Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a valve stem and the processing technology of the valve stem, which has the advantages of smooth surface and corrosion resistance, and solves the problem that the outside of the traditional valve stem is not smooth enough when it is processed, and it is not smooth when it is just made. Applicable, but after a period of use, the outside of the valve stem is oxidized, and it is difficult to see the difference with the naked eye, but the sealing of the valve stem itself is difficult to achieve, and users are quite annoyed by this

Abstract

The invention relates to the technical field of valve rod machining, and discloses a valve rod. The valve rod comprises a rod body, a thin rod is fixedly installed outside the rod body, four forging grooves are formed in the outside of the rod body and located on the right side of the thin rod, the right side of the rod body is fixedly provided with a clamping rod, and the outer part of the clamping rod is sleeved with a limiting ring. According to the valve rod and the machining process of the valve rod, a protection cushion ring sleeves a rod section in which the forging grooves are forged, so that the limiting ring is obtained, the roller section sleeved with the limiting ring is heated to 1000 DEG C, borax is put into a container, the heated roller section is inserted into the borax, the roller section is rotated, the rotating frequency is thirty revolutions per minute, and the roller section is taken out after twenty minutes; an anti-oxidation protective layer is generated outside the valve rod due to the fact that high temperature and the borax react, the valve rod cannot influence normal use due to corrosion when being used for a long time, the trouble of a user is avoided, and the use of the valve rod by the user is facilitated.

Description

technical field [0001] The invention relates to the technical field of valve stem processing, in particular to a valve stem and the processing technology of the valve stem. Background technique [0002] The valve stem is an important part of the valve. It is used for transmission. The upper part is connected to the actuator or the handle, and the lower part directly drives the valve core to move or rotate to realize the valve switch or adjustment function. At the same time, it is impacted and corroded by the medium, and it also has friction with the packing. Therefore, when selecting the material of the valve stem, it must be ensured that it has sufficient strength, good impact toughness, and anti-corrosion at the specified temperature. Scratch and corrosion resistance, the valve stem is a vulnerable part, and the mechanical processing performance and heat treatment performance of the material should also be paid attention to when selecting [0003] The outside of the tradi...
