Abstract
The pressure gauge joint is applied to connecting and fixing the pressure gauge. And an external thread is arranged at one end of the fixed joint, and a regular hexagon body is arranged on the outer wall at the other end of the fixed joint. A T-shaped connector is welded in a central hole at one end of the regular hexagon of the fixed joint. The T-shaped connector is cylindrical and is provided with a central hole, and the outer wall of the upper end of the cylinder is provided with a convex annular body; the other end of the T-shaped connecting body is provided with a movable connecting cap; the annular body of the T-shaped connector is arranged in the movable connecting cap; one end in the movable connecting cap is provided with an internal thread connected with the pressure gauge, and the other end in the movable connecting cap is provided with an annular body protruding inwards. The effect is as follows: the pressure gauge can be connected, the operation is convenient when the pressure gauge is replaced or installed, and the working efficiency is improved.
Description
Technical field
The utility model relates to manometric erection joint.What be particularly related to a kind of activity is convenient to install, change manometric joint.
Background technology
At present, replacing or setting pressure table are a kind of comparatively frequent maintenance operation work on the oil gas field device.During installation, the external thread body of tensimeter lower end is fixed on the internal thread of pressure tapping.Be that pressure tapping one end has external thread, the other end has the manometric internal thread of connection, and positive hexahedron is arranged on the outer wall of female end, and positive hexahedron is that back-up wrench is used.When changing the setting pressure table in the past,, therefore when replacing, setting pressure table, all tighten the positive tetragonal body or the positive hexahedron of tensimeter bottom with spanner because pressure tapping is fixed on the operation valve.Because the pressure watchcase is too near with the distance of positive hexahedron, skids easily with spanner the time, there is potential safety hazard in fragile pressure tapping.Sometimes the employee removes the pressure dial plate with hand and tightens, and easily the build-up of pressure table damages, and does not meet normalizing operation, influences employee's operating speed.
The utility model content
The purpose of this utility model is: a kind of pressure tapping is provided, can connects tensimeter, and easy to operate when replacing or setting pressure table, increase work efficiency.
The technical solution adopted in the utility model is: pressure tapping, mainly by fixture splice, T shape connector with flexibly connect cap and form, fixture splice has center pit, at an end of fixture splice external thread is arranged, and positive hexahedron is arranged on the outer wall of the fixture splice other end.It is characterized in that: in the center pit of positive hexahedron one end of fixture splice, be welded with a T shape connector.T shape connector has center pit for the cylinder bodily form, and the annular solid of protrusion is arranged at cylindrical upper end outer wall; The other end at T shape connector has one to flexibly connect cap; The annular solid of T shape connector is in flexibly connecting cap; Described flexible connection cap is positive hexahedron shape, and an end has the manometric internal thread of connection in flexibly connecting cap, flexibly connects the oriented projecting inward annular solid of the other end in the cap.
In order to increase T shape connector and to flexibly connect sealing between the cap, the annular solid lower plane that protrudes at T shape connector and flexible connection cap are between the plane O-ring seal being arranged on the projecting inward annular solid.
Rotation when replacing, setting pressure table, makes things convenient for the staff to operate flexibly between T shape connector and the flexible connection cap.
The beneficial effects of the utility model: the utility model pressure tapping, can connect tensimeter, easy to operate when replacing or setting pressure table, improved work efficiency.Rig-site utilization proves that this pressure tapping making is simple, convenient to operation, practical, and tensimeter numerical value transmits the accuracy height, has thoroughly eliminated the security risk that exists when changing the setting pressure table in the past.
Description of drawings
Fig. 1 is the utility model pressure tapping structural profile synoptic diagram.
Among the figure, the 1-fixture splice, 2-T shape connector, 3-flexibly connects cap.
Embodiment
Embodiment 1: with a pressure tapping is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model pressure tapping mainly is made up of fixture splice 1, T shape connector 2 and flexible connection cap 3.It is the center pit of 12.5mm that fixture splice 1 has internal diameter, at an end of fixture splice 1 external thread of M20 is arranged, and on the outer wall of fixture splice 1 other end positive hexahedron is arranged.In the center pit of fixture splice 1 positive hexahedron one end, be welded with a T shape connector 2.The necessary secure seal of pad can be born high pressure.T shape connector 2 is the cylinder bodily form of diameter 12mm, and it is the center pit of 6mm that T shape connector 2 has diameter, at cylindrical upper end outer wall the annular solid of protrusion, the external diameter 17.5mm of annular solid, thickness 5mm is arranged; The other end at T shape connector 2 has one to flexibly connect cap 3.The annular solid of T shape connector 2 is in flexibly connecting cap 3.Described flexible connection cap 3 profiles are positive hexahedron shape, and an end has the manometric internal thread (M20) of connection in flexibly connecting cap 3, flexibly connect the oriented projecting inward annular solid of the other end in the cap 3, to projecting inward annular solid internal diameter 12.5mm, thickness 5mm.
The annular solid lower plane that protrudes at T shape connector 2 with flexible connection cap 3 between the plane rubber seal being arranged on the projecting inward annular solid.
