Abstract
The utility model discloses a hydraulic non-return pressure gage joint which is used for connecting pressure equipment and pressure gages and overcoming the using defect of the pressure gage joint. The hydraulic non-return pressure gage joint comprises a lower joint, wherein a hydraulic non-return mechanism is arranged in the lower joint; the lower joint is connected with an upper joint through a locking nut; an upper sealing gasket is arranged in the upper joint; and a lower sealing gasket is arranged between the upper joint and the lower joint. The using defect of the conventional pressure gage joint is overcome, and by adopting a gasket sealing method, the operation regulation is met. The required orientation of the pressure gage can be obtained by directly rotating the pressure gage, the pressure gage is conveniently managed, and convenience is provided for observing and recording the pressure gage. By adopting the hydraulic non-return mechanism, the problem of liquid or gas leakage in the process of replacing the pressure gage is solved, so that the safety in the process of replacing the pressure gage is improved, the replacement process is simplified, the working efficiency is improved, and the joint has a good using effect.
Description
Technical field
The utility model relates to manometric coupling arrangement, and particularly hydraulic pressure non-return pressure tapping is used for press device and is connected with manometric, solves the use defective that pressure tapping exists.
Background technology
Pressure is the whether important indicator of operate as normal of reflection pressure system work.Manometric installation whether standard has directly reflected the field management level of pressure system.Pressure tapping commonly used at present is a dead joint that has interior screw thread and male thread; This joint exists following problem: 1, during execute-in-place; Sealing between tensimeter and the pressure tapping generally adopts the winding method of twining polytetrafluoroethylraw raw material band to solve; Poorly sealed, do not meet working specification yet.2, use at the scene in if guarantee non-leakagely, then be difficult to guarantee manometric towards the direction that is job requirement, influence the field management level.3, the tensimeter valve receives the erosion of oil gas water, often fits badly, and tensimeter can't be changed qualified tensimeter after damaging quickly and easily.Total valve that must the closing presure system could be changed tensimeter after putting net pressure, and operation is loaded down with trivial details.
Summary of the invention
The purpose of the utility model provides the pressure tapping of hydraulic pressure non-return, adopts the sealing of cushioning method, need not valve-off and also can normally change tensimeter, conveniently manages, satisfies simultaneously tensimeter and adjust the requirement of direction, improve management quality.
Following technical proposals can reach above-mentioned purpose: the pressure tapping of hydraulic pressure non-return comprises lower sub; The hydraulic pressure non-return mechanism is housed in lower sub; Lower sub is connected with top connection through set nut, and sealing gasket is housed in top connection, and the lower seal pad is housed between top connection and lower sub.
The utlity model has following useful effect: the utility model has solved the above-mentioned use defective that present pressure tapping exists, and adopts the sealing of cushioning method, the match operation rules.Directly the rotation pressure table needing can obtain tensimeter towards, made things convenient for management, for manometric observation and record provide convenience.The liquid in the employing hydraulic pressure non-return mechanism solution tensimeter replacing process or the leakage problem of gas have not only increased the security when changing tensimeter, have also simplified the replacing flow process, have improved work efficiency, have result of use preferably.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
Do further detailed description below in conjunction with 1 pair of the utility model of accompanying drawing: referring to accompanying drawing 1; The pressure tapping of hydraulic pressure non-return comprises lower sub 7, and the hydraulic pressure non-return mechanism is housed in lower sub 7, and lower sub 7 is connected with top connection 1 through set nut 2; Sealing gasket 9 is housed in top connection 1; Between top connection 1 and lower sub 7, lower seal pad 3 is housed, adopts the sealing of cushioning method, solve manometric leakage problems and towards problem.The hydraulic pressure non-return mechanism comprises spool 4, spring 5 and adjusting bolt 6, and spool 4, spring 5 and adjusting bolt 6 are installed in the inner chamber of lower sub 7, and the upper body of spool 4 is inserted in the upper end center pit of lower sub 7, mounting spring 5 between spool 4 and adjusting bolt 6; The external diameter of spool 4 upper body gets into the admission passage of top connection 1 less than the internal diameter of lower sub 7 upper end center pits as liquid or gas.Regulate bolt 6 and be provided with side in center pit and the adjusting, center pit connects with the interior side of adjusting, as the admission passage 8 of the utility model liquid or gas.Top connection 1 one end inner chambers connect the pressure gauge outfit, and the other end is provided with end cap, and central enclosure and end cap are provided with center pit, and the cylindrical screw thread of central enclosure is connected with set nut 2.Top connection 1, the center pit perforation of going up sealing gasket 9, lower seal pad 3 become manometric admission passage.Liquid or gaseous tension are got in the lower sub 7 by the admission passage of regulating on the bolt 68, get in the top connection 1 through spool 4 pressure is reflected on the tensimeter again.Unload when uncaging jack panel 2, spool 4 is closed admission passage automatically under the effect of spring 5, has guaranteed operating personnel's safety.Lower sub 7 is installed on the tensimeter valve by standard operation, choose manometric towards, utilize set nut 2 that top connection 1 closely is connected with lower sub 7.This moment, lower seal pad 3 was realized sealing under the extruding of top connection 1 and lower sub 7, solved manometric seepage simultaneously and reached towards problem.
