Abstract
The invention discloses a check valve which comprises a valve body and a valve cover arranged on the valve body, wherein the valve body is provided with a water inlet and a water outlet, an upper valve seat and a lower valve seat are arranged on the inner side of the water inlet and connected with a valve plate, a convex groove is formed inside the valve body, and the valve seats are arranged inside the convex groove; the valve plate is in the shape of a Chinese character 'tu', the upper valve seat is in the shape of a Chinese character 'ao', the projected part of the valve plate is connected with the sunk part of the upper valve seat through a bolt, the other end of the valve plate and the lower valve seat are made of magnetic materials. In the check valve disclosed by the invention, soft packing is adopted to seal, so that the sealing effect is better, a concave-convex corresponding shape is adopted between the valve plate and the upper valve seat, so that the valve plate rotates conveniently, the magnetism between the other end of the valve plate and the lower valve seat attracts each other, the magnetic material can be selected according to different application occasions.
Description
Technical field
The present invention relates to a kind of one-way valve, be specifically related to a kind of magnetic single flow valve.
Background technique
Present known one-way valve mostly is the lifting one-way valve, and valve seat and spool adopt rubber seal, and rubber seal is aging easily, the working life of reducing one-way valve.
Summary of the invention
The present invention is directed to the deficiencies in the prior art part, a kind of new one-way valve is provided.
The scheme that the present invention solves the prior art problem is: a kind of one-way valve, comprise valve body, be installed in the valve gap on the valve body, valve body is provided with water intake, water outlet, described water intake installed inside upper valve base, lower valve base, upper and lower valve seat connects valve plate, and a convex groove is arranged in the valve body, and valve seat is installed in the convex groove; Valve plate is convex shape, upper valve base is concave shape, the protrusion place of valve plate and the recess of upper valve base are with bolts, the other end of valve plate and lower valve base adopt magnetic material to make, and the other end of valve plate is opposite with the magnetic of the external port of lower valve base, and the material that the size of magnetic force is selected according to different applications is determined, magnetic material is alloy or rare earth material, adopt soft packing seal between upper and lower valve seat and the valve body, valve gap is convex-down, and adopts soft packing seal between the valve body.
Compared with prior art, adopt soft packing to seal among the present invention, sealing effect is better, adopt concavo-convex corresponding shape between valve plate and the upper valve base, be convenient to the valve plate rotation, the other end of valve plate and lower valve base magnetic between the two attracts each other, and can select magnetic material according to different applications.
