Abstract
The utility model discloses a supersonic liquid jet generator, which comprises an outer chamber which is provided inside in order with a free piston, a regulating ring, a rubber gasket, a diaphragm, an O-shaped seal ring, a liquid chamber, an O-shaped seal ring, a diaphragm, a rubber gasket and a nozzle, the outer part of which has a circular stair and a top flange that matches the circular stair. The top flange and the outer chamber are fixed with inner hexagon screws; the outer chamber is fixed in a supporting flange through threads; the outer chamber has an outer threads interface in the back end outer side, which is connected with the inner threads of the supporting flange; and the O-shaped seal ring is positioned in the contact face of the outer chamber and the supporting flange. The utility model can generate the liquid jet at the speed of 2km/s to 5km/s or even higher, can generate supersonic liquid jet in vacuum or high pressure air environment. The utility model also has the advantage of generating supersonic jet in all air environment and air any angle, therefore the new generator can be a new experimental method in studying liquid atomization process.
Description
Technical field
The utility model relates to a kind of hypersonic liquid jet generator.
Background technology
Liquid jet has solid jet and pulsing jet.Method with solid jet also can not be increased to the pressure of fluid 1000MPa technically to 10GPa or higher pressure, therefore also can not produce continuous hypersonic liquid jet.The device that produces the pulse liquid jet has adopted the method with piston impact extruding liquid, or with the method for packaged explosive.Though packaged explosive has been used to produce metal jet, but owing to costing an arm and a leg and danger of it, it also is not widely used in the generation liquid jet, and for low surface tension and the liquid that is atomized easily, the liquid jet that produces with packaged explosive has very strong unstability.With the method for piston impact extruding liquid, saying so theoretically to reach high nozzle exit pressure arbitrarily, as long as piston has sufficiently high speed.Yet for engineering material commonly used, when nozzle exit pressure was higher than 1500MPa, nozzle will deform and destroy, and the liquid jet device can only disposablely use usually, causes very big waste.
Summary of the invention
Purpose of design of the present utility model provides a kind of hypersonic liquid jet generator.
It has outer chamber, in outer chamber, be provided with free-piston, adjustable ring, rubber washer, barrier film, O RunddichtringO, liquid chamber, O RunddichtringO, barrier film, rubber washer, nozzle successively, there are a ring-shaped step and the top flange that is complementary in the nozzle outside, top flange and outer chamber are fixed with soket head cap screw, outer chamber is fixed on the pivot flange by screw thread, the outside, rear end of outer chamber is provided with the external screw thread interface, be connected with the internal thread of pivot flange, the contact-making surface of outer chamber and pivot flange is provided with the O RunddichtringO.
The utility model is the key technology that produces utmost point supersonic speed pulse liquid jet, and its advantage is a simplicity of design, easy to use, and the piston that operating speed is lower produces the higher liquid jet of speed, carries out the cutting and the processing of various materials.By this technology, solve nozzle short technical barrier in service life in using the hypersonic liquid jet process, give full play to the effect of hypersonic liquid jet.The utility model can generation speed be the liquid jet of 2km/s to 5km/s or more speed.Nozzle and liquid chamber can be used more than five times, and top flange and outer chamber can be used more than 50 times.Can in vacuum or high pressure gas environment, spray hypersonic liquid jet.Therefore the utility model also has can become a kind of new laboratory facilities of research atomization of liquid process in arbitrarily angled advantage of spraying hypersonic liquid jet down under all gases environment.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The hypersonic liquid jet generator has outer chamber 14, in outer chamber 14, be provided with free-piston 11 successively, adjustable ring 10, rubber washer 9, barrier film 8, O RunddichtringO 7, liquid chamber 5, O RunddichtringO 4, barrier film 3, rubber washer 2, nozzle 1, there are a ring-shaped step and the top flange 12 that is complementary in nozzle 1 outside, top flange 12 is fixing with outer chamber 14 usefulness soket head cap screws 13, outer chamber 14 is fixed on the pivot flange 16 by screw thread, the outside, rear end of outer chamber 14 is provided with the external screw thread interface, be connected with the internal thread of pivot flange 16, outer chamber 14 is provided with O RunddichtringO 15 and 17 with the contact-making surface of pivot flange 16.
Said liquid chamber 5 is taper, is provided with liquid 6 in the liquid chamber 5.
The hypersonic liquid jet generator has inside and outside double-layer structure, and internal layer has nozzle, liquid chamber, adjustable ring, and skin has top flange and outer chamber, and outer chamber is fixed on any one pivot flange with the external screw thread of its rear end.In liquid chamber, the barrier film of rear and front end is compressed by rubber washer and O RunddichtringO respectively again fluid column by the diaphragm seal at two ends.Barrier film is plastic sheeting normally.Nozzle, liquid chamber, adjustable ring are fixed between top flange and the outer chamber by soket head cap screw.Experimental results show that employing is respond well along eight soket head cap screws of axial symmetry layout.The nozzle interior cavity has the convergent molded lines, is used for accelerating fluid, and the nozzle outside has ring-shaped step and top flange coupling.It is conical that liquid chamber inside is, the equal diameters of the diameter of circular cone front end and nozzle rear end, and the diameter of circular cone rear end is equal to or slightly greater than the diameter of cylindrical piston.Pressure with increase liquid takes place to focus in the conical interior shape of liquid chamber, the shock wave that produces in the time of can making piston slap liquid, and moving piston is played the effect of brake.The change of atomizing of liquids volume can realize by the axial length that changes liquid chamber, as long as mix the adjustable ring of respective length.The material of cylindrical piston is used high molecular polymer usually.When the rearward end of piston slap liquid chamber, the shock wave that is produced by bump makes liquid obtain quickening for the first time after by fluid column, and liquid obtains quickening for the second time after the liquid that is accelerated enters negative throat noz(zle), thereby produces hypersonic liquid jet at jet expansion.Energy by the generation of piston impact liquid chamber, passed to the front adjacent nozzles, ring-shaped step by the nozzle outside passes to top flange with energy again, by soket head cap screw energy is passed to outer chamber in opposite direction again, by the screw connection structure of outer chamber rear end and pivot flange, energy has been passed to pivot flange at last.Like this, piston absorbs the supported flange of impact energy of device, suppresses or has reduced and impacted the damage that liquid chamber and nozzle are caused.The outer chamber of heavy wall has limited being radially expanded under the super-pressure effect of liquid chamber, and the rubber washer that is installed in the liquid chamber two ends has cushioned the axial expansion of liquid chamber again, has avoided nozzle directly to be subjected to the impact of liquid chamber.In addition, the contact-making surface of outer chamber and pivot flange is sealed by the O sealing ring, as long as pivot flange and miscellaneous part are formed enclosure space, just can carry out spraying hypersonic liquid jet under all gases environment.
