Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to a valve opening and closing device for a ship piping system. Background Art

[0002] In the fields of shipping, chemical industry, and municipal administration, pipelines need to be controlled and managed according to working conditions. Therefore, valves need to be installed on the pipelines. The valves include a valve disc for controlling rotation. By rotating the valve disc, the opening and closing states of the valves are controlled to control and manage the pipelines.

[0003] During ship construction, the internal piping layout is complex, with multiple pipelines crisscrossing each other. Valves may be located between multiple pipelines in a confined space, on pipelines that are too high, or on pipelines that are deep. When opening and closing such valves, workers are restricted by space and need to squeeze into small spaces, ascend, or climb enclosures to operate them. As a result, many valves in the pipelines inside the ship are difficult to open and close, resulting in incomplete or untimely opening and closing of valves, which can cause liquid leakage or insufficient supply, leading to major accidents. Furthermore, the safety of workers during construction cannot be guaranteed, resulting in both economic and personal losses.

[0004] In summary, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the existing technology. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0030] See also Figure 1 The present application provides a valve disc switch device for a ship piping system, including a valve clamping portion, a rotating motor 6 and a connecting rod 5.

[0031] The valve clamping portion includes two clamping members 11 and a connecting seat 10, and the two clamping members 11 are slidably connected to the connecting seat 10. The two clamping members 11 are arranged relative to each other and form a clamping area that can clamp the valve disc of the valve component. The valve clamping portion is used to be fixedly connected to the valve disc of the valve component through the clamping area. The output shaft of the rotating motor 6 is fixedly connected to the connecting seat 10, and the rotating motor 6 is used to control the forward or reverse rotation of the valve clamping portion. The length of the connecting rod 5 is telescopically adjustable. The bottom of the connecting rod 5 is fixedly connected to the rotating motor. The controller 2 is set on the top of the connecting rod 5, and the controller 2 is electrically connected to the rotating motor 6. The connecting rod 5 is used to extend the rotating motor 6 to the valve disc of the valve component.

[0032] This application provides a valve disc switch device for a ship's pipeline system. When the valve disc is located in a narrow space, too high, or too deep, it is inconvenient for workers to reach the valve disc to open and close it. A connecting rod 5 with adjustable length allows the valve clamping portion to be extended to the valve disc at different depths or heights. The valve disc is fixed by the clamping area, and the valve clamping portion is controlled by rotating the motor to control the rotation of the valve clamping portion, thereby controlling the opening and closing of the valve disc. This avoids pipeline failures caused by untimely opening and closing, and further ensures the safety of workers. This device has a wide range of applications and is easy to operate, making it suitable for widespread use.

[0033] In one embodiment, Figure 4As shown, a slide groove is provided on the bottom surface of the connecting seat 10, and the clamping member 11 is slidably connected to the connecting seat 10 through the slide groove. The size of the clamping area can be adjusted by adjusting the relative position of the two clamping members 11. The size of the clamping area can be adjusted according to the different sizes of valve components and valve discs, thereby expanding the range of use of the device and meeting the needs of valve components and valve discs of various specifications without having to replace the valve clamping part.

[0034] Specifically, the chute is arranged radially along the valve disc, with the two clamping members 11 positioned at two diametrical endpoints of the valve disc to prevent it from slipping off the disc during rotation. This device accommodates valve discs of various diameters, with the chute width being the maximum applicable diameter of the valve disc.

[0035] In one embodiment, the clamping member 11 includes a sliding end and a fixed end. A stopper is provided at the sliding end of the clamping member 11, through which the clamping member 11 slides within the chute. The stopper is used to prevent the clamping member 11 from sliding out of the chute. The fixed end of the clamping member 11 extends outside the chute and is fixedly connected to the valve disc of the valve member.

[0036] In one embodiment, an elastic member 7 is provided at each end of the chute along its length. One end of each elastic member 7 is fixedly connected to the end of the chute, and the other end of each elastic member 7 is connected to a clamping member 11. The two elastic members 7 cause the two clamping members 11 to move in the same direction under the pressure of the two elastic members 7, providing a preload force when the valve disc is fixedly clamped.

[0037] Specifically, the elastic member 7 is configured as a compression spring or a disc spring to ensure sufficient pre-tightening force when clamping the valve disc of the valve member.

[0038] In one embodiment, a clamping groove is provided on the clamping surface of clamping member 11. The clamping groove is located at the fixed end of clamping member 11. The cross-sectional shape of the clamping groove matches the outer shape of the valve disc, and the clamping groove is used to secure the outer side of the valve disc. The provision of the clamping groove increases the contact area between the valve disc and the clamping groove when they are in contact, increasing the friction between the two, and achieving a tighter connection between clamping member 11 and the valve disc, thereby preventing idling during rotation of the valve disc.

[0039] It should be noted that the top of the clamping groove is also used to limit the top of the valve disc. When the valve disc is rotated, downward pressure can be applied through the top to increase the friction between the clamping groove and the valve disc.

[0040] In one embodiment, a sliding surface is provided at the fixed end of the clamping member 11 , the sliding surface being connected to the clamping groove, and the sliding surface being used to guide the valve disc of the valve member to slide into the clamping groove.

[0041] It should be noted that a rounded corner is provided at the entrance of the sliding surface to prevent the valve disc from being damaged by collision when the sliding surface contacts the valve disc.

[0042] In one embodiment, a rubber layer is provided on the surface of the clamping groove to increase the friction between the valve clamping portion and the valve disc, thereby better transmitting the kinetic energy of the rotating motor to the valve disc.

[0043] In one embodiment, the connecting rod 5 is a three-section telescopic rod, including a first set of rods 51, a second set of rods 52 and a third set of rods. The two ends of the second set of rods 52 are respectively inserted into the first set of rods 51 and the third set of rods. The first set of rods 51 and the third set of rods are slidably connected along the ends of the second set of rods 52. Fasteners are sleeved on the outside of the first set of rods 51 and the third set of rods, and the fasteners are used to fix the length of the connecting rod 5.

[0044] like Figure 2 and Figure 3 As shown, the fastener includes a fastening screw 12, which is arranged perpendicular to the connecting rod 5. The end of the fastening screw 12 abuts against the outer side surface of the second set rod 52. After adjusting the length of the connecting rod 5, the sliding of the second set rod 52 is limited by tightening the fastening screw 12, so that the connecting rod 5 has a fixed length.

[0045] Specifically, the tops of the first and second rods 51 and 52 are slidably connected by a flat key, and the bottoms of the third and second rods 52 are slidably connected by a flat key. The provision of the flat key prevents the first and second rods 51 and the third and second rods 52 from rotating during rotation.

[0046] In one embodiment, the rotating motor 6 is arranged at the bottom of the connecting rod 5 and is sleeved inside the connecting rod 5. The output shaft of the rotating motor 6 extends outward and is fixedly connected to the top of the connecting seat 10 through the coupling 8. By arranging the rotating motor 6 at the bottom of the connecting rod 5, considering that the connecting rod 5 is too long and the torque is too large, the rotating motor 6 is arranged at the bottom and directly connected to the connecting seat 10 to prevent the distance between the rotating motor 6 and the connecting seat 10 from being too large and increasing the torque. Through the setting of the coupling 8, the output shaft and the connecting seat 10 rotate together during the transmission of motion and rotation, and do not disengage under normal circumstances, preventing the connected seat 10 from bearing excessive load. The coupling 8 also serves as an overload protection. A bearing 9 is coaxially sleeved on the outside of the coupling 8, and the outside of the bearing 9 is connected to the connecting rod 5.

[0047] In one embodiment, a power supply 1 is mounted on top of a connecting rod 5. The power supply 1 and controller 2 are electrically connected to a rotating motor 6 via a coiled spring cable 4. The controller 2 controls the forward and reverse rotation of the rotating motor 6, as well as its on / off function. Positioning the controller 2 on top of the connecting rod 5 facilitates operator operation. The coiled spring cable 4 allows for flexible length adjustment to accommodate varying lengths of the connecting rod 5.

[0048] In one embodiment, a handle 3 is provided on the top of the connecting rod 5 , and the controller 2 is provided on the handle 3 , so as to facilitate operation by a staff.

[0049] To use this device, first install the power supply 1. Slide and adjust the second set of rods 52 according to the valve position to adjust the length of the connecting rod 5. Tighten the fastening screw 12 to fix the length of the connecting rod 5. Align the valve clamp with the valve, grasp the handle 3, and apply downward pressure to slide the valve disc into the clamping groove. Use the controller to control the forward or reverse rotation of the rotary motor to control the clockwise or counterclockwise rotation of the valve. After the valve is opened and closed, turn off the rotary motor and pull the device upward to disengage the valve clamp from the valve disc.

[0050] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
