Comb idler is made by plain roller with welded spiral steel. It's used for cleaning conveyor belt. comb idler is setting in the position where unwanted debris will stick to the belt seriously. It removes the sticky material to keep belt clean and running stable, avoid misalignment. Usually, it's used in conjunction with sleeve rollers at the beginning of return run. comb idler roller diameter is fromφ76 to φ219
Comb Idler used in acid and alkali resistant industry of conveyor, comb idlers can replace the metal roller , nylon roller , long life , easy installation , custom center smooth transportation , reduce conveyor belt deviation and protection conveyor belts and other characteristics . comb roller superior performance than traditional iron roller , low wear coefficient , the proportion of small , light weight , easy to replace , and the low noise , smooth operation , more suitable for the working environment of the production conditions , high service life.

Description of the Invention The utility model relates to the field of intelligent remote direct-read valve control water meter, in particular to a novel intelligent water meter valve control box.
BACKGROUND OF THE INVENTION At present, in the manufacture of smart water meters, the main core components are mainly valve-controlled motors, control circuit PCB boards, and valve control housings. At present, the valve control box on the market does a good job of protecting the valve motor, but the PCB control circuit PCB board protection is not perfect, especially in the waterproof part.
SUMMARY OF THE INVENTION The technical problem solved by the present invention is to provide a novel wireless intelligent water meter valve control box to solve the above-mentioned problems in the background art.
The technical problem solved by the utility model is mainly a novel wireless intelligent water meter valve control box realized by adopting the following technologies, comprising: a motor box, a valve control outer box and a valve control chassis. The motor box is arranged Valve-controlled outer box, valve-controlled box and valve-controlled chassis connected and fixed. 
The figure is a schematic diagram of the utility model
The valve control box includes a valve control box upper cover and a valve control box lower cover. The motor box is a radio box. The radio box is provided with a valve-controlled motor box antenna plug, a motor box cover, a motor box bottom cover, a valve motor, a valve-controlled wireless PCB board, a battery, a valve-controlled wireless PCB board and a battery. And connected with the motor, the valve motor and the bottom cover of the motor box are screwed and glued and sealed.
Due to the adoption of the above structure, the utility model has the following advantages: solid and reliable, and can prevent internal components from being damaged under external impact; the design adopts double-layer design and double gluing, and can play a good waterproof role, and the waterproof level can reach IP68. .
Compared with the prior art, the beneficial effect of the present invention is that: using a two-layer design, the double grouting will not harm the valve motor and the circuit board even if it is impacted by an external force or soaked in water, and the service life is greatly improved.
