Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to an adjustable valve connecting component and a valve manual operator. Background Art

[0002] After a valve is installed, there are various types of actuators that can operate its opening and closing, such as electric actuators, gas-hydraulic actuators, pneumatic actuators, electro-hydraulic actuators, and manual operators. Among them, manual operation via a manual operator is the most common application method for valves.

[0003] The operator operates the handheld operator by rotating an external handwheel, which in turn actuates the valve. In typical installations, there's ample clearance for the handwheel. However, in some unusual installations, the handwheel may be oriented differently from the default orientation, causing physical interference between the handwheel or its handle and other external components. This interference can prevent the handle from being installed smoothly, or even after installation, prevent adequate clearance for operation, resulting in improper operation of the device.

[0004] Currently, the common solution to these special situations is for technicians to visit the site to measure the specific location of the interference. Based on the measured data, they then redesign and manufacture a valve connection component of a specific length, or find a similar-sized component from inventory as a replacement. Each of these non-standard solutions requires additional time for on-site survey, design, and production, resulting in significant time delays and financial losses. Utility Model Content

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] See also Figure 1-Figure 7 As shown, the specific embodiments provided by the present invention are as follows:

[0046] like Figures 1 to 3 As shown, the adjustable valve connection component proposed in this embodiment mainly includes an upper connection member 1 and a lower connection member 2. These two components cooperate with each other to adjust the total length of the connection.

[0047] Specifically, the upper connector 1 can be divided into two functional sections: a first connection end 101 at one end and a first connection portion 102 at the other. The first connection end 101 is configured to removably connect to a corresponding port on a valve operator to transmit torque input via the handwheel. The first connection portion 102 is typically a flat, plate-like structure with multiple adjustment holes 3 defined along its length.

[0048] Correspondingly, the lower connecting member 2 has a similar structure, comprising a second connecting end 201 and a second connecting portion 202. The second connecting end 201 is used for detachable connection to the valve operating shaft, and its interface can be adapted to the shape of the valve operating shaft to ensure effective torque transmission. The second connecting portion 202 is also a flat plate-like structure, also having an adjustment hole 3 formed therein.

[0049] When installing or adjusting the length, the first connecting portion 102 of the upper connecting member 1 and the second connecting portion 202 of the lower connecting member 2 are placed against each other and stacked. By sliding the two connecting portions relative to each other along the length direction, the overall length of the connecting component can be changed. When adjusting to the desired length, one or more pairs of adjustment holes 3 on the first connecting portion 102 of the upper connecting member 1 are aligned with the adjustment holes 3 on the second connecting portion 202 of the lower connecting member 2.

[0050] After alignment is complete, fasteners 4, such as a bolt and nut combination, are sequentially passed through the aligned adjustment holes 3. Finally, all fasteners 4 are tightened, generating a clamping force that securely fastens the first connecting portion 102 and the second connecting portion 202 together. This creates a stable, rigid connection across the selected length for the entire adjustable valve connection, enabling reliable transmission of operating force.

[0051] Through the above structure, the connecting components of the present invention can be conveniently selected and fixed between multiple preset lengths, so as to flexibly adapt to different length requirements caused by limited installation space or non-standard installation, and effectively solve the installation interference problem caused by fixed connection length in the prior art.

[0052] In a preferred embodiment, to further enhance the convenience and accuracy of the adjustment process, the adjustable valve connection component further includes a positioning assembly 5. The positioning assembly 5 is disposed between the upper connection member 1 and the lower connection member 2. Its primary function is to provide an accurate position signal when the two connection members are stacked and move relative to each other.

[0053] In practice, when adjusting the length of the connecting component, the user must adjust the positions of the upper and lower connecting members 2 to align the different adjustment holes 3. The positioning assembly 5 added in this embodiment is intended to address this alignment issue. Once the user has adjusted the desired length, the positioning assembly 5 initially positions and secures the upper and lower connecting members 1 and 2, preventing misalignment during subsequent installation of the fasteners 4.

[0054] As a specific and preferred implementation of the positioning assembly 5, a protrusion is provided on the stacking surface of one connecting portion (e.g., the first connecting portion 102 of the upper connecting member 1). This protrusion can be integrally formed during the processing of the connecting portion, or it can be a separate component installed later. Correspondingly, a plurality of positioning holes are provided on the stacking surface of the other connecting portion (e.g., the second connecting portion 202 of the lower connecting member 2). The distribution of these positioning holes corresponds one-to-one with the various gear positions of the adjustment hole 3.

[0055] Whenever the length of the connecting part is adjusted to a preset gear position, that is, when the main adjustment holes 3 are about to be aligned, the protrusion will be embedded in one of the positioning holes. Under slight pressure, the protrusion will be stuck in the positioning hole, forming a separable snap-fit.

[0056] This snapping action produces a distinct, tangible click or "click" sound. This tactile feedback clearly informs the operator that the adjustment hole 3 is aligned and the fastener 4 can be installed. To continue adjusting to the next position, a slightly greater force is applied to disengage the protrusion from the positioning hole. This simple mechanical engagement greatly facilitates the length adjustment process.

[0057] like Figure 6 As shown, in a preferred embodiment, in order to further improve the stability and alignment accuracy of the connecting parts during the adjustment and fitting process, the present invention may further include a guide assembly 6. The guide assembly 6 is also arranged between the upper connecting member 1 and the lower connecting member 2.

[0058] It should be understood that the guiding assembly 6 solves different technical problems than the aforementioned positioning assembly 5. The positioning assembly 5 is intended to provide a point-to-point gear confirmation signal, while the guiding assembly 6 is intended to provide guidance throughout the entire bonding process, thereby preventing the two separate components from tilting, misalignment, or jamming when approaching each other.

[0059] In the absence of the guide assembly 6, the operator needs to rely on feel and experience to ensure that the upper connecting member 1 and the lower connecting member 2 remain straight and aligned when approaching. If there is an angular deviation, it may cause alignment failure and reduce installation efficiency.

[0060] The guide assembly 6 introduced in this embodiment functions to constrain the relative positions of the upper and lower connectors during their assembly, ensuring that one component can only approach the other along a predetermined, correct trajectory. This significantly reduces installation difficulty, avoids repeated attempts or component damage due to misalignment, and makes the entire assembly process smoother and more stable, providing a reliable foundation for subsequent precise positioning and locking.

[0061] As a specific implementation of the guide assembly 6, it can be composed of contour structures that cooperate with each other on the overlapping surfaces of the two connecting parts.

[0062] Specifically, a guide groove with a predetermined profile is machined or formed along the length of one connecting portion (e.g., the second connecting portion 202 of the lower connecting member 2). Correspondingly, a boss structure matching the profile and dimensions of the guide groove is machined or formed on the stacking surface of the other connecting portion (e.g., the first connecting portion 102 of the upper connecting member 1).

[0063] During the bonding operation, the operator simply aligns the connecting part with the boss structure with the connecting part with the guide groove. Once the edge of the boss structure enters the guide groove, the inner wall of the guide groove acts as a track, constraining and guiding the position of the boss structure. At this point, all free play between the two connecting parts is eliminated, and the bonding is carried out solely along the path defined by the groove and boss until the surfaces of the two connecting parts are in full contact.

[0064] To further optimize the performance of the guide assembly 6, this embodiment provides a preferred cross-sectional profile. Specifically, the cross section of the guide groove is V-shaped or trapezoidal, and correspondingly, the cross section of the boss structure also has a V-shaped or trapezoidal shape that fully matches it.

[0065] When the connecting part with the V-shaped boss approaches the V-shaped guide groove, even if there is a certain left-right deviation in the initial position, the boss's inclined surface will first contact one of the groove's inclined surfaces. Under the action of the fitting pressure, this inclined surface generates a component force that pushes the boss toward the center until the two inclined surfaces of the boss and the groove are completely fitted.

[0066] This process automatically corrects alignment deviations and guides the two connectors to the centerline, greatly improving assembly tolerance and convenience. Compared to traditional rectangular cross-section guide rails, this V-shaped or trapezoidal structure also effectively avoids corner jamming caused by inaccurate angles, making the fitting process smoother.

[0067] like Figure 4 As shown, in a preferred embodiment, the present invention may further include an elastic damping layer 7 .

[0068] The elastic damping layer 7 is a sheet-like or gasket-like structure made of an elastic material with specific hardness and damping properties, such as high-strength rubber, polyurethane, or other polymers. During assembly, the elastic damping layer 7 is sandwiched between the overlapping contact surfaces of the first connecting portion 102 of the upper connector 1 and the second connecting portion 202 of the lower connector 2. The elastic damping layer 7 also has through-holes, corresponding to the adjustment holes 3 in the connecting portions, for the fasteners 4 to pass through.

[0069] When fastener 4 is tightened, this elastic damping layer 7 is firmly compacted. This provides shock absorption and prevents loosening. Secondly, it increases the static friction between the contact surfaces. The coefficient of friction between the compacted elastic material and the metal surfaces on either side is much higher than that of direct metal-to-metal contact. This makes the connection less susceptible to slippage when subjected to high torque, thereby enhancing the reliability of torque transmission.

[0070] Finally, the elastic damping layer 7 also provides sealing and corrosion protection. It effectively isolates moisture and air between the two metal connections, preventing interfacial corrosion or electrochemical corrosion caused by long-term contact, thereby extending the service life of the entire connection component. This is particularly effective in applications in humid or corrosive environments.

[0071] In a preferred embodiment, the first connection end 101 of the upper connector 1 is no longer a fixed structure integrally formed with the first connecting portion 102, but rather a removable upper connector module. Similarly, the second connection end 201 of the lower connector 2 is also a removable lower connector module. These two connector modules are connected to the first connecting portion 102 and the second connecting portion 202, respectively, as the adjustable body, through a removable connection method. This connection method can include, for example, standardized threaded connections, flange bolt connections, or keyed connections.

[0072] In actual applications, different brands and models of valve manipulators or valve operating shafts have widely varying sizes and shapes of connection interfaces (such as round, square, with keyways, splines, etc.). In traditional integrated structures, a connection component can only adapt to one specific interface combination.

[0073] This embodiment can be transformed into a device consisting of multiple dedicated interfaces according to actual needs, which greatly reduces the costs of production, storage and use.

[0074] In a preferred embodiment, in a conventional smooth-surface connection, torque is primarily transmitted through friction between the two connecting parts and the shear strength of the fastener 4. This connection poses the risk of slippage or damage to the fastener 4 and adjustment hole 3 when subjected to large or impact torque.

[0075] like Figure 5 As shown, to address this issue, this embodiment features matching locking teeth 8 machined onto the stacking surfaces of the first connecting portion 102 and the second connecting portion 202. These locking teeth 8 typically extend perpendicular to the length of the connecting components, and their tooth profile (e.g., sawtooth, rectangular, or trapezoidal) ensures that the teeth on the upper and lower surfaces mesh with each other when the two connecting portions are aligned.

[0076] When the fastener 4 is tightened, the positive pressure generated causes the two rows of interlaced locking teeth 8 to mesh tightly together, forming a rigid positive locking structure similar to a gear.

[0077] With this structure, when torque is transmitted from one end to the other, the force is no longer borne by the shank of the bolt. Instead, it is broken down and transferred to the vertical flanks of countless robust locking teeth 8. Fastener 4 no longer bears destructive shear forces, but instead provides only the positive pressure required for engagement. Neither the fastener itself nor the adjustment hole 3 in the connection will be deformed or damaged by the transmitted torque, significantly improving the durability and reliability of the entire connection.

[0078] like Figure 7 As shown, this embodiment also provides a valve hand operator 9:

[0079] At least includes the adjustable valve connecting component as described in any one of the above embodiments.

[0080] The valve hand operator 9 has all the above-mentioned beneficial effects, which will not be described in detail here.

[0081] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
