Description
Technical field
The present invention relates to air-conditioning four-way valve technical fields, and in particular to a kind of air-conditioning four-way valve connection with filtering function
Head.
Background technology
Four-way valve is connect with indoor unit, outdoor unit, compressor, plays the role of the switching of cooling and warming.Traditional four-way valve
Connecting tube and the copper pipe of indoor unit, the copper pipe of outdoor unit, compressor copper pipe between generally connected by welding
It connects.Since air-conditioning refrigerant is frequently necessary to carry out supplement filling, it is easy to be mixed into impurity, impurity can cause after entering in four-way valve
Sliding block or piston blocking in four-way valve block, and four-way valve is caused to lose switching effect.At this time four-way valve can only disassemble into
Row is replaced.
Invention content
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of air-conditioning four-way with filtering function
Valve connector, for by the connecting tube of the four-way valve company between indoor unit copper pipe, outdoor unit copper pipe, compressor copper pipe respectively
It connecing, which is characterized in that the connecting tube of the four-way valve, indoor unit copper pipe, outdoor unit copper pipe, compressor copper pipe have expansion mouth,
The end of expansion mouth is respectively provided with the first welding ring, and the inner wall of expansion mouth has internal thread, and the connector includes tube body, tube body
Both ends there is the external screw thread that matches with internal thread, there are two the second welding ring, the second welding ring difference for the middle part tool of tube body
Positioned at externally threaded end, filter screen is installed in the middle part of the tube body.
Expansion mouth includes tapered portion and isometrical portion, and internal thread is located at isometrical portion's inner wall, the both ends of the tube body have with
The tip that tapered portion matches.
Tube body is copper pipe.
Filter screen is copper filter screen.
The present invention operation principle be：The tip of tube body one end is inserted into the connecting tube of four-way valve, the tip of the other end is inserted
Enter in indoor unit copper pipe, outdoor unit copper pipe or compressor copper pipe, turn tube body, tube body both ends are screwed into the connection of four-way valve respectively
In pipe and indoor unit copper pipe, outdoor unit copper pipe or compressor copper pipe, until the first welding ring and the second welding ring are adjacent to.By first
Welding ring is welded with the second welding ring.Complete four-way valve connecting tube and indoor unit copper pipe, outdoor unit copper pipe, compressor copper pipe it
Between connection.
The beneficial effects of the invention are as follows：The air-conditioning four-way valve connector of the present invention, can be effectively by the connection of four-way valve
Pipe is attached with indoor unit copper pipe, outdoor unit copper pipe, compressor copper pipe, and connector has filtration, and can be dismantled clear
Reason improves the service life of air-conditioning four-way valve.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
In conjunction with attached drawing, the invention will be further described.
As shown in Figure 1, a kind of air-conditioning four-way valve connector with filtering function, for the connecting tube 1 of four-way valve to be divided
Connection not between indoor unit copper pipe 2, outdoor unit copper pipe 2, compressor copper pipe 2, which is characterized in that the connection of the four-way valve
Pipe 1, indoor unit copper pipe 2, outdoor unit copper pipe 2, compressor copper pipe 2 have expansion mouth 3, and the is respectively provided on the outside of the end of expansion mouth 3
One welding ring 4, the inner wall of expansion mouth 3 have internal thread, and the connector includes tube body 5, and the both ends of tube body 5 have and interior spiral shell
The external screw thread 6 that line matches, there are two the second welding rings 7, the second welding ring 7 to be located at externally threaded end respectively for tool on tube body 1,
The middle part of the tube body 5 is equipped with filter screen 8.
Expansion mouth 3 includes tapered portion 9 and isometrical portion 10, and internal thread is located at isometrical 10 inner wall of portion, the both ends of the tube body 5
With the tip 11 to match with tapered portion 9.
Tube body 5 is copper pipe.
Filter screen 8 is copper filter screen.
The tip 11 of 5 one end of tube body is inserted into the connecting tube 1 of four-way valve, the tip 11 of the other end be inserted into indoor unit copper pipe 2,
In outdoor unit copper pipe 2 or compressor copper pipe 2, tube body 5 is turned, 5 both ends of tube body are screwed into connecting tube 1 and the interior of four-way valve respectively
In machine copper pipe 2, outdoor unit copper pipe 2 or compressor copper pipe 2, until the first welding ring 4 and the second welding ring 7 are adjacent to.By the first weldering
Ring 4 is connect to weld with the second welding ring 7.Complete the connecting tube 1 of four-way valve and indoor unit copper pipe 2, outdoor unit copper pipe 2, compressor copper
Connection between pipe 2.When needing to clear up the filter screen in connector, the first welding ring 4 and the second welding ring 7 are cut, you can
Convenient cleaning filter screen, then again connect connector.Due to the filtration of filter screen 8 in connector, the cunning of four-way valve
Block and piston, which are not easily susceptible to impurity effect, causes four-way valve to damage, so as to improve the service life of four-way valve.
The preferred embodiment of the present invention described in detail above, it should be understood that those of ordinary skill in the art without
Creative work is needed according to the present invention can to conceive and makes many modifications and variations, therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
