Water level switch calibration detector

Abstract

The invention discloses a water level switch calibration detector that comprises a water storage tank, a base and a measuring box; a water storage tank is mounted at one end of the top end of the base; a measuring box is mounted at the top end of the base away from the water storage tank; a lifting box is vertically installed in the middle of the upper end of the side, away from the water storagetank, of the measuring box. A sliding groove is formed in the middle of the side, close to the measuring box, of the lifting box, a connecting block is arranged in the sliding groove in a sleeved mode, a hinge plate is horizontally installed on the side, away from the lifting box, of the connecting block, semicircular clamps are horizontally hinged to the two sides of the end, away from the connecting block, of the hinge plate, and liquid level switches are arranged in the semicircular clamps. By rotating the second rotating handle, the rubber plate and the water pressing plate slide in the sliding way through the sliding block and slowly and stably descend, clear water in the water storage tank is slowly injected into the measuring box through the water passing pipe, and therefore the situation that measurement accuracy is affected due to violent shaking during water adding or water draining is avoided.

Description

technical field [0001] The invention relates to the technical field of water level switches, in particular to a calibration and detection machine for water level switches. Background technique [0002] The water level switch, as the name implies, is a switch used to control the water level. It is mainly divided into contact type and non-contact type in form. The commonly used non-contact type switch is capacitive type liquid level switch. Widely, electrode type liquid level switch, electronic liquid level switch, and capacitive liquid level switch can also be realized by contact method. In order to calibrate the water level switch, a calibration detection machine is usually used for calibration detection. The traditional calibration detection machine It can basically meet people's needs, but there are still some problems, the specific problems are as follows: [0003] 1. Traditional water level switch calibration detectors of this type do not have a level detection mechanis...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a water level switch calibration detector to solve the problems in the above background technology that there is no level detection mechanism, the water level switch is moved directly by hand, and the water addition or drainage is unstable.
