Description

Technical Field

[0001] This utility model belongs to the field of valve fittings technology, specifically relating to a valve accessory. Background Technology

[0002] Valve accessories include handwheels, directional valves, and pressure regulating valves. In the design of some machines or equipment, space may be limited. Placing the handwheel at a higher position can prevent interference with other components, thus making efficient use of space. When the handwheel is located at a high position, workers typically need to stand on a ladder to adjust it. However, using a ladder for high-altitude work restricts the range of motion of the worker's hands and feet, leading to reduced work efficiency and posing a safety hazard as workers may fall.

[0003] Therefore, it is necessary to provide a valve accessory to address the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a valve accessory that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0006] A valve accessory includes a handwheel body with multiple sets of support shafts mounted inside. A handwheel operating mechanism is mounted on the handwheel body. The handwheel operating mechanism includes a transmission structure for controlling the rotation of the handwheel body and a mounting structure for mounting the transmission structure onto the handwheel body. The transmission structure includes an operating lever with a push rod hinged to it for pushing the support shafts. A limiting block for restricting the rotation direction of the push rod is mounted on the operating lever, and a reset assembly is mounted on the push rod.

[0007] In one or more embodiments of the present invention, the reset assembly includes an elastic band, one end of which is mounted on a push rod and the other end of which is mounted on a limiting block.

[0008] In one or more embodiments of this utility model, the outer wall of the push rod is fitted with a rubber layer that matches the support shaft.

[0009] In one or more embodiments of this utility model, an extension rod is installed at the bottom of the operating lever.

[0010] In one or more embodiments of this utility model, the outer wall of the extension rod is fitted with anti-slip particles that match the operating rod.

[0011] In one or more embodiments of this utility model, the mounting structure includes two sets of arc-shaped connectors symmetrically mounted on the handwheel body. The arc-shaped connectors are provided with connecting grooves that match the handwheel body. An adjustment component is installed between the two sets of arc-shaped connectors. An installation rod is installed on the adjustment component. The transmission structure is installed on the installation rod.

[0012] In one or more embodiments of the present invention, the adjusting assembly includes a first connecting rod, on which a second connecting rod is mounted, and the end of the second connecting rod away from the first connecting rod is mounted on an arc-shaped connector.

[0013] In one or more embodiments of this utility model, the first connecting rod has an internal thread, and the second connecting rod has an external thread that matches the internal thread.

[0014] In one or more embodiments of this utility model, a stop block is installed at the end of the mounting rod away from the handwheel body, and a mounting hole matching the stop block is provided on the extension rod.

[0015] In one or more embodiments of this utility model, the first connecting rod is an alloy internally threaded steel pipe.

[0016] Compared with the prior art, the valve accessory of this utility model eliminates the need for workers to stand on a ladder to adjust the handwheel when it is at a high position. This avoids, to some extent, the limited range of hand and foot movement of workers when using ladders for high-altitude operations, which could lead to reduced work efficiency and the possibility of falls while operating on ladders, thus posing certain safety hazards.

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figure 1 As shown, a valve accessory in one embodiment of this utility model includes a handwheel body 1, with multiple sets of support shafts 101 installed inside the handwheel body 1. A handwheel operating mechanism is installed on the handwheel body 1, which includes a transmission structure for controlling the rotation of the handwheel body 1 and an installation structure for mounting the transmission structure onto the handwheel body 1. When workers need to rotate the handwheel at a height, they first use a ladder to install the installation structure onto the handwheel body 1, and then return to the ground to drive the support shafts 101 through the transmission structure, thereby controlling the rotation of the handwheel body 1. This solves, to some extent, the problem of low work efficiency and safety when workers use ladders for high-altitude operations.

[0028] like Figures 1-3As shown, the transmission structure includes an operating lever 301, with a push rod 302 hinged to the operating lever 301 for pushing the support shaft 101. A limiting block 303 is installed on the operating lever 301 to restrict the rotation direction of the push rod 302, and a reset assembly is installed on the push rod 302. When the operator swings the operating lever 301, the push rod 302 is positioned to one side of the support shaft 101. Then, the operator pushes the operating lever 301 in the rotation direction of the handwheel body 1. With the support of the limiting block 303, the support shaft 101 is moved, thus completing the rotation of the handwheel body 1.

[0029] For example, such as Figure 1 The operator swings the operating lever 301, positioning the push rod 302 on the a' side (initial position). Then, the operating lever 301 is pushed in the direction the handwheel body 1 needs to rotate. Supported by the limit block 303, the push rod 302 pushes the support shaft 101, causing it to rotate, thus completing the rotation of the handwheel body 1. After a' rotates to position b', the operating lever 301 is swinged back to the (initial position). During this swing, influenced by the rotated a', the push rod 302 will experience an angle change. The reset assembly resets the push rod 302 to a position suitable for pushing the support shaft 101.

[0030] like Figures 2-3 As shown, the reset assembly can be a spring band 304 with one end mounted on the push rod 302 and the other end mounted on the limit block 303. During the process of the push rod 302 returning to its initial position, the angle will change counterclockwise due to the influence of the support shaft 101. At this time, the spring band 304 will extend. When the push rod 302 moves away from the support shaft 101 and is no longer restricted by the support shaft 101, the spring band 304 will shorten and pull the push rod 302 back, preparing for the next push of the support shaft 101.

[0031] like Figure 3 As shown, a rubber layer matching the support shaft 101 is installed on the outer wall of the push rod 302. The rubber layer can reduce the noise generated when the push rod 302 contacts the support shaft 101 during the push-pull and reset processes.

[0032] like Figure 1 As shown, an extension rod 305 is installed at the bottom of the operating lever 301. After the handwheel body 1 is turned, the operator can push the extension rod 305 back into the operating lever 301, minimizing the space occupied by the handwheel operating mechanism. The operating lever 301 can also be extended according to actual needs to match handwheel bodies 1 of different heights, thereby improving the practicality of the handwheel operating mechanism.

[0033] like Figure 1As shown, the outer wall of the extension rod 305 is equipped with anti-slip particles 306 that match the operating rod 301. The anti-slip particles 306 can effectively increase the friction between the operating rod 301 and the extension rod 305, so that the extension rod 305 can be stably stored in the operating rod 301.

[0034] like Figure 4 As shown, the mounting structure includes two sets of symmetrically mounted arc-shaped connectors 201 on the handwheel body 1. Each arc-shaped connector 201 has a connecting groove that matches the handwheel body 1. An adjustment assembly is installed between the two sets of arc-shaped connectors 201, and a mounting rod 202 is mounted on the adjustment assembly. A transmission structure is mounted on the mounting rod 202. The mounting structure is installed onto the handwheel body 1 that needs to be turned, so that the handwheel body 1 can be turned via the transmission structure.

[0035] Specifically, the arc-shaped connector 201 is installed onto the handwheel body 1 through the connection groove. The distance between the two sets of arc-shaped connectors 201 is adjusted by the adjustment component, so that the installation structure can turn the handwheel body 1 of different specifications, thereby improving the practicality of the handwheel operating mechanism.

[0036] like Figure 4 As shown, the adjustment assembly includes a first connecting rod 203, on which a second connecting rod 204 is mounted. The end of the second connecting rod 204 away from the first connecting rod 203 is mounted on an arc-shaped connector 201. After the operator installs one set of arc-shaped connectors 201 onto one side of the handwheel body 1, the other set of arc-shaped connectors 201 is pulled towards the other side of the handwheel body 1. Through the interference fit between the first connecting rod 203 and the second connecting rod 204, the distance between the two sets of arc-shaped connectors 201 is stabilized, thereby installing the arc-shaped connectors 201 onto the handwheel body 1.

[0037] Preferably, the first connecting rod 203 has an internal thread, and the second connecting rod 204 has an external thread that matches the internal thread. After the operator installs one set of arc-shaped connecting parts 201 onto one side of the handwheel body 1, by rotating the other set of arc-shaped connecting parts 201 and the first connecting rod 203, the other set of arc-shaped connecting parts 201 is moved to the other side of the handwheel body 1. That is, through the threaded connection between the first connecting rod 203 and the second connecting rod 204, the distance between the two sets of arc-shaped connecting parts 201 is stabilized, thereby connecting the arc-shaped connecting parts 201 to the handwheel body 1.

[0038] like Figure 5As shown, a stop 205 is installed at the end of the mounting rod 202 away from the handwheel body 1, and a mounting hole 3051 matching the stop 205 is provided on the extension rod 305. When the operator needs to rotate the handwheel body 1 in the reverse direction, after aligning the mounting hole 3051 with the stop 205, the transmission structure is removed, rotated 180 degrees and reinstalled, and then the support shaft 101 at position a” is moved to position b” by swinging the operating rod 301, thereby realizing the reverse rotation of the handwheel body 1.

[0039] like Figures 1-6 As shown, the first connecting rod 203 is an alloy internally threaded steel pipe. The alloy has high strength and toughness, which to some extent prevents the first connecting rod 203 from breaking during the rotation of the handwheel body 1 through the transmission mechanism.

[0040] During use, when the operator needs to rotate the handwheel body 1, the installation structure is installed onto the handwheel body 1 using a ladder, and then the transmission structure is connected to the installation rod 202. The handwheel body 1 is rotated by repeatedly swinging the operating rod 301. The operator does not need to stand on the ladder to rotate the handwheel body 1, which has a high safety factor and efficiency.

[0041] When the operator needs to rotate the handwheel body 1 in the reverse direction, the transmission structure is removed and installed in the reverse direction. The rotation of the handwheel body 1 can be achieved by repeatedly swinging the operating lever 301.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
