Pipe networks for various purposes are, as a rule, equipped with filters that allow you to get rid of unwanted impurities (mechanical, chemical, biological) included in the working environment. Their use makes it possible to obtain a clean product, which ultimately leads to the safety of all kinds of equipment and extends its service life.
During operation, such devices can leak, which will subsequently lead to costly consequences. To avoid this, in modern networks of water supply, heating, supply of all kinds of technical liquids, a specially designed filter with protection against leaks is used, which can be either a main filter or a large-sized filtration column.
Types of leak prevention systems
Depending on the principle of operation, metal products can be autonomous or with control sensors. Each option has its own specific advantages.
Filters with mechanical protection
The demand for such pipeline equipment is justified by a number of advantages, among which are:
- non-energy independent ;
- simplicity of design;
- low maintenance.
These metal products react to changes in pressure. If it decreases (which may indicate a leak), the valve closes and the substance does not enter the part of the pipeline with the suspected leak. As a rule, such elements in filtration plants are used as auxiliary ones. This is due to the fact that they are unable to operate in case of minor leakage of connections or minor damage to pipes. The design of the system consists of a coupling in which a spring valve is installed. It is mounted on the supply pipe line.
Products equipped with sensors
Such devices are the most reliable and can prevent even a small leak of the working medium. They include several fundamental components:
- control unit (controller);
- automated faucet;
- leak detection devices.

The principle of operation is based on the fact that almost any liquid is capable of conducting electric current. During operation, when a malfunction occurs, water enters the electrode of the product, resulting in the circuit being closed. The electric pulse is supplied to the controller, which in turn ensures that the locking mechanism is closed via an electric drive.
Factors influencing performance indicators
Filters with leakage protection are actively used in technological systems of various enterprises, from utilities to heat and power complex. To maximize the efficiency of devices, a number of criteria should be taken into account. First of all, this is the maximum permissible pressure in the pipeline. The installation option (flange, coupling, welded) is also taken into account. If an electronic system is used, then it is necessary to pay attention to the sensitivity and type of connection to the power system.
