Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1-2, a valve body with good sealing performance, wherein a connecting pipe 3 is internally connected at the left end and the right end of the valve body, the connecting pipe 3 is composed of an inner pipe 31 inserted into the valve body 1 and an annular connecting plate 32 fixedly connected on the outer wall of the inner pipe 31 in a surrounding manner, the left end and the right end of the valve body 1 are fixedly connected with an extending section 6 vertically protruding out of the valve body 1, a first sealing gasket 4 is arranged between the annular connecting plate 32 and the extending section 6, the outer side ends of the annular connecting plate 32 and the extending section 6 are movably connected with an outer cover body, the outer cover body is composed of a straight cylinder 21 and a plug 22 at the end of the straight cylinder 21, the plug 22 can be sleeved on the connecting pipe 3, the inner wall of the plug 22 is fixedly connected with a second sealing gasket 5, and the second sealing gasket 5 is attached to the connecting pipe 3; the outer wall of the outer cover body is fixedly connected with a connecting arm 7, a flange 8 is arranged on the valve body 1, and the connecting arm 7 is connected to the flange 8 in a screwing mode.
The width of the annular connecting plate 32 is equal to the inner diameter of the outer cover body 2, and the outer end of the annular connecting plate 32 and the outer end of the plug 22 are located on the same horizontal line, so that when the outer cover body 2 is sleeved on the valve body 1, the outer cover body 2 can be tightly attached to the annular connecting plate 32 and the outer end of the extending section 6 at the tail end of the valve body 1.
Because the inner end of the inner pipe 31 is inserted into the valve body 1, the outer end of the inner pipe 31 protrudes out of the plug 22 at the outer end of the outer cover body 2, the pipeline is connected with the outer end opening of the inner pipe 31 in a sealing manner, liquid directly flows into the valve body 1 from the inner pipe 31, the inner pipe 31 isolates the first sealing gasket 4 from the internal environment of the valve body 1, and the first sealing gasket 4 is prevented from being corroded, aged and damaged.
