1 three and unique structure of the place. Structure length is short, the length of the structure is only 1/4 ~ 1/8 of traditional flange check valves; 2. Large and small, light weight, the weight is only 1/4 ~ 1/20 of traditional flange check valves. 3. In the utility of the reset torsion spring, valve shut down more quickly and acuity, water hammer pressure is small; 4. Level pipeline or straight pipe can be used, installation is convenient; 5. Port amidst, fluid resistance small; 6. Disc hole and the Industrial Valves shaft in the preset with the reasonable transition rotating gap, increase the opening and closing the acuity of the disc and tightly closed; 7. Disc quarter-turn swing, shut off the impact of small; 8. Group of simple and compact structure closely, modelling is good; 9. The blow plugging device, dust in the valve cavity ( Formation of crystals, scarring, furring) Can regularly with high-pressure steam purging; 10. Use fixed number of year of the survival of a long and high reliable sex. Tightly closed leak: comprised tightly closed surface dust, forming crystals, scarring, furring, eliminate method signatures blowing device, can the valve tightly closed surface of high pressure steam purge regularly. Four: common accident and alleviation measures: a petition in leak-proof: Marine valve comprised a petition tightness of screw nut is not tight or not warp gasket destroyed, alleviation measures, on average, tighten the screws, cleaning away dirt, transform gasket. After choose different valve materials, can be suitable for use in carbon dioxide gas, MI, MIAII, half II, eau forte, CH3COOH, strong oxygen medium and ammonium nitrate, and other special a medium. 。 On the basis of the pure soda industry a long time experience, proposed stem carbon dioxide gas temperature at 80 ~ 100 ℃ advisable, due to the carbon stem temperature is too high, easy to cause the screw compressor failure. Second, the use of pure soda special check valve is suitable for use in the nominal pressure PN1. 0 ~ 4. 0 mpa, nominal diameter (~ 1200 mm ( NPS2~48) , office 196 ~ 540 ℃ upstream piping to avoid all media. Q: pure soda roughly describe a: special check valve is a, probably is pure soda special check valve good-looking appearance, reasonable structure of the default, the check Industrial Valves disc in fluid pressure utility under open, media from inlet to outlet side. When import pressure is lower than the export side, the disc in the reset torsion spring, fluid pressure differential and actuation closed itself factors such as gravity, to avoid the media flow. Remind: used for medium carbon dioxide gas, carbon dioxide gas temperature stem not high, due to the carbon dioxide gas gas dust easily into a hole in the mouth, lead to the disc. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
