Fluorine-lined ball valve Yongjia fluorine-lined valve manufacturer Overview of fluorine-lined ball valve , use the ball to rotate 90o around the axis of the valve stem to achieve the purpose of opening and closing. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. The ball valve designed with V-shaped opening also has a good flow adjustment function. The ball valve is not only simple in structure and good in sealing performance, but also small in volume, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and easy to open and close quickly within a certain nominal diameter range. One of the fastest growing valve varieties in the past ten years. Especially in developed industrial countries such as the United States, Japan, Germany, France, Italy, Spain, and the United Kingdom, the use of ball valves is very extensive, and the variety and quantity of ball valves are still expanding. Its reliability and other performance indicators have reached a high level, and it has partially replaced gate valve
s, globe valve
s and throttle valves. With the advancement of ball valve technology, it will be widely used in oil and gas pipelines, oil refining crackers and the nuclear industry in the foreseeable short term. In addition, ball valves will also become one of the dominant valve types in the fields of large and medium caliber, medium and low pressures in other industries. The ball valve is a kind of valve that came out in the 1950s. In half a century, the ball valve has developed into a major valve type. The ball valve is mainly used to cut off or connect the medium, and can also be used for the regulation and control of the fluid. The V-shaped ball valve can carry out relatively accurate flow regulation and control, while the three-way ball valve is used to distribute the medium and change the flow direction of the medium. Yongjia Yate fluorine-lined ball valve has the following advantages: 1. Yongjia Yate fluorine-lined ball valve has low fluid resistance, and the ball valve is the one with the smallest fluid resistance among all valves. Even the reduced diameter ball valve, its fluid resistance is quite small. 2. Yongjia Yate fluorine-lined ball valve switches on and off quickly and conveniently. As long as the valve stem rotates 90°, the ball valve completes the full opening or full closing action, and it is easy to realize rapid opening and closing. 3. The ball valve has good sealing performance. The sealing ring of the ball valve seat is generally made of elastic materials such as PTFE, which is easy to ensure the sealing, and the sealing force of the ball valve increases with the increase of the medium pressure. 4. Yongjia Yate fluorine-lined ball valve stem has reliable sealing. When the ball valve is opened and closed, the valve stem only rotates, so the packing seal of the valve stem is not easy to be damaged, and the sealing force of the reverse seal of the valve stem increases with the increase of the medium pressure. 5. The opening and closing of the ball valve only rotates 90°, so it is easy to realize automatic control and remote control. The ball valve can be equipped with pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage devices or electro-hydraulic linkage devices. Fluorine-lined ball valve Yongjia fluorine-lined valve fluorine-lined ball valve installation instructions: 1. The front and rear pipelines of Yongjia Yate fluorine-lined ball valve are ready. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to bear the weight of the ball valve, otherwise the pipeline must be provided with proper support. 2. Purge the pipelines before and after the valve to remove oil, welding slag and all other impurities in the pipeline. 3. Check the mark of the ball valve to find out that the ball valve is intact. Open and close the valve several times to verify that it is working properly. 4. Remove the protective pieces on the connecting flanges at both ends of the ball valve. 5. Check the valve hole to remove possible dirt, and then clean the valve hole. Even small particles of foreign matter between the seat and the ball can damage the seat sealing surface. 6. Install the valve on the pipeline. Either end of the valve can be installed on the upstream end. The handle-actuated valve can be installed anywhere on the pipeline. However, ball valves with gearboxes or pneumatic drives should be installed upright, that is, on a horizontal pipeline with the drive above the pipeline. 7. Install a gasket between the valve flange and the pipeline flange according to the pipeline design requirements. 8. The bolts on the flange should be tightened symmetrically, sequentially and evenly. 9. Connect the pneumatic pipeline (when using the pneumatic driver). 10. Yongjia Yate fluorine-lined ball valve operates the driver to open and close the ball valve several times, and it should be flexible without stagnation, which proves that it works normally. 11. Check the sealing performance of the flange joint surface between the pipeline and the ball valve according to the pipeline design requirements.
Getting doesn't have to be expensive, time-consuming, or difficult. It all comes down to the right method and a types of industrial valves valve application in place.
