Embodiment Construction
[0014] exist figure 1 Among them, the steel plate is rolled into a lantern-shaped equipment casing 4, and the equipment casing 4 is composed of upper and lower half tank bodies. First, the circumference of the guide element assembly plate 10 is welded to the inner cavity of the upper half of the tank. figure 2 It is a cross-sectional view of the water head limit flow guide element 5, the water head limit flow guide element 5 is inserted into the flow guide element assembly plate 10 with the same aperture evenly distributed, and glued and fixed. The inner cavity of the water head limit guide element housing 15 molded by die casting is put into a sphere 16, and the outer circle of the sphere 16 is evenly matched with the inner wall seat surface of the element housing inlet 17. When the water flow was still, the spheroid 16 fell into the surface end of the funnel-shaped curved seat of the inlet port 17, completely blocked the water from flowing downward, and played the role of ...

The present invention discloses a pipeline fluid multilayer carding anti-aerification device which is assembled at a water inlet of a water conveyance pipeline project and used for orderly carding a fluid through four levels. The fluid at an eddy-flow aerification state is carded and rectified through an antifouling and anti-vortex overflowing plate, an anti-vortex stream guidance pore plate, a rectifying and carding element assembly plate equipped with fluid rectifying and carding elements, and a stream guiding element assembly plate equipped with waterhead limiting and guiding elements; the antifouling and anti-vortex overflowing plate, the anti-vortex stream guidance pore plate, the rectifying and carding element assembly plate and the stream guiding element assembly plate are arranged in parallel inside an inner cavity of the device; a pressure difference between the atmospheric pressure always maintaining a constant pressure and the pipeline which is exposed out of a water surface and always at a vacuum state is then combined, and under pulling of a potential energy generated at a downstream net water head, the fluid is conveyed at a high flowing speed. A laminar flow at a colorless and transparent full-pipe state after carding and rectifying presents a distinct flow state from an eddy flow at a white-foam aerification state in conventional water delivery, resistance generated by gases inside the pipeline is completed removed, frictional head losses of the pipeline are greatly reduced, and a water delivery flow is greatly raised.
Description
technical field [0001] The present invention relates to a kind of pipeline in which part of the water pipeline exposed to the water surface is in a vacuum state, and the other pipelines connected with the equipment of the present invention are in a conventional underwater pressure, and the unique vacuum pressure of 10.336 meters is used Water height, aiming at the vortex turbulent flow aerated fluid at its water inlet, it performs multi-level orderly combing and quickly sends the water pressure to the fluid combing rectification anti-airing equipment in the pipeline under vacuum state. Especially it can be used in water diversion, drainage and water distribution pipeline projects with clean water head. By changing the flow state of the original aerated vortex turbulent fluid into a non-aerated laminar flow state, the gas entering the pipeline with the vortex is completely eliminated, so that the flow level in the pipeline runs smoothly without vortex, the water fullness is inc...
