The first hole section and the second hole section are included, first hole section is formed with clamping step, the nozzle alloy with the second hole section junction
Bottom has extended outward to form clamping protrusion, and the clamping protrusion is clamped with the clamping step cooperation.
Further embodiment, the nozzle carrier are equipped with chucking lug.
Further embodiment, the nozzle carrier maintain an equal level with the nozzle alloy bottom section.
Further embodiment, nozzle bore is formed with inside the nozzle alloy, and the nozzle bore aperture is less than described first
Hole section aperture or the second hole section aperture hole section.
Further embodiment, the nozzle carrier bottom outer end face are in six side's boss shapes.
Further embodiment, the nozzle alloy material are hard alloy.
Further embodiment, the nozzle carrier material are medium carbon steel or steel alloy.
Further embodiment, the nozzle internal surface of hole are the clean face of polishing.
This programme has the beneficial effect that：
1st, for the utility model compared with traditional welding form, nozzle carrier uses exclusive hot-mounting process with nozzle alloy,
According to the material property of nozzle carrier during assembling, specific aim setting is carried out to temperature and is precisely controlled, has prevented the spray of normal welding formula
The problem of annealing that mouth is run into causes hardness to reduce.
2nd, to solve the problems, such as that fit dimension is not easy to control, in the utility model, nozzle alloy is set when coordinating with nozzle carrier
Clamping protrusion is put, the clamping protrusion is clamped with the clamping step cooperation, ensure that and axially engage size, and then ensure that
The precision of nozzle.
3rd, close in order to ensure to coordinate between nozzle alloy and nozzle carrier, the endoporus of nozzle alloy is slightly less than the interior of nozzle carrier
Hole, and its mating surface ensures its fit dimension and surface roughness by fine grinding.The end face of nozzle carrier is designed with cooperation
Six side's boss of box spanner, facilitate nozzle removal.
4th, in the present solution, nozzle alloy component is embedded in nozzle cage, during applying working condition difference, nozzle conjunction need to only be increased
The length of gold, nozzle cage interchangeability are good.
5th, in specific implementation, hard alloy can be selected in the material of nozzle alloy, suitable for soil layer, certain uniaxial compressive
The soft rock of intensity, middle hard rock or hard rock.High-quality medium carbon steel or steel alloy can be selected in the material of nozzle carrier.
6th, the nozzle internal surface of hole is the clean face of polishing.Nozzle internal surface of hole for the clean face inner surface finish of polishing compared with
Height, frictional resistance are minimum so that injection loss rate reduces.

It is the utility model high-pressure injection nozzle section schematic diagram that Fig. 1, which is,.
Fig. 2 is the top view of the utility model high-pressure injection nozzle.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
The utility model is further elaborated in embodiment.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
As shown in Fig. 1 Fig. 2, this programme proposes a kind of high-pressure injection nozzle, applied to devices such as high-pressure injection rifle or injector heads
On tool, high-pressure injection nozzle includes nozzle carrier 1 and is arranged on 1 top nozzle alloy 2 of nozzle carrier, and the nozzle carrier 1 is in hollow barrel,
1 hollow space of nozzle carrier is stretched into 2 bottom of nozzle alloy, and is connected together with nozzle carrier 1 by heat pressing process, institute
Stating 1 hollow space of nozzle carrier includes the first hole section 12 and the second hole section 13,12 and second hole section of the first hole section, 13 junction
