Lever-type T-shaped check valve

Abstract

The invention discloses a lever-type T-shaped check valve. The lever-type T-shaped check valve comprises a barrel body. An acting force mechanism is installed on the barrel body. A lever structure isarranged inside the acting force mechanism. One end of each lever makes contact with a connecting rod for connecting a sealing plate. By applying downward acting force to the ends, away from the connecting rod, of the levers or applying upward acting force to the ends, close to the connecting rod, of the levers, the ends, close to the connecting rod, of the levers can be kept to be in an upward tendency, the upward acting force is applied to the connecting rod, the connecting rod can drive the sealing plate to form an upward tendency, and the sealing plate and the barrel body can be kept to achieve contact sealing in the non-exhaust state of the check valve. Gravity is preferentially chosen as the acting force of the levers, the acting force onto the sealing plate is kept relatively stable, and opening is made easier.

Description

technical field [0001] The invention relates to a lever-type T-shaped one-way valve, which belongs to the field of valves and can be used in facilities such as floor drains, urinals, wash basins, and vegetable wash basins. Background technique [0002] At present, there are many kinds of T-shaped floor drains on the market. The sealing plate is kept in contact with the cylinder body by a specific force to close when the floor drain is not discharged. When it is opened, the sealing plate moves downward for a certain distance under the action of water pressure. The gap formed between the sealing plates flows out, theoretically, it can maintain about half of the drainage capacity of the sewer pipe under the premise of realizing the anti-odor function. However, because the setting of the force mechanism takes up a lot of space, and the choice of force and mode of action is not good, the force exerted by the force mechanism on the sealing plate continues to increase during the op...

AI Technical Summary

Problems solved by technology

However, because the setting of the force mechanism occupies a large space, and the choice of force and mode of action is not good, the force exerted by the force mechanism during the opening process of the sealing plate continues to increase, making it difficult for the entire sealing plate to be fully and effectively opened, which affects the launching speed , prone to flooding

At the same time, the bracket for fixing the force mechanism not only occupies the effective space for launching water, but also causes the consequences of hooking hair and other sundries, and finally causes deodorant failure
