Problems solved by technology

[0003] At present, the knife gate valve used in production practice controls the lifting of the gate plate through the rotation of the hand wheel, which cannot realize automatic control. Because the gate plate causes loose parts during the extrusion process, the sealing effect will not be good after a period of use.
If the gate is kept open for a long time, impurities in the liquid medium may remain inside the parts, resulting in poor sealing and equipment wear, etc.

Abstract

The invention belongs to the technical field of valves, and particularly relates to a self-flushing super-wear-resistant slurry knife gate valve. The invention provides a self-flushing super-wear-resisting slurry knife gate valve. The self-flushing super-wear-resisting slurry knife gate valve comprises a driving part, a supporting part, a transmission part, a connecting part, an executing part, a first sealing part, a second sealing part, a valve deck, a first valve body and a second valve body. The driving part is movably connected with the transmission part, the transmission part is fixedly connected with the executing part through the connecting part, the executing part sequentially penetrates through the valve deck, the first sealing part and the second sealing part, and the first valve body and the second valve body are symmetrically arranged on the two sides of the executing part. The first valve body and the second valve body are fixedly connected with the valve deck at the same time, and the supporting part is connected with the driving part and the valve deck. Turbulent flow is formed in the valve, the groove in the valve is flushed, impurity accumulation is avoided, friction of parts is reduced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a self-flushing super wear-resistant slurry knife gate valve. Background technique [0002] Knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, smooth passage, small flow resistance, light weight, easy installation and disassembly, etc., and is widely used in mining, steel, wastewater purification , papermaking and power station ash removal and other fields. [0003] At present, the knife gate valve used in production practice controls the lifting of the gate plate through the rotation of the hand wheel, which cannot realize automatic control. Because the gate plate causes loose parts during the extrusion process, the sealing effect will not be good after a period of use. . If the gate remains open for a long time, the impurities in the liquid medium may remain inside the p...
