Description

Mechanical valve

Technical Field

The utility model belongs to the technical field of the valve technique and specifically relates to a mechanical valve that has self-sustaining state of opening or closing that is suitable for use on the filter.

Background

The valve that uses on the filter generally adopts the solenoid valve now, and the solenoid valve generally comprises excitation coil, case, quiet iron core, movable iron core, spring and valve body etc. and its theory of operation is: when the excitation coil is not electrified, the sealing head of the movable iron core closes the valve under the action of the compression spring. When the magnet exciting coil is electrified, the electromagnetic force overcomes the acting force of the compression spring, so that the movable iron core moves towards the static iron core, and the valve is opened. The valve can be kept in an open state only under the condition of power-on, so that the problems of high power consumption and high use cost exist.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problems, the utility model provides a mechanical valve which can keep the open or close state of the valve without electrifying.

The technical scheme of the utility model is that: providing a mechanical valve, which comprises a valve seat with an inlet end and an outlet end, wherein the valve seat is provided with a valve cover, and a diaphragm and a valve core clapboard are sequentially arranged in a cavity formed by the valve seat and the valve cover from bottom to top; a first through hole is formed in the center of the valve cover, an iron core is arranged in the first through hole, an annular groove is formed in the periphery of the first through hole, and a valve core spring and a permanent magnet are arranged in the annular groove; the upper end of the valve cover is provided with a valve core cap and a valve core cover, the center of the valve core cap is provided with a second through hole, and the pressing end of the valve core cover extends out of the second through hole.

As a right improvement of the utility model, in the first through-hole, the upper end of iron core with be equipped with the iron core spring between the case cap.

As an improvement of the utility model, a rubber cap is arranged on the lower end of the iron core.

As an improvement to the present invention, the valve core cap is connected to the upper end of the valve cover by a screw thread.

As an improvement to the present invention, the valve seat and the valve cover are connected by a fastener.

As an improvement to the present invention, the fastener is a threaded rod.

The utility model has the advantages of the valve can be kept in the open or close state without being electrified.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, fig. 1 to 3 disclose a mechanical valve, which includes a valve seat 1 with an inlet end 11 and an outlet end 12, a valve cover 2 is disposed on the valve seat 1, and a diaphragm 14 and a valve core partition 15 are sequentially disposed from bottom to top in a cavity 13 formed by the valve seat 1 and the valve cover 2; a first through hole 22 is formed in the center of the valve cover 2, an iron core 21 is arranged in the first through hole 22, an annular groove 25 is formed in the periphery of the first through hole 22, and a spool spring 23 and a permanent magnet 24 are arranged in the annular groove 25; the upper end of the valve cover 2 is provided with a valve core cap 27 and a valve core cover 26, the center of the valve core cover 26 is provided with a second through hole 261, and a pressing end 271 of the valve core cap 27 extends out of the second through hole 261; in this embodiment, the permanent magnet 24 is an annular permanent magnet with a hole 241 in the center, which is processed by a permanent magnet, and of course, the permanent magnet 24 in this embodiment may also be an annular permanent magnet member in which a plurality of small permanent magnets are embedded on a magnetic conductive ring, so that the cost of the permanent magnet 24 can be reduced.

Preferably, a core spring 28 is disposed between the upper end of the core 21 and the valve core cap 27 in the first through hole 22.

Preferably, a rubber cap 29 is disposed at the lower end of the iron core 21, so that the service life of the iron core 21 can be prolonged.

Preferably, the valve core cap 27 and the upper end of the valve cover 2 are connected by fastening or threads, so that the valve core cap and the valve cover are convenient to disassemble and assemble.

Preferably, the valve seat 1 and the valve cover 2 are connected by a fastener 16. The fastener 16 is a screw rod, which facilitates the disassembly, assembly and maintenance of the two.

When the utility model is used, the valve core cap 27 is pressed downwards to push the permanent magnet 24 to move downwards, the iron core 21 is pulled to move downwards when the permanent magnet 24 moves downwards, and the pressure hole 141 on the diaphragm 14 is blocked by the valve core clapboard 15, so that the valve is closed (see figure 4); when the valve core cap 27 is released, the permanent magnet 24 and the valve core cap 27 are reset by the valve core spring 23, the iron core 21 is sucked back, the valve core clapboard 15 releases the pressure hole 141 on the diaphragm 14, the valve is opened (see figure 3), and the opening or the closing of the valve is realized in a circulating way.

All equivalent changes made by the contents of the specification and the drawings of the utility model are equally covered by the scope of the claims of the utility model without departing from the idea of the utility model.
