Description
Technical field
The utility model relates to a kind of sluice pipe bulb types to block dirty structure, belong to hydraulic and hydroelectric engineering metal structure technology neck
Domain.
Background technique
It being needed based on environmental protection, usually sluice pipe will be arranged for ecological flow of releasing in bottom in hydraulic and hydroelectric engineering, and
Sluice pipe is higher general using drain valve operation because of the smaller operating head polishing of port size.Consider sluice pipe bottom suspended load or
Bed load enters runner and is likely to result in valve body damage, and fixed trash rack is generally arranged in its import.It is traditional fixed to block
Dirty grid use welding structure, only lean on because of grid and fix with the weld seam of fence frame contact site, in the tapping pipe that flow velocity is excessively high
It being used in road, grid easily snaps off, and it causes larger dirt to enter sluice pipe damage valve body, is only suitable for the conjunction of flow velocity low field,
So the prior art or incomplete, needs to be further improved.
Utility model content
The purpose of this utility model is to provide a kind of sluice pipe bulb types to block dirty structure, to prevent flowing in stopping leak waterpipe
Speed is excessively high to make grid fracture, and causes larger dirt to enter sluice pipe, valve body is caused to damage, to overcome the prior art not
Foot.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of sluice pipe bulb type of the utility model blocks dirty structure, including sluice pipe；In sluice pipe water inlet
Reduced pipe equipped with prominent dam body facade；Cyclic annular steel plate, cyclic annular steel plate outside are equipped in the junction of dam body facade and reduced pipe
The ribs being uniformly distributed along the circumference is equipped between reduced pipe；The water inlet of reduced pipe is equipped with bulb type dirt barrier hood；Bulb type blocks dirt
Through flanged joint between cover and reduced pipe.
In aforementioned structure, the bulb type dirt barrier hood includes spherical shell section and round tube section, circular arc between spherical shell section and round tube section
Transition connection；The round tube section other end is connect with reduced pipe.
In aforementioned structure, one group of circular hole is evenly equipped in the spherical shell section of the bulb type dirt barrier hood.
In aforementioned structure, the circular hole includes centre bore, remaining circular hole is layered around centre bore and is uniformly distributed along the circumference.
In aforementioned structure, circular hole between layers, which rotates by a certain angle, is staggered into plum blossom-shaped.
In aforementioned structure, round-meshed center line cross at the centre of sphere of spherical shell.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model dirt barrier hood is ring
Shape is uniformly arranged the bulb type shell of circular hole, and shell entirety uniform force is simple to manufacture, and stress caused by welding is concentrated, material
Material relatively saves and dirt is not easy to be attached in dirt barrier hood, is conducive to block dirt；In addition, water flow enters sluice pipe Shi Huixiang by circular hole
Mutually collision energy dissipating advantageously reduces sluice pipe flow velocity, mitigates vibration when dirt barrier hood overcurrent, effectively increases the fortune of drain valve
Row head.
