Description
Technical field
The utility model relates to a kind of liquid level control switch, the novel liquid level control switch of particularly a kind of suitable high temperature, high viscosity, non-conductive liquid level.
Background technology
In fields such as pharmacy, chemical industry, when the reaction pot liquid is high temperature, high viscosity, non-conductive liquid, the control of its liquid level will be the work of a complexity.Present common way is, adopts the float-ball type control switch to control liquid level, but the following defective of existing float switch ubiquity: the first,, at high temperature lost efficacy easily because its magnetic reed switch is installed in the tank body of sealing.The second, ball float is when guide rod rises, and viscous liquid rises with ball float and sticks guide rod, and ball float is difficult for falling, and causes control fails.Three, be only applicable to have the liquid level control of certain electric conductivity, then inoperative for non-conductive liquid.Four, guide rod and ball float carry a large amount of viscous liquids, not easy cleaning.
Utility model content technical problem to be solved in the utility model is, overcome the deficiency of above-mentioned existing method and control switch, and provide a kind of novel external control type floating-ball level switch, it can effectively control the liquid level of high temperature, high viscosity, non-conductive liquid, and stable performance, easy to use, cleaning.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme.
A kind of external control type floating-ball level switch comprises ball float, it is characterized in that: comprise that also the body of sealing and upper end are fixed on intrinsic inner guide; Be fixed with the outer guide rod that is slidingly connected with inner guide in the upper end of ball float, this hole of Kong Bingyu that outer guide rod passes end cap under the body is slidingly connected; Two magnetic reed switchs up and down are installed on inner guide, promptly go up magnetic reed switch and following magnetic reed switch, mobile magnetic reed switch is installed on the guide rod outside; Last magnetic reed switch, following magnetic reed switch and mobile magnetic reed switch all are arranged in the body.
Outer guide rod is a tubulose, is similarly the fixing inner guide slip cap of tubulose and upper end and bodies top and is contained in the outer guide rod.
The resistance string that is arranged above and below also is installed on inner guide; Resistance string is fixed on the inwall of inner guide.
Last magnetic reed switch and following magnetic reed switch are fixed on the inwall of inner guide.
The lead wire set of last magnetic reed switch, following magnetic reed switch, mobile magnetic reed switch and resistance string is drawn from bodies top through the inner guide inner chamber.
The bodies top opening part seals by resin glue.
Be threaded between bottom end cover and the body.
The body lower end has and is used for the external screw thread or the flange that are connected with tank body.
Good effect of the present utility model is: (1), magnetic reed switch is placed in the body cavity of sealing, overcome the problem of hot environment lower magnet loss of excitation, (2), the first half of the whole and ball float of guide rod does not all immerse in the liquid, avoided high viscosity liquid bonding guide rod and influenced the drawback that ball float floats, and be convenient to clean.(3), be applicable to conduction and the control of the liquid level of non-conductive liquid, range of application is wider.(4), can dynamically show liquid level more intuitively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, body 5 upper port are used for fixing the upper end of the inner guide 3 of tubulose, and lead-out wire group 9 derives the back from the upper end of inner guide 3 and with resin glue 10 inner guide 3 upper orifices sealed, and lead-out wire group 9 is fixing.Body 5 lower port are by bottom end cover 12 sealing that is spirally connected, and body 5 inside are a closed cavity.
The outer guide rod 2 of tubulose is welded on ball float 1 upper end of Stainless Steel Shell, and inner guide 3 is sleeved in the outer guide rod 2 and slides up and down in the guide rod 2 outside.The Kong Bingke that outer guide rod 2 passes body bottom end cover 12 slides up and down along this hole inwall.Two magnetic reed switchs up and down are installed on inner guide 3, promptly go up magnetic reed switch 8 and following magnetic reed switch 11, guide rod 2 tops are fixed with mobile magnetic reed switch 6 outside; Last magnetic reed switch 8, following magnetic reed switch 11 and mobile magnetic reed switch 6 all are arranged in body 5 closed cavities.
The resistance string 7 that is arranged above and below also is installed on inner guide 3; Resistance string 7 is fixed on the inwall of inner guide 3.Last magnetic reed switch 8 and following magnetic reed switch 11 also are fixed on the inwall of inner guide 3.
During installation, the last magnetic reed switch 8 that to often open earlier, down magnetic reed switch 11 and resistance string 7 are packed on the inwall of the inner guide 3 of holding the hole successfully, and with hole and lead glue good seal, inner guide 3 is connected with outer guide rod 2 and mobile magnetic reed switch 6 is pushed in body 5 cavitys again, then bottom end cover 12 is packed in the body 5, and good seal.
This device vertically is contained in the upper end of the liquid tank of a sealing, when floating ball float 1, liquid moves up, mobile magnetic reed switch 6 sends when arriving the position of upper magnetic reed switch 8 and stops the liquid feeding signal, when falling the position of extremely following magnetic reed switch 11 after rise, send startup liquid feeding signal, with liquid level in the automatic control jar.
Along with ball float 1 moves up and down, resistance in the resistance string 7 and mobile magnetic reed switch 6 are responded to, and send analog signal, by display unit reflection liquid level dynamic height.
