Embodiment
Preferred embodiment
As shown in Figure 1, a kind of pick-up unit detecting freezing pipe 4 sealing, comprises and suppresses pipeline 1, described in suppress pipeline 1 one end with suppress equipment connection, described in suppress pipeline 1 the other end be connected with the first connector 2;
Described suppressing on pipeline 1 is provided with the pressure-detecting device 3 that the pressure medium in pipeline 1 is suppressed in detection;
Freezing pipe 4 has a medium container cavity 41, described medium container cavity 41 is in communication with the outside by the opening be located on described freezing pipe 4, described first connector 2 is connected with described opening air-tight movable, air-tight movable connects and thread seal can be adopted to connect this connected mode or Flange joint or other to be tightly connected mode, as long as the first connector 2 can be tightly connected with opening, described first connector 2 is hollow structure, described in suppress pipeline 1, described first connector 2 is communicated with described medium container cavity 41.
In order to improve the life-span of the present invention further, the outer wall of freezing pipe 4 is fixed with cover plate 5, described cover plate 5 is provided with cover board hole 51, and the position of described cover board hole 51 is corresponding with the position of described opening; Described cover plate 5 top is fixed with the second connector 6 coordinated with described first connector 2, and described second connector 6 is provided with the second connector through hole 61, and described second connector through hole 61 is corresponding with the position of described cover board hole 51.Cover plate 5 and the second connector 6 are set between freezing pipe 4 and the first connector 2, the first connector 2 is prevented to be connected directly between on freezing pipe 4, freezing pipe 4 is impacted, affect the serviceable life of freezing pipe 4, and freezing pipe 4 is generally weldless steel tube, its cost is higher, and the power that the first connector 2 coordinates with the second connector 6 is evenly delivered on cover plate 5 through the second connector 6 and cover plate 5, thus the surperficial uniform force of freezing pipe 4 that guarantee is connected with cover plate 5, extend the life-span of the present invention.
First connector 2 selects hollow screw rod, and the second connector 6 selects nut, and described screw rod matches with described nut.
Described pressure-detecting device 3 is tensimeter.This tensimeter can be the tensimeter of tracer liquid pressure or the tensimeter of detection gaseous tension, in like manner of the present invention suppress equipment can select to suppress pipeline 1 squeeze into liquid equipment of suppressing or squeeze into gas suppress equipment, suppress equipment when squeezing into gas and can select air compressor machine, when squeezing into liquid, can pump be selected.
The first connector 2 is unloaded after detection, when again detecting, the mud be positioned near opening can flow into medium container cavity 41 from opening, after detection terminates, mud easily enters freezing pipe 4 by the hole be opened on cover plate 5 and freezing pipe 4, impact is suppressed the work of equipment, is shortened the life-span of equipment of suppressing, mud enters freezing pipe 4 simultaneously, can solidify when freezing operation and be frozen in freezing pipe 4, cause the feed pipe of transporting low temperature refrigerant be frozen in the mud freezed and cannot remove, cause construction inconvenience.So in order to stop mud to flow into medium container cavity 41, the present invention also comprises block head, and described block head coordinates with described opening, after removing the first connector 2 after detection, use block head to be sealed by opening, thus prevent mud to flow in medium container cavity 41.
Blowdown valve 7 is installed suppressing on pipeline 1.After detection, suppress pressure in pipeline 1 comparatively large, when the first connector 2 being pulled down, for security consideration, need the pressure suppressed in pipeline 1 to discharge, blowdown valve 7 is set, be convenient to by the earth pressure release suppressed in pipeline 1 out, handling safety.
Described suppress pipeline 1 comprise vertically arrange first suppress pipeline 11, freezing pipe 4, described cover plate 5, described nut, described screw rod, described first suppress pipeline 11 and described pressure-detecting device 3 is arranged from bottom to top.By freezing pipe 4, cover plate 5, nut, screw rod, first suppresses pipeline 11 and pressure-detecting device 3 is arranged from bottom to top, constructability operation, improves construction operation efficiency.
Described pipeline 1 of suppressing also comprises horizontally disposed second and suppresses pipeline 12, described blowdown valve 7 is arranged on described second and suppresses on pipeline 12, described second suppresses pipeline 12 and described first suppresses pipeline 11 and is communicated with, described second suppresses pipeline 12 in the vertical direction between described screw rod and described pressure-detecting device 3, and the length of the pick-up unit vertical direction of described detection freezing pipe 4 sealing is greater than five times of the length of the pick-up unit horizontal direction of described detection freezing pipe 4 sealing.Constructability operation, improves construction operation efficiency.
Principle of work of the present invention is as follows: be tightened on by screw rod on nut, thus the present invention is fixed, install at the second free end suppressing pipeline 12 and suppress equipment, start and suppress equipment, flow media is squeezed in pipeline, along with the medium suppressed in pipeline 1 increases manometric vertical rising, observe manometric force value, close when reaching certain value and suppress equipment, whether the force value prolongation in time observing tensimeter instruction can decline, then illustrate that freezing pipe 4 sealing is enough when not prolongation in time declines, then illustrate that freezing pipe 4 sealing is inadequate when prolongation in time declines.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
