Abstract
The utility model relates to a connecting pipe for an indoor unit and an outdoor unit of a split air conditioner, which uses aluminium pipe, or copper pipe, or stainless steel pipe as base material, and the inner surface and the outer surface of the base material are connected with cross linked polyethylene layers; the inner part of one end of a pipe joint is provided with threads and a conical surface, and the surface of the other end is provided with an annular groove and a clamping groove; the utility model has good sealing performance, corrosion resisting performance, convenient bend, long service life, and low cost.
Description
Technical field
The utility model relates to the member of split-type air conditioner, is specifically related to a kind of tube connector of detachable air conditioner indoor unit and outdoor unit.
The utility model also relates to the pipe joint of this tube connector and indoor unit and outdoor unit.
Background technology
The indoor unit and outdoor unit tube connector of existing detachable air conditioner generally adopts copper pipe to make, copper pipe cost height, and repeatedly easily cause pipe to split after the bending, and cause coolant leakage.Fig. 1 is the pipe joint structure schematic diagram of existing tube connector and air-conditioner indoor unit and outdoor unit, as shown in the figure, it is the copper screw cap of establishing the screw thread 1 and the conical surface 2 in one, during use, the screw thread 1 of indoor or outer joint 3 precession copper screw caps is fastening, the horn mouth of copper pipe 4 and the inner conical surface of copper screw cap coincide and with the conical surface seal of joint 3.At present, people are always for seeking a kind of with low cost, reliably tube connector effort easily.
The utility model content
The purpose of this utility model is to provide a kind of detachable air conditioner indoor unit and outdoor unit tube connector at the problem of prior art existence, has excellent sealing performance and decay resistance, and is crooked convenient, long service life, and cost declines to a great extent than copper connecting tube.
The purpose of this utility model also is to provide the pipe joint of this tube connector and indoor unit and outdoor unit.
The indoor unit and outdoor unit tube connector of split-type air conditioner of the present utility model is a base material with aluminum pipe, copper pipe or stainless steel tube, and inside and outside surface connects the crosslinked polyethylene layer.
The inside and outside surface of base material and crosslinked polyethylene can pass through the thermosol bonding connection.
The crosslinked polyethylene layer on described base material and two surfaces obtains tube connector of the present utility model with thermosol by a step co-extrusion.
Establish the screw thread and the conical surface in pipe joint one end of tube connector of the present utility model, annular groove and draw-in groove are established in the surface of the other end.Described annular groove is used to install sealing ring, and the port card of tube connector is in draw-in groove.
For tube connector is stuck in the draw-in groove securely, add dead ring, tube connector is combined between sealing ring and the dead ring, firmly be connected with pipe joint.
Described sealing ring mounting groove can be established one or more as required.
During use, an end of pipe joint is connected with indoor or outer machine joint screw thread by the interior screw thread of establishing, establishes the conical surface in the pipe joint and be connected with indoor or outer machine joint conical surface seal; The groove on other end surface is installed sealing ring and tube connector, and the port card of tube connector is fixing in draw-in groove.
The utility model compared with prior art has following advantage:
1. Zhong Jian aluminium lamination can permeate favorable sealing property by 100% isolated gas;
2. chemical property is highly stable, and corrosion resistance is strong, can not leak refrigerant because of corrosion;
3. ageing-resistant performance is superior, reaches 50 years service life;
4. inner wall smooth, drag losses is few when carrying fluid, and because its unique composite structure integrates hard and soft, can eliminate the compression shock in the pipe-line system rapidly;
5. has good flame retardancy;
6. thermal conductivity factor is low, is difficult for frosting, good heat preservation performance;
7. flexible difficult bounce-back, easy to install succinct;
8. the pipe seal of tube connector is good, and tube connector needn't be processed, and is easy to connect.
Description of drawings
Fig. 1 is the pipe joint structure schematic diagram of existing detachable air conditioner indoor unit and outdoor unit tube connector;
Fig. 2 is the structural representation of the utility model tube connector;
Fig. 3 is the pipe joint structure schematic diagram of tube connector shown in Figure 2;
Fig. 4 structural representation that to be pipe joint shown in Figure 3 be connected with the indoor unit and outdoor unit joint with tube connector.
The specific embodiment
As shown in Figure 2, the indoor unit and outdoor unit tube connector of split-type air conditioner of the present utility model is a base material with aluminum pipe 7, and the two sides connects crosslinked polyethylene layer 5,9; Inside and outside of aluminum pipe with crosslinked polyethylene by thermosol 6,8 bonding connections.
As shown in Figure 3, establish the screw thread 1 and the conical surface 2 in the utility model pipe joint one end, annular groove 10 and draw-in groove 11 are established in the surface of the other end.
As shown in Figure 4, an end of pipe joint is threaded with indoor or outer machine joint 3 by the interior screw thread 1 of establishing, establishes the conical surface 2 in the pipe joint and be connected with indoor or outer machine joint conical surface seal; The groove 10 on other end surface is installed sealing ring 14 and tube connector 12, and the port card of tube connector 12 is fixing in draw-in groove 11, and tube connector 12 surface cover dead rings 13 are stuck in the draw-in groove 11 together.
