氯气截止阀主要是针对氯气、液氯以及各类高危险介质专用而设计的。它的密封除填料外还增加了波纹管密封，从而具有双重密封结构，能有效的阻止危险介质的泄漏。在结构上，阀瓣与阀座密封副采用了耐强腐蚀的聚四氟乙烯和司太立硬质合金，密封性能稳定、使用安全可靠、耐腐蚀性强、无介质内、外漏以及操作轻便等特点。其密封性、可维修性、安全性等主要技术指标达到世界知名产品的水平。
Design Standard
Design and inspection standards:GEST89/140, GEST06/318, GB/T12235, JB/T9092.
Application
Chlorine Globe Valve with Bellows isdesigned to use in hazardous working environments. Such as medium that arecorrosive, flammable, toxic, volatile, radioactive or precious fluid medium.
The most commonly used in the followingconditions:
C12 temperaturerange from 40° to 120°C
HCl, HF, COCl2,VCM, EDC, MDI, TDI, HDI, and other fluid of similar characteristics.
Feature
corrugated pipe
a. The corrugated pipe is hidden in thevalve cover to prevent medium erosion.
b. The multilayer hydraulic formedcorrugated pipe.
c. Service life over 10000 times uses(fully opening to fulling closing).
Stem and packing
a. Additional sealing with gland Metal filler
b. Axial Alignment along the whole strokeof the stem
c. The gland filler depth is more than 2times the stroke, which effectively prevents the contact of chlorine and water.
Valve body and valve cover
a. The valve body and the valve cover arewholly forged or casted, the wall thickness exceeds higherthe standardrequirements.
b. No welding at the pressure bearingportion points.
c. The flange gasket position is completelyfixed, preventing damage to the sealing surface bypushing out of the gasket.
Sealing surface
a. The cone shape seal, low torque.
b. Solid carbide integral hard facing,offering excellent corrosive resistant feature and low cost maintenance.
c. The blade shape of the seat , can removechlorine stain.
