Abstract

Exhaust Hydro Shock Impulse Device (VSU IU) belongs to the field of public utilities and is intended for pipe cleaning. Cleaning, flushing pipes and punching plugs is carried out by short-term hydraulic shock, the source of which is air exhaust. Exhaust Hydro-Impact Pulse Device is a mechanism consisting of a pneumatic cylinder with a piston and two rods. The piston, inside of which the inner tubular rod extends, presses the shut-off valve with a spring through the outer tubular rod, the opposite end of which "sits" in the holder of the supporting cylindrical part. The spring, supporting cylindrical part and the part of automatic opening of the shut-off valve are closed by a metal protective cap that is attached to the back air cylinder cover. A handle with a trigger is attached to the protective cap to manually open the shut-off valve. The shut-off valve is attached to the inner stem with a pin through the washer and nut. The hairpin passes in the pipe of the inner rod and exits the back cover of the protective cap. From inside the spring, the part for automatically opening the shutoff valve is screwed onto the hairpin. The piston, under the influence of forced air, moves away from the shut-off valve and, through the outer rod and the support part at the end of the rod, pushes the part to automatically open the shut-off valve with a pin, an inner rod and a shut-off valve, thereby opening the exhaust opening. An exhaust is made. To manually open the shutoff valve, the pin is connected to the trigger. Air is pumped into the pneumatic cylinder from the compressor through a channel and a coupling located on the side surface of the front cover of the pneumatic cylinder. The set of VSU IU includes rubber conical plugs with a bore in the middle and serve to block the pipe opening sewage during pneumohydroshock.

Description

1. Field of technology.

Exhaust hydropercussion impulse device (VSU IU) refers to the field of public utilities, namely:

A) it is used to clean the inside of the house and inside the quarter sewer pipes from blockages, dirt, debris, sludge and other household wastewater, to punch plugs and eliminate obstruction in the sewer pipes;

B) is used to flush and clean the piping heating and heat supply systems from dirt and sludge;

B) can be used to raise water to the height of buildings and structures located above the secured pressure from the source of water supply;

2. The prior art.

The closest analogue to an exhaust hydropercussion impulse device is a kinetic hydraulic ram (KGT).

Kinetic hydraulic ram is patented in the USA. U.S. Patent No. 1998902 C. B08B 9/00, 1967

When developing an exhaust hydropercussion impulse device, the task was set:

1. To create an analogue of KGT with improved technical characteristics;

2. Increase the speed of the air exhaust, and thereby increase the strength of the shock pulse;

3. Develop a device that produces air exhausts in automatic mode.

This problem is solved in an exhaust hydroblow impulse device containing a pneumatic cylinder with covers, a shut-off valve, a piston and two tubular rods - an internal and an external one, one end of the external rod is fixed to the piston, a supporting cylindrical part is connected to the other end of the external rod, through which the external rod and the piston is pressed against the shut-off valve by a spring, the shut-off valve is attached with a pin to the inner rod, the inner rod is located in the center of the piston and inside the outer rod, from the outer end of the inner rod, n heels, leaving the inner rod fixed piece automatic opening of the isolation valve.

In addition, the exhaust hydropercussion impulse device further comprises a tee with a check valve and a pressure gauge for pumping air and controlling the pressure in the pneumatic cylinder.

In addition, the exhaust hydropercussion impulse device further comprises a protective cap fixed to the rear cover of the pneumatic cylinder and the cover of the protective cap, which is made in the form of a twisting figure and serves as a stop for the spring.

In addition, the hydropercussive impulse pulse device additionally contains a handle with a trigger fixed to the cover of the protective cap, and the trigger is connected via a cable to a pin coming out of the cap of the protective cap. The hydropercussive impulse device performs the function of an air exhaust source and is an independent mechanism, device, device for cleaning pipes, and can also be used in industries that use air exhaust.

Exhaust hydropercussion impulse device can be used in all methods, methods and in installations for flushing, cleaning sewer pipes, piping heating and water supply systems, in which air exhaust is used as a source of hydroblow.

3. Disclosure of the essence of the utility model.

Exhaust hydropercussion impulse device is designed on the well-known principle of short-term hydraulic shock to a column of water in the pipe, followed by transmission of the shock to blockage. The strength of the impact depends on the speed of the exhaust air and on the amount (weight) of water in the pipe. Water is elastic, relatively incompressible fluid and the transmission of shock to blockage in the pipe occurs almost instantly.

The force of the shock wave is transmitted along the pipe, and very little effect on the side surfaces of the pipe. Bends and turns of pipes do not interfere with the propagation of a shock wave of water.

The force of the impact can be adjusted and set depending on the contamination and type of cleaning.

BUT). The problem of blockages and plugs in sewer pipes at considerable distances from revisions and cleaners is successfully solved with the help of a hydraulic shock caused by air exhaust from the Voronezh State University.

B) When flushing the heating system, the speed of water increases with the speed of air exhaust from the exhaust impulse impulse device, thereby creating a bubbling in the water, washing away the layers of dirt and sludge from the inner walls of the heating pipes and radiators.

Unlike KGT, in an exhaust hydroblow impulse device the speed of air exhaust is much faster, thereby increasing the force of water impact on the blockage. This is due to the fact that in the Voronezh State University, the air exhaust occurs not only due to the differential pressure, but also due to the expulsion of the piston by a rigid spring, as well as due to the increased area of the exhaust opening. In the exhaust hydroblock impulse device manual and automatic opening of the shutoff valve is provided.

In a kinetic hydraulic ram, air exhaust occurs only due to the excess pressure of the air pumped into the tank. The shut-off valve in KGT is opened only manually.

3.1. Description of the essence of the utility model.

Exhaust hydroblow impulse device is an exhaust source for the formation of water hammer.

The exhaust hydropercussion impulse device is made in the form of a pneumatic cylinder (pos. 1, Fig. 1) with a piston and a through rod, the piston is supported by a spring, the spring is closed by a protective cap to which a handle with a trigger is fixed. From the center of the front cover (pos. 3, Fig. 1) of the pneumatic cylinder, a flare (pos. 5) with an external thread of% inch and an internal hole with a nominal diameter of 20 mm, which serves as an exhaust opening, comes out. A flange is provided on the opposite side of the thread in the drive. The flange is pressed through the rubber gasket to the inside of the cover of the pneumatic cylinder and tightened with a lock nut on the outside of the cover.

From inside the pneumatic cylinder, the air exhaust port is closed by a rubber shut-off valve (key 6). A rubber shutoff valve is secured to the front end of the inner stem (key 7) through the washer with a pin (key 9) and a nut. The stud extends inside the stem. The inner stem is made in the form of a metal pipe and is coated with chrome on the outside. The piston (pos. 2) is made with a hole in the center through which the internal stem passes. The piston moves along the inner rod. The piston is made of aluminum.

Air is exhausted by removing the inner stem with a pin and a shutoff valve back, opening the exhaust opening. The piston, at the moment of opening the shut-off valve, under the influence of the air pumped into the pneumatic cylinder, compressing the spring, is moved away from the shut-off valve.

The air pressure in the pneumatic cylinder acts not only on the piston, but also on the shut-off valve, preventing the piston from dragging the internal stem behind it and opening the shut-off valve. A metal washer is installed between the rubber shutoff valve and the inner stem. The surface area of the washer (excluding the cross-sectional area of the inner rod) was calculated from the condition of “not extruding the shut-off valve” by water located on the outside of the drive at the moment the piston leaves the shut-off valve.

To calculate the area of the washer, the water pressure from the outside of the shut-off valve is assumed to be 6.0 kg / cm ² . The force compressing the spring, which presses on the piston and, accordingly, on the shut-off valve (without pumping air), is adopted 20 kgf (0.196 kN). An external stem is attached to the rear of the piston (key 8). The external stem is made in the form of a metal pipe and chrome plated on the outside. The external stem exits the rear cover (key 4) of the pneumatic cylinder. The outer end of the outer rod is pressed and “sits” in the holder of the supporting cylindrical part (pos. 10). The supporting cylindrical part is made of metal in the form of two short cylinders (cages) of different diameters lying on the same axis with a partition between them and a hole in the center of the partition (for passage of the inner rod). A spring (pos. 12) on the opposite side of the partition wall of the supporting cylindrical part “sits” also in the cage (in the cylinder) and presses the external rod and piston.

The other end of the spring is supported by the cover of the protective cap (key 14) and is also located in the cylindrical cage of the cover of the protective cap. The inner rod leaves the outer rod, passes through the hole of the supporting cylindrical part to the middle of the spring.

A stud comes out of the inner rod and passes through an opening in the cover of the protective cap. The pin for automatically opening the shut-off valve (key 11) is screwed onto a stud located inside the spring, which exits through the opening of the cover of the protective cap with its outer end. The inner end of the automatic opening of the shut-off valve is made in the form of a cylindrical cup and serves as a stop. Under the action of compressed air, the piston, through the outer rod and the supporting cylindrical part, shifts the part to automatically open the shut-off valve, the stud with the inner rod and shut-off valve, thereby opening the exhaust opening.

A nut is welded to the outer end of the automatic valve opening part, which is made in the form of a coupling (key 15). Adjustment of the moment of opening the shut-off valve and the degree of compression of the spring is carried out by tightening-unscrewing the nut. The spring is located in the protective cap (key 13). The protective cap is made in the form of a metal pipe, closed on both sides by covers with holes, and connected to the rear cover of the pneumatic cylinder. A thread is provided on the inside of the protective cap on the back cover side. The back cover of the protective cap is twisted-untwisted by thread, thereby increasing / decreasing the initial compression ratio of the spring.

To manually open the shutoff valve, a trigger with a trigger (key 16) is attached to the protective cap. The trigger is pivotally connected to the handle, and the pin is connected to the trigger through a cable (key 17). When pulling the trigger, a pin with an internal stem and a shut-off valve is pulled out through the cable, and an exhaust opening opens. For air injection, a channel and a coupling are located on the side surface of the front cover of the pneumatic cylinder. A pressure gauge (key 19) and a non-return valve are screwed into the coupling through a tee (key 18). The pressurized pressure is from 1 to 12 atm depending on the need.

The set of VSU IU includes rubber conical plugs with a hole in the middle with a diameter of 26 mm. Plugs are used to block sewer pipes during pneumatic shock. A sweep is inserted into the plug hole, tightened on both sides with locknuts, and connected to the Exhaust Hydro-Impact Pulse Device via a quick-release coupling.

4. A brief description of the drawings.

4.1. In FIG. 1 shows the internal structure of an air shock impulse device with a specification of parts;

4.2. In FIG. 2 shows a method of cleaning sewer pipes using a VSU IU when the pipe is completely filled with water; in FIG. 3 shows a method of washing and cleaning sewer pipes when the pipe is not completely filled with sewage, FIG. 4 shows a method of cleaning the pipes of a domestic sewage system in a well, (a description of the implementation of work is given in Section 5 of Section A.);

4.3. In FIG. 5 shows the method of cleaning and flushing the heating system using the VSU IU, (the description of the work is given in section 5, paragraph B);

4.4. In FIG. 6 schematically shows the method of water supply technology to consumers in high-rise buildings and structures with insufficient water pressure in the water supply system without the installation of pressure boosting pumps. The volume of injected air into the air shock impulse device is very small and with a small water consumption it is possible to use a very small compressor, up to a car compressor, to pump air, which of course will be more economical than installing a pressure boosting pump and pressure regulators

5. Implementation of a utility model.

BUT). The result of the kinetic energy of the air exhaust is punching plugs in the pipelines of the sewage system, as well as the preventive and operational cleaning of the sewer, water and heating pipes from dirt, sludge and mechanical suspensions.

To eliminate the non-throughput capacity of the pipes as a result of the formation of plugs in them, in the sewer pipelines of the openings of the cleaners or revisions, a rubber conical plug is inserted and pressed in with a bend in the middle. An exhaust hydropercussion impulse device is connected via a quick disconnect clutch to the end of the plug. If the sewage from the pipe comes close to the plug (an important condition is that there are no air plugs between the plug and the water), then the compressor is connected and the VSU IS is filled with air. Under the pressure of the injected air, the piston in the exhaust hydroblock pulse device compresses the spring. The air pressure readings at the Voronezh State University are monitored by a manometer. Pressing the rubber cone plug more tightly to the sewer pipe, a shot is fired by pulling the trigger. (Fig. 2).

In the event that the wastewater leaves the pipe a little through a blockage, then additionally tap water is connected through the tee and the pipe is filled with water.

After filling the sewer pipe with water, and VSU IU air, a shot is fired. (Fig. 3; Fig. 4).

For the purpose of preventive, operational cleaning of the sewer pipe, the hole at the opposite end of the pipe is closed with a plug and a pneumohydraulic exhaust is produced in a similar way.

B) Every year, after the end of the heating period, pipelines of heating networks and heating systems are hydropneumatically flushed and cleaned of dirt, sludge, silt and grease. Flushing and cleaning of pipes, risers and radiators is carried out with tap water and a uniform flow of air from the compressor. Hydro-pneumatic flushing with a water-air mixture uniformly flowing into the pipes does not provide high-quality flushing of the heating pipes and heating appliances.

The use of an exhaust hydropercussion impulse device for washing and cleaning heating pipes, risers and radiators will significantly affect the quality of cleaning the internal surfaces of pipes and radiators, since the air exhaust into the pipes will be pulsed with acceleration and at the same time create turbulences of water and sparge in the pipes and heating devices .

Flushing the heating system using an exhaust hydropercussion impulse device is carried out according to the following procedure: (Fig. 5)

1. Plugs are installed between the flanges of the valves at the input to the building of heating networks;

2. An exhaust hydroblow impulse device is connected through a tee to the supply pipe of the heating system;

3. The water supply is connected to the tee, and the compressor is connected to the VSU IU through the hose;

4. The heating system of the building through the water supply system is filled with water;

5. A hose is connected to the return pipe of the heating system and discharged into the sewer network;

6. The discharge valve opens and at the same time the water supply and compressor are turned on to pump air into the Voronezh State University. Exhaust hydropercussion impulse device operates in automatic mode.

AT). In urban areas, along with 5-9-storey buildings, there are high-rise buildings. To provide water for residents of these high-rise buildings, high-pressure pumps with high electric power are installed at water sources, or high-pressure pumps, which also consume a lot of electricity, are installed in high-rise buildings, pressure regulators are installed on risers and inlets of water pipes in the apartments (so that the pressure does not exceed the set pressure standards).

To provide water to residents of floors for which water "does not reach" due to a lack of pressure at the source of water supply, it is possible to apply water supply technology to these floors using a water hammer (Fig. 6).
