Manifold system
Standard:
The valve group is combined with the actual production environment conditions and process requirements of domestic iron and steel enterprises, strictly comply with GB16912-1997 "Oxygen and related gas safety technical regulations" standards, design and develop combined instrument valve products, with the advantages of safety, reliability, high efficiency and energy saving, especially suitable for the metallurgical industry on the pressure stability and flow regulation of oxygen, gas control process.
Function;
Detection and regulation of gas flow, monitoring of pressure (main pipe and outlet). Safety protection devices, etc.
Compose:
The oxygen valve station is divided into two sets of pipeline systems: main pipeline and branch pipeline. The main pipe of the oxygen valve station is composed of quick cut valve group, pressure measuring device, filter device, sewage discharge device, etc., which ensures the normal safety work of the system to the greatest extent; It is used to connect the oxygen supply pipes in the workshop and distribute oxygen to the branch lines. Each branch of the oxygen valve station is composed of a shut-off valve, a quick shut-off valve, a pressure reducing valve, a flow regulating valve, a pressure transmitter, a flame retardant and a flow meter; All valve bodies are made of stainless steel; All pipes are made of 304 stainless steel pipe; Used to provide a monitorable and adjustable oxygen flow to the oxygen gun. Each furnace wall gun is supplied with oxygen by two oxygen valve station branch pipelines: main oxygen + auxiliary oxygen.
The gas valve station is also divided into main pipeline, branch pipeline sleeve pipeline system. The main pipe of the gas valve station is composed of routing gas inlet pipe and nitrogen inlet quick-cut valve group, and inlet pipe routing pressure measuring device, filtration device, sewage discharge device, etc.; To the greatest extent to ensure the normal safety of the system; It is used to connect the workshop gas supply pipes and distribute gas to the branch lines. Each route of the gas valve station is composed of globe valve, quick shut-off valve, pressure reducing valve, flow regulating valve, pressure transmitter, flame retardant and flow meter. Used to provide a monitorable and regulated gas flow for furnace wall oxygen guns.
The control of each gas in the valve station is individually controlled by PLC and pneumatic actuator. The main valve body of the pipeline adopts domestic high-quality products, and the flowmeter adopts the orifice plate flowmeter of the Ganges. The system is equipped with a measuring device for measuring the gas pressure of the pipe network and a pipe network adjustment device for adjusting the gas flow, and at the same time plays the role of compensating and controlling the orifice flowmeter, so that when the pressure of the pipe network fluctuates, the flow measurement value is compensated. Gas flow binning setting for continuous or intermittent oxygen blowing, this system is equipped with remote control of the console installed in the main control room.
The valve frame system consists of oxygen main circuit (one way), main oxygen (7 way), epoxy (5 way); The main gas pipeline (including gas inlet pipe and nitrogen inlet pipe) and branch gas pipeline (2 ways) are composed.
The gas inlet pipe of the gas line is used for the introduction of gas, and it is used by the oxygen gun on the furnace wall of the 2-way branch pipeline. The nitrogen inlet pipe of the gas line is used for the introduction of nitrogen, and it is supplied to the 2-way gas branch line for purging the gas line, and purging before and after using the gas.
Peculiarity:
1 Each channel can simulate and adjust the flow size;
2 Each way has an anti-tempering device;
3 Each channel has a flow pressure detection device;
4 Each channel can be controlled individually on the screen.
