Description
Technical field
The present invention relates to valve field, and in particular to enclosed type safety valve and electric heater.
Background technology
Safety valve is opening and closing element lower in normally off by external force effect, when the pressure medium in equipment or pipeline rises superb
When crossing setting, the particular usage valve of specified value is exceeded by preventing pressure medium in pipeline or equipment to discharge medium outside system
Door.Safety valve belongs to automatic valve class, and control pressure is no more than setting, important protection has been run to personal safety and equipment and has been made
With.
Safety valve common in the market is all using open pressure release mode, such as installed in the peace of electric heater
Full valve, when the hydraulic pressure in inner container of electric water heater reaches setting value, safety valve starts pressure release, by pressure relief opening by the water in inner bag
Discharge, so as to reduce the hydraulic pressure in inner bag.This kind of safety valve can effectively play the effect of protection inner container of electric water heater, but exist
Following problem:
1st, pressure leak process reclaimed water is discharged, and the water of discharge cannot reenter circulation, cause unnecessary waste;
2nd, due to the change that pressure causes in pressure leak process, water is directly contacted with the external world, causes valve body to vibrate in itself, is produced
Utter long and high-pitched sounds (sharp airflow noise);
3rd, when valve inner part occurs abnormal, path is directly produced between electric heater and pressure relief opening, is caused in pipeline
Water ceaselessly discharged, while causing water power to waste, also often there is the water situation of destroying furniture and fixtures of outflow.
