Description
Technical field
It the utility model is related to Features of Auxiliary Nozzle on Air-jet loom, more particularly to a kind of air-jet loom auxiliary spray of reliable wefting insertion
Mouth.
Background technology
Main and auxiliary nozzle is with the filling insertion way that the filling insertion way that Profiled Reed is combined is air-jet loom main flow, in wefting insertion process
In, pilot jet ensures that weft yarn passes through shed open, is the Primary Component that Profiled Reed formula air-jet loom carries out relay wefting insertion, still
Gas consumption accounts for the 3/4 of complete machine gas consumption amount.Wefting insertion quality, wefting insertion efficiency and the energy consumption size of air-jet loom largely by
The influence of pilot jet structural behaviour.The nozzles for using single spraying hole in the prior art more, although its convergence is good, speed is fast,
High is required to fabric, easy-to-draw staplings yarn.Diplopore pilot jet projects ability and is better than single hole, but traditional diplopore pilot jet wefting insertion is not
It is enough steady, especially air pressure supply it is unstable in the case of, it is easier to there is staplings mixed weft.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of air-jet loom of reliable wefting insertion
Pilot jet, it is simple in construction, the optimization of diplopore pilot jet flow velocity had both been realized, has ensured the stationarity of wefting insertion again.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of Features of Auxiliary Nozzle on Air-jet loom of reliable wefting insertion, including shell, the inside of the shell is middle air chamber, described
Shell includes upright drosal part and nauropemeter sidepiece, and the nauropemeter sidepiece tilts to the upright drosal part, and the two converges shape
Into the vertex of a cone；Characterized in that, being provided with upper and lower two spray orifices on the nauropemeter sidepiece, the cross sectional shape of two spray orifices is circle
Shape and two injection diameters are of different sizes；The diameter of upper spray orifice is less than the diameter of lower spray orifice, two spray orifices and internal middle air
Chamber penetrates；A diameter of 0.8-1mm of the upper spray orifice, a diameter of 1.3-1.5mm of the lower spray orifice, the center of circle of upper and lower spray orifice
Away from for 1.8-2.0mm；Poroelasticity film is installed on the inwall of the nauropemeter sidepiece, is uniformly distributed on the poroelasticity film
There are multiple stomatas, lower spray orifice is completely covered poroelasticity film close to one end of middle air chamber.
Further, a diameter of 0.8mm of the upper spray orifice, a diameter of 1.4mm of the lower spray orifice, upper and lower spray orifice
Distance of center circle is 1.8mm.
Further, the shell is made of zirconia ceramics material.
More traditional pilot jet is had and had as follows by the Features of Auxiliary Nozzle on Air-jet loom of reliable wefting insertion provided by the utility model
Beneficial effect：1st, the structure of pilot jet diplopore is optimized, realizes the optimization of flow velocity, reaches economical and practical performance and maximizes；
The 2nd, porous elastic material is installed at lower spray orifice air inlet, when air-jet loom supply air pressure changes, pilot jet
The air-flow of stable homogeneous can be provided, the angle of jet-stream wind will not change；3rd, shell 1 is overall uses zirconia ceramics material
Material, surface roughness is extremely low, and has high toughness and intensity, and it is steady to jet to further reduce nozzle surface fine structure
Qualitatively influence.
Brief description of the drawings
Fig. 1 is the front view of the Features of Auxiliary Nozzle on Air-jet loom of the reliable wefting insertion of the utility model.
Fig. 2 is Fig. 1 side sectional view.
Fig. 3 is the gas cell distribution schematic diagram of poroelasticity film in Fig. 2.
Embodiment
The utility model provides a kind of Features of Auxiliary Nozzle on Air-jet loom of reliable wefting insertion, new to this practicality below in conjunction with the accompanying drawings
Type is described in further detail.
As shown in Figure 1-2, a kind of Features of Auxiliary Nozzle on Air-jet loom of reliable wefting insertion, including shell 1, during the inside of shell 1 is
Air chamber, shell 1 include upright drosal part and nauropemeter sidepiece, and nauropemeter sidepiece tilts to upright drosal part, and the two converges shape
Into the vertex of a cone.Upper and lower two spray orifices 2,3 are provided with nauropemeter sidepiece, the cross sectional shape of two spray orifices is circular and two injection diameters
It is of different sizes.The upper diameter of spray orifice 2 is less than the diameter of lower spray orifice 3, and two spray orifices penetrate with internal middle air chamber.Upper spray orifice 2 it is straight
Footpath is 0.8-1mm, a diameter of 1.3-1.5mm of lower spray orifice 3, and the distance of center circle of upper and lower spray orifice is 1.8-2.0mm.Nauropemeter sidepiece
Inwall on poroelasticity film 4 is installed, multiple stomatas are evenly distributed with poroelasticity film 4, poroelasticity film 4 covers down
Spray orifice 3 is close to one end of middle air chamber.
Above-mentioned embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any to this practicality
Structure after new simple transformation belongs to the scope of protection of the utility model.
