In this hole (figure 1 into the hole 10 is set filtering and washing device 3. The locking element 2 is designed for leak overlap the input line for the period change of the counter fluid pressure regulator or filter. Filtering and washing device 3 is designed for filtering liquids, such as water, and ensure periodic cleaning of the filter 16, made for example in the form of a mesh without removing it from the device.

The pressure regulator the s 4 is designed to maintain a constant pressure behind fluctuations in the inlet pressure and for closing the highway in betrachten mode (in the absence of consumption).

In a threaded socket 12 Rethimno metered liquid 5, such as water meters multi-jet type, and the collector 8 is a counter input and output cavity 13 - exit.

In addition, the device is equipped with plugs 14 and 15 (figure 2), which can hermetically be installed instead of the counter liquid 5 and the pressure regulator 4 in the mode of prevention or control mode of the meter and/or regulator.

When the unit is installed in the supply line of fluid in the proposed technical solution, installed the plugs 14 and 15 (figure 2). Depending on the position of the mounting (vertical or horizontal) in one of the holes 10 or 11 respectively wrapped on the threads (Rethimno) filtering and washing device 3, and the other off tube. In this configuration, is held flush and pressure test the system, which removes the dirt from the system without causing contamination of the pressure regulator 4 and the counter liquid 5. Dirt is removed through filtering and washing device 3. After washing the closed shut-off element 2, for example ball valve and filtering and washing device 3, clear of the sides of the plugs 14 and 15, and instead set the pressure regulator 4 and the counter liquid 5, such as water meters. After opening the shut-off element 2, e.g. the ball valve, the device is ready for normal operation.

In this mode, the liquid, for example water, is supplied with a variable input pressure through the closing element 2 in the reservoir 8. The filter 16 prevents the passage of contaminants and they are under the influence of gravitational forces accumulate in the bottom of the reservoir 8. The pressure regulator 4 provides the output (collector 9) pressure, for example, for water systems in the range of 1.2 to 1.5 kgf/cm²it facilitates the work of moving parts counter liquid 5, and this increases the accuracy and reduces noise on ceramic faucets in the room.

In the absence of consumption of the pressure regulator 4 blocks water flow and maintains a constant pressure Bezruchenko mode and thus reduces leakage through valves that saves water up to 10-20%.

Periodically (as clogging) is flushing manifold 8, which on filtering and washing device 3 is put on the hose and at some time, opens the faucet drilling site.

The presence of the locking element 2 allows replacing the pressure regulator 4, the filter 16, the counter liquid 5 without disconnecting the riser inlet fluid and dismantling of the device as a whole. The presence of the plugs 14, 15 provides long-term operation of the device without counter 5 and(or) pressure regulator 4, for example, on the time the recertification counter or repair pressure regulator.
