Description

A kind of ball valve that corrosion resistance is high
Technical field
The present invention relates to a kind of ball valves, and in particular to a kind of ball valve that corrosion resistance is high.
Background technique
Valve is widely used in modern society.Especially in water heating pipe fittings technical field, the valve of the prior art has Many kinds mainly have ball valve, angle valve, shut-off valve etc., and wherein ball-valve structure is relatively simple, and the spool of mainly ball valve is simpler It is single.The spool of ball valve is in symmetrical chondritic on the whole, the cylindric through-hole that centre has a perforation whole, in the outer of spool Laterally it is provided with the valve rod groove that is connected with valve rod at sphere centre position, when work, rotation valve rod makes the cylinder of spool The inlet and outlet of shape through-hole alignment ball valve when stopping working, rotate backward the disengaging that valve rod makes the spherical surface of spool be directed at ball valve Mouthful.It is relatively simple for structure due to ball valve, it is easy to operate.So in the very extensive of valve technology field application.And realize ball The major part of the sealing function of valve is spool and sealing ring engaged therewith, and the spool of ball valve occurs wearing or rupture just It easily reveals, scraps entire ball valve, therefore improve the pressing process of highly corrosion resistant ball valve core, keep its more reliable just Seem particularly necessary.Currently, both at home and abroad for valve using more and more extensive, and the environment used is more and more severe, and it is right Also higher and higher in the requirement of valve, therefore, the requirement for spool is also constantly being promoted, the wearability of spool, corrosion resistance, The problems such as heat-resisting ability, is increasingly prominent, and spool is chronically in liquid, and by the impact of liquid, corrosion etc. causes spool Service life greatly shortens, and replacement frequently, considerably increases production cost.
Summary of the invention
The technical problem to be solved by the present invention is to currently, both at home and abroad for valve using more and more extensive, and make Environment is more and more severe, and the requirement for valve is also higher and higher, and therefore, the requirement for spool is also constantly being promoted, The problems such as wearability of spool, corrosion resistance, heat-resisting ability, is increasingly prominent, and spool is chronically in liquid, by liquid Impact, corrosion etc., causes the service life of spool to greatly shorten, and replacement frequently, considerably increases production cost, it is therefore intended that mention For a kind of ball valve that corrosion resistance is high, realizes and a laminated gold plating is coated to the spool face of corrosion resistant ball valve, not only increase The intensity of spool, and the corrosion resistance of spool is increased, wearability, inoxidizability increases the service life of spool, section About a large amount of resource, save the cost.
The present invention is achieved through the following technical solutions:
A kind of ball valve that corrosion resistance is high is coated with corrosion resistant alloy coat on spool, and alloy coat is by nickel-base alloy Powder and powdered graphite composition, Co-based alloy powder chemical component by weight percentage are as follows: Ti:0.5-1.2%, Cr:18- 20%, Si:2.4-4.2%, P:3.0-3.5%, Sn:0.6-1.0%, As:0.02-0.06%, Mo:3.2-3.8%, Fe:5- 10%, C:1-1.5%, Cu:1.2-2.4%, compound rare-earth 1-2.8%, remaining is Ni.
The present invention fits the compound rare-earth of content by being added, and can obviously improve the crystalline structure of metal billet, is allowed to tough and tensile, Cold-forming property improves, and can obtain rare earth element recovery rate to the maximum extent, and be uniformly distributed it in alloy coat, Its intensity, wearability are obviously increased, corrosion resistance obtains unexpected technical effect.
The present invention increases the corrosion-resistant of spool by uniformly coating nickel-base alloy and graphite linings in spool face, resistance to Mill, ability resistant to high temperature add Cu to improve corrosion resistance of the nickel in reductant, and in the flow at high speed seawater of inflation Even passivity；Cr assigns anti-oxidant, sulfuration resistant the ability under the resistance to corrosion and high temperature of nickel under oxidative conditions；Mo is aobvious Write the corrosion stability for improving nickel in reproducibility acid；Cr is added simultaneously in nickel alloy, Mo element can improve it in oxidisability simultaneously Corrosion resistance in medium and reductant.
The present invention realizes and coats a laminated gold plating to the spool face of corrosion resistant ball valve, not only increases spool Intensity, and the corrosion resistance of spool is increased, wearability, inoxidizability increases the service life of spool, has saved a large amount of Resource, save the cost.
Co-based alloy powder chemical component by weight percentage are as follows: Ti:0.7-1.0%, Cr:18-20%, Si:3.0- 3.5%, P:3.0-3.3%, Sn:0.7-0.9%, As:0.04-0.06%, Mo:3.5-3.8%, Fe:6-8%, C:1- 1.2%, Cu:1.8-2.0%, compound rare-earth 1.5-2.5%, remaining is Ni.
