Problems solved by technology

[0003] Now polyethylene valves are more and more used in drinking water pipelines due to the advantages of life and price. At present, the existing problems are that the structure is complex, the sealing ring has many matching parts, the process of sub-parts requires high precision, and the cumulative error is large. The difference between each valve is large and the quality is not stable enough
At present, the com...

Abstract

The invention is suitable for the technical field of ball valves, and provides a novel PE sealing ball valve. The novel PE sealing ball valve comprises a valve body, a variable diameter, a valve rod and a valve element; the valve body and the variable diameter are in hot melt welding; the valve element is positioned in accommodating space formed by combining the variable diameter with the valve body; a fixed hole is formed in the valve element; a groove is formed in the fixed hole; multiple first sealing rings are arranged between the valve rod and the valve body; multiple second sealing ringsare arranged between the valve element and the variable diameter; the valve rod is provided with moving space and a limiting groove; a moving rod is arranged in the moving space; matched thread holesare formed in the upper ends of the moving rod and the valve rod; the lower end of the moving rod is a spherical end; a fixed block is arranged in the limiting groove; an elastic piece is arranged between the fixed block and the valve rod; the diameter of the spherical end is larger than the length of the limiting groove; and the fixed block is matched with the groove. The novel PE sealing ball valve can be effectively opened and closed, reduces the damage of the sealing rings, guarantees the tightness thereof, and meanwhile, can effectively adjust the position of the valve rod to prevent random opening and closing thereof.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a novel PE sealed ball valve. Background technique [0002] In the 1970s, the United States Swan Luosim company first developed and produced polyethylene (PE) valves, which were widely used in polyethylene (PE) gas pipeline systems. In the mid-1990s, polyethylene (PE) gas pipelines were widely used in large cities and towns in my country. People gradually realized the superiority of polyethylene (PE) valves in terms of performance and price, and gradually began to use polyethylene (PE) valves to replace them. Metal valves. [0003] Now polyethylene valves are more and more used in drinking water pipelines due to the advantages of life and price. The existing problems are that the structure is complex, the sealing ring has many matching parts, the process of sub-parts requires high precision, and the cumulative error is large. As a result, the difference between each valve is...
