Vertical float switch

Abstract

The invention relates to a vertical float switch which comprises a closed hollow housing, wherein a microswitch is arranged in the housing, a hollow float is arranged outside the housing, and the vertical float switch is characterized in that a Y-shaped rocker arm which can rotate horizontally for controlling the microswitch is further arranged in the housing, a rod-shaped suspension rod which can move up and down is further arranged in the housing, the lower part of the suspension rod extends out of the housing and is connected with the float, and magnets are arranged at two free ends of the rocker arm and the upper part of the suspension rod. The housing of the vertical float switch can be detached, the number of the magnets is increased, and a sealing liquid is increased in the position of an output conducting wire, therefore, compared with the prior art, the vertical float switch has the advantages of simplicity in manufacturing, convenience in mounting, long mechanical service life and electrical service life, stability in signal transmission, wide applicable spatial range and the like.

Description

[0001] technical field [0002] The invention relates to a vertical float switch. Background technique [0003] At present, most of the water industry uses liquid level float switches to control the water level. The principle of the liquid level float switch is that the float moves up and down according to the rise and fall of the water level, thereby controlling the switching action inside the float switch, and using the output signal to control the action of the water pump or other electrical components, and finally meet the needs of the user. The float switch has simple structure, reliable output and low cost, so it is widely used in water treatment, clean water tank, sewage tank, liquid chemical raw materials and other places, providing a lot of convenience for the water supply and drainage industry, sewage treatment industry, chemical industry and other industries. [0004] The liquid level float switch is usually composed of a simple sealed casing, a float set in the ...

AI Technical Summary

Problems solved by technology

However, this kind of float switch still has some shortcomings. Because the single magnet has a strong adsorption force with the iron sheet, it is not easy to separate. Disconnect, which increases the cost of the product, and the weight is not easy to control, which will affect the accuracy of the switch, and the reliability is poor; at the same time, the iron sheet is easy to oxidize, rust, and pollute the environment, so it is not easy to use in drinking water. In addition, the position of the floating ball cannot be adjusted, which is not suitable for different use environments; the single magnet is attracted, the suction is insufficient, and the reliability is poor; the sealing of the output cable is not considered
