The utility model is firstly provided with a transition layer on a valve cap, the inner chamber of a valve body, a closing component and the surface of a valve seat. A working lining made of ceramic material, plasticizer or self-melting alloy is arranged above the transition layer. The utility model has high surface hardness, high hot state structure stability, excellent high-temperature resisting performance, scouring resisting performance, friction resisting performance, corrosion resisting performance and long service life. The utility model is a necessary ideal product for the processing system of thermal power generation, building material production and petrochemical industry.
Description
The utility model relate to a kind of have high temperature resistantly, anti-wash away, the valve of applied corrosion resistant lining coating, belong to universal machine.
At present, in flow systems such as petrochemical industry, building materials production, thermal power generation, often have the graininess goods and materials in the medium.The medium that has itself is exactly a graininess.And the hardness of granule medium is greater than valve body material hardness.Under the condition of high temperature, particularly under 500-900 ℃, particle in its granule medium or the medium washes away the closure member and the valve inwall of valve, seriously corroded, cause and washed away, the quick failure damage in the position of corrosion makes valve extremely short working life, because the frequent valve of changing causes manpower to the user, the great consumption of material resources.Need shut down when crucial to change and cause whole flow system to stop production, cause bigger economic loss to the user.Therefore in above-mentioned production procedure system, be badly in need of providing a kind of high temperature resistant, wear-resisting wiping, anti-ly wash away, corrosion resistant novel valve, to guarantee the working life of valve.
The purpose of this utility model is to provide a kind of high temperature resistant, wear-resisting wiping, the corrosion of anti-granule medium, the valve of long service life at above-mentioned with topic.
The utility model realizes with following technological scheme, high temperature resistantly, anti-washes away, anticorrosion valve, comprises valve rod, valve gap, valve body, closure member and valve seat.It is characterized in that: the surface at the inner chamber of described valve gap, valve body and valve seat, closure member is compounded with transition layer and work lining respectively successively.
Transition layer is AL, Ni alloy, and the work lining is a ceramic layer: i.e. stupalith and plasticizer.Stupalith is AL
2O
3, Cr
3C
2, ZrO
3Or the like; Plasticizer is TiO
2Deng.Work lining also available self-melting alloy layer, self-melting alloy layer can be self-melting alloy such as cobalt-based, Ni-based, iron-based.
Transition layer, working lining layer manufacturing method are:
1, adopt heat spraying method, with AL, Ni spray coating alloy on the inner chamber of valve gap, valve body, the surface of valve seat and closure member, form the transition layer of 0.05-0.3mm, its objective is to be to improve work lining and high base strength.
2, adopt heat spraying method, with stupalith and plasticizer or the self-melting alloy powder is sprayed on respectively on valve gap, body cavity and valve seat, the closure member surface depletion layer, form the thick work lining of 0.1-0.6mm.
The utility model compared with prior art, its product has following advantage:
1, by evidence: adopt Vickers hardness tester, measure work lining hardness and be average (kg/mm more than 900
2) greater than the hardness of 1Cr18Ni9Ti, be lower than friction ractor with alloy with the friction ractor of abrasive particle, only see the wear-resistant time that can improve valve from this point.
2, through test coating anti-thermal shock erosion property
Test conditions: electric furnace KO--11/0.10-0.15 (mm)
20 ± 5 ℃ of cold water of 650 ℃ of 6 circulations
Again through 20 ± 5 ℃ of cold water of 1050 ℃ of 10 circulations
Coating does not come off on inspection
Through test coating and substrate combinating strength σ
b=34.5 (MPa)
Evidence, this product has higher hardness and hot structure stability, have good high temperature resistantly, anti-wash away, corrosion-resistant, scratch-resistant performance, long service life, be comparatively desirable update product in the high temperature flow systems such as petrochemical industry, building materials production, thermal power generation.
