Description

With high-intensitive low-load type butterfly valve
Technical field
The present invention relates to a kind of butterfly valves, and in particular to has high-intensitive low-load type butterfly valve.
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 butterfly valve, angle valve, shut-off valve etc..Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for The butterfly valve of the switch control of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, reaches out around valve shaft rotation A kind of valve for opening and closing.And realize that the major part of the sealing function of butterfly valve is spool and sealing ring engaged therewith, butterfly Just easily revealing occurs wearing or rupturing in the spool of valve, and scraps entire butterfly valve, therefore improve the corrosion resistant of butterfly valve core Erosion makes its more reliable just seem particularly necessary.Currently, using ring that is more and more extensive, and using for valve both at home and abroad Border 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, spool The problems such as wearability, corrosion resistance, heat-resisting ability, is increasingly prominent, and spool is chronically in liquid, rotten by the impact of liquid Erosion etc., causes the service life of spool to greatly shorten, 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 having high-intensitive low-load type butterfly valve, realizes and a laminated gold plating is coated to the spool face of corrosion-resistant butterfly valve, not only The intensity of spool is increased, and increases the corrosion resistance of spool, wearability, inoxidizability, increase spool uses the longevity Life, has saved a large amount of resource, save the cost.
The present invention is achieved through the following technical solutions:
With high-intensitive low-load type butterfly valve, it is coated with corrosion resistant alloy coat on spool, alloy coat is by Ni-based 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%, W:4- 5.5%, Zr:2.6-3.4%, 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 butterfly valve, not only increases the intensity of spool, and And the corrosion resistance of spool is increased, and wearability, inoxidizability increases the service life of spool, a large amount of resource has been saved, 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%, W:4.5-5%, Zr:2.8- 3.2%, Fe:6-8%, C:1-1.2%, Cu:1.8-2.0%, compound rare-earth 1.5-2.5%, remaining is Ni.
Co-based alloy powder chemical component by weight percentage are as follows: Ti:0.5%, Cr:18%, Si:2.4%, P:3.0%, Sn:0.6%, As:0.02%, Mo:3.2%, W:4%, Zr:2.6%, Fe:5%, C:1%, Cu:1.2%, compound rare-earth 1%, Remaining is Ni.
Co-based alloy powder chemical component by weight percentage are as follows: Ti:0.9%, Cr:19%, Si:3.2%, P:3.3%, Sn:0.8%, As:0.04%, Mo:3.5%, W:5.5%, Zr:3.4%, Fe:8%, C:1.3%, Cu:1.9%, compound rare-earth 2%, remaining is Ni.
