Configuration of pneumatic shut-off valve for liquid chlorine cylinder
The pneumatic cut-off valve of liquid chlorine cylinder is also called the pneumatic ball valve of liquid chlorine cylinder. The valve body with pressure lower than PN16 is carbon steel lined with fluorine, and the valve body with pressure higher than PN16 is 316L. According to the production demand on the site, control mode accessories such as explosion-proof solenoid valve, air pressure reducing valve, signal feedback (travel switch), manual device and connecting pipe joint materials are configured. The connection mode includes flange, welding, There are three ways of thread. Actual service temperature of stainless steel shut-off valve: - 40~+150 ℃, application pressure: PN1.6~PN4.0MPa.
There are three control modes for the pneumatic shut-off valve of the liquid chlorine cylinder. The technical department of Shanghai Yonglong Valve Factory will give you a breakdown:
1. Normally closed/single coil control: single acting actuator, working principle: power on and ventilation open, power off and exhaust close, air source fault: valve position closed.
2. Normally open/single coil control: double acting actuator, working principle: power on ventilation closed, power off ventilation open, air source fault: valve position remains in place.
3. Double acting pneumatic cut-off valve/double coil control: one control opening action (power on and air on, coil can be powered off, valve remains open), one control closing action (power on and air off, coil can be powered off, valve remains closed). The normally open/normally closed function can be set according to the site itself. It is the second generation product to replace the normally open shut-off valve. Due to the dual solenoid valve coil control, it effectively prevents the disadvantage that the valve must be opened by ventilation in the state of power-off in case of on-site emergency.
The stainless steel pneumatic cut-off valve for liquid chlorine cylinder adopts CF3M/316L stainless steel silica sol fire proof and anti-static floating ball valve, Daikin PTFE dynamic seal and valve seat seal, 316L solid core ball, which can be applied to liquid chlorine, chlorine, gas, liquid ammonia and medium corrosive media, and connected with the central control system or gas leakage alarm to achieve remote automatic control.
The manufacturers of supporting accessories for the pneumatic cut-off valve include: Yadeke solenoid valve, Renmin Instrument explosion-proof coil, Japan SMC/50-VFE3130-5t-02 solenoid valve, American ASCO/EF8551G401MO explosion-proof solenoid valve, and Renmin Instrument APL-400 signal feedback. Or the user specifies the supporting brand.
