It is mainly composed of field drainage regulation network, drainage ditches at all levels, waterlogging lakes, drainage sluices, pumping and drainage pumping stations, and drainage capacity and discharge areas. In rainy days, the rainwater pipe network needs to intercept the initial rainwater with a lot of dirt , it is necessary to use a shut-off valve, but the previous shut-off valve has the disadvantages of maintenance and external power.

Abstract

The invention discloses a shutoff valve with double doors in the same direction. The shutoff valve comprises float bowls, connecting rods, a double-door water baffle, a gate, a box body, a rotating shaft and a rubber sealing ring. The gate is fixed to one side of the box body. A discharging hole is formed in the middle of the gate. The rubber sealing ring is arranged around the discharging hole. The rotating shaft is located above the discharging hole. The float bowls and the double-door water baffle are hinged to the rotating shaft. According to the shutoff valve, buoyancy drives the float bowls to move upwards, so that the double-door water baffle is driven to be closed, and initial rainwater closure is achieved; the shutoff valve can be used in municipal water conservancy systems for initial rainwater collection and storm sewage pipeline backflow preventing; no external power and manual maintenance are needed, and the shutoff valve is worthy of popularization.

Description

technical field [0001] The invention relates to the field of drainage devices, in particular to a valve which uses a floating ball to drive a water baffle to realize flow interception. Background technique [0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge and other facilities in a certain way. The general term for all levels of drainage ditches (pipes) and buildings used for waterlogging, waterlogging, and salt prevention. It is mainly composed of field drainage regulation network, drainage ditches at all levels, waterlogging lakes, drainage sluices, pumping and drainage pumping stations, and drainage capacity and discharge areas. In rainy days, the rainwater pipe network needs to intercept the initial rainwater with a lot of dirt , It is necessary to use a shut-off valve, but the previous shut-off valve has the disadvantages of needing maintenance and external power.
