Ammonia shut-off valve, "liquid ammonia special cut-off valve" is a practical environmentally-friendly liquid ammonia shut-off valve developed by Zhang Gong, a senior engineer of Shanghai Five-Yuan Valve Factory Technology Development Department. The invention is based on liquid ammonia and ammonia storage. The assembly, adjustment and protection of the tanks provide quality assurance.
Ammonia shut-off valve, liquid ammonia special cut-off valve is a special requirement for ammonia gas medium transportation, and combined with the actual situation of domestic valve application, it is designed with novel sealing form and reliable sealing structure. Applicable to safety valves for ammonia gas storage tank/pipe inlet and outlet control to cut off flow.
Ammonia shut-off valve,
1. Aiming at the disadvantages of poor corrosion resistance and easy perforation of ordinary valves, according to the specific characteristics of the medium, the ammonia shut-off valve uses corrosion-resistant steel (carbon steel added corrosion-resistant alloy element) on the valve body material, which can resist ammonia gas. Gas corrosion, low temperature can reach -40 °C, to ensure maximum working conditions.
2. The sealing pairing structure type adopts ball, plane type, automatic compensation of seal, achieve double insurance effect, stable sealing performance, no adhesive wear, effectively solve the problem of poor sealing performance and easy leakage of ordinary valves used in chemical pipelines.
3. The flange of the product adopts the groove sealing structure, which ensures the inner flange seal is absolutely reliable even in the case of pipeline pressure fluctuation.
4. The multi-stage PTFE sealing material is used in the upper sealing device to form a combined seal to ensure that the packing box has no medium leakage during the service life, which eliminates the weak seal of the ordinary valve packing box, the easy leakage of the medium, and even the accident. may. Ball Valve, globe valve, Safety Valve, Check Valve, Butterfly Valve, Strainer.
