Description

Technical Field

[0001] The utility model belongs to the technical field of valve cores, and particularly relates to a side water inlet valve core. Background Art

[0002] The valve core is a key component in the valve. Its design, material and performance directly affect the use effect and safety performance of the valve. It is often used for opening and closing control and flow and temperature regulation of water users such as faucets or showers.

[0003] For example, a two-inlet and two-outlet valve core disclosed in Chinese patent No. CN201921359678.3 includes a valve body and a rocker mechanism, a moving porcelain piece and a fixed porcelain piece which are sequentially arranged in the valve body from top to bottom. The valve body includes a hollow shell and a base fitted at the bottom of the shell, the base is snap-connected with the shell, the base is provided with a mixed water outlet hole and a cold water inlet hole, a cold water outlet hole and a hot water inlet hole surrounding the mixed water outlet hole, the fixed porcelain piece is provided with a first cold water hole, a second cold water hole, a hot water hole and a mixed water hole which are respectively opposite to and connected with the cold water inlet hole, the cold water outlet hole, the hot water inlet hole and the mixed water outlet hole; the moving porcelain piece is arranged in a superimposed manner with the fixed porcelain piece, and a cold water groove for connecting the first cold water hole and the second cold water hole and a mixed water groove for connecting the first cold water hole, the hot water hole and the mixed water hole are provided on the bottom surface of the moving porcelain piece; the rocker mechanism is used to drive the moving porcelain piece to slide at the first position and the second position and to drive the moving porcelain piece to rotate. In addition to forming a mixed water circuit that usually discharges cold and hot water, the valve core can also form a single cold water circuit that only discharges cold water. Through the swing and rotation of the swing rod of the swing rod mechanism, the switching of the single cold water circuit and the mixed water circuit can be achieved, and the water outlet flow of the single cold water circuit and the water outlet temperature of the mixed water circuit can be controlled.

[0004] The mixed water outlet hole, cold water inlet hole, cold water outlet hole and hot water inlet hole of the above-mentioned valve core are distributed at intervals on the base. That is to say, the above-mentioned valve core is a bottom-in and bottom-out valve core. Both the water inlet pipe and the water outlet pipe need to be connected to these four channels. In order to ensure the circulation area of ​​cold water and hot water, the diameter of the base and the fixed ceramic plate is larger, which makes the overall volume of the valve core larger, which is not conducive to controlling production costs; moreover, during use, the fluctuating water pressure in the water supply pipe directly acts on the moving ceramic plate, which increases the spacing between the moving ceramic plate and the fixed ceramic plate, affecting the service life of the valve core; in addition, the above-mentioned valve core is not suitable for use in valves that require side water inlet. The spacing between the cold water and hot water pipes is small, and the installation convenience is poor. There is a need for further improvement of this type of valve core. Utility Model Content

[0040] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0041] A side water inlet valve core, such as Figures 1 to 10 As shown, including:

[0042] The housing 100 has an inner cavity 110 and a water inlet hole 120 and a water inlet hole 130 communicating with the inner cavity 110. The number of the water inlet hole 120 and the number of the water inlet hole 130 are at least one, and the water inlet hole 120 and the water inlet hole 130 are distributed on the side wall of the housing 100.

[0043] A fixed valve plate 200, the fixed valve plate 200 is circumferentially limited in the inner cavity 110, and a water outlet channel 210 is opened on the fixed valve plate 200;

[0044] The movable valve disc 300 is disposed in the inner cavity 110 and abuts against the fixed valve disc 200. There is a gap between the movable valve disc 300 and the inner cavity 110 for water to flow through. The movable valve disc 300 is provided with a switching hole 1 310 and a switching hole 2 320 at intervals. The switching hole 2 320 can be communicated with the water inlet hole 2 130, and the fixed valve disc 200 can cover the switching hole 1 310 or the switching hole 2 320;

[0045] A connecting member 400, the connecting member 400 is clamped with the movable valve plate 300, and a water inlet channel 410 is provided in the connecting member 400 to connect the water inlet hole 120 with the switching hole 1 310;

[0046] The valve stem 500, the inner end of the valve stem 500 is located in the inner cavity 110 and is connected to the connecting piece 400, and the outer end of the valve stem 500 passes through the outer shell 100. The valve stem 500 drives the connecting piece 400 and the movable valve plate 300 to rotate, thereby adjusting the connection area between the switching hole 1 310, the switching hole 2 320 and the water outlet channel 210, and then realizing the adjustment of the outlet water temperature.

[0047] like Figure 2-Figure 5 As shown, the inner diameter of the inner cavity 110 is H1, and the outer diameter of the inner cavity 110 is H2, H2 ≥ H1. In some embodiments, the cross section of the inner cavity 110 is trapezoidal, and the outer diameter of the inner cavity 110 is larger than the inner diameter of the inner cavity 110, so that the fixed valve disc 200, the movable valve disc 300, the connecting piece 400, and the valve stem 500 can be easily installed in the inner cavity 110; at the same time, the distance between the movable valve disc 300 and the inner cavity 110 can be increased, so that the second switching hole 320 and the second water inlet hole 130 are always connected.

[0048] like Figure 4 , Figure 6 As shown, a positioning groove 111 is provided on the side wall of the inner cavity 110 , and a positioning block 220 adapted to the positioning groove 111 is provided on the edge of the fixed valve plate 200 . After the positioning block 220 is inserted into the positioning groove 111 , the positioning groove 111 limits the circumferential position of the fixed valve plate 200 .

[0049] A base 600 is clipped or threadedly connected to the opening of the inner cavity 110, and the base 600 abuts against the fixed valve plate 200, so that the base 600 limits the fixed valve plate 200, the movable valve plate 300, the connecting piece 400, and the valve stem 500 as a whole axially in the inner cavity 110. The base 600 is also provided with a water outlet hole 610 connected to the water outlet channel 210; the base 600 and the fixed valve plate 200 are abutted against each other through a gasket 620 with elastic deformation properties.

[0050] An assembly groove 420 is provided at the upper end of the connecting member 400 , and a protrusion 510 adapted to the assembly groove 420 is provided at the inner end of the valve stem 500 . After the protrusion 510 is inserted into the assembly groove 420 , the assembly groove 420 limits the protrusion 510 in the circumferential direction.

[0051] A flange 520 is provided at the inner end of the valve stem 500, and a placement groove 112 is opened at the inner end of the inner cavity 110. The bottom of the placement groove 112 abuts against the flange 520 and limits the flange 520, so that the valve stem 500 cannot be separated from the placement groove 112; further, in order to reduce the wear between the flange 520 and the placement groove 112, the flange 520 and the placement groove 112 are abutted against each other through a gasket 521.

[0052] The side wall of the inner cavity 110 has a limiting groove 113, and the outer wall of the connecting member 400 is provided with a stopper 430, which is located in the limiting groove 113. The limiting groove 113 can limit the rotational stroke of the stopper 430, or in other words, the rotational stroke of the valve stem 500, the connecting member 400, and the movable valve plate 300 is constrained by the limiting groove 113. In some embodiments, the stopper 430 is provided on the valve stem 500, thereby omitting the stopper 430 provided on the connecting member 400. As another solution, a limiting block 1 and a limiting block 2 are provided at intervals on the side wall of the inner cavity 110, and a travel groove for the stopper 430 to rotate is formed between the limiting block 1 and the limiting block 2. The travel groove replaces the limiting groove 113, and can also limit the rotational stroke of the valve stem 500.

[0053] A mounting groove 530 is disposed outside the valve stem 500 , and a retaining spring 531 is disposed inside the mounting groove 530 . The retaining spring 531 abuts against the housing 100 and limits the axial position of the valve stem 500 .

[0054] like Figure 5 , Figure 6 As shown, the water inlet channel 410 includes a horizontal hole 411 and a vertical hole 412 that are connected to each other. The horizontal hole 411 is connected to the water inlet hole 120, and the vertical hole 412 is always connected to the switching hole 310. An annular groove 440 is provided on the outer wall of the connecting member 400. The annular groove 440 connects the water inlet hole 120 with the water inlet channel 410. The annular groove 440 increases the distance between the water inlet channel 410 and the inner cavity 110, so that the water flow rate from the water inlet hole 120 into the water outlet channel 210 is larger.

[0055] The outer wall of the connector 400 is provided with a sealing groove 1 450 and a sealing groove 2 460, a sealing ring 1 451 is provided in the sealing groove 1 450, and a sealing ring 2 461 is provided in the sealing groove 2 460. The sealing ring 1 451 and the sealing ring 2 461 can both be pressed against the inner cavity 110, so that the water inlet channel 410 and the switching hole 2 320 are in a cut-off state, and the water flows in the water inlet channel 410 and the switching hole 2 320 will not interfere before entering the water outlet channel 210. Correspondingly, the outer wall of the housing 100 is provided with a sealing groove 3 140 and a sealing groove 4 150, and a sealing ring 141 is provided in the sealing groove 3 140 and the sealing groove 4 150, and the outer ring of the sealing ring 141 is pressed against the inner wall of the valve, so that the water inlet hole 120 and the water inlet hole 2 130 are cut off.

[0056] The working principle of the utility model is as follows:

[0057] The valve core is installed in a valve or a faucet, so that the water inlet hole 120 and the water inlet hole 130 are connected to the water inlet waterway in the valve or the faucet, and the water outlet hole 610 is connected to the water outlet waterway. It is assumed that the water inlet hole 120 is connected to cold water and the water inlet hole 2 130 is connected to hot water.

[0058] The valve core is used as a water mixing valve: the user rotates the valve stem 500 to synchronously drive the connecting piece 400 and the movable valve plate 300 to rotate, thereby changing the positions of the switching hole 1 310 and the switching hole 2 320. Figure 8 As shown, when only the switching hole 1 310 is connected to the water outlet channel 210, the switching hole 2 320 is covered by the fixed valve plate 200, and the cold water flows out through the water inlet hole 120, the inner cavity 110, the annular groove 440, the water inlet channel 410, the switching hole 1 310, the water outlet channel 210, and the water outlet hole 610 in sequence; Fig.10 As shown, when the switching hole 1 310 and the switching hole 2 320 are both connected to the water outlet channel 210, cold water and hot water both enter the water outlet channel 210 and are mixed into warm water and flow out from the water outlet hole 610. As the valve stem 500 continues to rotate, the connection area between the switching hole 2 320 and the water outlet channel 210 gradually increases, and the connection area between the switching hole 1 310 and the water outlet channel 210 gradually decreases, that is, the temperature of the outlet water can be adjusted by changing the connection area between the switching hole 1 310, the switching hole 2 320 and the water outlet channel 210.

[0059] like Fig. 9 As shown, when only the second switching hole 320 is connected to the water outlet channel 210, the first switching hole 310 is covered by the fixed valve plate 200. At this time, only hot water flows out from the second water inlet hole 130, the inner cavity 110, the second switching hole 320, the water outlet channel 210, and the water outlet hole 610.

[0060] Assuming that the water inlet hole 120 is connected to tap water and the water inlet hole 2 130 is connected to purified water (drinking water), the valve core can also be used as a water diversion valve.

[0061] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
