SYSTEM FOR STABILISING PRESSURE OF AS WELL AS DEGASSING AND MAKING UP WATER IN PIPING SYSTEMS ESPECIALLY DISTRICT HEATING ONES

摘要

1. The system for pressure stabilisation, gas release and water filling is designed especially for heat-supply installations. It consists of a controlling device connected to the membrane tank and the stabilised installation. Unique characteristics: The controlling device (1) is connected to the unpressurised tank (2) and the stabilised installation (3) through two pipes (4) and (5). The latter are connected at the joints (A) and (B) with the pipe (6), equipped with a pressure regulator (7). The pipe (5) of the controlling device (1) is connected to the unpressurised tank (2) through the inlet pipe (11). The section of the pipe between the joint (A) and the stabilised installation (3) is equipped with the solenoid valve (12), the pressure sensor (13) and the flow regulator (14). The pipe (4) of the controlling device (1) is connected to the unpressurised tank (2) through the outlet pipe (17). The section of the pipe between the joint (B) and the unpressurised tank (2) is equipped with the pump (15) and the non-return valve (16). The unpressurised tank (2) is equipped with the gas-release device (18), mounted at the bottom, and the floating membrane (19). The latter consists of the float (20) and the gasket (21), while the float (20) has a profiled recess (22), which collects air. The recess is equipped with the vent valve (23). The unpressurised tank (2) and the stabilised installation (3) are connected directly to the water-filling station (8) through the pipes (9) and (10).
