The invention relates to a lever-type T-shaped one-way valve, belongs to the field of valves, and can be used for facilities such as floor drains, urinals, hand basins, vegetable washing basins and the like.
Background
At present, a plurality of T-shaped floor drains are on the market, the sealing plates are kept to be in contact with the cylinder body and closed when the floor drain is not discharged through specific acting force, the sealing plates move downwards for a certain distance under the action of water pressure when the floor drain is opened, flowing water flows out from a gap formed between the cylinder body and the sealing plates, and theoretically, about half of drainage capacity of a sewer pipe can be kept on the premise of achieving a deodorization function. However, the arrangement of the force mechanism occupies a large space, and the selection of the force and the acting mode is not good, so that the force applied by the force mechanism is continuously increased in the opening process of the sealing plate, the whole sealing plate is difficult to be completely and effectively opened, the water discharging speed is influenced, and the overflow is easily caused. Meanwhile, the bracket for fixing the force mechanism not only occupies an effective drainage space, but also causes the consequence of hooking sundries such as hair and the like, and finally causes deodorization failure. We propose a lever type T-shaped check valve for this purpose.

Preferably, the connecting rod and the fixed frame are provided with rollers, and the rollers can move smoothly.
Preferably, the lever is provided with a weight at the end far away from the connecting rod by a suspension or gear method, and gravity force is applied to the lever.
Further, the mentioned lever applies force to the position of the lever close to the shaft point through the spring or the spiral spring, so that the lever applies upward acting force to the connecting rod, and the deformation amount of the spring or the spiral spring is smaller when the sealing plate is opened.
Further, the lever is mentioned, and a force is applied to the lever by a magnetic force, so that the lever applies an upward force to the link.
In the present invention, there may be a plurality of the lever structures and the links mentioned.
In the invention, the middle of the sealing plate protrudes towards the inner part of the cylinder body and is in a cone shape.
Preferably, the sealing plate is provided with soft glue at the edge.
Further, the sealing plate is not convex in the middle and is planar.
The invention has the beneficial effects that: firstly, the sealing plate can be opened more thoroughly and discharged more quickly by means of a lever structure and an optimal force application mode; secondly, the force application mechanism can reduce the hooking sundries and avoid the sealing failure; thirdly, the position of the force application mechanism occupies less effective discharge space, and the effective discharge space is large.
