Sealing ring with inner screw thread

Abstract

The invention discloses a hard alloy accessory with an inner screw thread. The hard alloy accessory with the inner screw thread is characterized by comprising an accessory body which is made of an alloy material and is 1-10 mm in width, wherein the inner side surface of the accessory body is completely or partially provided with the screw thread. As an improvement, the accessory body is made of the alloy material, and the inner side surface of the accessory body is completely provided with the screw thread. The accessory body is made of a tungsten carbide material; and the inner side surface is completely or partially provided with the screw thread. The hard alloy accessory with the inner screw thread in such the reasonable design has a simple structure, can prevent rotation following phenomena and can guarantee normal work of machinery.

Description

technical field [0001] The invention belongs to the field of hard alloy fittings, and in particular relates to a hard alloy fitting with internal thread. Background technique [0002] Carbide accessories are required in general machines. Due to process requirements, alloy fittings are generally used in organic solvents, oils, and water with strong crystallinity and high-viscosity liquid slurries. Traditional alloy fittings are made of iron or aluminum alloys, but iron and aluminum have relatively low melting points and relatively strong metal activity. Therefore, the service life of alloy fittings produced by these two materials is relatively short. During the operation, friction will be generated in the middle contact of alloy fittings. Due to the limitation of traditional technology, the processed sealing ring cannot dissipate heat well, and the metal strength and heat dissipation of iron and aluminum alloy cannot meet the current requirements. There are technical requir...

AI Technical Summary

Problems solved by technology

Traditional alloy fittings are made of iron or aluminum alloys, but the melting points of iron and aluminum are relatively low and the metals are relatively active. Therefore, the service life of alloy fittings produced by these two materials is relatively short

During the operation, friction will be generated in the middle contact of alloy fittings. Due to the limitation of traditional technology, the processed sealing ring cannot dissipate heat well, and the metal strength and heat dissipation of iron and aluminum alloy cannot meet the current requirements. There are technical requirements, so it is easy to affect the machinery, affect the normal production order, and reduce the production efficiency of the enterprise

[0003] At the same time, most of the alloy fittings are now equipped with a stainless steel lining on the inner side. Such a structure is likely to cause the lining to fall off from the alloy fittings, causing the lining to rotate, resulting in unstable use effects and affecting the normal operation of the machine.
