Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a valve and an air conditioner. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. They have functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion, or overflow pressure relief. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. They are widely used in life. For example, the refrigerant shut-off valve on the air conditioner is used to control the flow of refrigerant and plays a vital role in the air conditioner. Due to the complex internal structure of the refrigerant shut-off valve and the many edges and corners, the refrigerant flows through the inside of the refrigerant shut-off valve, and the high-speed refrigerant collides with the edges and corners of the internal structure, and the gas bubble flow breaks to produce refrigerant sound. The refrigerant sound is transmitted to the room with the refrigerant, which will give users a bad user experience. Utility Model Content

[0044] Figure 1 is a schematic partial structural diagram of a valve according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 6 The embodiment of the utility model provides a valve, including a valve body 120 and a valve core 110. The valve body 120 has a delivery channel 121 and an installation cavity 122, and a valve core opening connected to the installation cavity 122 is provided on the delivery channel 121. The delivery channel 121 includes a first channel 1211 and a second channel 1212 located on both sides of the valve core opening, and the first channel 1211 and the second channel 1212 are cross-arranged. The valve core 110 is slidably arranged in the installation cavity 122 to enter the delivery channel 121 through the valve core opening, and then disconnect the delivery channel 121. The inner end of the valve core 110 is provided with a mating surface 111, and the mating surface 111 is configured to be at the valve core opening when the valve is fully opened, so that the wall surface of the first channel 1211 and the wall surface of the second channel 1212 are smoothly transitioned through the mating surface 111.

[0045] In a valve of an embodiment of the utility model, when the valve is fully opened, the valve core 110 is located in the installation cavity 122, and the matching surface 111 of the valve core 110 is located at the valve core opening to block the valve core opening, and a smooth spherical surface is formed at the opening of the valve core 110. Since the valve core opening is at the intersection of the first channel 1211 and the second channel 1212, the matching surface 111 can make the intersection of the first channel 1211 and the second channel 1212 smoothly transition. When the liquid in one of the first channel 1211 and the second channel 1212 is transported to the other channel, the matching surface 111 can use its curvature to drain the liquid, reducing the impact of the liquid on the inner wall of the circulation channel, that is, when the delivery channel 121 transports the liquid, the setting of the matching surface 111 plays a role in reducing noise, thereby improving the user experience.

[0046] When the valve is closed, the inner end of the valve core 110, that is, a section provided with the mating surface 111, enters the delivery channel 121 through the valve core opening, and blocks the delivery channel 121 at the intersection of the first channel 1211 and the second channel 1212, so that the first channel 1211 is not connected to the second channel 1212, and further the liquid in one of the first channel 1211 and the second channel 1212 is unequally delivered to the other channel.

[0047] Furthermore, it can be seen from the above that when the valve is fully opened, the matching surface 111 blocks the valve core opening, so that the delivery channel 121 will not overflow through the valve core opening when delivering liquid, thereby ensuring the delivery efficiency.

[0048] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, the angle between the axis of the first channel 1211 and the axis of the second channel 1212 is a right angle. The above-mentioned matching surface 111 reduces the angle between the first channel 1211 and the second channel 1212.

[0049] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the installation cavity 122 includes a first cavity and a second cavity. The outer end of the first cavity is connected to the outside, and the inner end of the first cavity is connected to the delivery channel 121 through the second cavity. The first cavity and the second cavity are coaxial. The valve core 110 is slidably disposed in the first cavity and the second cavity, and the valve core 110 always blocks the second cavity.

[0050] In this embodiment, the valve core 110 enters the first cavity through one end of the first cavity connected to the outside, and then enters the second cavity connected to the first cavity. It can be seen from the above embodiment that the installation cavity 122 is connected to the delivery channel 121 through the valve core opening, and the matching surface 111 of the valve core 110 blocks the valve core opening, or enters the delivery channel 121 to block the delivery channel 121. That is, the second cavity is connected to the delivery channel 121 through the valve core opening. And the valve core 110 always blocks the second cavity, that is, whether the inner end of the valve core 110 is at the valve core opening or in the delivery channel 121, the inner surface of the second cavity is always in contact with the outer surface of the valve core 110, which ensures that the liquid in the delivery channel 121 will not enter the second cavity whether the valve is opened or closed, and further ensures that the liquid will not overflow.

[0051] Furthermore, the first cavity and the second cavity are coaxially arranged, so that the valve core 110 can slide more smoothly.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the installation cavity 122 is coaxial with the first channel 1211. The valve core 110 includes a cylindrical section and a protrusion disposed at the inner end of the cylindrical section, and one side of the protrusion is a mating surface 111. When the valve core 110 moves inward, the other side of the protrusion contacts and abuts against the wall of the first channel 1211.

[0053] In this embodiment, when the valve is closed, the valve core 110 slides toward the first channel 1211 through the valve core opening. Since the installation cavity 122 is coaxial with the first channel 1211, the inner end of the valve core 110 directly blocks the port of the first channel 1211, so that the liquid in the delivery channel 121 cannot continue to flow. In addition, the coaxial installation cavity 122 and the first channel 1211 make the valve core 110 slide more smoothly.

[0054] In addition, the raised surface facing the valve core 110 is the mating surface 111, that is, the mating surface 111 is a gentle curved surface. During the process of conveying liquid in the conveying channel 121, the curved surface can effectively guide the liquid, thereby reducing the force of the liquid hitting the inner wall of the conveying channel 121 and preventing the liquid from overflowing.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the plane where the axis of the first channel 1211 and the axis of the second channel 1212 are located is the reference plane. The intersection line between the matching surface 111 and the reference plane is the first arc line. The intersection line between the delivery channel 121 and the reference plane includes a second arc line, which is directly opposite to the valve core opening, and the center of the second arc line is at the same position as the center of the first arc line.

[0056] In this embodiment, since the intersection line between the delivery channel 121 and the reference plane and the intersection line between the matching surface 111 and the reference plane are both arc lines, that is, the intersection surface between the first channel 1211 and the second channel 1212 is very smooth. During the flow of liquid, the liquid smoothly enters the other channel from one channel between the first channel 1211 and the second channel 1212, further reducing the force of the liquid hitting the inner wall of the delivery channel 121, achieving a better noise reduction effect.

[0057] Furthermore, in this embodiment, the centers of the second arc line and the first arc line are at the same position, which makes the shape of the connecting channel beautiful.

[0058] In some embodiments of the present invention, Figure 1 and Figure 2As shown, at least one first groove 112 is provided on the outer surface of the valve core 110, and the first groove 112 extends along the circumferential direction of the valve core 110. A first sealing ring 130 is provided in the first groove 112, and the first sealing ring 130 is close to the inner wall of the first cavity. A second groove 1221 is provided on the inner surface of the first cavity, and the second groove 1221 extends along the circumferential direction of the first cavity. A second sealing ring 140 is provided in the second groove 1221, and the second sealing ring 140 is close to the outer end of the valve core 110.

[0059] In this embodiment, when the valve core 110 slides in the first cavity and the second cavity, the first groove 112 provided on the valve core 110 will also slide along with the valve core 110, and of course the first sealing ring 130 will also follow the first groove 112 and slide synchronously in contact with the inner wall surface of the first cavity. Since the first groove 112 surrounds the valve core 110 in the circumferential direction of the valve core 110, that is, the first sealing ring 130 also surrounds the valve core 110 and in contact with the inner wall surface of the first cavity, the water in the communication channel will not flow outward through the first cavity, further ensuring the sealing of the valve.

[0060] Furthermore, in this embodiment, when the valve core 110 slides to the position where the valve is fully opened, the outer end of the valve core 110 is disposed against the second sealing ring 140 in the second groove 1221. Since the second groove 1221 surrounds the inner wall of the first cavity in the circumferential direction, the position of the valve core 110 is limited and the sealing performance is further improved.

[0061] The setting of the second sealing ring 140 and the setting of the first sealing ring 130 and the second sealing ring 140 can prevent the inner wall surface of the first cavity from contacting the valve core 110. During the sliding process of the valve core 110, the problem of shortening the life of the valve due to wear is reduced, and the service life of the valve is effectively improved.

[0062] In this embodiment, the second groove 1221 is always located outside the first groove 112 .

[0063] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the longitudinal section of the first sealing ring 130 is larger than the longitudinal section of the second sealing ring 140. From the above embodiment, it can be seen that the first sealing ring 130 is located below the second sealing ring 140, that is, the second sealing ring is closer to the conveying channel 121, and the larger first sealing ring 130 has better sealing performance.

[0064] In some embodiments of the present invention, Figures 1 to 6 As shown, the valve further includes an adjusting nut 150 , which is disposed on the valve body 120 , and the adjusting nut 150 is rotatably connected to the valve core 110 .

[0065] In this embodiment, when the valve needs to be opened or closed, it is only necessary to adjust the adjusting nut 150 so that the adjusting nut 150 drives the valve core 110 to slide inside the installation cavity 122. The operation is very simple. In addition, the adjusting nut 150 is rotatably connected to the valve core 110, so the adjusting nut 150 does not drive the valve core 110 to rotate when rotating.

[0066] In some embodiments of the present invention, the valve further includes an adjusting nut 150. The adjusting nut 150 abuts against the outer end of the valve core 110. The valve further includes a return spring, which is disposed in the mounting cavity 122 and configured to cause the valve core 110 to move toward the adjusting nut 150.

[0067] In this embodiment, when the valve needs to be closed, the adjusting nut 150 is operated to press the valve core 110 against which it abuts toward the delivery channel 121, so that the valve core 110 slides until the valve is closed. When the valve needs to be opened, the adjusting nut 150 is operated to move outwards. At this time, there is no resistance at the outer end of the valve core 110, and the return spring in the installation cavity 122 drives the valve core 110 to slide outwards until the matching surface 111 is at the valve core opening. The adjusting nut 150 is stopped, and the valve is fully opened.

[0068] It should be noted here that the valve is a normally open valve, so the return spring in the installation cavity 122 is in a relaxed state in most cases, which can extend the service life of the return spring and further extend the service life of the valve.

[0069] In some embodiments of the present invention, the inner surface of the installation cavity 122 is provided with a slide groove, which extends along the sliding direction of the valve core 110. The outer surface of the valve core 110 is provided with a bump, which is arranged in the slide groove and configured to slide along the length direction of the slide groove.

[0070] In this embodiment, when the valve core 110 slides in the installation cavity 122, the protrusion on the valve core 110 slides along the slide groove. Since the slide groove extends along the sliding direction of the valve core 110, that is, the slide groove extends along the length direction of the installation cavity 122, the valve core 110 will not rotate during the sliding process, thereby ensuring the sealing of the valve.

[0071] In some embodiments of the present invention, Figures 1 to 6 As shown, the valve further includes a connecting pipe 170, a first plug 180, a second plug 160 and at least two ear plates 190. One end of the connecting pipe 170 is inserted into the first channel 1211. The first plug 180 blocks the other end of the connecting pipe 170. The second plug 160 blocks the outer end of the second channel 1212. Each ear plate 190 is connected to the valve body 120 at the outer end of the first channel 1211.

[0072] In this embodiment, the liquid in the connecting tube 170 can enter the second channel 1212 through the first channel 1211. Since the connecting tube 170 is inserted into the first channel 1211, that is, the diameter of the connecting tube 170 is smaller than the diameter of the first channel 1211, liquid leakage is avoided during the liquid transportation process.

[0073] The first plug 180 and the second plug 160 protect the exposed ports of the connecting pipe 170 and the second channel 1212, thereby preventing the ports of the connecting pipe 170 and the second channel 1212 from being damaged by external forces.

[0074] like Figure 5 As shown, the arrangement of the ear plate 190 facilitates the installation and fixation of the valve, and further makes the valve more stable when conveying liquid.

[0075] In some embodiments of the present invention, the ear plate 190 is provided with a threaded hole.

[0076] In some embodiments of the present invention, the valve is a refrigerant stop valve, which is used to transmit the refrigerant. The refrigerant enters from the first channel 1211 and flows out from the second channel 1212.

[0077] In some embodiments of the present invention, the connecting pipe 170 is a copper connecting pipe.

[0078] In this embodiment, the copper pipe is a high-quality copper material with good electrical conductivity, thermal conductivity, corrosion resistance and machinability. It also has high thermal conductivity and high strength, can withstand high pressure and high temperature, and can maintain a typical bent shape at low temperatures, making it an ideal choice for manufacturing cooling systems.

[0079] In some embodiments of the present invention, the connecting pipe 170 is a straight pipe.

[0080] In some embodiments of the present invention, the connecting pipe 170 is a right-angle single-bend pipe.

[0081] In some embodiments of the present invention, the connecting pipe 170 is a right-angle double-bend pipe.

[0082] The embodiment of the utility model provides an air conditioner, comprising an outdoor unit body and a valve in any of the above embodiments. The ear plate 190 of the valve is screwed to the outdoor unit body.

[0083] In this embodiment, the valve is screwed to the outdoor unit body through the threaded holes on the ear plate 190. The screw connection makes the valve more firmly installed on the outdoor unit body, and the screw connection is more flexible, convenient for disassembly and installation, and provides convenience for subsequent maintenance work.

[0084] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
