Description
Technical field
The utility model relates to a kind of oil tube pressure test devices, belong to oil pipe processing technique field.
Background technique
In the process of oil pipe, need to detect the air-tightness of oil pipe, and traditional detection air-tightness is usually
When being detected using hydraulic pressure, and carrying out hydraulic pressure detection, since moisture sub-volume is larger, the accuracy of detection is very poor, and hydraulic pressure
It is easy to cause workpiece surface ponding when detection, gets rusty easily, when influencing the service life of workpiece, and being detected using hydraulic pressure, compares
Waste water resource is unfavorable for staff's work, increases labor intensity at winter or lower temperature.
Utility model content
The utility model in view of the above-mentioned deficiencies in the prior art, provides a kind of oil tube pressure test device.
The technical solution that the utility model solves above-mentioned technical problem is as follows:
A kind of oil tube pressure test device, including bottom plate, connecting plate and connecting rod, the connecting rod are fixed on connecting plate and bottom plate
Between, cylinder is equipped on the upside of the connecting plate, the lower end of the cylinder is connected with locating shaft, is equipped with positioning on the upside of the bottom plate
Set is equipped with oil return pipe between the positioning sleeve and locating shaft.
Preferably, the downside of the oil return pipe is uniformly connected with the siphunculus communicated with oil return pipe.
Preferably, the siphunculus is closely located inside positioning sleeve, and the outer rim of the siphunculus is additionally provided with sealing ring.
Preferably, the number of the number at least two of the siphunculus, positioning sleeve and cylinder is identical as siphunculus, and cylinder leads to
Pipe and positioning sleeve are in same vertical line.
Preferably, the number at least two of the connecting rod is uniformly fixed on connecting plate and bottom plate by bolt.
Preferably, the left end of the oil return pipe is cecum, and the right end of oil return pipe is connected with air charging system.
Preferably, the positioning sleeve right side opening is additionally provided with gas leakage gas vent.
Compared with prior art, the utility model has the beneficial effects that air pressure detects, medium molecule is small, accuracy in detection
It is high；Molded part comprehensive detection eliminates composition error caused by assembling after single-piece detects；Finished parts surface non-corrosive.

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
A kind of oil tube pressure test device, including bottom plate 1, connecting plate 2 and connecting rod 3, the connecting rod 3 are fixed on connecting plate 1
Between bottom plate 2, cylinder 4 is equipped on the upside of the connecting plate 2, the lower end of the cylinder 4 is connected with locating shaft 5, on the bottom plate 1
Side is equipped with positioning sleeve 6, and oil return pipe 7 is equipped between the positioning sleeve 6 and locating shaft 5.
The downside of the oil return pipe 7 is uniformly connected with the siphunculus 8 communicated with oil return pipe 7.
The siphunculus 8 is closely located inside positioning sleeve 6, and the outer rim of the siphunculus 8 is additionally provided with sealing ring 9.
The number at least two of the siphunculus 8, positioning sleeve 6 is identical as siphunculus 8 as the number of cylinder 4, cylinder 4, siphunculus 8
With positioning sleeve 6 in same vertical line.
The number at least two of the connecting rod 3 is uniformly fixed on connecting plate 2 and bottom plate 1 by bolt.
The left end of the oil return pipe 7 is cecum, and the right end of oil return pipe 7 is connected with air charging system 10.
6 right side opening of positioning sleeve is additionally provided with gas leakage gas vent 11.
Working principle:
Oil return pipe 7 to be detected is placed on 6 upside of positioning sleeve, siphunculus 8 is inserted into positioning sleeve 6, cylinder 4 passes through positioning
Oil return pipe 7 is fixed axis 5, and air charging system 10 is inflated into oil return pipe 7, and the air pressure of detection oil return pipe 7 can be known whether
Gas leakage, after detection, cylinder 4 drives locating shaft 5 to move up, and oil return pipe 7 is removed.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
