Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the description of one step is done to the utility model:
Embodiment one
As shown in Fig. 4 and Fig. 1, jet pipe is revolving body, the entirety be made up of outer tube 1 and nozzle 2.Whole jet pipe comprises outer wall 3 and inwall 4, is solid cemented carbide body between outer wall 3 and inwall 4, what inwall 4 surrounded is one different, but be interconnected cavity.Cavity is made up of input cavity 11, contraction chamber 12 and spray chamber 21, and the central axis of input cavity 11, contraction chamber 12 and spray chamber 21 on the same line.
As shown in figures 1 and 3, the outer wall 3 of outer tube 1 surrounds one cylindric and one round table-like, and input cavity 11 and contraction chamber 12 are all wrapped in outer tube 1.Liquid flows fast from input cavity 11 to spray chamber 21 direction in jet pipe.Connection between input cavity 11 and contraction chamber 12 is in smoothing junction, and input cavity 11 is columned cavitys, and its diameter is the preferred value of D3, D3 is 15mm-18mm.
As shown in Figures 2 and 3, contraction chamber 12 is rotational-like, and its bus is one section of level and smooth curve.Be protrude laterally or cave in the inside by the shape of bus, bus be divided into outwardly projecting portion 121 and concave section 122.The major part of bus is the concave section 122 of caving in the inside, in smoothing junction in order to ensure contraction chamber 12 and input cavity 11, and bus has a bit of outwardly projecting portion 121 for protruding laterally.
The outwardly projecting portion 121 of bus and concave section 122 are all circular arc lines, and the diameter of outwardly projecting portion 121 circular arc line is that the value of D1, D1 is identical with the value of the diameter D3 of input cavity 11.Bus due to contraction chamber 12 caves in the inside and is conducive to concentrating of liquid, and not easily scatter after ejection, therefore in the present embodiment, the bus of one end that contraction chamber 12 and spray chamber 21 limit connect is the concave section 122 of caving in the inside.
In addition, the diameter of concave section 122 circular arc line of contraction chamber 12 is larger, and the change of the bus of contraction chamber 12 is milder, is more conducive to concentrating of liquid.But the diameter of concave section 122 circular arc line is larger, the length of contraction chamber 12 also can be larger, can increase the cost of manufacture.The length of contraction chamber 12 is the preferred value of L1, L1 is 22mm-28mm, and the diameter of concave section 122 circular arc line is the preferred value of D2, D2 is 65mm-75mm.
As shown in Figure 3 and Figure 4, nozzle 2 is hollow tubular body, and the cavity that the inwall 4 of nozzle 2 surrounds is spray chamber 21.Current liquid jet is not with nozzle 2, is only made up of outer tube 1, and the concave section 122 of also not caving in the inside in contraction chamber 12.The liquid that these structures all make current liquid jet spray easily scatters.Spray chamber 21 is cylindric, has certain length, can make the ejection that liquid is more concentrated.The length of spray chamber 21 is the preferable range of L2, L2 is large 5mm.And the ratio of the value of the diameter of the value of the diameter of input cavity 11 and spray chamber 21, can have a great impact the speed of liquid ejection.The diameter of spray chamber 21 is the preferred value of D4, D4 is 1.5mm-3mm.
In sum, the utility model is by input cavity 11, adopts smooth connection between contraction chamber 12 and spray chamber 21; The concave section 122 for caving in the inside of one end that contraction chamber 12 is connected with spray chamber 21, and the diameter of concave section 122 is comparatively large, transition is milder; And the circular tube shaped nozzle 2 being connected with certain length on outer tube 1 makes the liquid sprayed not easily scatter.
Obviously, under the prerequisite not departing from principle described in the utility model, the some improvement made or modification all should be considered as protection domain of the present utility model.
