Abstract
The present invention relates to a kind of shale gas pressure break ball valves, it is characterised in that：Including valve rod, valve body, sphere, valve seat and gland flange, the valve inner is equipped with cavity, the sphere is arranged in the cavity in valve body, the valve seat lateral circular sphere setting, the lateral position of fixed sphere, the both sides of the valve body are respectively equipped with gland flange, the gland flange is connected and fixed with valve body, the gland flange boring, and is connected to by ball for ball valve, the valve rod is inserted into valve body, and is connected and fixed with sphere upper end.Its advantageous effect generated is completely to press off to open torque only has flat gate valve 30% 40%, one, which can be completed completely to press off, opens work, can greatly reduce the labor intensity of operator.In addition, the use of shale gas pressure break ball valve of the present invention is split type, greatly reduce the cost of raw material, while also reducing processing cost, it can effectively, reasonably use each component, improve production efficiency, reduce production cost.
Description
Technical field
The present invention relates to shale gas exploitation field more particularly to a kind of shale gas pressure break ball valves.
Background technology
Oil and gas exploitation technology reaches its maturity at present, and for the oil gas field of low yield, low-permeability, low-porosity
For, then the yield that oil gas field is improved using fracturing technique is needed, and common oil and gas wellhead is improved by the methods of water filling
Oil-gas mining capability efficiency is low, but lacks corresponding effective method for the exploitation of shale gas.
Invention content
The purpose of the present invention is to provide a kind of reduction operator's labor intensity, carry efficient shale gas pressure break ball valve.
To achieve the above object, shale gas pressure break ball valve of the invention, it is characterised in that：Including valve rod, valve body, sphere,
Valve seat and gland flange, the valve inner are equipped with cavity, and the sphere is arranged in the cavity in valve body, and the valve seat is lateral
Be arranged around sphere, the lateral position of fixed sphere, the both sides of the valve body are respectively equipped with gland flange, the gland flange with
Valve body is connected and fixed, the gland flange boring, and is connected to by ball for ball valve, and the valve rod is inserted into valve body, and with
Sphere upper end is connected and fixed.
Further, the present apparatus further includes valve deck, and the valve deck is fixed on the top of valve body.
Further, the present apparatus further includes fixed seat and positioning pin, and the fixed seat is separately positioned on upper and lower the two of sphere
End, is fixed between the fixed seat and gland flange by positioning pin.
Preferably, the valve rod multidiameter structure, valve deck are positioned by valve rod step.
Preferably, it is bolted to connection between the gland flange and valve body.
Preferably, the valve stem end processes squarely, and compatible squared counter bore therewith is equipped in the sphere, described
Valve stem end coordinates with the squared counter bore in sphere.
The shale gas pressure break ball valve of the present invention expires to press off and opens the 30%-40% that torque only has flat gate valve, one can be complete
Work is opened at completely pressing off, the labor intensity of operator can be greatly reduced.In addition, the use of shale gas pressure break ball valve of the present invention
It is split type, greatly reduce the cost of raw material, while also reducing processing cost, it can effectively, reasonably use each portion
Part improves production efficiency, reduces production cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
In figure：1 is sphere, and 2 be valve body, and 3 be valve seat, and 4 be valve deck, and 5 be valve rod, and 6 be gland flange, and 7 be fixed seat, 8
It is positioning pin.
Specific implementation mode
Such as Fig. 1, shale gas pressure break ball valve of the invention, mainly by valve rod 5, valve body 2, sphere 1, gland flange 6, fixed seat
7 and positioning pin 8 form, wherein valve body 2 is internally provided with cavity compatible with 1 shape of sphere, and sphere 1 is arranged in valve body 2
In cavity, the setting of 3 lateral circular sphere 1 of valve seat, the lateral position of fixed sphere 1.The both sides of valve body 2 are respectively equipped with a gland
Flange 6 is connected and fixed between gland flange 6 and valve body 2 by fastening bolt.6 boring of gland flange, both sides gland flange
It is interconnected by the sphere of ball valve 1 between 6.
5 end of valve rod processes squarely, and compatible squared counter bore therewith, 5 end of the valve rod are equipped in the sphere 1
Coordinate with the squared counter bore in sphere 1, and is connected and fixed with 1 upper end of sphere.By rotary valve rod 5, to drive 1 edge of sphere
The common axis line rotation for sphere 1 and valve rod 5, realizes the on off state of valve.Valve rod 5 is multidiameter structure, and the setting of valve deck 4 exists
2 top of valve body, and positioned by 5 step of valve rod, it is connected and fixed by bolt and valve body 2.Distinguish in the upper/lower terminal of sphere 1
If there are one fixed seats 7, fixed by positioning pin 8 between fixed seat 7 and gland flange 6.
In actual use, sphere 1 is placed in 2 inner cavity of valve body the present invention, solid by upper and lower two fixed seats 7
It is fixed, it is connected by bolt with valve body 2 in two gland flanges 6 for being equipped with valve seat 3, fixed seat 7 passes through positioning pin 8 and pressure
The cooperation installation of lid flange 6,1 upper design of sphere have squared counter bore, 5 end of valve rod processing squarely to match with 1 squared counter bore of sphere
It closes, the switch shape of valve is realized to drive sphere 1 to be rotated along the common axis line of sphere 1 and valve rod 5 by rotary valve rod 5
State.Later stage suitable for low yield, low-permeability, low-porosity oil field exploits, and restores and improve the flow conductivity of oil reservoir, right
Enough flow conductivities can also be provided in the exploitation of shale gas.
Above-described specific implementation mode has carried out further the purpose of the present invention, technical solution and advantageous effect
It is described in detail, it should be understood that the foregoing is merely the specific implementation mode of the present invention, the guarantor being not intended to limit the present invention
Range is protected, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all be contained in this hair
Within bright protection domain.
