Examples: referring to fig. 1-5, the present utility model provides a technical solution: a sanitary valve structure easy to assemble and disassemble is mainly used for solving the problems that the use of the sanitary valve is affected due to poor sealing effect of the joint of the conventional sanitary valve. The specific scheme is as follows: the valve comprises a valve body 1 and connecting pipe fittings 4 arranged on two sides of the valve body 1, wherein the valve body 1 is a sanitary valve body. The connecting pipe 4 is connected with the valve body 1.

Referring to fig. 1, 2 and 3, an adapter sleeve 2 is arranged between a valve body 1 and a connecting pipe fitting 4, an annular inner baffle 21 is arranged in the adapter sleeve 2, and the annular inner baffle 21 and the adapter sleeve 2 are integrally processed. Wherein, all be equipped with cavity flexible circle 3 at annular inner baffle 21 and valve body 1 and the relative tip of connecting tube 4, the material of cavity flexible circle 3 is flexible rubber, through the cavity flexible circle 3 of flexible material, resumes the elasticity, can further improve the leakproofness of valve body 1 and connecting tube 4 junction. Specifically, a U-shaped clamping groove 26 for clamping the hollow flexible ring 3 is formed in the annular inner baffle 21. The groove width of the U-shaped clamping groove 26 is smaller than the outer diameter of the hollow flexible ring 3, so that the hollow flexible ring 3 can be stably clamped inside the U-shaped clamping groove 26.

Further, two opposite ends of the adapter sleeve 2, the connecting pipe fitting 4 and the valve body 1 are respectively provided with a clamping groove 22, wherein the outer diameter of the clamping grooves 22 is larger than the inner diameter of the adapter sleeve 2. An inserting block 23 is annularly arranged on the inner side of the clamping groove 22, and the inserting block 23 and the adapter sleeve 2 are integrally processed.

Further, the valve body 1 and the opposite ends of the connecting pipe fitting 4 and the adapter sleeve 2 are respectively provided with an outer convex lapping plate 5, the outer diameter of the outer convex lapping plate 5 is larger than the outer diameter of the opposite ends of the valve body 1 and the connecting pipe fitting 4, and the outer convex lapping plate 5 and the corresponding opposite ends of the valve body 1 and the connecting pipe fitting 4 are integrally processed. The external diameter of the adapter sleeve 2 is larger than that of the outer convex lapping plate 5. The thickness of the outer convex lapping plate 5 is smaller than the depth of the clamping groove 22, and the outer convex lapping plate 5 is movably inserted into the clamping groove 22.

Further, the outer side of the convex lapping plate 5 is provided with annular inserting grooves 6 for movably inserting the inserting blocks 23, the inserting blocks 23 correspond to the inserting grooves 6 in number, and the inserting grooves 6 are through grooves. The adapter sleeve 2 can not rotate relative to the valve body 1 and the connecting pipe fitting 4 by inserting the plug block 23 into the plug groove 6.

In the embodiment, the valve body 1, the connecting pipe fitting 4 and the opposite end parts of the adapter sleeve 2 are respectively inserted with a limit screw sleeve 24 and a limit screw rod 25.
