Abstract
The invention consists of a floating ball and a sealed plastic case. A magnetic control switch is set in the plastic case. On the outer side of the top of the plastic case, there is a sliding way in which there is a plastic slider in which a magnet is sealed, which is made of NdFeB. The one end of plastic slider is connected with the plastic case through an elastic component, and anther end of it is connected with the floating ball through a connective band. There is a wire connected with the magnetic control switch, and is set in sheath. The plastic case is set under the liquid level, and the floating ball drags the plastic slider. When liquid level raises or drops, the floating ball drags the plastic slider to make its position change. At preset position, the slider overcomes the tensile force of elastic component, and changes the position of magnet to make the magnetic control switch act.
Description
Technical field:
The present invention relates to water treatment facilities, relate in particular to the height of water level measuring component, particularly a kind of magnetic control surface cock device.
Background technology:
In the prior art, generally utilize the device of surface cock as sensed water level, be applicable to the occasion of dosing at regular time and quantity, surface cock of the prior art cooperates a lever that connects ball float to constitute by a mechanical switch that seals usually, ball float drives lever, and the lever pushing switch movable contact reaches higher sealing property in order to make electric terminal, surface cock of the prior art often adopts the structure of more complicated, causes use cost too high.
Summary of the invention:
Technical problem of the prior art to be solved by this invention is: because surface cock of the prior art cooperates a lever that connects ball float to constitute by a mechanical switch that seals usually, ball float drives lever, the lever pushing switch movable contact, in order to make electric terminal reach higher sealing property, surface cock of the prior art often adopts the structure of more complicated, causes use cost too high.
The technical scheme that the present invention is adopted for solution above-mentioned technical problem of the prior art provides a kind of magnetic control surface cock device, described this magnetic control surface cock device is made of the plastic shell of a ball float and a sealing, wherein, be provided with a magnetic switch in the described plastic shell, the arranged outside of described plastic shell upper end has a chute, be provided with a plastic cement slide block in the described chute, be sealed with a magnet in the described plastic cement slide block, one end of described plastic cement slide block is fixedlyed connected with described plastic shell by a flexible member, the other end of described plastic cement slide block is connected with described ball float by a connecting band, be connected with lead on the described magnetic switch, described lead is arranged in the sheath, described sheath and the sealing of described plastic shell.
Further, described magnet is made of NdFeB material.
Further, the lower end of described plastic shell is provided with balancing weight.
Further, described flexible member is a spring.
The course of work of the present invention is: plastic shell is positioned over below the liquid level, ball float is by connecting band traction plastic cement slide block, magnet in the plastic cement slide block makes the magnetic switch in the plastic shell be positioned at a normality position, the rising of liquid level or reduction, the position change that causes ball float traction plastic cement slide block, overcome the pulling force of flexible member in the position of setting, change magnet positions, thereby make the magnetic switch action in the plastic shell.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes the magnetic switch of sealing to cooperate the magnet by the ball float traction, can realize the function of surface cock, and simultaneously, described magnet is made of NdFeB material.Can keep reliable magnetic.Hermetically-sealed construction of the present invention is simple, and processing and manufacturing is easy.
