A fully automatic water level controller

Abstract

The invention discloses a fully automatic water tower water level controller. The fully automatic water tower water level controller adopts the technical scheme that the fully automatic water tower water level controller comprises a main valve body, wherein a hollow cavity for allowing water flows to pass is arranged in the main valve body, and a water inlet and a water outlet are formed in the main valve body. The fully automatic water tower water level controller is characterized in that an upper sealing elastic body and a regulating spring tightly pressed on the upper sealing elastic body are arranged above the hollow cavity of the main valve body, a lower sealing elastic body is arranged under the hollow cavity of the main valve body, a linkage pull rod is arranged between the upper sealing elastic body and the lower sealing elastic body for forming the linkage matching, an inner chamber is arranged in the hollow cavity of the main valve body, the inner chamber is provided with an inner water inlet towards the lower sealing elastic body and an inner water outlet communicated with the water outlet, the hollow cavity of the main valve body is divided into an upper pressure cavity, a lower pressure cavity, an outer water inlet cavity and an inner water inlet cavity by the upper sealing elastic body, the lower sealing elastic body and the inner chamber, an upper flow guide hole is formed between the upper pressure cavity and the inner water inlet cavity, and a lower flow guide hole is formed between the lower pressure cavity and the outer water inlet cavity.

Description

technical field [0001] The invention relates to a water level controller of a water tower. Background technique [0002] The water level controller of the water tower refers to the instrument applied to the water tower for automatic water level control. [0003] The water level controller of the water tower is mainly divided into mechanical type and electromagnetic type. The mechanical type such as the lever type float water inlet valve is composed of a float device, a check valve, a tee, an outer wire and other accessories. The disadvantages of this kind of controller are: 1. The structure is complex, requiring professionals to install, which is time-consuming and expensive; 2. The failure rate is high, such as water tower overflow is prone to occur, the vibration of the lever float is large when it is about to close, sealing deviation, one-way stop If the return valve takes a long time, the valve plate will be deformed or get stuck by dirt, and the seal will not be tight...

Problems solved by technology

The disadvantages of this kind of controller are: 1. The structure is complex, requiring professionals to install, which is time-consuming and expensive; 2. The failure rate is high, such as water tower overflow is prone to occur, the vibration of the lever float is large when it is about to close, sealing deviation, one-way stop If the return valve takes a long time, the valve plate will be deformed or get stuck by dirt, and the seal will not be tight; 3. Difficult maintenance, such as when the water tower overflows, it is difficult to judge whether it is a float leak or a check valve leak; 4. It will pollute The water body, the floating ball is in direct contact with the water body, and dirt will be produced for a long time, which will affect the water quality

Electromagnetic type, such as solenoid valve, needs power supply, and cannot work when power is off, and the cloth wire is easy to burn out, and it is not safe
