Description

The invention relates to operational ameliorative technology and is intended for flushing closed drainage systems.

A hydraulically operated valve for flushing pipelines, i-chu-chans, is known an operating shut-off organ in the form of a damper rotating on the axis of the valve, provided in the upper part with a plate of ferromagnetic material and a rotation stop in the form of a permanent magnet. An elastic screen is attached to the valve, which forms an open cavity with it, and the valve itself has openings in the upper part for filling the cavity with water. Dl A hydraulically controlled valve for flushing the drainage pipeline is also known, including a shut-off valve with a counterweight attached to the drainage pipe 23 .

Its disadvantage is the complexity of the design and, therefore, low reliability. In addition, for its occurrence, 1 significant difference is required between the drain head and the water level in the receiving water.

The purpose of the invention is to simplify

designs.

 The goal is achieved by the fact that in a hydraulically controlled device for flushing the drainage pipeline which includes an actuating valve with a counterweight hinged at the wellhead section of the drainage pipeline, the stop valve is filled in the form of a rotatable in the vertical plane branch pipe, an extension of the drainage pipeline, and the counterweight is located on the side of the drainage pipeline. pipe and attached to it by means of a rod, the free end of which interacts with the drainage pipe, while counterbalancing the mouth Credited on the rod movable along it in the upper part of the pipeline, is mounted a stop vzaimodeystvun tions with the pipe. .

On the retenge is shown a device for npoMjiBKH drainage piping.

The device for flushing the drainage pipeline Mounts on the wellhead section 1 of the drainage pipeline and includes a test check body in the form of a rotary in the vertical plane nozzle 2 fixed by means of 5 hinge 3 on the drainage pipeline. The hinge is sealed with an elastic annular cuff 4. A rod 5 is attached to the nozzle 2, on which a counterweight 6 is movably mounted, which has been fixed to the rod with a screw 7. The nozzle is turned down by the rod 5 and installed on the pipeline.

s The position of the counterweight 6 on the rod is adjusted and fixed with a screw 7. So that when the level drops to the mark, the corresponding moment to stop the self-flushing of the pipeline, the rotating moment created by the counterweight 6 is balanced by the weight of the wellhead section 1 and the water in it.

The device works as follows.

5 way.

During the period of maximum flow, when the water level in the drainage pipeline Bbmie of the mark corresponding to the termination of self-flushing of the pipe Q, the torque generated by the weight of the wellhead section 1 and the water in it exceeds the rotational moment generated by the counterweight b. At the same time, the wellhead section, resting on the rod 5, is in a horizontal position, and the flow rate of water in the pipeline ensures that the silty part and flakes of ferruginous compounds are carried away with the drainage drain.

When the drainage organ decreases, the water level in the wellhead section of the drainage pipeline decreases, when the level drops below

5 marks, corresponding to the termination of self-flushing of the pipeline, the torque generated by the counterweight 6 exceeds the torque created by the weight of the wellhead section 1 and

there are petals in it, as a result of which the wellhead section on 1 turns back upwards. As it turns, as a result of the flow of water in the drainage section into the drainage pipeline, the rotational moment, which creates the dweeted weight of the flow area 1 with water, rapidly decreases, resulting in a mouth 3

This area occupies a stable position, while resting on support 8.

In position d, the pipelines are gradually filled with drainage drain. When the level rises to the level b, the torque generated by the weight of the wellhead section 1 with water in it exceeds the moment created by the counterweight 6, as a result of which the wellhead section begins to turn down. As it turns, as a result of filling the wellhead area 1 with water, the torque generated by it rapidly increases, as a result of which the wellhead area is occupied

There is a stable position t, resting on the rod 5. At the same time, the flow rate of water in the pipeline provides for the removal of orbital particles and flakes of ferrous compounds with the drainage drain. As the pipeline is emptied, the level in it decreases, reaching the mark

after which the cycle is repeated.

The use of the invention prevents the sedimentation of drainage, eliminates the drainage drainage by draining machines and significantly reduces the cost of its operation.
