Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve operation technology, and in particular to a valve extension device. Background Technology
[0002] Ship piping is complex, with numerous systems distributed throughout the entire vessel. These pipelines contain various valves and accessories, essential components of the marine industrial piping system. Valves are crucial control components in fluid transport pipelines, performing functions such as shut-off, pressure regulation, pressure stabilization, and switching. Particularly in the engine room, valves of diverse specifications and types control the flow of fuel oil, water, air, steam, fresh water, and seawater. Their opening and closing operations are frequent, often requiring switching based on specific functions to ensure normal system operation. Due to the unique and complex nature of ships, many valves are located near oil and water-sealed compartments. Their size and location are influenced by the ship's space or platform height, potentially leading to operational inconveniences due to their placement. For example, in larger ships with significant height differences between decks, valves on the upper deck may be too high above the lower deck, making direct opening or closing impossible.
[0003] The above situation will make the daily maintenance and use of valves time-consuming and inconvenient. In emergency situations, such untimely operation can easily lead to problems in the corresponding pipelines, thereby affecting the operation and safety of the entire system and the normal navigation of the ship.

Detailed Implementation
[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0030] like Figures 1 to 6 As shown, this utility model provides a valve extension device, including: a fixed bracket 1, a support rod 2, an extension rod 3, a valve fork 4, and an operating handwheel 7.
[0031] The fixed bracket 1 is used to fix the device to the structural wall panel, and the fixed bracket 1 serves as the fixed support point for the entire valve extension device.
[0032] One end of the support rod 2 is fixedly connected to the fixed bracket 1, and the extension rod 3 is rotatably connected to the other end of the support rod 2, and the rotation axis of the extension rod 3 coincides with the axis of the extension rod 3; the axis of the support rod 2 is perpendicular to the axis of the extension rod 3, and the support rod 2 does not restrict the rotation of the extension rod 3 along its axial direction.
[0033] The valve fork 4 is installed at the end of the extension rod 3 away from the support rod 2, and the valve fork 4 is used to keep it relatively fixed to the valve 8.
[0034] The operating handwheel 7 is fixedly installed at the end of the extension rod 3 away from the valve fork 4. The connecting end of the operating handwheel 7 is fixedly connected to the extension rod 3. When the operator rotates the operating handwheel 7, the operating handwheel 7 can drive the extension rod 3 to rotate, thereby driving the valve fork 4 to rotate synchronously, and thus allowing the valve fork 4 to drive the valve 8 to rotate.
[0035] The length of the extension rod 3 is not further limited here. The length of the extension rod 3 is such that the fixed bracket 1 is fixed in a position where it is convenient for personnel to rotate and operate the extension rod 3.
[0036] Based on this, the fixed bracket 1 is fixedly installed on the structural wall panel as the fixed fulcrum of the entire valve extension device. One end of the support rod 2 is fixedly connected to the fixed bracket 1, and the other end of the support rod 2 is rotatably connected to the extension rod 3. The valve fork 4 is installed on the end of the extension rod 3 away from the support rod 2, and the valve fork 4 is relatively fixed to the valve 8. This allows personnel to rotate the valve 8 by turning the operating handwheel 7 from a position far away from the valve 8, thereby solving the problem of difficult operation caused by the position restriction of the valve 8 in the prior art.
[0037] Furthermore, such as Figures 1 to 6 As shown, the fixed bracket 1 includes a pad 101 and an angle steel 102, wherein the pad 101 is a rectangular steel plate.
[0038] One end face of the pad 101 is fixedly connected to one end of the support rod 2, and the other end face of the pad 101 is fixedly connected to the angle steel 102, and the two end faces are the two end faces with the largest area of the pad 101.
[0039] The angle steel 102 is fixed to the structural wall panel by welding, thereby completing the fixation of the fixed bracket 1.
[0040] Furthermore, such as Figures 1 to 6 As shown, the pad 101 and the angle steel 102 are connected by bolts. The pad 101 and the angle steel 102 have threaded holes of the same specifications. The threaded holes of the pad 101 are located at the four right-angle positions of the pad 101. After the angle steel 102 contacts the corresponding end face of the pad 101, the position of the threaded hole of the angle steel 102 matches the position of the threaded hole of the pad 101. The pad 101 and the angle steel 102 are connected by bolts through the provided threaded holes, thereby simplifying the installation process of the fixed bracket 1.
[0041] Furthermore, such as Figures 1 to 6 As shown, the support rod 2 includes a rotating part 201 and a connecting part 202 that are fixedly connected.
[0042] The rotating part 201 is rotatably sleeved on the outer periphery of the extension rod 3. The rotating part 201 is a sleeve, and the inner wall of the sleeve is in contact with the outer wall of the extension rod 3. The sleeve is coaxial with the extension rod 3. The sleeve is provided to ensure the normal rotation of the extension rod 3 while restricting the displacement of the extension rod 3 in other directions, thereby completing the fixation of the extension rod 3 while ensuring the function of the extension rod 3.
[0043] The connecting part 202 is fixedly connected to the pad 101. The connecting part 202 is a round steel bar, and the round steel bar is welded to the center of the pad 101.
[0044] Furthermore, such as Figures 1 to 6 As shown, the valve fork 4 includes a mounting crossbar 401 perpendicularly connected to the extension rod 3 and a limiting vertical bar 402 perpendicularly connected to the mounting crossbar 401. The mounting crossbar 401 is installed at the end of the extension rod 3 away from the support rod 2. At this time, there are two limiting vertical bars 402, and the two limiting vertical bars 402 are respectively located at both ends of the mounting crossbar 401.
[0045] In use, the limiting vertical rod 402 is inserted into the gap of the valve handwheel or into the handwheel pad that is built into the valve handwheel. When the valve fork 4 rotates with the extension rod 3, the side wall of the limiting vertical rod 402 abuts against the valve handwheel and drives the valve handwheel to rotate, thereby solving the rotation problem of the valve 8.
[0046] Furthermore, such as Figures 1 to 6 As shown, the valve extension device also includes a telescopic rod 5. The valve fork 4 is connected to the extension rod 3 through the telescopic rod 5. The fixed end of the telescopic rod 5 is away from the valve fork 4 and located inside the extension rod 3. The telescopic end of the telescopic rod 5 extends out of the extension rod 3 and is close to the valve fork 4.
[0047] Furthermore, such as Figures 1 to 6 As shown, the valve extension device also includes a universal joint 6. The telescopic rod 5 and the valve fork 4 are connected by the universal joint 6. The two fixed parts of the universal joint 6 are fixedly connected to the valve fork 4 and the telescopic rod 5, respectively. The rotating part of the universal joint 6 for adjusting the angle is limited by a pin. The universal joint 6 enables the valve fork 4 and the telescopic rod 5 to rotate at a certain angle.
[0048] Due to space limitations inside the ship's cabins, it is not possible to directly install the extension rod 3 in the same space in many cabins with a lot of large equipment. Therefore, when necessary, one end of the extension rod 3 used for personnel operation and rotation needs to be set in other cabins. However, due to the different positions of the cabins, the angle between the extension rod 3 and the valve 8 cannot be fixed at one angle.
[0049] Figure 5 In the case shown, the axes of the extension rod 3, the valve fork 4, and the valve 8 coincide, and the valve fork 4 can be directly installed on the valve 8 without adjusting the angle between the extension rod 3 and the valve fork 4.
[0050] Figure 6 As shown, the axes of the extension rod 3, the valve fork 4, and the valve 8 do not coincide. The valve fork 4 needs to be adjusted before it can be installed on the valve 8 to rotate. The universal joint 6 ensures that the extension rod 3 can extend from other compartments and directly connect to the valve 8.
[0051] Furthermore, such as Figures 1 to 6 As shown, the extension rod 3 is a seamless steel pipe. Both ends of the seamless steel pipe used for the extension rod 3 are internally threaded to facilitate the installation of the telescopic rod 5 and the operating handwheel 7.
[0052] Furthermore, such as Figures 1 to 6 As shown, the fixed bracket 1, support rod 2, valve fork 4 and operating handwheel 7 are all steel structural components, and the corresponding steel structural components are all treated with hot-dip galvanizing or epoxy paint coating for corrosion protection.
[0053] In summary, this utility model provides a valve extension device. The valve extension device uses the fixed bracket 1 and the support rod 2 to install the extension rod 3 for manual operation on the structural wall panel. The valve fork 4 for driving the valve 8 to rotate is installed at the end of the extension rod 3 away from the support rod 2, so that the operator can drive the valve 8 to rotate by rotating the extension rod 3 from a position far away from the valve 8. This solves the problem of difficult operation caused by the position restriction of the valve 8 in the prior art.
[0054] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
