Flow-limiting valve with single door in different direction

Abstract

The invention discloses a flow-limiting valve with a single door in the different direction. The flow-limiting valve comprises a float bowl, a connecting rod, a single-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. A limiting post is arranged on one side of the valve. The rotating shaft is located above the discharging hole. The float bowl is connected with the rotating shaft through the connecting rod. The rotating shaft is further connected with one end of the single-door water baffle. According to the flow-limiting valve, buoyancy drives the float bowl to move upwards, so that the single-door water baffle is driven to close, and initial rainwater flow limiting is achieved. The flow-limiting 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 flow-limiting valve is worthy of popularization.

Description

Technical field [0001] The invention relates to the field of drainage devices, in particular to a valve that uses a floating ball to drive a water baffle to limit flow. Background technique [0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge facilities in a certain way. The general term for all levels of drainage ditch (pipe) and buildings used to remove waterlogging, prevent waterlogging, and prevent salt. It is mainly composed of field drainage adjustment network, drainage ditches at all levels, waterlogging lakes, drainage gates, drainage pumping stations and drainage capacity areas. In rainy days, the rainwater pipe network needs to limit the initial rainwater with more dirt. Flow requires the use of a restrictor valve, while the previous restrictor valve has the disadvantages of requiring maintenance and requiring external power. Summary of the invention [0003] In view of the above-mentio...
