November 2, 2013 - Shanghai - The driving device for the water valve could be concluded into three watervalve.org types which are the electrical device, hydraulic device and pneumatic devices. Today, the famous China water valves manufacturer Shanghai Chamgu valve which website is www.watervalve.org would introduce with people the advantage and disadvantages about these three types of driving device for the water valves.
The first type should be the electric devices. The advantage of the electric device could be concluded into below points. The first strong point should be the strong and it could not be affected by the changing of the temperature. Second, the output torque of this device has large. Thirdly, the controlling for this device is very. People could free use DC, AC, shortwave, pulse and other signals. It would be suitable for amplification, memory, logic and calculations and etc. Last, the installation and maintenance for the electric device would be also very easy.
The disadvantage of the electrical driving device is also very obviously. First, the structure of this kind of device is very complicated. Second, the mechanical efficiency is low which is only from 25 percent to 60 percent. Thirdly, the outputting speed of the electrical driving device for the water valve could not be too large. The last disadvantage is that the electrical device would be easy to be influenced by the supplying voltage and the changing of the frequency.
The second type should be the hydraulic driving device. Advantages this would be very obviously. First, the hydraulic device has simple structure, compact and small space. Second, the outputting force is very large. Thirdly, it would be easy to access low or high speed and it can be controlled by remote automatic. Fourth, as the viscosity of the hydraulic oil, this machine would have high efficiency. On the other hand, the hydraulic driving for water valve could also have the function of self-lubricating and antirust properties. The disadvantage is that the oil temperature changes could caused into changing of oil viscosity. On the other hand, the hydraulic components and pipes of the China water valve would be easy to leak.
The third type should be the pneumatic driving devices of the China water valves. The pneumatic driving irrigation valve device has simple structure and the resource of air is easy to be obtained. Second, this kind of pneumatic driving device can be installed the governor which could adjust the speed. On the other hand, the big gas compressibility could let this device has great flexibility when it has been closed.
The disadvantage of this device is that the structure of this should be larger when it compare with the hydraulic driving device. In that case, it could not suitable for large-diameter high- pressure valves.
