The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application. Furthermore, it should be understood that the detailed description is presented herein for purposes of illustration and explanation only and is not intended to limit the present application. In this application, unless otherwise indicated, terms of orientation such as "upper" and "lower" are used to generally refer to the upper and lower positions of the device in actual use or operation, and specifically the orientation of the drawing figures; while "inner" and "outer" are for the outline of the device.
The embodiment of the application provides a valve structure and an air conditioner, and the valve structure and the air conditioner are described in detail below. The following description of the embodiments is not intended to limit the preferred embodiments.
Referring to fig. 1 and 2, the valve structure includes a valve body 1, a first connecting pipe 11, and a second connecting pipe 12. The valve body 1 has a passage 14 inside. The first connecting pipe 11 extends from the valve body 1. The second connection pipe 12 extends from the valve body 1. The second connection pipe 12 has an external structure different from the first connection pipe 11, and the first connection pipe 11 and the second connection pipe 12 are selectively connected to the passage 14.
It can be appreciated that the external connection structure of the first connection pipe 11 and the second connection pipe 12 is different, and the first connection pipe 11 can be selectively used to connect with an external device (for example, an indoor pipeline connected with an indoor unit in an air conditioner) or the second connection pipe 12 can be used to connect with the external device according to the difference of the ignition point of the refrigerant, so that the connection mode of the valve body 1 and the external device is increased.
In the present embodiment, one of the external connection structure of the first connecting pipe 11 and the external connection structure of the second connecting pipe 12 is a threaded external connection structure 111, and the other is a straight pipe external connection structure 121. When the ignition point of the refrigerant is low, the valve structure can be connected with the external device through the threaded external structure 111, so that the problem of safety risk existing in the connection of the valve structure and the external device in a welding connection mode when the ignition point of the refrigerant is low can be avoided. When the ignition point of the refrigerant is higher, the threaded external connection structure 111 or the straight pipe external connection structure 121 can be selected to be connected with an external device according to actual conditions, so that the selection diversity of users is improved, and the user experience is improved.
In this embodiment, the external connection structure of the first connection pipe 11 is a threaded external connection structure 111, and the external connection structure of the second connection pipe 12 is a straight pipe external connection structure 121. The first connecting pipe 11 and the second connecting pipe 12 are positioned on the same side of the valve body 1, and the extending directions are consistent.
In other embodiments, the external connection structure of the first connection pipe 11 is a straight pipe external connection structure 121, and the external connection structure of the second connection pipe 12 is a threaded external connection structure 111. The first connecting pipe 11 and the second connecting pipe 12 are respectively positioned at two sides of the valve body 1, and the extending directions are opposite, so that the connecting directions of the first connecting pipe 11 and the second connecting pipe 12 can be changed after the valve body 1 rotates for one hundred eighty degrees.
Further, the valve structure further includes a third connection pipe 13 extending from the valve body 1, and the third connection pipe 13 communicates with the passage 14 and is used for connection with another external device (for example, an air conditioner outdoor unit).
In the present embodiment, the external device connected to the first connection pipe 11 or the second connection pipe 12 is an upstream device, and the external device connected to the third connection pipe 13 is a downstream device. The refrigerant flows into the passage 14 from the first connection pipe 11 or the second connection pipe 12 into the valve body 1, then flows from the valve body 1 to the third connection pipe 13, and then flows to the downstream device through the third connection pipe 13.
In other embodiments, the external connection device connected to the third connection pipe 13 may be an upstream device, and the external connection device connected to the first connection pipe 11 or the second connection pipe 12 may be a downstream device, that is, the refrigerant flows from the third connection pipe 13 into the channel 14 into the valve body 1, then flows from the valve body 1 to the first connection pipe 11 or the second connection pipe 12, and then flows to the downstream device.
Further, the extending direction of the third connecting pipe 13 is different from the extending direction of the first connecting pipe 11 and the second connecting pipe 12.
Specifically, the first connecting pipe 11 and the second connecting pipe 12 are located on the same side of the valve body 1 and have the same extending direction, the third connecting pipe 13 and the first connecting pipe 11 are located on the opposite side of the valve body 1, and the extending direction is opposite to the extending direction of the first connecting pipe 11. Therefore, the third connecting pipe 13 is conveniently distinguished from the first connecting pipe 11 and the second connecting pipe 12, so that an installer can quickly and accurately find a pipeline to be connected on the valve body 1.
It should be noted that the reverse extension line of the third connecting tube 13 may be located between the first connecting tube 11 and the second connecting tube 12, so that the first connecting tube 11, the second connecting tube 12, and the third connecting tube 13 are uniformly distributed on the side wall of the valve body 1.
In some embodiments of the present application, the valve structure further comprises a switching mechanism 2. The switch mechanism 2 is disposed on the valve body 1 and is used for controlling the on/off of the first connecting pipe 11 and the channel 14 and the on/off of the second connecting pipe 12 and the channel 14.
Specifically, when it is necessary to connect the upstream device with the first connecting pipe 11, the switching mechanism 2 is in the first state, and the passage 14 is communicated with the first connecting pipe 11, so that the refrigerant flows into the valve body 1 through the first connecting pipe 11 having the screw-thread external connection structure 111. When the second connecting pipe 12 is required to connect the upstream device, the switch mechanism 2 is in the second state, and the channel 14 is communicated with the second connecting pipe 12, so that the refrigerant flows into the valve body 1 through the second connecting pipe 12 with the straight pipe external connection structure 121.
In the present embodiment, the switching mechanism 2 includes a first switching valve 21 and a second switching valve 22. The first switch valve 21 is disposed in the channel 14 and close to the first connection pipe 11, for controlling on/off of the first connection pipe 11 and the channel 14. The second switch valve 22 is disposed in the channel 14 and close to the second connection pipe 12, for controlling on/off of the second connection pipe 12 and the channel 14.
When the first connecting pipe 11 and the second connecting pipe 12 are simultaneously connected to the upstream device, the first connecting pipe 11 is communicated with the channel 14, and the second connecting pipe 12 is not communicated with the channel 14 by controlling the first switch valve 21 and the second switch valve 22; alternatively, the first connection pipe 11 is not communicated with the passage 14, and the second connection pipe 12 is communicated with the passage 14; alternatively, the first connecting pipe 11 is communicated with the channel 14, and the second connecting pipe 12 is communicated with the channel 14; alternatively, the first connection pipe 11 is not communicated with the passage 14, and the second connection pipe 12 is not communicated with the passage 14.
Specifically, the first switch valve 21 and the second switch valve 22 are respectively disposed at two ends of the valve body 1 in the length direction, and the first switch valve 21 and the second switch valve 22 have the same structure, and each of them includes a nut screwed to the end of the valve body 1, and a valve core connected to the nut, and the valve core is driven to move in the channel 14 by the rotation of the nut, so that the valve core moves to close or far away from the orifice connected to the first connecting pipe 11 and the channel 14, and moves to close/far from the orifice connected to the second connecting pipe 12 and the channel 14, thereby achieving the on/off of the first connecting pipe 11 and the channel 14 or the on/off of the second connecting pipe 12 and the channel 14.
In some embodiments of the present application, the valve structure further comprises: the valve thimble 323 is arranged on the valve body 1 and used for conducting the channel 14 with the outside of the valve body 1, and the valve thimble 323 is used for guiding a refrigerant into the valve body 1 or vacuumizing the inside of the valve body 1, so that when the refrigerant needs to be added, the refrigerant is added into the channel 14 by opening the valve thimble 323, and when the vacuumizing is needed, the valve thimble 323 is opened to perform vacuumizing test on the valve body 1.
In the present embodiment, valve needle 323 includes a first valve needle 32313 and a second valve needle 323. The first valve needle 32313 is disposed on the valve body 1 and is adjacent to the first connecting tube 11. The second valve needle 323 is disposed on the valve body 1 and near the second connecting pipe 12.
Specifically, the first valve needle 32313 and the second valve needle 323 are both located on the same side wall in the length direction of the valve body 1.
In other embodiments, the number of the valve pins 323 may be one, and a single valve pin 323 is disposed on the valve body 1 and located between the extension lines of the first connecting pipe 11 and the second connecting pipe 12, so as to add refrigerant to the channel 14 or perform a vacuum test on the interior of the valve body 1.
