볼 밸브의 작동 원리 및 특성
볼 밸브의 개폐 요소는 볼입니다., driven by the valve stem and rotating 90° around the valve’s axis to open or close. 유체 조절 및 제어에도 사용할 수 있습니다., primarily for cutting off, distributing, 파이프라인의 미디어 흐름 방향 변경. 밀봉이 잘 되는 것이 특징입니다, 편리한 조작, 신속한 개폐, 간단한 구조, 작은 크기, 낮은 저항, 그리고 가벼운 무게.
볼 밸브 작동 원리
1. Rotate the ball 90 degrees to the left via the valve stem to fully open the valve.
2. Rotate the ball 90 degrees to the right via the valve stem to fully close the valve.
Ball Valve Structure and Principle
1. A ball valve consists of a valve body, 밸브 스템, sealing seat, and ball.
2. The ball core of the ball valve is circular, and the opening can be adjusted via an analog signal, achieving precise regulation.
3. Reliable sealing; using PTFE seals achieves zero leakage, suitable for gas and vacuum systems.
4. High temperature resistance; using PPL seals or metal hard seals, it can be used normally in some high-temperature gases or liquids.
5. Simple structure; the seal can be freely disassembled and the sealing material replaced, making it convenient to use.
6. Long service life; under normal operating conditions, frequent operation requires no seal replacement and can withstand 100,000 consecutive cycles.
7. Wide applicability; suitable for water, 증기, 가스, 천연가스, 액화 가스, and other fields, applicable to high vacuum systems and high pressures.
8. Due to the wiping effect during the opening and closing process, ball valves can be used in media containing suspended solid particles.
9. Full-bore structure; low fluid resistance, large flow rate, and no flow loss. 10. Fast opening and closing speed: opening and closing only requires a 90-degree rotation, with the fastest opening time being 1 second.
