В напорной обшивке 6 напротив отверстий 13 напорных трубопроводов 8 выполнена перфорация 14. Низовая обшивка 7 ниже ригеля 5 выполнена перфорированной.The proposed shutter contains made in the form of rectangular trapezoid. upper 1 and lower 2 vertical diaphragms facing one another with larger: mi bases 3 and 4, between which _; the bolt 5 is rigidly connected to them. The lock contains a pressure sheathing 6 and a bottom sheathing 7, pressure pipes _{15 of} water 8 with shutoff valves 9. Tubing; melt flow energy dampers 10 are located between every two adjacent ones; lower vertical diaphragms 2.: Each pressure pipe 8 is installed perpendicular to the pressure casing 6 and 20 is connected by one end 11 to the pressure casing 6, and the other end 12 to a tubular flow damper 10, the axis of which is located in a vertical plane parallel to the bottom casing 7. B perforated sheathing 6 opposite the openings 13 of pressure pipelines 8 is perforated 14. The bottom sheathing 7 below the crossbar 5 is perforated.

Затвор снабжен дополнительным перфорированным ригелем 15, жестко закреп- ₃₀ленным к нижним вертикальным диафрагмам 2 в нижней их части 16.The shutter is equipped with an additional perforated crossbar 15, rigidly fixed ₃₀ to the lower vertical diaphragms 2 in their lower part 16.

Мусороподъемник 17 расположен на напорной обшивке 6 перед перфорацией 14. Запорная арматура 9 напорных трубопроводов 8 соединена с приводом 18, а мусоро- 35 съемники 17 с приводом 19. Водовод 20 имеет напорный 21 и низовой 22 участки.The garbage truck 17 is located on the pressure casing 6 before the perforation 14. The shut-off valve 9 of the pressure pipelines 8 is connected to the drive 18, and the garbage collectors 35 are pulled 17 with the drive 19. The water conduit 20 has a pressure head 21 and a bottom 22 sections.

Плоский глубинный затвор водовода работает следующим образом.Flat deep shutter conduit operates as follows.

Перед подъемом затвора посредством привода 18 запорная арматура 9 открыва- ⁴0 ется, и вода поступает через напорные трубопроводы 8 в трубчатые гасители 10 энерЬидЬ гии потока, а из них — в пространство, между нижними вертикальными диафрагмами 2 и далее через перфорированную низовую обшивку 7 ниже ригеля 5 в низовой участок 22 водовода 20, создавая низкоскоростной защитный поток.Before the shutter is lifted by the actuator 18, the shut-off valve 9 is opened ⁴ 0, and water enters through the pressure pipelines 8 into the tubular dampers 10 of the flow energy, and from them into the space, between the lower vertical diaphragms 2 and further through the perforated bottom casing 7 below crossbar 5 in the lower section 22 of the conduit 20, creating a low-speed protective flow.

Затем затвор поднимается, при этом транзитный поток вступает во взаимодействие с низкоскоростным защитным потоком, что улучшает условия работы затвора за счет снижения кавитации.Then the shutter rises, while the transit stream interacts with the low-speed protective stream, which improves the operating conditions of the shutter by reducing cavitation.

Claims

The invention relates to hydraulic engineering and can be used to block deep water lines. The purpose of the invention is to increase reliability by reducing cavitation. FIG. 1 shows a flat deep-water seal of a conduit, a vertical section; in fig. 2 is a view A of FIG. 1. The proposed shutter contains the upper 1 and lower 2 vertical diaphragms, made in the form of rectangular trapeziums, facing one another with large bases 3 and 4, between which the bolt can be fixed, the bolt 5 rigidly connected to them 5. The shutter contains the pressure cover 6 and the bottom cover 7 , pressure pipelines 8 with shut-off valves 9. Pipe: flow dampers 10 of the flow energy are located between each two adjacent: lower vertical diaphragms 2.: Each pressure pipe 8 is installed: perpendicular to pressure cover 6 and connected it has end 11 with pressure plating b, and the other end 12 with a tubular absorber 10 of energy flow, the axis of which is located in a vertical plane parallel to the lower plating 7. In the pressure plating 6 opposite to the holes 13 of the pressure pipe 8, a perforation 14 is made. Bottom trim 7 below the crossbar 5 is perforated. The shutter is provided with an additional perforated bolt 15 rigidly fixed to the lower vertical diaphragms 2 in the lower part of them 16. The garbage elevator 17 is located on the pressure shell 6 before perforation 14. The shut-off fittings 9 of the pressure pipelines 8 are connected to the drive 18, and the dust collectors 17 are driven 19. The drain 20 has a pressure head 21 and a downstream 22 plots. Flat deep gate conduit works as follows. Prior to raising the shutter by means of the actuator 18, the shut-off valves 9 open and water flows through the pressure pipelines 8 into the tubular flow energizers 10, and from them into the space between the lower vertical diaphragms 2 and then through the perforated bottom casing 7 below the crossbar 5 into the downstream section 22 of the conduit 20, creating a low-speed protective flow. The shutter is then raised, whereby the transit flow interacts with the low-speed protective flow, which improves the working conditions of the shutter by reducing cavitation. Claim 1.
