Description

Technical Field

[0001] This application belongs to the field of valve core technology, and in particular relates to a novel valve core for use in valves. Background Technology

[0002] The filter of a water purifier is installed at the front end of the pipeline to filter and purify water. A multi-channel valve is an indispensable device on fluid transport pipelines. In civilian applications, it is usually installed at the water inlet of water-related equipment such as water-related household appliances. The valve core on the multi-channel valve achieves the function of switching water sources.

[0003] However, there are significant shortcomings in actual production, use, maintenance, and safety. For example, ball valves are expensive, inconvenient to assemble, and require high opening and closing torque. Improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a novel valve core for use in valves, which enables water flow to pass through the valve core and achieves on / off control of water flow.

[0005] This application provides a novel valve core for use in valves, comprising:

[0006] The valve core housing is provided with mounting holes, and the valve core housing is provided with a first flow port;

[0007] The valve core rod is movably installed in the mounting hole and is sealed to the valve core housing;

[0008] The circulation channel is used to connect to the first circulation port;

[0009] A closed structure, placed on the valve core rod, is used to block the first flow port;

[0010] When the flow channel corresponds to the first flow port of the valve core shell, water can flow through the first flow port; when the closed structure corresponds to the first flow port of the valve core shell, it blocks the water from flowing through the first flow port.

[0011] Furthermore, the circulation channel includes:

[0012] The flow channel is located on the valve core rod;

[0013] The second flow port is connected to the flow channel and can correspond to the first flow port.

[0014] Furthermore, the circulation channel also includes:

[0015] The guide surface is placed on the valve core rod and can correspond to the first flow port.

[0016] Furthermore, the closed structure includes:

[0017] A block is installed on the valve core rod. When the block aligns with the first flow port, it blocks the water flow through the first flow port.

[0018] Furthermore, the closed structure also includes:

[0019] The sealing element is installed obliquely on the valve stem, dividing the valve stem into a flow area and a closed area.

[0020] Furthermore, it also includes:

[0021] The filter screen, in a cylindrical shape, is fitted around the valve core housing and is used to filter and intercept impurities at the first flow port.

[0022] Furthermore, the valve core housing includes:

[0023] Water distribution grooves are located on the outer wall of the valve core housing and correspond to the filter screen.

[0024] Furthermore, the valve core housing also includes:

[0025] The second sealing ring is installed on the valve core housing and abuts against one side of the filter screen.

[0026] Furthermore, the valve core housing also includes:

[0027] The contact surface is placed on the outer wall of the valve core housing and abuts against the other side of the filter screen.

[0028] Furthermore, the valve core housing also includes:

[0029] The groove is placed on the valve core housing and corresponds to the end of the filter screen.

[0030] The beneficial effects of this application are:

[0031] 1. The valve core rod and valve core shell can move relative to each other. By controlling the first flow port and the second flow port to correspond or be staggered, the flow of water between the first flow port and the flow channel can be controlled.

[0032] 2. The closed structure can be used to block the first flow port, improve the sealing performance after blocking, and make it difficult for water to flow through the gap between the valve core rod and the valve core shell.

[0033] 3. The stability of the filter screen and water distribution tank installation structure is ensured, while also guaranteeing the smooth flow of water to the first flow outlet. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0044] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0045] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0046] Example 1:

[0047] like Figures 1-7 As shown, this application embodiment provides a novel valve core for use in valves, comprising:

[0048] The valve core housing is provided with mounting holes, and the valve core housing is provided with a first flow port;

[0049] The valve core rod is movably installed in the mounting hole and is sealed to the valve core housing;

[0050] The circulation channel is used to connect to the first circulation port;

[0051] A closed structure, placed on the valve core rod, is used to block the first flow port;

[0052] When the flow channel corresponds to the first flow port of the valve core shell, water can flow through the first flow port; when the closed structure corresponds to the first flow port of the valve core shell, it blocks the water from flowing through the first flow port.

[0053] The valve core rod is installed in the mounting hole, allowing it to mate with the valve core shell. After installation, a clearance exists between the valve core rod and the valve core shell. A first sealing ring, typically an O-ring, is embedded in either the valve core rod or the valve core shell. This first sealing ring ensures a seal between the valve core rod and the valve core shell, preventing water leakage through the gap. The valve core rod and valve core shell can rotate or extend along their axis. When the valve core rod and valve core shell move relative to each other, connecting one end of the first flow port to the flow channel, water can flow through this connection. The other end of the flow channel, located at the port of the mounting hole, leads to the outside of the valve core. When the valve core rod and valve core shell move relative to each other, connecting the first flow port to the closing structure, it blocks water flow through the first flow port. The flow channel and closing structure allow for control of water flow interruption.

[0054] Example 2:

[0055] like Figure 3 As shown, this application embodiment provides a novel valve core for use in valves. In addition to the above-mentioned technical features, the flow channel further includes:

[0056] The flow channel is located on the valve core rod;

[0057] The second flow port is connected to the flow channel and can correspond to the first flow port.

[0058] When the first flow port corresponds to the second flow port, one end of the flow channel corresponds to the first flow port through the second flow port, and the other end of the flow channel corresponds to the port of the flow channel and is located at the end of the valve core rod. Water can flow between the first flow port, the second flow port, and the flow channel. The second flow port is connected to the flow channel. The side structure of the second flow port includes cases where it is connected to or not connected to the end of the valve core rod.

[0059] Example 3:

[0060] like Figure 4 As shown, this application embodiment provides a novel valve core for use in valves. In addition to the above-mentioned technical features, the flow channel further includes:

[0061] The guide surface is placed on the valve core rod and can correspond to the first flow port.

[0062] The guide surface is set on the valve core rod. When the guide surface and the valve core shell form a flow channel, water can flow from the first flow port and the flow channel. This embodiment is a parallel embodiment to the previous embodiment, and the strength requirement of the valve core rod is higher than that of the previous embodiment.

[0063] Example 4:

[0064] like Figures 2-5 As shown, this application embodiment provides a novel valve core for use in valves. In addition to the above-mentioned technical features, the closing structure further includes:

[0065] A block is installed on the valve core rod. When the block aligns with the first flow port, it blocks the water flow through the first flow port.

[0066] Furthermore, a connecting part is provided in the middle of the first flow port.

[0067] The plug is fitted onto the valve core rod. When the plug aligns with the first flow port, it can block the first flow port and prevent water from flowing through it. The connecting part is placed in the first flow port and is integrally connected to the valve core shell. When the plug aligns with the first flow port, its own elasticity makes the middle part of the plug easily bulge outward, affecting the movement of the plug at the first flow port. The connecting part can abut against the plug, making the movement of the plug smoother and more stable.

[0068] Depending on the different movement patterns of the valve core rod and valve core shell, the position of the plug will also be different. When the valve core rod and valve core shell rotate, the plug and the first flow port are located on the same circumferential surface of the valve core rod. The figure shows the distribution of the plug and the first flow port around the axis of the valve core rod.

[0069] When the valve core rod and valve core shell move in a telescopic manner, the axis of the distribution of the plug and the first flow port is parallel to the axis of the valve core shell. This scheme is a parallel scheme to the previous scheme, which only adjusts the position of the plug and is not shown in the figure.

[0070] Example 5:

[0071] like Figure 6 , Figure 7 As shown, this application embodiment provides a novel valve core for use in valves. In addition to the above-mentioned technical features, the closing structure further includes:

[0072] A seal is installed on the valve stem to divide the valve stem into a flow area and a closed area.

[0073] The sealing element uses an O-ring, which is embedded in the valve core rod, dividing the valve core rod into a flow area and a closed area. The closed area is formed by the sealing element and the first sealing ring. The second flow port is placed in the flow area. When the first flow port corresponds to the second flow port in the flow area, water can flow through the second flow port in the flow area. When the first flow port corresponds to the closed area, the water flow is blocked by the closed area. This embodiment is a parallel embodiment to the previous embodiment. The sealing element is installed around the valve core rod along the axial direction of the valve core rod. Compared with the previous embodiment, it can improve the coaxiality of the valve core rod and the valve core shell, and further improve the stability of the valve core rod and the valve core shell during movement.

[0074] When the valve core rod rotates, the plane of the groove on the valve core rod where the seal is installed has a certain angle with the axis of the valve core rod. The seal is an O-ring that can be installed on the valve core rod by deformation. As shown in the figure, when the valve core rod rotates, it can switch between the flow area and the closed area.

[0075] When the valve core rod is telescopic, the plane of the groove on the valve core rod where the seal is installed is perpendicular to the axis of the valve core rod, and the flow area and the closed area are distributed axially. This scheme is a parallel scheme to the previous scheme, and is not shown in the figure.

[0076] Example 6:

[0077] like Figures 1-3 As shown, this application embodiment provides a novel valve core for use in valves, which, in addition to the above-mentioned technical features, further includes:

[0078] The filter screen, in a cylindrical shape, is fitted around the valve core housing and is used to filter and intercept impurities at the first flow port.

[0079] Furthermore, the valve core housing includes:

[0080] Water distribution grooves are located on the outer wall of the valve core housing and correspond to the filter screen.

[0081] The filter screen is fitted onto the outer wall of the valve core housing. The filter screen can filter and intercept impurities in the water in the first flow port. Its filtration performance is mainly determined by the mesh size of the filter screen used. The water distribution groove is distributed on the outer wall of the valve core housing. When the filter screen is installed, it is easy to abut against the outer wall of the valve core housing. The water distribution groove can improve the flow of water between the valve core housing and the filter screen, and at the same time improve the support of the outer wall of the valve core housing to the filter screen. This can eliminate the need for the installation of the filter screen bracket and reduce the production cost of the filter screen.

[0082] The connection between the filter screen and the valve core shell can be integrated through bonding, welding, or non-integrated connection where both ends are in contact with other components, snap-fitted, clamped, or tightened.

[0083] Example 7:

[0084] like Figure 3 , Figure 8 As shown, this application embodiment provides a novel valve core for use in valves. In addition to the above-mentioned technical features, the valve core shell further includes:

[0085] The second sealing ring is installed on the valve core housing and abuts against one side of the filter screen.

[0086] Furthermore, the valve core housing also includes:

[0087] The contact surface is placed on the outer wall of the valve core housing and abuts against the other side of the filter screen.

[0088] The second sealing ring is an O-ring, primarily used to enhance the sealing performance between the valve core housing and other mating parts such as the valve body. After the filter screen is installed onto the valve core housing, the second sealing ring abuts against one end of the filter screen, achieving a seal at that end. The other end of the filter screen abuts against a contact surface, which can be a flat or conical surface. Figure 7 Figure a shows a schematic diagram of the filter screen abutting against the conical surface, and figure b shows a schematic diagram of the filter screen abutting against the flat surface. When the filter screen abuts against the contact surface, it can ensure the sealing performance of the other end of the filter screen and ensure the filtration effect of the filter screen.

[0089] Example 8:

[0090] like Figure 3 As shown, this application embodiment provides a novel valve core for use in valves. In addition to the above-mentioned technical features, the valve core shell further includes:

[0091] The groove is placed on the valve core housing and corresponds to the end of the filter screen.

[0092] An O-ring can be installed in the groove. When installing the filter screen, the O-ring is embedded in the groove and placed inside the filter screen. This embodiment is a parallel solution to the previous embodiment.
