The liquid ammonia shut-off valve is specially designed for ammonia or gas pipelines or installations. Structural attention to fire prevention requirements. The packing is made of polytetrafluoroethylene with reliable sealing and absolute leakage. The sealing materials are made of polytetrafluoroethylene or nylon, which are soft sealing and reliable. Suitable for ammonia, liquefied petroleum gas pipeline system, as an opening and closing device, but also suitable for other temperature < 80 C pipeline.
Liquid ammonia globe valve has the characteristics of stable sealing performance, safe and reliable use, strong corrosion resistance, no medium inside, leakage and easy operation. It successfully solves the problems of poor corrosion resistance, easy perforation of shell, poor sealing performance and easy leakage of ordinary valves for chemical pipelines, especially for ammonia and gas pipelines in chemical industry. The transmission of the road and meeting the requirements of long-term reliable use. Its sealing, maintainability, safety and so on.
Product characteristics:
1. In view of the shortcomings of ordinary valve such as poor corrosion resistance and easy perforation of the shell, according to the specific characteristics of the medium, special ammonia valve uses corrosion-resistant steel (carbon steel with corrosion-resistant alloy elements), which can resist ammonia gas and liquid ammonia corrosion, and the low temperature can be up to - 40 C, to ensure the maximum operating conditions.
2. The sealing pair of liquid ammonia globe valve adopts ball and plane type, and the sealing can be compensated automatically. The sealing effect is double insurance. The sealing performance is stable and non-adhesive wear and tear, which effectively solves the problem of poor sealing performance and easy leakage of ordinary valve used in chemical pipeline.
3. The flange in the product adopts mortise groove sealing structure, which ensures the absolute reliability of the middle flange seal even in the case of pipeline pressure fluctuation.
4. The multistage PTFE sealing material is used in the upper sealing device to form a combined seal, which ensures that the packing box of the valve has no medium leakage during the service life, and eliminates the possibility of weak sealing of the ordinary packing box of the valve, easy leakage of the medium, and even accidents.
Product standard:
Liquid ammonia shut-off valves are set up on the basis of GB/T12235 standards. The material selection and structure design of the enterprise standard are completely based on the corrosion characteristics of chlorine gas and liquid chlorine medium and the working conditions. The technical parameters are superior to the national standard.
