Technical Field

[0001] This application relates to the field of valve group control technology, and in particular to a fixing device for a handle-type hand valve. Background Technology

[0002] Hand-operated valves are valves that are controlled to open and close by a handle. Under complex working conditions, long-term use of hand-operated valves may cause vibration or external force to cause displacement, affecting operational stability and safety. Currently, fixing devices are used to fix the valve handle of hand-operated valves, but they lack stable and effective fixing structures. However, the fixing devices currently used have poor adaptability and are difficult to effectively fix hand-operated valves of different sizes or types. Moreover, the current fixing devices require rearrangement and repositioning after the valve handle needs to be released, resulting in low efficiency and high cost. Furthermore, the fixing process relies on manual experience to determine the degree of tightening, which increases the usage threshold and operational complexity. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0028] Hand-operated valves are widely used in industrial piping systems for controlling and regulating various media. However, under complex operating conditions, the valve handle may shift due to vibration or external forces, affecting operational stability and safety.

[0029] like Figure 1 , Figure 3 As shown, Figure 1 A top view of the fixing device provided in the embodiments of this application; Figure 3 A front view of the fixing device provided in an embodiment of this application.

[0030] A fixing device for a handle-type hand valve, the fixing device comprising a main body 100, a restraint member 200, and a locking member 300, wherein:

[0031] The main body 100 is used to fix it to the pipeline connected to the hand valve. The main body 100 is fixed to the pipeline connected to the hand valve, ensuring stability under various operating conditions and providing solid support for the entire fixing device. The main body 100 can adapt to pipelines of different specifications, ensuring a reliable connection with the pipeline, thereby firmly installing the fixing device on the pipeline and laying a solid foundation for subsequent valve handle fixing operations.

[0032] The constraint member 200 is fixedly connected to the main body 100, and the constraint member 200 is provided with a constraint groove 202 for accommodating the valve handle on the side away from the main body 100. An opening 203 is provided on one side of the constraint groove 202, and the valve handle can enter or exit the constraint groove 202 through the opening 203.

[0033] like Figure 1 As shown, the constraint member 200 is fixedly connected to the main body 100. The side of the constraint member 200 away from the main body 100 has a constraint groove 202 for accommodating the valve handle. The shape and size of the constraint groove 202 are designed to correspond to the valve handle, ensuring that the valve handle can reliably move into the constraint groove 202. An opening 203 is provided on one side of the constraint groove 202, through which the valve handle can enter or exit the constraint groove 202. This not only facilitates the installation and removal of the valve handle but also effectively constrains the valve handle after it enters the constraint groove 202, limiting its movement in a non-operating state. The fixed connection between the constraint member 200 and the main body 100 ensures the stability of the constraint groove 202, preventing the constraint member 200 from loosening due to vibration or external forces during long-term use, thus ensuring that the valve handle remains in a stable constrained state.

[0034] The locking member 300 is detachably connected to the constraint member 200, and the locking member 300 can block the opening 203 to restrict the valve handle from entering or leaving the constraint groove 202.

[0035] When the valve handle enters the constraint groove 202, the locking element 300 can be positioned on the opening 203, thereby restricting the valve handle from entering or leaving the constraint groove 202. This locking mechanism provides reliable protection for the valve handle; even under vibration or external force, the valve handle will not easily shift or disengage from the constraint groove 202. The detachable connection of the locking element 300 allows operators to quickly perform locking and unlocking operations without complicated tools or procedures. Furthermore, the connection strength between the locking element 300 and the constraint element 200 has undergone rigorous testing to ensure a stable and reliable locked state under various operating conditions.

[0036] like Figure 1 , Figure 3 As shown, in actual operation, when it is necessary to fix the valve handle, the operator first moves the valve handle into the constraint groove 202. At this time, the valve handle, restricted by the constraint groove 202, can only move along the axial direction of the constraint groove 202 and cannot move in other directions. Next, the operator installs the locking member 300 on the constraint member 200 and positions the locking member 300 at the opening 203. The connection between the locking member 300 and the constraint member 200 can be a threaded connection, a snap-fit ​​connection 401, or other reliable mechanical connection methods. After the locking member 300 is installed in place, the locking member 300 and the constraint member 200 form a structure that prevents the valve handle from coming out of the constraint groove 202. At this time, even if subjected to external vibration or impact, the valve handle can remain stable and will not shift or shake.

[0037] When the valve handle needs to be released, the operator simply removes the locking element 300 from the restraint element 200 and then moves the valve handle outside the restraint groove 202. Due to the arrangement of the opening 203 in the restraint groove 202, the valve handle can be smoothly moved out of the restraint groove 202 without any obstruction. The entire release process is equally simple and quick, requiring no complicated operating steps. This not only improves operational efficiency but also reduces the operator's workload, making the fixing and releasing of the valve handle easier and more convenient.

[0038] This fixing device is suitable for handle-type hand valves in various industrial piping systems, providing stable fixation for both high-temperature, high-pressure steam pipelines and low-temperature, low-pressure liquid transport pipelines. The robustness of the main body 100, the precise restraint of the constraint component 200, and the reliable protection of the locking component 300 together constitute an efficient and reliable fixing system. This fixing device significantly improves the operational stability of handle-type hand valves under complex operating conditions, effectively reducing safety risks caused by valve handle misalignment. Simultaneously, the ease of operation of this fixing device greatly improves work efficiency and reduces maintenance time and costs. Furthermore, its detachable design facilitates regular inspection and maintenance of the valve handle, ensuring long-term stable operation of the hand valve.

[0039] In an optional embodiment, the fixing device of this application is used to fix and maintain the valve handle of a handle-type hand valve. The fixing device includes a main body 100, a constraint member 200, and a locking member 300. The main body 100 is fixedly mounted on a pipe connected to the hand valve. The constraint member 200 is fixedly connected to the main body 100, and the side of the constraint member 200 away from the main body 100 is provided with a constraint groove 202 for accommodating the valve handle. An opening 203 is provided on one side of the constraint groove 202, through which the valve handle can enter or exit the constraint groove 202. The locking member 300 is detachably connected to the constraint member 200 and can block the opening 203 to restrict the valve handle from entering or exiting the constraint groove 202.

[0040] This fixing device boasts strong versatility and adaptability. The opening 203 of the constraint groove 202 allows valve handles of different sizes to enter or exit, accommodating various specifications of handle-type hand valves, greatly improving the versatility and adaptability of the fixing device. The main body 100 is fixed to the pipeline connected to the hand valve, ensuring the stability and reliability of the entire fixing device, effectively preventing the valve handle from shifting due to vibration or external force, and capable of withstanding long-term vibration and external force.

[0041] The locking element 300 is detachably connected to the restraint element 200. Operators can quickly lock and release the valve handle by simply removing and installing the locking element 300, eliminating the need for complex adjustments and positioning, thus greatly improving work efficiency. Simultaneously, when the locking element 300 is positioned on the opening 203, it allows for a direct visual assessment of whether the valve handle is locked, avoiding problems caused by relying on human experience to judge the tightness, lowering the barrier to entry and reducing operational complexity. The restraint groove 202 securely fixes the valve handle, while the reliable connection of the locking element 300 further restricts the movement of the valve handle. Even under vibration or external force, the valve handle is not easily displaced, thereby improving operational stability and safety.

[0042] like Figure 1 , Figure 3 As shown, in an optional embodiment, the constraint member 200 includes two spaced baffles 201, which are fixedly connected to the main body member 100.

[0043] The two baffles 201 are fixedly connected to the main body 100. This allows the constraint member 200 to form a stable spatial structure on the main body 100, providing reliable constraint for the valve handle. The distance between the two baffles 201 ensures that the valve handle can smoothly enter the constraint groove 202 while being sufficiently restricted to prevent movement during non-operation. The constraint member 200 not only effectively fixes the valve handle but also adapts to valve handle variations within a certain size range, improving the versatility and adaptability of the fixing device.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 2 This is a side view of the fixing device provided in an embodiment of this application. In an optional embodiment, the locking member 300 passes through the constraint member 200 and is threadedly connected to the constraint member 200. This provides a reliable fixing means for the locking member 300. When it is necessary to lock the valve handle, the operator only needs to screw the locking member 300 into the threaded hole of the constraint member 200 until the locking member 300 is tightly abutted at the opening 203 of the constraint groove 202. The self-locking performance of the threaded connection ensures that the locking member 300 will not easily loosen under vibration or external force, thereby maintaining the locked state of the valve handle for a long time. When it is necessary to release the valve handle, simply rotate the locking member 300 in the opposite direction to unscrew it from the constraint member 200. This connection method is simple to operate, requires no additional tools, improves work efficiency, and the strength and reliability of the threaded connection also provide a strong guarantee for the overall performance of the fixing device.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment, the fixing device further includes a positioning element 400, which is connected between the pipe and the main body 100. The positioning element 400 is sleeved on the pipe, and the main body 100 is rotatably connected to the positioning element 400, providing additional flexibility and adjustability to the fixing device.

[0046] During actual installation, the operator can first place the positioning piece 400 onto the pipeline, and then rotate the main body piece 100 according to the position and direction of the hand valve, so that the main body piece 100 and the valve handle of the hand valve are at a suitable angle. This rotatable connection method allows the fixing device to better adapt to hand valves in different spatial positions, especially in situations where the pipeline layout is more complex or space is limited. The operator can easily adjust the angle of the main body piece 100 to ensure that the constraint groove 202 can be accurately aligned with the valve handle, thereby achieving quick and effective fixing.

[0047] In an optional embodiment, the positioning element 400 is movably connected to the pipe, and the positioning element 400 is rotatable about the centerline of the pipe and / or movable along the centerline of the pipe.

[0048] This movable connection method further enhances the flexibility and adaptability of the fixed device. When the pipeline itself experiences vibration or displacement, the positioning element 400 can adjust its position accordingly with the pipeline's movement, thereby maintaining a stable connection between the fixed device and the hand valve. Furthermore, this movable connection allows operators to move the positioning element 400 to its optimal working position as needed during installation or adjustment of the fixed device. For example, when the pipeline is long, the operator can move the positioning element 400 along the pipeline centerline to quickly install the fixed device on hand valves at different locations, greatly improving work efficiency and reducing the difficulty of installation and adjustment.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment, the positioning member 400 is provided with a ratchet 501, and the main body 100 is movably provided with a pawl 502, which can engage or disengage with the ratchet 501.

[0050] This ratchet 501 and pawl 502 engagement mechanism provides precise angle adjustment and positioning for the fixing device. When the angle of the main body 100 needs to be adjusted, the operator can push the pawl 502 to disengage it from the ratchet 501, and then rotate the main body 100 to the desired position. After reaching the appropriate position, the pawl 502 is released, and under its own elasticity or with the help of a spring or other reset device, the pawl 502 re-engages with the ratchet 501, fixing the main body 100 in that position. This allows the operator to quickly and accurately adjust the angle of the main body 100 with minimal force, achieving precise constraint on the valve handle. Simultaneously, the engagement of the ratchet 501 and pawl 502 has a self-locking function, preventing the main body 100 from shifting angle under vibration or external force, ensuring that the fixing device always remains in the set position, thereby improving the stability and reliability of the hand valve operation.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment, the positioning element 400 includes a clip 401 for clamping onto the pipe. The clip 401 provides a simple and effective installation method for the fixing device. The shape and size of the clip 401 are adapted to the outer wall of the pipe, allowing it to clamp tightly onto the pipe without the need for additional bolts or welding. The clip 401 is typically made of a material with a certain degree of elasticity and strength, such as metal or high-strength plastic, to ensure it can firmly clamp the pipe without damaging the pipe surface. This simplifies the installation process of the fixing device, reduces installation difficulty, and is especially suitable for applications requiring frequent installation and disassembly, thus improving work efficiency.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment, a locking bolt 403 is provided between the two latches 401, and the locking bolt 403 can drive the two latches 401 to move closer to each other.

[0053] This locking mechanism further enhances the clamping force of the clips 401 on the pipe, ensuring that the positioning element 400 can be securely installed on the pipe under various working conditions. Once the clips 401 are clamped onto the pipe, the operator can tighten the locking bolt 403 to gradually bring the two clips 401 closer together, thereby increasing the pressure of the clips 401 on the pipe and achieving a more secure clamping effect. The tightening degree of the locking bolt 403 can be adjusted according to actual needs to accommodate pipes of different diameters and materials. Furthermore, this locking mechanism can compensate for the decrease in clamping force caused by wear of the clips 401 due to long-term use by increasing the tightening force of the locking bolt 403, extending the service life of the fixing device and ensuring its long-term stable and reliable operation.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment, the buckle 401 has an arc-shaped segment 402 in the middle that adapts to the outer wall of the pipe. This arc-shaped segment 402 allows the buckle 401 to better fit the outer wall of the pipe, increasing the clamping area and thus improving the uniform distribution of clamping force. The curvature of the arc-shaped segment 402 matches the outer diameter of the pipe, ensuring that the buckle 401 can tightly fit the pipe surface during clamping, reducing stress concentration points and lowering the risk of pipe damage caused by excessive local pressure. At the same time, the design of the arc-shaped segment 402 can also adapt to pipe diameter variations within a certain range. When the pipe diameter changes slightly or there are certain manufacturing tolerances, the arc-shaped segment 402 of the buckle 401 can still maintain good fit, ensuring the installation stability and reliability of the fixing device. This not only improves the adaptability of the fixing device to different types and specifications of pipes, but also enhances its stability under vibration or external force, preventing the positioning element 400 from loosening or shifting on the pipe.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment, the positioning member 400 is provided with a control buckle 503 connected to the pawl 502. The control buckle 503 drives the pawl 502 to rotate, so as to switch the pawl 502 to engage or disengage with the ratchet 501.

[0056] The control latch 503 provides operators with a convenient means of operation, making the engagement between the ratchet 501 and the pawl 502 more flexible and controllable. The control latch 503 is located outside the positioning component 400, and operators can operate it manually or with simple tools. When the angle of the main body 100 needs to be adjusted, the operator simply pulls or pushes the control latch 503. The control latch 503 drives the pawl 502 to rotate around its connection point, disengaging the pawl 502 from the ratchet 501. At this time, the main body 100 can rotate freely, and the operator can easily adjust it to the desired position. After adjustment, releasing the control latch 503 causes the pawl 502 to automatically return to its original position under the action of a spring or other reset device, re-engaging with the ratchet 501 and locking the main body 100 in the new position. This design not only simplifies the operation process but also improves the accuracy and reliability of operation, enabling the fixing device to better meet the requirements of different working conditions and providing strong support for the stable operation of the handle-type hand valve.
