Abstract
The utility model relates to a valve in particular to a double slopes metal valve plate butterfly valve, including a bonnet 1, a valve body 2, a valve plate 3 and a shaft 4. The valve body 2 is provided with a sealing ring 6, and the bonnet 1 is installed at the valve body 2. The shaft 4 is provided with a sealing ring 8 with O-shape, and the sealing ring 8 is installed in a body hole of the valve body 2. The valve plate 3 is installed through a screw 7 in a valve plate groove of the shaft 4, and the valve plate groove and the valve plate 3 is installed with a sealing strip 5. The valve plate 3 is a double slopes metal valve plate. The left and right surface of the valve plate's external diameter are double slopes, and the upper and lower surface thereof is a cylinder shape. Because of the applying of the double slopes metal valve plate sealing, the utility model takes advantages of more flexibility compared with the present butterfly valve, flexible opening and close without leakage, the precise switch position, reliable performance and long life period.

Technical field
The utility model relates to a kind of valve, particularly a kind of double inclined plane valve metal film butterfly valve.
Background technique
Existing eccentric-butterfly-valve all includes bonnet, valve body, valve block and rotating shaft, seal ring is housed on the valve body, bonnet is installed on the valve body, " O " RunddichtringO is housed in the rotating shaft, it is installed in the body opening of valve body, and valve block is installed in the rotating shaft, and its valve block is two valve metal films of facing directly, on the sealing surface of valve metal film, rubber ring is housed, adopts rubber ring as valve opening, the Sealing of closing.Because valve metal film is immersed in-30～+ 120 ℃ of transformer oil for a long time, that rubber ring on it is easy to generate is aging, distortion, cracking and cause valve closing not tight, frictional force is big, open difficulty, when causing oil immersed transformer vacuum oil and operation and maintenance, can't open or close the transformer oil circuit, cause leakage or closing torque excessive, operation inconvenience.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes existing butterfly valve, and a kind of double inclined plane valve metal film butterfly valve is provided, with solve existing butterfly valve seal circle be easy to generate aging, distortion, cracking and cause valve closing tight, open problems such as inconvenience.
The technical solution of the utility model is: double inclined plane valve metal film butterfly valve comprises bonnet, valve body, valve block and rotating shaft, seal ring is housed on the valve body, bonnet is installed on the valve body, and " O " RunddichtringO is housed in the rotating shaft, and it is installed in the body opening of valve body, valve block is installed in the valve block groove in the rotating shaft, the valve block groove is located at the center of rotating shaft, between valve block groove and valve block Stamping Steel Ribbon is installed, and valve block is the double inclined plane valve metal film, face is parallel double inclined plane about its external diameter, and top and bottom are cylinder type.
The further technological scheme of the utility model is: the oblique angle about the valve block external diameter between face double inclined plane and the medial axis is the 2-8 degree.
The utility model further technological scheme is: the valve block groove is located at the lower end at rotating shaft center.
The utility model further technological scheme also can be: the valve block groove is located at the centre at rotating shaft center.
The further again technological scheme of the utility model is: valve body is provided with position limit pin.
The utility model has and opens flexibly, closes characteristics such as the back is non-leakage, the switching position accurate, reliable performance, long service life because the sealing of employing double inclined plane valve metal film is compared with existing reed valve.
