Description

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to an operating rod for opening and closing a water meter valve. Background Art

[0002] In urban water supply systems and industrial fluid control systems, water meters, as an important device for measuring and monitoring water consumption, are widely used in multiple scenarios such as residences, commercial buildings, and industrial plants. In order to achieve effective control and maintenance of water flow, water meters are usually equipped with valve devices, allowing users or maintenance personnel to open or close the water flow when necessary, such as for maintenance, water meter replacement, or emergency water outages. However, traditional water meter valves are mostly located directly on the front of the water meter, and the operating position is often located underground, in narrow spaces, or in difficult-to-reach places. This brings great inconvenience to actual operation. It is not only time-consuming and labor-intensive, but may also cause accidental injuries or equipment damage due to improper operation. Therefore, the water meter valve must be opened and closed with an operating lever.

DETAILED DESCRIPTION

[0017] 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.

[0018] The following is combined with Figure 1-4 The specific implementation methods of the present utility model are further described in detail.

[0019] In this embodiment, by Figure 1-Figure 2 As shown, the utility model includes a valve stem 1, two L-shaped rods 2 are fixed to the bottom of the valve stem 1, a detachable digital torque meter 3 is threadedly connected to the top of the valve stem 1, a T-shaped operating rod 4 is threadedly connected to the top of the digital torque meter 3, a circular disk 5 is inserted into the T-shaped operating rod 4, a positioning assembly is provided on the valve stem 1, and an adjustment assembly for controlling the opening and closing of the positioning assembly is slidably provided on the circular disk 5;

[0020] The threaded connection directions between the digital torque gauge 3, the valve stem 1 and the T-shaped operating rod 4 are all the same;

[0021] By turning and unscrewing the T-shaped operating lever 4, the digital torque meter 3 can be removed;

[0022] When adjusting the water meter valve, first adjust the digital torque gauge 3 to the specified force value, then hold the T-shaped operating lever 4 to drive the valve stem 1 and the L-shaped rod 2 to insert into the valve. The two L-shaped rods 2 can clamp the valve. By turning the T-shaped operating lever 4, the valve can be driven to rotate and the valve can be opened and closed. The digital torque gauge 3 will display the force. When the force reaches the set value, an alarm will be issued to prevent damage to the valve caused by excessive force.

[0023] When debugging the regulating valve, after the valve rotation is completed, the regulating assembly controls the positioning assembly to lock the valve stem 1 to prevent the valve stem 1 from being driven by external influences during the debugging process, thereby avoiding affecting the debugging. During each debugging, the regulating assembly drives the positioning assembly to release the lock of the valve stem 1 to control the valve rotation;

[0024] The digital torque meter 3 may adopt a DNC digital torque meter 3.

[0025] In this embodiment, by Figure 1-Figure 2 As shown, a circular hole 6 is provided on the circular disk 5, and the lower end of the T-shaped operating rod 4 is circular, and the lower end of the T-shaped operating rod 4 has the same shape as the circular hole 6;

[0026] While the T-shaped rod 16 passes through the circular disk 5 , the circular disk 5 can also rotate around the central axis of the T-shaped rod 16 .

[0027] In this embodiment, by Figure 1 Figure 2 and Figure 4 As shown, the positioning assembly includes a sleeve block 15 that is sleeved and rotated on the lower part of the valve stem 1. A connecting plate 17 is fixed to the front of the sleeve block 15, a clamping block 18 is fixed to the lower part of the connecting plate 17, and a matching rod 19 is fixed to the upper part of the sleeve block 15. The upper end of the matching rod 19 is fixed to the bottom of the circular plate 5.

[0028] By rotating the circular disk 5, the matching rod 19, the sleeve block 15 and the clamping block 18 can be driven to rotate, thereby driving the positioning assembly to rotate by rotating the circular disk 5, so that the clamping block 18 is aligned with the pipe beside the valve, so that when the L-shaped rod 2 is inserted into the valve, the clamping block 18 is stuck on the pipe beside the valve. At this time, the positioning assembly is driven by the adjusting assembly to limit the valve stem 1. At this time, the valve stem 1 is limited by the pipe and the valve and cannot rotate.

[0029] In this embodiment, by Figure 2-Figure 3As shown, the adjustment assembly includes a cavity 7 opened in the sleeve block 15, an insert block 8 is slidably arranged in the cavity 7, a plurality of slots 9 are opened on the valve stem 1, a soft rope 10 is fixed to the front end of the insert block 8, and the soft rope 10 passes through the cavity 7, the matching rod 19 and the circular disk 5 in sequence. A limit block 11 is fixed to the top end of the soft rope 10, a spring 12 is provided in the cavity 7, the rear end of the spring 12 is fixed to the insert block 8, and the front end of the spring 12 is fixed to the sleeve block 15. Two limit posts 13 for limiting the limit block 11 are fixed on the circular disk 5;

[0030] By moving the limit block 11 toward the valve stem 1, the soft rope 10 can be pulled to move, thereby driving the plug block 8 away from the slot 9. When the plug block 8 is out of the slot 9, the valve stem 1 releases the limit, and the limit block 11 is moved so that the limit block 11 is located between the limit column 13 and the valve stem 1. Then, the limit block 11 is rotated to rotate the limit block 11. At this time, the limit block 11 presses against the two limit columns 13, and the spring 12 pushes the plug block 8 to drive the limit block 11 to move toward the limit column 13, so that the limit block 11 presses against the limit column 13, preventing the limit block 11 from automatically resetting, causing the plug block 8 to be inserted into the slot 9.

[0031] If the valve stem 1 needs to be limited, pull the limit block 11 again to rotate it, so that the limit block 11 passes through the two limit columns 13 and moves away from the valve stem 1. At this time, the spring 12 will push the insert block 8 into the slot 9 to limit the valve stem 1 again.

[0032] In this embodiment, by Figure 1-Figure 3 As shown, a sliding groove 14 is provided on the circular disk 5 . The sliding groove 14 is located just below the limiting block 11 , and the soft rope 10 passes through the sliding groove 14 .
