, safety valve and other instrument valves to meet the process requirements.
Change the flow direction of the medium in the pipeline: such as distribution valve, three-way cock, three-way or four-way ball valve, etc. These instrument valves can change the flow direction of the medium in the pipeline to realize the diversion or confluence of the medium.
Prevent the medium in the pipeline from backflow: instrument valves such as check valves and bottom valves can prevent the medium in the pipeline from backflow under specific circumstances, thus protecting the safety of equipment and pipelines.
Separation medium: instrument valves such as steam trap and air trap can separate moisture or other impurities in the medium to ensure the purity and stability of the medium.
Indication and adjustment of liquid level: such instrument valves as liquid level indicator and liquid level regulator can indicate and adjust the liquid level of medium in the pipeline to ensure the normal operation of the equipment.
