Past the coke oven of coking plant of high pressure ammonia water injection system structure of high and low voltage conversion system generally adopts the traditionaI-type three-way ball valve,due to the working conditions of the parts of the special,I-type three-way ball valve leak in installed for months or even a few days,to reduce the system pressure,leakage of high pressure ammonia will be pulverized coal to gas collector absorption,coke oven chamber negative pressure caused by severe,affecting both the coke quality,rigor and furnace.Because the valve is installed on the top of the coke oven,high temperature,poor working conditions,each part of the body of valve replacement to bring very great difficulty.The frequent replacement of the valve, also caused great economic losses to the factory,and also seriously pollute the environment.
◆ Characteristics Modular three-way valve in addition to the general ball valve fluid resistance small,open/close quickly,as well as good sealing performance,modular three-way valve adopts integral structure design,simple,compact,lightweight,durable,compared with the commonly used two style ball valves,cancelled in the middle of the two bolt connecting flange,to reduce the leakage point,seal is more reliable.Enhanced ptfe seat,high voltage,better heat resistance, wear resistance,long service life.
