Description
Technical Field
The utility model relates to the technical field of building energy-saving equipment, in particular to a hot water pipeline connecting structure with heat preservation performance.
Background
In modern buildings, hot water pipelines are often laid in the buildings, long hot water pipeline laying systems and pipeline joints are an important technology. Both the convenience and the stability of the pipe connection are taken into consideration, and the heat preservation performance of the hot water pipe is also taken into consideration, otherwise, more heat loss is caused at the joint.
The PVC pipe of current hot-water line universal use, consequently, the connecting piece often also adopts the PVC material, and although it is convenient to connect, nevertheless do not possess the heat preservation effect, and the durability performance is relatively poor simultaneously, and especially used repeatedly's performance is relatively poor, because the restriction of PVC material characteristic, its interface sets up threaded construction less easily, even if set up, the frequent easy sliding opening of easy very of dismouting.
SUMMERY OF THE UTILITY MODEL
The utility model provides a double-layer pipeline connecting structure which has heat insulation performance, is convenient to connect, and is stable and durable.
The hot water pipeline connecting structure with heat preservation performance is characterized in that the connecting structure is a double-layer structure, the outer layer is a metal protective shell, and the inner layer is a heat insulation inner pipe with heat insulation and preservation functions;
the heat insulation inner pipe is provided with a plug-in connector at the pipe fitting interface, the surface of the plug-in connector is provided with anti-skid convex patterns, the outer diameter of the plug-in connector is smaller than the inner diameter of the metal protective shell, and the outer part of the plug-in connector is sleeved with a rubber sealing ring;
an internal thread groove is formed in the inner wall of the end portion of the metal protective shell, a fastener is arranged on the water pipe connector, an external thread groove is formed in the outer wall of the fastener and matched with the internal thread groove formed in the inner wall of the end portion of the metal protective shell, and a through groove is formed in the center of the fastener; the through groove consists of a cylindrical groove section and a horn-shaped groove section, the inner diameter of the cylindrical groove section is slightly larger than the outer diameter of the hot water pipe, and the inner diameter of the wide part of the horn-shaped groove section is slightly larger than the inner diameter of the cylindrical groove section.
According to the hot water pipeline connecting structure with the heat preservation performance, the heat preservation performance of the device is effectively poor by arranging the heat insulation inner pipe in the metal protection shell and arranging the plug-in connector matched with the hot water pipe in size on the heat insulation inner pipe, and meanwhile, the metal protection shell has high firmness, is convenient to assemble and disassemble and is durable. The rubber seal ring is arranged to seal and fix the hot water pipe, and the water leakage problem of the joint of the pipe fittings can be avoided through the design.

Detailed Description
Example 1: the hot water pipeline connecting structure with heat preservation performance is a three-way structure 12 pipe fitting. The pipe fitting is of a double-layer structure, the outer layer is a metal protective shell 1, and the inner layer is a heat insulation inner pipe 5 with heat insulation and heat preservation functions. The heat insulation inner pipe 5 is provided with a plug 6 at the pipe fitting interface for connecting the hot water pipe 2.
The plug 6 on set up anti-skidding burr 7, its external diameter is less than metal protective housing 1 internal diameter, makes to form the space between plug 6 and the thermal-insulated inner tube 5, this space forms water pipe water receiving mouth 3, the internal thread groove 4 that sets up on the metal protective housing 1 tip inner wall for fixing fastener 9. The fastness that anti-skidding convex line 7 can increase hot-water line 2 and bayonet joint 6 and be connected, and rubber seal 8 has been cup jointed to the outside of bayonet joint 6 for the sealed and fixed of device.
The water pipe connector 3 is provided with a fastening piece 9, the outer wall of the fastening piece 9 is provided with an external thread groove 10, the external thread groove 10 is matched with an internal thread groove 4 arranged on the inner wall of the end part of the metal protective shell 1, and the center of the fastening piece 9 is provided with a through groove 11. The through groove 11 consists of a cylindrical groove section and a horn-shaped groove section, and the inner diameter size of the cylindrical groove section is slightly larger than the outer diameter size of the hot water pipe 2 so as to ensure that the hot water pipe 2 can penetrate into the through groove 11; the inner diameter of the flared groove section at the width is slightly larger than that of the cylindrical groove section so as to place the sealing ring.
When the hot water pipe joint is used and installed, the hot water pipe 2 penetrates through the through groove 11 and the sealing ring 8 of the fastening piece 9, then the end part of the hot water pipe 2 is sleeved on the plug-in connector 6, the inner wall of the hot water pipe 2 is tightly pressed on the anti-skid convex pattern 7 of the plug-in connector 6, then the fastening piece 9 is rotated to slowly connect the hot water pipe joint into the water pipe joint 3, so that the rubber sealing ring 8 is clamped between the horn-shaped groove section inner wall of the through groove 11 and the outer wall of the hot water pipe 2, and a sealing effect is achieved. When the disassembly is needed, the fastener 9 is only required to be screwed reversely to be loosened.
Example 2: the hot water pipeline connecting structure with heat preservation performance is a bent connecting structure 13 pipe fitting, and the connecting structure and the connecting mode are the same as those of the embodiment 1.
Example 3: the hot water pipeline connecting structure with heat preservation performance is a direct structure 14 pipe fitting, and the connecting structure and the connecting mode are the same as those of the embodiment 1.
