Abstract
The utility model provides a pressure testing device for an oil well packing box, which comprises a flanged joint and threaded connectors, wherein the flanged joint and the threaded connectors are connected with a booster pump pipeline for providing air pressure respectively via valves. The pressure testing device provided with two kinds of interfaces carries out predelivery test or pre-mounting test on a new packing box so as to test the sealing effects; through adjusting pressure of the booster pump, sealing of the packing box under different pressures can be tested, so as to improve the adaptability; and the pressure testing device for the oil well packing box has the advantages that the structure is simple, the connection is convenient, the test is accurate, oil leak and oil injection phenomena at the wellhead can be avoided and reduced, and loss is reduced.
Description
Technical field
The utility model relates to a kind of oil production equipment, is specifically related to the device that a kind of tight head that is used for the sealing oil pumping polish rod to being arranged on production wellhead carries out pressure testing.
Background technology
Tight head is a kind of and the matching used packoff of oil recovery machiner; be arranged on the production wellhead place; utilize inner packing to contact with sucker rod polished rod; thereby form sealing between oil pumping polish rod and production wellhead inside; tight head is divided into flange form tight head and screw thread type tight head according to the difference of connected mode; and be the intensity of protection tight head; the main body of tight head is to form one by welding; therefore just need to carry out the inner sealing property testing before installation, to determine the sealing of packing and tight head.
The utility model content
For the good tight head of sealing being provided and reducing accident rate, the utility model provides a kind of pressure testing device that new tight head is carried out performing leak test.Concrete scheme is as follows: a kind of pressure testing device of oil-well packing box, it is characterized in that, and comprise bump joint and screwed connection body, described bump joint is connected with the screwed connection body by valve and is connected with the supercharge pump pipeline that gaseous tension is provided.
For convenience of testing and carrying: also comprise the support frame of a rectangle, be provided with installation panel at the top of support frame, described bump joint and screwed connection body are fixed on installation panel, and described valve and supercharge pump install pipeline are in support frame.
Measure efficient for improving: described bump joint and screwed connection body are connected on same supercharge pump pipeline by valve respectively.
Preferred mounting means is: be respectively arranged with the through hole corresponding with bump joint and screwed connection shape on described installation panel, bump joint and screwed connection body are bolted on installation panel after inserting through hole.
The utility model is tested before dispatching from the factory or installing new tight head by the pressure testing device with two kinds of interfaces, to detect sealing effectiveness, by adjusting the pressure size of supercharge pump, can detect tight head in the sealing of different pressures, to improve adaptive faculty.The utility model is simple in structure, easy to connect, and measurement effect is accurate, can avoid and reduce production wellhead generation leakage of oil, fuel injection event, reduces the loss.
Description of drawings
Fig. 1 structural representation of the present utility model;
Fig. 2 vertical view of the present utility model.
Label declaration in accompanying drawing: 1-bump joint, 2-screwed connection head, 3-valve, 4-supercharge pump pipeline, 5-support frame, 501-installation panel.
Embodiment
As shown in Figure 1, the pressure testing device of oil-well packing box of the present utility model comprises bump joint 1 and screwed connection body 2, and bump joint 1 is connected with the screwed connection body and is connected with the supercharge pump pipeline 4 that gaseous tension is provided by valve 3 respectively.
When work, difference according to the tight head joint, it is arranged on corresponding bump joint 1 or screwed connection body 2, close simultaneously the valve 3 of another bump joint 1 or screwed connection body 2, whether start supercharge pump and inject air pressure by supercharge pump pipeline 4 in the pipeline that has connected tight head, detecting current tight head according to the variation of air pressure has leakage.Can adopt corresponding parts to replace oil pumping polish rod to come the other end of sealed packing box when measuring.
For convenient test, the utility model is arranged on pressure testing device on the support frame 5 of a rectangle, be provided with installation panel 501 at the top of support frame 5, bump joint 1 and screwed connection body 2 are fixed on installation panel 501, and valve 3 and supercharge pump pipeline 4 are arranged in support frame 5.The carrying that provides such structure can facilitate pressure testing device simultaneously also for surveying work provides an operating platform, makes the easier for installation of tight head.Be the annexation between minimizing equipment, simplified structure, in the utility model, bump joint 1 and screwed connection body 2 are connected on same supercharge pump pipeline 4 by valve 3 respectively.When test, can measure simultaneously as required the tight head of one or two distinct interface like this, greatly improve and measure efficient.
In order to be easy for installation and removal, the utility model is respectively arranged with the through hole corresponding with bump joint 1 and screwed connection body 2 shapes on installation panel 501, is bolted on installation panel 501 after bump joint 1 and screwed connection body 2 insert through hole.
the above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, anyly be familiar with the technician of this patent within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned prompting is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of the utility model scheme.
