Abstract
The utility model discloses a liquid level switch which can be replaced without draining liquid and comprises a base and a similarly C-shaped support disposed on the base. A plurality of photoelectric detection switches which are arrayed in a line are disposed on one side of the support, a floater is slidably arranged between two bumps of the support, the photoelectric detection switches at corresponding positions can detect the floater when the floater slides up and down, a connecting rod is fixedly disposed on the floater, one end of the connecting rod is provided with a floating ball, and the floating ball is located under the base. The liquid level switch is applicable to detecting or controlling liquid level in containers.
Description
Technical field
The utility model relates to a kind of liquid level control device, relates in particular to a kind of liquid-level switch.
Background technology
Liquid-level switch is a kind of common liquid level detection device in the Level Detection field.Wherein, the tongue tube floating-ball level switch is a kind of the most frequently used liquid-level switch, it comprises: fall L shaped non-magnetic pipe, be provided with tongue tube in the non-magnetic pipe, one end of tongue tube links to each other with holding wire, be arranged with an inside on the non-magnetic pipe and be provided with the ball float of magnet ring, also be provided with upper limit catch and lower limit catch on the non-magnetic pipe, ball float is between upper limit catch and lower limit catch.The tongue tube Floating Ball Liquid Level operation principle of said structure is: the tongue tube floating-ball level switch is installed on the container side wall, the rising of the interior liquid level of container or decline can drive ball float and move up and down, when liquid level is lower than lower limit catch on the non-magnetic pipe, ball float contacts with the lower limit catch, the interior tongue tube of non-magnetic pipe this moment produces the action of adhesive (disconnection), and export to one in external control device by holding wire and open (pass) signal, when liquid level is higher than the upper limit catch, ball float rises and contacts with the upper limit catch, and the interior tongue tube of non-magnetic pipe this moment produces the action of disconnection (adhesive) and exports to a pass of external control device (opening) signal by holding wire.Because whole tongue tube floating-ball level switch all is immersed in the liquid, so when work long hours back or lost efficacy when needing to change of this liquid-level switch, could change after must the liquid in the container all discharging, ten minutes bothers.
The utility model content
Technical problem to be solved in the utility model is: will provide a kind of drain that need not with regard to removable liquid-level switch.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of liquid-level switch, comprise base and the support that is similar to C shape that is arranged on the base, one side of support is provided with several photoelectric detection switch in one line, the rocker piece that slides and be provided with between two projections of support can be detected by the photoelectric detection switch of relevant position when rocker piece slides up and down, and is set with connecting rod on the rocker piece, one end of connecting rod is provided with ball float, and ball float is positioned at the base below.
Described support is provided with waist-shaped hole, and photoelectric detection switch is fixed in the waist-shaped hole by the nut on the photoelectric detection switch;
Pass through screw between described rocker piece and the connecting rod;
Described rocker piece both sides are respectively arranged with the chute that matches with two projections on the support.
The beneficial effects of the utility model are: adopted outside installing type photoelectric detection switch, made also liquid to be drained the not direct contact liq of liquid level detection device when changing liquid-level switch.
Description of drawings
Fig. 1 is the structural representation of the utility model liquid-level switch;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1, base, 2, support, 3, photoelectric detection switch, 4, waist-shaped hole, 5, rocker piece, 6, connecting rod, 7, ball float, 8, projection, 9, chute, 10, screw.
Embodiment
Below in conjunction with accompanying drawing, the utility model liquid-level switch and structure are described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of liquid-level switch, comprise base 1 and the support that is similar to C shape 2 that is arranged on the base 1, on one side of described support 2 waist-shaped hole 4 is set, photoelectric detection switch 3 is fixed in the waist-shaped hole 4 by the nut of its afterbody, conveniently regulate the distance between each photoelectric detection switch 3, can satisfy the demand of multiple detection liquid level.The concrete quantity of photoelectric detection switch can be set according to actual needs.Slide between two projections 8 of the opposite side of support 2 and be provided with rocker piece 5, rocker piece 5 both sides are respectively arranged with the chute 9 that matches with two projections 8, two projections 8 are inserted respectively in two chutes 9, rocker piece 5 just can slide up and down along support 2, be fixed with connecting rod 6 by screw 10 on the rocker piece 5, by the relative position of screw 10 scalable rocker pieces 5 on connecting rod 6, an end of connecting rod 6 is provided with ball float 7, and ball float 7 is positioned at base 1 below.
Operation principle of the present utility model is: the base 1 of the utility model liquid-level switch is fixed on the container, 3 of photoelectric detection switch insert in the electrical equipment control loop, rising or decline along with liquid in container, ball float 7 also rises thereupon or descends, and ball float 7 drives rocker piece 5 by connecting rod 6 and rises or descend, when in the process that rocker piece 5 is rising or descending during through the photoelectric detection switch 3 of relevant position, photoelectric detection switch 3 detects rocker piece 5, the just corresponding signal of outside electrical equipment control loop of giving, control outside electrical equipment simultaneously and carry out a corresponding action, promptly the liquid in the container is carried out supply, take away or quit work.
The utility model has the advantages that: adopted outside installing type photoelectric detection switch, so that liquid level detection device critical piece contact liq not, this has just reduced the corrosion of liquid to checkout gear, significantly prolonged the service life of liquid-level switch, and when changing liquid-level switch, also liquid need not be drained, only need to pull down behind the base on the container getting final product that whole liquid-level switch is withdrawn and more renewed.
Claims (4)
1. liquid-level switch, comprise base and the support that is similar to C shape that is arranged on the base, it is characterized in that: a side of described support is provided with several photoelectric detection switch in one line, the rocker piece that slides and be provided with between two projections of support, when sliding up and down, rocker piece can be detected by the photoelectric detection switch of relevant position, be set with connecting rod on the rocker piece, an end of connecting rod is provided with ball float, and ball float is positioned at the base below.
