Example one

As shown in fig. 3 to 4, the flexible cut-off device includes a sleeve assembly and a capsule, the sleeve assembly includes a barrel 10 and a cover 20, the barrel 10 of the sleeve assembly surrounds the capsule 30, and the cooperation of the barrel 10 and the cover 20 is used for fixing the capsule 30 of the flexible cut-off device. The barrel 10 includes a first fold 11 at the end of the barrel. The end of the capsule 30 comprises a flange 31, the flange 31 being parallel to the first fold 11 of the barrel. In practical application, when the flange 31 and the first bent portion 11 are close to each other, the flange 31 and the end of the first bent portion 11 may be flush with each other, but the flange is not suitable for protruding the end of the bent portion. The lid 20 includes a second fold 21 and a third fold 22 at the lid edge.

The first bent portion 11 of the cylindrical body 10 and the third bent portion 22 of the lid 20 are provided with notches which can mesh with each other. In practical application, the first bending part 11 of the cylinder body can be bent towards the inner direction of the cylinder body or towards the outer direction of the cylinder body; the second bending part and the third bending part of the cylinder cover can correspond to the cylinder cover. After the cylinder cover is meshed with the cylinder body through the tooth openings, the cylinder cover and the tooth openings of the cylinder body are on the same vertical plane; after the cover is pushed, at the visual angle as shown in fig. 3, the cover moves leftwards, the tooth openings of the cover and the cylinder are in different vertical planes, the tooth openings of the cover are close to the left, the tooth openings of the cylinder are close to the right, and then the cover is rotated, so that the tooth openings of the cover and the cylinder are overlapped on the transverse plane, and the capsule is fixed between the cover and the cylinder.

In the above embodiments, the operation principle of the cylinder and the cylinder cover which form the sleeve assembly is shown in fig. 5 to 7. The first bending part 11 of the cylinder 10 is provided with a first tooth 111 and a first tooth groove 112. The third bending part 22 of the cover 20 is provided with a third tooth 221 and a third tooth slot 222. The third teeth 221 of the cover are engageable with the first teeth slots 112 of the barrel, and the third teeth slots 222 of the cover are engageable with the first teeth 111 of the barrel. During the fixing process of the capsule body by the barrel assembly, the third teeth 221 of the barrel cover are firstly meshed with the first teeth grooves 112 of the barrel, and the third teeth grooves 222 of the barrel cover are firstly meshed with the first teeth 111 of the barrel.

Moreover, in the prior art, in the bolt fixing mode, when the caliber of the capsule is larger, the size of the cylinder is larger, the number of drilled holes is larger, the number of selected bolts is larger, the number of the selected bolts is larger, the labor hour consumed during assembly is longer, and the production cost is higher. The scheme of the invention does not need drilling and installing bolts, only needs the meshing of the cylinder cover and the tooth mouth of the cylinder body, and then pushes and rotates, and the quick installation mode can greatly save working hours. In addition, the mode of bolt fixing is adopted in the prior art, the larger the caliber of the bag body is, the larger the specification of the bolt is, the larger the drilling section of the first bending part is, and the larger the integral body type of the flexible cut-off device is. In this embodiment, the edge of the capsule may also be provided with a tooth mouth matched with the cylinder cover to increase the clamped surface of the capsule.

In the first embodiment, a gasket 50 is further provided in the sleeve assembly. The gasket 50 is built into the cover and can apply pre-pressure to the bladder to reduce friction. The gasket can reduce the resistance of the cylinder cover during rotation on one hand and can also reduce the abrasion of the surface of the capsule on the other hand. In addition, the capsule is clamped by the barrel body and the barrel cover, tolerance requirements are set on the first bending part of the barrel body, the second bending part of the barrel cover and the third bending part of the barrel cover, the better tolerance control is, the easier assembly process is, and the better effect of clamping the capsule is. However, due to the limitation of the process conditions, for example, the welding process is adopted for the bent parts of the cylinder body and the cylinder cover, the machining precision cannot completely meet the requirement, and the assembly is affected. Compared with the bent parts, the process of the gasket is much easier to control, so that the problem of insufficient precision control of the bent parts can be adjusted or compensated by controlling the tolerance of the gasket.

Example two

As shown in fig. 8, on the basis of the first embodiment, the surface of the flange 31 of the capsule body is provided with a groove, and the first bending part 11 of the cylinder body is correspondingly provided with a convex hull; or, alternatively, the surface of the flanging of the bag body is provided with a convex hull, and the first bending part of the cylinder body is correspondingly provided with a groove.

Common flexible cut-off devices have two-point deformation, three-point deformation or four-point deformation. The two-point deformation requires that the diameter of the cylinder in the sleeve assembly is larger than that of the capsule because the size of the cross section of the binding surface of the capsule after deformation is larger than that of the diameter of the capsule before deformation, so that the integral size of the device is too large and is gradually eliminated. The technology of present mainstream makes the utricule produce three point and warp, but when the utricule warp the laminating and close the passageway, warp the node department and be the laminating that the arc was bent the department can not be complete, must have the gap and the leakproofness is not good enough. This embodiment radially sets up the arch in the middle part of utricule, and bellied hardness is less than the hardness of utricule, and the utricule is compared to the arch and is out of shape more easily, consequently warp the laminating in-process at the utricule of flexible cut-off equipment, and the deflection is bigger when protruding by the extrusion to can fill the slit, with the sealed effect when providing flexible cut-off equipment and closing the passageway. In addition, the flexible cut-off device is used in a drainage system, and a sealing ring 60 is arranged at the joint of the flexible cut-off device and a downstream pipeline, so that water leakage at the joint can be prevented.

Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications, re-combinations or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
