Manual operation, pneumatic or electric trap model for the STR, high-temperature steam trap is a maze-type and cascade-type high-pressure differential regulating valve, the valve suitable for thermal power plant main steam and reheat steam pipe drainage systems, control saturated water pressure drop, high temperature steam trap can be pneumatic or electric control, manual steam trap model for the MTR. It is a large thermal power unit one of the key valve. The main advantages of high-temperature steam traps: A control fluid velocity 30m / S is about preventing cavitation damage, labyrinth fluid passage, fluid changing direction; permissible pressure 25MPa. 2, saving face and sealing surface separately, noted in the drainage flow with different throttle components, valve components of surface hardening, the hardness can reach HRC70, closed tight, long life. 3, valve body components of the structure with self-sealing internal pressure, the greater the pressure, sealing the better. 4, body components and implementing agencies with floating connection, you can remove the spool and putting the card in different cardiac death caused by the phenomenon.
