Abstract

The utility model discloses a heat and electric insulation protective sleeve which is in a cylindrical tubular shape; the sleeve comprises a glass fiber woven body; the number of wefts per decimeter of the glass fiber woven body is two to nine; a silica gel coating is coated on the outer circumferential surface of the glass fiber woven body; the sleeve not only has good heat insulation, insulating and reinforcing protective performance, but also has good extensibility; when the diameter of a sleeved object is suddenly and significantly changed, the sleeve can be also tightly sleeved on the object; and the heat and electric insulation protective sleeve can be widely applied to cable and pipeline connection.

Description

A kind of heat insulation, electrical insulation protective casing

Technical field

The utility model relates to a kind of heat insulation, electrical insulation protective casing.

Background technique

In being connected of object and object, like the joint between cable and the cable, the joint between the pipeline diameter usually can occur suddenly and the situation of notable change; At this moment when its outside sheathed protective casing, just be prone to sheathed untight situation; At present, generally use heat-shrink tube for having the object that is connected unexpected and vary in diameter significantly, heat-shrink tube can be when temperature raises reduced; But it does not have glass fiber component; Reinforcement protection is indifferent, although existing protective casing has the performance of good insulation, insulation and reinforcing insulation, its expansion service is relatively poor; Can not be applied in unexpected and significant vary in diameter, its application receives great restriction.

Summary of the invention

The purpose of the utility model provides a kind of heat insulation, electrical insulation protective casing with good expansion service.

For achieving the above object, the technological scheme that the utility model adopts is:

A kind of heat insulation, electrical insulation protective casing, the cylindrical tubulose of said sleeve pipe, said sleeve pipe comprises fiberglass braided body, the per minute rice parallel of said fiberglass braided body is the 2-9 root, is coated with silica-gel coating on the outer peripheral surface of said fiberglass braided body.

Because the utilization of technique scheme; The utility model compared with prior art has advantage: the utility model selects per minute rice parallel numeral system to become fiber glass body according to the diameter of sleeve pipe with weaving manner; And on the outer peripheral surface of fiberglass braided body, be coated with silica-gel coating; This is heat insulation, the electrical insulation protective casing not only has good insulation, insulation, reinforcement protection performance; Can be heat insulation to being undertaken by sheathed object, electrical insulation and reinforcement protection, and have good extensibility, sheathed object have unexpected and during significant vary in diameter; Also can closely be set on this object, can be widely used in cable connection, pipeline connection etc. and connect.

Description of drawings

Accompanying drawing 1 is the internal structure schematic representation of the sleeve pipe of the utility model;

Accompanying drawing 2 is the cross-sectional schematic of the sleeve pipe of the utility model;

Accompanying drawing 3 is that the sleeve pipe of the utility model is in user mode cross-sectional schematic for the moment;

Accompanying drawing 4 is the schematic representation of sleeve pipe when user mode two of the utility model;

Accompanying drawing 5 is the schematic representation of sleeve pipe when user mode three of the utility model;

Wherein: the 1-sleeve pipe; The fiberglass braided body of 2-; The 3-silica-gel coating; The 4-object; The 5-weld; 6, the 7-cable; 8-cable joint.

Embodiment

Come further to set forth the structure of the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1-2; A kind of heat insulation, electrical insulation protective casing 1; Sleeve pipe 1 cylindrical tubulose, this sleeve pipe 1 comprises fiberglass braided body 2, on the outer peripheral surface of the good fiberglass braided body 2 of braiding, also is coated with silica-gel coating 3; Diameter according to sleeve pipe 1 is different with weaving manner, and it is between the 2-9 root that fiberglass braided body 2 adopts per minute rice parallel.If the diameter of sleeve pipe 1 is bigger, then per minute rice parallel can adopt less radical, can guarantee that like this sleeve pipe 1 has expansivity preferably, and certainly, the per minute rice parallel number of employing also will be confirmed according to weaving manner.On the outer peripheral surface of fiberglass braided body 2, be coated with silica-gel coating 3; Silica-gel coating 3 good temperature resistance ability, insulating property make sleeve pipe 1 integral body have the performance of heat insulation and electrical insulation, and the ductility preferably of silica-gel coating 3 more makes whole sleeve pipe 1 have good extensibility.Measure through routine inspection, according to like the sleeve pipe that obtains 1 of upper type when 100% elongation, Young's modulus is in the 0.5-3.5 MPa, tearing modulus is at thousand Ns of 5-45/rice.

Be depicted as several user mode schematic representation of this sleeve pipe 1 referring to Fig. 3-5; Among Fig. 3; Two

cables

6 and 7 adopt welding to be connected, and weld 5 with respect to the diameter of

cable

6 and 7 obvious variation has taken place, when sleeve pipe 1 is set in this weld 5; Because its good extensibility can closely be packaged on this weld 5; Fig. 4 is the schematic representation that this sleeve pipe 1 is connected the cable joint, and Fig. 5 has reflected the situation that the outside of sleeve pipe 1 changes along with the vary in diameter that is set in its inner object.

In sum; Heat insulation, the electrical insulation protective casing of the utility model not only have good insulation, insulation, reinforcement protection performance; Can be heat insulation to being undertaken by sheathed object, electrical insulation and reinforcement protection, and have good extensibility, sheathed object have unexpected and during significant vary in diameter; Also can closely be set on this object, can be widely used in cable connection, pipeline connection etc. and connect.

The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.

Claims

1. heat insulation, electrical insulation protective casing; The cylindrical tubulose of said sleeve pipe; It is characterized in that: said sleeve pipe comprises fiberglass braided body, and the per minute rice parallel of said fiberglass braided body is the 2-9 root, is coated with silica-gel coating on the outer peripheral surface of said fiberglass braided body.
