Description

Technical Field

[0001] This utility model relates to the field of high-pressure hydraulic ball valve technology, and in particular to a high-pressure hydraulic ball valve locking device. Background Technology

[0002] High-pressure hydraulic ball valves are characterized by rapid opening and closing, convenient operation, low fluid resistance, good sealing performance, and easy maintenance. They are widely used in high-pressure pipelines in industries such as power, steel, hydraulics, gas, and natural gas. The valve core of a high-pressure hydraulic ball valve is connected to a fixed operating handle, which is used to open or close the valve. When the high-pressure hydraulic ball valve is closed, the valve stem is perpendicular to the pipeline direction. Due to the relatively long operating handle and the complex layout of surrounding pipelines, locking tools cannot achieve a stable and effective lock. Accidental opening of the valve can endanger the safety of personnel working on the affected area.

[0003] Currently, universal cable locks are used at the power station site. The universal cable is a rope structure that wraps around the high-pressure hydraulic ball valve. Because the rope material is elastic, it is difficult to restrict the rotation of the high-pressure hydraulic ball valve. When subjected to external force, the high-pressure hydraulic ball valve will still rotate, which poses a certain safety risk. Utility Model Content

[0004] In view of the technical problems existing in the background art, the purpose of this utility model is to provide a high-pressure hydraulic ball valve locking device, which facilitates the restriction of the rotation of the high-pressure hydraulic ball valve and prevents the high-pressure hydraulic ball valve from being opened accidentally when subjected to external force.

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

[0006] A high-pressure hydraulic ball valve locking device includes an upper rotating arm, a lower rotating arm, and a connecting seat. One end of the upper and lower rotating arms is inserted into the ground. A gear I is provided on one side of the upper rotating arm, and a gear ring is provided on one end of the lower rotating arm. The upper and lower rotating arms abut against each other, and the gear I meshes with the gear ring. A gear II is provided on one end of the connecting seat, and the gear II meshes with the gear ring. The upper rotating arm, lower rotating arm, and connecting seat are connected sequentially from top to bottom. The high-pressure hydraulic ball valve is detachably inserted into the connecting seat.

[0007] Preferably, the upper rotating arm is provided with a threaded hole I, the gear ring is provided with a partition plate, the partition plate is provided with a threaded hole II, the gear II is provided with a threaded hole III, and the threaded hole III passes through the gear III and the connecting seat.

[0008] Preferably, the connecting seat is provided with a slot, and the high-pressure hydraulic ball valve passes through the slot.

[0009] Preferably, the connecting seat is provided with a sliding groove, which is provided on both sides of the empty groove. A top block is provided inside the connecting seat, and the two sides of the top block are respectively connected to the sliding groove and can move along the direction of the sliding groove.

[0010] Preferably, the top block is provided with a threaded hole IV. When the upper rotating arm, the lower rotating arm, and the connecting seat are connected to each other, the threaded holes I, II, III, and IV are aligned.

[0011] Preferably, the locking device further includes a bolt assembly comprising a bolt and a nut, wherein the bolt is threadedly engaged with threaded holes I, II, III, and IV respectively, the bolt passes through threaded holes I, II, and III and finally extends into threaded hole IV, and the nut is connected at the upper end of the bolt.

[0012] Preferably, one side of the upper rotating stop arm is provided with a lug I and a lug II. A lock cap is connected to the lug II. The lock cap is hollow inside. Connecting ring I and connecting ring II are respectively provided at both ends of the lock cap. The connecting ring II and the lug II are rotatably connected. When the lower end of the lock cap contacts the upper rotating stop arm, the connecting ring I and the lug I are concentric.

[0013] Preferably, a lock is detachably connected to the connecting ring I and the lug I.

[0014] This utility model has the following advantages and beneficial effects:

[0015] In this utility model, the high-pressure hydraulic ball valve is inserted into the connecting seat, and gear I and gear II are respectively connected to the upper and lower ends of the gear ring. When the three are meshed, the whole device is stable, restricting the rotation of the high-pressure hydraulic ball valve. The bolt is inserted so that the top block and the high-pressure hydraulic ball valve abut against each other, further enhancing the stability of the whole device.

[0016] Second, in this utility model, the entire device adopts a detachable connection method, which not only has a simple structure, but also restricts the rotation of the high-pressure hydraulic ball valve when the various components are connected. When the high-pressure hydraulic ball valve needs to be used, the bolt can be unscrewed. The whole process is efficient and convenient, and at the same time, it greatly avoids the occurrence of safety accidents. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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 some embodiments of this utility model, but not all embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example

[0028] like Figure 1-7As shown, a high-pressure hydraulic ball valve locking device includes an upper rotating arm 2, a lower rotating arm 3, a connecting seat 4, and a bolt assembly. One end of the upper rotating arm 2 and the lower rotating arm 3 are respectively inserted into the ground and can be pulled out from the ground. In this utility model, the upper rotating arm 2 and the lower rotating arm 3 are inserted into the ground for easy installation and disassembly. The insertion only serves to change the height. A structure similar to a telescopic rod can also be used to achieve this effect. A gear I 21 is provided on one side of the upper rotating arm 2, and a toothed ring 31 is provided on one end of the lower rotating arm 3. The upper rotating arm 2 and the lower rotating arm 3 abut against each other, and the gear I 21 and the toothed ring 31 mesh. A gear II 5 is provided on one end of the connecting seat 4, and the gear II 5 meshes with the toothed ring 31. The upper rotating arm 2, the lower rotating arm 3, and the connecting seat 4 are connected sequentially from top to bottom. The operating handle of the high-pressure hydraulic ball valve 1 is detachably inserted into the connecting seat 4.

[0029] like Figure 1 , 4 As shown in Figures 5, 6, and 7, the connecting seat 4 is provided with a slot 41. The operating handle of the high-pressure hydraulic ball valve 1 passes through the slot 41. The shape of the slot 41 is larger than the operating handle of the high-pressure hydraulic ball valve 1, making it easy to insert the operating handle of the high-pressure hydraulic ball valve 1. At the same time, the operating handle in the slot 41 can only rotate within the width range of the slot 41, preventing the high-pressure hydraulic ball valve 1 from rotating at a large angle and preventing the high-pressure hydraulic ball valve 1 from being suddenly opened. The connecting seat 4 is provided with a sliding groove 42, which is located on both sides of the slot 41. A top block 6 is provided inside the connecting seat 4, with both sides of the top block 6 connected to the sliding groove 42 and able to move along the direction of the sliding groove 42. The high-pressure hydraulic ball valve 1 is located below the top block 6. When the top block 6 descends, it directly abuts against the high-pressure hydraulic ball valve 1, further restricting the rotation of the high-pressure hydraulic ball valve 1.

[0030] like Figure 1-7 As shown, the upper rotating stop arm 2 is provided with a threaded hole I22, the gear ring 31 is provided with a partition 32, the partition 32 is provided with a threaded hole II33, and the gear II5 is provided with a threaded hole III51, which passes through the gear II5 and the connecting seat 4. The top block 6 is provided with a threaded hole IV61. When the upper rotating stop arm 2, the lower rotating stop arm 3, and the connecting seat 4 are connected to each other, the threaded holes I22, II33, III51, and IV61 are aligned. When the gears I21, II5, and gear ring 31 are tightly connected, the gears I21 and II5 extend into the gear ring 31, with gear I21 at the upper end of the partition 32 and gear II5 at the lower end. Because the gears I21, II5, and gear ring 31 are meshed, when they are tightly connected, they are in a locked state and cannot rotate.

[0031] like Figure 6As shown, the bolt assembly includes a bolt 7 and a nut 71. The bolt 7 is threaded into threaded holes I 22, II 33, III 51, and IV 61 respectively. The bolt 7 passes through threaded holes I 22, II 33, and III 51 and finally extends into threaded hole IV 61. The nut 71 is connected at the upper end of the bolt 7. After the upper rotating arm 2, lower rotating arm 3, and connecting seat 4 are tightly connected, the bolt 7 is screwed in. The bottom of the bolt 7 is connected to the top block 6, causing the top block 6 to move continuously toward the high-pressure hydraulic ball valve 1 and to abut the operating handle of the high-pressure hydraulic ball valve 1, further restricting the rotation of the high-pressure hydraulic ball valve 1. At the same time, the bolt 7 can fix the upper rotating arm 2, lower rotating arm 3, and connecting seat 4. The nut 71 abuts against the upper rotating arm 2 to prevent the three from shaking and enhance the stability of the entire structure. When it is necessary to rotate the high-pressure hydraulic ball valve 1, simply unscrew the bolt 7 and remove the upper rotating arm 2, the lower rotating arm 3 and the connecting seat 4 in sequence.

[0032] like Figure 1 , 2 As shown in Figures 6 and 7, one side of the upper rotating arm 2 is provided with a hanging lug I 23 and a hanging lug II 24. A lock cap 8 is connected to the hanging lug II 24. The lock cap 8 is hollow inside. Connecting ring I 81 and connecting ring II 82 are respectively provided at both ends of the lock cap 8. The connecting ring II 82 and the hanging lug II 24 are rotatably connected. When the lower end of the lock cap 8 contacts the upper rotating arm 2, the connecting ring I 81 and the hanging lug I 23 are concentric. A lock 9 is detachably connected inside the connecting ring I 81 and the hanging lug I 23. The lock 9 is a traditional padlock, but it can also be other locking devices. The purpose is to fix the lock cap 8 and prevent the lock cap 8 from rotating. The lock cap 8 can cover the bolt assembly. The lock cap 8 can only be opened by opening the lock 9 to prevent workers from accidentally opening the high-pressure hydraulic ball valve 1.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
