The trap is used for steam pipe network and equipment, can automatic discharge condensate, air and other not condensate gas and steam leakage resistance valve. According to the steam trap working principle is different, the steam trap can be translated into three types: machine type: rely on steam trap condensate fluid guard of the change of the height of action, 1. Steam trap installed in steam heating equipment and water back to ShuiJi between tube. When driving, barrel in the bottom, the valve is fully open. Water into steam trap flow to the bottom of the barrel after, full of the body, all the submerged barrel, and then, the condensate through the full open valve row to back to ShuiJi tube. 2. Steam from the bottom of the barrel and into the trap, occupy the top of the barrel body, to rise. Barrel rising slowly and gradually to seat direction lever, until completely close the valve. Air and carbon dioxide gas through the barrel of the exhaust hole, gathered at the top of the trap. From a vent discharge steam, all would because of the trap heat dissipation and condense. 3. When in the condensate beginning full of barrel of leverage when barrel began to produce a tension. With the setting water level rising, and the resulting growing force, until can overcome the pressure difference, open the valve. 4. The valve begin to open, the function in the disc of pressure difference will be reduced. Barrel will quickly fell, the valve is fully open. Build up in the top of the trap of not being a gas first, and then discharge frozen water. Water flow from the barrel out dirt out driving with the trap. Discharge frozen water at the same time, the steam start again into the trap, new a cycle again.
 
Second: control valves:
 
Control valves is a use of water embellish type from valve body, without the other oil lubrication, such as the case of the Lord in the valve parts damaged, please click the following instructions to remove. (note: in the valve in general consumption damage products for the diaphragm and ○ type circle, other internal parts damage little) 1. The main valve first front end and back end gate valves closed. 2. Will the main valve cap screw loose pipe joints, release the pressure in the valve. 3. Will all screw it, including the necessary control pipe tubes nuts. 4. Take the cover and spring. 5. Will the core, diaphragm, the piston axis and take down, do not damage the diaphragm. 6. Will the above after it out, check the diaphragm and ○ type ring for damage; If no damage to the again points do not dispute the internal parts. 7. Such as the discovery of diaphragm or ○ type circle have damaged, please will axis on the loose screw core, disturbing the diaphragm or type circle decomposition, then take it to replace new diaphragm or ○ type circle. 8. Detailed the main valve internal seating, examine whether there is damage to the core of shaft, if other sundry in the main valve internal will its cleared out. 9. According to reverse the order will change is the combination of the main valve parts pack good, pay attention to the valve can not have jam phenomenon. 10. Please refer to the installation operation caution to use.
