Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Wherein, 1, a sleeve; 2. an inner baffle; 3. an outer baffle; 4. a filling bag; 5. making a gasket by using inner steel; 6. making a gasket by using external steel; 7. a nut; 8. a wire rod part; 9. and (5) tightening the nut.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the specific drawings.
Examples
The utility model provides an interim shutoff system of sleeve pipe, as shown in fig. 1, sleeve pipe 1's inside is equipped with interior baffle 2, sleeve pipe 1's outer end is equipped with outer baffle 3, interior baffle 2 and outer baffle 3 are wooden circular baffle, the diameter of interior baffle 2 slightly is less than sleeve pipe 1's internal diameter, the diameter of outer baffle 3 is greater than sleeve pipe 1's external diameter, sleeve pipe 1's inside is located and is equipped with filler package 4 between interior baffle 2 and the outer baffle 3, the inside medial extremity that is located interior baffle 2 of sleeve pipe 1 is equipped with interior steel gasket 5, the outside end of outer baffle 3 is equipped with outer steel gasket 6, the long screw is equipped with nut 7 and lead screw portion 8, lead screw portion 8 passes interior steel gasket 5 from sleeve pipe 1's inside in proper order, interior baffle 2, filler package 4, outer baffle 3, outer steel gasket 6 to sleeve pipe 1's outside, and tighten up through fastening nut 9. The filling bag 4 comprises a plastic outer bag filled with loess.
In the embodiment, the fastening nut 9 is used for tightening the cavity in the compression sleeve, the filler bag 4 is extruded in each gap by using the principle of 'pressure diffusion in a closed container', the temporary plugging purpose is achieved, and when the device is detached, only the fastening nut 9 needs to be loosened and each part needs to be taken out.
