Problems solved by technology

[0004] Leakage water, with or without warning, can be collected to a certain extent by the expansion tank, which can be considered a source of recharge, but only as a restrictive or limited source of recharge
If the supply source is depleted and the leak continues, the pressure in the closed liquid circulation circuit will drop rapidly, below a certain pressure, for example, when the pressure in a heating device drops to atmospheric pressure, causing the device Automatic cut-off of operation
For central heating this can lead to disastrous results, for example on a cold night

Embodiment Construction

[0024] figure 1 The drip feeder shown in includes a cylindrical housing 1 with an inlet 2 and an outlet 3. A plunger 4 is slidably provided inside the housing 1, and the plunger 4 includes a first portion 4a, a second portion 4b and a pin-shaped protrusion 4c.

[0025] The first part 4a is internally provided with a cavity 5 for receiving and interposing a filter plate 20 supporting the end of a spring 6 otherwise supported on an annular stop 7 movably arranged in the housing 1 . The outer peripheral surface of the first part 4a moves in a sliding fit along the inner wall of the cylindrical housing 1, while the sealing ring 8 hermetically divides the space in the housing 1 into left and right sides of the first part.

[0026] The diameter of the second part 4b of the plunger 4 is smaller than the diameter of the first part 4a, so that a space 9 is formed inside the housing 1 around the second part 4b. In the outer peripheral surface of the second part 4b is provided a groove...

Abstract

A method for automatically feeding a closed liquid system from a liquid source according to need by creating between the liquid source and the closed liquid system a load buffer formed from liquid, in which between the liquid source and the feed buffer only liquid flow in the direction of the feel buffers is allowed and from the feed buffer to the closed liquid system only drorpwise liquid transport is admitted. The feed buffer can be realized with a cylindrical drip feeder with inlet, outlet and freely movable plunger, which can close the outlet in an abutting position while leaving clear a minuscule leakage channel and is provided with a passage with a non-return valve in the direction of the inlet. Such a drip feeder can, with or without insertion of a storage container for liquid, be connected with, for instance, a liquid system, such as a central heating system with pipe system, boiler and expansion tank.

Description

technical field [0001] The invention relates to a method for automatically feeding a closed liquid system, such as a central heating system or another heat exchange or treatment system designed as a closed liquid circuit, on demand from a liquid source, wherein in the system, The liquid forms the feed buffer and only allows liquid to flow between the liquid source and the feed buffer in the direction of the feed buffer. The invention also relates to a drip conveyor that can be used to carry out the method, and a heating system in which the method and the drip conveyor are used. Background technique [0002] A method as described above is known from WO-A-00 / 19149. A liquid stock is held in a degassing chamber therein, which is replenished as required from a liquid source, more specifically from a public water supply, through a float control valve. In this method, it must be ensured during the feed that no fluid in the closed liquid system can escape under any circumstances,...
