Problems solved by technology

Generally, the valve disc is set in the vertical fluid pipeline through the self-resetting check valve, which is not suitable for the inclined or horizontal pipeline. The check valve with the valve disc reset by the spring has a wide range of applications, but the elasticity of the spring changes with the The opening and closing times of the valve clack will gradually attenuate, which will affect the control accuracy of the valve body

Embodiment Construction

[0023] In order to further clarify the technical scheme and working principle of the present invention, the invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 1 to Figure 6 A novel one-way valve shown is composed of a housing 1, a plug, and a permanent magnet 6 for controlling the automatic reset of the plug.

[0025] A valve chamber is provided in the housing 1, and a plug is installed in the valve chamber. The housing 1 is preferably made of a non-magnetic material, such as plastic.

[0026] The valve cavity is composed of a main flow channel 3 and an overflow groove 2, such as image 3 , Figure 4 and Figure 6 As shown, the middle part of the main body flow channel 3 is a cylindrical flow channel, and the two ends of the cylindrical flow channel are convex arc-shaped concave grooves. The hemispherical shape with the same flow path diameter makes the longitudinal section of the main...

Abstract

The invention discloses a one-way valve. The one-way valve comprises a shell and a valve cavity arranged in the shell, and is characterized in that a front end face of a main body flow channel of thevalve cavity is provided with a water outlet connected with a water outlet pipe, and a water inlet connected with a water inlet pipe is formed in the rear end surface; a plug is arranged in the main body flow channel, wherein the plug comprises a magnetizer, and the rear end face of the plug is matched with the shape of the rear end face of the main body flow channel; permanent magnets are embedded in the positions, behind the water inlet of the valve cavity, of the interior of the shell; when the water pressure of the water inlet pipe does not exceed a preset value, the plug subjected to magnetic adsorption can automatically fall into a second arc-shaped groove so that the water inlet can be sealed. The one-way valve is novel in structure, reasonable in design, convenient to operate, easyto produce and suitable for pipelines in various installation directions; and compared with a spring type one-way valve, the one-way valve is long in service life, low in maintenance cost and suitable for popularization and use.

Description

technical field [0001] The invention relates to a one-way valve, which is used for fluid control and belongs to the technical field of chemical industry. Background technique [0002] Check valve, also known as check valve or check valve, prevents the reverse flow of fluid through the automatic reset disc. According to the reset principle of the disc, check valve includes spring type, gravity type, etc. Generally, the valve disc is set in the vertical fluid pipeline through the self-resetting check valve, which is not suitable for the inclined or horizontal pipeline. The check valve with the valve disc reset by the spring has a wide range of applications, but the elasticity of the spring changes with the The opening and closing times of the valve clack will gradually attenuate, which will affect the control accuracy of the valve body. Contents of the invention [0003] For the problems existing in the prior art, the technical purpose of the present invention is to provide...
