Abstract
The utility model relates to a dedicated cock valve for hydrochloric acid smelting, which comprises a valve body, a valve cover, a valve rod and a cock. A medium passage is formed in the valve body, and an erosion-proof and abrasion-proof lining is arranged on the surface of the medium passage to form a structure which is resistant to strong acid abrasion and erosion. The dedicated cock valve for hydrochloric acid smelting, provided by the utility model, has a reasonable structure that the erosion-proof and abrasion-proof lining which is arranged on the surface of the medium passage has high hardness and good erosion resistance, and is not liable to be worn in the case of exposure to a strong-acid strongly-corrosive medium containing a large amount of particles. The fast damage of the valve body is eliminated, and the reliability of the cock valve is greatly improved. The dedicated cock valve for hydrochloric acid smelting can meet the requirements for smelting process pipelines under strict conditions, and ensure safe and stable operation for a long time.
Description
Technical field: the utility model relates to a kind of stopcock, especially for the stopcock on smelting equipment.
Background technique: in the smelting projects such as nickel, zinc, copper, smelting process is often used the strong acid deep-etching materials such as hydrochloric acid as smelting medium, and in medium, generally contain a large amount of particles, quality is larger, washing away and wearing and tearing very strong stopcock while flowing, flow through after medium channel and even can within a short period of time valve body be washed away hole, the applying working condition of valve is very harsh, is easy to damage.Although now available rare metal of being able to bear strong corrosion is manufactured stopcock, the antiscour polishing machine of material is all strong not, and the reliability that stopcock uses in smelting process pipeline is not high.
Summary of the invention: for the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, service-strong hydrochloric acid is smelted plug valve special.
The utility model comprises valve body, valve gap, valve rod and cock, is provided with medium channel in valve body, is also provided with resistance to erosion anti-wearing liner on the surface of medium channel, forms anti-strong acid wearing and tearing and washes away structure.
Of the present utility model rational in infrastructure, on the surface of medium channel, be also provided with resistance to erosion anti-wearing liner, hardness is high, scour resistance is good, not easy to wear under the strong acid strong corrosive medium that contains a large amount of particles washes away yet, avoided the Rapid Damage of valve body, greatly improved the reliability of stopcock, can meet the harsh working condition requirement of smelting process pipeline, long-term safety stable operation.
Below in conjunction with drawings and Examples, further illustrate the utility model.
Accompanying drawing explanation: Fig. 1 is embodiment's main structure schematic diagram.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment: as depicted in figs. 1 and 2, valve body 1 connects valve gap 2, and cock 3 is connected to valve rod 4 lower ends, is provided with medium channel 5 in valve body 1, is also provided with resistance to erosion anti-wearing liner 6 on the surface of medium channel 5, forms anti-strong acid wearing and tearing and washes away structure.Valve body 1 can adopt the rare metal manufacture of being able to bear strong corrosion, and resistance to erosion anti-wearing liner 6 can adopt pottery or other nonmetallic material to make, and can resistance to wear, antiscour.
In actual use, because the granule content in medium, the velocity of medium flow direction etc. all may be different, resistance to erosion anti-wearing liner 6 in the present embodiment is split groupware type, can adjust quantity, position and manufactured materials etc. according to actual conditions, reach better using effect, further improved the reliability of stopcock.
