The utility model has the advantages that the floating ball and the tongue tube are combined, the functions of liquid level switch are realized by utilizing the properties of the tongue tube, and with the addition of a sealing device the work reliability in water is improved considerably and jamming is avoided.

Description

Liquid-level switch
Technical field
The utility model relates to a kind of switching device, specifically a kind of liquid-level switch.
Background technology
At present, the method for measuring liquid level has methods such as infrared type, float-ball type, ultrasonic wave, wherein the float-ball type fluid level measuring instrument use comparatively extensive.But in current float-ball type equipment, not losing as level gauging is good method, but utilizes its transducer as liquid-level switch that a lot of weak points are then arranged.Existing float-ball type liquid-level switch poor sealing, especially be used in the sewage time one longly stop up easily, screens, make liquid-level switch work undesired.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of reasonable in design, compact conformation, Non-Touching Type Liquid Level Switch with low cost are provided, can be in sewage reliably working and avoid stopping up the screens phenomenon.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise ball float, ball float limiter and connecting rod, sealing plug is installed at the connecting rod middle part, ball float is through on the connecting rod, fixture under ball float upper fixing element and the ball float is installed respectively up and down, the ball float limiter is installed on the water tank side plate, the other end and connecting rod lower end are connected, the water tank top board has the hole, and hollow bolt is housed in it, and sealing gasket is installed between the two, thread cap is sleeved on the top of hollow bolt, connecting rod passes hollow bolt, and magnet assemblies is installed at the connecting rod top, and stretches in the thread cap, descending stop is equipped with at the hollow bolt top, the outside of the thread cap buckle closure that is connected, interior dress tongue tube, its two ends connect lead respectively by two binding posts.
The utility model has the advantages that:
Owing in the utility model ball float and tongue tube are combined, utilize the characteristic of tongue tube to realize the function of liquid-level switch, and added sealing device, improve the reliability of in sewage, working greatly and avoided stopping up the screens phenomenon.
Description of drawings
Fig. 1 is the front view of the utility model tongue tube adhesive when hanging down liquid level;
Fig. 2 is the front view of the utility model tongue tube adhesive when higher liquid level;
Fig. 3 is the A-A cutaway view among Fig. 1;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 3 as can be known, the utility model comprises ball float 2, ball float limiter 15 and connecting rod 4, sealing plug 14 is installed at connecting rod 4 middle parts, ball float 2 is through on the connecting rod 4, fixing by fixture under ball float upper fixing element 3 and the ball float 1 respectively up and down, ball float limiter 15 is installed on the water tank side plate 16, and the other end and connecting rod 4 lower ends are connected, play fixation, prevent that ball float 15 from rocking on a large scale in water ball float 15.Water tank top board 13 has the hole, hollow bolt 6 is housed in it, sealing gasket 5 is installed between the two, prevent that the interior effluent seepage of water tank is to water tank, sealing plug 14 then seals up the centre bore of hollow bolt 6 when sewage attains to a high place, prevent that sewage and foreign material thereof from entering upper space, thereby avoided the influence of sewage and foreign material the ball float slide unit.Thread cap 7 is sleeved on the top of hollow bolt 6, connecting rod 4 passes hollow bolt 6, and magnet assemblies 8 is installed at connecting rod 4 tops, and stretches in the thread cap 7, descending stop 11 is equipped with at hollow bolt 6 tops, crosses when low magnet assemblies 8 when liquid level and can be stuck in descending stop 11 places and can not continue and descend.The outside of thread cap 7 buckle closure 9 that is connected, interior dress tongue tube 10, its two ends connect lead 17 respectively by two binding posts 12.
When liquid level was low, as Fig. 1, ball float 2 can spur magnet assemblies 8 downwards, and away from tongue tube 10, the two metal sheets of tongue tube 10 inside can separate, and two leads 17 on the binding post 12 will disconnect at this moment, are equivalent to " opening " state of switch; When liquid level was higher, as Fig. 2, ball float 2 can spur magnet assemblies 8 upward, and near tongue tube 10, the two metal sheets of tongue tube 10 inside can close, and two leads 17 on the binding post 12 just are in conducting at this moment, are equivalent to " closure " state of switch.This explanation liquid level has arrived certain height, will report to the police if two leads connect buzzer.If liquid level goes up, sealing plug 14 seals up the centre bore of hollow bolt 6, prevents that sewage and foreign material thereof from entering upper space, and 5 of sealing gaskets prevent that the interior effluent seepage of water tank is to water tank.
This liquid-level switch is contactless, and has adopted the limit movement of sealing device and ball float slide unit, thereby non-leakage, and the ball float slide unit is not subjected to the influence of sewage foreign material, has improved the stability of work greatly.
