Abstract
Description
Technical Field
[0001] This utility model relates to the field of building drainage technology, and in particular to a buffer drainage device for steel structure workshops. Background Technology
[0002] In the drainage system of steel structure factory buildings, the drainage riser is the core component of drainage. The purpose of the design of the water outlet elbow at the bottom is to change the direction of water flow and avoid water flow directly impacting the ground, causing water splashing.
[0003] However, elbows are usually fixed to drainage risers with clamps. In the case of high-speed drainage or large water flow, the water flow in the drainage riser will form a pressure flow during the drainage process, which increases the impact force of the water flow. The elbow lacks a buffer structure and cannot convert the impact kinetic energy of the water flow into other forms of energy for dissipation. After long-term use, this impact force will cause the elbow to wear, deform or even break.
[0004] Therefore, how to design a buffer drainage device that can reduce the impact damage of water flow to the bend head and extend the service life of the bend head has become an urgent technical problem to be solved in the field of drainage system design for steel structure workshops.

[0025] The technical effects and advantages of this utility model are as follows:
[0026] This invention features a bend at the bottom of the drainage riser.
