How does the top drive integrated valve achieve fluid control?

The operation of the top driven integrated valve is also more convenient. In traditional valves, the drive system and valve core are often separated and require operation through connecting rods or other mechanical devices. The top driven integrated valve can be opened and adjusted by simply moving the valve core up and down. Moreover, due to the tight fit between the valve cover and seat, the operating torque of the valve is also smaller, making it easier and more flexible to operate.

The top driven integrated valve is a device that controls the flow of medium manually or electrically, with its operating position located at the top of the valve. The advantage of this design lies in its ease of maintenance and safe operation. During the maintenance process, operators can directly enter the top of the valve to inspect and replace the internal devices without disassembling the valve. This greatly reduces maintenance time and workload, and improves maintenance efficiency.

How does the top drive integrated valve achieve fluid control?

Normal closure: In normal working condition, the top drive structure presses down the valve, causing it to fully contact the valve seat, thereby achieving a sealed closure of the valve and preventing fluid from passing through.

Open the valve: When the valve needs to be opened, the top drive structure lifts the valve stem, causing the valve to separate from the valve seat. Fluid can flow smoothly through valves.

Adjusting flow rate: By adjusting the rise or fall of the valve stem, the opening of the valve can be changed, thereby achieving control over fluid flow rate. The higher the valve stem, the greater the valve opening, and the fluid flow rate also increases accordingly. On the contrary, the lower the valve stem, the smaller the valve opening and the decrease in fluid flow.

Stop fluid flow: When it is necessary to stop fluid flow, the top drive structure presses down the valve stem, causing the valve to fully contact the valve seat and prevent fluid from passing through.

The working principle of the top driven integrated valve is to control the movement of the valve cover and disc through the valve stem, thereby achieving control over fluid flow. When the handle or motor on the valve stem rotates or moves, the valve stem drives the valve cover and disc to move together, thereby changing the opening degree of the valve. When the valve disc is completely closed, the valve seat comes into contact with the valve disc, forming a good seal and preventing fluid flow. When the valve disc is fully opened, the fluid can pass through the valve completely, achieving a maximum flow rate.

The sealing performance of the top driven integrated valve is also very good. Due to the integrated design of the valve core and valve seat, when the valve is closed, the valve core and valve seat are tightly fitted, forming a good sealing effect and effectively preventing fluid leakage. This characteristic makes the top driven integrated valve widely used in some applications that require high sealing, such as the petroleum, chemical, pharmaceutical and other industries.
