Detailed Description

The utility model will be further described with reference to the drawings and embodiments.

Referring to fig. 1, fig. 2 and fig. 3 in combination, fig. 1 is a schematic structural view of a preferred embodiment of a multi-layer sealing structure of a welded ball valve according to the present utility model; FIG. 2 is a schematic view of the internal structure of the valve body shown in FIG. 1; fig. 3 is a schematic view of the intermediate filter cartridge of fig. 1. The utility model provides a multilayer seal structure of welding ball valve, includes valve body 1, and carousel 3 is installed in the upper surface rotation of valve body 1, and interior ball 2 is installed through carousel 3 rotation to the inside of valve body 1, and the both sides of valve body 1 all are fixed with both sides pipeline 4, and the outer wall of two both sides pipelines 4 all is fixed with the ring flange, and one of them both sides pipeline 4 is through ring flange fixedly connected with connecting pipe 5, all is fixed with first sealing rubber 6 on the ring flange of connecting pipe 5 and both sides pipeline 4, and the internally mounted of connecting pipe 5 has middle filter core 8.
