Overview of electric three-piece ball valve: The electric three-piece ball valve (electric internal thread ball valve) is assembled from three parts: the left and right valve casings and the middle valve body. Four longer bolts traverse the three-section valve casing, and tightly clamp the middle valve body from both ends. The biggest advantage of the electric three-piece ball valve is that it is particularly easy to disassemble. When the valve fails or needs to be repaired, it is not necessary to disassemble the thread of the pipeline, but the four-piece ball valve can be taken off directly, and the body part can be taken out. It not only reduces the probability of failure, but also improves the working efficiency. It is especially suitable for working conditions with small mechanical volume and narrow space. Electric three-piece ball valve principle: The three-piece electric ball valve has reliable sealing performance and high pressure. Its action principle is to drive the valve core to rotate 90 degrees through the power supply voltage of the electric actuator to open and cut off the medium. It can be designed as The two-position switch control of the medium can also realize the proportional adjustment of the medium flow, pressure, temperature and other parameters in the pipeline. Electric three-piece ball valve standard specification: Test inspection: API598, EN12266 Threaded end: ASME B1.20, BS21 DIN2999/259, BSP ISO7/1, ISO228/1 JIS B 0203 Butt weld ends: ASME B16025 Sleeve Welding Ends: ASME B16.11 Flange connection: ASME B16.5 DIN2542~2545 JIS B2238 Classification and difference of electric chip ball valve: The movable one-piece ball valve is one-piece, and the ball is fixed by a plug, which facilitates its maintenance and can be used in working conditions that require quick opening and quick closing. The electric two-piece ball valve is composed of two parts, which are fixed by two pieces of valve bodies clamping the ball. The maintenance is relatively complicated. The tightness of the middle screw is related to whether there will be air leakage, The electric three-piece ball valve is similar to the two-piece ball valve. It consists of left and right end covers and a middle valve body, and then enters the sheep clamp with necks on both sides. Its pressure is higher than that of the other two types.
