Abstract
The utility model relates to a cup type riser pressure sensor's glass protection architecture that glues, including cylinder body liner, fastening screw and plug, its characterized in that: the cylinder body liner is fixed in the cylinder body bottom by fastening screw, and the cylinder body bottom outlet is plugged up to the plug. The utility model discloses an essential element is exactly the cylinder body liner, and the effect is the gluey cup of protection, and its characteristics firstly external diameter of cylinder body liner are less than cylinder body internal diameter 0.5 -1mm, and the space is pressed with the clearance constitution annular biography of cylinder body inner wall to the cylinder body liner, avoids opening the biography and press the hole on the cylinder body liner, can not contact the crude sharp edge's of having metal when letting gluey cup atress inflation, and rip gluey cup, its characteristics secondly one end are bowl form concave curved surface down, and bottom of cup portion shape is the same with gluing, can hold during gluey cup inflation and glue the cup, and it is even that the messenger glues the cup atress, is difficult for breaking, its characteristics thirdly other end are the plane, open threaded hole, make its can by the fastening on cylinder body inside terminal plane, can not become flexible in the cylinder body.
Description
Technical field
This utility model relates to a kind of plastic cup-type standpipe pressure sensor, is specifically related to the glue cup protection structure of a kind of plastic cup-type standpipe pressure sensor.
Background technology
Standpipe pressure is during oil drilling or workover treatment, needs the drilling parameter measured.Mud pressure in standpipe acts on transmission medium by the glue cup in sensor, and transmission medium handle riser pressure is delivered to display table again.At present, being widely used in the plastic cup-type standpipe pressure sensor of oil drilling industry due to operating pressure transient change relatively greatly, the glue cup for pressure transmission is susceptible to spalling, mud is caused to enter pressure transmission pipeline, damage display table, change glue cup frequently, make troubles to drillng operation.Therefore, necessary design is a kind of can effectively protect glue cup to reduce the standpipe pressure sensor that glue cup ruptures.
Fig. 4 is the plastic cup-type standpipe pressure sensor construction figure before improving, Fig. 5 is the plastic cup-type standpipe pressure working sensor schematic diagram before improving, its shortcoming is, when in glue cup, mud pressure is excessive, transmission medium lacks, glue cup drawn expanded easily enters in the oil-through hole of cylinder bottom, blocks pressure transmission hole, causes glue cup to tear, mud pours into pressure transmission pipeline, damages Pressure gauge.
Summary of the invention
This utility model technical issues that need to address are, overcome the deficiency of background technology, propose the plastic cup-type standpipe pressure sensor glue cup protection structure of a kind of advantages of simple, and the situation ruptured to reduce glue cup occurs.
This utility model solves its technical problem and be the technical scheme is that
The glue cup protection structure of a kind of plastic cup-type standpipe pressure sensor, including cylinder body liner, trip bolt and plug, it is characterised in that: cylinder body liner is fixed on cylinder base by trip bolt, and plug blocks cylinder body bottom outlet.
Described cylinder body liner one end is bowl-shape lower concave curved surface, identical with glue cup bottom shape, can hold glue cup, uniform force when glue cup expands, is not easily broken, and the cylinder body liner other end is plane, it is provided with screwed hole, is fastened by bolts in cylinder bottom plate, will not loosen in cylinder body.
The external diameter of described cylinder body liner is less than cylinder diameter 0.5mm～1mm, cylinder body liner constitutes annular pressure transmission space with the gap of inboard wall of cylinder block, pressure transmission hole do not opened by cylinder body liner, ensure that glue cup does not has sharp and crude metal covering with the contact surface of cylinder bottom, glue cup is avoided to be scratched, slow down hydraulic oil flow velocity in cylinder body simultaneously, reduce the impact to executive component.
This utility model is simple and reliable for structure, easy for installation.Extending the glue cup life-span, decrease glue cup replacement frequency, this structure has throttling action simultaneously so that the temporary impact that inner member is subject to reduces, and gauge hand quickly stabilizes.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail:
As it is shown in figure 1, this utility model includes cylinder body liner 4, trip bolt 3 and plug 2, it is characterised in that: cylinder body liner 4 is fixed on bottom cylinder body 1 by trip bolt 3, plug 2 tightly wraps raw material band and blocks cylinder body 1 bottom outlet.As shown in Figure 3 a, 3 b, described cylinder body liner 4 one end is bowl-shape lower concave curved surface, identical with glue cup 6 bottom shape, glue cup 6, uniform force when glue cup 6 expands can be held, be not easily broken, cylinder body liner 4 other end is plane, it is provided with screwed hole, is fastened by bolts on cylinder body 1 base plate, will not loosen in cylinder body 1.
The external diameter of described cylinder body liner 4 is less than cylinder diameter 0.5-1mm, cylinder body liner 4 constitutes annular pressure transmission space with the gap of cylinder body 1 inwall, pressure transmission hole do not opened by cylinder body liner 4, ensure that glue cup 6 does not has sharp and crude metal covering with the contact surface of cylinder bottom, glue cup 6 is avoided to be scratched, slow down hydraulic oil flow velocity in cylinder body 1 simultaneously, reduce the impact to executive component.
As in figure 2 it is shown, during working sensor, when in glue cup 6, mud pressure is relatively big, glue cup 6 stretches, cylinder body liner 4 sphere can hold glue cup 6 cup so that it is uniform force will not rupture, and ensure that glue cup will not block pressure transmission hole after swelling simultaneously.
Fig. 4 is the plastic cup-type standpipe pressure sensor construction figure before improving, Fig. 5 is the plastic cup-type standpipe pressure working sensor schematic diagram before improving, its shortcoming is, when in glue cup, mud pressure is excessive, transmission medium lacks, glue cup drawn expanded easily enters in the oil-through hole of cylinder bottom, blocks pressure transmission hole, causes glue cup to tear, mud pours into pressure transmission pipeline, damages Pressure gauge.
