Abstract
The utility model relates to a back flushing filter with automatic pressure regulation. A main body is a high-pressure bottle which is composed of an end socket, a flange and a cylinder body. The back flushing filter is suitable to filtering requirements of different media, such as water, oil and gas to suspended solids. The application area is very wide, the structure of the device is compact, a drive chain is succinct, and filter elements can be washed without abrading, so the service life is extra long. The unique vane design and the fluid dynamics principle are applied, so the back flushing pressure force can be regulated automatically. Therefore, the back flushing filter is suitable for situations of lacking back flushing pressure force, and a common back flushing filter can not be used. The blank of the back flushing filter with automatic pressure regulation is filled. The effect of experiment is good. The product is divided into two modes of an electric mode and a manual mode, and the electric mode can also be divided into a time setting mode and a pressure difference setting mode.
