Hot water tank and pressure device

摘要

The water tank (1) has a tank (4) for storing hot water, and an inlet (6) for supplying cold water to the tank. An outlet (8) discharges the hot water from the tank, and a pressure device (2) is arranged between the inlet and the tank for automatically controlling the inlet during reaching of adjusted value of a tank-sided system pressure. The device is connected with a pressure relief pipeline (20), and has a piston (12) that is loaded with the system pressure in a closing position. The piston separates a spring area (26) from a pressure area, and spring-loaded in an opening position. An independent claim is also included for a pressure device for a hot water tank.
