Water Control Principle
Through the server, the cash currency is converted into electronic money and stored in the electronic wallet of the IC card. When the consumer needs to consume, only the IC card can be placed on the water control machine to be consumed, and the consumption amount can be deducted from the card to complete the entire transaction. process. No cash involved in the transaction process, truly intelligent consumption.
How to choose a water controller
First, a strong waterproof performance Water control environment where the environment is relatively humid, often in the use of water directly splashed on the water control machine, water control machine waterproof performance is an important indicator of the life of the water control machine one. All the circuit parts of our company's water control machine are all encapsulated using electronic potting and sealing technology. The internal circuit board of the company is connected to the flow meter and the solenoid valve connector wire without connectors. The professional machine can still be used to bubbling water in the water. The normal operation makes the system have highly reliable operating conditions.
Second, anti-theft water function The phenomenon of water theft is closely related to investment returns for investors. Failure to prevent the occurrence of such phenomena will greatly affect the rate of return, which may lead to serious investment losses. Therefore, the anti-water stealing function of the water control machine is also very important.
Third, the single model: no networking, data acquisition can understand each water control water situation through the data acquisition card to collect information on the water control machine can be used on the water control machine is well aware of the situation. It can collect the total amount of water used by the water control machine, the total amount of water used, etc.
IV. Appropriation: Adopting the form of grants to improve the convenience of management The system will realize the function of depositing through the allocation of funds. The amount of money allocated to the user's IC card from the appropriator will not be reported to the user and will not be refunded. (If the IC card is inadvertently lost, The user account information and balance information are still retained) so that the user's loss after the loss of the IC card is minimized. Through student funding, it can automatically collect the consumption data of the water control machine, hand it over to the computer management machine, check the amount of charge for each water control machine, and use the amount of water.
V. Networked type: Real-time query of the use of water control machines and the balance of the IC card on the network can real-time query of all the water consumption real-time consumption data (such as the amount of charges, water consumption, etc.) and summary. You can also check the recharge amount, usage amount, card balance, etc. of each IC card. It is the most perfect management method.
WAFER TYPE DOUBLE DISE CHECK VALVE
Wafer check valve is also known as reverse flow valve, check valve, back pressure valve and one-way valve. This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline. The valve used to prevent the backflow of the medium belongs to an automatic valve.
Its main function is to only allow the medium to flow in one direction and prevent the flow in the opposite direction.
, Prevent the reverse rotation of the pump and the drive motor, and the discharge of the container medium. Check Valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure. Check valves are used in piping systems,
The check valve is a valve that automatically opens and closes the valve flap depending on the flow of the medium itself, allowing the medium to flow in one direction, and plays an important role in protecting the pipeline machinery and equipment from water hammer damage. Usually, this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincident valve flap of the valve flap act on the valve seat, thereby cutting off the flow. The working characteristics of the check valve are that the load changes greatly, the opening and closing frequency is small, and once it is put into the closed or open state, the applicable period is very long, and it does not require the movement of moving parts. But once there is a "switching" requirement, it must be flexible,
Wafer check valve, the valve body is cast iron or cast steel, and the valve disc can be made of metal, depending on the performance requirements. The disc can be of all-metal construction, in the form of a rubber pad or rubber ring inlaid on the disc holder, or with a synthetic overlay.
Choose different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
