A kind of water collecting and distributing device with progressively expanding water inlet pipe and asymmetric arrangement of water inlet and outlet pipes

Abstract

The invention relates to a water collecting and separating device with a divergent water inlet pipe, a water inlet pipe and a water outlet pipe arranged asymmetrically, and belongs to the technical field of water flow collection and distribution devices. The water collecting and separating device comprises the equally straight water inlet pipe, the divergent pipe, a water collecting and separating device tank and the water outlet pipe, and is characterized in that the divergent pipe is arranged between the equally straight water inlet pipe and the water collecting and separating device tank, the divergence angle is 8-16 degrees, the equally straight water inlet pipe is connected with the divergent pipe, the divergent pipe is connected with the water collecting and separating device tank, the diameter of the outlet of the divergent pipe is larger than the diameter of the inlet of the divergent pipe, the diameter of the inlet of the divergent pipe is equal to the diameter of the equally straight water inlet pipe, and the diameter of the outlet of the divergent pipe is smaller than the diameter of the water collecting and separating device tank. The water inlet pipe and the water outlet pipe are connected with the wall of the water collecting and separating device tank in an asymmetrical arrangement mode, are reasonably arranged, and are selected reasonably in the operation process, and energy loss caused by water flow hedging inside the water collecting and separating device tank is avoided. The water collecting and separating device adopts the divergent pipe for water inflowing, the water inlet pipe and the water outlet pipe are arranged asymmetrically and reasonably, vibration of the water collecting and separating device tank and pipelines is reduced to a large extent, water conveying efficiency is improved, and safe, stable and efficient operation of a water conveying device of the water collecting and separating device is guaranteed.

Description

technical field [0001] The invention relates to a water collecting and distributing device, in particular to a water collecting and distributing device which adopts gradually expanding water inlet pipes and asymmetrically arranged water inlet and outlet pipes, belonging to the fields of water supply and heat supply. Background technique [0002] At present, the inlet and outlet pipes of water collectors and distributors used in engineering usually adopt straight pipes with equal diameters. The connection structure between the equal-diameter straight pipe and the intermediate water collector tank is simple, but because the diameter of the water inlet pipe entering the water collector tank is small, the flow velocity and momentum of water entering the water collector tank are relatively large, and the flow section suddenly expands , resulting in a wide range of off-flow vortices, the flow is extremely unstable, the outflow of the water inlet pipe has a severe impact on the wat...

Problems solved by technology

The connection structure between the equal-diameter straight pipe and the intermediate water collector tank is simple, but because the diameter of the water inlet pipe entering the water collector tank is small, the flow velocity and momentum of water entering the water collector tank are relatively large, and the flow section suddenly expands , resulting in a wide range of off-flow vortices, the flow is extremely unstable, the outflow of the water inlet pipe has a severe impact on the water collector tank, and the vortex causes the vibration of the water collector to intensify, the fixed support of the water collector and the water collector tank The pipe itself is easily damaged

When the inlet and outlet pipes of the water collector and distributor are unreasonably arranged, the water flow inside the water collector and distributor tank is prone to hedging, resulting in serious loss of water flow energy
