Overview
Purpose
Globe - check valve installed in combined cycle heat on the main steam pipe, prevent the backflow medium, failure occurs when the boiler, quickly close the valve by medium pressure, boiler safety protection effect.
Brief account of structure
1.The valve uses the pressure self-tightened sealing,the higher the pressure,the better the sealing performance,the seal ring uses formed asbestos packing.
2.The disc move up and down inside of the body to first lift the stem before moving and,upon the medium pressure,to let the valve automatically opened.ln case of a failure with the boiler,the valve inlet pressure lowers and the medium flows backward to quickly close the valve.
Installation instructions
1.The valve must be vertically mounted on the pipeline,with the stem upward and the medium flowing in under the seat ring.
2.Place the electric actuator in such an environment as non-corrosive non-explosive gas and with the ambient temperature-20~40℃ and the related humidity 80%.
3.For the electric actuator,when used with the pipeline of a temperature below 350℃,use semi-fluid Li-base lubricating oil(Q/SY1002-65) and,when the said temperature is higher than 350℃,use GB492-2N-4 sodium-base lubricating grease.
