Description

Technical Field

[0001] The utility model relates to the field of valve regulating devices, in particular to a mechanical regulating device for a valve with ten thousand revolutions. Background Art

[0002] Multi-turn valves are widely used in the thermal power and chemical industries, especially in the thermal power industry. Due to the huge pressure of the gate valve, this type of valve involves a multi-stage speed change mechanism. From closing to full-load operation, it usually requires thousands to tens of thousands of valve rotations. Its implementation purpose is to open and close or regulate the energy efficiency of liquid and gas transportation to ensure production safety.

[0003] Generally, this type of valve is adjusted by manually holding an F wrench. Although the valve can be easily rotated, due to the excessive number of rotation turns, it is an extremely serious consumption of human power. The implementation purpose of this type of valve is especially to cut off the liquid and gas transportation when an uncontrollable danger occurs. In the relevant environment, the risk of operating this type of valve by staff cannot be controlled. Due to the slow closing of the valve by the staff, the risk is also difficult to estimate. For the above problems, there is currently no corresponding solution. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a mechanical regulating device for a valve with ten thousand revolutions that can drive with mechanical energy instead of manual regulation under the premise of not affecting the manual opening and closing operation of transmission, and improve the use safety in combination with specific working conditions.

[0005] The device includes a base, and the base is the assembly foundation of the device.

[0006] A power mechanism is slidably arranged on the base, and the power mechanism is connected to a driving wheel through a clutch mechanism.

[0007] The driving wheel is connected to the valve through a belt. The valve mentioned here refers to the handwheel of a valve that requires thousands to tens of thousands of revolutions to start and stop in the prior art.

[0008] The achieved effect is that when the clutch mechanism of the power mechanism is engaged, the driving wheel is driven, and the valve is rotated through belt transmission to replace the operation of manually closing and opening the valve; when the clutch mechanism is disengaged, the valve is opened and closed in the traditional manual way. That is, the valve cannot be manually driven due to the locking of the power mechanism.

[0009] The beneficial effects of the present utility model are as follows: The present utility model provides a new adjustment method for the ten-thousand-revolution valve in the prior art, that is, driving the valve to rotate by an external mechanical power, so as to achieve the effect of adjusting the valve. Based on the above, this device can save the physical strength of workers, improve the valve adjustment efficiency, especially in the face of special working conditions, it can replace manual adjustment by workers, realize the mechanical locking of the ten-thousand-revolution valve without personnel on duty, and thus improve production safety.
