Various types of pneumatic valve steam traps on the market choose pneumatic valve steam traps see details

the hydrophobic pneumatic valve products on the market a lot, but the quality is uneven, the people in the purchase of hydrophobic pneumatic valve products is difficult to buy a good quality hydrophobic pneumatic valve product, when you buy hydrophobic pneumatic valve products, just look for the manufacturer, the manufacturer of hydrophobic pneumatic valve product in general is no problem.
although it is ruled out and steam separation and accumulated water device, but it is not called the condensate drain pneumatic valve, pneumatic valve called steam hydrophobic. Hydrophobic pneumatic valve movement accuracy and sensitivity refers to the condensate have open and shut case. Excluding the condensate, hydrophobic pneumatic valve fully open, rapid emissions; At the end of the discharge and closed quickly and prevent precious steam leakage. This is the main performance of hydrophobic pneumatic valve. That is to say, the hydrophobic pneumatic valve two things only a full open and close, if the switch is slow, switch does not reach the designated position, will cause the throttling effect, overall hydrophobic pneumatic valve damage, at the same time also is the leading cause of leakage of steam. Hydrophobic action principle of pneumatic valve is fully open or close, open and close action. Depending on the type, also may have two types, that is, continuous and intermittent discharge.
according to the actual working condition of using steam hydrophobic pneumatic valve's inlet and outlet pressure differential. Steam drain inlet pressure pneumatic valve refers to because of the fluctuation in the steam pressure or temperature regulating pneumatic valve throttle, pneumatic valve steam traps at the entrance to the minimum working pressure; Steam drain outlet pressure pneumatic valve refers to pneumatic valve steam traps may be formed after the highest work back pressure, when the atmosphere, the actual pressure differential pneumatic valve inlet pressure steam traps. This kind of pneumatic valves shall generally be installed in the pipeline.
in the condensate recovery system, if use work back pressure recovery condensate, should choose high back pressure pneumatic valve steam traps ( Such as mechanical type pneumatic valve steam traps) ； When the requirements shall not be stored up in the condensate steam equipment, continuous discharge should be chosen to saturation of the steam condensate drain pneumatic valve ( Such as ball float steam hydrophobic pneumatic valve) ； In the condensate recovery system, requires both steam equipment to discharge the condensate saturation, asked for a timely exclude condensate gas, should be used to line of saturated water vapor hydrophobic pneumatic valve and exhaust parallel hydrophobic device or use and has function of drainage and exhaust in two kinds of pneumatic valve of steam traps ( Such as hot static type pneumatic valve steam traps) ； When work pressure steam equipment often volatile, should choose don't need to adjust the working pressure of steam drain pneumatic valve.
