Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: an integrated flange forging ball valve comprises a valve cavity 1, a sealing gasket 2 and a valve ball 3 which are arranged on the inner surface wall of the valve cavity 1, a valve rod 31 and a flow channel 32 are arranged on the valve ball 3, a position, close to the valve rod 31, of the inner surface wall of the flow channel 32 is provided with a relief groove 321, two side walls, close to two ends of the flow channel 32, in the relief groove 321 are hinged with gate plates 4, the two gate plates 4 extend out of the relief groove 321 to seal two ends of the flow channel 32, a driving rod 5 penetrates through the valve rod 31 and is movably connected with the valve rod 31 in a coaxial distribution mode, one end of the driving rod 5 penetrates through the relief groove 321 and is movably connected with the opposite sides of the two gate plates 4, the driving rod 5 controls the two gate plates 4 to rotate, the driving rod 5 is composed of an operating rod 51 and a traction block 52 rotatably connected with one end of the operating rod 51, the bottom of the, the top of the operating rod 51 is fixedly provided with a rotating handle 511, the operating rod 51 is matched with the valve rod 31 in a screwing mode, the traction block 52 is composed of a connecting block 521 and two connecting rods 522, the connecting block 521 is connected with the gate plate 4 in a hinged mode through the two connecting rods 522, after the driving rod 5 moves towards the direction of the gate plate 4, the two gate plates 4 block two opening portions of the flow channel 32, at the moment, the valve rod 31 is rotated, and the phenomenon that the sealing gasket 2 is damaged by combining hard impurities at two ends of the flow channel 32 cannot occur.
Specifically, as shown in fig. 2 and 3, opposite sides of the two gate plates 4 are spherical, the gate plates 4 form a complete sphere after blocking the flow passage 32, and the whole valve sphere 3 is sealed by combining the outer wall sealing gasket 2 of the gate plates 4, so that the sealing performance is good.
