Abstract

A half volumetric-type early-stage rainwater stream abandoning device relates to a rainwater stream abandoning device which aims at solving the problems that the existing rainwater stream abandoning device has oversize volume; after rainfall stops, early-stage rainwater is discharged by manual operation; the device is easily blocked, no rinsing measures are adopted, and impurities are easily deposited, thus going against the normal operation of the device; and the small-volume device has complex structure and high cost. A box is provided with a rainwater shunting room, a rainwater stream abandoning room and a rainwater using room; a rainwater inlet pipe is communicated with the rainwater shunting room; an overflow weir and a splitter plate form a rainwater shunting outlet; a float valve isarranged in a rainwater shunting outlet; a rainwater collecting and utilizing pipe is communicated with the rainwater using room; a normally-closed float bowl valve is arranged in the rainwater stream abandoning room; and a rainwater discharging pipe is communicated with the rainwater stream abandoning room. The device is used for rainwater stream abandoning.

Description

technical field [0001] The invention relates to a rainwater discarding device. Background technique [0002] At present, the volume of most abandonment devices is the volume of all the initial rainwater, resulting in an excessively large volume of the device; although the volume of another device is small, the structure is complicated and the cost is high. Secondly, the waste flow device needs to be manually operated to discharge the initial rainwater after the rainfall stops. Due to the long residence time of the initial rainwater, solid particles and impurities in the initial rainwater are precipitated, and the device is easily blocked. And without flushing measures, impurities are easy to deposit, which is not conducive to the normal use of the device. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the volume of the existing rainwater abandonment device is too large, the initial rainwater is discharged manually aft...
