Description
Technical field
The utility model belongs to oil field hydraulic fracturing equipment technical field, is related to a kind of New Low Voltage valve body.
Background technology
The hydraulic fracturing of shale oil gas construction be a system oil-gas field development well stimulation, comprehensive geology, oil reservoir, technique
Technology many aspects, formed and be up in the gassiness purpose of horizon drilling well of 3000~4000 meters of underground under the guidance of geological reservoir in advance
1500 meters of horizontal straight well section, ground fracturing car assemble the pressure break pump truck of standby total water horse power 40,000 or so, by fracturing blender truck by fracturing fluid
Load fluid is formed with mixed with proppants, pressure break pump truck provides power resources by engine on platform, adds load fluid by fluid end
Pressure squeezes into high pressure pipe joint and well head, and then carries out making seam into shaft bottom.Fluid end is a kind of plunger reciprocating pump, typically by five cylinders or
The cylinder of person three is formed, and each cylinder body is made up of plunger, low-pressure end, high-pressure side, and part fluid end is additionally provided with maintenance overhaul window, takes sand
Liquid carries proppant and enters fluid end inner chamber by low-pressure end, moves and pressurizes through piston reciprocation, is discharged by high-pressure side.
Low pressure valve body is designed with the low-pressure end of each cylinder body of fluid end, it is different from the construction of conventional sandstone reservoir fracturing,
Shale oil gas hydraulic fracturing operational discharge capacity is big, and Construction Condition is complicated, and low pressure valve body bears to take for a long time in work progress
The abrasion of sand liquid high speed waterpower, erosion, the abrasion strength resistance of valve body, which turns into, restricts whether construction can be normally carried out and safety is entered
Capable key influence factor.The low pressure valve body of prior art has following defect.
(1) low pressure valve body form construction design used in the country is typically born using four paws leading truck front at present
The impact of load fluid, often occurs leading truck wear and rupture phenomenon, and post-rift leading truck is right under the drive of high speed load fluid
Fluid end body, which produces strength abrasion, causes fluid end to be damaged, the personnel of serious threat job site, equipment safety.
(2) the rubber sealing ring sealing effectiveness of low pressure valve body is poor, not only influences valve body load performance, has an effect on
Construction safety various aspects.
(3) body of low pressure valve body and guide way cast processing respectively, and then welding assembly is to together, service life
Short, the concentricity of body and guide way is difficult to ensure that, often aggravates the abrasion of valve body body.
(4) low pressure valve body service life is short, and replacing frequently results in that construction cost is costly, labor intensity is big, exists at present
In shale oil gas staged fracturing of horizontal well work progress, the preferable low pressure valve body of quality is typically changed once using 6~8 sections,
Poor 2~3 sections needs are changed individually.
The content of the invention
The purpose of this utility model is to provide a kind of fracturing unit truck New Low Voltage valve, the defects of to overcome prior art.
The purpose of this utility model is achieved through the following technical solutions.
Fracturing unit truck New Low Voltage valve, including rotary body, guide rod and sealing ring, it is characterised in that rotary body is by revolving
Turn bottom surface, round platform rank and inner concave to form, the guide rod is located at rotary body bottom surface and with rotating body by integral forming.Guide rod
Design no longer directly bears the erosive wear of load fluid in the bottom surface of rotary body, eliminate Damage and Fracture due to guide way and
The potential potential safety hazard for causing fluid end to damage.
Further, the sealing ring is made up of sealing ring body and sealing ring contact surface, sealing ring body and rotary body
Bottom surface fastening is connected.Arc surface of the sealing ring contact surface with fluid end low pressure valve seat metal body in work progress connects repeatedly
Touch and bear key wear and pressure, load fluid enters fluid end by the gap between sealing ring and low pressure valve seat.
Further, the rotary body and guide rod are formed by high-carbon alloy steel solid forging.Guide rod and rotary body are whole
Body forging molding, bonding strength is big, and concentric rate is high, and wear resistance is stronger.
Further, the sealing ring is made up of polyurethane material.The service life of low pressure valve body and making for sealing ring
It is closely related with the life-span, sealing ring is made using impact resistance, pressure-resistant, corrosion resistant polyurethane material, and wear resistance is stronger, this
The service life of sample valve body extends, and changing number and construction cost reduces.
The utility model can mainly obtain following beneficial effect：
(1) service life of low pressure valve body and the service life of sealing ring are closely related, sealing ring using impact resistance,
Pressure-resistant, corrosion resistant polyurethane material makes, and wear resistance is stronger, and the service life of such valve body extends, and changes number
Reduced with construction cost.
(3) guide rod and rotary body solid forging, bonding strength is big, and concentric rate is high, and wear resistance is stronger.
(4) the stock design of guide rod can bear for a long time fluid power erosion repeatedly and be less likely to be damaged or be broken, from
And reduce due to the damage of guide rod and cause the accident probability of this bulk damage of fluid end.
(5) the round platform rank of rotary body and inner concave design can effectively reduce load fluid in rotary body body and rotation
Erosive wear between body and stripper rubber contact surface.
