Description

Connecting valve and air conditioning unit

Technical Field

The application relates to a valve, especially relate to connecting valve and air conditioning unit.

Background

With the development of technology, more and more parts suppliers have introduced flameless quick connections for pipes. Some field installation and repair services have also begun to attempt these flameless quick connections. In order to meet the requirement, more and more air conditioner manufacturers start to upgrade their designs, and hopefully, the air conditioner manufacturers can be compatible with the traditional welding mode and the flameless quick connection mode.

The flameless quick connection puts higher requirements on the flatness and the length of the copper pipe. At present, under the condition that an indoor unit and an outdoor unit are in a flameless quick connection mode, in order to ensure enough operation space, a pipeline at a stop valve of the outdoor unit needs to be lengthened, but the lengthened pipeline causes the packing space (or the packing volume) of the whole machine to be enlarged, so that the packing amount of a container is reduced, and the cost is obviously increased.

Exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following embodiments, features of the embodiments can be supplemented with each other or combined with each other without conflict.

Referring to fig. 1 and 2, the connection valve of the present application may be a stop valve, a reversing valve, or the like, and includes a valve body 1 and a first connection pipe 2 connected to the valve body 1 and being bendable and/or stretchable. The flexible connection includes that the first connection pipe 2 can be wound into a plurality of turns or become a bending curve or the like, in short, since the first connection pipe 2 can be bent or extended, the space occupied by the combination body of the connection valve and the corresponding component can be reduced after the connection valve is assembled with the corresponding component, thereby increasing the container loading amount of the container. For example, the connection valve is a stop valve, and after the stop valve is installed on the air conditioner external unit, when the space occupied by the connection part connected with the first connection pipe 2 and the connection pipe is large, the first connection pipe 2 can be bent and hung on the outer shell of the air conditioner external unit through a ribbon, so that the purpose of reducing the whole casing volume is achieved. The telescopic first connecting pipe 2 means that the first connecting pipe 2 can be lengthened or reduced in size, for example, the first connecting pipe 2 is shortened when the size is reduced, and the first connecting pipe 2 is shortened under the condition that the space occupied by the corresponding parts connected with the connecting valve is larger, so that the packing volume occupied by the first connecting pipe 2 and the corresponding parts connected with the first connecting pipe 2 cannot be increased, and the purpose of reducing the whole packing volume is achieved. Of course, in some ways, the first connection tube 2 may be a connection tube that can be both curved and telescopic.

Referring to fig. 1 and 2, in one embodiment, the bendable first connecting tube 2 is a metal hose. Further, the metal hose may be a corrugated tube or a braided hose, etc.

Referring to fig. 1 and 2, in one embodiment, the first connection pipe 2 is welded to the valve body 1 or is screwed with the valve body 1. Through with first connecting pipe 2 weld in valve body 1 makes things convenient for first connecting pipe 2 install in valve body 1 also conveniently processes valve body 1 and first connecting pipe 2. And the mode of adopting threaded connection, need process the screw thread and set up adapting unit such as relevant flange on first connecting pipe 2 and valve body 1, though installation and processing are convenient to a certain extent, nevertheless can not be like the welding mode, can be convenient install first connecting pipe 2 in valve body 1 and conveniently process valve body 1 and first connecting pipe 2.

Referring to fig. 1 and 2, in order to satisfy the requirements of the conventional welding method and the flameless quick connection method in the case of reducing the volume of the container, in one embodiment, the connection valve includes a valve body 1, a first connection pipe 2 and a second connection pipe 3, which are bendable and/or telescopic. The second connection pipe 3 includes a connection section 31 connected to the first connection pipe 2 and a joint 32 connected to the connection section 31. In one embodiment, the second connecting tube 3 is a rigid connecting tube, such as a copper tube or the like.

Referring to fig. 1 and 2, in an embodiment, the connection section 31 of the second connection pipe 3 is welded or screwed to the first connection pipe 2, and the advantages of the welding and screwing manners refer to the advantages of the first connection pipe 2 welded to the valve body 1 or screwed to the valve body 1.

Referring to fig. 3 and 4 in conjunction with fig. 1 and 2, the present application further discloses an air conditioning unit including an outdoor unit 4 and any one of the above-mentioned connecting valves. Fig. 3 and 4 show two connection valves, which are both stop valves, one connection valve being a gas valve and the other connection valve being a liquid valve, the liquid valve being designated 10 and the gas valve being designated 20 for the sake of distinction, and correspondingly the valve body of the liquid valve 10 being designated 1a and the valve body of the gas valve 20 being designated 1 b. More specifically, the valve body 1a of the liquid valve 10 and the valve body 1b of the air valve 20 are attached to the outdoor unit 4. The second connection pipe 3 is connected to the indoor unit as the corresponding member connected to the first connection pipe 2.

With continued reference to fig. 1 in conjunction with fig. 3 and 4, it is illustrated by way of example how the connection valve reduces packaging space and meets conventional welding and flameless quick connections (which may also be referred to as flameless quick connections). The state in which the connection valve is mounted to the air conditioner outdoor unit 4 is shown in fig. 3, and the first connection pipe 2 is not bent in this state. When the space occupied by the second connection pipe 3 is large, the first connection pipe 2 is bent as shown in fig. 4, and the bent pipe is fixed on the outdoor unit through a rolling belt, thereby effectively saving the packing volume. When the conventional welding method is adopted, the field pipeline is directly inserted into the connector 32 (area a shown in fig. 1) of the second connecting pipe 3, and then the operation is performed according to the conventional welding method. When a flameless quick connection is used, the connection head 32 is cut away, and if necessary, a portion of the connection section 31 is also included (the cut away area is shown in the area a of fig. 1), and then a flameless quick connection is used to connect a portion of the connection section 31 (shown in the area B of fig. 1) to the field line.

Although the above embodiment is described by taking the second connection pipe 3 as a connection copper pipe and the connection valve as a stop valve as an example, a person skilled in the art can know that, in the case that the connection valve is a reversing valve or other valve, how to connect the second connection pipe 3 with other components may adopt the prior art, and details are not described again.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
