Exhaust valve
Exhaust valve is applied to the independent heating system, central heating system, heating boiler furnace, central air conditioning, floor heating, solar heating system pipe exhaust, etc.Because usually have certain air dissolved in water, and air solubility with the rising of temperature decrease, so the water in the process of cycle gas gradually separated from the water, and gradually come together to form a big bubble column, even because there is water, so often have gases.
 
Technical Parameters:
1. Medium: clean water
2. Temperature: normal
3. Body material: gray cast iron
4. Float: 304 stainless steel
5. Test pressure: 1.5MPa
6. Operation pressure: 1.0MPa

When have gas overflow system, the gas will be along the pipeline social climbers, and eventually gathered at the highest point of the system,Exhaust valve (In 19)
And exhaust valve is generally installed in the system, the highest point, when the gas into the vent valve cavity gathered in the upper portion of the exhaust valve, with the increasing of the gas inside the valve, pressure rise, when gas pressure is greater than the system pressure, the gas can make the cavity of the water drops, buoy with water level drops, open the vent;Gas, after the water level rise, buoy also rose, close the vent.Likewise, when negative pressure is formed in system, valve chamber in the water drops, vent open, because the outside atmospheric pressure is greater than the system pressure, so the atmosphere through the vent into the system, avoid the harm of negative pressure.Such as tighten exhaust valve cap on the valve body, stop exhaust exhaust valve, under normal circumstances, the bonnet should be in an open position.Exhaust valve can also be used with isolation valve, easy to the maintenance of exhaust valve.

Mixing Machine

The mixing machine is applicable to mix dry granule material for pharmacy and other relative industries.The machine has the features of the special construction, high effect, no dead angle, uniform mixture. The machine can also increase to blend the function compulsorily. It can mix thin powder and more than two form powders including the materials that contain water. It can get the good result of admixture (meaning that little admixture additives).
