Water heater safety valves
It is applicable to electric water heater, with both check valve and pressure relief valve functions, it can prevent the water back into the electric water heater and discharge excrescent pressure when the electric water heater inner pressure is at high side, in order to ensure longevity and avoid the blast accident happening. It is a multi-functional storage water type electric water heater safety pressure relief valve, body is three-way, which is divided into inlet chamber, outlet chamber and safety cavity, safety cavity has a drainage hole. Placing check valve core, external regulative spring in the outlet cavity and limited by regulative limit chip, placing flexible gasket, safety valve core and drainage rod, sfaety pressure adjusting spring, the regulative cap is screwed into safety cavity across the drainage rod, with a protect cover outside. At the end of the drainage rod has the drainage ear, it is button up by protect button, and the protect button is fixed on the drainage hole seat by using drainage pipes connector. It has check and reflux, safety pressure relief, drainage cleaning and other functions, and also is convenient to adjust.
specification：1/2″
inlet pressure(opening pressure)：≤0.1MPa
flow: 0.28L/S under 0.03Mpa water pressure
leakage pressure: decompression>0.7mpa stop leakage<0.7mpa
inner release pressure: decompression>0.31mpa stop leakage<0.31mpa
in the state of leaking pressure relief, the water yield is >11 drops every minute.
safety discharge pressure ≤0.7MPa
material: brass
