Combined three way valve
Formerly, various coking plants adopted the traditional structure with L type 3 way ball valve in high pressure ammonia water sprayed circulatory system. Due to the special operation condition, this causes the L type 3 ways ball valve wear out in few months, even in several days, of which causes frequent replacement for valve and serious pollution. The high pressured ammonia water attracts the coal powder to the collecting pipe, of which creates a serious negative pressure in the carbonization room and also affects the coke quality and the hermetic- ness of the furnace body.
