Abstract
The utility model relates to a water-cooling vacuum isolation valve which is in a flat-plate structure and adopts double-layer stainless-steel water cooling, i.e. an upper body and a lower body of the isolation valve replace the rotary extrusion or the blasting formation of a circular arc camber by using the flat-plate structure. A water flow passage is an annular water flow passage, an upper cover and a lower cover are directly formed by using lathe processing and mill processing and can bear the vacuum degree of 5*10-4Pa, and the valve can bear the hydraulic pressure of 1.2MPa. Under the combined action of the water communication pressure of 0.6MPa and the vacuum degree of 5*10-4Pa, the valve has favorable sealing and no leakage. The utility model solves the problems of manufacture of an isolation valve of a vacuum induction smelting furnace and import dependence of the components of valve bodies. The unit price of imported isolation valves is 187000 yuan/set, and the water-cooling isolation valve only needs 22000 yuan. The product not only is suitable for like medium-sized/small-sized vacuum smelting equipment but also can replace like products produced by different nations. Because of simple structure and low price, the utility model has popularization value.
Description
Technical field
The utility model relates to the founding of oriented monocrystalline precision casting vacumn induction special-purpose separating valve, particularly water-cooled vacuum separation valve.
Background technique
Vacuum separation valve is used for the valve opening and closed mechanism between oriented monocrystalline vacumn induction casting furnace working chamber and the mold chamber.
The manufacturing technology of separating valve is one of crystallographic orientation vacumn induction casting furnace charging mechanism, water-cooled vacuum crystallizer three big technological difficulties.Play the locellus operation in the casting of blade of aviation engine vacuum precision, the effect of increasing work efficiency guarantees that simultaneously the founding chamber remains vacuum in the whole process of founding, not broken atmosphere.
Vacuum separation valve and common valve are differing greatly aspect structure and the working environment.Because vacuum separation valve is to work under hot vacuum environment, the working environment of this valve requires: the one, guarantee that O-ring seal can access sufficient cooling under the baking of long-time high temperature formwork; The 2nd, valve tolerance atmospheric pressure.
Existing external vacuum separation valve adopts parallel flow channel, double-deck arc surface structure, and as shown in Figure 3, its preparation process is last arc surface, arc surface adopts explosive forming down, and moulding needs secondary operations later on.Its stiffening rib adopts digital control processing to finish.Distance between separating valve upper body and the lower body arc surface is not contour design, and manufacturing process is loaded down with trivial details; Because the passage thickness differs, current are not smooth, influence cooling effect, make O-ring seal Yin Gaowen easily and wear out.18.7 ten thousand yuans of the external whole device prices of vacuum separation valve, the order cycle time was generally for 12 week～15 weeks, had seriously restricted the continuous production of equipment.
Summary of the invention
The technical problem that solves
The technical problem that the utility model water-cooled vacuum separation valve will solve is, 8 * 10
-4Under the Pa vacuum state, valve body works long hours does not have distortion, and the seal groove ne-leakage also has good water-cooled effect; Avoid using explosion and digital control processing manufacturing, reduce cost, shorten the manufacturing cycle.
Technological scheme
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model is a slab construction, the double-layer stainless steel water-cooled, promptly separating valve up and down the body and function slab construction substitute circular arc camber, spinning or explosive forming, flow channel are annular flow channel, loam cake and lower cover are with Vehicle Processing and mill the processing straight forming.Have middle part bearing pin, periphery to be connected bearing pin between separating valve loam cake and the lower cover, connect strengthening, bearing pin is distributed as: periphery connection bearing pin 5 is evenly distributed on diameter 350mm place, and all pin diameters are 50mm, and material is Austenitic Stainless Steel 1Cr18Ni9Ti.Bearing pin adopts the argon arc welding of upper and lower bottom surface to fill welding manner and fixes the integral solder moulding.Moulding becomes a firm integral body with rear valve body, has solved the problem on deformation of valve body under the vacuum state.
Be provided with cooling water passage in the valve body.Vacuum insulation valve upper cover and lower cover are respectively annular boss and groove, and the two make-up forms the ring-type cooling channel naturally.For preventing electromagnetic induction, and the water-cooled non-corroding, separating valve loam cake, lower cover, bearing pin are selected Austenitic Stainless Steel 1Cr18Ni9Ti for use.
Beneficial effect
The utility model water-cooled vacuum separation valve proves by strength check and the practical application that comes 2 years more, can tolerate 5 * 10
-4The degree of vacuum of pa, valve can bear 1.2MPa hydraulic pressure.In 0.6MPa water flowing pressure and 5 * 10
-4Under the acting in conjunction of pa degree of vacuum, this valve seal is good, does not have to leak.The manufacturing of vacuum induction melting furnace separating valve and the dependence on import problem of valve body parts have been solved.
The separating valve unit price of import is 18.7 ten thousand a yuan/cover RMB, and the utility model water-cooled separating valve only needs 2.2 ten thousand yuans.This product is not only applicable to similar middle-size and small-size vacuum smelting equipment, and can substitute the like product that country variant is produced.Since simple in structure, cheap, promotional value had.

Embodiment
Implement water-cooled vacuum separation valve of the present utility model, shown in Fig. 1～2.Its water-cooled vacuum separation valve is a slab construction, the double-layer stainless steel water-cooled, and the separating valve valve body is by separating valve lower cover 1, and separating valve loam cake 2 is formed.700 millimeters of separating valve loam cake 2 diameters.Turnover cooling water connecting tube 4 is arranged in the valve body, and separating valve loam cake 2 and separating valve lower cover 1 are respectively annular boss and groove, and the two make-up forms the ring-type cooling channel naturally.Separating valve loam cake 2 and the 1 usefulness Vehicle Processing of separating valve lower cover and mill the processing straight forming, have middle part bearing pin 3, periphery to be connected bearing pin 5 between separating valve loam cake 2 and the separating valve lower cover 1, to strengthen connection, bearing pin is distributed as, periphery connects bearing pin 5 and is evenly distributed on diameter 350mm place.All pin diameters are 50mm, and material is Austenitic Stainless Steel 1Cr18Ni9Ti.Bearing pin adopts the argon arc welding of upper and lower bottom surface to fill welding manner and fixes the integral solder moulding.Moulding becomes a firm integral body with rear valve body, has solved the problem on deformation of valve body under the vacuum state.
