3. Principle Features
A. Main purpose and scope of application
Automatic free float, free float-type traps can be used for steam heating equipment and condensate recovery system and the need to quickly rule out the condensation of water conditions, so that the steam pipe heating equipment systems and recovery of condensate and remove to gain high heating efficiency, energy conservation a significant effect. Widely used in chemical, oil refining, electric power, textile, pharmaceutical, paper and so on need to condition the steam heating business, especially for low pressure, displacement of large and higher temperature stability, should not lag depositors condensate system is more suitable equipment.
B. Structural characteristics and working principle
a. To a continuous discharge of saturated water and condensate; Water heating equipment will not accumulate to the highest thermal efficiency
b. When the steam pressure is not affected; Float to automatically adjust the water valve seat opening hole, working continuously, stable performance
c. Good sealing performance; This series of products using the float traps all through advanced grinding process, float high precision, good sealing performance
d. Row air performance is good; Automatic free float steam traps automatically exclude condensation of cold and hot gas, effectively preventing the phenomenon of air locks
e. Long life; Float sealing the entire sphere can do all that work is not fixed, concentrated wear
f. Undercooling small to allow high back pressure
g. Condensate Recovery
In condensate recovery system with better results
h. Work Principle; The valves use the principle of buoyancy, float according to the amount of condensation of water changes with water level for lift, automatic adjustment of the valve seat opening hole, a continuous discharge condensate. When the condensed water to stop when the float by gravity down into the bottom, close the drain valve seat hole. Drainage holes in the seat below the water level, water, gas natural separation of the water seal, basically get no steam leakage
4.Operating environment
A. Adapt to any steam condensate discharge pipe on the road and recovery.
B. Air emissions can be used to pressure the water (such as compressor water storage tanks and pipelines to discharge)
C. Automatic free float, free float-type traps with continuous emission of, a formation of condensation water to a certain level on a continuous emissions immediately. Thermal Static starts exclude air evacuation valve to prevent air lock, hot condensate drain valve will be shut down when it reaches the trap valve chamber, the float when the water level by a certain principle of buoyancy to open the main valve system condensate discharge valve seat hole has been, when steam arrived, float down to close the main valve.
Automatic free float, free float steam traps with high load when starting, sealing, waterproofing and anti-vibration hammer characteristics.
5.Proper installation and maintenance
Correct installation, maintenance, security and normal operation is the only guarantee!
A.Check materials, pressure and temperature of the maximum. If the product is less than the maximum operating conditions of the system it installed, you can not install the operation; and ensure that piping systems have safety devices to prevent over pressure.
B.Must be installed before the pressure of gas purge lines, remove dirt, dust, debris and so on.
C.This series of trap doors should be installed in the lower positions, such as steam pipes, valves, filters installed before the cut-off valve; valve should be installed after the check valve, to install the bypass valve and bypass valve.
D.Media flow valve must be installed on the direction of the direction marked on the line, and install a basic level.
E.Valve should be installed at the level of attention to orientation, refers to the horizontal and vertical body itself, does not allow inclined, inverted, etc..
F.After installation or maintenance of the system can guarantee the normal operation of the valve before the need to debug. Alarm or protective devices must be tested.
G.Each installation of heating equipment each trap, so as not to influence each other. Traps as far as possible close to heating equipment installation.
Note: If you want to trap the emissions to the atmosphere to ensure the safety point of emission to the emission of the liquid temperature can reach 100 ℃.
