Disclosure of Invention
The main object of the present utility model is to provide a stop valve and a pipe assembly, which can solve the above-mentioned problems.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a shut-off valve, comprising:
the valve body is provided with two openings, wherein one opening is a pipe connecting opening and is used for connecting a pipeline;
one end of the horn pipe is in a horn shape, and the end far away from the horn shape is connected to the other opening of the valve body;
the nut is movably arranged on the horn pipe, the inner diameter of one end of the nut, which is close to the valve body, is smaller than the diameter of one horn-shaped end of the horn pipe, and the diameter of one end of the nut, which is far away from the valve body, is larger than the diameter of one horn-shaped end of the horn pipe.
The utility model also provides a pipeline assembly for connecting the air conditioner outdoor unit and the indoor unit, which is characterized by comprising the following components:
a connecting pipe;
the first stop valves are adopted, and two connecting pipe ports of the two first stop valves are respectively connected to two ends of the connecting pipe;
the indoor stop valve is connected with a pipeline joint of the indoor unit through an opening at one end, and is connected with a nut of one of the first stop valves through threads through an opening at the other end;
and one end of the outdoor stop valve is connected with the pipeline joint of the outdoor unit, and the other end of the outdoor stop valve is connected with the threads of the other first stop valve.
Compared with the prior art, the utility model has the following beneficial effects:
the stop valve can be connected with a common stop valve by adopting a nut, further the stop valve can be arranged on the connecting pipe and connected with the indoor stop valve and the outdoor stop valve, when the air conditioner is disassembled, the indoor stop valve, the outdoor stop valve and the stop valve are closed, most of refrigerant in the connecting pipe is kept in the connecting pipe, so that the refrigerant is prevented from entering the atmosphere, the waste of the refrigerant is reduced, and the pollution of the refrigerant to the atmosphere is reduced.

Detailed Description
The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art.
Example 1
As shown in fig. 2, a stop valve comprises a valve body 11, two openings are arranged on the valve body 11, one of the openings is a connecting pipe 12, the other opening is provided with a horn pipe 13, one end of the horn pipe 13 is in a horn shape, the horn-shaped end is far away from the valve body 11, a nut 14 is movably arranged on the horn pipe 13, the diameter of one end of the nut 14 is larger than that of the horn-shaped end of the horn pipe 13, the diameter of the other end of the nut is smaller than that of the horn-shaped end of the horn pipe 13, so that the nut 14 cannot penetrate through the horn-shaped end of the horn pipe 13, and other threaded interfaces can be connected through the nut 14. The switching of the shut-off valve is the same principle as other types of shut-off valves in the prior art.
The horn 13 is made of a metal material. The nut 14 is made of copper material.
Example two
As shown in fig. 3 to 4, a pipe assembly for connecting an indoor unit and an outdoor unit of an air conditioner includes a connection pipe 103, two first shut-off valves 100 provided at both ends of the connection pipe 103, an outdoor shut-off valve 101 connected to the outdoor unit of the air conditioner, and an indoor shut-off valve 102 connected to the indoor unit of the air conditioner, wherein the first shut-off valves 100 are shut-off valves according to the first embodiment. One of the horn pipes 13 of the first stop valve 100 is connected with one end opening of the outdoor stop valve 101 through a nut 14, the other end opening of the outdoor stop valve 101 is connected with a pipeline joint of the outdoor unit, the other horn pipe 13 of the first stop valve 100 is connected with one end opening of the indoor stop valve 102 through the nut 14, and the other end opening of the indoor stop valve 102 is connected with a pipeline joint of the indoor unit. The two first stop valves 100 are respectively adjacent to the outdoor stop valve 101 and the indoor stop valve 102, and when the air conditioner needs to be disassembled, the indoor stop valve 101, the outdoor stop valve 102 and the two first stop valves 100 are respectively closed, and the refrigerant in the connecting pipe 103 is limited in the connecting pipe 103 by the first stop valve 100, so that most of the refrigerant in the connecting pipe 103 can be prevented from flowing out.
The indoor stop valve and the outdoor stop valve adopt stop valves in the prior art.
The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model, which is defined by the appended claims.
