Function introduction of electric PVC / PP plastic ball valve
It is a kind of pipeline pressure element for industrial automation process control. It is usually used for remote opening, closing (turning on and off) control of pipeline media.
Features: With integrated structure, single-phase power supply AC220V and DC power supply 24VDC can control the operation. Small size, light weight, reliable performance, simple matching, large flow capacity, etc.
Working characteristics: It is suitable for process occasions and fluid control systems where the pressure difference in the pipeline is large and the sealing requirements are strict.
Working temperature: -20 ℃ to + 150 ℃ (+ 250 ℃ special seal).
Working pressure: PN10, 1MPA
Material and application area of electric PVC / PP plastic ball valve
The technical term for electric plastic ball valves is called rigid polyvinyl chloride electric plastic ball valves. In addition to UPVC materials, there are three materials: RPP, CPVC, and PVDF. According to different material characteristics, unrecognizable operating conditions are selected. UPVC electric plastic ball valves are used in seawater Much larger than other materials, we have already introduced the characteristics and use environment of UPVC ball valve, not much to introduce here, now focus on the characteristics of UPVC plastic ball valve after installing electric.
Electric plastic ball valve is an important electric actuator in industrial automation control system. Electric plastic ball valve is a valve that rotates around the axis of the valve stem according to this moving form of the valve disc. The change of the valve seat port is proportional to the valve stroke. It is mainly used to cut off or connect the medium in the pipeline. It can also be used for the regulation and control of fluids. It is a kind of pipeline pressure element for industrial automation process control.
Basic structure and working principle of electric PVC / PP plastic ball valve
The electric plastic ball valve is simple in structure and consists of only a few parts, saving data consumption; small size, light weight, small installation size, small driving torque, pressure regulating valve, easy and agile operation, only need to rotate 90 ° to quickly Opening and closing; and also has a good flow regulating effect and closed sealing characteristics, in the application range of large and medium caliber, low pressure, electric ball valve is the dominant valve situation. When the electric ball valve is in the fully opened position, the thickness of the ball is the only resistance when the medium flows through the valve body, so the pressure drop occurring through the valve is small, so it has good flow control characteristics. The electric ball valve has a soft-sealed Teflon type. If an electric ball valve is requested to be used as a flow control, it is important to accurately select the size and type of the valve. The construction principle of the electric ball valve is particularly suitable for manufacturing large-caliber valves. Electric ball valves are not only widely used in general industries such as petroleum, gas, chemical, and water treatment, but also used in cooling water systems of thermal power stations.
There are two types of commonly used electric ball valves: socket-type electric ball valves and flange-type electric ball valves. The socket-type electric ball valve is connected between the two pipeline flanges with stud bolts. The flange-type electric ball valve is provided with a flange on the valve, and the two ends of the valve are bolted to the pipeline flange. The strength performance of the valve refers to the ability of the valve to be subjected to the pressure of the medium. The valve is a mechanical product subject to internal pressure, so it must have sufficient strength and rigidity to ensure long-term use without cracking or deformation.
