Abstract

The utility model relates to an oil and gas pipeline leaking stoppage and pressure discharging device. The oil and gas pipeline leaking stoppage and pressure discharging device comprises a leaking stoppage clamp and is characterized in that the leaking stopping clamp is an arc-shaped clamp with the radian larger than the radian of a semicircular arc, one end of the arc-shaped clamp is provided with an arc-shaped end cap with an L-shaped pressure discharging hole, a small threaded hole which penetrates through the L-shaped pressure discharging hole is formed in the arc-shaped end cap, and the other end of the arc-shaped clamp is provided with at least one threaded hole. The oil and gas pipeline leaking stoppage and pressure discharging device has the advantages that the oil and gas pipeline leaking stoppage and pressure discharging device is simple in structure, convenient to use and easy to detach, the arc-shaped clamp can be fixed to a pipeline through a bolt, opening and closing of the pressure discharging hole are controlled through a small bolt, the difference between pressure inside the pipeline and pressure outside the pipeline can be effectively lowered, downtime is greatly shortened, and production efficiency is improved.

Description

Oil-gas pipeline leak stopping pressure discharge device
Technical field
The utility model relates to the auxiliary device in field of petroleum exploitation, specifically relates to a kind of oil-gas pipeline leak stopping pressure discharge device.
Background technique
There is leak point in oil-gas pipeline; not only can reduce crude output, and easily cause large-area pollution, prior art is after shutdown; stamp clamp; to relevant department's application, leak source is carried out to soldering, existing clamp is all to connect two cards with bolt, and the installation time is longer; and can only leak stopping; effectively row pressure, adds the loaded down with trivial details requisition procedure of getting angry, and has had a strong impact on the raising of oil extraction efficiency.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, develops a kind of oil-gas pipeline leak stopping pressure discharge device, solves the excessive leak stopping difficult problem causing of oil-gas pipeline internal pressure.
Its technological scheme is: comprise leak stoppage checkpost, it is characterized in that: described leak stoppage checkpost is the arc clamp that is greater than semicircle radian, arc clamp one end arranges the arc plug that has L shaped pressure releasing hole, minor thread hole through L shaped pressure releasing hole is set in arc plug, L shaped pressure releasing hole end arranges outlet, the arc clamp the other end arranges at least one tapped hole, by bolt, arc clamp is fixed on pipeline.
Described arc plug inner side arranges rubber sealing gasket.
The diameter that described L shaped pressure releasing hole approaches pipeline leakage point place is greater than the diameter in its outlet port.
Beneficial effect
This model utility is simple in structure, easy to use, is easy to dismounting; by bolt, arc clamp can be fixed on pipeline, rely on stove bolt to control the switch of pressure releasing hole, can effectively reduce the inside and outside pressure reduction of pipeline; greatly shorten dead time, improved manufacturing efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present embodiment.
Embodiment
Below in conjunction with accompanying drawing 1, be further described: a kind of pipeline blockage pressure discharge device, comprise leak stoppage checkpost, described leak stoppage checkpost is the arc clamp 8 that is greater than semicircle radian, one end of arc clamp 8 arranges the arc plug 5 that has L shaped pressure releasing hole 9, the interior setting of arc plug 5 is through the minor thread hole of L shaped pressure releasing hole 9, coordinate with stove bolt 3, the end of L shaped pressure releasing hole 9 arranges outlet 2, the other end of arc clamp 8 arranges at least one tapped hole, by bolt 7, arc clamp 8 is fixed on described pipeline 6, the inner side of arc plug 5 arranges rubber sealing gasket 1, L shaped pressure releasing hole 9 approaches pipeline leakage and puts the diameter that the diameter at 4 places is greater than outlet 2 places of L shaped pressure releasing hole 9.
