(54) УСТЮЙСТВО ДЛЯ РЕГУЛИРОВАНИЯ УЮВНЯ ВОДЫ(54) APPROACH TO REGULATING WATER UNION

-I -I

Изобретение относитс к гадфотехнике и может быть использ(жа о на каналах ирригационных систем, в частности дл автоматического регулировани уровн воды в рисовых чеках.,The invention relates to gadphoto technology and can be used on irrigation canals, in particular for automatically adjusting the water level in rice paddies.

1Ьвестно устройство дл регулировани уровн воды, вкшочакхцее вертикальный водсйыпуск, с расположенным в верхнем бьефе мембранным затвором 1 a device for regulating the level of water is known; in the case of a vertical vertical discharge with a membrane valve located in the upstream

Однако это ус ойство обладает недостатспнсй надежностью ввиду возможности заилени иафмембранной полости.However, this device has a lack of reliability due to the possibility of silting up the aphmembrane cavity.

Шиболее близким к предлагаемому вл етс ycipcmciBo дл рег)шировани уровн воды в гидротехнических сооружени х, вклю ча нцее водосбросное отверстие, затвор, выполненный в виде сильфона 12.The most closest to the proposed is ycipcmciBo for regula- tion of the water level in hydraulic structures, including a discharge port, a valve, made in the form of a bellows 12.

Недостаточна надежность этого устройства ари значительной мутности потока обусловлена возможностью заилени полости . . Кроме того, сложность клапанной системы стжает надежность устройства.The reliability of this device is insufficient. . In addition, the complexity of the valve system relieves the reliability of the device.

Цель изобретени - повышение надежности ; устройства при значительной мутности потока и упрощение конструкции.The purpose of the invention is to increase reliability; devices with significant turbidity flow and simplify the design.

Указанна цель достигаетс тем, что в устройстве дл .регулировани уровн воды, содержащее затвор, вьшолненный в виде сильфoнil и размещенный над водосбросным отверстием , дополнительно содержатс подвижна труба, входной патрубок которой закреплен в нижнем торце сильфона горизонтально, This goal is achieved by the fact that the device for adjusting the water level, containing the valve, made in the form of sylphons and placed above the discharge port, additionally contains a movable pipe, the inlet pipe of which is fixed in the bottom end of the bellows horizontally,

10 верхний торец которого, установлен в бьефе неподаижио, причем выходной патрубок , подвижной трубщ размещен в цижнем бьефе на отметке предельного значени уровн , а полость сильфона сообщена с атмосферой 10 the upper end of which is installed in the downstream of the idle, with the outlet nozzle, the movable pipe located in the dungeon at the level limit value, and the bellows cavity is in communication with the atmosphere

15 через патрубок.15 through the pipe.

На чертеже схематически изображено устройство .The drawing schematically shows the device.

Устройство состоит из сильфона 1, прикрепленного верхней плоскостью к раме 2, The device consists of a bellows 1 attached by an upper plane to the frame 2,

Claims

20 rigidly embedded in the inlet tip 3. By means of the outlet of the outlet 4, the upper tail 5 is connected to the lower tail 6. A ring 39 is attached to the lower plane of the bellows 1 39, which, when the bellows 1 is lowered, is supported on the ring seal 8. The cavity of the bellows 1 is connected by means of a nipple 9 communicates with the atmosphere. A hole 10 is formed in the lower plane of the bellows 1, which is throttled by the valve 11. A bracket 12 is attached to the upper plane of the bellows I, on which are mounted the bushings 13 and 14, which have clamping screws 15. In the guide sleeve 13, a rod 16 is fixed, rigidly connected A flexible hose 17, which is connected to the cavity of the bellows 1. In the guide sleeve 14, a rod 13 is installed. An inlet pipe 19 is mounted in the ring 7, a movable pipe 20, the inlet pipe 21 of which is located in the downstream. The inlet 21 is rigidly connected with a vertical stem 22 installed in the guide sleeve 23. The position of the stem 22 is secured using a clamp screw 24. The device operates as follows. During the period when there is no water in the upper and lower pools, bellows 1 is lowered and the spillway 4 is blocked, water is in (sylphone 1 is not, valve 11 pinches port 10. When the upper pool is filled with water under the influence of the bellows 1 acting below, the pressure is the last water is reduced and the water begins to flow through the outlet of water 4 into {shzhi1 bay. The water level in the lower pool psvyshaetsya pzha not flooded outlet nozzle 21. And under the lower plane of the snfon 1 pressure due to its connection with the atmosphere is maintained close to atmospheric. At the same time, the inlet end of the nozzle 17 is located above the water level. When the end of the outlet nozzle 21 is flooded in the area A, isolated from the atmosphere, a vacuum is formed. As a result, the lifting of the bellows 1 stops. The resulting forces acting on the lower plane of the bellows 1, should be directed downwards. The lower plane of the bellows 1 will begin to fall. This will lower the water level in the downstream. As soon as the water level in the downstream drops below the end of the outlet 21, in area A the pressure will increase to The values close to atmospheric pressure. This will lead to a reduction in the strength of background 1 and an increase in the water level in the lower pool. Thus, there will be a stabilization of the water level in the downstream at the corresponding elevation of the outlet nozzle 21 with small upward and downward deviations. The bellows 1 will be periodically reduced and stretched in accordance with the increase and decrease in pressure in the region depending on the end of the outlet pipe 21 relative to the water level in the lower pyre. To stop. The water supply to the lower level must be lowered with the help of the clamp 16 to the flexible pipe 17 under the water level. Bellows 1, filling with water, stretches and overlaps the spillway hole, stopping the flow of water into the lower branch. In order to empty the snfon 1, it is necessary to apply the rod 18 to the valve lever AND, to open the opening 10. The water will drain into the lower reach and the device will be ready for operation. Connecting the cavity below the lower plane of the bellows 1 with a movable tube that functions as a sensitive element, which are usually performed in the form of valves of one or another design, allows to simplify the design without reducing the accuracy of the adjustment. In this case, the bellows is filled with air during leveling, which prevents sediment deposition in the cavity of the bellows and, thus, the device will become more reliable with a significant turbidity of the current. Apparatus of the invention for adjusting the water level, comprising a valve, installed in the form of a bellows and placed above a water outlet opening, characterized in that, in order to increase the reliability of the device, it contains a movable pipe, the inlet of which is fixed horizontally in the lower end of the bellows, the upper end of which installed in the pool motionless, with the outlet of the movable pipe placed in the downstream at the level limit value, and the bellows cavity is in communication with the atmosphere through the pipe.
