Jet can produce strong erosion to tool interior, and water jet be sprayed onto sleeve pipe backwash return tool exterior is produced serious
Destroy, serious result even in dropping of nozzle and pressure cap.Existing hydrajet tool typically can only carry out one and make twice
Industry, may result in tool failures, needs multiple replacing instrument just can complete the construction operation of a bite well.
Content of the invention
Present invention solves the technical problem that：Design a kind of high reliability hydraulic ejector, can effectively prevent high-speed water jet
The erosion that hydraulic ejector inside is produced, high-speed water jet backwash fall to the destruction outside hydraulic ejector and nozzle
Fall, greatly improve the construction hop count of hydrajet tool.
Technical scheme：A kind of high reliability hydraulic ejector, including body, described body is formed with pressure cap
Hole, nozzle is located in pressure cap, and pressure cap is fixed on pressure cap hole；It is formed with annular recess on the inwall of described body, and ring
Shape groove and the lower port insertion of body, bushing is inserted in annular recess from the lower port of body；Described body and bushing
Corresponding locating slot is all formed with lower surface, locating piece is inserted in locating slot and bushing is circumferentially located on body, makes bushing
On the jet orifice that has align with nozzle, and the internal diameter with diameter greater than nozzle of jet orifice is less than the external diameter of nozzle；Described body
Lower port on be connected with lower contact, and by the inner face of lower contact, locating piece is kept off in locating slot；Outside described pressure cap
Gland is fixed with end face.
Described pressure cap hole is in the little stepped ramp type of outer imperial palace, and its inner aperture is internal thread hole；Described pressure cap be in and pressure
The stepped ramp type that cap aperture matching form closes, and its endoporus is in outer little interior big stepped ramp type, nozzle is inserted in the macropore of the inner, outer end
Aperture be interior hexagon；The external screw thread that described pressure cap passes through have on its small end outer wall is arranged on the female thread at pressure cap in the hole end
Kong Zhong；Described gland is installed on the boss in pressure cap outer end central authorities, and the aperture just to pressure cap outer end for its centre bore.
Leave annular shoulder on described body at the inner face in pressure cap hole, and the centre bore of annular shoulder is just to jet
Hole.
Have the advantage that in the present invention and effect：
1st, the present invention, can be with effectively solving hydraulic ejector by arranging the bushing that special high-abrasive material is made and gland
The interior erosion occurring in oil gas field site operation and backwash problem, greatly improve the construction hop count of hydrajet tool.
2nd, the shoulder that the present invention passes through on body is combined with bushing, can effectively prevent dropping of nozzle, greatly improve
Dependability and the efficiency of construction.
Brief description
Fig. 1 is the structural representation of the present invention,
Fig. 2 is the partial enlargement structural representation of the present invention,
Fig. 3 is the A-A sectional view of Fig. 1.
Specific embodiment
A kind of embodiment of the present invention is described with reference to Fig. 1,2,3.
A kind of high reliability hydraulic ejector, including body 1, described body 1 is formed with pressure cap hole 2, described pressure cap hole 2 is in
The little stepped ramp type of outer imperial palace, and its inner aperture is internal thread hole；Pressure cap 4 is in the stepped ramp type closing with pressure cap hole 2 matching form,
And its endoporus is in outer little interior big stepped ramp type, nozzle 3 is inserted in the macropore of the inner, and the aperture of outer end is interior hexagon, is used for
The handling of pressure cap 4；The external screw thread that described pressure cap 4 passes through have on its small end outer wall is arranged on the internal thread hole of pressure cap hole 2 the inner
In；On the outer face of described pressure cap 4, soldering has gland 9, and gland 9 is installed on the boss in pressure cap 4 outer end central authorities, and makes wherein
The aperture just to pressure cap 4 outer end for the heart hole.
Annular recess 5, and the lower port insertion of annular recess 5 and body 1, bushing 11 are formed with the inwall of described body 1
It is inserted in annular recess 5 from the lower port of body 1；All it is formed with corresponding positioning on the lower surface of described body 1 and bushing 11
Groove 6, locating piece 7 is inserted in locating slot 6 and bushing 11 is circumferentially located on body 1, the jet orifice 8 making to have on bushing 11 with
Nozzle 3 aligns, and the internal diameter with diameter greater than nozzle 3 of jet orifice 8 is less than the external diameter of nozzle 3；Spiral shell in the lower port of described body 1
