Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a five-way ball valve device. Background Technology

[0002] A ball valve is a type of valve that uses a spherical structure as its valve core for opening and closing control. Some ball valves employ multi-channel structures, such as three-way, four-way, or five-way ball valves. Due to their multi-channel design, these ball valves can flexibly control the merging, splitting, and switching of flow directions of the media, and can also close any channel while connecting the other two. For some existing five-way ball valves, designed for media containing fibers or small solid particles, their sealing structure typically uses a hard seal, where a ring-shaped metal seat abuts against the ball core. This structure is usually quite simple, and the sealing effect between the metal seat and the ball core is difficult to adjust after the metal seat is installed. It requires replacing the spring acting on the metal seat to change the abutment force between the metal seat and the ball core, which is cumbersome and inconvenient for production applications. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a five-way ball valve device, which can adjust the contact force between the metal valve seat and the ball core by rotating the adjusting ring, achieving a better contact sealing effect. It is simple and convenient to operate, and easy to apply in production.

[0004] According to an embodiment of this utility model, a five-way ball valve device includes a valve body assembly, a ball core, and a hard sealing structure. The valve body assembly has a valve core cavity and an input channel and an output channel communicating with the valve core cavity. The output channel is located on the lower side of the valve core cavity, and four output channels are provided and spaced apart around the periphery of the valve core cavity. The ball core is rotatably disposed in the valve core cavity. A valve stem passing through the valve body assembly is provided on the upper side of the ball core. The ball core has a connecting channel, one end of which is connected to the input channel, and the other end is used to connect to the output channel. The hard sealing structure is located in the output channel and includes an adjusting ring, a spring, and a metal valve seat. The metal valve seat is located on the side of the output channel closer to the ball core, and the adjusting ring is located on the side of the output channel away from the ball core. The outer side of the adjusting ring is threaded to the inner wall of the output channel. The spring is located between the adjusting ring and the metal valve seat and acts on the adjusting ring and the metal valve seat respectively.

The spring acts on the metal valve seat and makes it abut against the ball core, achieving a hard seal effect. During use, the ball core is rotatably set in the valve core cavity. By operating the valve stem to rotate, the ball core is driven to rotate, so that the connecting channel connects the input channel and one of the output channels, realizing the switching of the control medium flow direction. When it is necessary to adjust the abutting force between the metal valve seat and the ball core, the adjusting ring can be turned to move the adjusting ring closer to or further away from the ball core, changing the compression on the spring, thereby changing the force of the spring on the metal valve seat, changing the abutting force between the metal valve seat and the ball core, improving adaptability, which is conducive to achieving a better abutting seal effect. The operation is simple and convenient, and it is easy to produce and apply.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A five-way ball valve device includes a valve body assembly 100, a ball core 210, and a hard seal structure. The valve body assembly 100 has a valve core cavity 101 and an input channel 102 and an output channel 103 communicating with the valve core cavity 101. The output channels 103 are located on the lower side of the valve core cavity 101, and there are four output channels 103 distributed at intervals around the periphery of the valve core cavity 101. The ball core 210 is rotatably disposed in the valve core cavity 101. A valve stem 220 is provided on the upper side of the ball core 210 and passes through the valve body assembly 100. The ball core 210 has a connecting channel 201, one end of which is connected to the input channel 102. The other end is used to connect with the output channel 103. The hard seal structure is provided in the output channel 103 and includes an adjusting ring 310, a spring 320 and a metal valve seat 330. The metal valve seat 330 is provided on the side of the output channel 103 near the ball core 210. The adjusting ring 310 is provided on the side of the output channel 103 away from the ball core 210. The outer side of the adjusting ring 310 is threadedly engaged with the inner wall of the output channel 103. The spring 320 is provided between the adjusting ring 310 and the metal valve seat 330 and acts on the adjusting ring 310 and the metal valve seat 330 respectively. The metal valve seat 330 can abut against the ball core 210 under the action of the spring 320.

[0032] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the output channel 103 is located on the lower side of the valve core cavity 101. The four output channels 103 are respectively located on the front, rear, left, and right sides of the valve core cavity 101. The valve stem 220 is located on the upper side of the ball core 210 and passes through the valve body assembly 100. The ball core 210 is provided with a connection channel 201 that is approximately "L" shaped. One end of the connection channel 201 is connected to the input channel 102. As the ball core 210 rotates, the other end of the connection channel 201 is connected to the corresponding output channel 103. During production, the ball core 210 is installed into the valve core cavity 101. The metal valve seat 330, spring 320, and adjusting ring 310 are sequentially installed into the output channel 103. The adjusting ring 310 is screwed in through the threaded structure, so that the adjusting ring 310 and the metal valve seat 330 clamp the spring 320. The spring 320 exerts force on the metal valve seat 330 and makes it abut against the ball core 210, achieving a hard seal effect. During use, the ball core 210 is rotatably set in the valve core cavity 101. By rotating the operating valve stem 220, the ball core 210 is driven to rotate, so that the connecting channel 201 connects to the input channel. 102 and one of the output channels 103 enable the switching of the control medium flow direction; when it is necessary to adjust the abutment force between the metal valve seat 330 and the ball core 210, the adjusting ring 310 can be turned to move the adjusting ring 310 closer to or further away from the ball core 210, changing the compression on the spring 320, thereby changing the force of the spring 320 on the metal valve seat 330, changing the abutment force between the metal valve seat 330 and the ball core 210, improving adaptability, and helping to achieve a better abutment sealing effect. The operation is simple and convenient, and it is easy to use in production.

[0033] In practical applications, the specific structures of the valve body assembly 100, the adjusting ring 310, and the metal valve seat 330 can be set according to the actual needs of use. They will not be described in detail here, but will be explained in detail below.

[0034] In some embodiments, the metal valve seat 330 has a first extension 331 extending toward the adjusting ring 310 on the side facing the adjusting ring 310. The first extension 331 is annular and there is a gap between the outer side of the first extension 331 and the inner wall of the output channel 103. The spring 320 is sleeved on the outer side of the first extension 331. The adjusting ring 310 partially extends into the space between the outer side of the first extension 331 and the inner wall of the output channel 103.

[0035] Understandably, such as Figure 3As shown, the first extension 331 is located on the side of the metal valve seat 330 facing the adjusting ring 310 and is annular. A gap is provided between the outer side of the first extension 331 and the inner wall of the output channel 103, allowing the spring 320 to be fitted onto the outer side of the first extension 331 and located between the outer side of the first extension 331 and the inner wall of the output channel 103. The adjusting ring 310 partially extends into the space between the outer side of the first extension 331 and the inner wall of the output channel 103, forming an annular space to accommodate the spring 320. This helps protect the spring 320, reduces the impact of the medium in the output channel 103 on the spring 320, avoids contamination or damage to the spring 320, and ensures a good sealing effect. In practical applications, the first extension 331 can be adjusted according to actual usage requirements.

[0036] In some embodiments, a first sealing ring 311 is provided between the outer ring of the first extension 331 and the adjusting ring 310. It is understood that, as Figure 3 As shown, the first sealing ring 311 is disposed between the outer side of the first extension 331 and the adjusting ring 310 to seal the gap between them, which helps to prevent the medium from entering the space where the spring 320 is located and ensures the sealing effect. In this embodiment, one first sealing ring 311 is provided. In actual applications, multiple first sealing rings 311 can also be provided, which can be set according to the actual use needs.

[0037] In some embodiments, a second sealing ring 332 is provided between the outer ring of the metal valve seat 330 and the inner wall of the output channel 103. It is understood that, as Figure 3 As shown, during use, some medium may exist between the inner wall of the valve core cavity 101 and the outer wall of the ball core 210. By setting a second sealing ring 332, which is located between the outer ring of the metal valve seat 330 and the inner wall of the output channel 103, the gap between the two is sealed. This helps to prevent the medium from entering the space where the spring 320 is located, ensuring a sealing effect. In this embodiment, two second sealing rings 332 are provided. In actual applications, one, three, or more second sealing rings 332 can also be provided, depending on the actual needs of use.

[0038] In some embodiments, the adjusting ring 310 has a recessed position 301 on the side away from the ball core 210. The recessed position 301 is located on the inner side of the adjusting ring 310 and the inner contour of the recessed position 301 has a hexagonal shape.

[0039] Understandably, such as Figure 1 , Figure 2 and Figure 4As shown, by setting a recessed position 301, which is located inside the adjusting ring 310 and has a hexagonal inner shape, the adjusting ring 310 can be easily driven to rotate by inserting an Allen wrench (or other hexagonal part) into the recessed position 301. Its structure is simple and easy to operate. In practical applications, the recessed position 301 can be set according to actual usage needs.

[0040] In some embodiments, the valve body assembly 100 includes a valve body 110 and a valve cover 120. An input channel 102 and an output channel 103 are both disposed on the valve body 110. The valve cover 120 is detachably disposed on the valve body 110 and defines a valve core cavity 101 between the valve body 110 and the valve cover 120. A valve stem 220 passes through the valve body 110.

[0041] Understandably, such as Figure 1 , Figure 2 and Figure 5 As shown, the valve body assembly 100 adopts a split structure, with both the input channel 102 and the output channel 103 located on the valve body 110. The valve cover 120 is detachably mounted on the valve body 110 and defines the valve core cavity 101 between the valve body 110 and the valve cover 120. During production, the ball core 210 can be installed into the valve core cavity 101 first, and then the hard seal structure can be installed. Its structure is simple and convenient for production, assembly, and use. In practical applications, the valve body assembly 100 can also be a split structure on the left and right or a split structure on the front and back, depending on the actual use.

[0042] In some embodiments, the lower side of the ball core 210 is provided with a downwardly extending second extension 211, and the input channel 102 is provided with a stepped structure 111 corresponding to the second extension 211. The second extension 211 is annular and extends to the stepped structure 111 of the input channel 102. Graphite gaskets 130 are provided between the upper side of the ball core 210 and the valve cover 120, and between the lower side of the second extension 211 and the stepped structure 111 of the input channel 102.

[0043] Understandably, such as Figure 2 , Figure 3 and Figure 5 As shown, the second extension 211 is located on the lower side of the ball core 210 and is annular, extending to the stepped structure 111 of the input channel 102. This provides support and rotational engagement for the lower side of the ball core 210. Graphite gaskets 130 are provided between the upper side of the ball core 210 and the valve cover 120, and between the lower side of the second extension 211 and the stepped structure 111 of the input channel 102. Graphite's good lubricity and sealing properties reduce rotational contact wear between the ball core 210 and the valve cover 120, and between the lower side of the second extension and the stepped structure 111, achieving a good sealing effect and facilitating use. In practical applications, the graphite gaskets 130 can be adjusted according to actual usage requirements.

[0044] In some embodiments, a third sealing ring 230 is provided between the valve stem 220 and the valve cover 120, and between the outer side of the second extension 211 and the inner wall of the input channel 102. It is understood that, as Figure 3 As shown, third sealing rings 230 are provided between the valve stem 220 and the valve cover 120, and between the outer ring of the second extension 211 and the inner wall of the input channel 102. By providing the third sealing rings 230, the gaps between the valve stem 220 and the valve cover 120, and between the outer ring of the second extension 211 and the inner wall of the input channel 102, are sealed, which helps to ensure a sealing effect, reduce the possibility of media leakage, and facilitates use. In this embodiment, two third sealing rings 230 are provided at the valve stem 220 and two at the second extension 211. In actual applications, the specific number of third sealing rings 230 can be set according to actual usage needs.

[0045] In some embodiments, the valve body assembly 100 is provided with a purge channel 104, which can connect the valve core cavity 101 with the external environment. A sealing plug 140 is provided at the purge channel 104, which is detachably connected to the valve body assembly 100 and can block the purge channel 104.

[0046] Understandably, such as Figure 1 and Figure 5 As shown, the purge channel 104 runs through the inner and outer sides of the valve body assembly 100, allowing the valve core cavity 101 to connect to the external environment through the purge channel 104. During normal use, the sealing plug 140 seals the purge channel 104. When used with particulate media, some particulate media will exist between the inner wall of the valve core cavity 101 and the outer wall of the ball core 210. Moreover, as the usage time increases, the amount of particulate media between the inner wall of the valve core cavity 101 and the outer wall of the ball core 210 will gradually increase. This increase in the amount of particulate media will create resistance to the rotation of the ball core 210, resulting in an increase in the torque required for rotation. At this time, the sealing plug 140 can be removed from the purge channel 104, and then the suction pipe can be connected to the purge channel 104 to suction out some of the particulate media between the inner wall of the valve core cavity 101 and the outer wall of the ball core 210, thereby reducing the rotational resistance of the ball core 210, facilitating the operation of the ball core 210 rotation, and making it easier to use. In practical applications, the detachable connection between the sealing plug 140 and the valve body assembly 100 can be achieved through a threaded structure or other detachable structure, which can be set according to the actual needs of use.

[0047] In some embodiments, purge channels 104 are provided in multiple ways and are respectively distributed on the upper and lower sides of valve core cavity 101, and each purge channel 104 is provided with a sealing plug 140.

[0048] Understandably, such as Figure 1 and Figure 5 As shown, four purge channels 104 are provided. Two purge channels 104 are distributed on the upper side of the valve core cavity 101, and the other two purge channels 104 are distributed on the lower side of the valve core cavity 101. This facilitates the suction of particulate media accumulated at the upper and lower positions of the valve core cavity 101, making it convenient to use. In actual applications, the specific number and distribution of purge channels 104 can be set according to actual usage requirements.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
