Description
Technical field
the utility model relates to and is used for tube element axial restraint self-locking device technical field, is a kind of tubulose steel loop self-locking device.
Background technology
all are to be contained in the holder tube at the tester of type well, oil well, salt well, geothermal well usually; The complex structure of holder tube will take bigger annular space, reduces the area of passage of fluid passage, when test manufacture meter fluid output; Because of the area of passage of fluid passage reduces; Traffic requirement when not reaching test manufacture, the pressure of measuring fluid does not just reflect the borehole fluid actual pressure, thereby can not satisfy the data demand when test-manufacturing.
Summary of the invention
the utility model provides a kind of tubulose steel loop self-locking device; Overcome the deficiency of above-mentioned prior art, it can effectively solve because the fluid pressure that the area of passage of fluid passage causes measuring for a short time can not reflect the problem of borehole fluid actual pressure.
The technical scheme of
the utility model realizes through following measure: a kind of tubulose steel loop self-locking device comprises joint, ring body and locking device; The narrow cone boss in the left wide right side is arranged at the middle part of joint; Ring body is sleeved in the left part of joint, and the right part of ring body is taper left large and right small and is sleeved in the cone boss, and the right-hand member outside of the ring body corresponding with cone boss is equipped with locking device, and locking device contacts with cone boss.
Be to the further optimization of above-mentioned utility model technical scheme below or/and improve:
above-mentioned locking device can comprise that two support choma and opening pressure ring; The mounting groove that the ring-type U-shaped is arranged in the right-hand member outside of ring body; Inner and inside, right side is separately installed with and supports choma in the centrosymmetric left side of mounting groove; In two outsides that support choma the opening pressure ring is installed, the outer end of opening pressure ring is positioned at the mounting groove outside and contacts with cone boss.
Can there be conical internal thread the left part inboard of
above-mentioned joint, and the joint right part outside has conical external screw thread respectively.
the utility model reasonable and compact in structure, easy to use; It can effectively improve the area of passage of fluid passage, has therefore greatly improved the accuracy of measuring.

The specific embodiment
the utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
are in the utility model; For the ease of describing; The description of the relative position relation of each parts all is to describe according to the Butut mode of Figure of description 1, as: the position relation of upper and lower, left and right etc. is what to confirm according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
shown in accompanying drawing 1, this tubulose steel loop self-locking device comprises joint 1, ring body 2 and locking device; The narrow cone boss 3 in the left wide right side is arranged at the middle part of joint 1; Ring body 2 is sleeved in the left part of joint 1, and the right part of ring body 2 is taper left large and right small and is sleeved in the cone boss 3, and the right-hand member outside of the ring body 2 corresponding with cone boss 3 is equipped with locking device, and locking device contacts with cone boss 3.
Can according to actual needs above-mentioned tubulose steel loop self-locking device be done further to optimize or/and improve:
like accompanying drawing 1,3,4,6, shown in 7, locking device comprises that two support choma 4 and opening pressure ring 5; The mounting groove 6 that the ring-type U-shaped is arranged in the right-hand member outside of ring body 2; Inner and inside, right side is separately installed with and supports choma 4 in the centrosymmetric left side of mounting groove 6; In two outsides that support choma 4 opening pressure ring 5 is installed, the outer end of opening pressure ring 5 is positioned at mounting groove 6 outsides and contacts with cone boss 3.Like this, be convenient to the installation and removal of ring body 2 and joint 1.
have conical internal thread in the left part inboard of joint 1 shown in accompanying drawing 1, there is conical external screw thread in the joint 1 right part outside; Being convenient to the utility model is connected with other devices.
above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The installation and removal process of
the utility model most preferred embodiment: at first the left end with this utility model is installed in the trustship through screw thread, and the pipe fitting corresponding with ring body 2 arranged in trustship; In the process that trustship and joint 1 are screwed; Pipe fitting and ring body 2 in trustship and the joint 1 axially hold out against; Make body individual end thrust to the right arranged with respect to ring body 2; The right-hand member that thrust promotes ring body 2 holds out against on cone boss 3, and at this moment the opening pressure ring 5 in the mounting groove 6 receives the pressure of cone boss 3, makes opening pressure ring 5 and support choma 4 to be pressed in the mounting groove 6; Because opening pressure ring 5 and self yield force that supports choma 4 are radially fixing when making joint 1 with opening pressure ring 5 axial restraints; When dismounting, trustship and the utility model are outwarded winding, make pipe fitting break away from ring body 2; Since opening pressure ring 5 with support choma 4 and receive the yield force effect always; After losing end thrust, opening pressure ring 5 is moved to the left along cone boss 3, thereby ring body 2 and joint 1 are broken away from.
