Abstract
The utility model provides a pressure protection device for a producing well. The pressure protection device comprises an upper gland, an outer barrel, a pressure relief and liquid drainage hole, a flow discharge hole and a lower through hole, the upper gland is arranged at the top end of the outer barrel, the pressure relief and liquid drainage hole is formed in one side of the outer barrel, a fixed guide pipe and a movable guide pipe are arranged below the upper gland inside the outer barrel, and an upper valve and a lower valve are arranged below the movable guide pipe. The pressure protection device has the advantages that the problem that a pump and an oil pipe are damaged due to the fact that the pressure of a pipeline is too high when an oil conveying pipeline is blocked is effectively solved, and the service life of an oil well pump and the oil pipe is prolonged.
Description
Technical field
The utility model relates to a kind of oil production equipment, is specifically related to a kind of producing well pressure protective device.
Background technology
At present in oil well production process because the reasons such as petroleum pipeline oil is thick, wax deposition result in blockage, cause that pressure raises easily to cause downhole pump and pipeline rupture to damage, shorten down-hole pump and oil pipe application life.
Utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of producing well pressure protective device.
Technical solution adopted in the utility model is: a kind of producing well pressure protective device; comprise upper press cover, urceolus, pressure release outage, discharge orifice, lower through-hole; the top of urceolus is provided with upper press cover; one side of urceolus is provided with pressure release outage; below the upper press cover of the inside of urceolus, be provided with A/C and movable conduit, the below of movable conduit is provided with valve and lower valve.
In upper press cover, be provided with magnetic-inductive device.
A/C is socketed in movable conduit outside, and ring spring is around A/C and movable conduit periphery, and one end of movable conduit is provided with magnet.
Upper valve and lower valve connect together, and a side of upper valve is connected with pressure release outage, and upper valve and lower valve socket place are provided with rubber seal, and a side of lower valve is provided with discharge orifice, and lower valve bottom is provided with lower through-hole.
The beneficial effects of the utility model are: effectively solved the problem that causes pump and Tubing failure when petroleum pipeline stops up because pipeline pressure is too high, extended oil pump and oil pipe application life.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: anti-that on 1 upper press cover, 2 magnetic-inductive devices, 3 A/Cs, 4 springs, 5 magnet, 6 movable conduits, 7 urceolus, 8,9 pressure release outages, 10 rubber seal, 11 times valves, 12 discharge orifices, 13 lower through-holes.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure; a kind of producing well pressure protective device; comprise upper press cover 1, urceolus 7, pressure release outage 9, discharge orifice 12, lower through-hole 13; the top of urceolus 7 is provided with upper press cover 1; one side of urceolus 7 is provided with pressure release outage 9; below the inside of urceolus 7 upper press cover 1, be provided with A/C 3 and movable conduit 6, the below of movable conduit 6 is provided with valve 8 and lower valve 11.
In upper press cover 1, be provided with magnetic-inductive device 2.
A/C 3 is socketed in movable conduit 6 outsides, and spring 4 is looped around A/C 3 and movable conduit 6 peripheries, and one end of movable conduit 6 is provided with magnet 5.
Upper valve 8 connects together with lower valve 11, and a side of upper valve 8 is connected with pressure release outage 9, and upper valve 8 is provided with rubber seal 10 with lower valve 11 socket places, and a side of lower valve 11 is provided with discharge orifice 12, and lower valve 11 bottoms are provided with lower through-hole 13.
When use, this device is installed on to well mouth of oil well production tree resistance oil nozzle sleeve outside, pressure release outage 9 is connected with sleeve gate, in the time that oil well is normally produced, this device has better sealing and can stop oil and gas leakage, can confirm that these devices are in normal production status or overvoltage earial drainage state by top magnetic-inductive device 2 simultaneously.In the time that line clogging and down-hole pump are normally produced; manifold pressure progressively raises; in the time reaching setting value, in pipeline, press and promote to move on upper valve 8; drive on lower valve 11 and move; on move lower valve 11 after certain distance discharge orifice 12 be communicated with pressure release outage 9; by earth pressure release; realize the overvoltage protection to down-hole pump and oil pipe; simultaneously the magnet 5 at movable conduit 6 tops is to magnetic-inductive device 2 generation effects while moving certain distance upper, and magnetic-inductive device 2 is converted to overvoltage earial drainage state by the normal production status of instruction.
