Description

Closed electrothermal melting sleeve

Technical Field

The utility model relates to an electric hot melting cover especially relates to a closed electric hot melting cover.

Background

The electric heat fuse cover is used for the joint department of tubular product, often be used for heating power pipeline's joint department, carry out the sealed of joint department through the outer parcel coiled material of hot melt sheet among the prior art, but because the longitudinal joint needs the hot melt before the foaming, make the unsettled welding of longitudinal joint, cause longitudinal joint department hot melt inseparable very easily, it is poor to have caused the seal of hot melt cover, among the closed hot melt cover among the prior art, the electric heat silk screen causes harm and dislocation when round trip movement, influence joint hot melt area, lead to welding quality can not obtain guaranteeing.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a closed electric hot melting cover adopts the tubular structure as the main part, has reduced the welding of longitudinal joint, has improved the leakproofness to electric heat silk screen is fixed reliable, can not cause the damage of electric heat silk screen and remove the quality that influences the joint when the pulling barrel.

In order to achieve the purpose, the utility model provides a close electric heat melts cover, include the barrel, be fixed in the electric heat silk screen and the wire at the inboard both ends of barrel, the electric heat silk screen inlay in the barrel is inboard and fixed through a plurality of staples, the staple is the U type nail, U type nail parallel arrangement is two rows, the edge of electric heat silk screen both sides is provided with the fixed strip.

Preferably, the edges of the two sides of the electric heating wire mesh are arranged between the cylinder body and the fixing strips, and the cylinder body and the fixing strips are made of polyethylene materials.

Preferably, a through hole is formed in the side face of the barrel, one end of the wire is connected with the electric heating wire mesh, the middle of the wire is embedded in the side wall of the barrel, and the other end of the wire penetrates through the through hole to be connected with a power supply.

Preferably, the width of the electric heating wire mesh is 10-20 mm.

Therefore, the utility model adopts the above structure a closed electric hot melt cover adopts the tubular structure as the main part, has reduced the welding of longitudinal joint, has improved the leakproofness to electric heat silk screen is fixed reliable, can not cause electric heat silk screen's damage and removal to influence the quality that connects when the pulling barrel.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description

Examples

Fig. 1 is the utility model relates to a close electrothermal welding cover structure sketch map, fig. 2 is the utility model relates to a close electrothermal welding cover side view, fig. 3 is the utility model discloses barrel development structure sketch map, as shown in the figure, a close electrothermal welding cover includes barrel 1, is fixed in the electric heat silk screen 2 and the wire 5 at 1 inboard both ends of barrel, adopts tubular structure as the main part, has reduced the welding of longitudinal joint, has improved the leakproofness. The width of the electric heating wire net 2 is 10-20mm, and the electric heating wire net 2 with the width of 15mm is adopted in the embodiment. Electric heat silk screen 2 inlays through the hot pressing and adorns in 1 inboards of barrel and fixed through a plurality of staple 3, and this embodiment staple 3 are the U type nail, and U type nail parallel arrangement has two rows for electric heat silk screen 2 attaches in 1 inboards of barrel all the time in transportation and use, guarantees that electric heat silk screen 2 is fixed reliable. The edge of 2 both sides of electric heat silk screen is provided with fixed strip 4, and the edge of 2 both sides of electric heat silk screen sets up between barrel 1 and fixed strip 4, and barrel 1 and fixed strip 4 are the polyethylene material and make, guarantee that barrel 1 can not harm electric heat silk screen 2 when the pipeline removes, also guarantee simultaneously that electric heat silk screen 2 can not remove. Through-hole 11 has been seted up to barrel 1 side, and 5 one end of wire is connected with electric heat silk screen 2, and 5 middle parts of wire are embedded in the inside of barrel 1 lateral wall, and the wire 5 other end passes through-hole 11 and is connected with the power for supply power for electric heat silk screen 2.

The specific operation is as follows:

there are two relative pipelines in joint department, locate one of them pipeline with barrel 1 cover, connect two pipelines after, pull barrel 1 to joint department for the electric heat silk screen 2 at barrel 1 both ends sets up in two pipelines are relative, and through the fixed barrel 1 both ends of fixing the hoop, start the power that is connected with wire 5, carry out the hot melt. In the operation engineering, the barrel is required to move on the pipeline, and the fixing nails 3 and the fixing strips 4 are arranged, so that the electric heating wire mesh is fixed reliably, and the damage and the movement of the electric heating wire mesh cannot be caused when the barrel is pulled to influence the quality of the joint.

The above are specific embodiments of the present invention, but the scope of protection of the present invention should not be limited thereto. Any changes or substitutions which can be easily conceived by those skilled in the art within the technical scope of the present invention are covered by the protection scope of the present invention, and therefore, the protection scope of the present invention is subject to the protection scope defined by the claims.
