And trap antifreeze protection
The proper selection and installation as steam trap, won't appear frozen problem. But if the steam broke, steam condensingwater will be in heat exchanger tube forming vacuum or partners. This will prevent freezing water from the system before discharge freely. Therefore, to being emissions equipment and trap installed a vacuum between damage. If from the trap to the use of emissions, gravity is trap and discharge piping should be used with artificial emissions or the discharge tube anti-freeze measures with automatic emissions. Also, when multiple trap together installed in the trap, to trap heat preservation can prevent freezing.
Anti-freeze measures
1 the trap don't choose dimension.
2 keep trap the discharge line as soon as possible.
3 slopes downward trap discharge pipeline, in order to accelerate the speed of gravity emissions.
4 the trap water pipe the discharge line and condensate with insulation.
5 when exposed to air condensate return piping conditions should be considered when the pipe with partners.
6 if the rise, vertical discharge pipe and tube to ShuiJi upper discharge pipe, and the adjacent discharge pipe and trap heat emission pipe together, see figure 2-42.
Note: the transverse discharge pipe length will cause problems. In pipe distal freezes, hamper the steam trap, never to trap into the water, the valve will freeze.
The steam supply line to elevated and backwater pipeline, allow in outdoor installing ground elevation of the trap. Drain and trap discharge pipe must be freezing heat together. The discharge line should pay attention to the drain valve and check valve and A position. Drain valve and A trap for the cleaning and maintenance supervisor line exhaust steam.
