Abstract
The utility model relates to a seal assembly specifically says to relate to a wear -resisting anti -corrosion governing valve seal assembly. A wear -resisting anti -corrosion governing valve seal assembly, includes case and disk seat, sets up the sclerosis layer at the surface of case and disk seat. The utility model provides an effect is: laser cladding technology is adopted in the preparation on disk seat, case case hardening layer for the sclerosis layer is metallurgical bonding with the base member, has increased bonding strength and hardness, the superhard layer of vapour deposition preparation has promoted disk seat, stand wear and tear, the resistant erosion of valve rod, gasproof and has lost the performance.
Description
Technical field
Originally it is new to be related to a kind of black box, in particular relate to a kind of wear-and corrosion-resistant regulating valve black box.
Background technology
In the industries such as petrochemical industry, Coal Chemical Industry, polysilicon, electric power, big adjustable valve, wherein flash distillation, gas are widely present
Under the bad working environments such as erosion, erosion, the hardness of valve element, valve seat to regulating valve, bond strength have higher requirements.Regulation in industry
Valve core, valve seat hardening adopt sintered hard alloy, stainless steel base surface spraying weld hard alloy, stainless steel base surface mostly
The techniques such as vapour deposition, have sintered hard alloy brittle fracture, the problems such as hardened layer is easy to fall off, hardness is inadequate, serious shadow
The degree of regulation and service life of regulating valve are rung.
The content of the invention
The purpose of the application is the defect for prior art, there is provided a kind of wear-and corrosion-resistant regulating valve black box.
The technical scheme of the application is：A kind of wear-and corrosion-resistant regulating valve black box, including valve element and valve seat, in valve element and
The outer surface of valve seat arranges hardened layer.
