Problems solved by technology

[0002] The water level controller in the prior art usually controls the opening and closing of the switch by setting a delay relay and a circuit, which increases the number of parts of the existing water level controller and complicates the structure, which leads to an increase in cost
Prone to loss of production in areas with unstable power supply
[0003] However, the existing non-electrically driven water level controllers have the disadvantages of large volume, large starting water pressure difference, complex structure and high failure rate.

Embodiment 1

[0035] A water level controller, comprising an outer floating body 1, an inner floating body 2, and an isolation box 3, the outer floating body and the inner floating body can rise or fall with the change of the water level, the isolation box has a water inlet control chamber, and the mouth of the water inlet control chamber faces downward Set on the bottom of the isolation box, the water inlet control cavity has a water inlet 4, the inner floating body is hinged to the water intake control cavity, and the upper wall of the water intake control cavity is provided with an air hole 5, and the outer floating body is arranged above the air hole. When the value is fixed, the outer floating body will block the air hole, and when the water level rises to the set value, the inner floating body will rotate around the hinge to block the water inlet.

[0036] Preferably, the water inlet control chamber includes a floating body chamber 6 and an auxiliary air intake chamber 7, a partition w...

Embodiment 2

[0049] The difference between this embodiment and Embodiment 1 is that the outer floating body has an articulated arm 18 and a suspension 19, one end of the articulated arm is hinged on the isolation box, the other end is connected with the suspension, and the lower side wall of the articulated arm is provided with a useful In the clogged part that blocks the pores when the water level drops. The blocking part is a rubber blocking block 20 .

[0050] Preferably, a third suspension cavity 21 is opened on the suspension body, and the opening of the third suspension cavity is opened on the bottom surface of the suspension body.

[0051] Preferably, the water inlet control chamber also includes a water inlet chamber 22, a floating body movable opening 23 is opened between the water inlet chamber and the floating body chamber, one side of the inner floating body is hinged to the water inlet chamber through the floating body movable opening, and the inner floating body is another O...

Abstract

The invention discloses a water level controller comprising an external floating body, an internal floating body and an isolation tank. The external floating body and the internal floating body can rise or fall along with the change of the water level. The isolation tank is provided with an inlet water adjustment and control cavity. The cavity port of the inlet water adjustment and control cavity is downwardly arranged on the bottom surface of the isolation tank. The inlet water adjustment and control cavity is provided with a water inlet. The internal floating body is hinged in the inlet water adjustment and control cavity. The upper wall surface of the inlet water adjustment and control cavity is provided with an air hole. The external floating body is arranged above the air hole. When the water level falls to a set value, the external floating body plugs the air hole. When the water level rises to the set value, the hinged part of the internal floating body rotates so as to plug the water inlet. The effects that automatic water supplementing is performed when the water level is low and water intaking is automatically stopped when the water level is high can be realized without electric power so that the water level controller has the advantages of zero energy consumption, low fault rate and simple structure and can avoid production loss caused by instable power supply in the regions of instable power supply especially.

Description

technical field [0001] The invention relates to a control device, in particular to a water level controller. Background technique [0002] The water level controller in the prior art usually controls the opening and closing of the switch by setting a time-delay relay and a circuit, which increases the number of parts and complicates the structure of the existing water level controller, resulting in increased cost. In areas with unstable power supply, it is easy to cause production loss. [0003] However, the existing non-electrically driven water level controller has the disadvantages of large volume, large starting water pressure difference, complex structure and high failure rate. Contents of the invention [0004] Aiming at the technical problems existing in the prior art, the purpose of the present invention is to provide a water level controller. [0005] The purpose of the present invention is achieved through the following technical solutions: a water level contro...
