Abstract
The utility model relates to a pressure tapping and measuring device of an oil-water well, which mainly solves the problem that the traditional well head pressure tapping device is easy to leak. The pressure tapping and measuring device is characterized in that bench holes (3) are arranged in the axial direction in a main body (1); a long neck straight through piston (4) is arranged in the bench hole (3) at the lower end of the main body; the upper end of the long neck straight through piston (4) is provided with an annular boss (7); a seal ring is arranged in a bottom outer annular groove; a pressure spring (5) is arranged in the bench hole (3) at the upper end of the long neck straight through piston (4); and the upper end of the pressure spring (5) is provided with a spring cap (6) connected with the bench holes (3). The pressure tapping and measuring device of the oil-water well does not leak under a high pressure state and has the characteristics of simple structure and low cost.
Description
Technical field:
The utility model relates to oil recovery field, oil field well head used pressure obtaning device, especially oil-water well pressure manometer.
Background technology:
In oil recovery field, oil field, go out hydraulic coupling in order to obtain well head, need pressure obtaning device be installed at well head.And having the well head pressure obtaning device now because reasons in structure exists the problem of easy to leak, contaminated environment influences the management of well head.
The utility model content:
The problem of easy to leak in order to solve existing well head pressure obtaning device.The utility model provides a kind of oil-water well pressure manometer.This oil-water well pressure manometer has no seepage and no leakage under high pressure conditions, the simple in structure and low characteristics of cost.
The technical solution of the utility model is: this oil-water well pressure manometer comprises the main body that has threaded upper end to be connected with the pressure meter short circuit outside the bottom.Step hole is axially arranged in the main body, the lower end step hole is built-in with the straight-through piston of long-neck, and there is annular boss the straight-through piston of long-neck upper end, in the outer ring groove of bottom sealing ring is arranged, in the step hole of the straight-through piston of long-neck upper end stage clip is arranged, there is the spring cap that links to each other with step hole the stage clip upper end.
The utlity model has following beneficial effect: this oil-water well pressure manometer is at first because employing is built-in with the straight-through piston of long-neck at main body lower axial end step hole, there is annular boss the straight-through piston of long-neck upper end, in the outer ring groove of bottom sealing ring is arranged, in the step hole of the straight-through piston of long-neck upper end stage clip is arranged, there is the spring cap simple structure that links to each other with step hole the stage clip upper end.Utilize the straight-through piston of long-neck to move up and down, solve the easy to leak problem, no seepage and no leakage under the high pressure conditions, and also simple in structure, processing cost is low.This oil-water well pressure manometer has no seepage and no leakage under high pressure conditions thus, the simple in structure and low characteristics of cost.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-main body among the figure, 2-pressure meter short circuit, the 3-step hole, the 4-long-neck leads directly to piston, 5-stage clip, 6-spring cap, 7-annular boss.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this oil-water well pressure manometer comprises the main body 1 that has threaded upper end to be connected with pressure meter short circuit 2 outside the bottom.Main body 1 is cylindrical, and screw thread is arranged outside the bottom, links to each other with oil-water well pressure manometer seat on the well head by screw thread, and the upper end is connected with pressure meter short circuit 2, is connected with pressure meter by pressure meter short circuit 2.The step hole 3 that secondary is axially arranged in the main body 1, the step hole 3 of lower end is built-in with the straight-through piston 4 of long-neck, the straight-through piston 4 of long-neck can move up and down in the step hole 3 of lower end, there is annular boss 7 straight-through piston 4 upper ends of long-neck, and be sitting on subordinate's stage, prevent that by annular boss 7 the straight-through piston 4 of long-neck from shifting out in step hole 3, in the outer ring groove of bottom sealing ring is arranged, sealing ring seals.In the straight-through piston 4 upper end step holes 3 of long-neck stage clip 5 is arranged, there is spring cap 6 stage clip 5 upper ends, and spring cap 6 limits stage clip 5 by screw thread and 3 interior linking to each other of step hole by spring cap 6, when pressure does not reach, promotes straight-through piston 4 returns of long-necks by stage clip 5.
During actual the use:
At first, pressure meter is connected on the main body 1 by pressure meter short circuit 2, main body 1 is being threaded on the well head on the oil-water well pressure manometer seat by the bottom again.Promote to move on the straight-through piston 4 of long-neck by well liquid, well liquid enters realizes pressure pressure measurement purpose in the pressure meter, solve the easy to leak problem.
This oil-water well pressure manometer has been obtained remarkable result by The field.
