ELECTRIC WATER HEATER WITH SHUT-OFF VALVE FOR WATER FILLINGPROBLEM TO BE SOLVED: To provide an electric water heater which calls user's attention to danger filling high temperature hot water in a bath tub.;SOLUTION: This electric water heater is equipped with: a shut-off valve opening and ...
Check valves are important in a water heater because they prevent flooding or overflowing. They also stop the water from constantly flowing backwards, even when the heater is off. This prevents eroding of the pipes and saves power. Operation of a Check Valve There are several types of check v...
The utility model relates to an electric water heated provided with an electric proportion valve and including a cistern, an electric heater, a water intake pipe, a hot water pipe,a cistern temperature sensor, a controller and a distant operator, wherein, the electric heater heats the water ...
When the electrical hook up is complete, check that the water heater’s drain valve is closed and if not, close it. Next, fill the appliance with water by opening the valve that supplies the appliance.Do not restore power to the water heater until the appliance is completely filled with ...

热继电器的主要参数有热继电器额定电流、相数,热元件额定电流,整定电流及调节范围等。热继电器的额定电流是指热继电器中可以安装的热元件的最大整定电流值。热元件的额定电流是指热元件的最大整定电流值。热继电器的整定电流是指热元件能够长期通过而不致引起热继电器动作的最大电流值。通常热继电器的整定电流是按...
答:熔断器在电气线路中主要起短路保护和严重过载保护作用,而热继电器主要用于过载保护.两者不能互为代用,但可以互为补充.如果用熔断器作电动机的过载保护,为了防止电动机在启动过程中熔断器熔断,熔断器熔体的额定电流一般应取电动机额定电流的2.5~3倍,这样即使电动机长时间过负荷50%,熔断器也不会熔断,而电动机可能因...
