Abstract
The utility model discloses an internal blowout preventer automatic pressure test device which comprises an inner blowout preventer and a pressure test plug and also comprises a hydraulic cylinder, a clamping centering mechanism and an injection compression flange. The inner blowout preventer matches the pressure test plug and the injection compression flange. The rear end of the inner blowout preventer is provided with the hydraulic cylinder. The front end of the inner blowout preventer is provided with the clamping centering mechanism which contains a cylinder and upper and lower four-bar linkage mechanisms. The cylinder drives the upper and lower four-bar linkage mechanism to move. The upper and lower four-bar linkage mechanisms are respectively provided with upper and lower roller rows. The pressure test plug is provided with two O-shaped sealing rings. The middle part of the pressure test plug is provided with an injection compression inlet which respectively matches the inner blowout preventer and the injection compression flange. By the adoption of the device provided by the utility model, the device provided by the utility model supports the assembly line work during the whole course. According to the utility model, automatic remote operation can be realized, and pressure test safety is guaranteed. Hydraulic top-tightening sealing is adopted and has higher reliability than manual thread sealing. In comparison with traditional pressure test, there is no need to replace heavy pressure test connectors in the device. Only the light pressure test plug needs to be replaced. In addition, there is no need to disassemble pressure test pipelines repeatedly. Feeding and blanking and sealing time is short; efficiency is high; manpower is saved; and labor intensity is raised.
Description
Technical field
The utility model relates to oil well control equipment Inspection pressure testing device, especially a kind of pressure-detecting device of interior jet-preventing tool.
Background technology
Along with the development of drilling technique and well control technology, interior jet-preventing tool is also day by day frequent in the application at wellbore construction scene.Interior jet-preventing tool comprises stopcock, flechette-type back pressure valve, ball-and-seat etc., is jet-preventing tool in a kind of drill string.Raising along with well control technical requirement, interior jet-preventing tool detection level and efficiency are in urgent need to be improved, yet because interior jet-preventing tool model and button-type is numerous and pressure test pressure is the highest can be up to 105MPa, therefore traditional interior jet-preventing tool pressure testing detection method often needs the pressure testing connector of 20-30 kind heaviness, is threaded connection and makes O-ring seal and interior jet-preventing tool butt-end packing in pressure testing process.So greatly affect pressure testing efficiency, increase workman's labour intensity, there is certain risk simultaneously.
Utility model content
The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, and provide a kind of, can operate, seal the interior jet-preventing tool automatic pressure testing device more reliable, pressure testing security performance is higher by automation remote.
The utility model is taked following technical measures: interior jet-preventing tool automatic pressure testing device, comprise interior jet-preventing tool, pressure testing plug, also comprise hydraulic cylinder, clamp mechanism placed in the middle, injection molding is blue, described interior jet-preventing tool matches with pressure testing plug, injection molding orchid, rear end at interior jet-preventing tool is provided with hydraulic cylinder, front end at interior jet-preventing tool is provided with clamping mechanism placed in the middle, clamp mechanism placed in the middle and comprise cylinder and upper and lower four connection-rod linkage mechanisms, the upper and lower four connection-rod linkage mechanism actions of air cylinder driven, are separately installed with the row of rolling up and down in upper and lower four connection-rod linkage mechanisms.
Described pressure testing plug is provided with twice " O " RunddichtringO, and pressure test plug centriciput is provided with to note and is pressed into mouth, matches respectively with interior blowout prevention pressure test instrument, injection molding orchid.
The beneficial effects of the utility model are: whole process can pipelining, has realized automation remote operation, guarantee pressure testing security; Adopt hydraulic top tightening seal, compare manual thread seal reliability higher; Compare and needn't change heavy action pressure-testing joint with traditional pressure testing, only need to change light pressure testing plug, and need not dismantle back and forth pressure testing pipeline; Loading and unloading, sealing time are short, and efficiency is high, save manpower, have improved labour intensity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model pressure testing plug sealed structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, interior jet-preventing tool automatic pressure testing device, comprise interior jet-preventing tool 1, pressure testing plug 2, also comprise hydraulic cylinder 3, clamp mechanism placed in the middle, injection molding orchid 4, described interior jet-preventing tool 1 and pressure testing plug 2, injection molding orchid 4 is matched, rear end at interior jet-preventing tool 1 is mounted with hydraulic cylinder 3 by flange, front end at interior jet-preventing tool 1 is provided with clamping mechanism placed in the middle, clamp mechanism placed in the middle and comprise cylinder 5 and upper and lower four connection-rod linkage mechanisms 6, cylinder 5 drives 6 actions of upper and lower four connection-rod linkage mechanisms, in upper and lower four connection-rod linkage mechanisms 6, be separately installed with the row of rolling 7 and under the row of rolling 8.
Described pressure testing plug 2 is provided with twice " O " RunddichtringO 9, and pressure testing plug 2 middle parts are provided with to note and are pressed into mouth 10, match respectively with interior blowout prevention pressure test instrument 1, injection molding orchid 4.
The course of work of the present utility model is, first by stock shelf handle, treat that the interior jet-preventing tool 1 of pressure testing is rolled into down in the row of rolling 8, put on the pressure testing plug 2 matching with it, now cylinder 5 is started working, drive the motion of four connection-rod linkage mechanisms 6, above the row of rolling 7 and under the oblique central motion of the row's of rolling 8 generation.When on the row of rolling 7 while touching interior jet-preventing tool 1, cylinder 5 motions stop, now in jet-preventing tool 1 be subject to the clamping force of the row of rolling up and down, and in clamping center condition.Then hydraulic cylinder 3 is started working, hydraulic mandril 11 will treat that in pressure testing, jet-preventing tool 1 is pushed injection molding orchid 4 to, make the accurate laminating of blue 4 threes of male thread front end face, pressure testing plug 2, injection molding of interior jet-preventing tool 1, under the effect of hydraulic cylinder push rod 11, make " O " in pressure testing plug 2 thus sealing function is played in RunddichtringO 9 distortion.From the water inlet of injection molding orchid 4, start to suppress, stop after reaching the rated pressure value of interior jet-preventing tool 1.In in whole pressure testing process, jet-preventing tool 1 and pressure testing plug 2 are subject to the acting force of Water Pressure power and hydraulic cylinder push rod 11, and the hydraulic pressure pressure of hydraulic cylinder 3 is greater than Water Pressure power.After pressure testing completes, hydraulic cylinder 3 shrinks hydraulic cylinder push rod 11, and cylinder 5 push rods also shrink, and drive four connection-rod linkage mechanism kinematics 6 to get back to original state.Interior jet-preventing tool 1 after pressure testing is completed rolls after blanking rack and takes off pressure testing plug 2, completes whole work pressure test flow process.
The utility model is not limited to above embodiment, and every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention belong to the scope that the utility model is protected equally.
