/Cast steel ammonia stop valve
Referred to as ammonia valve, cast steel ammonia stop valve is referred to as ammonia valve. It is suitable for pipelines under various working conditions such as nominal pressure and working temperature of ℃, such as petrochemical, pharmaceutical, fertilizer, electric power industry, etc. , cut off or connect the pipeline medium. Driving methods include manual gear transmission, electric pneumatic, etc. Characteristics of the stop valve for cast steel ammonia
The stop valve for cast steel ammonia must be sealed. The sealing pair structure of the stop valve for cast steel ammonia adopts a spherical plane type. The sealing is automatically compensated, which can achieve a double insurance effect and good sealing performance. Stable and without adhesive wear, it effectively solves the sealing performance problems of ordinary valves used in chemical pipelines
The through valve has poor corrosion resistance, the shell is easy to perforate, and the medium has certain characteristics. The cast steel ammonia stop valve has a valve body in The material is corrosion-resistant and can withstand the corrosion of ammonia gas and liquid ammonia, and the low temperature can be adjusted to degrees Celsius
The flange adopts a concave and convex sealing structure to ensure that the sealing of the flange is absolutely reliable under the fluctuation of pipeline pressure
The door is There will be no media leakage from the stuffing box during the service life, which eliminates the possibility that ordinary valve stuffing boxes with weak seals will easily leak out and cause accidents.
The structural characteristics and uses of the cast steel ammonia stop valve
The cover is made of Babbitt alloy, which has very good sealing performance and long service life
The through flange has a square structure and the valve stem uses an intermediate rod. The sealing surface of the connecting body is spherical and convex, and is sealed with the valve foot by a line.
