Abstract
The invention relates to a pneumatic piston backblowed air switching valve suitable for various occasions on which media are automatically switched or cut off. The switching valve is provided with a three-way valve body with three flow channel openings, wherein a lower channel opening is fixedly connected with a connecting pipe for feeding backblowed air; the upper part of the valve body is fixedly connected with a lower valve cover; the upper end of the lower valve cover is fixedly connected with an upper valve cover and an installation plate for connecting an insulating box; two valve cores are fixed on a valve rod and positioned in a lower cavity of the valve body; and the lower end of the valve rod stretches into a guide sleeve of the connecting pipe, and the upper end of the valve rod stretches out of the upper valve cover, is fixedly connected to an output shaft of a piston executive mechanism, acts with the up and down movement of a piston, and drives the valve cores to switch up and down. The whole valve achieves a two-way zero leakage effect, can be opened and closed within two seconds, and greatly improves the blowing effect of a filter.
Description
Technical field:
The present invention relates to a kind of various occasions that medium is automaticallyed switch or cuts off that are applicable to, be specially adapted to the Pneumatic piston blowback wind switching valve of the automatic control of melamine filter blowback wind.
Background technique:
Blowback wind switching valve is as one of critical valves of Melamine Production, leaks problems such as serious, that switch speed is slow, filler leaks outside and Yi Kayi is stifled in ubiquity at present, badly influenced the utilization efficiency of filter, causes output to descend.
Summary of the invention:
The invention provides a kind of two-way zero leakage that reaches,, promoted the Pneumatic piston blowback wind switching valve of the purging effect of filter significantly less than 2 seconds open and close speed.
The present invention is achieved by the following technical solution: a kind of Pneumatic piston blowback wind switching valve, its major technique feature is that described switching valve adopts the three way valve with three runner mouths, the lower flow passage mouth fixedly connected advance the adapter of blowback air, the fixedly connected bottom flange in valve body top, fixedly connected the bonnet and be connected the mounting plate of usefulness with HEATING BOX in bottom flange upper end, two spools are fixed on the valve rod, be in valve body cavity of resorption position, the valve rod lower end is stretched in the guide sleeve of adapter, the upper end is stretched out bonnet and is fixedly connected on the piston actuator output shaft, with the moving up and down and move of piston, and drive spool and do up and down and switch.
The present invention adopts brand-new three way valve structure, upper and lower two guiding, sealing surface weld deposit department titanium Lay cemented carbide, the long pipe insulation, bonnet then uses double-deck filler to add radiating structure, actuator selects the high thrust high-speed cylinder for use, is equipped with big flow explosion-proof solenoid valve and rapid escape valve again.Complete machine reaches two-way zero leakage, less than 2 seconds open and close speed, has promoted the purging effect of filter significantly.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
Among the figure, 1-takes over, 2-stud, 3-flat gasket, 4-nut, 5-takes over seal ring, 6-spool, 7-valve body, 8-valve bonnet seal circle, 9-stud, the 10-flat gasket, 11-nut, 12-bottom flange, 13-bonnet seal ring, 14-gasket seal, the 15-mounting plate, 16-stud, 17-flat gasket, 18-nut, the 19-bonnet, filler under the 20-, filler among the 21-, 22-spacer, the last filler of 23-, 24-lining, 25-screw, 26-Pneumatic piston actuator.
As shown in Figure 1, this Pneumatic piston blowback wind switching valve adopts the three way valve 7 with three runner mouths, the lower flow passage mouth fixedly connected advance the adapter 1 of blowback air, the fixedly connected bottom flange 12 in valve body top, fixedly connected the bonnet 19 and be connected the mounting plate 15 of usefulness with HEATING BOX in bottom flange upper end, two spools 6,6-1 is fixed on the valve rod 27, be in valve body cavity of resorption position, the valve rod lower end is stretched in the guide sleeve of adapter, the upper end is stretched out bonnet and is fixedly connected on Pneumatic piston actuator 26 output shafts, with the moving up and down and move of piston, and drive spool and do up and down and switch.When the adapter sealing surface was closed, medium was gone into by the A mouth, and the B mouth goes out, and the C mouth is closed; Spool is action upwards, and valve body sealing surface is closed, and blowback air is gone into by the C mouth, and the A mouth goes out, and the B mouth is closed, and implements to purge fast.
