The invention relates to devices for cutting jet of liquid and can be used for separating non-metallic materials.Known nozzle for receiving the cutting jet of liquid containing the fitting with the axial channel of the fluid supply mounted on the nozzle holder with a cavity communicated with the flow channel of the refrigerant. In the cavity is set coaxially with the conical fitting the El. In the insert is made oblique to the axis of the nozzle channels, informing the cavity of the holder with the output part of the axial channel of the liner. The insert is made of vysokoteploprovodnyh material, for example copper. As the refrigerant can be used in liquid nitrogen, freon, refrigerant, etc. substances . However, the disadvantage of this nozzle is output in the environment of environmentally harmful substances.The closest technical solution is the nozzle for receiving the cutting jet of liquid containing socket with a spherical end face and an axial channel of the fluid supply mounted on the nozzle holder, flush mounted in the holder liner with an outer conical surface and the outlet nozzle has a cylindrical shape with a conical inlet part, covering the liner sleeve adjacent its end to the spherical end fitting located with a gap relative addressed to him the butt pad .A disadvantage of the known device is the high energy consumption of equipment for cutting jet of liquid.The proposed solution provides improved cutting properties of the jet when operating at the lower pressure fluid.This dostigao the cash supply of liquid, secured on the holder, the sleeve covering the liner with a conical inlet part, and adjacent its end to the spherical end fitting located with a clearance relative to the addressed end of the liner, unlike the prototype coaxially covering the bushing flush with the holder is made conical heater box, separated from the sleeve and holder of insulating material.The invention is illustrated by the drawing, which shows a nozzle for receiving the fluid cutting jet.A nozzle for receiving the fluid cutting jet contains the socket 1 with a spherical end face 2 and the axial channel 3 fluid supply. On the nozzle 1 is fixed to the holder 4. The holder 4 is installed liner 5 with the outer conical surface and an outlet channel 6 has a cylindrical shape with a conical inlet part and covering the liner 5 and the sleeve 7 is made of soft material. The sleeve 7 is in contact with the end face 8 with a spherical end face 2 of the nozzle 1, which is located with a clearance relative to the addressed end 9 of the liner 5.Coaxially covering the sleeve 7 is flush with the holder equipped with a conical heating box 10, the cylindrical surface 11 which is made of electro">The device operates as follows.The liner 5, ive made wear-resistant material, such as diamond, CBN, sapphire, and is made with a conical outer surface with an angle of 40oinsert in brass bushing 7. Brass bushing 7 with a liner 5 is installed in the holder 4 with the tapered surface, is also equal to the 40o.Before applying the liquid cone insert 10 is heated to operating temperature, with the insulating material 13 prevents the spread of heat to other structural elements of the nozzle. Then through the nozzle 1 will serve high-pressure jet of fluid, which passes through the insert 10, forms a steam cushion from the peripheral region of the jet having a lower kinetic energy due to losses from hydraulic friction on the walls of the sleeve 7. As a result, the output of the nozzle jet is formed from the axial region having a maximum energy.The invention provides improved cutting properties of the jet when operating at the lower pressure fluid. A nozzle for receiving the cutting jet of liquid containing socket with a spherical end face and an axial channel of the fluid supply mounted thereon from the rear side is fitting, located with a clearance relative to the addressed end of the liner, wherein the coaxially with the covering sleeve flush with the holder is made conical heater box, separated from the sleeve and holder of insulating material.
