Abstract
The utility model relates to a magnetic control liquid level switch which is composed of a cylindrical sealed pipe body which is arranged vertically. At least two magnetic reed switches are fixedly arranged in the cylindrical sealed pipe body along the axial line of the pipe body. Any one magnetic reed switch is connected with a conducting wire which passes through the upper end of the sealed pipe body. The outer side of the sealed pipe body is sheathed with a circular ring member, and an annular sealed cavity is arranged in the circular ring member. A permanent magnet is arranged in the annular sealed cavity. The upper end and the lower end of the sealed pipe body are respectively provided with a fixedly connecting bracket. The sealed pipe body is vertically arranged in the liquid, and the hollow circular ring member floats on the liquid surface. When the liquid surface changes, the vertical position of the circular ring member changes subsequently and the permanent magnet in the circular ring member is switched with the magnetic reed switch on the positioned height. When the liquid surface is higher or lower than the set detection position, the utility model can continue to reflect the change of the liquid surface by that the hollow circular ring member changes the height along with the change of the liquid surface, and thus, the magnetic reed switches which are continuously arranged on the vertical height can be triggered.
Description
Technical field:
The utility model relates to water treatment facilities, relates in particular to the height of water level measuring component, particularly a kind of magnetic controlled liquid level switch.
Background technology:
In the prior art, generally utilize the device of liquid-level switch as sensed water level, liquid-level switch 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, but a liquid-level switch can only detect a liquid level, when liquid level continues to surpass or is lower than the detection position of setting, just can not reflect that the continuation of liquid level changes.
Summary of the invention:
The purpose of this utility model provides a kind of magnetic controlled liquid level switch, and described this magnetic controlled liquid level switch will solve the technical problem that liquid-level switch in the prior art can only detect unique liquid level.
This magnetic controlled liquid level switch of the present utility model is made of a vertically disposed cylindric sealed tube body, wherein, axis along body in the described cylindric sealed tube body is set with two magnetic reed switchs at least, any one described magnetic reed switch all is connected with lead, described lead passes the upper end of sealed tube body, the outside of described sealed tube body is arranged with an annulus member, be provided with an annular closed cavity in the described annulus member, be provided with permanent magnet in the described annular closed cavity.
Further, described permanent magnet is circular.
Further, the two ends up and down of described sealed tube body are respectively arranged with fixedly connected support.
The course of work of the present utility model is: sealed tube body is vertically set in the liquid, the connection support and the liquid container at two ends are fixed up and down to utilize sealed tube body, hollow annulus member floats on the liquid level, when liquid level changes, variation is followed in the upright position of annulus member, and the permanent magnet in the annulus member is connected the magnetic reed switch on the height of place.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model utilizes hollow annulus member to follow level change to change height, thereby triggers the magnetic reed switch that is provided with continuously on vertical height, can continue the reflection liquid level variation when liquid level surpasses or is lower than the detection position of setting.
Description of drawings:
Fig. 1 is the structural representation of magnetic controlled liquid level switch of the present utility model.
Embodiment:
As shown in Figure 1, magnetic controlled liquid level switch of the present utility model is made of a vertically disposed cylindric sealed tube body 1, wherein, axis along body in the described cylindric sealed tube body 1 is set with two magnetic reed switchs 2 at least, any one described magnetic reed switch 2 all is connected with lead, described lead passes the upper end of sealed tube body 1, the outside of described sealed tube body 1 is arranged with an annulus member 3, be provided with an annular closed cavity in the described annulus member 3, be provided with permanent magnet 4 in the described annular closed cavity.
Further, described permanent magnet 4 is circular.
Further, the two ends up and down of described sealed tube body 1 are respectively arranged with fixedly connected support 5.
