AI Technical Summary

Problems solved by technology

The nominal pressure of the high-pressure floating ball valve reaches 70MPA. According to the valve test standard, a high-pressure shell test and a high-pressure sealing test are required. The test pressure must reach 150MPA and 77MPA respectively. Under such a high pressure, the valve needs to withstand the pressure while ensuring zero leakage of the valve. , there are very high requirements on the sealing performance of the valve, and it is impossible for ordinary floating ball valves to meet such high requirements.

Abstract

The invention relates to a rapid installation type high pressure floating ball valve which comprises a valve body (1), two valve decks (2) connected to the two sides of the valve body (1) through fastening pieces, and valve seats (3), a sphere (4), a valve rod (5) and a handle (6) which are located in the valve body (1), the handle (6) is connected to the valve rod (5), the valve rod (5) is connected to the sphere (4) which is located in the valve seats (3), a micro serrated butt joint face structure is adopted between the valve body (1) and the valve decks (2), at the same time, a neck seal structure is designed to be matched with the micro serrated butt joint face structure, the sealing performance of the valve is improved, valve testing standards are met, and zero leakage is guaranteed.

Description

technical field [0001] The invention relates to a fast-installed high-pressure floating ball valve. Background technique [0002] The ball valve is a kind of starting part, which is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid. High-pressure floating ball valves are suitable for general industrial use, and are suitable for chemical, petroleum, natural gas, metallurgy and other industries and long-distance natural gas pipelines with hydrogen sulfide-containing media, many impurities, and severe corrosion. The nominal pressure of the high-pressure floating ball valve reaches 70MPA. According to the valve test standard, a high-pressure shell test and a high-pressure sealing test are required. The test pressure must reach 150MPA and 77MPA respectively. Under such a high pressure, the valve needs to withstand the pressure while ensuring zero leakage of the valve. , There are very high requirements ...
