Abstract
The utility model discloses a floating ball employing a mercury switch, comprising a floating ball installing seat (7) and a shell (1) sealed and arranged on the floating ball installing seat (7). A switch seat (4) located on the floating ball installing seat (7) is arranged in the shell (1) and is equipped with two electrodes (5) which are parallelly arranged at intervals, the lower ends of the two electrodes (5) are both embedded downwards in the switch seat (4) and are respectively connected with one ends of different conducting wires (9), and the other ends of the conducting wires (9) penetrate the underside of the floating ball installing seat (7) and are extended downwards; the switch seat (4) is equipped with a glass cover (3) in seal connection with the switch seat (4), a liquid-state mercury (6) is placed in a cavity formed by the glass cover (3) and the switch seat (4), and the liquid mercury (6) and the two electrodes form the mercury switch. The floating ball employing the mercury switch of the utility model is simple in structure, convenient in installation and use and stable in running, possesses the characteristics of corrosion resistance and wide application range, and is suitable for popularization and use.
Description
Technical field
The utility model relates to a kind of fluid level control device, specifically the ball float of a kind of long service life, employing mercoid switch applied widely.
Background technology
In the prior art, the mode of liquid level control is a lot, and commonly used is the ball float control mode.When adopting this mode, because ball float need to be placed in the liquid of multiple different in kind, therefore the applicable performance of ball float is had relatively high expectations.Aspect the switch of ball float employing, commonly used is the Hall magnetic switch at present, the Hall magnetic switch is installed in the middle of the sticking plaster, puts a hollow metal sphere in the outside of sticking plaster, and the action that triggers the middle Hall magnetic switch of sticking plaster by the position of hollow metal sphere realizes ball float control.Make because above-mentioned hollow metal sphere adopts metal, therefore be placed on for a long time hold in the water corrosion-prone, just more serious if acid solution then corrodes; Be embedded in addition the Hall magnetic switch in the sticking plaster, it also is with good conditionsi, first: Hall magnetic switch and hollow metal sphere must have certain distance just effective, if be in the many occasions of the abominable foreign matter of environment, so because being easy to be filled up by dirt between hollow metal sphere centre bore and the Hall magnetic switch, cause up and down vibration and can't reach the required coverage of inner Hall magnetic switch action of hollow metal ball; Second: the limitation of installation, Yin Huoer magnetic switch must be contained in the sticking plaster, and inconvenience must in the position at the control point of required liquid level, so just have been brought to installation in the position when hollow metal sphere is installed; The 3rd: the Yin Huoer magnetic switch adopts magnetic micro switch, and the limited and contact of its contact capacity is easy to adhesion and is failure to actuate.
Summary of the invention
The purpose of this utility model is the defective for prior art, and the ball float of a kind of long service life, employing mercoid switch applied widely is provided.
The purpose of this utility model solves by the following technical programs:
A kind of ball float that adopts mercoid switch, comprise that ball float mount pad and sealing are installed in the shell on the ball float mount pad, it is characterized in that being provided with in the described shell switch base that is positioned on the ball float mount pad, switch base is provided with two electrodes that spaced and parallel arranges, the lower end of two electrodes is all straight down in the flush switch seat and link to each other with an end of different conductor respectively, and the other end of wire passes the bottom surface of ball float mount pad and to downward-extension; Switch base is provided with the cloche that links to each other with its sealing, is placed with liquid mercury in the cavity that cloche and switch base consist of, and liquid mercury and two electrodes consist of a mercoid switch.
The place, bottom surface of described ball float mount pad is provided with the water-stop that is nested with on wire.
Be provided with the protective cover that is positioned at ball float mount pad upside between described shell and the cloche, link to each other along sealing with the upper wall of ball float mount pad under the described protective cover.
Described shell adopts ABS plastic to make.
The utility model has the following advantages compared to existing technology:
The utility model becomes one by ball float shell and the mercoid switch that ABS plastic is made, when ball float vertically arranges, liquid mercury is with the overlay switch seat and replace the contact connecting line that two electrodes that arrange on the switch base are communicated with, namely so that mercoid switch is closed, then just can locate the height of liquid according to the length of wire, easy to install and stable.
The utility model is simple in structure, corrosion-resistant, long service life and applied widely, suitable promoting the use of.
