Abstract

A hot-and-cold water integrated water pipe comprises an outer cold water pipe, an inner hot water pipe, a supporting strip and a water pipe faucet. The outer cold water pipe is sleeved outside the inner hot water pipe, the outer cold water pipe and the inner hot water pipe are connected and support each other through the supporting strip, and the outer cold water pipe and the inner hot water pipe are both connected with the water pipe faucet. According to the hot-and-cold water integrated type water pipe, a pipe-in-pipe structure is adopted, the water pipe is capable of bending when the water pipe is distributed, and the trouble that in the prior art a hot water pipe and a cold water pipe need to be arranged in parallel and redundant bending connectors or bridge-crossing connectors are need for connection at corners are saved. The hot-and-cold water integrated water pipe is simple to construct, capable of being applied to kinds of complex construction environments, and reducing installing cost. Due to the fact that the cold water pipe is sleeved outside the inner hot water pipe, pressure difference and temperature difference of inside and outside of the hot water pipe are reduced, and the hot water pipe is effectively protected. The inner water pipe and the outer water pipe support each other, the phenomenon that one single water pipe deforms and the pipe wall displaces is avoided, and therefore the defects that an existing water pipe is complex to construct and is prone to leakage are overcome.

Description

A kind of hot cold water integrated water pipe

Technical field

The utility model Manifold technology field of paddling is specifically related to a kind of hot cold water integrated water pipe.

Background technique

At present, indoor water pipe adopts the PPR straight tube substantially, hot-water line is what to separate with cold water pipe, and this water pipe can not be crooked, need turning joint or bridge joint to connect in each place that will turn, this has just caused construction complicated, and cost also increases, and has also increased the risk of water toward external leakage simultaneously.

The model utility content

For the deficiency that above-mentioned prior art exists, the purpose of this utility model provides that a kind of stringing is simple, easy construction and reduce the flexible hot cold water integrated water pipe of the risk that leaked water leaks.

The technical solution of the utility model is: a kind of hot cold water integrated water pipe, comprise outer cold water pipe, interior hot-water line, supporting bar and water pipe adapter, described outer cold water pipe is enclosed within interior hot-water line outside, outer cold water pipe and interior hot-water line interconnect support by supporting bar, and outer cold water pipe all is connected with water pipe adapter with interior hot-water line.

Water pipe adapter is comprised of permanent joint, retainer ring and locking nut, wherein permanent joint divides large joint part and little joint part, have several water channel grooves with little joint part joint in the large joint part, large joint part is provided with outside thread, outer cold water pipe is enclosed within large joint part outside, interior hot-water line is enclosed within little joint part outside, also has seal ring on the little joint part; Retainer ring overlaps the outside outside of cold water pipe, and retainer ring is compressed and be threaded connection with outer cold water pipe with locking nut.

The utility model has the advantages that: 1, the utility model adopts the tube-in-tube structure form, can be crooked around the corner when stringing, having save in the past heat, cold water pipe needs trouble that stringing arranged side by side brings and needs unnecessary turning joint or bridge joint to connect at the turning, it is relatively simple to construct, applicable to the construction environment of various complexity, also reduced installation cost; 2, the hot-water line outside has the cold water pipe box; reduced the poor and temperature difference of hot-water line pipe external and internal pressure, effectively protected hot-water line, interior outer water pipe supports mutually; avoid single water pipe distortion and tube wall inconsistent phenomenon, thereby overcome the shortcomings such as existing water pipe construction complexity and easy leakage.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is inside and outside water pipe structure sectional view described in the utility model.

Embodiment

Now by reference to the accompanying drawings, the utility model is further described.

As shown in Figure 1 and Figure 2, a kind of hot cold water integrated water pipe, comprise outer cold water pipe 1, interior hot-water line 2, supporting bar 3 and water pipe adapter, described outer cold water pipe 1 is enclosed within interior hot-water line 2 outsides, outer cold water pipe 1 interconnects support with interior hot-water line 2 by supporting bar 3, and outer cold water pipe 1 all is connected with water pipe adapter with interior hot-water line 2.

Water pipe adapter is comprised of permanent joint 4, retainer ring 5 and locking nut 6, wherein 4 minutes large joint parts 4.1 of permanent joint and little joint part 4.2, have several water channel grooves with little joint part 4.2 joints in the large joint part 4.1, large joint part 4.1 is provided with outside thread, outer cold water pipe 1 is enclosed within large joint part 4.1 outsides, interior hot-water line 2 is enclosed within little joint part 4.1 outsides, also has seal ring on the little joint part 4.1; Retainer ring 5 overlaps the outside outside of cold water pipe 1, and with locking nut 6 retainer ring 5 is compressed and is threaded connection with outer cold water pipe 1, thereby with outer cold water pipe 1 and 2 lockings of interior hot-water line.In use, hot water by integrated water pipe interior hot-water line 2 and flowed out by the little joint part 4.1 of water pipe adapter, cold water then goes out by the outer cold water pipe 1 of integrated water pipe and by several water channel concentrated flows that have with little joint part 4.2 joints in the large joint part 4.1.
