Abstract

The utility model relates to a magnetic-control valve comprising an upper and a lower valve bodies, a valve core which is threaded in the neck of the upper valve body and is capable of moving up and down, and a valve plate arranged in the valve core. A rotary handle is arranged above the valve core; a position corresponding to the valve core on the rotary handle is embedded with a permanent magnet. An inner cavity of the valve body is divided into an upper and a lower cavities through the valve blade; the side wall of the lower valve body is provided with a water inlet communicated with the inner cavity of the valve body, and the lower valve body is provided with a water outlet. The valve blade is provided with the water inlet through which the upper and the lower cavities are communicated, and is also provided with a decompression hole corresponding to the valve core and the water outlet on the lower valve body.

Description

A kind of magnetic control valve

The utility model relates to a kind of valve, especially a kind of magnetic control valve

At present, common magnetic control valve is electromagnetism control valve on the market, generally be to coil in valve block upper half, utilize electromagnetic principle to open valve block after connecting power supply, and then open the fluid passage, though this kind mode has reached the switch purpose, but consume certain electric power, and when water flowing, must remain energising, otherwise will be owing to gravity and elastic force effect, valve is closed.Power consumption greatly also is the common fault of this class valve.

A kind of advanced method-promptly finish the break-make of water by moving up and down magnet is now also arranged at present, but much more difficult on than tangent direction, also big many of consumed energy at moving magnet on the Normal direction.

A kind of simple in structure, the reasonable idea that the purpose of this utility model designs at existing problem in the above-mentioned prior art just, and have the energy-saving effect magnetic control valve.

The purpose of this utility model is achieved by the following technical solution:

Magnetic control valve of the present utility model comprises upper and lower valve body, is installed in the upper valve body neck and spool movable up and down, is arranged in the valve block of valve pocket, is provided with a swing handle above spool, is installed with permanent magnet at swing handle and the corresponding position of spool; Body cavity is divided into two chambeies up and down by valve block, offer the water intake that communicates with body cavity at following body wall, following valve body is provided with water outlet, on the valve block except that offering the water inlet that is communicated with two chambeies up and down, also be processed with a relief hole on valve block, described relief hole is corresponding with the water outlet position on spool and the following valve body.

Compared with prior art, maximum characteristics of the present utility model are: be to rely on the magnetic force of permanent magnet to keep and consumed power not in the 1. water flowing process, so also saved electric energy greatly; 2. simple and reasonable, to use easy to maintenancely, the cost cost is low.

Accompanying drawing is a structural front view of the present utility model.

The utility model is done below in conjunction with accompanying drawing and is described in further detail:

As shown in the figure, this valve comprises upper and lower valve body (6) (9), be installed in the upper valve body neck and spool movable up and down (5) and spring (4), be arranged in the valve block (7) of valve pocket, be provided with a swing handle (2) in the top of spool (5), be installed with permanent magnet (3) in swing handle (2) and the corresponding position of spool (5), described swing handle (2) is hinged with bearing pin (1); Body cavity is divided into two chambeies (14) (13) up and down by valve block (7), offer the water intake (8) that communicates with body cavity at following body wall, following valve body is provided with water outlet (10), valve block (7) is gone up the water inlet (12) in two chambeies about offering connection, on valve block, also be processed with a relief hole (11), described relief hole (11)) corresponding with the position of water outlet (10) on spool (5) and the following valve body (9).

Working principle of the present utility model is: the swing handle band permanent magnet and can be rotated around bearing pin, when permanent magnet rotates away from spool (5), spool can be in spring (4), drop under the synergy of gravity and negative pressure on the valve block (7), relief hole (11) on the valve block is stopped up, and water enters in the uuper valve chamber (14) by the water inlet (12) on water intake (8) and the valve block, valve block this moment (7) is close to valve body (9) upper water-out mouth top down under the compressing of hydraulic pressure, two cavity pressure balances about making, current are static, when need are opened valve, only permanent magnet need be threaded to directly over the spool, spool is under the sucking action of magnet, overcome gravity and spring force and leave valve block, at this moment the water that is positioned at the valve block upper chamber will spray from relief hole (11), make the rapid pressure release of upper cavity, when upper cavity pressure was lower than lower chamber pressure, valve block will leave down airtight of valve body top, and the current that make flow out naturally from water outlet (10).

Claims

1, a kind of magnetic control valve, it comprises upper and lower valve body (6) (9), be installed in the upper valve body neck and spool movable up and down (5), be arranged in the valve block (7) of valve pocket, it is characterized in that: be provided with a swing handle (2) in the top of spool (5), be installed with permanent magnet (3) in swing handle (2) and the corresponding position of spool (5); Body cavity is divided into two chambeies (13) (14) up and down by valve block (7), offer the water intake (8) that communicates with body cavity at following body wall, following valve body is provided with water outlet (10), valve block (7) is gone up the water inlet (12) in two chambeies about offering connection, also be processed with a relief hole (11) on valve block, described relief hole (11) is corresponding with water outlet (10) position on spool (5) and the following valve body (9).
