Abstract
The utility model belongs to water pump technology, more particularly to a kind of jet pump nozzle, including nozzle body, perforative inner hole is arranged in nozzle body, the inner hole is made of the conical section and cylindrical portion being coaxially disposed, conical section extands rearward to nozzle body tail end face, and cylindrical portion extends forwardly into nozzle body front end face；Conical section small end and cylindrical portion are isometrical, and taper segment length is greater than cylindrical portion.Jet pump nozzle provided by the utility model reduces fluid resistance, improves the self-priming performance of water pump by setting cylindrical portion and conical section.
Description
Technical field
The utility model belongs to water pump technology, and in particular to a kind of jet pump nozzle.
Background technique
As shown in Fig. 4, existing nozzle bore is usually globoidal structure, and self-priming performance usually exists when cooperating with jet pipe
There is 9 meters of self-priming in 3 minutes, suction capacity is still to be improved.
Utility model content
The purpose of the utility model is to provide a kind of jet pump nozzles to reduce stream by setting cylindrical portion and conical section
Body resistance improves the self-priming performance of water pump.
Purpose of the utility model is realized as follows: a kind of jet pump nozzle, including nozzle body, nozzle body setting
Perforative inner hole, the inner hole are made of the conical section and cylindrical portion being coaxially disposed, and conical section extands rearward to nozzle body tail
End surface, cylindrical portion extend forwardly into nozzle body front end face；Conical section small end and cylindrical portion are isometrical, and taper segment length is greater than column
Shape section.
Further, the conical section outside diameter is 25mm, and cylindrical portion diameter is 9.5mm, nozzle body tail portion outer diameter
For 29mm, nozzle body head outer diameter is 12mm.
Further, the nozzle body outer wall is provided with first annular protrusion and the second annular protrusion, two convex annulars
Seal groove is formed between rising.
Further, the nozzle body head outer wall arc concave shape and diameter gradually narrows.
Further, the nozzle body periphery is provided with salient point, and salient point is located under the arc outer wall on nozzle body head
Side.
Further, there are four the salient point circumference uniform distributions.
Compared with the prior art, the utility model has prominent and beneficial technical effects that:
It is 9.5 millimeters that this programme, which increases cylindrical portion internal diameter, extends cylindricality segment length, maximum is expanded to 25 millimeters simultaneously
And become the straight conical surface, the creative self-priming performance for improving water pump, can in 1 minute 9 meters of self-priming, have 9.8 in 3 minutes
The self-priming of rice.

Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
A kind of jet pump nozzle includes combined with Figure 1 and Figure 2, nozzle body 1, and perforative inner hole is arranged in nozzle body 1, interior
Hole is made of the conical section 6 and cylindrical portion 7 being coaxially disposed, and conical section 6 extands rearward to 1 tail end face of nozzle body, cylindrical portion 7
Extend forwardly into 1 front end face of nozzle body；6 small end of conical section and cylindrical portion 7 are isometrical, and 6 length of conical section is greater than cylindrical portion 7.Spray
1 total length of mouth ontology is 33mm, and cylindrical portion 7 is extended for 7mm, wherein 6 outside diameter of conical section is 25mm, and 7 diameter of cylindrical portion is
9.5mm, 1 tail portion outer diameter of nozzle body are 29mm, and 1 head outer diameter of nozzle body is 12mm.
Specifically, 1 outer wall of nozzle body is provided with first annular raised 2 and second annular protrusion 3, two annular protrusions it
Between formed seal groove 4.First annular raised 2 lower end surface flushes setting with 1 bottom end face of nozzle body.
In conjunction with Fig. 3 it is found that 1 head outer wall arc concave shape of nozzle body and diameter gradually narrows, in order to match with jet pipe 8
It closes.
In order to the better immovable fitting of jet pipe 8,1 periphery of nozzle body is provided with salient point 5, and salient point 5 is located at nozzle body 1
Below the arc outer wall on head.There are four the preferred circumference uniform distributions of salient point 5.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
