Abstract
The utility model discloses a vertical float ball level switch comprising a swing mechanism, a relocation mechanism and two switch contacts, wherein a swing rod in the swing mechanism is arranged upright, and the middle of the axial direction of the swing rod is connected with a hinge of a supporting base. The supporting base is fixed on a main body, a pressure spring is arranged between the lower end of the swing rod and the supporting base, and both ends of the spring are respectively connected with the swing rod and the main body. The relocation mechanism is formed by that after fixedly connected by a floating ball and a floating rod, the relocation mechanism is vertically arranged in a conduit. The utmost upper end of the floating rod is provided with an iron core, and two switch contacts are arranged on a perpendicular between the swing mechanism and the relocation mechanism. The top position and the bottom position of each switch contact are level with both ends of the top and bottom of the swing rod. The utility model is attracted by a permanent magnet and the iron core to push the switch contacts to close and output liquid level signals, the closing is quick and reliable, is not influenced by the fluctuation of liquid, and thus, the utility model is especially suitable to be as a liquid level switch for a high position container.
Description
Technical field
The utility model relates to a kind of appliance switch, and specifically, the utility model relates to a kind of appliance switch of monitoring liquid level.
Background technology
Liquid-level switch is a kind of appliance switch that the liquid level in the container is monitored of being used for, the liquid-level switch of prior art is distinguished from structure and is mainly contained mechanical type and electronic type two big classes, its common structure characteristics are to be provided with switch contact at the liquid level setting position, variation control contact by liquid level is opened or is closed, in time, output device body fluid position signal objectively.But the switch contact of prior art liquid-level switch stability when closure is subject to the liquid fluctuation influence and produces rub-out signal output inadequately, causes unnecessary loss.
The utility model content
The utility model is at the deficiencies in the prior art, provides a kind of and is provided with structurally that magnet steel is inhaled mutually with iron core and the vertical floating-ball level switch that helps the switch contact closure.
Vertical floating-ball level switch contains swing mechanism, relocation mechanism and switch contact; Fork in the described swing mechanism is placed vertically, and it axially is connected with bearing hinge at the middle part, and bearing is fixed on the body, is provided with spring in the lower end of fork between the bearing, and both ends of the spring is connected with body with fork respectively; Described relocation mechanism also vertically places conduit to constitute after being fixedlyed connected with floating lever by ball float, and floating lever moves up and down along conduit with ball float; Described switch contact places between swing mechanism and the relocation mechanism on the vertical line, and the position of switch contact flushes at two ends up and down with fork respectively; Its difference is: described fork is provided with magnet steel respectively in both ends up and down; Described floating lever the top portion is provided with iron core.
In the said structure, any magnet steel that is provided with when two ends on iron core that floating lever topmost is provided with and the fork near the time nature all takes place inhales mutually, fork is that the center swing is the pull switch closing of contact with the hinge of bearing.The magnetic force of magnet steel keeps the normally opened contact steady closure.
The utility model compared with prior art, switch contact is inhaled mutually by magnet steel and iron core and is promoted closed and remain closed, closed rapidly, reliable, and the not influence of liquid body fluctuation.
Description of drawings
Fig. 1 is the structure principle chart of the vertical floating-ball level switch of the utility model when minimum liquid level;
The structure principle chart that Fig. 2 is the vertical floating-ball level switch of the utility model when the highest liquid level.
Embodiment
Vertical floating-ball level switch contains swing mechanism, relocation mechanism and switch contact.Fork 2 in the described swing mechanism is placed vertically, it axially is connected with bearing 3 hinges at the middle part, and bearing 3 is fixed on the body 12, and fork 2 upper and lower sides are respectively equipped with magnet steel 1 and 4, to being provided with a compression spring 9 between the bearing 3, spring 9 two ends are connected with body 12 with fork 2 respectively in the lower end of fork 2.Described relocation mechanism also vertically places conduit 7 to constitute after being fixedlyed connected with floating lever 6 by ball float 5, and the upper end of floating lever 6 is provided with iron core 8.Described switch contact 10 and 11 places between swing mechanism and the relocation mechanism on the vertical line, and switch contact 10 and 11 position and the fork magnet steel that both ends are provided with respectively about in the of 21 and 4 flush.When liquid level during in extreme lower position, promptly ball float 5 is in position shown in Figure 1, and the iron core 8 of floating lever upper end is the shortest with the magnet steel of fork 2 lower ends 4 distances, and magnetic force overcomes spring force and attracts fork 2 swings and pull switch contact 11 closures, the low liquid level signal of output.When liquid level rises, ball float 5 come-ups promote floating lever 6 and move up along conduit 7, position shown in Figure 2 when the top of floating lever 6 arrives the setting liquid level, iron core 8 is inhaled and pull switch contact 10 closures mutually with the magnet steel 1 of fork 2 upper ends, and the signal of liquid level is set in output.Simultaneously, fork 2 lower ends separate with switch contact 11 under the boosting of spring 9, make switch contact 11 recover the nature shape.The utility model is inhaled pull switch contact 10 or 11 closures with iron core respectively mutually by magnet steel 1 or 4, and is closed rapid, reliable, and the not influence of liquid body fluctuation.
