Abstract

The invention discloses a ball valve. The ball valve comprises a valve base, a valve cover, a valve element and a valve rod; the valve element is spherical; extension lines of the valve rod and a positioning rod do not pass through the ball center; the valve element is rotated around the positioning rod in a valve cavity; the valve element is in release contact with an outlet; a channel is connected with an inlet and the outlet; the positioning rod is matched with a positioning hole at the bottom of the valve cavity; the valve cavity is positioned in the valve base, and is connected with the outlet and the inlet; the valve base is matched with the valve cover; a stud of the valve cover is matched with a pressing nut; and the valve rod extends outside the valve cover and the pressing nut. The ball valve is simple in structure, not easy to leak, high in reliability and capable of frequently operating.

Description

technical field [0001] The invention relates to a ball valve. Background technique [0002] At present, the known ball valves are prone to wear and tear due to long-term frequent operation. As fluids are widely used in society, valves for controlling fluid delivery are widely used. After years of development, the types of valves have become various. At the same time The problem of valve leakage has also become more and more difficult. The distance between the existing valve body and the valve outlet is a fixed value. Long-term operation is easy to wear and cause leakage. After leakage, only the valve core or valve can be replaced. There are complex and durable valves on the market, but their high price And the complex structure makes it impossible to be widely used in life. [0003] Existing Chinese patents such as: Swing ball valve (1884881), discloses a swing ball valve, including a valve body, a valve seat, a ball, a valve stem, and a valve cover; The inner cavity, the...
