A sleeve shell sticking edge is extended from any one sleeve shell docking edge of the sleeve shell and is adhesively bonded to the sleeve shell docking edge on the opposite side of the sleeve shell through a fastener. The side skirt body is an annular structure, and the outer ring edges of the two side skirt bodies are sewn on the circumferences of the axial end faces of the sleeve shell body. The side skirt body is provided with a side skirt body docking edge along the generatrix direction where the sleeve shell docking edge is opened. A side skirt body sticking edge is extended from any one side skirt body docking edge of the side skirt body and is adhesively bonded to the side skirt body docking edge on the opposite side of the side skirt body through a fastener. The inner ring edge of the side skirt body is coaxially sewn outwards to form a side sleeve body. The side sleeve body is a cylindrical tube structure with a side sleeve body docking edge corresponding to the sleeve shell docking edge. A side sleeve body sticking edge is extended from any one side sleeve body docking edge of the side sleeve body and is adhesively bonded to the side sleeve body docking edge on the opposite side of the side sleeve body through a fastener. One or more tightening adhesive tapes are axially arranged on the outer circumference of the side sleeve body. The tightening adhesive tape is wound around the side sleeve body docking edge through a fastener and is adhesively bonded to the sticking section on the outer circumference of the side sleeve body, or the tightening adhesive tape is wound around the outer circumference of the side sleeve body for more than one circle and is adhesively bonded to the sticking section on the outer circumference of the tightening adhesive tape through a fastener.

[0005] Counterweight edges or counterweight strips are sewn inside the two sides of the sleeve shell docking edge.

[0006] The sleeve shell docking edge is arranged facing directly downwards.

[0007] One or more outer fastener rings are also included. One or more outer fastener rings are axially distributed through back glue and are wound and fixed on the valve connecting pipe. The outer circumference of the outer fastener ring is adhesively bonded to the inner fastener ring on the inner wall of the side sleeve body.

[0008] The inner fastener ring is axially corresponding or offset with the tightening adhesive tape on the side sleeve body.

[0009] The sleeve shell, the side skirt body and the main sleeve body are of a multi-layer waterproof, heat-insulating and heat-preserving cloth layer structure.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The docking edges of the housing, side skirt, and main housing are all opened downward for downward installation, effectively preventing external water from entering.

[0012] 2. The docking edge of the housing is internally provided with a counterweight edge or strip, effectively preventing rotation and displacement after downward installation, and always ensuring downward waterproofing.

[0013] 3. The docking edges of the housing, side skirt, and main housing are all connected with Velcro edges for docking, which is convenient for installation and disassembly and has a firm connection.

[0014] 4. The main housing is tightened with a tightening adhesive tape to prevent water from entering from the side, and has good sealing and waterproof performance; combined with the cooperation of internal and external Velcro rings, the bonding firmness and sealing performance between the main housing and the valve connection pipe are further improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following is further described with reference to the accompanying drawings.

[0022] Figures 1-4Embodiment 1 shown: A waterproof valve sleeve, comprising a sleeve shell 3, a side skirt 6 and a side sleeve 9. The sleeve shell 3 is a cylindrical tube structure with a sleeve shell docking edge 4 opened along the generatrix. One sleeve shell docking edge 4 of the sleeve shell 3 extends out a sleeve shell fastening edge 5, and the sleeve shell is adhesively bonded to the opposite sleeve shell docking edge through the fastening. The side skirt 6 is an annular structure, and the outer ring seams of the two side skirts 6 are sewn on the circumferential edge of the axial end face of the sleeve body 3. The side skirt 6 is provided with a side skirt docking edge 7 along the generatrix direction where the sleeve shell is provided with the sleeve shell docking edge. One side skirt docking edge 7 of the side skirt 6 extends out a side skirt fastening edge 8, and the side skirt is adhesively bonded to the opposite side skirt docking edge through the fastening. The inner ring edge of the side skirt 6 is coaxially sewn outwards to form the side sleeve 9. The side sleeve 9 is a cylindrical tube structure provided with a side sleeve docking edge corresponding to the sleeve shell docking edge. One side sleeve docking edge 10 of the side sleeve 9 is connected to a side sleeve fastening edge 11, and the side sleeve is adhesively bonded to the opposite side sleeve docking edge through the fastening. One or more tightening adhesive tapes 12 are axially arranged on the outer periphery of the side sleeve 9, and the tightening adhesive tape 12 winds around the outer periphery of the side sleeve 9 and is adhesively bonded to the fastening section on the outer periphery of the tightening adhesive tape.
