Abstract
The utility model discloses a porcelain enamel discharge valve body used in chemical industry. The valve body comprises a valve shell, a valve shell flange, a bracket connecting tube and a discharge tube, which are welded and assembled together. The valve shell, the valve shell flange, the bracket connecting tube and the discharge tube are made of carbon steel plates and seamless steel pipes. The porcelain enamel discharge valve body has the characteristics of short tempering time and high porcelain enamel yield, thereby reducing manufacturing cost.
Description
Technical field
The utility model relates to the parts of enamel discharging valve, specifically a kind of enamel discharging valve valve body.
Background technique
The discharging valve of using on the chemical industry reactor should have certain corrosion resistance, so its valve interior surface need carry out enamel processing.At present, the valve body of discharging valve all is that casting forms, because its material is a cast iron, the carbon content height causes one to be decarburization temper time long (generally needing about 12 hours), influences manufacturing efficiency; The 2nd, the enamel difficulty is bigger, and yield rate is low, causes cost of production to rise.
Summary of the invention
In order to solve the problem that the enamel discharging valve valve body production time is long, yield rate is low, the utility model provides a kind of assembled valve body, the short but also enamel easy processing of the not only decarburization temper time of manufacturing of this valve body, yield rate height.
The technological scheme that the utility model provides: valve body is decomposed into several sections such as valve casing, support connecting tube, vomit pipe, flange.Valve casing carbon steel board impact briquetting on the mould of special use, and on valve casing, process support connection pore and vomit pipe attachment hole, make valve casing flange and and valve casing welding assembly with carbon steel board.Go out vomit pipe and support connecting tube according to required with the seamless steel pipe cutting process, process vomit pipe and support connecting tube flange with carbon steel board, and respectively with vomit pipe and support connecting tube welding assembly, dress up valve body with being welded with the vomit pipe of flange and support connecting tube and valve casing soldering group.Valve body, carries out internal surface enamel and fires processing about 15 minutes in tempering in the electric furnace after natural cooling, surface treatment, its enamel up-to-standard rate can reach more than 98%.Effect of the present utility model is that the temper time of valve body is short, enamel up-to-standard rate height, thus reduced the manufacture cost of valve body.
Description of drawings
Fig. 1 is the structural drawing of enamel discharging valve, and 1 is valve body among the figure.
Fig. 2 is the valve body sectional plan view.
Fig. 3 is the plan view of valve body.
Embodiment
With reference to Fig. 1, valve body 5 is connected with reactor by flange, on the handwheel 1 nut is arranged, and rotates handwheel 1, and then the 2 drive spools 6 of the screw mandrel on the support 3 move up and down, and open the hole on the orifice plate 7 when spool 6 moves upward, and emit the material in the reactor; When spool moves downward, then block the tapping hole stop blowing on the orifice plate 7.
See Fig. 2 and Fig. 3, valve body 5 is formed through welding assembly by valve casing 9 and valve casing flange 8, vomit pipe 12 and support connecting tube 10, and flange 13 is housed on the blowing mouth of pipe, and flange 11 is installed on the support connecting tube.Concrete manufacture process is: Q 235 carbon steel board are processed into disk, put into specialized mould and be pressed into valve casing 5.On valve casing 5, stamp out support and connect pore and blowing pore.Be processed into valve casing flange 8 with Q 235 carbon steel board, and and valve casing assembling welding.With seamless steel pipe cutting and process vomit pipe 12 and support connecting tube 10, with cutting of Q235 carbon steel board and Vehicle Processing adpting flange 13 and 11, and respectively with vomit pipe 12, support connecting tube 10 welding assemblies.Vomit pipe 12 and support are taken over 10 to be connect with the blowing pore of valve casing 9 and the eyelet welding of support connecting tube respectively and is assembled into valve body.Valve body carries out surface treatment after the tempering in 15 minutes of 950 degree electric furnace back warps, then valve body 5 internal surfaces are carried out enamel and fire.
Claims (2)
1, a kind of enamel discharging valve valve body is characterized in that, is welded with valve casing flange, vomit pipe and support connecting tube on valve casing, respectively is welded with adpting flange at vomit pipe and support connecting tube top, and valve interior surface has enamel coating.
2, enamel discharging valve valve body as claimed in claim 1 is characterized in that described valve casing and valve casing flange and adpting flange make with the Q235 carbon steel board, and vomit pipe and support connecting tube are made by seamless steel pipe.
