Leak protector for sealed circulation system

Abstract

A leakage protector for use in a sealed circulation system includes water inlet and return pipes for connecting the circulation system. In the water inlet pipe are disposed a water intake valve, a mass flow meter and a temperature probe and in the water return pipe are disposed a water return valve, a mass flow meter and a temperature probe. The mass flow meter and the temperature probe collect processing units by a wire connection signal. The water return pipe is in communication with the discharge pipeline via a three-way connecting piece and a draw-off valve is set at the water outlet.

Description

technical field

[0001] The invention relates to a water leakage / air leakage protector equipped with a sensing element and a central processing unit, more specifically, a water leakage / air leakage protection device used in a sealed circulation system. The present invention is mainly used in a system in which heat supply (cold) is realized by a single-component gas (liquid) body or a sealed cycle of gas (liquid) body with a fixed ratio. Background technique

[0002] At present, there are few sealed circulation systems with water leakage protection devices. When leaking occurs in the plumbing system of ordinary households, the generally adopted measures are to artificially close the plumbing valves of the households. The problem is that when there is no one at home, because the valve cannot be closed in time, the leaking part of the pipeline will continue to leak, which will not only waste the hot water resources in heating, but also affect the heating of nearby residents.
