ventilation valve

A ventilation valve is a valve on a turbocharged engine system that separates exhaust gases from the turbine. The separation of exhaust gas reduces the speed of the turbine and correspondingly lowers the speed of the compressor. The main function of the ventilation valve is to stabilize the propulsion pressure of the turbocharging system to protect the engine and turbocharger. The ventilation valve is controlled by the ventilation valve transmission device, and the rotating device is controlled by the pressure of the intake manifold.

Ventilation valves are often designed and manufactured using a new structural form of welding midline disc plates and short structural steel plates. They are compact, lightweight, easy to install, have low flow resistance, high flow capacity, avoid the influence of high temperature expansion, and are easy to operate. No connecting rods, bolts, etc. inside the body, reliable operation, and long service life. It can be installed in multiple workstations without being affected by the flow direction of the medium.

purpose

Used for gas pipelines in the sulfuric acid industry: inlet and outlet of furnace front blower, inlet and outlet of relay blower, series and connecting valves for electric mist removal, inlet and outlet of SO2 main blower, converter adjustment, inlet and outlet of preheater, etc., for regulating and cutoff gas volume.

Used in the sulfur burning, conversion, and dry absorption sections of sulfur based sulfuric acid systems, it is the preferred brand of valves for sulfur based sulfuric acid plants. It is widely regarded by users as having good sealing performance, light operation, secondary corrosion, high temperature resistance, easy and flexible operation, safe and reliable use, and has been widely promoted and used.

It is also widely used as a regulating and shut-off device in pipelines for media such as SO2, steam, air, gas, ammonia, CO2, oil products, water, salt water, alkali solution, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid, etc. in industries such as chemical, petrochemical, smelting, pharmaceutical, and food.
