Description

Technical Field

[0001] The utility model belongs to the technical field related to air-conditioning equipment, and particularly relates to an air-conditioning stop valve and an air-conditioning. Background Art

[0002] The air conditioning stop valve is an important component of the air conditioner and is used to control the on / off of the refrigerant in the air conditioning passage.

[0003] Among them, when the throttled low-temperature refrigerant flows through the inside of the air-conditioning stop valve, condensed water will be generated on the outside of the valve body of the air-conditioning stop valve due to condensation, causing water to accumulate in the connecting cover part of the air-conditioning stop valve that is threadedly connected to the valve body. In this way, when the air-conditioning outdoor unit (the stop valve is arranged on the air-conditioning outdoor unit) is working in an environment with an outside temperature below zero, the condensed water will expand in volume due to freezing, thereby causing the connecting cover position of the air-conditioning stop valve to be at risk of rupture.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0046] like Figure 1 As shown, an air conditioning stop valve 100 provided in an embodiment of the present application includes a valve body 10 and a connection cover 20, wherein the connection cover 20 is connected to the valve tube 11 of the valve body 10 in a threaded manner; wherein a drainage hole 21 is provided on the connection cover 20, and the drainage hole 21 is provided on a threaded connection portion of the connection cover 20 for threaded connection with the valve tube 11, and condensed water generated by the valve body 10 at the position of the valve tube 11 can be discharged through the drainage hole 21. It should be noted that the other structural components of the above-mentioned valve body 10 and the principle of how to generate condensed water at the position of the valve tube 11 during operation are conventional methods of existing air conditioning stop valves, and will not be elaborated here.

[0047] It can be understood that the air-conditioning stop valve 100 can use the drainage hole 21 to discharge condensed water. In this way, when the air-conditioning stop valve 100 is used in an air-conditioning and works in an environment with an outside temperature below zero, the condensed water generated by the air-conditioning stop valve 100 at the position of the valve tube 11 corresponding to the connecting cover 20 will freeze. The excess condensed water can be discharged to the outside through the drainage hole 21 on the connecting cover 20. In this way, the air-conditioning stop valve 100 can be prevented from breaking the connecting cover 20 due to the expansion of the volume of the frozen condensed water.

[0048] like Figure 1 As shown, the connection cover 20 of the present application includes a cap 201, a connecting nut 202 and / or a valve cap 203. That is to say, the air conditioning stop valve 100 of the present application can be provided with a drainage hole 21 on the cap 201, the connecting nut 202 and / or the valve cap 203 according to the use requirements. Preferably, the drainage holes 21 are respectively provided on the cap 201, the connecting nut 202 and the valve cap 203 to prevent the cap 201, the connecting nut 202 and the valve cap 203 from being ruptured when they are assembled on the valve body 10 corresponding to the valve tube 11.

[0050] It should be noted that there are multiple side end faces 22 on the connection cover 20, and the multiple side end faces 22 are connected end to end and together form the outer peripheral surface 221 of the connection cover 20, that is, the cross section of the connection cover 20 is polygonal; wherein, the number of drainage holes 21 arranged on at least one side end face 22 is set to S, wherein S ≥ 1. Each drainage hole 21 can be used to discharge condensed water outward, so that at least one drainage hole 21 is opened on at least one side end face 22 of the connection cover 20, so that the drainage efficiency of the drainage hole 21 when discharging condensed water generated at the position of the valve tube 11 on the valve body 10 can be improved.

This is because according to the aperture of the drain hole 21 to be processed, a tool with a certain thickness can be used for processing to ensure the structural strength of the corresponding tool. Here, the drain hole 21 is set as a circular through hole. Of course, in other embodiments, the cross section of the drain hole 21 can also be set to other shapes according to the use requirements, such as rectangle, triangle, prism or other irregular shapes, which will not be elaborated here.

[0052] like Figure 2 As shown, in one embodiment, the connection cover 20 further has a bottom end surface 23, which is disposed in the area where the corresponding valve tube 11 is located; the maximum distance between the bottom end surface 23 and the side end surface 22 is set to H, the distance between the bottom end surface 23 and the center line of the drain hole 21 is set to H1, and the aperture of the drain hole 21 is set to D, wherein HD / 2

In other words, for valve bodies 10 of different sizes, the valve cap 203 can be matched with different threaded holes 30, and the valve cap 203 can be assembled with the corresponding valve tube 11 on the valve body 10, so that the valve cap 203 can be adapted to valve bodies 10 of different sizes, that is, the valve cap 203 can be applied to air conditioning stop valves 100 of different specifications, thereby reducing costs.

[0054] It should be noted that a drainage hole 21 may be opened at the position where any threaded hole 30 of the valve cap 203 is located, so that when the valve cap 203 is assembled on the valve body 10, condensed water generated on the valve body 10 at the position of the valve tube 11 corresponding to the valve cap 203 can be discharged through the drainage hole 21.

[0055] like Figure 6 As shown, in this embodiment, the threaded hole 30 includes a first threaded hole 31 and a second threaded hole 32.

Here, the thread of the first threaded hole 31 and / or the thread of the second threaded hole 32 can be a 7 / 16-20UNF thread or a 1 / 2-20UNF thread.

[0056] like Figure 6 As shown, in this embodiment, the valve cap 203 has a partition 2031, which is used to partition the first threaded hole 31 and the second threaded hole 32, that is, the bottom of the first threaded hole 31 and the bottom of the second threaded hole 32 are both arranged on the partition 2031; wherein, the wall thickness of the partition 2031 is set to D1, D1 ≥ 1mm; in addition, the wall thickness of the valve cap 203 in the area where the first threaded hole 31 is located is set to D2, D2 ≥ 1mm, and the wall thickness of the valve cap 203 in the area where the second threaded hole 32 is located is set to D3, D3 ≥ 1mm, so that the overall structural strength of the valve cap 203 can be ensured. It should be noted that the height of the valve cap 203 is set to G, wherein G is equal to 25.4mm, so that the first threaded hole 31 and the second threaded hole 32 on the valve cap 203 can be used for the assembly of the corresponding valve pipe 11 on the valve body 10 respectively. Here, the valve cap 203 is provided with drainage holes 21 at the location of the first threaded hole 31 and the location of the second threaded hole 32 .

[0057] like Figure 5 , Figure 6 As shown, in one embodiment, a holding surface 2032 is formed on the outer peripheral wall 2030 of the valve cap 203, and the holding surface 2032 can be held by a hexagonal wrench (not shown), and the valve cap 203 can be rotated relative to the valve body 10 under the drive of the hexagonal wrench. In other words, the air conditioning stop valve 100 of this embodiment can use a hexagonal wrench to drive the valve cap 203 to rotate relative to the valve body 10, and realize the disassembly and assembly of the valve cap 203 on the corresponding valve tube 11 on the valve body 10. It should be noted that when the valve cap 203 has the first threaded hole 31 and the second threaded hole 32, since the height of the valve cap 203 is increased, it is convenient to drive the valve cap 203 to rotate with the hexagonal wrench.

[0058] like Figure 7 As shown, in this embodiment, when a holding surface 2032 for holding with a hexagonal wrench is formed on the outer peripheral wall 2030 of the valve cap 203, the distance between the two symmetrical holding surfaces 2032 on the valve cap 203 is set to L, wherein L≥16 mm.

[0059] like Figure 8 , Fig. 9 As shown, in one embodiment, a knurled surface 2033 is provided on the outer peripheral wall 2030 of the valve cap 203, and the knurled surface 2033 can be held by a human hand, and the valve cap 203 can be rotated relative to the valve body 10 under the drive of the human hand.

It should be noted that when the valve cap 203 has the first threaded hole 31 and the second threaded hole 32, the height of the valve cap 203 is increased, so that the length of the knurled surface 2033 on the valve cap 203 can also be increased, so that it is convenient for a human hand to hold the knurled surface 2033 on the valve cap 203, and it is convenient to drive the valve cap 203 to rotate relative to the valve body 10.

[0060] In addition, the present application also provides an air conditioner, including an air conditioner main body (not shown) and the air conditioner stop valve 100 described above, wherein the air conditioner stop valve 100 is installed on the air conditioner main body; wherein at least one drainage hole 21 is arranged at the bottom direction of the air conditioner stop valve 100, so that the condensed water can be discharged from the corresponding drainage hole 21 by utilizing the gravity of the condensed water itself.
