进口波纹管密封蝶阀哪家品牌好

进口波纹管密封蝶阀Product Description:

The utility model comprises a valve body, a valve plate, an end cover, a valve rod, a bellows, an upper valve cover and a rotating shaft, the upper valve cover and the end cover are connected with the valve body, the central axes of the upper valve cover and the end cover are perpendicular to each other, the valve plate is covered at the end cover, a bellows is arranged in the upper valve cover, and the rotating shaft is fixed in the valve body. The valve plate rotates and opens with the rotating shaft as the shaft, and also includes a swing arm, a rotating shaft and a connecting rod. The other end of the valve rod is hinged with one end of the connecting rod, and the other end of the connecting rod is hinged with the, The swing arm is fixedly connected with the valve plate, and the end of the bellows is connected to the valve rod. The advantages are: the overall structure design is reasonable and easy to implement. The valve rod can drive the connecting rod to move through the up and down movement, and the connecting rod drives the valve plate to rotate, so as to realize the opening and closing of the valve plate. In this process, the bellows only performs telescopic movement and will not rotate.

进口波纹管密封蝶阀characteristic:

The bellows sealed butterfly valve comprises a valve body, a valve plate, an end cover, a valve rod, a bellows, an upper valve cover and a rotating shaft, the upper valve cover and the end cover are connected with the valve body, the central axes of the upper valve cover and the end cover are perpendicular to each other, the valve plate is covered at the end cover, a bellows is arranged in the upper valve cover, the rotating shaft is fixed in the valve body, the valve plate rotates and opens with the rotating shaft as the shaft, and also includes a swing arm, a rotating shaft and a connecting rod, and the other end of the valve rod is hinged with one end of the connecting rod, The other end of the connecting rod is hinged with the swing arm, the swing arm is fixedly connected with the valve plate, and the end of the bellows is connected to the valve rod.

进口波纹管密封蝶阀Principle:

The valve rod can drive the connecting rod to move by moving up and down, and the connecting rod drives the valve plate to rotate, so as to realize the opening and closing of the valve plate. In this process, the bellows only makes telescopic movement without rotation. Through this structure, the rotary movement of the valve plate is changed into the up and down movement of the valve rod, so as to ensure that the bellows only expands and contracts, ensure the sealing of the bellows and ensure the normal service performance of the bellows. The utility model solves the problem that the rotary valve cannot use the bellows for external leakage sealing, and expands the application range of the bellows, so that it can be used in the angle stroke valve.
