Abstract

The inventions characterise two variants of a phase-separation storage tank, a coupling non-return drain valve, and a reducing drain coupling. The installation of said elements in a water supply system makes it possible to drain water automatically from an external water supply line and thus prevents the line from freezing during the cold season of the year.

Description

Cumulative phase separation cylinder (options), drain coupling check valve and drain adapter nipple

Description of inventions Cumulative phase-separation cylinder and drain coupling check valve to prevent freezing of the external water supply.

Devices relate to plumbing fixtures for water supply of residential houses, cottages, summer cottages, industrial buildings, structures from wells, wells, other water sources in which the water mirror is below the level of the storage (water folding) capacity.

With the advent of submersible pumps, to drain water from an external water supply, according to the operating instructions, it is enough to make a hole in the pipeline near the submersible pump 1.5-2 mm.

[OS0.446. 126 RE for the vibrating household electric pump Malyatko BV-0.12-40-UB Khmelnitsky 1988]

For a long time, using this method of draining water from an external water supply system laid from a well (through air) through an attic floor to an open drive located in a heated room, despite frosts reaching - 30 degrees, the water supply system worked flawlessly, while observing the slope of the pipeline excluding stagnation of water. After installing an automatic washing machine located in a neighboring building, the washing machine was very slowly filled with water, there was not enough pressure.

To increase the pressure, it is necessary to install a hydraulic accumulator instead of an open accumulator and lay an underground pressure head external pipeline at a depth of 1.5 m along the already landscaped house territory and inside a residential building.

And this:

• dig and build a pit near the well;

· Dig a ditch in the ground 15 m long, 5 m in asphalt;

one

SUBSTITUTE SHEET (RULE 26) • violate 3 m of the floor.

The technical task was to come up with a device that could separate the internal and external water supply systems, preserving the existing one.

This problem is solved by FIG. 1 accumulative phase-separated cylinder, which consists of a sealed enclosure 2 with an automatic air vent 1 mounted in the upper part, working on the exhaust and inlet of air. In the upper cylindrical part of the housing 2 there is an inlet-outlet threaded fitting 3 for connection with the end of the external pressure pipe. At the bottom of the housing there is a threaded fitting 4, to which, through an automatic check valve, an internal accumulator is connected

water folding system.

In the drawing of FIG. 2 shows a collapsible storage

phase-separation cylinder 3, with a nozzle 2 for centrifugal water treatment, a flow filter 4, mounted on a hydraulic accumulator 8.

The disadvantage of draining water from an external pressure pipe through a hole made in the pipeline near the submersible pump is that when the submersible pump is turned on, the pressure of the water in the pipeline is partially reduced; submersible pump performance drops;

water is contaminated from the jet emanating from the hole at high pressure; unnecessary losses of electricity, time and wear of pump parts.

The closest analogue of the invention to drain water from an external water supply by purpose, function and technical result is an automatic drain valve [RU 222271MPK7: P16K17 / 34, B03V7 / 12, VOZVZ / 06, E03V11 12/05/2001; RU N ° 2320827MITJKE03B7 / 12, 03/27/2008].

The disadvantages of the valve are:

• one drain hole;

• the hydraulic resistance of the valve increases with decreasing conditional passage;

• complex design;

SUBSTITUTE SHEET (RULE 26) • lack of forced opening of the valve.

An object of the invention is a new plumbing fixture, including a drain valve: drain coupling check valve, drain adapter nipple, drain nipple, drain adapter and the other.

In the drawing of FIG. 3, a discharge adapter nipple is shown. In the case 1 of the transitional nipple, a metal drain valve 2 is installed, with a seal 3, in the form of a truncated cone, which is fixed to the tension spring 4 and fixed by the extreme turn of the spring 4, in the form of external protrusions, in the annular groove of the housing 1, in which a seat with three through drain holes.

In the drawing of FIG. 4 shows a drain coupling check valve, consisting of a housing 1 ,. drain valve 2, seals 3, springs 4. check valve 5.

Such plumbing fixtures are characterized by:

• simplicity of design;

• forced opening of drain holes after stopping

submersible pump;

• a sufficient number of drain holes for quick draining of water; · Lack of local hydraulic resistance, it

approximately equal to the hydraulic resistance of the water fittings, in which the drain valve is mounted and depends on the conditional passage of the pipeline used.

Installation of a new plumbing fixture will provide:

· Reducing the starting load of the submersible pump electric motor;

• when installing a drain coupling check valve on a screw submersible pump, it will significantly increase the service life of the pump;

• the use of different designs of check valves.

In addition, the installation of a storage phase-separation cylinder and drain water fittings in water supply systems with a closed storage tank (pressure accumulator tank) eliminates freezing

SUBSTITUTE SHEET (RULE 26) external pressure pipe. This makes it possible to lay the external pressure pipe by the air method or at the depth of freezing of the soil, which allows:

• provide the necessary minimum supply of cool, fresh, purified drinking water;

• refuse to build expensive pits and caissons;

• completely eliminates or minimizes earth robots under

• engineering Communication;

• bring water supply to existing dwellings without destroying

improvement of adjacent territories and buildings at any time of the year;

• lay water supply through attic floors from top to bottom;

• simplifies installation, maintenance, disassembly, replacement of pipelines and fittings at any time of the year.

In water supply systems with open drives, to protect the external pressure pipe from freezing, it is enough to use one drain water fittings.

A storage phase-separation cylinder is installed vertically in a heated room.

Drainage water fittings are installed on the external pressure pipe below the level of soil freezing.

Work devices.

When you turn on the submersible pump 8 (Figure 5) opens the check valve 5 (Figure 4) drain coupling check valve. Under the action of a high-pressure head, water, overcoming the force of the spring 4, presses the drain valve 2 of the drain coupling check valve with a seal 3, to the seat of the housing 1 preventing it from flowing out. Moving along the external pressure pipe 2 (Figure 5), the water displaces the air located above the mirror of the water source to the accumulative phase-separated cylinder (further NFB) 3.

At the same time as the pump 8 is turned on and the pressure in the NFB 3 increases, the automatic air vent 1 releases air located in the pipeline 2 and the NFBZ. When the air pressure in the NFBZ becomes large from the pressure of the water in the accumulator 10, the internal water system, the check valve 5 opens and the water from the NFBZ enters the accumulator 10. At the same time, the air is displaced by the water from the NFBZ through the air vent 1 and the water closes it. Filling with water

hydraulic accumulator 10 to the required pressure, the pressure switch 9 activates and turns off the submersible pump 8. Under pressure from the water in the system, the check valve 5 (Figure 4) closes. The water pressure in the entire system, external and internal, is equalized. Under the action of the spring 4 (Figure 4), the drain holes of the drain valve 2 open and water begins to drain from the outer pipe 2 (Figure 5) into the water source. The check valve 5 closes, separating the accumulator 10 from the NWF 3 and the outer pipe 2. Water merging through the drain holes of the drain valve 2 (Fig. 4),

SUBSTITUTE SHEET (RULE 26) drain coupling check valve 7 (Figure 5) reduces the pressure in the NFB 3 to atmospheric. The air vent 1 operates on the air inlet to the NFB 3 and water, under the action of hydrostatic pressure in the outer pipe 2, flows from the NFB 3 to the level of the inlet-outlet fitting 3 (Fig. 1), and the outer pipe 2 (Fig. 5) to the level of the mirror source of water.

If necessary, a bypass assembly can be installed in the well or well, at a depth of non-freezing, consisting of a drain

water fittings and a remote-controlled three-way tap, which will allow you to use the water supply system in winter-summer mode. To do this, it is necessary to release air from the storage phase-separation cylinder and close it in the process of filling the accumulator with water.
