Abstract

The invention relates to the technical field of valves, in particular to a novel double-seal wear-resistant valve. The novel double-seal wear-resistant valve is characterized by comprising an electric device, an oil nozzle, a valve rod nut, a plane bearing, a cylinder, a filler pressing plate, flexible graphite, an upper seal, a screw, a composite gasket, a valve rod, a hard seal, a gate, a joint, a valve body and a bleed hole. The novel double-seal wear-resistant valve is provided with double seals, the flexible graphite is arranged at the joint of the valve rod and the valve body, and the hard seal is arranged at the gate, so that the valve has high corrosion resistance, high abrasion resistance and high wear resistance.

Description

Technical field [0001] The invention relates to the technical field of valves, in particular to a novel double-sealed wear-resistant valve. technical background [0002] Traditional gate valves often have fouling phenomenon, the valve is worn seriously, which affects the sealing performance of the gate, and the slag cannot be discharged in the valve, which greatly affects the service life of the valve. Summary of the invention [0003] In order to solve the above shortcomings, a new type of double-sealed wear-resistant valve with good sealing performance, corrosion resistance and long life is provided. The new type of double-sealed wear-resistant valve is characterized in that it includes: an electric device 1. an oil nozzle 2. Stem nut 3, plane bearing 4, cylinder 5, packing pressure plate 6, flexible graphite 7, upper seal 8, screw 9, composite gasket 10, valve stem 11, hard seal 12, gate 13, joint 14, valve Body 15, slag discharge port 16, the new type of double-sealed wear-re...
