I. Introduction to QY347F oxygen special ball valve
QY347F oxygen special ball valve adopts high-quality materials, advanced structure, special technology and detection methods, which makes this type of ball valve have the advantages of rapid opening and closing, flexible, reliable sealing, compact structure and extremely small flow resistance compared with the copper globe valve used by the original metallurgical enterprise. . According to the particularity of oxygen transportation, the ball valve is designed with anti-static and fire-resistant structure, and each component is strictly degreased during assembly. The valve body and other parts are selected from high quality stainless steel and subjected to pickling, passivation, inspection and test. High pressure sealing test is performed with pure tap water without any grease, and 0.6Mpa gas is used for leak test. The valve should be leak-free; This type of ball valve not only operates quickly and easily, has small flow resistance, is safe and reliable, but also has a long service life (small sealing pair flushing).
设计特色 Second, QY347F oxygen special ball valve design features
1. Fire and fire resistance: The material of the main components is copper alloy, which is a non-combustible material. It will not produce sparks even if it collides with solid particles in high-speed airflow. Therefore, this valve has the best fire and flame resistance performance;
2. Safe and reliable: The valve is equipped with dust-proof, water-proof and oil-proof devices. All the valve parts that come into contact with oxygen have undergone strict degreasing and oil-free measures before assembly. The filling material is polytetrafluoroethylene to ensure safety during use. reliable;
3. The flange ends are provided with conductive screw holes to prevent static electricity.
