[0001] The utility model relates to the technical field of valve parts, in particular to an angle valve. Background Art

[0002] An angle valve, also known as an angle stop valve, a ball valve, an angle valve or a corner stop valve, is a common water pipe connection component widely used in household pipe systems to control the flow of water by opening and closing the angle valve. The valve body of the angle valve has a water inlet, a water volume control port and a water outlet. When in use, the water inlet is connected to the water inlet pipe, a valve core for controlling the opening and closing of the water outlet is arranged in the water volume control port, and a faucet is installed at the water outlet. When the water pressure is too high or the faucet leaks, the water source can be quickly cut off by closing the angle valve, avoiding the trouble of closing the main valve in the house. However, the existing angle valves usually have the following problems: 1) The valve cores of most existing angle valves are ceramic pieces or ball valve type structures, resulting in a small flow channel in the angle valve, and it is easy to cause the phenomenon that the fluid cannot pass through in time; 2) Impurities in the water inlet pipe are easily carried by the fluid through the angle valve into the terminal water using device, causing blockage and thus affecting the normal use of users.

[0050] Embodiment 1

[0051] Figure 1 Shows a schematic structural view of the angle valve provided in this embodiment. Figure 2 Shows a schematic cross-sectional structural view of the angle valve provided in this embodiment from one perspective. Figure 3 Shows a schematic cross-sectional structural view of the angle valve provided in this embodiment from another perspective. As Figures 1-3 shown, this embodiment provides an angle valve, which includes a valve body 100, a valve core 200 and a filter element 300. Among them, the valve body 100 has a water inlet flow channel 111 and a water outlet flow channel 112, and a sealing surface 113 is further provided in the valve body 100. The sealing surface 113 is located between the water inlet flow channel 111 and the water outlet flow channel 112; the valve core 200 is disposed in the valve body 100 with adjustable position and can fit or move away from the sealing surface 113 to cut off or connect the passage between the water inlet flow channel 111 and the water outlet flow channel 112; the filter element 300 is disposed in the valve body 100.

[0052] The angle valve provided in this embodiment is applied to a household pipeline system. The inlet of the water inlet flow channel 111 can be connected to a water inlet pipeline, and the outlet of the water outlet flow channel 112 can be connected to a faucet. By adjusting the valve core 200, it can be made to fit or move away from the sealing surface 113 of the valve body 100 to selectively open or close the passage between the water inlet flow channel 111 and the water outlet flow channel 112, thereby realizing the connection or cut-off of the fluid between the water inlet pipeline and the faucet. By providing a sealing surface 113 in the valve body 100 to cooperate with the valve core 200 to realize the cut-off and connection of the passage between the water inlet flow channel 111 and the water outlet flow channel 112, a cut-off type sealing structure is formed between the valve body 100 and the valve core 200. Compared with the ball valve type sealing structure or the ceramic sheet type sealing structure in the prior art, this setting can form a larger connecting diameter on an angle valve with the same size, thereby increasing the fluid flow rate through the angle valve to enable the fluid to pass quickly. By providing a filter element 300 in the valve body 100, impurities in the water inlet pipeline can be filtered to prevent them from flowing into the terminal water using device with the fluid and causing blockage, thereby ensuring the normal water use of users.

[0053] Figure 4 The structural schematic diagram of the valve core 200 provided in this embodiment is shown. As Figure 4 and in combination with Figure 2 shown, the valve core 200 includes a valve stem 210 and a first sealing portion 220 connected to the valve stem 210. The valve stem 210 is movably connected to the valve body 100. Adjusting the valve stem 210 can drive the first sealing portion 220 to fit or move away from the sealing surface 113. When it is necessary to connect the passage between the water inlet flow channel 111 and the water outlet flow channel 112, the valve stem 210 can be adjusted to make the first sealing portion 220 move away from the sealing surface 113. At this time, the first sealing portion 220 is spaced from the sealing surface 113, and the fluid in the water inlet flow channel 111 can flow to the water outlet flow channel 112 from the gap between the first sealing portion 220 and the sealing surface 113. When it is necessary to cut off the passage between the water inlet flow channel 111 and the water outlet flow channel 112, the valve stem 210 can be adjusted to make the first sealing portion 220 fit with the sealing surface 113. At this time, the fluid in the water inlet flow channel 111 cannot flow to the water outlet flow channel 112.

[0054] In this embodiment, the valve stem 210 is threadedly connected to the valve body 100. By rotating the valve stem 210, the first sealing portion 220 can be driven to rise and fall along the axial direction of the valve stem 210 to approach or move away from the sealing surface 113, thereby realizing the opening and closing of the passage between the water inlet channel 111 and the water outlet channel 112. The structure is simple and easy to adjust. Of course, this embodiment does not limit the connection method between the valve stem 210 and the valve body 100, as long as the valve stem 210 can move relative to the valve body 100, so as to adjust the position of the first sealing portion 220 relative to the sealing surface 113. In addition, this embodiment does not limit the sealing method between the valve body 100 and the valve core 200, and the designer can adjust the specific structure of the valve core 200 according to actual needs.

[0055] To facilitate the processing of the valve core 200, in the present embodiment, the valve stem 210 and the first sealing portion 220 are an integrated structure, and the assembly process therebetween is omitted, thereby improving the processing efficiency and the assembly efficiency.

[0056] Optionally, a first sealing member 401 is provided on the first sealing portion 220. When the first sealing portion 220 is attached to the sealing surface 113, the first sealing member 401 is pressed against the sealing surface 113, thereby ensuring a reliable seal between the two. Optionally, a first receiving groove 221 for receiving the first sealing member 401 is provided on the first sealing portion 220, so as to achieve a stable installation of the first sealing member 401 and prevent it from falling off during use. Of course, in other embodiments, the first receiving groove 221 can also be provided on the sealing surface 113, and the first sealing member 401 can be installed in the first receiving groove 221 on the sealing surface 113, which can also achieve the above-mentioned effect. Among them, the first sealing member 401 can adopt a rubber sealing ring, which has a good sealing effect and a low processing cost.

[0057] like Figures 2-4 As shown, a screw groove 212 is provided at one end of the valve stem 210 away from the first sealing portion 220 (i.e., the top of the valve stem 210), and a avoidance hole 1001 corresponding to the screw groove 212 on the valve stem 210 is provided on the valve body 100. When the valve core 200 needs to be switched between the position of being in contact with or away from the sealing surface 113, the operator can use a screwing tool compatible with the screw groove 212 to directly rotate the valve stem 210 through the avoidance hole 1001, which is more convenient. Optionally, the screw groove 212 can be a straight groove or a cross groove.

[0058] To prevent the fluid in the water outlet channel 112 from flowing out through the avoidance hole 1001, a second seal 402 is provided between the valve stem 210 and the valve body 100. Optionally, a second receiving groove 211 for receiving the second seal 402 is provided on the valve stem 210 to achieve stable installation of the second seal 402 and prevent it from falling off during use. Of course, in other embodiments, the second receiving groove 211 can also be provided on the valve body 100, and the second seal 402 can be installed in the second receiving groove 211 of the valve body 100, which can also achieve the above effects. Among them, the second seal 402 can be a rubber sealing ring, which has good sealing effect and low processing cost.

[0059] Continue as Figures 2-4 As shown, the valve body 100 includes a valve main body 110 and a valve cover 120. The water inlet channel 111, the water outlet channel 112, and the sealing surface 113 are all provided in the valve main body 110, and the valve cover 120 is installed on the valve main body 110. Specifically, an installation port 114 is further provided at the top of the valve main body 110, and a part of the valve cover 120 is installed in the installation port 114. Optionally, an external thread is provided on the outer wall of the valve cover 120, and an internal thread is provided on the inner wall of the installation port 114. The valve cover 120 is threadedly connected to the valve main body 110, and the threaded connection has the advantages of firm connection and convenient disassembly and assembly. Of course, the connection method between the valve cover 120 and the valve main body 110 in this embodiment is not limited, as long as the sealing connection between the valve cover 120 and the valve main body 110 can be achieved.

[0060] In this embodiment, the axis direction of the water inlet channel 111 is arranged parallel to the axis direction of the installation port 114, and the axis direction of the water outlet channel 112 is arranged at an angle to the axis direction of the water inlet channel 111. Further, the water inlet channel 111 is coaxially arranged with the installation port 114 for easy processing.

[0061] In this embodiment, the valve cover 120 is a cylindrical structure, and its upper opening forms the above-mentioned avoidance hole 1001, and its lower opening is communicated with the water outlet channel 112.

[0062] Specifically, the valve stem 210 includes a rod portion 2101, a limiting portion 2102 and a second sealing portion 2103 that are both provided on the rod portion 2101. The limiting portion 2102 is adjustably connected to the valve body 100, and the second sealing portion 2103 is hermetically connected to the inside of the valve body 100. Specifically, the second seal 402 is provided on the second sealing portion 2103. By providing the limiting portion 2102 and the second sealing portion 2103, the sealing connection between the valve stem 210 and the valve body 100 is achieved. Among them, the second receiving groove 211 is provided on the second sealing portion 2103.

[0063] Optionally, a third seal 403 is further provided between the valve cover 120 and the valve body 110 to prevent the fluid in the water inlet flow channel 111 from flowing out through the gap between the valve body 110 and the valve cover 120. Among them, the third seal 403 can be a rubber sealing ring, which has good sealing effect and low processing cost.

[0064] Continue as Figure 3 shown, the filter element 300 is located in the water inlet flow channel 111. With this setting method, not only can the impurities in the water inlet pipeline be filtered to prevent them from flowing into the terminal water-using device with the fluid, but also the accumulation of impurities in the valve body 100 can be avoided, which may cause the angle valve to be blocked, thereby ensuring the service performance of the angle valve; in addition, after long-term use, the valve body 100 can be removed from the water inlet pipeline, and the filter element 300 located in the water inlet flow channel 111 can be flushed to remove the impurities on it, so as to avoid excessive impurities on the filter element 300 affecting the filtering effect.

[0065] Optionally, the filter element 300 is detachably connected to the valve body 100. Specifically, the filter element 300 is detachably connected to the valve body 110. After long-term use or when the filter element 300 is damaged, the filter element 300 can be removed from the valve body 100, and then a new filter element 300 can be replaced, which is convenient and fast to operate. In this embodiment, the filter element 300 is installed in the valve body 110 by an interference fit method, which has a simple structure and is convenient for disassembly and assembly. Of course, in other embodiments, the filter element 300 can also be installed in the valve body 110 by a snap connection or a snap ring limit method, which can also achieve the above effects.

[0066] It should be noted that the specific structure of the filter element 300 in this embodiment is not limited, and it can be a metal filter screen or an injection filter screen in the prior art.

[0067] Embodiment 2

[0068] This embodiment provides an angle valve, and the specific structure of this angle valve is substantially the same as that of the angle valve in Embodiment 1, except that the connection method between the valve cover 120 and the valve body 110 is different.

[0069] Figure 5 shows the structural schematic diagram of the angle valve provided in this embodiment. Figure 6 shows the cross-sectional structural schematic diagram of the angle valve provided in this embodiment from one perspective. Figure 7 shows the cross-sectional structural schematic diagram of the angle valve provided in this embodiment from another perspective. As Figures 5-7As shown, in this embodiment, the valve cover 120 is hermetically sleeved outside the valve body 110. An avoidance hole 1001 is provided at the top of the valve cover 120 to facilitate the operator to screw the valve stem 210. Optionally, an internal thread is provided on the inner wall of the valve cover 120, and an external thread is provided on the outer wall of the valve body 110 to achieve a firm connection between the valve body 110 and the valve cover 120.

[0070] Optionally, an installation port 114 is further provided at the top of the valve body 110, so that when assembling the angle valve, the valve core 200 can be inserted into the valve body 110 from the installation port 114.

[0071] Refer to Figure 1 and Figure 2 , in the first embodiment, since the upper opening of the valve cover 120 (i.e., the avoidance hole 1001) is adapted to the outer diameter of the limiting portion 2102, it is easy for the operator to screw out the valve stem 210 from the valve body 100 when screwing the valve stem 210. To solve this problem, as Figure 5 and Figure 6 shown, in this embodiment, the inner diameter of the avoidance hole 1001 is smaller than the outer diameter of the limiting portion 2102, and the inner diameter of the avoidance hole 1001 is greater than or equal to the outer diameter of the rod portion 2101, so as to prevent the valve stem 210 from being screwed out from the valve body 100 when rotating, and at the same time ensure that the screwing tool can smoothly extend into the avoidance hole 1001 to screw the valve stem 210.

[0072] It should be noted that the specific structure of the valve core 200 in this embodiment is the same as the specific structure of the valve core 200 in the first embodiment. The limiting portion 2102 of the valve stem 210 is threadedly connected to the inner wall of the valve body 110. A second sealing member 402 is provided between the second sealing portion 2103 of the valve stem 210 and the valve body 110, so as to achieve a sealed connection between the valve stem 210 and the valve body 100, and prevent the fluid in the water outlet channel 112 from flowing out from the avoidance hole 1001.

[0073] Embodiment Three

[0074] This embodiment provides an angle valve. The specific structure of this angle valve is substantially the same as the specific structures of the angle valves in the first embodiment and the second embodiment, except that: the structure of the valve body 100 is different.

[0075] Figure 8 shows a schematic structural diagram of the angle valve provided in this embodiment. Figure 9 shows a cross-sectional structural diagram of the angle valve provided in this embodiment from one perspective. Figure 10 shows a cross-sectional structural diagram of the angle valve provided in this embodiment from another perspective. As Figures 8-10As shown, the valve body 100 of this embodiment does not have a valve cover. Specifically, an installation opening 114 is provided at the top of the valve body 100. When assembling the angle valve, the valve core 200 can be inserted into the valve body 100 from the installation opening 114. This embodiment can omit the setting of the valve cover to simplify the assembly process of the angle valve, thereby improving the assembly efficiency of the angle valve and reducing the processing cost.

[0076] It should be noted that the specific structure of the valve core 200 in this embodiment is the same as that of the valve core 200 in the first embodiment. The limiting portion 2102 of the valve stem 210 is threadedly connected to the inner wall of the valve body 100, and a second sealing member 402 is provided between the second sealing portion 2103 of the valve stem 210 and the valve body 100, so as to achieve a sealed connection between the valve stem 210 and the valve body 100 and prevent the fluid in the water outlet channel 112 from flowing out from the installation opening 114.

[0077] To prevent the operator from screwing out the valve stem 210 from the valve body 100 when screwing the valve stem 210, in this embodiment, the installation opening 114 is a reduced opening that narrows inward to form an avoidance hole 1001. The inner diameter of the reduced opening is smaller than the outer diameter of the limiting portion 2102 and larger than the outer diameter of the rod portion 2101, so as to prevent the valve stem 210 from being screwed out from the valve body 100 when rotating, and at the same time ensure that the screwing tool can extend into the avoidance hole 1001 to screw the valve stem 210.

[0078] It should be particularly noted that in this embodiment, when assembling the angle valve, the valve core 200 needs to be inserted into the valve body 100 from the installation opening 114 first, and then the upper opening of the installation opening 114 is subjected to a necking process.

[0079] Embodiment Four

[0080] This embodiment provides an angle valve. The specific structure of this angle valve is substantially the same as that of the angle valve in the first embodiment, except that the installation position of the filter element 300 and the connection method between the valve core 200 and the valve body 100 are different.

[0081] Figure 11 Shows a schematic structural diagram of the angle valve provided in this embodiment. Figure 12 Shows a sectional structural diagram of the angle valve provided in this embodiment from one perspective. Figure 13 Shows a sectional structural diagram of the angle valve provided in this embodiment from another perspective. As Figures 11-13As shown, in this embodiment, the valve body 100 includes a valve main body 110 and a valve cover 120. The water inlet flow channel 111, the water outlet flow channel 112, and the sealing surface 113 are all arranged inside the valve main body 110. There is also an installation opening 114 provided at the top of the valve main body 110, and a part of the valve cover 120 is installed inside the installation opening 114. In this embodiment, the inner wall of the installation opening 114 of the valve main body 110 is provided with an internal thread, and the outer wall of the valve cover 120 is provided with an external thread, thereby realizing the fastening connection between the valve main body 110 and the valve cover 120.

[0082] In this embodiment, a through hole is opened on the valve cover 120, and the valve stem 210 is threadedly connected to the through hole of the valve cover 120, and this through hole forms the above-mentioned avoidance hole 1001.

[0083] Specifically, the valve stem 210 includes a rod portion 2101, a limiting portion 2102 and a second sealing portion 2103 both arranged on the rod portion 2101. The limiting portion 2102 is adjustably connected to the valve body 100, and the second sealing portion 2103 is hermetically connected to the inside of the valve body 100, that is, the second sealing member 402 is arranged on the second sealing portion 2103. Among them, the aperture of the through hole on the valve cover 120 is smaller than the outer diameter of the second sealing portion 2103, so as to prevent the operator from screwing out the valve stem 210 from the valve body 100 when screwing the valve stem 210.

[0084] Figure 14 The structural schematic diagram of the valve core 200 and the valve cover 120 provided in this embodiment is shown. As Figure 14 And in combination with Figure 13 As shown, one end of the valve core 200 close to the water inlet flow channel 111 is provided with a bearing portion 230, and the bearing portion 230 is used to bear the filter element 300. When it is necessary to clean the impurities on the filter element 300 or replace the filter element 300, the valve cover 120 together with the valve core 200 can be removed from the top of the valve main body 110. At this time, the filter element 300 can be taken out of the valve main body 110 together with the bearing portion 230, so as to realize the cleaning or replacement of the filter element 300, and the operation is convenient and fast.

[0085] Optionally, the bearing portion 230 is of a cylindrical structure, and a water passing channel 231 is opened on its side wall, and the filter element 300 is installed in the inner cylinder of the bearing portion 230. The setting of the water passing channel 231 can prevent the bearing portion 230 from obstructing the fluid flowing from the water inlet flow channel 111 to the water outlet flow channel 112, thereby ensuring the smoothness of the fluid passing through the angle valve.

[0086] In this embodiment, the filter element 300 is installed on the bearing portion 230 by an interference fit method, with a simple structure and convenient disassembly and assembly. Of course, in other embodiments, the filter element 300 can also be installed on the bearing portion 230 by a clamping or snap ring limiting method, and the above effects can also be achieved.
