Problems solved by technology

[0002] At present, the valve body and packing gland of the slurry gate valve used in metallurgical mining, papermaking, cement, chemical and other industries adopt welded structure, the appearance is not beautiful, and the service life is short
There is no lubricating oil hole and protective device on the bearing part of the upper part of the screw. In places with poor working conditions such as industrial and mining enterprises, dust is easy to enter, which affects the use effect and service life; the valve is relatively large, and the installation and opening are cumbersome; It is easy to be scratched and scratched by different sundries, which affects the service life of the valve

Abstract

The invention relates to a tool form slurry gate valve which comprises a handwheel, a lead screw, filling pressure covers, a valve plate, a valve body, a sealing ring, a bearing and a positioning screw. The top end of the lead screw is provided with an oil cup. The lead screw is provided with oil holes at the parts cooperated with the bearing above and below a set square. The oil cup is communicated with the oil holds. The outside of the bearing is provided with a bearing protection hood. The upper part bearing protection hood and the handwheel is an integrated structure. The filling pressure cover at the upper end of the valve plate is provided with a sludge scraper. The valve body and the filling pressure covers is an integrated casting form. The sealing ring is embedded in a groove on the valve body. The bottom end of the valve plate is in a tool edge shape. The angle of the tool form is 40 degrees and made from stainless steel. The invention has the advantages of reasonable structure design, small size and long service life.

Description

technical field [0001] The invention relates to a knife-shaped pulp gate valve, which is widely used in metallurgical mines, papermaking, cement, chemical and other industries. Background technique [0002] At present, the valve bodies and packing glands of slurry gate valves used in metallurgical mining, papermaking, cement, chemical and other industries adopt welded structures, which have an unattractive appearance and short service life. There is no lubricating oil hole and protective device on the bearing part of the upper part of the screw. In places with poor working conditions such as industrial and mining enterprises, dust is easy to enter, which affects the use effect and service life; the valve is relatively large, and the installation and opening are cumbersome; In the middle, it is easy to be scratched and scratched by different sundries, which affects the service life of the valve. Contents of the invention [0003] The invention overcomes the deficiencies in...
