Abstract
The utility model relates to an automatic liquid level controlling and warning device, particularly a floating ball type fluid level controller used for the water level control of boilers and warning. The utility model comprises a magnetic control switch which is composed of a base, a front supporting frame, a rear supporting frame, a rocking plate, magnetic steel and a cover box and arranged in an adjusting box. Because the magnetic control switch is designed into an energized structure closed and cut off by a single contact, the utility model solves the problem that the double-contact has the possibility of being not in simultaneous contact and causes poor sensitivity and reliability. Because the magnetic control switch designed by the utility model has few contact, the utility model has the advantages of simple structure and flexible and reliable action. As a consequence, the utility model can be combined into multifunctional floating ball type fluid level controllers of various standards.
Description
Technical field
The utility model relates to a kind of automatic control of liquid and warning device, particularly a kind of float-type liquid level controller that is used to control boiler water level and warning.
Background technology
Contact magnetic switch in the float-type liquid level controller adjusting tank is a critical component of the present utility model, and it can be provided with many group magnetic switchs according to difference in functionality.Now its magnetic switch of the float-type liquid level controller of Sheng Chaning two pairs of contacts generally being designed to cooperatively interact closed or disconnect realized water level control and controlling alarm, when water level or alerting signal closure or disconnection, pair of contact must contact simultaneously and could connect the contact with another, error or part deformation have been installed if run into, be easy to make two pairs of contacts not contact simultaneously, so break-make control signal sensitivity and poor reliability.Also exist because of shortcomings such as the many complex manufacturing technology in contact simultaneously.
Summary of the invention
Deficiency in view of above-mentioned prior art existence, the utility model provides a kind of match magnetic switch of structure of single contact that utilizes to carry out closure or disconnect the float-type liquid level controller of control, its objective is to solve that double-contact might not contact simultaneously and the problem that causes sensitivity and poor reliability.
The utility model is that the technical scheme that its technical matters of solution is taked is: float-type liquid level controller comprises by base, front and back support, rocker, the magnetic switch that magnet steel and cover box constitute and placing in the adjusting tank, it is characterized in that: two lug plates of contact-carrying respectively are housed on the base between the front and back support and stretch out by the base bottom, the contact is equipped with at rocker and two ends respectively has a conducting strip riveting of protruding supporting pieces to be in the same place with both sides are middle, two contacts on the conducting strip are communicated, work in coordination in contact on the conducting strip and the contact on the base, have corresponding through hole in the bottom of front and back support, riveting has conducting strip in the two through hole, insert respectively in the two through hole that riveting has conducting strip with the supporting pieces of rocker riveting conducting strip both sides together, supporting pieces rotates in two through hole, make two closings of contact or disconnection on two contacts on the conducting strip and the base, the lug plate that links to each other with conducting strip in the after-poppet through hole also is housed on base, three lug plates are connected to lead-in wire respectively, base and after-poppet are one, fore-stock is movable supporting frame and leaves a groove by the base leading flank and insert, the leading flank of base also is equipped with label, on label, be useful on the mark of difference in functionality, the top of front and back support and the middle part of magnet steel have corresponding through hole, and by through hole magnet steel is placed the top of front and back support by a minor axis, magnet steel can rotate around minor axis, and the cover box is buckled and covered on the base.
The float-type liquid level controller that adopts above-mentioned single contact structure magnetic switch to constitute, owing to reduced the contact, it is simpler to make it structure, the on/off signalizing activity that is used for control water level and warning is sensitive more, reliable.Its operating principle is to utilize between the magnet steel magnetic pole to produce interactional principle and design.Because the utility model is equipped with main magnet steel on the ball float assembly, the barrel of float component is welded with the flange that is communicated with boiler furnace, and ball float drives main magnet steel and rises or descend with SEA LEVEL VARIATION in the floating drum.When main magnet steel and magnetic switch approach, because the magnetic pole interphase interaction makes magnetic switch rapid closing or disconnection, reach the purpose that circuit switches, realize water level control.
