Abstract
The utility model discloses an adjusting valve, which belongs to field of mechanical parts, and in particular relates to a valve. The adjusting valve comprises a valve core main body, the characteristics of the adjusting valve is that the outer surface of the valve core main body is sequentially provided with a bonding layer and an anti-corrosion and wearing-resistant layer. For the utility model, the outer surface of the valve core main body is sequentially provided with the bonding layer and the anti-corrosion and wearing-resistant layer, and the anti-corrosion and wearing-resistant layer is firmly combined with the peripheral wall substrate through the bonding layer, which is not easy to fall off and is wear-resistant.
Description
Technical field
The utility model belongs to the component of machine field, is specifically related to a kind of valve.
Background technique
Modulating valve is divided into electric control valve, pneumatic control valve and the modulating valve that surges, in the automatic control that modernization industry is produced, modulating valve plays an important role, yet valve body uses sealing surface frequently causes owing to switch after a period of time wearing and tearing, the wearing and tearing of media flow and the reasons such as extruding erosion of corrosion and impurity for a long time, can make spool face form spot, cut equivalent damage, can cause valve body to lose efficacy when serious, cause serious consequence.General this damage is difficult for repairing, and promptly need change whole valve in case produce, and expense is high, and it is especially true to change the inlet adjusting valve.If whole spool is adopted the high-strength abrasion-proof material, its working life can effectively be prolonged, yet not only processing difficulties and fabricating cost are high like this, lose more than gain.If common coating is set on working surface, itself and base material bonding effect are poor, easily peel off, and be impracticable.Therefore, the modulating valve of design the wear-resistant and economic saving of a kind of spool, easily processing has been the task of top priority.
The model utility content
The technical problem that the utility model solved is: designed a kind of modulating valve, spool is wear-resistant, long service life.
The technological scheme that its technical problem that will solve the utility model adopts is: design a kind of modulating valve, comprise the spool body, it is characterized in that order is provided with bonding layer and anticorrosion antiwear layer on the outer surface of spool body.
A kind of modulating valve described in the utility model is characterized in that bonding layer is the nickel alloy powder sprayfused coating, and bondline thickness is 0.2～0.5mm.The anticorrosion antiwear layer is a nickel tungsten powder sprayfused coating, and the anticorrosion antiwear layer thickness is 0.05～5mm.This external surface of spool is level and smooth cambered surface.
The beneficial effect that the utility model had is:
1. the utility model order on this external surface of spool is provided with bonding layer and anticorrosion antiwear layer, and the anticorrosion antiwear layer passes through the bonding layer strong bonded on the periphery wall base material, and is incrust and wear-resistant.
2. bonding layer is the nickel alloy powder sprayfused coating, and the anticorrosion antiwear layer is a nickel tungsten powder sprayfused coating, makes machining operation easy and meet the requirement of aspect speciality.Bondline thickness is 0.2～0.5mm, and the anticorrosion antiwear layer thickness is 0.05～5mm, and the thickness setting is not only scientific and reasonable but also economical and practical.
3. this external surface of the utility model spool is level and smooth cambered surface, is convenient to each protective layer of even coating, and can reduce the impact force of valve inner fluid to spool, reduces to impact loss.
4. the utility model is reasonable in design, and fabricating cost is low, suitable penetration and promotion and industrialization volume production.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion partial enlarged drawing of Fig. 1;
Among the figure: 1. spool body, 2. bonding layer, 3. anticorrosion antiwear layer.
Embodiment
Embodiment one
A kind of modulating valve described in the utility model, order is provided with bonding layer 2 and anticorrosion antiwear layer 3 on the outer surface of spool body 1, and anticorrosion antiwear layer 3 passes through bonding layer 2 strong bonded on the periphery wall base material, and is incrust and wear-resistant.Bonding layer 2 is the nickel alloy powder sprayfused coating, and bonding layer 2 thickness are 0.2mm.Anticorrosion antiwear layer 3 is a nickel tungsten powder sprayfused coating, and anticorrosion antiwear layer 3 thickness are 0.05mm.The outer surface of the utility model spool body 1 is designed to level and smooth cambered surface, is convenient to each protective layer of even coating, and can reduce the impact force of valve inner fluid to spool, reduces to impact loss.The utility model can utilize the modulating valve of scrapping of excessive wear to process, the not only economic development of saving but also helping recycling economy.Specific process is as follows:
1) will scrap lathe centering on the spool body 1 of modulating valve, car removes fray;
2) the spraying plating bonding layer 2, and bonding layer 2 adopts the nickel alloy powder coating, and thickness is 0.2mm, more than processing temperature 60--120 ℃;
3) spray anticorrosion antiwear layer 3, anticorrosion antiwear layer 3 adopts the nickel tungsten powder, and coating thickness is 0.05mm, and processing temperature is stayed mill amount 0.15-0.25mm more than 300 ℃;
3) go up grinding machine and be milled to the size that cooperates with sealed mouth;
4) first-class bolt, water flowing, Ventiation Testing, qualified can coming into operation once more.
