DETAILED DESCRIPTION OF THE INVENTION

[0010] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. It is clear that the described embodiments are only a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without any creative work shall fall within the protection scope of the present disclosure.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only, and should not be understood as indicating or implying relative importance.

[0012] It should be noted that in the description of the present disclosure, unless otherwise specified and limited, the terms "attach," "connect to each other," and "connect" should be understood in a broad sense. For example, they may be fixedly connected, detachably connected, or integrally connected. They may be mechanically connected or electrically connected. They may be directly connected to each other, indirectly connected to each other via an intermediate member, or may be in internal communication between the two elements. Those skilled in the art can understand the specific meanings of the above terms in the present disclosure depending on the specific circumstances.

[0013] The present disclosure provides a slider assembly, a valve, and an air conditioning system to alleviate a technical problem existing in the prior art in that the slider in a conventional valve blocks fluid from flowing in through an inlet, resulting in reduced flow rate.

[0014] As shown in Figures 1 to 10, this embodiment includes a valve body 101 and a valve core, the valve body 101 is provided with an inlet 102, the valve core is located inside the valve body 101 and includes a slider 103, the slider 103 is provided with a protrusion 104 on the side closer to the inlet 102, the slider 103 is movable relative to the valve body 101 so that the protrusion 104 seals or opens the inlet 102, and the protrusion 104 has at least one notch on its circumferential edge, and the notch provides a valve that is positioned so that the protrusion 104 avoids the inlet 102 when the inlet 102 is in an open state.

[0015] The valve provided by this embodiment has a protrusion 104 on the side of the slider 103 closer to the inlet 102, so that when the slider 103 moves relative to the valve body 101, the protrusion 104 can seal or open the inlet 102; at least one notch is provided on the circumferential edge of the protrusion 104, so that when the protrusion 104 is located on one side of the inlet 102, the protrusion 104 can avoid the inlet 102, that is, the protrusion 104 does not block the inlet 102, so it does not prevent fluid from entering through the inlet 102 and ensures that the flow rate is not reduced.

[0016] Depending on the application of the valve, the fluid entering the inlet 102 may be a gas, a liquid, or a mixed gas-liquid medium.

[0017] The valve provided by this embodiment may be a one-way valve or a multi-way valve, and as shown in Figures 2, 4 and 5, for example, the slider 103 moves relative to the valve body 101, and when the slider 103 and the protrusion 104 are positioned below the inlet 102, the inlet 102 is sealed by the protrusion 104, and when the slider 103 and the protrusion 104 are positioned on one side (e.g., the left or right side) of the inlet 102, the inlet 102 is in an open state.

[0018] In some embodiments, as shown in Figures 1 and 4, the valve core includes a guide frame 109 and a slider assembly, and the slider assembly includes a slider 103 and a protrusion 104, for example, the slider 103 and the protrusion 104 are integrally molded, and communication ports 110 are provided at both ends of the guide frame 109, respectively, and the slider 103 is attached between both ends of the guide frame 109, and the slider 103 moves by moving the guide frame 109 so that the inlet 102 communicates with one of the communication ports 110.

[0019] There is a chamber inside the valve element 101, and end covers are provided on both ends of the valve element 101 so that the chamber of the valve element 101 forms a relatively closed cavity. The chamber of the valve element 101 is a cylindrical cavity, and the slider 103 can reciprocate along the axis of the chamber of the valve element 101 to realize the opening and closing and direction switching of the valve.

[0020] In one embodiment, the inlet 102 is a circular hole drilled in the side wall of the valve body 101, and the corresponding notch is an arcuate notch that aligns with the edge of the circular hole.

[0021] It should be noted that if the inlet 102 is a hole of another shape, the shape of the notch will match the contour of the edge of the inlet 102 that it is adjacent to, so as to achieve the avoidance objective.

[0022] In one embodiment, as shown in FIG. 3, the valve further includes a connecting pipe 107. The connecting pipe 107 communicates with the inlet 102. One end of the connecting pipe 107 is located inside the inlet 102. When the radius of the arc-shaped notch is r1, r1>0.5d1, where d1 is the outer diameter of the connecting pipe 107.

[0023] For example, the outer wall of the connecting pipe 107 is welded to the edge of the inlet 102. By the method that the radius r1 of the arc-shaped notch is greater than 0.5d1, it can be ensured that the protrusion 104 does not function as a throttle for the fluid entering from the connecting pipe 107. When the valve is in the cooling or heating state applied to the air conditioning system, the slider 103 will not affect the medium flow capacity on the high-pressure side.

[0024] In one embodiment, the valve body 101 has a hollow cylindrical structure. The inlet 102 is located on the circumferential side wall of the valve body 101. As shown in FIGS. 9 and 10, the surface of the protrusion 104 facing the inlet 102 is an arc surface that conforms to the inner surface of the valve body 101. Since the inlet 102 is located on the circumferential side wall of the valve body 101 and the end face of the inlet 102 forms an arc surface, the surface of the protrusion 104 facing the inlet 102 becomes an arc surface that conforms to the inner surface of the valve body 101, ensuring that the protrusion 104 and the end face of the inlet 102 are aligned. It is advantageous to reduce the radial distance between the protrusion 104 and the end face of the inlet 102 to improve the sealing effect of the protrusion 104 on the inlet 102. After the valve is closed, the pressure inside the valve body 101 can be significantly reduced.

[0025] In one embodiment, as shown in FIG. 3, when the radial distance between the surface of the protrusion 104 facing the inlet 102 and the inner surface of the valve body 101 is t, 0<t≦0.45 cm. By controlling the radial distance between the surface of the protrusion 104 facing the inlet 102 and the inner surface of the valve body 101 within 0.45 cm, the sealing effect on the inlet 102 can be effectively improved. For example, the sealing effect can be improved by more than 50%.

[0026] Illustratively, the radial distance t between the surface of the protrusion 104 facing the inlet 102 and the inner surface of the valve body 101 is 0.005 cm, 0.008 cm, 0.01 cm, 0.02 cm, 0.03 cm, 0.04 cm, 0.05 cm, 0.06 cm, 0.07 cm, 0.08 cm, 0.1 cm, 0.12 cm, 0.14 cm, 0.15 cm, 0.16 cm, 0.18 cm, 0.2 cm , 0.22cm, 0.24cm, 0.26cm, 0.28cm, 0.3cm, 0.32cm, 0.34cm, 0.36cm, 0.38cm, 0.4cm, 0.41cm, 0.42cm, 0.43cm, 0.44cm, 0.441cm, 0.442cm, 0.443cm, 0.445cm, 0.447cm or 0.45cm.

[0027] In one embodiment, the valve is a four-way valve.

[0028] In one embodiment, the number of notches is two, and the two notches are provided opposite each other along the radial direction of the protrusion 104 .

[0029] Specifically, the two notches are named a first notch 105 and a second notch 106, respectively, and the first notch 105 and the second notch 106 are provided at both radial ends of the protrusion 104 that are parallel to the axis of the valve body 101.

[0030] When the slider 103 is located on either side of the entrance 102, any of the notches at the corresponding positions can achieve the purpose of avoiding the entrance 102.

[0031] In one embodiment, as shown in Fig. 3, a flange 108 is provided at the inlet 102 of the valve disc 101, and a fillet is provided between the flange 108 and the valve disc 101. As shown in Figs. 3 and 7, if the distance between the two notches is d2, then d2 > d1 + 2r2, where d1 is the outer diameter of the connecting pipe 107 and r2 is the radius of the fillet. As shown in Fig. 7, the distance between the two notches refers to the shortest distance between the first notch 105 and the second notch 106. If the first notch 105 and the second notch 106 are both arc-shaped notches, the shortest distance between the first notch 105 and the second notch 106 is the distance between the vertices of the arc-shaped edges of the two arc-shaped notches.

[0032] Illustratively, the outer surface of the protrusion 104 is a cylindrical surface, for example, a circular cylinder, with a notch, but the outer surface of the protrusion 104 may have other shapes as long as the protrusion 104 can seal the inlet 102 during the movement of the slider 103. For example, a plurality of flat surfaces may be connected end to end, with the notch on the flat surface, or an annular curved surface may be formed with the notch on the annular curved surface.

[0033] For example, the flange 108 is located outside the valve body 101, and in this manner, the gap between the protrusion 104 and the valve body 101 is reduced, i.e., the flange 108 is prevented from being located inside the valve body 101 and occupying the internal space of the valve body 101.

[0034] Because the distance between the two notches is d2>d1+2r2, when the slider 103 is positioned directly below the inlet 102, the protrusion 104 can completely cover the inlet 102, effectively preventing fluid from flowing into the valve body 101 and improving the sealing effect.

[0035] It should be noted that one end of the connecting pipe 107 may be fitted to the outside of the flange 108 .

[0036] In one embodiment, as shown in Figures 1 and 2, the valve body 101 is provided with a first connection port 111, a second connection port 112, and a third connection port 113, the second connection port 112 facing the inlet 102 and located between the first connection port 111 and the third connection port 113, the protrusion 104 can be located on the side of the inlet 102 closer to the first connection port 111 so that the inlet 102 and the third connection port 113 are in communication with each other, with a notch adjacent to the third connection port 113 aligned with the circumferential edge of the inlet 102, and the protrusion 104 can also be located on the side of the inlet 102 closer to the third connection port 113 so that the inlet 102 and the first connection port 111 are in communication with each other, with a notch adjacent to the first connection port 111 aligned with the circumferential edge of the inlet 102.

[0037] Specifically, the first connection port 111, the third connection port 113, and the second connection port 112 are located on the same side of the valve body 101. Pipelines are connected to the first connection port 111, the second connection port 112, and the third connection port 113, respectively.

[0038] When the slider 103 moves to the position shown in Figure 4, the protrusion 104 is located on the side of the inlet 102 closer to the first connection port 111 so that the inlet 102 and the third connection port 113 are connected, and here the second notch 106 is located outside the circumferential edge of the inlet 102, i.e., the second notch 106 avoids the fluid flowing in from the inlet 102, and the protrusion 104 does not throttle the fluid.

[0039] When the slider 103 moves to the position shown in Figure 5, the protrusion 104 is located on the side of the inlet 102 closer to the third connection port 113 so that the inlet 102 and the first connection port 111 are connected, and here the first notch 105 is located outside the circumferential edge of the inlet 102, i.e., the first notch 105 avoids the fluid flowing in from the inlet 102, and the protrusion 104 does not throttle the fluid.

[0040] This embodiment further provides a slider assembly that is slidably mounted within the valve body to seal or open the inlet of the valve body. As shown in Figures 6 to 10, the slider assembly includes a slider 103 and a protrusion 104. The protrusion 104 is connected to the slider 103 and can seal or open the inlet of the valve body. The protrusion 104 has at least one notch on its circumferential edge, which is used for the protrusion 104 to avoid the inlet of the valve body when the inlet of the valve body is in an open state.

[0041] The slider assembly provided by this embodiment can be applied to the valve provided by this embodiment, and the notch is used to allow the protrusion 104 to avoid the inlet 102 of the valve body 101 when the inlet 102 of the valve body 101 is in an open state.

[0042] It should be noted that the slider assembly provided by this embodiment can also be applied to conventional valves.

[0043] Illustratively, the notches are arcuate notches, the number of the arcuate notches is two, and the two arcuate notches are provided back to back.

[0044] In some embodiments, a recessed chamber 114 is provided on the side of the slider 103 away from the protrusion 104, and for example, when the slider assembly is positioned on the side closer to the first connection port 111 of the inlet 102, the inlet 102 and the third connection port 113 are connected, and the second connection port 112 and the first connection port 111 are connected via the recessed chamber 114.

[0045] The present embodiment further provides an air conditioning system including the valve provided by the present embodiment.

[0046] The air conditioning system provided by this embodiment uses the valve provided by this embodiment, so when the protrusion 104 is located on one side of the inlet 102, the protrusion 104 can avoid the inlet 102, that is, the protrusion 104 does not block the inlet 102, so the fluid is not prevented from entering through the inlet 102, the flow rate is not reduced, and the cooling effect is further improved.

[0047] Furthermore, when the slider 103 moves directly below the inlet 102, the protrusion 104 can effectively seal the inlet 102, significantly reducing the pressure inside the valve body 101 and improving the safety of the system.

[0048] It should be noted that the air conditioning system further includes structures such as a compressor, an evaporator, and a condenser, but the connection relationship thereof and the working principles of cooling and heating are conventional technologies, so detailed description thereof will be omitted here.

[0049] Finally, it should be explained that the above embodiments are merely for explaining the technical aspects of the present disclosure, and are not intended to limit the same. Having described the present disclosure in detail with reference to the above embodiments, those skilled in the art may modify the technical aspects described in the above embodiments or substitute some or all of the technical features therein with equivalents, and it should be understood that these modifications or substitutions do not cause the essence of the corresponding technical aspects to deviate from the scope of the technical aspects of the embodiments of the present disclosure.
