Abstract
The utility model discloses an overflow valve protection device. A small box is installed at the top inside a sewage case of the overflow valve; the upper part of the small box is communicated with an air suction hose; a water outlet is arranged at the lower part of the small box; a strainer is installed at the joint of the air suction hose and the small box; a floating ball is arranged inside the strainer; and a sewage pipe is connected at the top part of one side of the sewage case. When sewage enters the small box, the floating ball rises gradually, and when the floating ball rises to certain degree, the suction of a draught fan enables the floating ball to block the air suction hose and then the draught fan stops working and an operator is promoted to drain the sewage water. The overflow valve protection device ensures the safe and normal operation of an entire sewage suction system.
Description
Technical field
The utility model relates to the overflow valve protective device on a kind of ground washing vehicle.
Background technology
The sewage disposal process more complicated of ground washing vehicle all is to adopt the form of negative pressure to accomplish basically, scrapes the water rake with the ground sewage scraping, sucks foul water tank by sewage pipe and collects.When foul water tank is collected too much sewage, bigger to the influence of blower fan, cause whole soil pick-up system failure sometimes, cause cisco unity malfunction.
Summary of the invention
The purpose of the utility model is to provide a kind of overflow valve protective device of protecting soil pick-up system, safe handling.
The purpose of the utility model realizes through following technical scheme: the top in the foul water tank of overflow valve protective device is equipped with small box; Small box top is communicated with the air draught flexible pipe; The small box bottom is provided with a delivery port; A screen pack is installed in the junction of air draught flexible pipe and small box, is provided with ball float in the screen pack, and foul water tank one side roof part position connects sewage pipe.
In the time of in sewage gets into small box, ball float slowly rises, and when rising to a certain degree, the suction of blower fan makes ball float block the air draught flexible pipe, and blower fan has stopped work, and the prompting staff emits sewage.Guaranteed whole soil pick-up system, safe operate as normal.
