Abstract
The utility model relates to a liquid level controller, comprising a base, a lever, a bearing rod, a floating ball, a control switch and a cover. The liquid level can be controlled only by using a control switch fixed on the base and depending on a float on-off actuator element. The change of elevation of the liquid level can be controlled by regulating a banking screw and changing the length of the bearing rod. The utility model avoids the damage of a motor pump or the controller caused by the fluctuation of the liquid level and has the advantages of simple structure and stable and reliable performance. The utility model can be widely used in the device in the industrial and mining enterprise, the agriculture irrigation, the aquaculture, the household water-tower and water tank, etc.
Description
The utility model relates to a kind of control or regulating system of on-electric variable of liquid level.
Fluid level controller has transistor type, electromagnetic type and lever machinery formula several at present.Wherein lever fluid level controller conductive magneto-conductive character of not being subjected to level control amplitude and medium etc. influences, and is used widely.A kind of by being loaded on tongue tube in the ball float fluid level controller that assembly constitutes of posting a letter, its good airproof performance, but the easy virtual connection of the lead of drawing from ball float or fracture cause misoperation.The another kind of fluid level controller that adopts pulling switch along with the prolongation of operating period, is difficult to overcome pulling switch malfunctioning inherent shortcoming easily itself, and reliability is reduced.
The purpose of this utility model is to provide a kind of simple in structure and stable, fluid level controller that reliability is higher.
The purpose of this utility model adopts following technical scheme to realize: fluid level controller comprises base, lever, pole, ball float, control switch and cover cap, control switch is fixed on the base, the support that is arranged on the base is equipped with a lever, the stop screw that links to each other with the contact support of control switch is positioned at an end of lever, it is outer and connecting a pole that the other end of lever stretches out cover cap, and ball float is equipped with on the pole top.
Fluid level controller is installed on the container inner wall.Prescribe a time limit when liquid level rises to, the buoyancy of ball disconnects control switch by lever, cuts off executive component, and the power supply as electromagnetic pump, electric-motor pump stops feed flow.Prescribe a time limit when liquid level is lower than down, the deadweight of ball float makes the contact support of lifting and heading on control switch on the lever end, the control switch closing of contact, and executive component is connected feed flow.So go round and begin again, finish the automatic control of liquid level.
Electric control system of the present utility model only adopts a control switch, and conversion strut lengths and adjusting stop screw are controlled the heave amplitude of liquid level.Simple in structure and can eliminate the misoperation that causes because of liquid fluctuating, avoided the damage of controller and executive component, working stability is reliable.
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Accompanying drawing 2 is the structural representation that sheds behind cover cap, pole and the ball float of the present utility model.
Accompanying drawing 3 is a kind of electrical schematic diagram of single-phase electricity pump fluid level controller.
Accompanying drawing 4 is a kind of electrical schematic diagram of three-phase electricity pump fluid level controller.
Embodiment:
Control switch (1) is selected LX19K-B type travel switch for use.Base (2), support (3), lever (4), cover cap (9) and binding post (10) are made by ABS plastic or bakelite.Pole (7) is adopted metal material.Ball float (8) useable glass or ABS plastic are made.Determine the length of pole (7) according to the heave amplitude of control liquid level, after regulating nut on the stop screw (6) and making controller be in optimum Working, stop nut is cemented fixing with glue or epoxy resin.For the fluid level controller that adopts the three-phase alternating current pump, the contactor J in its accompanying drawing 4 selects 380 for use
V10
AEJD type A.C. contactor.The fluid level controller that is used for discharge liquid only needs the electric-motor pump power input by the changing-over of A binding post to the B binding post, and its structure need not done any change.The utility model is widely used in devices such as industrial and mining enterprises, agricultural drainage and irrigation, aquaculture and family expenses water-tower water tank.
Claims (1)
