High wear-resistant alumina zirconium copper gold iron tailings pulp valve

Abstract

The invention discloses a high wear-resistant alumina zirconium copper gold iron tailings pulp valve, and relates to the field of mining valve bodies. The high wear-resistant alumina zirconium coppergold iron tailings pulp valve comprises a valve lining body, two groups of valve bodies and a valve plate body, wherein the valve plate body slides inside the valve lining body; a packing body and a gland body are connected to the outer side of the valve lining body in a sleeving mode, the gland body is fixedly connected to the upper surfaces of the two groups of the valve bodies by bolts, and a lifting mechanism is arranged at the top of the valve plate body. The high wear-resistant alumina zirconium copper gold iron tailings pulp valve is a full-diameter cut-off valve, when the valve is opened, the valve plate body is completely lifted to the interior of a valve cavity, the valve plate body is not in direct frontal contact with a medium, and wear to the valve plate body is avoided; a lining is integrally cast with polyurethane elastomer, so that ultra-long wear resistant life is provided; and the valve lining body and the valve plate body are easy to replace, and the valve can be replaced in time after being used and worn for a long time to ensure the normal use of the valve.

Description

technical field [0001] The invention relates to the technical field of mining valve bodies, in particular to a high wear-resistant alumina zirconium copper gold iron tailings slurry valve. Background technique [0002] In the fields of mining, coal slime separation, papermaking slag discharge, electric power, flue gas desulfurization, fuel transportation, sand-water mixture transportation and sewage treatment, shut-off valves are often used between pipelines to facilitate on-off control when transporting materials . [0003] The existing valve shut-off valve is generally unable to completely lift the valve plate into the valve cavity, so the valve plate may be in direct frontal contact with the medium, which causes the valve plate to be washed by the medium and cause wear, which will easily lead to the valve plate and the valve plate over time. If the lining is damaged, the overall service life of the traditional cut-off valve lining is not long, and the traditional cut-off...

AI Technical Summary

Problems solved by technology

[0003] Existing valve cut-off valves generally cannot fully lift the valve plate to the inside of the valve cavity, so the valve plate may directly contact the medium directly, causing the valve plate to be washed by the medium and cause wear, which will easily lead to valve plate and valve over time. The lining is damaged, and the overall life of the traditional shut-off valve lining is not long. When the valve plate and valve lining of the traditional shut-off valve are damaged, the shut-off valve needs to be replaced. The operation is cumbersome, time-consuming and laborious, and cannot ensure the normal use of the valve in time. Aiming at the deficiencies of the prior art, the present invention discloses a high wear-resistant aluminum oxide zirconium copper-gold-iron tailings slurry valve to solve the above problems
