Abstract
A corrosion-resistant metal ball valve comprises a floating ball valve and a fixed ball valve, and is composed of a valve body, a valve clack and a valve rod, and is characterized in that the inner cavity of the valve body, the surface of the valve clack and an overflowing part are provided with fusion bonding epoxy powder coating layers, and the thickness of the fusion bonding epoxy powder coating layers is 0.3-1.2 mm. The utility model discloses better corrosion resisting property and low cost have.
Description
The utility model relates to the valve in the transfer line, and a kind of corrosion resistant metal ball-valve is provided especially.
Because the unique texture of ball valve can be realized control comparatively accurately to the flow of pipeline medium fluid, and with low cost, thereby be widely used in the every field such as pipe network system of oil, chemical industry, public facilities.In general, the medium that pipeline is carried is complicated, and the valve in the pipeline is also had certain corrosive action, is corrosion protection, and the more common practice is to adopt stainless steel material to make, and this has just improved the cost of valve virtually.
The purpose of this utility model is to provide a kind of corrosion resistant metal ball-valve, and it has decay resistance and with low cost preferably.
The utility model provides a kind of corrosion resistant metal ball valve, comprise Float ball valve and Fixed ball valve, form by valve body (1), flap (2), valve rod (3), it is characterized in that: the inner chamber of valve body (1), flap (2) surface and overcurrent position all are provided with smelting combined epoxy powder coating layer (4), and thickness is 0.3～1.2mm.
The utility model floating coat (4) thickness is preferably 0.5～0.8mm.
Used corrosion-inhibiting coating is the commercially available prod in the utility model, and as the SEBF anticorrosive paint of Metal Corrosion and Protection Inst., Chinese Academy of Sciences's development and exploitation, it has following characteristics:
1. stable chemical performance, oil resistant, acidproof, alkaline-resisting, seawater corrosion resistance.
2. strong adhesion, excellent in cushion effect.
3. abrasion resistance properties good (in corrosive environment) is five times of cast iron.
4. serviceability temperature is extensive, is-40～150 ℃ in the air, is 0～100 ℃ in the solution, in the seawater 〉=and 100 ℃ (because experimental condition is only done seawater＞110 ℃ experiment).
5. the anticorrosive coat thickness range is at 30～3000 μ m, can carry out car, cuts, digs, machining such as mill.
6. anticorrosive coat even compact, smooth smooth, resistance is little, the efficiency of transmission height.
7. anticorrosive coat is nontoxic, tasteless, pollution-free.
8. long service life (according to the foreign data introduction, similar anticorrosive coat, safe operation is more than 30 years), price performance is much better than other process for protecting.
A layer thickness is anti-corrosion uniformly, wearing layer owing to employing high-performance adhere, thermosetting epoxy powder form at the metal surface of thick metal ball-valve melting and solidification for the utility model, makes metal ball-valve have stronger wear-corrosion resistance.Having overcome in the past, metal ball-valve has enlarged the scope of its application in the shortcoming of the occasion corrosion resistance difference of directly buried pipeline, conveying Korrosionsmedium.This metal ball-valve corrosion-resistant coating has high mechanical strength and impact resistance, good anti-corrosion, wear-resisting property, and prevent electrochemical corrosion.The utility model can be widely used in heat supply, petrochemical industry, electric power, shipbuilding, cement, food sanitation and pharmaceutical industries.Below by embodiment in detail the utility model is described in detail.
Accompanying drawing 1 is the Float ball valve structural representation.
Accompanying drawing 2 is the Fixed ball valve structural representation.
Embodiment 1
As shown in Figure 1, be floating structure, be made up of valve body (1), flap (2), valve rod (3) that the inner chamber of valve body (1), flap (2) surface and overcurrent position all are provided with smelting combined epoxy powder coating layer (4), thickness is about 0.5mm.
As shown in Figure 2, be stationary structure, be made up of valve body (1), flap (2), valve rod (3) that the inner chamber of valve body (1), flap (2) surface and overcurrent position all are provided with smelting combined epoxy powder coating layer (4), thickness is about 0.8mm.
Claims (2)
1. corrosion resistant metal ball valve, comprise Float ball valve and Fixed ball valve, form by valve body (1), flap (2), valve rod (3), it is characterized in that: the inner chamber of valve body (1), flap (2) surface and overcurrent position all are provided with smelting combined epoxy powder coating layer (4), and thickness is 0.3～1.2mm.
2. according to the described corrosion resistant metal ball valve of claim 1, it is characterized in that: coating (4) thickness is 0.5～0.8mm.
