Abstract
The invention relates to an insulating tube, in particular to a medium/low-pressure open insulating protective sleeve. The medium/low-pressure open insulating protective sleeve is characterized by comprising a tube body (1) and clamping buckle devices (2). Openings at the two ends of the tube body (1) are provided with the clamping buckle devices (2); each clamping buckle device (2) consists of an arc edge (3), a clamping hook (4) and a clamping slot (5), wherein the clamping hook (4) is arranged at one end of the arc edge (3); the clamping slot (5) is arranged at the other end of the arc edge (3); the clamping hook (4) and the clamping slot (5) are in clearance fit; and the arc edge (3) and the sleeve body (1) are in interference fit. The medium/low-pressure insulating protective sleeve is a clamping buckle type insulating line protective sleeve of an open mounting structure, overcomes the defect of the complex mounting of conventional insulating protective products, and is convenient and quick in mounting and in no need of hot work and any free end.
Description
One, technical field:
The present invention relates to a kind of insulated tube, be specifically related to a kind of in, low-pressure open insulation protection sleeve pipe.
Two, background technology
Present protection place at insulated circuit; insulating tape, mesolow insulate heat contraction bands or pyrocondensation insulating protection sleeve pipe etc. are adopted in the insulation protection of transmission line usually, at a lot of occasion construction inconvenience, the especially insulating protections of high-altitude bare wire; use the present invention, quick and easy for installation.
Three, summary of the invention:
Technical purpose
The purpose of this invention is to provide a kind of in, low-pressure open insulation protection sleeve pipe, the present invention is safe and reliable insulation protection product, for the safe operation of electric power system provides favourable guarantee, has good economic benefits and social benefit.
Technical scheme
The present invention has following technical scheme to finish: in a kind of, low-pressure open insulation protection sleeve pipe, it is characterized in that comprising body and bayonet unit, bayonet unit is located at described body both ends open place, described bayonet unit is made up of circular arc limit, grab and draw-in groove, described grab is located at an end on circular arc limit, described draw-in groove is located at the other end on circular arc limit, and grab and draw-in groove form matched in clearance; Described circular arc limit and body form interference fit.
As a kind of optimal way, described grab is a semi-circular projection, and described draw-in groove is a semicircle groove, grab and draw-in groove cooperatively interact, and form matched in clearance, and the draw-in groove inboard is provided with insulating cement, grab and draw-in groove are combined closely, play the effect of sealing and insulation.
As another kind of optimal way, described grab is square projection, and described draw-in groove is a square groove.
As another kind of optimal way, described body can individual layer or double-deck material contracting with heat constitute, the heating body is inserted in lead during use, cooling makes body shrink, and forms insulating outer layer.
During use body is inserted in protected lead from opening part, directly with the bayonet unit fastening, scribbles insulating cement in the draw-in groove then, the chucking back is installed forms an airtight insulation protection pipe.
The material contracting with heat principle: because cross-linking radiation changes polyolefinic molecular structure, this variation makes polyolefin have memory effect under certain condition.Heat-shrinkable tube utilizes the principle of this memory effect just, behind the heat-shrinkable tube semi-finished product cross-linking radiation, with behind its expansion cooling and shaping, is exactly finished product after the heating.In use, the heating back is because memory effect retracts to the preceding state of expansion again.
Beneficial effect
1, the present invention is a kind of buckle-type insulated circuit protection tube, is open mounting structure, has overcome the defective of the installation complexity of insulating protection product in the past, and is quick and easy for installation, do not need to get angry, and do not need free end.
2, owing to scribble insulating cement in the draw-in groove, this glue can so that bayonet unit in use, sealed insulation, thereby the present invention is safe and reliable.
3, the present invention is because body can be for the good material contracting with heat of insulation property, so have good insulation.
4, the present invention is applicable to the transmission of electricity bare wire, crosses obstacles such as setting, pass through bridge, can carry out insulation protection .. to the lead of long distance
Principle: because cross-linking radiation changes polyolefinic molecular structure, this variation makes polyolefin have memory effect under certain condition.Heat-shrinkable tube utilizes the principle of this memory effect just, behind the heat-shrinkable tube semi-finished product cross-linking radiation, with behind its expansion cooling and shaping, is exactly finished product after the heating.In use, the heating back is because memory effect retracts to the preceding state of expansion again.
