Description
Technical field
The present invention relates to a kind of reciprocating pump hydraulic-end pump head body, especially a kind of reciprocating pump of suitable high oil field water injection
Fluid end alternating cavity is without intersection entire combination pump head body.
Background technology
At present, existing reciprocating pump hydraulic-end is largely all made of pump head body, packing box, intake manifold.Such as Fig. 1 institutes
Show, the liquid sucting valve 2 and tapping valve 1 wherein in the cylinder of pump head body configure for up/down steps formula, and the plunger (not shown) of pressurization hangs down
On straight 5 position of alternating cavity being arranged among liquid sucting valve 2 and tapping valve 1, therefore alternating cavity 5 and plunger in the cylinder of pump head body
Cross bore intersection is inevitably present between intersecting, and intersection angle has concentrated stress larger.When the pump is operated,
The pressure difference of high-voltage alternating intracavity liquid pressure is up to megapascal more than 40, and change per minute hundreds of times, in frequent alternating pressure
Under effect, the big position of pump head body stress easily cracks, and causes pump head body service life shorter.And due to suction
Manifold 4 is separately set with pump head body 3, and liquid sucting valve 2 and tapping valve 1 are the configuration of up/down steps formula, make its complicated, screw compared with
More, sealing is difficult, and dismounting maintenance is inconvenient, and manufacture cost is higher.
The content of the invention
The main object of the present invention provides one kind aiming at the deficiency of the prior art without intersection entire combination pump head
Body, its pump head body alternating cavity exist without intersection, extend the service life of pump head body.
The secondary objective of the present invention is to provide one kind without intersection entire combination pump head body, the high pressure liquid stream of its alternating cavity
Do not act directly on pump head body, further extend the service life of pump head body, and make its easy to maintenance.
Another object of the present invention is to provide one kind without intersection entire combination pump head body, its intake manifold and pump head body
One is set to, structure is simplified, eliminates the components such as packing box, and makes liquid stream uniform, inlet valve functioning equalization.
The purpose of the present invention is be achieved in that ground：A kind of reciprocating pump hydraulic-end alternating cavity is without intersection entire combination pump head
Body, it is made of pump head body, intake manifold, plunger and liquid sucting valve and tapping valve.Suction is vertically drilled with its pump head body
Hole, the horizontal through type combination valve comprising liquid sucting valve and tapping valve, it is arranged in the horizontal through type cylinder holes of pump head body, column
Plug connects with horizontal through type combination valve level.
The inlet hole can prolong pump head body and axially and symmetrically set two.
The horizontal through type combination valve is equipped with several suction inclined tubes, and the one end for sucking inclined tube is communicated with inlet hole, separately
One end is equipped with suction valve disc, another termination plunger of suction valve disc；Several discharge straight tubes are additionally provided with valve body, discharge straight tube one
End is communicated with the alternating cavity of horizontal through type combination valve, and the other end is equipped with discharge valve block, and the other end for discharging valve block is discharge
Hole.
Outer separator is equipped between the suction valve disc and plunger and pump head body.
The tap is arranged on the constant pressure intracavitary of outlet side supported flange, and outlet side supported flange, which closes, is screwed on pump
On head body, outlet side supported flange screws togather affixed with horizontal through type combination valve.
The outer separator can be flexible material.
Learn that of the invention is simple and reasonable, and the high pressure liquid stream of alternating cavity does not act on directly according to said structure analysis
On pump head body, the stress concentration of pump head body is eliminated, improves the stressing conditions of pump head body, extends the use of pump head body
Service life, and its manufacture, installation, maintenance are conveniently, cost is relatively low.
Brief description of the drawings
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the pump head body structure diagram of the prior art；
Fig. 2 is the front view of the present invention；
Fig. 3 is the A-A cross-sectional views of Fig. 2.
Specific implementation
Referring to Fig. 2,3, for the present invention without intersection entire combination pump head body, it is mainly vertically drilled with inlet hole on pump head body 6
7, and the horizontal through type combination valve 9 being arranged in the horizontal through type cylinder holes of pump head body 6 forms.That eliminate former with pumping
The intake manifold 4 that is separately set of head body 6, the greatly simplified structure of device.Inlet hole on pump head body 6 can prolong pump head body axis
To being symmetrical arranged two 7,7 '.So as to meet symmetrically to suck, coefficient of fullness is added, makes inlet valve functioning equalization.
Horizontal through type combination valve 8 includes liquid sucting valve and tapping valve, and plunger 9 connects with horizontal 9 level of through type combination valve.
Horizontal through type combination valve 8 is equipped with several suction inclined tubes 10, and one end of suction inclined tube 10 is communicated with inlet hole 7,7 ', the other end
Equipped with suction valve disc 11, another termination plunger 9 of suction valve disc 11；Several discharge straight tubes 12 are additionally provided with valve body 8, discharge is straight
12 one end of pipe is communicated with the alternating cavity 13 of horizontal through type combination valve 8, and the other end is equipped with discharge valve block 14, discharge valve block 14
The other end is tap 15.Tap 15 is arranged in the constant pressure chamber 17 of outlet side supported flange 16, outlet side supported flange 16
Close and be screwed on pump head body 6, outlet side supported flange 16 screws togather affixed with horizontal through type combination valve 8.
During inhalation, liquid is under the action of atmospheric pressure, from inlet hole 7,7 ' by sucking 10 open-top suction of inclined tube
Enter valve block 11, into alternating cavity 13.When plunger 9 starts to move back and forth, by the liquid in alternating cavity 13 by discharging straight tube
12, squeeze discharge valve block 14 and enter in the constant pressure chamber 17 of outlet side supported flange 16, then discharged from tap 15.Due to using
Horizontal through type combination valve 8 exists without the intersection of stress concentration, and the force-bearing situation of each component is greatly improved.Especially because
It is arranged on for alternating cavity 13 in valve body 8, the high pressure chest of outlet side is spaced with pump head body 6, and makes whole fluid pressure alternation
On the pump head body 6 that process and the discharge of last highly pressurised liquid do not act on directly, therefore extend the use longevity of pump head body 6
Life, reduces cost of goods manufactured, while dismounting, the installation of its each component are more convenient.Such as in maintenance, pull down discharge
Supported flange 16 is held, the horizontal through type combination valve 8 of easily taking-up can be handed over to be replaced, provided to daily maintenance work
It is convenient.
Furthermore outer separator 18 is equipped between suction valve disc 11 and plunger 9 and pump head body 6, outer separator 18 can be flexible
Material.So high pressure liquid stream is acted directly on outer separator 16, and is not acted on pump head body 6, improves the suction of pump head body 6
Enter the force-bearing situation at end, further extend 6 service life of pump head body.
