Description

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an air-conditioning one-way valve component. Background Art

[0002] As people's living standards gradually improve, air conditioners have become a daily staple and have entered thousands of households. In air conditioners, one-way valves are important components. The one-way valve realizes the functions of forward conduction and reverse cutoff of the internal liquid through the movement of its internal valve core. The valve core of the existing one-way valve adopts a conical valve core. When performing reverse cutoff, the fluid will drive the valve core to resist the guide groove wall of the valve body, thereby causing the valve core to close the guide groove and prevent the fluid from flowing back. However, since the valve core directly collides with the guide groove wall, the surface of the valve core is prone to wear and deformation, which will affect the sealing between the valve core and the guide groove and reduce the reverse cutoff effect of the one-way valve. Therefore, it is necessary to design a new one-way valve structure to solve the above problems. Utility Model Content

In this way, the compression spring can gradually slow down the speed of the valve head and avoid the valve head from colliding rapidly with the guide groove, which makes the valve head easy to wear and deform, thereby improving the service life of the valve head.

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0017] like Figures 1 to 4As shown, an air-conditioning one-way valve assembly includes a valve body 1 and a valve core, wherein a first through groove 2 and a second through groove 3 are sequentially provided in the valve body 1 from left to right, and the first through groove 2 and the second through groove 3 are connected via a guide groove 4, a plurality of slide grooves 5 are provided on the side of the second through groove 3 close to the first through groove 2, and a compression spring 6 is provided in the slide groove 5, the valve core includes a valve head 7 and a valve cylinder 8, the valve cylinder 8 is slidably connected to the second through groove 3, and a plurality of limit seats 9 are provided in the second through groove 3, the valve cylinder 8 is connected to the valve head 7, and a plurality of guide grooves 10 are provided on the valve cylinder 8, a retaining ring 11 is provided on the valve head 7, and a plurality of sliding rods 12 are provided on the retaining ring 11, and the plurality of sliding rods 12 are correspondingly slidably connected to the plurality of slide grooves 5.

[0018] The working principle of the air conditioning one-way valve assembly described in the present invention is achieved through the cooperation between the valve body 1 and the valve core. Figures 1 to 4 As shown, the valve head 7 and the guide groove 4 are abutted against each other as the initial state for description. When the fluid flows in from the first through groove 2, the fluid abuts against the valve head 7 and drives the valve head 7 to move along the second through groove 3 to the limit seat 9. The slide rod 12 moves along the slide groove 5 with the valve head 7. When the valve head 7 abuts against the limit seat 9, the valve head 7 is separated from the guide groove 4 and the fluid enters the second through groove 3. The fluid enters the valve cylinder 8 from the guide groove 10 and is transported along the second through groove 3 after flowing out of the valve cylinder 8, thereby realizing the conduction effect. The valve head 7 is separated from the guide groove 4 as the initial state for description. When the fluid flows in from the second through groove 3, the fluid enters the valve cylinder 8 and impacts the valve head 7, causing the valve head 7 to move toward the guide groove 4. The slide rod 12 moves along the slide groove 5 with the valve head 7. The slide rod 12 abuts against the compression spring 6 and compresses the compression spring 6. The compression spring 6 gradually slows down the speed of the valve head 7 until the valve head 7 abuts against the guide groove 4. The valve head 7 closes the guide groove 4 and achieves a cut-off effect. Compared with the traditional one-way valve, the air-conditioning one-way valve assembly can avoid the valve head 7 from colliding with the guide groove 4 quickly, which makes the valve head 7 easily wear and deform, and can increase the service life of the valve head 7.

[0019] Specifically, the diameter of the first through groove 2 is smaller than the diameter of the second through groove 3, and the guide groove 4 is inclined outward from the first through groove 2 to the second through groove 3, wherein a mounting plate 13 is provided in the second through groove 3, the valve cylinder 8 is slidably connected to the center of the mounting plate 13, and a plurality of the guide grooves 10 are provided around one end of the valve cylinder 8 close to the valve head 7, the limit seat 9 is between the valve head 7 and the mounting plate 13, and the distance between the limit seat 9 and the slide groove 5 is less than the length of the slide rod 12, as shown in FIG. Figures 1 to 4 As shown, when the fluid enters from the second through groove 3 , the fluid is blocked by the mounting plate 13 and enters the valve cylinder 8 . After entering the valve cylinder 8 , the fluid impacts the valve head 7 and drives the valve head 7 to move toward the guide groove 4 .

[0020] Furthermore, a pressure rod 14 is slidably connected to the limit seat 9, and a push plate 15 is provided at one end of the pressure rod 14 facing the valve head 7, and the push plate 15 is connected to the limit seat 9 through a telescopic spring 16. Figures 1 to 4 As shown, when the fluid enters from the first through groove 2, the fluid drives the valve head 7 to move toward the limit seat 9, and the valve head 7 is abutted against the push plate 15 on the limit seat 9. The push plate 15 drives the pressure rod 14 to move and compresses the telescopic spring 16. The telescopic spring 16 can slow down the movement speed of the valve head 7 to prevent the valve head 7 from directly colliding with the limit seat 9, and the limit seat 9 can limit the movement stroke of the valve head 7 to prevent the slide rod 12 from falling off the slide groove 5 when the valve head 7 is separated from the guide groove 4.

[0021] Furthermore, the valve head 7 is a truncated cone structure, the retaining ring 11 is arranged on the side where the valve head 7 is connected to the valve cylinder 8, and the plurality of slide rods 12 are evenly arranged on the retaining ring 11. A buffer pad 17 is provided in the guide groove 4, and a sealing ring 18 is provided between the slide groove 5 and the guide groove 4 on the side of the second through groove 3 close to the first through groove 2. Figures 1 to 4 As shown, the retaining ring 11 can be extended backward around the side facing away from the slide rod 12, so that when the fluid enters the valve cylinder 8 from the second through groove 3, the fluid can flow out of the valve cylinder 8 from the guide groove 10. In this way, the extended part of the retaining ring 11 can block the fluid and reduce the fluid from entering the guide groove 4 from the second through groove 3. When the valve head 7 and the guide groove 4 are against each other, the buffer pad 17 on the guide groove 4 can reduce the impact between the valve head 7 and the guide groove 4, and play a role in protecting the valve head 7. The buffer pad 17 can be a rubber pad. In addition, the sealing ring 18 can seal the gap between the valve core and the guide groove 4 with the buffer pad 17, and improve the sealing effect of the valve core and the backflow cut-off effect.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
