Description
Technical field
The utility model relates to the manufacturing technology fields of industrial gas oil underground work equipment, specifically relate to one
Kind fracturing pump valve body, for well production increment pressure break fracturing pump.
Background technique
As the scale of shale gas is exploited, shale gas well hardware and software platform operation is more with construction layer position, discharge capacity is big, single layer construction
The big feature of liquid measure, the previous platform of mesh need 20 or so fracturing unit trucks while constructing.Fracturing pump is the core of fracturing unit truck
Part, fracturing pump valve body are groundwork elements in the pump housing, and cooperation valve seat uses, and control suction side and discharge in fracturing pump
The unlatching and closure at end realize that low-pressure fluid is converted to high-pressure fluid discharge by fracturing pump.
In current underground fracture acidizing treatment, the valve component that fracturing pump uses on fracturing unit truck mainly has straight-bar type valve body
With claw valve body.
Straight-bar type valve body adds accurate guide rod up and down and dedicated centralizing bracket and valve seat pallet is cooperated to use, can
Guarantee valve body rubber being accurately located at valve seat center in each sealing function, so that sealing and suction effect all reach
To best, but due to being mounted with pallet below valve seat, cause valve seat removal tool be difficult to put forth effort on valve seat to its into
Row is removed, and brings quite big difficulty to the fast pace construction of present shale gas exploitation.
Claw valve body is oriented to mainly by the guide grab of lower part, due to not set guide rod, does not need installation pallet,
Valve seat can be removed with valve seat removal tool easily when damaging.But also due to not set guide rod, valve body is in pump chamber
In easy double swerve, lead to the poor sealing effect of valve body rubber, it is inadequate to the extracting force of load fluid, in the shale of huge discharge
Empty pump is often walked when gas sand fracturing.
It is big and steady that both fracturing pump valve bodies all cannot perfectly meet discharge capacity required for present shale gas exploitation very much
It is fixed, the fast requirement of speed of application.
Publication No. 203321812U, publication date are that the Chinese patent literature on December 4th, 2013 discloses a kind of plunger
Valve body, including valve ontology are pumped, which is coaxially formed with a sucking valve cavity and discharge valve respectively
Cavity corresponds to and is separately installed with sucking valve and discharge valve, the valve body end in discharge valve side in two cavitys
Coaxially connected righting shell is co-axially mounted a cylindrical sleeve between the sucking valve, discharge valve and valve ontology respectively.This
Valve body is effectively mentioned by being co-axially mounted a cylindrical sleeve with higher hardness in sucking valve cavity and discharge valve cavity
The wear-resisting property of high valve body, so that its service life is improved, in addition, cylindrical sleeve is only needed to change after the abrasion of valve body,
Maintenance cost is reduced, the outer rim of the cylindrical sleeve is a circular conical surface, it is convenient for disassembly and assembly, save maintenance time.
But using above patent document as the prior art of representative, it is not particularly suited for fracturing pump.
Summary of the invention
The utility model is intended to provide a kind of fracturing pump valve for defect and deficiency present in the above-mentioned prior art
Body can effectively solve the mating valve seat of valve body in the presence of the prior art and be difficult to remove and all using the utility model
Your body rubber such as cannot effectively seal at the technical problems.
The utility model is realized by using following technical proposals:
A kind of fracturing pump valve body, it is characterised in that: mainly by centralizing bracket, spring, guide rod, rubber occlusion disk, guiding
Pawl and valve seat composition, the guide rod and guide grab are connected to the upper and lower side of rubber occlusion disk, the guide rod
It is coupled by spring and centralizing bracket, the guide grab is coupled with valve seat.
The rubber occlusion disk includes deep bid and shallow bid, is connected as one between deep bid and shallow bid;Rubber occlusion disk is set
It is equipped with double chamfering structures;Double chamfering structures refer to is equipped with filleted transition between deep bid and shallow bid, solid with guide grab
Fixed shallow bid end is provided with filleted transition.
There are three L-type pawl feet for the guide grab setting.
Compared with prior art, the utility model is achieved has the beneficial effect that:
1, in the utility model, using " guide rod and guide grab is connected to rubber occlusion disk upper and lower side, institute
The guide rod stated is coupled by spring and centralizing bracket, and the described rubber occlusion disk is provided with double chamfering structures " such knot
Configuration formula so that its overall structure is simpler, and has better guidance capability and leakproofness.
2, the utility model uses guide rod and the dual guide frame of guide grab, and valve physical efficiency is made to be accurately located at valve seat
Center, it is ensured that sealing effect and extracting force do not weaken.
3, rubber occlusion disk makes rubber be easier to be bonded with rubber occlusion disk, more conducively valve body glue using double chamfering structures
The sealing of skin and valve seat.
4, three L-type pawl feet are arranged in guide grab, more stable can be oriented to valve body, prevent valve body in pump chamber
Double swerve.
5, the installation of straight-bar type valve body pump chamber inner pallet is omitted, the valve seat of damage is easily quickly torn open
It removes.
6, compared with existing straight-bar type valve body and claw valve body, the utility model has higher bearing capacity and energy
High flow rate operation, and adapt to the multi-party planar due to appearance such as construction liquid quality, haydite clean level, practical feed flow situations
Condition improves fracturing unit truck in the service efficiency of platform well, accelerates shale gas construction speed.
