[0022] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and not intended to limit the present invention.

[0023] In order to further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0024] The present application provides a linkage control device, which is mainly applied to a tank container and is used for the linkage between the loading and unloading valve and the gas phase valve of the tank body.

[0025] Refer to Figure 1 andFigure 2 The linkage control device 1 includes a follower 111, a power output member 121, and a linkage unit 13. Among them, the power output member 121 is arranged on the loading and unloading valve 2, and the power output member 121 can move with the rotation of the valve stem 21 of the loading and unloading valve 2 to output power outward. The follower 111 is fixed on the valve stem 31 of the gas phase valve 3 and can drive the valve stem 31 of the gas phase valve 3 to rotate. The linkage unit 13 includes a guide member 131 and a linkage member 132. The guide member 131 is provided with a guide channel, and the guide channel extends from the loading and unloading valve 2 to the gas phase valve 3. The guide member 131 is fixed relative to the tank body, and the linkage member 132 is inserted into the guide channel. One end of the linkage member 132 is connected to the power output member 121, and the other end is connected to the follower 111.

[0026] When the valve stem 21 of the loading and unloading valve 2 rotates under the action of an external force, the power output member 121 moves and outputs power to the linkage member 132 to drive the linkage member 132 to move along the guide channel; the linkage member 132 drives the follower 111 to drive the valve stem 31 of the gas phase valve 3 to rotate, thereby opening or closing the gas phase valve 3.

[0027] Further, in this embodiment, a housing 122 is provided outside the power output member 121. The housing 122 is arranged on the loading and unloading valve 2 and is arranged close to the valve stem 21 of the loading and unloading valve 2. The power output member 121 is arranged inside the housing 122, and the power output member 121 in this embodiment is a swing rod.

[0028] Specifically, one end of the swing rod is fixed on the valve stem 21 of the loading and unloading valve 2, and the other end is connected to the end of the linkage member 132. When the valve stem 21 of the loading and unloading valve 2 rotates under the action of an external force, the swing rod can rotate with the rotation of the valve stem 21 of the loading and unloading valve 2. The rotating swing rod can pull or push the linkage member 132. Since the linkage member 132 is a flexible structure with a certain hardness, the pulling of the swing rod can make the linkage member 132 move in the guide member 131, so that the other end of the linkage member 132 pulls or pushes the follower 111 to drive the valve stem 31 of the gas phase valve 3 to rotate, and the gas phase valve 3 is opened or closed.

[0029] In this embodiment, the linkage member 132 includes a steel wire rope 133 and connecting rods 134 arranged at both ends of the steel wire rope 133. Both ends of the steel wire rope 133 are correspondingly connected to the follower 111 and the power output member 121 through two connecting rods 134 respectively. When the swing rod rotates with the valve stem 21 of the loading and unloading valve 2, the swing rod can transmit the pulling force or pushing force to the steel wire rope 133 through the connecting rod 134 at one end, and then the connecting rod 134 at the other end of the steel wire rope 133 transmits the force to the follower 111, thereby driving the valve stem 31 of the gas phase valve 3 to rotate.

[0030] The hardness of the connecting rod 134 is greater than that of the wire rope 133. The wire rope 133 is connected to the power output member 121 and the follower member 111 through the connecting rod 134 with a greater hardness, which can effectively overcome the defect of insufficient thrust of the wire rope 133 during the force transmission process to ensure that the gas phase valve 3 is opened or closed in a timely manner.

[0031] Furthermore, the guiding member 131 of this embodiment includes a guiding sleeve 14 and connecting sleeves 15 connected to both ends of the guiding sleeve 14. Among them, the guiding sleeve 14 is sleeved outside the wire rope 133, and the connecting sleeve 15 is sleeved outside the connecting rod 134. In this embodiment, one of the connecting sleeves 15 is fixed on the housing 122, and the other connecting sleeve 15 is fixed on the tank body and is arranged close to the gas phase valve 3.

[0032] Driven by the power output member 121, the connecting rod 134 can move in the connecting sleeve 15. The setting of the connecting sleeve 15 can limit the moving direction of the connecting rod 134, making the connecting rod 134 move along the axial direction of the connecting sleeve 15 to prevent the connecting rod 134 from shifting in position during the movement and avoid the situation where the gas phase valve 3 cannot be opened or closed in a timely manner.

[0033] In this embodiment, the hardness of the guiding sleeve 14 is less than that of the connecting sleeve 15. Among them, the guiding sleeve 14 is made of plastic material, providing guidance for the movement of the wire rope 133 while conforming to the displacement change of the wire rope 133; the connecting sleeve 15 is made of metal material, thereby limiting the moving direction of the connecting rod 134.

[0034] In addition, in this embodiment, the power output member 121 is detachably mounted on the valve stem 21 of the loading and unloading valve 2. The loading and unloading valve 2 of this embodiment is provided with a handle 22 or a driver for driving the valve stem 21 of the loading and unloading valve 2 to rotate. After the power output member 121 is detachably mounted on the loading and unloading valve, when the handle 22 or the driver drives the valve stem 21 to rotate, the power output member 121 can be driven to move simultaneously to output power outward. In some other preferred embodiments, as Figure 3 shown, the power output member 121 and the valve stem 21 of the loading and unloading valve 2 are of an integral structure.

[0035] Refer to Figure 4 , in another preferred embodiment, the structure of the linkage control device 1 is substantially the same as that of the above embodiment, and its main difference lies in that: the power output member 121 includes a gear 1211 and a rack 1212 meshing with the gear 1211. Among them, the gear 1211 is fixed on the valve stem 21 of the loading and unloading valve 2 and can rotate with the rotation of the valve stem 21 of the loading and unloading valve 2. The rack 1212 is movably mounted on the loading and unloading valve 2, and the linkage member 132 is connected to the rack 1212.

[0036] When the valve stem 21 of the loading and unloading valve 2 rotates under the action of an external force, the gear 1211 can rotate with the rotation of the valve stem 21 of the loading and unloading valve 2. Under the meshing action of the gear 1211 and the rack 1212, the rotating gear 1211 can drive the rack 1212 to move. The moving rack 1212 can pull or push the linkage 132, so that the linkage 132 moves in the guide 131, so that the other end of the linkage 132 pulls or pushes the follower 111, so that the follower 111 drives the valve stem 31 of the gas phase valve 3 to rotate, and opens or closes the gas phase valve 3.

[0037] In this embodiment, the rack 1212 is movably installed in the housing 122. Limit members 16 are respectively provided on both sides in the length direction of the rack 1212 for limiting the moving direction of the rack 1212, so that the rack 1212 can only move along its own length direction.

[0038] This application also provides a tank body, the bottom of the tank body is provided with a loading and unloading valve 2, and the top of the tank body is provided with a gas phase valve 3. In this embodiment, the above-mentioned linkage control device 1 is also provided on the tank body.

[0039] Specifically, the follower 111 is fixed on the valve stem 31 of the gas phase valve 3 for driving the rotation of the valve stem 31 of the gas phase valve 3. The power output member 121 is arranged on the loading and unloading valve 2 and moves with the rotation of the valve stem 21 of the loading and unloading valve 2, and the guide member 131 is fixed relative to the tank body.

[0040] When the valve stem 21 of the loading and unloading valve 2 rotates under the action of an external force, the power output member 121 moves to drive the linkage 132 to move along the guide channel of the guide member 131, and the linkage 132 drives the follower 111 to rotate the valve stem 31 of the gas phase valve 3, so that the gas phase valve 3 is opened or closed, so as to realize the synchronous opening and closing of the loading and unloading valve 2 and the gas phase valve 3.

[0041] In the tank body of this embodiment, the loading and unloading valve 2 can be a butterfly valve, a ball valve or a plug valve. A handle 22 for driving the rotation of the valve stem is provided on the valve stem 21 of the loading and unloading valve 2, and the handle 22 can be a pneumatic, hydraulic or electric drive device.

[0042] In addition, this application also provides a tank container, which includes a frame and the above-mentioned tank body, and the tank body is supported by the frame.

[0043] For the tank container, the tank body and the linkage control device of the present application, when opening or closing the loading and unloading valve, the valve stem of the loading and unloading valve rotates to move the power output member, the power output member drives the linkage member to move in the guiding member, and the linkage member drives the follower member to rotate the valve stem of the gas phase valve, so as to realize the synchronous opening or closing of the gas phase valve. This setting can, on the one hand, prevent the operator from forgetting to open the gas phase valve when opening the loading and unloading valve, and prevent safety accidents caused by the instability of the tank body due to negative pressure; on the other hand, the operator can open and close the gas phase valve at the top of the tank body at the bottom of the tank body without climbing operations, reducing the safety risk of falling from a height; in addition, the linkage control device is easy to operate, has no hidden parts, and is relatively convenient for maintenance.

[0044] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be broadly construed within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
