Description

Magnetic one-way valve

Technical Field

The utility model relates to the technical field of valves, concretely relates to magnetic force check valve.

Background

The check valve is liquid, the necessary valve of gaseous relevant equipment one kind, prevent that the inside fluid of pipeline from producing the adverse current because pressure changes, when some liquid, gas contains strong corrosivity, when strong oxidizing property, require to increase the valve body, especially the inside spring that provides the case reset of valve body works in the stress alternation for a long time, the great scene of relative deformation, among the prior art, traditional check valve mostly all promotes through the spring and realizes reseing, and if the spring is at the inside fracture of valve body, then can lead to the valve inefficacy, thereby cause the accident.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical scheme that technical problem adopted is: magnetic force check valve, including the valve body shell, the inside of valve body shell can be dismantled and is connected with the disk seat, the top fixedly connected with of disk seat goes up the valve bonnet, the bottom fixedly connected with rubidium magnet of going up the valve bonnet, the below swing joint of rubidium magnet has the case.

As a preferred technical scheme of the utility model, the inner wall threaded connection of disk seat and valve body shell, be equipped with the sealing washer between disk seat and the valve body shell.

As a preferred technical scheme of the utility model, the top fixedly connected with rubidium magnet of case No. two, one side that No. two rubidium magnets and a rubidium magnet are close to each other is with the magnetic pole.

As a preferred technical scheme of the utility model, the outside of a rubidium magnet and No. two rubidium magnets is wrapped up by polytetrafluoroethylene entirely.

The utility model has the advantages of it is following: the invention provides a one-way valve scheme without a spring, which realizes the closing of the valve by the repulsion of two rubidium magnets and the pressure of fluid in the valve, cancels a reset mechanism such as a spring and the like, and reduces accidents such as valve body failure and the like caused by the failure of the spring.

fig. 2 is a schematic structural diagram of the valve closure of the present invention.

Description of reference numerals: 1. the valve comprises a valve body shell, 2, a first rubidium magnet, 3, a second rubidium magnet, 4, an upper valve cover, 5, a valve core, 6, a valve seat, 7 and a sealing ring.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention will be further explained with reference to the accompanying drawings.

Please refer to fig. 1-2 in combination, the magnetic check valve of the present invention comprises a valve body housing 1, a valve seat 6 is detachably connected inside the valve body housing 1, an upper valve cover 4 is fixedly connected to the top of the valve seat 6, a first rubidium magnet 2 is fixedly connected to the bottom of the upper valve cover 4, and a valve core 5 is movably connected to the lower portion of the first rubidium magnet 2.

Disk seat 6 and valve body shell 1's inner wall threaded connection, the convenience is dismantled disk seat 6, be equipped with sealing washer 7 between disk seat 6 and the valve body shell 1, improve the sealing capacity between disk seat and the valve body shell 1, no. two rubidium magnet 3 of top fixedly connected with of case 5, one side that No. two rubidium magnet 3 and No. one rubidium magnet 2 are close to each other is homopolar, can repel each other through the principle that the homopolar repulsion of magnet keeps away from, no. one rubidium magnet 2 wraps up by the polytetrafluoroethylene is complete with No. two outside of rubidium magnet 3, prevent that rubidium magnet from being corroded by inside fluid.

Specifically, the utility model discloses during the use, go up valve bonnet 4 department low pressure relatively when 6 below liquid of disk seat or gaseous relatively, go up valve bonnet 4 department liquid or gaseous relatively disk seat 6 department high pressure, case 5 and disk seat 6 contact, no. two rubidium magnet 3 of case 5 afterbody keep away from rubidium magnet 2 of last valve bonnet 4 department this moment, the valves is closed, when last valve bonnet 4 department liquid or gaseous by high-voltage change low pressure, when 6 liquid of disk seat or gaseous relatively go up valve bonnet 4 high pressure, pressure is greater than the repulsion force between two rubidium magnets, jack-up

case

5, 6 department high pressure of disk seat promotes case 5 and removes, make No. two rubidium magnet 3 be close to rubidium magnet 2, kinetic energy turns into elastic potential energy storage, when 6 departments of disk seat and last valve bonnet 4 department high-low switching of relative pressure, elastic potential energy release converts kinetic energy into, promote valve core 5 and disk seat 6 contact, thereby close the valves.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
