Insulation discharge valve is mainly used for reactors, tanks and other containers in the bottom of the discharge, discharge, sampling, and no dead zone off operation, phosphorus and phosphorus light medium, hydrofluorocarbons, hydrochloric acid, sodium hydroxide and potassium hydroxide, suitable for all kinds of acid, alkali, salt solution and organic solvent. Easy to operate, free to open, flexible and reliable movement; valve assembly and maintenance is simple, the sealing structure is reasonable, the sealing ring replacement is convenient and practical. The structure is mainly composed of a valve body, valve, seal, valve stem, valve gland, bracket, handwheel, flanges, nuts, screws and other parts. Its main parameters are: nominal diameter DN, discharge valve rated flow coefficient KV, discharge valve nominal pressure and the pressure discharge valve body and valve component materials, discharge valve flow characteristics, discharge valve for temperature, discharge voltage and power valve control signal, with the discharge valve accessories.
