Lever type automatic closing valve

Abstract

The invention discloses a lever type automatic closing valve. Two valve door plates comprise arcs-shaped panels and fan-shaped side plates at two sides; a discharging opening formed in the lower end of a hopper is just sealed by the arc-shaped panels of the two valve door plates; the fan-shaped side plates at two sides are fixedly arranged at two sides of the arc-shaped panels; the upper end of each fan-shaped side plate is hinged to the outer side of the discharging opening of the hopper; the inner side of a hinging shaft of the two valve door plates is provided with mutually engaged gears; one end of a rope is connected with one valve door plate; the other end of the rope is connected with the end part of one end of a first lever; the end part of the other end of the first lever is hinged to a substrate; a connecting rod is in vertical arrangement; the upper end of the connecting rod is hinged onto the first lever; the lower end of the connecting rod is hinged to the end part of oneend of a second lever; the second lever is hinged to the substrate. The lever type automatic closing valve has the advantages that the valve can be opened in a labor-saving way; the effective controlof loading is realized; the labor is used in the whole process; the external connection of a power supply is not needed; safety and convenience are realized; the wharf loading and unloading efficiencyis improved.

Description

technical field [0001] The invention relates to an automatic closing valve, in particular to a lever type automatic closing valve. Background technique [0002] Bulk materials on the wharf are transported to the storage hopper by the ship unloader after being unloaded by the ship unloader for pre-storage, and then need to be transported to the warehouse by loading trucks or directly transported away, so the loading efficiency directly affects the overall wharf unloading efficiency. When the loading truck is reloading, the valve at the lower end of the hopper is opened to load the material onto the truck. The traditional loading valve at the lower end of the hopper adopts an electric or manual push-pull method. When the push-pull operation is performed, due to the heavy weight of the material, Therefore, the work intensity is very high, time-consuming and labor-intensive, and the electric valve needs an external power supply, so there will be a power line, and the trucks on ...

When the loading truck is reloading, the valve at the lower end of the hopper is opened to load the material onto the truck. The traditional loading valve at the lower end of the hopper adopts an electric or manual push-pull method. When the push-pull operation is performed, due to the heavy weight of the material, Therefore, the work intensity is very high, time-consuming and labor-intensive, and the electric valve needs an external power supply, so there will be a power line, and the trucks on the wharf come and go, the situation is complicated, and the power line is extremely dangerous
