Problems solved by technology

The current defrosting method is to rely on the four-way valve to change the air flow direction to control the overall defrosting of the evaporator. When defrosting, the condenser becomes an evaporator, and the heating is forced to stop, which reduces the heating efficiency of the air conditioner.

Embodiment 1

[0031] Example 1: A large-capacity defrost valve (see figure 1 , figure 2 , image 3 , Figure 4 ), which includes a valve body 2, the upper end of the valve body 2 is connected to the upper end cover 1, the valve body 2 is provided with a piston 6, the piston 6 is connected with the valve core 5 through the connecting rod 7, and is locked by the locking pad 12. The upper end of the connecting rod 7 is connected with the extension spring 4, and the upper end of the extension spring 4 is connected with the lower end of the upper end cover 1. The lower end of the spool 5 is provided with a small bonnet 10, the inside of the spool 5 is provided with a small spool 8, the lower part of the small spool 8 is covered with a small spring 9, the small spool 8 is lifted by the small spring 9, and the lower end of the small spring 9 Link to the small valve cover 10. The lower end of the valve body 2 is connected to the lower end cover 3, a gasket 11 is provided between the valve bod...

Embodiment ２

[0039] Embodiment 2: A large-capacity defrosting valve (see Figure 5 and Figure 6), its structure and principle are basically the same as Embodiment 1, the difference is that the fifth channel 17 and the small valve assembly are omitted, that is, there is no small The spool 8, the small spring 9, the small valve cover 10, the sixth passage 18 and the seventh passage 19 have only one stage of pressure relief.

[0040] When the high-temperature and high-pressure fluid in the second channel 14 arrives, the gas flow passes through the gap between the piston 6 and the partition 20, and throttles to the buffer chamber 21, and the piston 6 is forced upward to prevent the valve core 5 from moving downward. After the gap between the piston 6 and the valve body 2 is throttled to the power chamber 22, the upper surface of the piston 6 is stressed, pushing the piston 6 to move downward, but it is slowly lowered by the resistance of the buffer chamber 21. When the valve core 5 moves to the ...

Abstract

The invention discloses a large-capacity defrosting valve. The large-capacity defrosting valve is characterized by comprising a valve body (2), wherein an upper end cover (1) is connected to the valve body (2), a piston (6) is arranged in the valve body (2), the piston (6) is connected with a valve element (5), the upper end of the valve element (5) is connected with a tension spring (4), the upper end of the tension spring (4) is connected with the lower end of the upper end cover (1), the lower end of the valve body (2) is connected with a lower end cover (3), a first channel (13) and a second channel (14) are formed in the valve body (2), a third channel (15) is formed in the lower end cover, a fourth channel (16) is formed in the upper end cover (1), a power cavity (22) is formed between the piston (6) and the upper end cover (1), and a buffering cavity (21) is formed between the piston (6) and the valve body (2). When the large-capacity defrosting valve works, impact is avoided, the stability is high, the reliability is high, the service life is long, and the heating efficiency of an air conditioner is greatly improved.

Description

Technical field: [0001] The invention relates to a large-capacity defrosting, which belongs to the technical field of air-conditioning defrosting, and is used for segmental defrosting of an evaporator when the air-conditioning is heating. Background technique: [0002] When the air conditioner is heating, the evaporator will frost. If the frost is too thick, the heating efficiency will be reduced, so it is necessary to defrost the evaporator. The current defrosting method is to rely on the four-way valve to change the air flow direction to control the overall defrosting of the evaporator. When defrosting, the condenser becomes an evaporator, and the heating is forced to stop, which reduces the heating efficiency of the air conditioner. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a large-capacity defrosting valve with good structural stability, high reliability, long life, no hidden danger of ...
