Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, to a handle quick-connect angle ball valve and a pipeline valve. Background Technology

[0002] Ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of media. By rotating the ball 90 degrees, the fluid can be quickly and completely cut off or connected. Ball valves achieve sealing by using the clamping force of the valve body and bonnet to cause elastic-plastic deformation of the valve seat material. They are valves with a relatively heavy operating feel. To reduce the operating feel of ball valves, the handle is usually designed to be relatively long. This requires more installation space and is especially unsuitable for integrated installation environments such as water distribution tanks.

[0003] To address the issue of excessively long ball valve handles restricting operation, retractable handle ball valves have emerged on the market. For example, authorization announcement number CN212509749U discloses a ball valve with a retractable handle. This design reduces the tactile feedback by pulling and rotating an extension rod, which is then retracted after use. However, this pull-out method, which relies on rotating a limit block, does not involve rotating and fixing the extension rod, leading to potential misalignment during use. Furthermore, the handle remains quite long, making it unsuitable for operation in confined spaces.

[0004] Authorization notice number CN209469822U discloses a fluoropolymer-lined ball valve with a foldable handle. Rotating along a pin in the middle of the handle folds it, reducing its length to nearly half of its normal length. This reduces the protrusion and makes it less likely to be accidentally bumped, preventing changes in valve size due to contact. The handle can be folded back to extend its length during use. However, this pin-connected folding method subjects the pin to significant force, making it prone to failure and inconvenient for opening and closing the valve. Furthermore, the foldable handle restricts operation in confined spaces.

[0005] Authorization announcement number CN220302904U discloses a ball valve with a telescopic handle. The handle height is adjusted by the relative position of the telescopic bracket, the strip port and the sliding sleeve, but the length of the handle equivalent to the rotation axis of the valve ball cannot be changed. Moreover, the adjustment is made by threaded connection, resulting in low operating efficiency.

[0006] In view of this, this utility model is proposed. Utility Model Content

Under the action of the spring, the limiting adjustment groove is located above the limiting member to accommodate the limiting member or to deviate from the limiting member to disengage from the limiting member. The socket end is provided with a locking groove for cooperating and fixing with the limiting member. When the limiting adjustment groove accommodates the limiting member, the socket end is inserted into the socket or separated from the socket. When the limiting member is disengaged from the limiting adjustment groove, the socket end is inserted into the socket and fixed by the limiting member.

[0009] In an optional embodiment, the pressing member includes a square post, a side plate, and a boss. The square post is connected to the side plate to form an L-shape.

Connection and disassembly can be quickly made between the base and extension, or between any two adjacent extensions, offering convenience and efficiency. Pressing the pressing part compresses a spring, changing the position of the upper limit adjustment groove. When the upper limit adjustment groove aligns with the position of the limiting member, it provides space for the limiting member's movement, facilitating the release of the restriction and allowing the socket end to easily insert into or remove from the socket. After the socket end is inserted into the socket slot, the pressure on the pressing element is released. The spring's restoring force disengages the limiting adjustment groove on the pressing element from the limiting element. At this point, the surface of the pressing element can limit the limiting element, causing it to engage in the locking groove, thus securing the socket end and the socket slot. The adjustment of the handle assembly requires no tools. The length of the handle assembly can be adjusted at any time during the ball valve's opening and closing operation to adapt to operating space requirements. The handle assembly has a simple structure and is easy to manufacture. Attached Figure Description

[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0028] Example Please see Figure 1 and Figure 2 This embodiment provides a handle quick-connect angle ball valve 100, including a ball valve body 110 and a handle assembly 120. The handle assembly 120 is used to drive the valve stem 113 of the ball valve body 110 to rotate, thereby realizing the opening and closing of the ball valve body 110.

[0029] In this embodiment, the handle assembly 120 includes a base portion 121 and extension portions 122 for adjusting the length of the handle assembly 120. The number of extension portions 122 is 0-5. The base portion 121 is connected to the ball valve body 110 to control the opening and closing of the ball valve body 110. When the number of extension portions 122 is 0, it indicates that the handle assembly 120 can consist only of the base portion 121, which allows for the installation and adjustment of the ball valve body 110 in a small space. When the number of extension portions 122 is one or more, it indicates that the handle assembly 120 consists of the base portion 121 and the extension portions 122. The number of extension portions 122 can be adaptively increased or decreased according to the needs of the installation space.

[0030] Please see Figure 3 , Figure 4 and Figure 8To enable rapid installation and disassembly between the base portion 121 and the extended portion 122, or between two adjacent extended portions 122, in this embodiment, the base portion 121 is provided with a first socket pressing portion 123. One end of the extended portion 122 is provided with a socket end 124 for engaging with the first socket pressing portion 123 and a second socket pressing portion 125 for engaging with the socket end 124 of another adjacent extended portion 122. The first socket pressing portion 123 and the second socket pressing portion 125 have identical structures. By making the first socket pressing portion 123 and the second socket pressing portion 125 have identical structures, the structures of multiple extended portions 122 can be kept consistent, and all can be adapted to the base portion 121, saving costs.

[0031] The following details only the specific structure of the first socket pressing part 123 and the socket end 124 and their mutual cooperation. For the specific structure and cooperation of the socket end 124 of the other extended part 122 of the second pressing part, please refer to the above-described specific structure of the first socket pressing part 123 and the socket end 124 and their mutual cooperation.

[0032] Please see Figure 5 and Figure 6 The first socket pressing part 123 includes a socket body 126, a limiting member 127, a pressing member 128, and a spring 129. The socket body 126 has a square structure. The pressing body has a socket slot 1261, a through hole 1262 for accommodating the limiting member 127, and a pressing blind hole 1263. The socket slot 1261 is aligned with the axis of the pressing body. The opening direction of the socket slot 1261 is located on one side of the pressing body. The through hole 1262 is located on the upper surface of the pressing body and extends downward to the pressing groove. The through hole 1262 is located above the socket slot 1261 and communicates with the socket slot 1261. The pressing blind hole 1263 is located on the other side of the socket body 126, and the axis of the pressing blind hole 1263 is perpendicular to the axis of the through hole 1262. The pressing blind hole 1263 passes through the through hole 1262. The axes of any two of the socket 1261, through hole 1262 and press blind hole 1263 are perpendicular.

[0033] In this embodiment, the spring 129 is disposed within the pressing blind hole 1263, and the pressing member 128 is inserted into the pressing blind hole 1263 and abuts against the spring 129. The pressing member 128 is provided with a limit adjustment groove 1281. The pressing member 128 is located above the limiting member 127 and the position of the limit adjustment groove 1281 is adjusted by pressing. Under the action of the spring 129, the limit adjustment groove 1281 is located above the limiting member 127 to accommodate the limiting member 127 or... The offset limiting member 127 is used to disengage from the limiting member 127; the socket end 124 is provided with a locking groove 1241 for cooperating and fixing with the limiting member 127. When the limiting adjustment groove 1281 accommodates the limiting member 127, the socket end 124 is inserted into the socket 1261 or separated from the socket 1261; when the limiting adjustment groove 1281 disengages from the limiting member 127, the socket end 124 is inserted into the socket 1261 and fixed by the limiting member 127.

[0034] In this embodiment, by pressing the pressing member 128, the pressing member 128 compresses the spring 129, thereby changing the position of the upper limit adjustment groove 1281 of the pressing member 128. When the position of the upper limit adjustment groove 1281 is directly opposite the position of the limiting member 127, the upper limit adjustment groove 1281 provides a certain space for the movement of the limiting member 127, which facilitates the release of the restriction on the limiting member 127 and facilitates the insertion of the socket end 124 into or out of the socket 1261. After the socket end 124 is inserted into the socket 1261, the pressing of the pressing member 128 is released. At this time, the restoring force of the spring 129 causes the upper limit adjustment groove 1281 on the pressing member 128 to disengage from the limiting member 127. At this time, the surface of the pressing member 128 can limit the limiting member 127, so that the limiting member 127 is locked in the locking groove 1241, thereby fixing the socket end 124 and the socket 1261.

[0035] For further details, please refer to Figure 7 In this embodiment, the pressing member 128 includes a square post 1282, a side plate 1283, and a boss 1284. The square post 1282 and the side plate 1283 are connected to form an L-shape. The boss 1284 is connected to one end of the square post 1282. The square post 1282 and the side plate 1283 are inserted into the pressing blind hole 1263. The boss 1284 is located outside the pressing blind hole 1263. A spring 129 is connected to the square post 1282. A limiting adjustment groove 1281 is provided on the side plate 1283. The square post 1282 is provided with a spring blind hole 1285. The spring 129 is installed in the spring blind hole 1285 and one end of the spring 129 extending out of the spring blind hole 1285 is connected to the inner wall of the pressing blind hole 1263.

[0036] In this embodiment, by defining the specific structure of the pressing member 128 and setting the square column 1282 and the side plate 1283, the compression of the spring 129 by the pressing member 128 and the adjustment of the fiber adjustment groove are not interfered with each other. Furthermore, by setting the spring blind hole 1285, the spring 129 can only extend and retract within the spring blind hole 1285, without any positional deviation, resulting in smoother pressing. At the same time, the setting of the boss 1284 also facilitates precise pressing of the pressing point.

[0037] Furthermore, in this embodiment, the first socket pressing part 123 is also provided with a stop 1264 for restricting the pressing member 128 from dislodging. The length of the side plate 1283 is less than the length of the square column 1282, and a sliding area is formed between the side plate 1283 and the boss 1284. The stop 1264 is fixedly connected to the socket body 126 and located within the sliding area. The stop 1264 can limit the pressing member 128, preventing it from dislodging from the pressing blind hole 1263, thus ensuring the stability of the overall structure.

[0038] Furthermore, in this embodiment, the end of the through hole 1262 near the socket 1261 is set as a tapered hole 1265, the diameter of the tapered hole 1265 is smaller than the diameter of the limiting member 127; the setting of the tapered hole 1265 can ensure that the limiting member 127 in the through hole 1262 will not fall out of the tapered hole 1265, and only a part of the limiting member 127 extends out of the tapered hole 1265, thereby locking the socket body 126 and the socket end 124.

[0039] In this embodiment, both the socket 1261 and the insertion end 124 are square. The square structure means that the insertion end 124 can only move in the pulling direction. After the pulling direction is restricted, the various parts of the handle assembly 120 can be fastened together.

[0040] This embodiment does not limit the specific structure of the ball valve body 110. Any structure that meets the requirements of a conventional ball valve can be used as the ball valve body 110 in this embodiment. Specifically, this embodiment provides a typical but non-limiting example: the ball valve body 110 includes a valve body 111, a ball 112, a valve stem 113, and a valve cover 114. An L-shaped flow channel is provided inside the valve body 111, with its two ends connected to the valve body inlet 115 and the valve body outlet 116, respectively. The ball 112 is rotatably disposed inside the valve body 111 and has a flow channel for connecting the valve body inlet 115 and the valve body outlet 116. One end of the valve stem 113 is connected to the ball 112 to control the rotation of the ball 112, and the other end of the valve stem 113 is connected to the base portion 121. The base portion 121 has a mounting hole, and the valve stem 113 is inserted into the mounting hole and fixed by a nut 117. The valve cover 114 is installed on the upper end of the valve body 111 to close the valve body 111. The handle quick-connect angle ball valve 100 also includes a connecting pipe assembly 118 and a core assembly 119. The connecting pipe assembly 118 is connected to the valve body inlet 115, and the core assembly 119 is connected to the valve body outlet 116.

[0041] In addition, this embodiment also provides a pipeline valve, including a quick-connect angle ball valve 100 with an upper handle.

[0042] In summary, the handle-operated quick-connect angle ball valve 100 provided by this utility model defines the handle assembly 120, which consists of a base portion 121 and an extension portion 122. The length of the handle assembly 120 can be quickly adjusted by selecting the number of extension portions 122, adapting to operation in different spaces. The handle can be lengthened for effortless operation, or shortened for operation in confined spaces. Furthermore, the base portion 121 and the extension portions 122 are plugged together and fixed by a limiting member 127. The base portion 121 and the extension portions 122, or any two adjacent extension portions 122, can be quickly connected and disassembled, making it convenient and efficient. In this design, pressing the pressing part 128 compresses the spring 129, thereby changing the position of the upper limit adjustment groove 1281 on the pressing part 128. When the position of the upper limit adjustment groove 1281 is directly opposite the position of the limiting member 127, the upper limit adjustment groove 1281 provides a certain space for the movement of the limiting member 127, facilitating the release of the restriction on the limiting member 127 and making it easier for the socket end 124 to be inserted into or removed from the socket 1261. After the socket end 124 is inserted into the socket 1261, the pressing of the pressing part 128 is released. At this time, the restoring force of the spring 129 causes the upper limit adjustment groove 1281 on the pressing part 128 to disengage from the limiting member 127. At this time, the surface of the pressing part 128 can limit the limiting member 127, causing the limiting member 127 to be locked in the locking groove 1241, thereby fixing the socket end 124 and the socket 1261. The adjustment of the handle assembly 120 requires no tools. The length of the handle assembly 120 can be adjusted at any time during the ball valve opening and closing operation to adapt to the operating space requirements. The handle assembly 120 has a simple structure and is easy to manufacture.

[0043] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
