Description

Technical Field

[0001] The present application relates to the technical field of sealing clamps, and in particular to a clamp and a sealing device. Background Art

[0002] Clamps, as a fastener, are used to connect two or more objects so that they form a whole and can withstand a certain load. Clamps are widely used in the pressure bearing and sealing of pipes and equipment in the fields of food processing, pharmaceuticals, bioengineering and other sanitary equipment manufacturing. Sanitary equipment has high requirements for the connection reliability, sealing and safety of clamps.

[0003] The two parts of the sealing device are connected by a clamp to form an integrated sealing device. In the related art, the clamp includes two semi-circular ring structures. After the two semi-circular ring structures are connected to the sealing device respectively, the clamp is locked by at least two sets of screws to form an integrated sealing device.

[0004] However, it is difficult to control the force balance of the semi-circular ring structures during the process of locking the two semi-circular ring structures separately. Especially when the clamp is applied to large-sized equipment, it is easy to have insufficient local locking force, which can easily lead to poor sealing effect of the equipment and internal leakage, thus easily affecting the normal operation and safety of the equipment. Summary of the invention

[0058] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0059] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0060] The clamp provided in the embodiment of the present application can be applied to a sealing device. The sealing device in the embodiment of the present application can be, but is not limited to, a sanitary sealing device. Sanitary sealing equipment mainly refers to equipment and systems with extremely high hygiene requirements. For example, applications in the pharmaceutical, food processing and other industries. The design and manufacture of sanitary sealing equipment must strictly follow high standards of hygiene requirements to ensure that the product is not contaminated and to ensure the purity and safety of the product.

[0061] Sanitary sealing equipment may include but is not limited to sanitary valves, sanitary pipes, sanitary containers, sanitary clamps, etc. The clamp provided in the embodiment of the present application may be used as a sanitary clamp in sanitary sealing equipment.

[0062] The inside of sanitary sealing equipment is in a sealed environment, and sanitary sealing equipment has high requirements for sealing. Especially for large-scale sanitary sealing equipment, due to its large size, if there are problems such as pressure relief, leakage and other poor sealing, it is easy to have safety hazards.

[0063] The sealing device may include at least two structures. The clamp, as a fastener for connecting the two structures, may affect the connection reliability, and thus may also easily affect the sealing effect. In the related art, the clamp includes two semi-circular ring structures. After the two semi-circular ring structures are respectively connected to the sealing device, the clamp is locked by at least two sets of screws to form a sealing device with an integrated structure.

[0064] However, in the process of locking the two semi-circular ring structures separately, it is difficult to control the force balance of the two semi-circular ring structures. Especially when the clamp is applied to large-sized equipment, it is easy to have insufficient local locking force, which can easily lead to poor sealing effect of the equipment. In addition, when it is necessary to open the sealing device, in the process of loosening the screws one by one, the screws loosened later are prone to bear greater forces, which can easily affect the service life of the screws. For example, the screws are prone to disengagement, which affects the locking force of the screws, thereby easily affecting the sealing effect of the sealing device and causing internal leakage, which can easily affect the normal operation and safety of the equipment.

[0065] Based on the above technical problems, an embodiment of the present application provides a clamp that can be used as a sanitary clamp to be applied to a sanitary sealing device. In an embodiment of the present application, the clamp includes an annular body with an opening. The annular body is an integral structure. Therefore, when the annular body is locked by a locking piece so that the first end and the second end of the annular body are close to each other, the force applied to the first end and the second end to approach each other can be transmitted along the circumference of the annular body, so that the annular body can be evenly gathered toward the center of the circle. The force on the annular body can be relatively uniform, thereby reducing the uneven force on the annular body and the uneven force on the locking force of the sealing device, which may affect the sealing effect of the sealing device.

[0066] When the sealing device needs to be opened, since the locking piece can be inserted through the first end and the second end, the first end and the second end can be gradually released during the unlocking process of the locking piece. The annular body can release its own elastic potential energy to move the two away from each other, so that the pressing force of the sealing device can be unlocked relatively evenly, which is beneficial to increase the service life of the locking piece and the annular body itself, and reduce the possibility of reducing the reliability of the locking piece and the annular body, which may affect the sealing effect of the sealing device.

[0067] The clamp 100 and the sealing device 10 provided in the present application are described below with reference to the accompanying drawings and in combination with specific embodiments.

[0068] See also Figures 1 to 5 As shown, the clamp 100 of the embodiment of the present application may include an annular body 110 and an adjustment assembly 120 .

[0069] The annular body 110 may be provided with a mounting portion 111. The mounting portion 111 may be used to connect the two parts of the device body 200. The annular body 110 has an opening, and has a first end 110a and a second end 110b at the opening. Among them, for the convenience of description, in the embodiment of the present application, the two parts of the device body 200 may refer to the first body 210 and the second body 220. The opening ends of the first body 210 and the second body 220 may be opposite. The annular body 110 may be arranged at the connection between the first body 210 and the second body 220, so as to keep the first body 210 and the second body 220 in a connected and locked state.

[0070] It is easy to understand that when the first end 110a and the second end 110b are close to each other, the mounting portion 111 of the annular body 110 can be clamped to the first body 210 and the second body 220, so that the first body 210 and the second body 220 can maintain a tightly connected state. When the first end 110a and the second end 110b are away from each other, the annular body 110 can be separated from at least one of the first body 210 and the second body 220, so that the first body 210 and the second body 220 can be separated, and the device body 200 can be in an openable state.

[0071] The adjustment assembly 120 may be disposed corresponding to the opening of the annular body 110. The adjustment assembly 120 may include a locking member 121. The locking member 121 may be disposed through the first end 110a and the second end 110b. The locking member 121 is used to move the first end 110a and the second end 110b closer or farther away to lock or unlock the annular body 110.

[0072] It is easy to understand that the clamp 100 can be elastic, so the first end 110a and the second end 110b can be driven to move closer to or farther from each other by the rotation of the locking element 121. For example, when the locking element 121 rotates forward, the first end 110a and the second end 110b can be moved closer to each other, so that the annular body 110 can lock the first body 210 and the second body 220. When the locking element 121 rotates reversely, the first end 110a and the second end 110b can be moved away from each other, so that the annular body 110 can unlock the first body 210 and the second body 220.

[0073] In some examples, the annular body 110 of the embodiment of the present application may have one opening. Correspondingly, the number of the locking piece 121 may also be one. Therefore, the clamp 100 can be locked or unlocked by one locking piece 121, which is simple in operation and helps to improve production efficiency.

[0074] In some examples, the opening may refer to a narrow port that circumferentially cuts off the annular body 110 . The first end 110 a and the second end 110 b are located at the opening, and thus, the first end 110 a and the second end 110 b may be opposite to each other along a tangent direction of the annular body 110 .

[0075] In some possible implementations, see Figure 3 and Figure 5 As shown, the locking member 121 of the embodiment of the present application may include a first threaded portion 1211 and a second threaded portion 1212. The first threaded portion 1211 may be used to cooperate with the first end 110a for movement. The second threaded portion 1212 may be used to cooperate with the second end 110b for movement. The first threaded portion 1211 and the second threaded portion 1212 have opposite rotation directions.

[0076] In the embodiment of the present application, since the first threaded portion 1211 is used to cooperate with the first end 110a, and the second threaded portion 1212 is used to cooperate with the second end 110b, by setting the first threaded portion 1211 and the second threaded portion 1212 to have opposite rotation directions, when the locking element 121 rotates, the movement directions of the first end 110a and the second end 110b can be opposite, thereby making the first end 110a and the second end 110b approach or move away from each other.

[0077] In some possible implementations, see Figure 3 and Figure 5 As shown, the locking member 121 of the embodiment of the present application may further include an operating portion 1213. The operating portion 1213 may be used to drive the locking member 121 to rotate forward or reversely. The operating portion 1213 may be located at at least one end of the locking member 121. The operating portion 1213 may also be located between the first threaded portion 1211 and the second threaded portion 1212.

[0078] In the embodiment of the present application, the operating portion 1213 is provided to facilitate a worker to clamp the operating portion 1213 through an operating tool to drive the locking member 121 to rotate.

[0079] In some examples, the operating portion 1213 may include at least one set of opposing operating surfaces. An operating tool may clamp the operating surfaces to drive the locking element 121 to rotate.

[0080] When the operating portion 1213 is located at the end of the locking member 121, a driving force can be applied to the end of the locking member 121. Since the operating portion 1213 is located at the end, the operating tool can be a socket wrench. When the operating portion 1213 is located between the first threaded portion 1211 and the second threaded portion 1212, a driving force can be applied to the middle area of ​​the locking member 121. Since the operating portion 1213 is located in the middle area, the operating tool can be a wrench.

[0081] In some examples, the operating tool may be an electric wrench. The torque of the electric wrench is adjustable, so the driving force on the locking element 121 can be adjusted by adjusting the torque of the operating tool to meet the force for locking or unlocking the annular body 110.

[0082] For some examples, see Figure 3 and Figure 5 As shown, a limiting protrusion 1214 may be provided on the outer wall of the locking member 121. The limiting protrusion 1214 may be located between the first threaded portion 1211 and the second threaded portion 1212. The limiting protrusion 1214 may be used to prevent the locking member 121 from being disengaged from the first end 110a or the second end 110b during the forward or reverse rotation of the locking member 121.

[0083] When an operating portion 1213 is provided between the first thread portion 1211 and the second thread portion 1212 , a limiting protrusion 1214 may be provided on a side of the operating portion 1213 close to the first thread portion 1211 , and a limiting protrusion 1214 may also be provided on a side of the operating portion 1213 close to the second thread portion.

[0084] In some possible implementations, see Figures 3 to 5 As shown, the adjustment assembly 120 may include a first fixing nut 122. The first fixing nut 122 may be disposed at the first end 110a of the annular body 110. The locking member 121 may be inserted through the first fixing nut 122. The first threaded portion 1211 of the locking member 121 cooperates with the first fixing nut 122. The adjustment assembly 120 may include a second fixing nut 123. The second fixing nut 123 may be disposed at the second end 110b of the annular body 110. The locking member 121 may be inserted through the second fixing nut 123. The second threaded portion 1212 of the locking member 121 cooperates with the second fixing nut 123.

[0085] In the embodiment of the present application, the first end 110a may be provided with a first fixing nut 122 for cooperating with the first threaded portion 1211 of the locking member 121. The second end 110b may be provided with a second fixing nut 123 for cooperating with the second threaded portion 1212 of the locking member 121. The internal threads of the first fixing nut 122 and the second fixing nut 123 have opposite rotation directions, so that when the locking member 121 is driven to rotate forward or reverse, the first end 110a and the second end 110b can be driven to move in opposite directions, thereby locking or unlocking the annular body 110.

[0086] In some examples, the first end 110a may include an adapter 124. The adapter 124 may be used to fix the first fixing nut 122 to the annular body 110. Alternatively, the second end 110b may also include an adapter 124. The adapter 124 may be used to fix the second fixing nut 123 to the annular body 110.

[0087] Exemplarily, the first fixing nut 122 and the second fixing nut 123 can be respectively fixed to the first end 110a and the second end 110b of the annular body 110 through the adapter 124. Taking the first fixing nut 122 as an example, the adapter 124 may include a first adapter plate 1241 and a second adapter plate 1242 that are opposite to each other along the axial direction of the annular body 110. The first adapter plate 1241 and the second adapter plate 1242 may be arranged at intervals. The first fixing nut 122 may be in a columnar structure. One end of the first fixing nut 122 may be connected to the first adapter plate 1241, and the other end of the first fixing nut 122 may be connected to the second adapter plate 1242. For example, the first fixing nut 122 may be inserted into the first adapter plate 1241 and the second adapter plate 1242. The first adapter plate 1241 and the second adapter plate 1242 may be used to stably support the first fixing nut 122 during the rotation of the locking member 121. The axis of the column structure of the first fixing nut 122 may be perpendicular to the axis of the internal thread of the first fixing nut 122 .

[0088] In some examples, the threaded portion of the first fixing nut 122 may be located between the first adapter plate 1241 and the second adapter plate 1242. When the fastener 121 passes through the first end 110a and the second end 110b, a portion of the fastener 121 may be located between the first adapter plate 1241 and the second adapter plate 1242.

[0089] In some examples, the adapter 124 may be fixed to the annular body 110 by welding, but is not limited thereto. The first fixing nut 122 may be fixed to the first adapter plate 1241 and the second adapter plate 1242 by crimping, riveting, welding, or the like, but is not limited thereto.

[0090] In some possible implementations, see Figure 2 and Figure 7 As shown, the clamp 100 may further include a first fixing member 150. The first fixing member 150 may be disposed on the annular body 110. The first fixing member 150 is used to be connected to the device body 200. The first fixing member 150 and the opening may be opposite to each other along the radial direction of the annular body 110.

[0091] In the embodiment of the present application, the annular body 110 can be connected to the device body 200 through the first fixing member 150. Since the first fixing member 150 and the opening are arranged opposite to each other along the radial direction of the annular body 110, when the locking member 121 is adjusted to make the first end 110a and the second end 110b approach or move away from each other, the first fixing member 150 can remain in a fixed state. Therefore, the forces on the annular body 110 from the first end 110a to the first fixing member 150 and the forces on the second end 110b to the first fixing member 150 can be relatively balanced, which is beneficial to improving the service life of the clamp 100 on the one hand, and on the other hand, it is beneficial to improve the sealing uniformity of the clamp 100 to the sealing device 10 and improve the sealing effect.

[0092] In some possible implementations, see Figure 2 and Figure 5 As shown, the clamp 100 may further include a first limiting portion 140. The first limiting portion 140 may be slidably connected to the device body 200. The first limiting portion 140 may be used to restrict the range of motion of the first end 110a and the second end 110b.

[0093] In the embodiment of the present application, since the locking member 121 can be used to drive the first end 110a and the second end 110b to move closer to or away from each other, in order to avoid the first end 110a and the second end 110b being infinitely far apart, which increases the difficulty of subsequent sealing and locking operations, the maximum path of relative sliding between the first limiting portion 140 and the device body 200 can be used to constrain the maximum movement range of the first end 110a and the second end 110b.

[0094] In some examples, since the first limiting portion 140 is slidably connected to the device body 200, the first limiting portion 140 can also be used to connect the annular body 110 to the device body 200. The first limiting portion 140 can be used together with the first fixing member 150 to connect the annular body 110 to the device body 200, thereby improving the connection reliability of the annular body 110 and the device body 200.

[0095] There may be a plurality of first limiting portions 140. The plurality of first limiting portions 140 may be symmetrically distributed relative to a line connecting the first fixing member 150 and the opening.

[0096] In some possible implementations, see Figure 3 As shown, the clamp 100 may further include a first locking portion 131 and a second locking portion 132. The first locking portion 131 and the second locking portion 132 may be respectively disposed at the first end 110a and the second end 110b. The first locking portion 131 and the second locking portion 132 cooperate to move to lock the first end 110a and the second end 110b.

[0097] During the process of adjusting the locking member 121 to bring the first end 110a and the second end 110b closer or farther away from each other, the first locking portion 131 and the second locking portion 132 may also generate relative movement. For example, when the first end 110a and the second end 110b are brought closer to each other so that the first locking portion 131 and the second locking portion 132 reach a preset position, the first end 110a and the second end 110b can be kept relatively still, so that the first end 110a and the second end 110b can be locked, so that the clamp 100 can maintain a state of sealing the sealing device 10.

[0098] In some possible implementations, see Figure 4 and Figure 5 As shown, the first locking portion 131 and the second locking portion 132 may have a gap along the radial direction of the annular body 110. The first locking portion 131 may be provided with a first locking groove 131a. The second locking portion 132 may be provided with a second locking groove 132a.

[0099] When the first locking groove 131 a and the second locking groove 132 a are aligned along the radial direction of the annular body 110 , the first locking groove 131 a and the second locking groove 132 a can be used to lock with the structure on the device body 200 to lock the first locking portion 131 and the second locking portion 132 .

[0100] When the first locking groove 131a and the second locking groove 132a are opposite to each other, the structure on the device body 200 can be located in the first locking groove 131a and the second locking groove 132a. At this time, the inner wall of the first locking groove 131a and the structure on the device body 200 can constrain each other, so that the first locking portion 131 is limited by the locking member 133, so that the first end 110a is kept still by the first locking portion 131. Similarly, when the structure on the device body 200 is located in the second locking groove 132a, the inner wall of the second locking groove 132a and the structure on the device body 200 can constrain each other, so that the second locking portion 132 is limited by the structure on the device body 200, so that the second end 110b is kept still.

[0101] The present application also provides a sealing device 10, see Figure 1 As shown, the sealing device 10 may include a device body 200 and the clamp 100 in any of the above embodiments.

[0102] The device body 200 includes a first body 210 and a second body 220. The first body 210 can cover the second body 220. The outer periphery of the first body 210 can be provided with a first flange 211. The outer periphery of the second body 220 can be provided with a second flange 221 corresponding to the first flange 211. The clamp 100 can be connected to the first flange 211 and the second flange 221 through the mounting portion 111.

[0103] In the embodiment of the present application, when the first body 210 covers the second body 220, the first flange 211 may correspond to the second flange 221. The first flange 211 and the second flange 221 may provide installation positions for the clamp 100.

[0104] Specifically, the first flange 211 may protrude from the outer wall of the first body 210. The second flange 221 may protrude from the outer wall of the second body 220. The mounting portion 111 may be disposed on the inner wall of the annular body 110. The mounting portion 111 may be a recessed structure. The opening of the mounting portion 111 may face the first flange 211 and the second flange 221. At least a portion of the first flange 211 and the second flange 221 may be located in the mounting portion 111 of the annular body 110, so that the mounting portion 111 and the first flange 211 and the second flange 221 may be in full contact, so that when the annular body 110 is in a locked state, the first flange 211 and the second flange 221 may be closely connected through the annular body 110.

[0105] In some examples, one of the first flange 211 and the second flange 221 may be provided with a groove for accommodating a seal. The seal is located in the groove, and when the annular body 110 locks the first flange 211 and the second flange 221, the seal may be pressed between the first body 210 and the second body 220, thereby achieving a sealed connection between the first body 210 and the second body 220.

[0106] In some examples, the first flange 211 and the first body 210 may be an integral structure, or the first flange 211 may form an integral, non-detachable structure with the first body 210 by welding or the like. The second flange 221 and the second body 220 may be an integral structure, or the second flange 221 may form an integral, non-detachable structure with the second body 220 by welding or the like.

[0107] In some examples, the sealing device 10 may be a sanitary device. A chemical reaction may occur in the sealing device 10. Therefore, the first body 210 and the second body 220 may be made of a material that is not easily corroded, such as stainless steel, and the inner walls of the first body 210 and the second body 220 may be finely processed to reduce bacterial growth and cleaning difficulty.

[0108] In some achievable embodiments, the sealing device 10 further includes a locking member 133. The locking member 133 can be used to cooperate with the first locking portion 131 and the second locking portion 132 to move, so as to lock the first end 110a and the second end 110b. The locking member 133 can be used to be movably connected to the device body 200, and the locking member 133 has a first state and a second state. The locking member 133 can be used to lock the first locking portion 131 and the second locking portion 132 in the first state. And, the locking member 133 can be used to unlock the first locking portion 131 and the second locking portion 132 in the second state.

[0109] In the embodiment of the present application, since the first locking portion 131 is disposed at the first end 110a and the second locking portion 132 is disposed at the second end 110b, the first locking portion 131 and the first end 110a of the annular body 110 can move synchronously, and the second locking portion 132 and the second end 110b of the annular body 110 can move synchronously. Therefore, the first locking portion 131 and the second locking portion 132 can be locked by the locking member 133 in the first state, so that the first end 110a and the second end 110b remain in a stationary state, so that when the locking member 121 makes the annular body 110 in a locked state, the locking member 133 can perform a secondary locking on the first locking portion 131 and the second locking portion 132. The locking member 133 and the first locking portion 131 and the second locking portion 132 are mutually constrained, so that relative movement between the locking member 133, the first locking portion 131 and the second locking portion 132 is not easy to occur. In other words, the first locking portion 131 and the second locking portion 132 can remain relatively still, and therefore, the first end 110a and the second end 110b of the annular body 110 can also remain relatively still, so that the annular body 110 remains in a locked state.

[0110] It is easy to understand that when the locking member 133 is in the first state, it is difficult to operate the locking member 121 to drive the first end 110a and the second end 110b to move, and the annular body 110 is still in a locked state. When the device body 200 needs to be opened, the locking member 133 needs to be in the second state first to unlock the first locking portion 131 and the second locking portion 132, and then the locking member 121 can be operated to unlock the locking force of the annular body 110 on the first body 210 and the second body 220.

[0111] In summary, the coordinated movement of the first locking portion 131, the second locking portion 132 and the locking member 133 can be used to improve the connection reliability of the first body 210 and the second body 220, so that when the locking force of the locking member 121 is insufficient, the first body 210 and the second body 220 are locked by the locking member 133 and the first locking portion 131 and the second locking portion 132, so as to reduce the possibility that the first body 210 and the second body 220 are not locked due to the insufficient locking force of the locking member 121, and the sealing of the device body 200 fails, thereby affecting the normal operation of the device body 200. In addition, if the sealing problem of the large-sized device body 200 is poor, the rapid pressure release of the device body 200 is likely to cause safety hazards. Therefore, the connection reliability of the first body 210 and the second body 220 can be improved, which is conducive to ensuring the sealing effect of the first body 210 and the second body 220, so as to maintain the safe operation of the device body 200.

[0112] In addition, during the locking process of the locking element 121, there is an interaction force between the locking element 121 and the first end 110a and the second end 110b. That is, when the locking element 121 drives the first end 110a and the second end 110b to approach each other, the locking element 121 can be subjected to the force applied by the first end 110a and the second end 110b. When applied to a device body 200 with a larger size, the force borne by the locking element 121 is also larger. In the embodiment of the present application, by locking the locking member 133 with the first locking portion 131 and the second locking portion 132, it can be used to share part of the force borne by the locking element 121, which is beneficial to increase the service life of the locking element 121.

[0113] In some examples, the manner in which the locking member 133 locks the first locking portion 131 and the second locking portion 132 is not limited in this embodiment. The manner in which the locking member 133 cooperates with the first locking portion 131 and the manner in which the locking member 133 cooperates with the second locking portion 132 may be the same or different, and is not limited in this embodiment.

[0114] Exemplarily, when the locking member 133 is in the first state, the locking member 133 contacts the first locking portion 131 and the second locking portion 132, so that the first locking portion 131 and the second locking portion 132 remain stationary relative to the locking member 133. When the locking member 133 is in the second state, the locking member 133 does not contact the first locking portion 131 and the second locking portion 132, so that the first locking portion 131 and the second locking portion 132 can be displaced. For example, the locking member 133 and the first locking portion 131 and the second locking portion 132 can be, but are not limited to, plugged or snapped together.

[0115] In some examples, the manner in which the locking member 133 is movably connected to the device body 200 is not limited in this embodiment. For example, the locking member 133 may be movably connected to the device body 200 via a rotating shaft.

[0116] In some possible implementations, see Figures 3 to 5 As shown, the sealing device of the embodiment of the present application may further include a safety valve 134. The safety valve 134 may be disposed in the device body 200 and communicated with the internal space of the device body 200. The locking member 133 is connected to the safety valve 134 and is used to control the opening or closing of the safety valve 134. When the locking member 133 is in the first state, the safety valve 134 is closed. When the locking member 133 is in the second state, the safety valve 134 is opened.

[0117] Among them, on the one hand, the safety valve 134 can be used to improve the safety of the device body 200. For example, when the pressure in the device body 200 is too high, the internal pressure can be released through the safety valve 134 to protect the internal structure of the device body 200, and it can also reduce the potential safety hazard caused by the inability to release the pressure in the device body 200. Since the locking member 133 is connected to the safety valve 134, the locking member 133 can be used to control the opening or closing of the safety valve 134.

[0118] On the other hand, since the locking member 133 can be used to lock the first locking portion 131 and the second locking portion 132, and the locking member 133 is connected to the safety valve 134, the locking member 133 can be used to control the opening or closing of the safety valve 134, and can also be used to maintain the locking state of the annular body 110 when the locking member 121 locks the annular body 110, thereby improving the reliability of the sealing connection between the first body 210 and the second body 220. In addition, since the locking control of the safety valve 134 and the annular body 110 can be achieved through one component, namely the locking member 133, it is possible to save components, reduce the processing and assembly costs of components, and simplify the operation steps of the clamp 100.

[0119] On the other hand, the locking member 133 and the locking member 121 can be used to control the opening or closing of the safety valve 134 .

[0120] Specifically, the locking member 133 can be movably connected to the safety valve 134. The safety valve 134 is provided on the device body 200. When the locking member 133 is in the first state, the locking member 133 can lock the first locking portion 131 and the second locking portion 132. At this time, the safety valve 134 can be in a closed state so that the device body 200 is in a sealed state, and the device body 200 can operate normally. When the device body 200 needs to be opened, the locking member 133 can be operated in the second state to unlock the first locking portion 131 and the second locking portion 132. At this time, the safety valve 134 can be in an open state to assist the device body 200 in releasing the internal pressure.

[0121] In some examples, the safety valve 134 may include a housing (not shown) and a valve body (not shown). The valve body may move relative to the housing. The locking member 133 is connected to the valve body and may be used to drive the valve body to move in the housing so as to make the internal space of the device body 200 communicate with or not communicate with the external environment by changing the position of the valve body or setting the angle. When the locking member 133 is in a first state, the locking member 133 may drive the valve body to be in a state of closing the housing. The valve body may block the internal space of the device body 200 from communicating with the external environment. When the locking member 133 is in a second state, the locking member 133 may drive the valve body to be in an open state, and the internal space of the device body 200 may be communicated with the external environment.

[0122] For some examples, see Figure 4 As shown, the sealing device 10 may further include a connector 135 and a vertebral body pipeline 136. The vertebral body pipeline 136 may be disposed on the first body 210 or the second body 220. This embodiment is described by taking the vertebral body pipeline 136 disposed on the first body 210 as an example. The vertebral body pipeline 136 may be connected to the internal space of the device body 200. The safety valve 134 may be connected to the vertebral body pipeline 136 via the connector 135. Therefore, the internal space of the device body 200, the vertebral body pipeline 136, the connector 135 and the safety valve 134 are connected.

[0123] One end of the connector 135 may be connected to the vertebral body pipeline 136. The other end of the connector 135 may be connected to the safety valve 134. It should be noted that the connector 135 is sealed to the vertebral body pipeline 136, and the connector 135 is also sealed to the safety valve 134. The sealed connection may be, but is not limited to, a sealing ring is used to seal the connector 135, the vertebral body pipeline 136, and the safety valve 134.

[0124] In some examples, the connector 135 can be a clamp 100. For example, the connector 135 can be sleeved on the outside of a portion of the vertebral body pipeline 136 and a portion of the safety valve 134, and then locked by screws to ensure that the vertebral body pipeline 136 and the safety valve 134 are sealed and reliably connected.

[0125] In some examples, the cone tube 136 has a large opening end and a small opening end, wherein the large opening end can be used to connect with the first body 210, so that when the interior of the device body 200 is cleaned, it is not easy for stains or cleaning liquid to remain through the large opening. The small opening end of the cone tube 136 can be used to connect with the safety valve 134 through the connector 135. The small opening end can prevent the cleaning liquid from entering the safety valve 134 when the interior of the device body 200 is cleaned.

[0126] In some examples, the vertebral tube 136 can be fixed to the first body 210 by welding, but is not limited to it.

[0127] In some examples, the sealing device 10 may further include an exhaust pipe 137. The exhaust pipe 137 may be disposed at an end of the safety valve 134 away from the cone pipe 136. The gas in the device body 200 is released through the exhaust pipe 137 to relieve the pressure of the device body 200. The medium discharged through the exhaust pipe 137 may be a gas or a gas-liquid mixture.

[0128] In some examples, the exhaust duct 137 may be a curved pipe structure. The curved pipe structure may be used to guide the direction of movement of the discharged medium. For example, the outlet of the exhaust duct 137 may be oriented upward to prevent the medium inside the device body 200 from being directed toward the staff when the pressure is released, thereby causing a safety hazard.

[0129] In some possible implementations, see Figure 4 and Figure 5 As shown, the first locking portion 131 of the embodiment of the present application may be provided with a first locking groove 131a, and the second locking portion 132 may be provided with a second locking groove 132a.

[0130] When the locking member 133 is in the first state, the first locking groove 131a and the second locking groove 132a can be opposite to each other. The locking member 133 can be located in the first locking groove 131a and the second locking groove 132a to lock the first locking portion 131 and the second locking portion 132. When the locking member 133 is in the second state, the locking member 133 can be disengaged from the first locking groove 131a and the second locking groove 132a to unlock the first locking portion 131 and the second locking portion 132.

[0131] In the embodiment of the present application, when the locking member 133 is in the first state, part of the locking member 133 may be located in the first locking groove 131a, and part of the locking member 133 may be located in the second locking groove 132a. Taking the first locking groove 131a as an example, when the locking member 133 is located in the first locking groove 131a, the inner wall of the first locking groove 131a and the locking member 133 may constrain each other, so that the first locking portion 131 is limited by the locking member 133, so that the first end 110a is kept still by the first locking portion 131. Similarly, when the locking member 133 is located in the second locking groove 132a, the inner wall of the second locking groove 132a and the locking member 133 may constrain each other, so that the second locking portion 132 is limited by the locking member 133, so that the second end 110b is kept still by the second locking portion 132.

[0132] Moreover, in the embodiment of the present application, the first locking groove 131a and the second locking groove 132a may be opposite to each other. Therefore, when the locking member 133 is located in the first locking groove 131a and the second locking groove 132a at the same time, the first end 110a and the second end 110b may be limited.

[0133] In some examples, the first locking groove 131a may have an opening into which the locking member 133 may enter. The second locking groove 132a may also have an opening into which the locking member 133 may enter.

[0134] In some examples, the extension direction of the first locking groove 131a may be the same as the movement direction of the locking member 133. The locking member 133 may move a distance in the first locking groove 131a to prevent the locking member 133 from being dislodged from the first locking groove 131a. The extension direction of the second locking groove 132a may be the same as the movement direction of the locking member 133. The locking member 133 may move a distance in the second locking groove 132a to prevent the locking member 133 from being dislodged from the second locking groove 132a.

[0135] In some examples, one end of the locking member 133 may be connected to the safety valve 134, and the other end of the locking member 133 may move relative to the end connected to the safety valve 134. The movement direction of the locking member 133 is not limited in the embodiment of the present application. For example, the end of the locking member 133 away from the safety valve 134 may move up and down to facilitate the staff to apply force. The staff may press down the locking member 133 to lock the first locking portion 131 and the second locking portion 132. The staff may lift the locking member 133 upward to unlock the first locking portion 131 and the second locking portion 132.

[0136] In some examples, the width of the first locking groove 131a and the second locking groove 132a may be greater than or equal to the size of the locking member 133. It should be noted that the width of the first locking groove 131a and the second locking groove 132a may be slightly greater than the size of the locking member 133, so that when the locking member 133 is smoothly inserted into the first locking groove 131a and the second locking groove 132a, the locking member 133 is not easy to shake in the first locking groove 131a and the second locking groove 132a.

[0137] In some examples, the locking member 133 may include a rod structure. The rod structure of the locking member 133 may be used to snap into the first locking groove 131a and the second locking groove 132a. The rod structure may be convenient for the staff to hold.

[0138] In some possible implementations, see Figure 4 As shown, the first locking portion 131 and the second locking portion 132 may have a gap in the radial direction of the annular body 110. When the locking member 133 is in the first state, the first locking groove 131a and the second locking groove 132a may be aligned in the radial direction of the annular body 110.

[0139] In the embodiment of the present application, when the locking member 121 is locked or unlocked, the first end 110a and the second end 110b move closer or farther away from each other along the circumferential direction of the annular body 110. By setting the first locking portion 131 and the second locking portion 132 to have a radial interval, the first locking portion 131 and the second locking portion 132 are unlikely to collide when the first end 110a and the second end 110b respectively drive the first locking portion 131 and the second locking portion 132 to move closer to each other.

[0140] When the first locking groove 131 a and the second locking groove 132 a are aligned along the radial direction of the annular body 110 , the locking member 133 can be simultaneously inserted into the first locking groove 131 a and the second locking groove 132 a to keep the device body 200 in a sealed and locked state.

[0141] In some examples, the structures of the first locking portion 131 and the second locking portion 132 are not limited in the embodiments of the present application. For example, the first locking portion 131 and the second locking portion 132 may be plate-like structures. The first locking portion 131 may be fixed to the first end 110a of the annular body 110 by welding, but not limited thereto, and the second locking portion 132 may be fixed to the second end 110b of the annular body 110 by welding, but not limited thereto.

[0142] In some possible implementations, see Figure 2 and Figure 5As shown, the annular body 110 of the embodiment of the present application may be provided with a first limiting portion 140. The device body 200 may be provided with a second limiting portion 212. The first limiting portion 140 may be provided with a limiting slide groove 140a. The second limiting portion 212 may be slidably connected to the limiting slide groove 140a. The limiting slide groove 140a may be used to constrain the range of motion of the first end 110a and the second end 110b.

[0143] In the embodiment of the present application, since the locking piece 121 can be used to drive the first end 110a and the second end 110b to move closer to or away from each other, the second limiting portion 212 can slide in the limiting groove 140a of the first limiting portion 140 to constrain the maximum movement range of the first end 110a and the second end 110b, thereby reducing the possibility of the first end 110a and the second end 110b being infinitely far apart, resulting in an increase in the stroke of the subsequent locking movement and an increase in the difficulty of the operation.

[0144] In some examples, the limiting slide groove 140a can extend along the circumference of the annular body 110. Among them, the number of the first limiting portion 140 and the second limiting portion 212 can be multiple. The first limiting portion 140 and the second limiting portion 212 are used in conjunction with each other. Multiple first limiting portions 140 and second limiting portions 212 can be limited at multiple positions of the annular body 110. For example, see Figure 2 As shown, the number of the first limiting portion 140 and the second limiting portion 212 may be four.

[0145] In some possible implementations, see Figure 2 and Figure 6 As shown, the annular body 110 of the embodiment of the present application is provided with a first fixing member 150. The sealing device 10 may further include a second fixing member 213 and a connecting member 300. The connecting member 300 may be used to connect the first fixing member 150 and the second fixing member 213 so that the clamp 100 is fixed to the device body 200.

[0146] In the embodiment of the present application, the first fixing member 150, the second fixing member 213 and the connecting member 300 can be used to preliminarily fix the annular body 110 on the device body 200. Then, the first end 110a and the second end 110b of the annular body 110 can be brought close to each other through the locking member 121, so that the annular body 110 can lock the first flange 211 and the second flange 221.

[0147] In some examples, the process of connecting the first body 210 and the second body 220 of the clamp 100 may be, first, the mounting portion 111 of the annular body 110 is aligned with the first flange 211 and the second flange 221. Then, the first fixing member 150 and the second fixing member 213 may be aligned, and connected to the first fixing member 150 and the second fixing member 213 through the connecting member 300 to complete the preliminary fixing of the clamp 100. It should be noted that when the connecting member 300 is connected to the first fixing member 150 and the second fixing member 213, the second limiting portion 212 may be located in the limiting slide groove 140a. Then, the annular body 110 may be locked by the locking member 121 so that the annular body 110 locks the first flange 211 and the second flange 221. Finally, the locking member 133 is clamped into the first locking portion 131 and the second locking portion 132 to achieve sealing of the device body 200.

[0148] In some examples, the first fixing member 150 may be disposed on the first body 210. One of the second fixing member 213 and the connecting member 300 may be a screw, and the other of the second fixing member 213 and the connecting member 300 may be a nut. For example, the second fixing member 213 is a nut, and the connecting member 300 is a screw. The first fixing member 150 may be provided with a through hole through which the connecting member 300 may pass. Therefore, the connecting member 300 may pass through the through hole of the first fixing member 150 to be locked and connected with the second fixing member 213.

[0149] In some examples, the connecting member 300 can be used to connect the first fixing member 150 and the second fixing member 213, so that the clamp 100 is connected to the first body 210. In addition, since the second limiting portion 212 can slide in the limiting slide groove 140a of the first limiting portion 140, the second limiting portion 212 is connected to the first limiting portion 140, and the second limiting portion 212 can also have the function of connecting the first body 210 and the first limiting portion 140, so that the clamp 100 can be connected to the first body 210 to improve the connection stability of the clamp 100 and the first body 210. Therefore, when the first body 210 is lifted upward, the clamp 100 and the first body 210 are synchronously moved upward, so that the first body 210 and the second body 220 are completely separated.

[0150] In some examples, the process of opening the first body 210 and the second body 220 may be, first, disengaging the locking member 133 from the first locking portion 131 and the second locking portion 132 to unlock the first locking portion 131 and the second locking portion 132. Then, the locking member 121 may be operated to rotate so that the first end 110a and the second end 110b of the annular body 110 may be away from each other. At this time, the inner diameter of the annular body 110 may be greater than the outer diameters of the first flange 211 and the second flange 221. The annular body 110 may be separated from the first flange 211 and the second flange 221. Since the connecting member 300 is connected to the first fixing member 150 and the second fixing member 213, and the second limiting portion 212 is located in the limiting groove 140a of the first limiting portion 140, the annular body 110 can maintain a connected state with the first flange 211 on the first body 210, and the annular body 110 and the second flange 221 on the second body 220 can be separated to separate the first body 210 from the second body 220, and the equipment main body 200 can be in an open state.

[0151] It is easy to understand that in the embodiment of the present application, the operation method of connecting or separating the first body 210 and the second body 220 by the clamp 100 is simple, especially when applied to a large-sized sealing device 10, it can save time and effort while maintaining the locking force. In addition, it should be noted that when the first body 210 and the second body 220 are in a sealed or separated state, the clamp 100 can always remain fixed on the first body 210, so that the installation process of fixing the clamp 100 to the first body 210 again can be saved in the subsequent sealing process.

[0152] In some examples, along the radial direction of the annular body 110, the positions of the first fixing member 150, the second fixing member 213 and the connecting member 300 may be opposite to the opening of the annular body 110. In other words, the first end 110a and the second end 110b may be located on both sides of the first fixing member 150, respectively, and the position of the first fixing member 150 on the annular body 110 may be located in the middle area between the first end 110a and the second end 110b.

[0153] In some possible implementations, see Figure 2 and Figure 7 As shown, the first flange 211 may be provided with a first positioning plate 214. The first positioning plate 214 may be located at the opening. The second flange 221 may be provided with a second positioning plate 222 corresponding to the first positioning plate 214. One of the first positioning plate 214 and the second positioning plate 222 is protrudingly provided with a positioning pin 215, and the other of the first positioning plate 214 and the second positioning plate 222 is provided with a limiting hole 222a for the positioning pin 215 to pass through.

[0154] In the embodiment of the present application, the positioning pins 215 can be provided to position the first flange 211 and the second flange 221 .

[0155] Specifically, taking the positioning pin 215 being provided on the first positioning plate 214 as an example, the positioning pin 215 of the first positioning plate 214 can correspond to the limiting hole 222a on the second positioning plate 222. Therefore, when the first body 210 and the second body 220 are close to each other, the positioning pin 215 can penetrate into the limiting hole 222a. Through the mutual cooperation between the positioning pin 215 and the limiting hole 222a, the first body 210 and the second body 220 can be aligned to avoid misalignment between the two and affect the sealing of the device body 200.

[0156] In some examples, the limiting hole 222a may be a polygonal hole such as a square hole. The cross-sectional shape of the positioning pin 215 may be the same as the shape of the limiting hole 222a.
