The operating requirement for steam hydrophobic valves

(1) excluding condensed water vapor does not leak. The exclusion of condensation from time to time, no leakage of steam hydrophobic Carbon Steel PTFE-Lined Valves is the most fundamental condition. Therefore, although it is excluded and the accumulation of steam condensate separation device, but not as condensate traps, and as steam traps. Hydrophobic valve action is accurate, sensitive means of condensate produced opening, closing the case. That exclude condensate, trap open, rapid discharge; discharge end can quickly shut down, prevent leakage of precious steam. This is the trap of the main performance. That is to say, the Cast Iron Valves is fully open and fully closed two cases, if the switch in slow motion, the switch is not in place, will cause the throttling effect, easy to cause the overall damage to the trap, but also the main reason the steam leak.

As on the action principle, Forged Steel Valves is fully open or fully closed, open, close the action. According to the different types, there may be continuous and intermittent discharge of two types of emissions.

(2) can be excluded from any place in the steam system all condensate. Traps must have to condensate produced any part of high-paying, accurately troubleshoot piping, steam use equipment, heat exchangers and other major equipment and steam system.

(3) simultaneous emission of air and condensed water. The air mixed with steam equipment, originally mixed in the steam, the steam into water only to be separated. It is in the heat transfer equipment using steam is formed on the surface of the air layer, seriously affecting the thermal conductivity, so the air must be excluded.

(4) applies pressure range. For the trap, if the pressure has changed slightly the performance to be affected, or even stop the action is not enough, need it in this case the performance is not affected, and can adapt to any pressure. At the same time the trap back pressure to allow a large degree.

(5) easy to repair and maintenance. Structure related to the requirements and the drain valve. Requirements of hydrophobic valve has the advantages of simple structure, fewer moving parts. In order to make the movement of the valve components do not produce stress, should be day to choose suitable materials, more important is its structure should be easy processing. In short, the steam trap management should be no set full-time staff regularly carry out maintenance work, that is to reduce the cost of repair.

(6) high practicality. The trap should be small in volume, light weight, high life, low price, and not because of air or steam barrier and the loss of the drainage capacity, occurrence and air blocking and steam vapor lock and other accidents.
