The J14B internal thread Angle type ammonia stop valve features stable sealing performance, safe and reliable operation, strong corrosion resistance, no internal or external leakage of medium, and easy operation. It successfully solves the problems of poor corrosion resistance, easy perforation of the shell, poor sealing performance and easy leakage of ordinary valves used in chemical pipelines. It is particularly suitable for the transmission of ammonia gas and gas pipelines in the chemical industry. And it meets the requirements of long-term reliable use, including its sealing performance, maintainability, safety, etc.
Product Features
In view of the shortcomings of ordinary valves, such as poor corrosion resistance and easy perforation of the shell, the ammonia gas-specific valve selects corrosion-resistant steel (low-temperature carbon steel with added corrosion-resistant alloy elements) for the valve body material according to the specific characteristics of the medium. It can resist the corrosion of ammonia gas and liquid ammonia, and the low temperature can reach -40℃, ensuring the usage requirements of the working conditions to the greatest extent.
2. The sealing pair structure type of the ammonia stop valve adopts spherical and flat types. The sealing is automatically compensated to achieve a double insurance effect. The sealing performance is stable, with no adhesive wear. It effectively solves the problem of poor sealing performance and easy leakage of ordinary valves used in chemical pipelines.
3. The middle flange of the product adopts a concave-convex sealing structure, ensuring the absolute reliability of the middle flange seal even when the pipeline pressure fluctuates.
4. The upper sealing device adopts multi-stage polytetrafluoroethylene sealing materials to form a combined seal, ensuring that there is no medium leakage in the stuffing box of the valve during its service life. This eliminates the possibility of weak sealing in the stuffing box of ordinary valves, easy leakage of the medium, and even causing accidents.
