Description
Technical field
The utility model belongs to oil field hydraulic fracturing equipment technical field, is related to a kind of novel high-pressure 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, high-pressure side is designed with high pressure valve body, and normal
It is different to advise sandstone reservoir pressing crack construction, shale oil gas hydraulic fracturing operational discharge capacity is big, pressure is high, and high pressure valve body is in work progress
In bear prolonged load fluid high pressure, the abrasion of high speed waterpower, erosion, the abrasion strength resistance of high pressure valve body, which turns into restrict, constructs
The key influence factor that whether can be normally carried out and carry out safely.Following defect be present in the high pressure valve body of prior art.
(1) high 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, leading truck wear and rupture phenomenon often occurs, post-rift leading truck is in high pressure, the drive of high speed load fluid
Under to fluid end body produce strength abrasion cause fluid end to be damaged, the personnel of serious threat job site, equipment safety.
(2) the rubber sealing ring sealing effectiveness of high pressure valve body is poor, not only influences valve body load performance, has an effect on
Construction safety various aspects.
(3) body of high 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) high 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 high pressure valve body of quality is typically changed once using 7~10 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 novel high-pressure valve, the defects of to overcome prior art.
The purpose of this utility model is achieved through the following technical solutions.
Fracturing unit truck novel high-pressure valve, including rotary body, guide rod and sealing ring, it is characterised in that the rotary body
It is made up of one-level round platform rank, two level round platform rank, rounded corner, lower plane and inner concave, the guide rod is located at rotary body bottom surface simultaneously
With rotating body by integral forming.Rotary body is designed with two-stage step face, and the situation of load fluid erosion is directly being born in two-stage step face
Under, wear-resistant effect is more preferable.The lower plane of rotary body is transitioned into rotary body and sealing ring junction design rounded corner, is advantageous to
Sealing ring is in close contact with rotary body.Guide rod designs the erosive wear in the bottom surface of rotary body, no longer directly bearing load fluid,
Eliminate the potential potential safety hazard for causing fluid end to damage due to the Damage and Fracture of guide way.
Further, the sealing ring is made up of sealing ring body and sealing ring chamfering, sealing ring upper surface and rotary body
Two level round platform rank is connected.Sealing ring is tightly fixed on rotary body, in work progress with fluid end high pressure valve seat metal sheet
The arc surface of body contacts and bears key wear and pressure repeatedly, and load fluid passes through the gap between sealing ring and high pressure valve seat
High pressure pipe joint and well head are escaped and enter from fluid end.
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 high pressure valve body and making for sealing ring
Closely coupled 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 high pressure valve body extends, and changing number and construction cost reduces.
The utility model can mainly obtain following beneficial effect：
(1) guide rod design no longer directly bears the erosive wear of load fluid in the bottom surface of rotary body, eliminate due to
The Damage and Fracture of guide way and cause fluid end damage potential potential safety hazard.
(2) service life of high pressure valve body and the service life of sealing ring are closely coupled, sealing ring using impact resistance,
Pressure-resistant, corrosion resistant polyurethane material makes, and wear resistance is stronger, and the service life of such high pressure valve body extends, and changes
Number and construction cost reduce.
(3) guide rod and rotary body solid forging, bonding strength is big, and concentric rate is high, and wear resistance is stronger.
(4) rotary body is designed with two-stage step face, and two-stage step face is resistance in the case where directly bearing load fluid erosion
Abrasive effect is more preferable.
