TECHNICAL FIELD
[0001] The utility model belongs to the technical field of ball valve, especially relates to a soft sealing high pressure ball valve. BACKGROUND
[0002] The soft sealing high pressure ball valve is widely used in metallurgy and other fields, and is used for controlling the flow of various fluid media and ensuring the safe operation of the pipeline system. This valve can generally withstand high pressure, has good sealing performance, flow regulation performance and corrosion resistance.
[0003] During use, the soft sealing high pressure ball valve used in the metallurgical field contains many impurity particles in the input high pressure and high temperature gas. These impurity particles are easy to be adsorbed on the inner wall of the ball valve, which reduces the use performance of the ball valve. Long-term accumulation of impurities can easily cause blockage of the internal pipeline of the ball valve, affecting the flowability of the internal gas, and thus affecting the flow regulation performance of the ball valve.
[0004] Secondly, the fluid medium in the metallurgical production often contains solid particles or impurities. These solid particles may enter the valve along with the fluid and accumulate on the valve core or valve seat, causing the valve to fail to normally open and close, and even completely blocking the pipeline, damaging the ball valve and affecting the production efficiency.
[0005] In summary, when designing and selecting the soft sealing high pressure ball valve used in the metallurgical field, an anti-blocking mechanism such as a self-cleaning structure or a self-cleaning design is often considered to be added to ensure the normal operation of the valve, reduce the failure rate and maintenance cost. Therefore, it is hoped to develop a new type of high pressure ball valve to solve the above problems. INVENTION CONTENTS
