DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The utility model provides a technical solution: an auxiliary device for accurately opening and controlling the opening of a manual valve, comprising: a valve body 1 and a rotating handle 6, both sides of the valve body 1 are connected with connectors 2, a hand wheel 3 is installed on the top of the valve body 1, the top of the hand wheel 3 is connected with a connecting block 4, the outer side of the connecting block 4 is sleeved with a sleeve 5, and the rotating handle 6 is installed on one side of the sleeve 5.

[0024] The outer side of the sleeve 5 is connected to the bracket 7 through a bearing, a fixing frame 19 is installed on one side of the bracket 7, a dial 8 is installed on the top of the fixing frame 19, an indicator mark 9 is installed on one side of the rotating handle 6, a supporting frame 10 is installed at the bottom of the fixing frame 19, a connecting ring 11 is installed at the bottom of the supporting frame 10, and the bracket 7 is installed on the inner wall of the fixing frame 19.

[0025] In specific implementation, the auxiliary device for accurately opening and controlling the opening of a manual valve can be used to control the valve by rotating the rotary handle 6. Since the bottom of the rotary handle 6 is sleeved on the outside of the connecting block 4 through the sleeve 5, the connecting block 4 is connected to the hand wheel 3. At the same time, the connecting block 4 is a rectangular structure. When the rotary handle 6 is rotated, the hand wheel 3 at the bottom is driven to rotate through the sleeve 5 and the connecting block 4, thereby playing a role in controlling the valve. At the same time, a bracket 7 is installed between the outside of the sleeve 5 and the fixed frame 19, and the bracket 7 is connected to the sleeve 5 through a bearing. When the rotary handle 6 drives the sleeve 5 to rotate, the bearing acts on the bracket 7. The frame 7 and the fixed frame 19 will not rotate with the sleeve 5, and the positions of the fixed frame 19 and the top dial 8 will remain unchanged. At the same time, when the rotating handle 6 rotates, it will drive the indicator mark 9 on one side to rotate. The user can judge the opening and closing degree of the valve by observing the position of the dial 8 corresponding to the indicator mark 9, thereby accurately controlling the valve and reducing human errors. The indicator mark 9 and the dial 8 can also reduce the operator's dependence on experience, and at the same time enhance repeatability. Different operators can achieve the same opening degree, and improve system stability, accurately control flow and pressure, and ensure efficient operation of the system.

[0026] See also Figure 2 , Figure 3 and Figure 6 It can be seen that when in use, the rotating handle 6 can be rotated as needed, and the indicator mark 9 can be rotated by rotating the rotating handle 6, so that the indicator mark 9 rotates to the position of the corresponding dial 8. By observing the value of the dial 8, the valve can be opened and closed accurately.

[0027] The bottom of the connecting ring 11 is connected to the first rotating ring 12 and the second rotating ring 13 through a rotating shaft, one side of the first rotating ring 12 is connected to a rotating block 14 through a rotating shaft, one side of the second rotating ring 13 is installed with a fixed block 15, the interior of the fixed block 15 is installed with a movable spring 16 through a groove, one end of the fixed block 15 is connected to a telescopic block 17 that passes through the fixed block 15, one side of the telescopic block 17 is installed with a clamping block 18, and the rotating block 14 forms a rotating structure with the first rotating ring 12 through the rotating shaft.

[0028] In specific implementation, the auxiliary device for precisely opening and controlling the opening of a manual valve can rotate the first rotating ring 12 and the second rotating ring 13 to both sides when the entire valve control device needs to be installed on the valve, and then the first rotating ring 12 and the second rotating ring 13 are sleeved between the connectors 2. At this time, the first rotating ring 12 and the second rotating ring 13 can be rotated so that the first rotating ring 12 and the second rotating ring 13 move closer to each other, and then the rotating block 14 on one side of the first rotating ring 12 is rotated by the rotating shaft so that the rotating block 14 rotates into the groove at the bottom of the fixed block 15, and the telescopic block 17 is pulled to one side, so that the telescopic block 17 makes the movable part inside the groove of the fixed block 15 The movable spring 16 is in a stretched state, and the movement of the telescopic block 17 drives the clamping block 18 to move. When the rotating block 14 rotates to the groove at the bottom of the fixed block 15, the telescopic block 17 is released, and the telescopic block 17 is reset by the movable spring 16, and drives the clamping block 18 to move to one side of the rotating block 14. The rotating block 14 can be limited in the groove at the bottom of the fixed block 15 through the clamping block 18, so that the first rotating ring 12 and the second rotating ring 13 are connected and fixed. The first rotating ring 12 and the second rotating ring 13 are sleeved on the outside of the connector 2, and the entire valve control device can be quickly installed on the valve body 1, which is convenient for users to quickly install and fix the valve control device.

[0029] Similarly, it is only necessary to pull the telescopic block 17 to one side again so that the locking block 18 does not limit the rotating block 14, and then the rotating block 14 can be rotated in the opposite direction so that the rotating block 14 rotates out of the groove at the bottom of the fixed block 15. Without the limitation of the rotating block 14, the first rotating ring 12 and the second rotating ring 13 can be separated, so that the valve control device can be quickly removed from the valve body 1.

[0030] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be seen that when in use, the first rotating ring 12 and the second rotating ring 13 can be connected to the two sides of the connecting head 2 according to the use requirements, and the first rotating ring 12 and the second rotating ring 13 can be fixed by the rotating block 14 and the clamping block 18, so as to facilitate the user to quickly install the valve control device on the valve.

[0031] To sum up: the auxiliary device for precisely opening and controlling the opening of a manual valve can install the valve control device on the valve, and insert the sleeve 5 into the connecting block 4 on the top of the handwheel 3, and then connect the pipelines on both sides of the connector 2 through the flange. At this time, turn the rotary handle 6, and with the cooperation of the sleeve 5 and the connecting block 4, the handwheel 3 will rotate, so that the opening and closing degree of the valve can be controlled. This is the use feature of the auxiliary device for precisely opening and controlling the opening of a manual valve.
