Commentary on hydrophobic type and working principle of the pneumatic valve products

China pump pneumatic valve business arrangement: in recent years, China hydrophobic pneumatic valve industry into a period of rapid development, has become Asia's largest hydrophobic pneumatic valve processing center, one of the world's largest hydrophobic pneumatic valve market. But our country hydrophobic pneumatic valve products per capita consumption level is not high, in the world is now only $per person. Plant hydrophobic pneumatic valve, pneumatic valve, chemical hydrophobic hydrophobic pneumatic valve construction materials and food with the rise of hydrophobic pneumatic valve etc, show broad prospects, market attractive.

hydrophobic pneumatic valves are used in steam pipe network and devices, can automatically discharge condensate, air and other gases not condensation, and resistance of steam leakage of pneumatic valve.

hydrophobic pneumatic valve type:

depending on the working principle of the pneumatic valve steam traps, steam hydrophobic pneumatic valve can be turned into the following three types:

: mechanical type: rely on pneumatic valve in the condensate steam traps of the height of liquid in who

( Ball float, float as a closed hollow sphere

( Exposure to float upward: float for opening up the bucket

( Exposure to downward float type: float down with the bucket

: hot static type: depending on the liquid temperature change and action

( Bimetallic strip: sensitive original for bimetallic strip

( Steam pressure type: original sensitive for corrugated tube or cartridge, internal filling the volatile liquid

: thermodynamic model: depend on the change of the thermal dynamic properties of the liquid and action.
　　
　　( Disc type: because be in the same pressure, liquid and gas flow velocity is different, the different dynamic, static pressure, pneumatic valve plates driven disc movement

( Impulse type: due to the different temperature of the condensate by polar string orifice plate, sitting between the throttling orifice plate between the different pressure of form, driven by pneumatic disc movement.

hydrophobic pneumatic valve working principle:

. Steam hydrophobic pneumatic valve installed in between the steam heating equipment and water back into the manifold. When driving, barrel at the bottom, pneumatic valve is fully open. Water enter the hydrophobic pneumatic valve flow to the bottom, full of pneumatic valve body, completely submerged barrel, and then, the condensate by pneumatic valve fully open to the manifold.
　　
　　. Steam from the bottom of the barrel into the hydrophobic pneumatic valve, occupy the top of the barrel body, create buoyancy. Barrel rises slowly and gradually to the pneumatic seat direction lever, until completely close the pneumatic valve. Air and carbon dioxide gas vent holes through the barrel, gathered at the top of the hydrophobic pneumatic valve. From vent discharge of steam, due to the hydrophobic pneumatic valve of cooling and condensation.
. When in the condensate began full barrel barrel to leverage to create a pull. As the condensation water level rising, the force of increasing, until can overcome the pressure difference, open the pneumatic valve.
　　
　　. Began to open the pneumatic valve, effect on the pneumatic valve differential pressure will be reduced. Barrel will fell rapidly, make the pneumatic valve is fully open. Accumulate at the top of a hydrophobic pneumatic valve no non-condensable gas discharge first, and then discharge frozen water. When water flowed from barrel drives the dirt out with hydrophobic pneumatic valve. Condensate emissions at the same time, steam again into hydrophobic pneumatic valve, and a new cycle begins.
