Abstract
The invention discloses an energy-saving one-freedom turnover discharge valve, wherein, the front of valve has a rubber ring; the front of the rubber ring has a large valve plate; the inner end of large valve plate has a cover plate; the large valve plate has an ventilate holes; the front of ventilate holes have small valve plate connected to the hinge plate; the front right of valve has hinge ear and axial pin; the large valve plate is mounted on the axial pin of hinge ear; the front right hinge ear and the axial pin of valve, the large and small valve plates are upright arranged, and 2-20 degrees leftward inclined, therefore, the invention can use the weights of large and small valve plates as power to reduce the start resistance of small valve plate and realize automatic close.
Description
Technical field
The present invention relates to a kind of drainage and irrigation equipment, especially a kind of type single free side-dump drainage and irrigation valve.
Background technique
Defectives such as at present, what home and abroad irrigation and drainage pumping station valve generally used is rotating hanging formula flap valve valve, and this flap valve valve exists opening angle little, and resistance to water-flow is big, and energy loss is many.Up to the present, it is big not see opening angle on market as yet, and the flowing water resistance is little, can save the valve of a large amount of energy again.
Summary of the invention
It is big to the purpose of this invention is to provide a kind of opening angle, and resistance to water-flow is little, can save the energy-saving type single free side-dump drainage and irrigation valve of a large amount of energy and manpower and materials.
The objective of the invention is to realize in the following way: a kind of energy-saving type single free side-dump drainage and irrigation valve, comprise valve body, rubber ring, big valve plate, cover plate, exhaust port, little valve plate, hinge, hinge ear and pivot pin, front end at valve body is provided with rubber ring, be provided with big valve plate in the rubber ring front, be provided with cover plate in big valve plate the inner, on big valve plate, be provided with exhaust port, be provided with little valve plate at the exhaust port front end, little valve plate is connected with hinge, be provided with hinge ear and pivot pin on valve body front end the right, big valve plate is installed on the pivot pin that cuts with scissors in the ear.
The hinge ear on valve body front end the right and pivot pin and big valve plate and little valve plate are vertically arranged, and are tilted to the left 2～20 °.
The present invention vertically arranges hinge ear, pivot pin and the large and small valve plate on valve body front end the right and is tilted to the left 2～20 ° according to mechanics principle, the deadweight horizontal component that utilizes large and small valve plate reaches opening resistance that reduces valve plate and the purpose of closing automatically as power.
