Description

The invention relates to devices for measuring, monitoring, cleaning and stabilizing the pressure for fluid supply systems and, in particular, can be used for water supply in homes, cottages, as well as for other consumers. In addition, this invention can be used in any industry to supply a liquid component.

Known piping systems with flow control valves equipped with connectors for connecting pressure gauges, which are used to calculate the volume flow, and its regulation is carried out by changing the position of the shut-off body (for example, patents DE No. 4030104; EP No. 0671578).

A technical solution is known according to the patent of the Russian Federation No. 2168754, which describes the flow of liquid through a pipeline with a built-in volume flow regulator in the form of a sensing element installed in the flow chamber, and the flow control valve is calibrated, while the measuring device is mounted directly on the sensing element.

The closest analogue of the invention is the technical solution according to German patent DE No. 3432494, in which the actuator (multi-way valve), activator, sensing element and control device are combined into a single unit and in this form is introduced into the pipeline.

The disadvantages of the analogues are the difficulty of mounting and dismounting the measuring and other valves serving the system in the working condition of the entire fluid supply system due to the fact that in the operating mode the system is under pressure (for example, cold or hot water), i.e. in this situation, when removing any device, for example for repair or inspection, drainage of water from the entire system is required.

In addition, when washing pipelines, the above valves and equipment are contaminated.

The objectives of the invention are:

- combine shut-off valves and filtration, pressure stabilization, registration of water (liquid) consumption in one node, thereby minimizing the dimensions of the node;

- provide the ability to replace devices and fittings without dismantling the entire device and without disconnecting the fluid supply system and without presenting requirements for its discharge;

- to protect the measuring elements and regulation from dirt in the operating mode and during preventive maintenance (flushing);

- increase the efficiency of the gravitational collection of filtered particles by providing the ability to rearrange the filter-washing device by 90 ° relative to the axis of the "In-Out" of the device, depending on its location on the pipeline.

The tasks are solved in that a filtering and flushing device is introduced into the measuring, monitoring and cleaning device for the liquid supply systems, comprising a housing, a locking element, a pressure regulator, a liquid meter, and a locking element, a pressure regulator, a liquid meter and a filtering and flushing device made in a single housing, and the locking element is located in the fitting of the fluid inlet, and in the channel between the fluid inlet and outlet fittings there is a pressure regulator detachably connected to the housing; also, using a detachable connection, a filter-flushing device is installed in the housing, which is communicated by the collector with the cavity of the pressure regulator and the cavity after the shut-off element, and a filter is installed at the entrance to the cavity of the pressure regulator; The fluid meter using a detachable connection is also installed in the housing, while the output cavity of the fluid meter is in communication with the fitting of the fluid outlet, and its inlet cavity with the help of another manifold - with the cavity of the pressure regulator.

In addition, the filtering and washing device is rotated 90 ° with respect to the axis of the inlet fitting - the fluid outlet fitting.

Figure 1 shows a diagram of a device in operating mode.

Figure 2 shows a device with plugs (preventive mode).

The device contains:

1 - housing;

2 - locking element;

3 - filtering and washing device;

4 - pressure regulator;

5 - liquid counter;

6 - fitting for fluid inlet;

7 - fitting outlet fluid;

8, 9 - collectors;

10, 11 - holes for installing a filter-washing device and plugs;

12 - threaded pipe for installing a fluid meter or plug;

13 - output cavity of the fluid meter;

14, 15 - stubs;

16 - filter.

The proposed device consists of a housing 1, a locking element 2, such as a ball valve, filtering and flushing device 3, a pressure regulator 4, and a liquid meter 5. The body has a fluid inlet fitting 6 and a fluid outlet fitting 7, manifolds 8, 9. Installation holes filtering-flushing device 10 and plugs 11 in the housing 1, extending into the collector 8, are made in such a way that (depending on the installation of the device - vertical or horizontal relative to the axis of the fluid inlet-outlet fittings), we hold e filter 16, are going to have one of them, located below. A filter-flushing device 3 is installed in this hole (in FIG. 1 in hole 10). The locking element 2 is designed to tightly shut off the input line for the period of replacement of the liquid meter, pressure regulator or filter. The filtering-washing device 3 is designed to filter a liquid, for example water, and to provide periodic washing of the filter 16, made, for example, in the form of a mesh without removing it from the device.

The pressure regulator 4 is designed to maintain a constant pressure after itself when pressure fluctuates at the inlet and to shut off the line in a waste-free mode (in the absence of consumption).

A liquid counter 5 is detachably mounted in the threaded pipe 12, for example, a multi-jet type water meter, with the collector 8 being the counter input and the output cavity 13 being the output.

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

The device operates as follows.

When installing the system in the fluid supply pipeline in the proposed technical solution, plugs 14 and 15 are installed (FIG. 2). Depending on the installation position (vertical or horizontal), a filter-washing device 3 is wrapped (detachable) on one of the holes 10 or 11 respectively, and the other is jammed with a stopper. In this configuration, the system is flushed and crimped, during which dirt is removed from the system without causing contamination of the pressure regulator 4 and liquid meter 5. The dirt is removed through a filter-flush device 3. After flushing, the shut-off element 2 is closed, for example, a ball valve and filter flushing device 3, caps 14 and 15 are turned out, and instead of them, a pressure regulator 4 and a liquid counter 5, for example a water meter, are installed. After opening the locking element 2, for example a ball valve, the device is ready for normal operation.

In this mode, a liquid, such as water, enters with a variable inlet pressure through the shut-off element 2 into the collector 8. The filter 16 prevents the passage of contamination particles and they accumulate under the influence of gravitational forces in the lower part of the manifold 8. The pressure regulator 4 provides output (in the manifold 9 ) pressure, for example, for water systems in the range of 1.2-1.5 kgf / cm ² , this facilitates the working conditions of the moving parts of the liquid meter 5, and this increases its accuracy and reduces the noise on ceramic mixers in the room.

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

Periodically (as a result of clogging), the collector 8 is flushed, for which a hose is put on the filter-flush device 3 and the flush unit tap is opened for some time.

The presence of the locking element 2 allows the replacement of the pressure regulator 4, filter 16, fluid meter 5 without disconnecting the riser of the fluid supply and dismantling the device as a whole. The presence of plugs 14, 15 ensures long-term operation of the device without a counter 5 and (or) a pressure regulator 4, for example, during the re-certification of a meter or repair of a pressure regulator.
