Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a valve core, a valve and a faucet. Background Art

[0002] At present, there are two types of sealing rings used for faucet valve cores on the market: one-piece sealing rings and separate sealing rings.

[0003] Because one-piece sealing rings are connected by a common sealing portion, they allow the inner diameters of the valve core's first and second water inlets, as well as its outlet, to be designed to be relatively large, given a given valve core diameter. This increases the valve core's inlet and outlet flow rates. However, because each common sealing portion simultaneously seals two adjacent outlets, the valve core's water pressure resistance is relatively weak. When water pressure reaches a certain level, the valve core is prone to leakage through the common sealing portion.

[0004] Since the separate sealing rings are designed to be independent of each other, this can increase the water pressure resistance to ensure the sealing performance. However, under the premise of a certain valve core diameter, the inner diameters of the first water inlet, second water inlet and water outlet of the valve core are designed to be relatively small, which affects the inlet and outlet flow of the valve core. Utility Model Content

[0005] In view of this, the purpose of this application is to overcome the deficiencies in the prior art and provide a valve core to solve the technical problems in the prior art of weak water pressure resistance of the one-piece sealing ring and small water inlet and outlet flow of the separate sealing ring.

[0006] To solve the above technical problems, this application provides:

[0007] A valve core, comprising:

[0008] A valve core body, wherein the valve core body is provided with a first water inlet, a second water inlet, and a water outlet, wherein the first water inlet, the second water inlet, and the water outlet are spaced apart from each other;

[0013] In some embodiments of the present application, the first groove and the second groove are arranged at intervals, and the first sealing part and the second sealing part are arranged at intervals.

[0014] In some embodiments of the present application, the interval between the first sealing part and the second sealing part is 0.8-1.2mm.

[0015] In some embodiments of the present application, the thickness of the sealing member is greater than the groove depth of the mounting groove.

[0037] As shown in Figure 1 and Figure 2 The embodiment of the present application provides a valve core 100, which is mainly applied to a valve. The valve core 100 is mainly applied to a faucet. The valve core 100 comprises a valve core body 110 and a sealing element 120.

[0038] Referring to Figure 3 and Figure 4The valve core body 110 is provided with a first water inlet 111, a second water inlet 112 and a water outlet 113, and the first water inlet 111, the second water inlet 112 and the water outlet 113 are spaced apart from each other.

[0039] The sealing member 120 includes a first sealing portion, a second sealing portion 122, a third sealing portion 123 and a connecting portion 124. The two ends of the third sealing portion 123 are respectively connected to the first sealing portion and the second sealing portion 122. The two ends of the connecting portion 124 are respectively connected to the first sealing portion and the second sealing portion 122. The first sealing portion is located on the outer circumference of the first water inlet 111, the second sealing portion 122 is located on the outer circumference of the second water inlet 112, and the third sealing portion 123 and the connecting portion 124 are both located on the outer circumference of the water outlet 113.

[0040] The valve core 100 provided in the embodiment of the present application connects the two ends of the third sealing part 123 to the first sealing part and the second sealing part 122 respectively, so that the third sealing part 123 is connected to the first sealing part and the second sealing part 122 through a common sealing part, so that the inner diameters of the first water inlet 111, the second water inlet 112 and the water outlet 113 can be designed to be relatively large, thereby facilitating increasing the inlet and outlet water flow of the valve core body 110.

[0041] At the same time, by connecting the ends of the connecting portion 124 to the first and second sealing portions 122, respectively, the first and second sealing portions 122 are made independent of each other, thereby increasing their resistance to water pressure and thereby improving sealing performance. This allows the seal 120 to achieve both a high inlet and outlet flow rate and water pressure resistance, ensuring both the inlet and outlet flow rate and sealing performance of the valve core body 110. This avoids the technical problems of prior art, such as the weak water pressure resistance of one-piece sealing rings and the low inlet and outlet flow rate of separate sealing rings.

[0042] like Figure 1 、 Figure 2 and Figure 4 As shown, in one embodiment of the present application, the valve core body 110 is provided with a mounting groove 114 that is adapted to the shape of the sealing member 120 .

[0043] In this embodiment, an installation groove 114 that is adapted to the outer shape of the seal 120 is opened on the valve core body 110, so that the seal 120 is limited to be displaced relative to the valve core body 110 under the limiting action of the installation groove 114, so that the first sealing portion, the second sealing portion 122 and the third sealing portion 123 of the seal 120 are stably maintained on the outer circumference of the first water inlet 111, the second water inlet 112 and the water outlet 113, respectively, thereby further ensuring the sealing performance.

[0044] like Figure 1 、 Figure 2 and Figure 4 As shown, in the above embodiment of the present application, the mounting groove 114 includes a first groove 1141, a second groove 1142, a third groove 1143 and a fourth groove 1144, the two ends of the third groove 1143 are respectively connected to the first groove 1141 and the second groove 1142, the two ends of the fourth groove 1144 are respectively connected to the first groove 1141 and the second groove 1142, the first sealing portion is arranged in the first groove 1141, the second sealing portion 122 is arranged in the second groove 1142, the third sealing portion 123 is arranged in the third groove 1143, and the connecting portion 124 is arranged in the fourth groove 1144.

[0045] In this embodiment, the two ends of the third groove 1143 are respectively connected to the first groove 1141 and the second groove 1142 to adapt to the outer shapes of the first sealing part, the second sealing part 122 and the third sealing part 123, so that the third sealing part 123, the first sealing part and the second sealing part 122, which are respectively connected to the first sealing part and the second sealing part 122 at both ends, can be respectively arranged in the third groove 1143, the first groove 1141 and the second groove 1142.

[0046] At the same time, by providing the fourth groove 1144 with both ends communicating with the first groove 1141 and the second groove 1142, respectively, to adapt to the shape of the connecting portion 124, the connecting portion 124 connected at both ends to the first sealing portion and the second sealing portion 122 can be disposed within the fourth groove 1144. Thus, the sealing member 120 is entirely disposed within the mounting groove 114.

[0047] like Figure 2 、 Figure 3 and Figure 4 As shown, in the above embodiment of the present application, the first groove 1141 and the second groove 1142 are spaced apart, and the first sealing portion and the second sealing portion 122 are spaced apart.

[0048] In this embodiment, the first sealing portion and the second sealing portion 122 are spaced apart so that the first sealing portion and the second sealing portion 122 are independent of each other, thereby increasing the water pressure resistance of the first sealing portion and the second sealing portion 122 and further improving the sealing performance of the seal 120.

[0049] At the same time, the first groove 1141 and the second groove 1142 are spaced apart to adapt to the outer shapes of the first sealing portion and the second sealing portion 122 spaced apart from each other.

[0050] In the above embodiment of the present application, the distance between the first sealing portion and the second sealing portion 122 is 0.8-1.2 mm.

[0051] In this embodiment, by controlling the spacing between the first and second sealing portions 122 to be between 0.8 mm and 1.2 mm, this can avoid, on the one hand, the technical problem of the spacing between the first and second sealing portions 122 being too small, thereby affecting the water pressure resistance of the first and second sealing portions 122. On the other hand, it can also avoid the technical problem of the spacing between the first and second sealing portions 122 being too large, thereby causing the inner diameters of the first and second water inlets 111 and 112 to be relatively reduced, thereby affecting the flow rate of water in and out of the valve core body 110.

[0052] For example, the distance between the first sealing portion and the second sealing portion 122 may be 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, etc., and may be specifically designed according to actual product needs.

[0053] In the above embodiment of the present application, the thickness of the sealing member 120 is greater than the depth of the mounting groove 114 .

[0054] In this embodiment, by setting the thickness of the sealing member 120 to be greater than the groove depth of the installation groove 114, when the sealing member 120 is set in the installation groove 114, the sealing member 120 partially protrudes from the installation groove 114, so that the sealing member 120 can contact the water pipe connector, thereby sealing the gap between the valve core 100 and the water pipe connector, and preventing water from leaking from the gap between the valve core 100 and the water pipe connector.

[0055] For example, in some embodiments of the present application, the first sealing portion, the second sealing portion 122 , the third sealing portion 123 and the connecting portion 124 are made of rubber material by integral injection molding.

[0056] In other embodiments, the first sealing portion, the second sealing portion 122 , the third sealing portion 123 and the connecting portion 124 are made of silicone material by integral injection molding.

[0057] The embodiment of the present application further provides a valve, comprising the valve core 100 described in the above embodiment.

[0058] The valve has the valve core 100 in any of the above embodiments, and thus has all the beneficial effects of the valve core 100, which will not be described in detail here.

[0059] An embodiment of the present application also provides a faucet, comprising the valve described in the above embodiment.

[0060] The faucet has the valve in the above embodiment, and thus has all the beneficial effects of the valve, which will not be described in detail here.

[0061] In summary, the present application proposes a valve core 100, a valve, and a faucet. The valve core 100 includes a valve core body 110 and a sealing member 120. The valve core body 110 is provided with a first water inlet 111, a second water inlet 112, and a water outlet 113 that are spaced apart from each other. The sealing member 120 includes a first sealing portion, a second sealing portion 122, a third sealing portion 123, and a connecting portion 124. By connecting the two ends of the third sealing portion 123 to the first sealing portion and the second sealing portion 122 respectively, the third sealing portion 123 is connected to the first sealing portion and the second sealing portion 122 through a common sealing portion, so that the inner diameters of the first water inlet 111, the second water inlet 112, and the water outlet 113 can be designed to be relatively large, thereby facilitating an increase in the inlet and outlet flow of the valve core body 110. At the same time, by connecting the ends of the connecting portion 124 to the first and second sealing portions 122, respectively, the first and second sealing portions 122 are made independent of each other, thereby increasing their resistance to water pressure and thereby improving sealing performance. This allows the seal 120 to achieve both a high inlet and outlet flow rate and water pressure resistance, ensuring both the inlet and outlet flow rate and sealing performance of the valve core body 110. This avoids the technical problems of prior art, such as the weak water pressure resistance of one-piece sealing rings and the low inlet and outlet flow rate of separate sealing rings.
