Abstract
The utility model relates to an aluminium alloy ball valve with a ceramic surface. The ball valve comprises an aluminium alloy valve body, a valve cover and a spherical valve core. The inner and the outer surfaces of the aluminium alloy valve body, the valve cover and the spherical valve core are coated with ceramic layers. The ceramic layers adopt micro-arc oxidized ceramic layers or microplasma oxidized ceramic layers or spark electric-discharge sedimentation ceramic layers. The ceramic layers have the good characteristics of high corrosion resistance, high hardness, high wear resistance, strong insulation and the like, so that the ball valve has good economical and environmental benefits and excellent usability.
Description
Technical field:
The utility model relates to a kind of aluminum alloy ball valve of surface ceramic deposition.Be applicable to that domestic water and other need control the occasion of fluid opening/closing.
Background technique:
So-called ball valve is to make open-shut device with the spherical valve core of band manhole, and spherical valve core rotates with valve rod, to realize the valve of switching motion.
The critical piece of ball valve is valve body, valve gap and spherical valve core.They are made with materials such as brass, steel, stainless steel and aluminum alloys usually.Its wear resistance, corrosion resistance and insulating properties are relatively poor.
Summary of the invention:
The purpose of this utility model is: the aluminum alloy ball valve that a kind of surface ceramic deposition is provided.This ball valve has the anti-corrosion capacity of excellent convection cell, has improved the life-span, very environmental protection again in production and using process.
The preparation method of this surface ceramic deposition aluminum alloy ball valve is as follows:
1. aluminum alloy material: the trade mark is 6061 also can be the wrought aluminium alloy of other trade mark, as 2 * * *, 4 * * *, 5 * * *, 7 * * * wait the aluminum alloy of series.Some cast aluminium alloy also can be used as raw material, as 1 * *, 2 * *, 3 * * cast aluminium alloy of series.
2. the production of ball valve blank parts: the blank of ball valve critical piece such as valve body, valve gap, spherical valve core, can be by forging and pressing or cast or, finishing moulding by turning.
3. machining:, satisfy size, the shape need of ball valve element by blank being carried out machine cut processing.
4. surface ceramic deposition is handled: each critical piece of ball valve is carried out surface ceramic deposition handle.This processing is to finish on the aluminum alloy surface ceramic special device.
5. the assembling of ball valve: valve body (4), valve gap (1), spherical valve core (5) and other accessory of surface ceramic deposition are assembled up the complete ball valve of composition.Other accessory is meant valve rod (2), handle (3) etc.Valve rod (2) and handle (3) can be the aluminum alloys of surface ceramic deposition.Also can be steel and Cuprum alloy.With the fluid surface of contact be ceramic layer (6) on the ball valve, and pottery has highly corrosion resistant, makes ball valve have the anti-corrosion capacity of excellent convection cell, thus also not convection cell produce and pollute, have longer working life.Stupalith has high corrosion resistance, high hardness, high wear resistance, strong insulating properties etc., has also had these characteristics so also just given the surface of surface ceramic deposition aluminum alloy ball valve.
Surface ceramic deposition aluminum alloy ball valve has good Economy, the feature of environmental protection and usability:
1. Economy: aluminum alloy is low weight on raw material, and price is relatively cheap, and is aspect processing, easy to process, technology is easy.
2. the feature of environmental protection: because the highly corrosion resistant of ceramic layer.So convection cell does not produce and pollutes.While aluminum alloy surface ceramic processing procedure is with respect to plating, oxidation and other surface treatment mode, more environmental protection, cleaning.
3. usability is superior: because aluminum alloy is low weight, so ball valve is also light, and carrying and easy for installation.Simultaneously high corrosion resistance makes long service life, and the surface can also be processed into multiple color, has better visual sense of beauty.
For achieving the above object, design of the present utility model is:
Surface ceramic deposition is a kind of advanced technologies of novel aluminum alloy surface modification.Handle by aluminum alloy material being carried out surface ceramic deposition, can be at process to produce ceramic layer on surface.The composition of surface ceramic layer and structural feature are to have a certain proportion of crystalline state α-Al
2o
3And r-Al
2o
3So it has the characteristic of stupalith, as corrosion-resistant, high hardness, wear-resisting, strong insulation etc.Surface ceramic deposition is also referred to as differential arc oxidation, micro-plasma oxidation, sparkover deposition etc. sometimes.
The utility model is on the valve body of being made by aluminum alloy, valve gap and spherical valve core, handles by differential arc oxidation, at process to produce ceramic layer on surface, utilizes the inherent characteristic of pottery, thereby improves some usability of ball valve.
According to the design of above-mentioned model utility, the utility model adopts following technical proposals:
A kind of surface ceramic deposition aluminum alloy ball valve comprises aluminum alloy valve body, valve gap and spherical valve core, and it is characterized in that has ceramic layer on the inner and outer surface of described valve body, valve gap and spherical valve core.
Above-mentioned ceramic layer is an arc differential oxide ceramic layer, or little plasma ceramic layer, or the sparkover deposited ceramic layer.
The utility model has following conspicuous substantive distinguishing features and advantage compared with prior art: ball valve of the present utility model, its valve body, valve gap and spherical valve core are that aluminum alloy material is made, and on its inner and outer surface ceramic layer are arranged.Ceramic layer has good characteristics such as high wear resistance, high corrosion resistance, high hardness and strong insulating properties, makes this ball valve have good Economy, the feature of environmental protection and usability.
