Abstract
An oil well self-pressure relief plug belongs to the technical field of tools. The axis of the end surface is provided with a central hole, and the end surface is welded and connected with the semi-sphere; an oil gas flow inlet channel is arranged on the welding surface of the end surface and the semi-sphere; the oil gas flow inlet channel is connected with the central hole; a straight hole is arranged at the thread and communicated with the central hole; the included angle between the straight hole and the central hole is 90 degrees. The utility model has the advantages that: can dismantle the automatic release of in-process, the staff's that significantly reduces working strength improves work efficiency, has not only avoided the potential safety hazard, and convenient operation has still saved the time moreover. Simple structure, safe and reliable can automatic pressure release under the condition that has the mouth cover not put the excess pressure, has guaranteed the safety of operating personnel's person.
Description
Technical field
The utility model relates to a kind of oil well from the pressure release plug, belongs to technical field of tools.
Background technology
In the manufacturing process of oil well, with plug shutoff well head plug cover, make gas stream safe transport in airtight process pipelines.Also be convenient to check and change plug and dash the pipeline dismounting of sweeping the individual well gathering line.There are the following problems:
1, because common plug commonly used does not possess the releasing pressure automatically function, check oil nozzle or all need remove plug towards sweeping at oil well, the inefficacy of blowdown piping or cock occurs and stop up, directly plug is pulled down, buried potential safety hazard in the real work.
2, thoroughly just do not dismantle plug as not release or release, very easily cause plug to get from the mouthpiece cover, the employee that directly injures causes the accident.
3, Lao Jing is subjected to space constraint that emptying device can't be installed, and plug can only be installed.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of oil well from the pressure release plug.At present, in the oil well production process, because towards sweeping and check that surface choke all will overlap plug with oil nozzle and lay down, but under the situation of or blow-down pipe obstruction malfunctioning at the emptying cock, dismantle the plug operation and have not release or the halfway phenomenon of release, if directly plug is unloaded, very easily cause plug to get from the mouthpiece cover, cause the employee's accident of directly injuring.
A kind of oil well is from the pressure release plug, and there is centre bore in the axle center of end face, and end face and semi-round ball are welded to connect; The solder side of end face and semi-round ball has the gas stream admission passage; The gas stream admission passage connects centre bore;
The screw thread place has straight hole to be connected with centre bore;
The angle of straight hole and centre bore is 90 °.
The diameter of centre bore is φ 6mm, degree of depth 20.5mm; Straight hole is four, and the diameter of straight hole is φ 3mm.
The utility model has the advantages that:
1, in oil field operation district, wind city, to select for use each 1 mouthful of flowing well and pumpingh well that the utility model is installed and use, effect is fine.Owing to the utlity model has good pressure release effect, can be in unloading process automatically unloading, significantly reduce employee's working strength, increase work efficiency, not only avoided potential safety hazard, and easy to operate, also saved the time.
2, simple in structure, safe and reliable, can avoid when operation the plug band press situation such as get, reduce labour intensity, increase work efficiency.Have muzzle not put under the situation of overbottom pressure can releasing pressure automatically, guaranteed the safety of operative employee's person.
Description of drawings
When considered in conjunction with the accompanying drawings, by the reference following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide further understanding of the present utility model, constitute a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model, as figure wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is further specified.
The specific embodiment
Obviously, the many modifications and variations done based on aim of the present utility model of those skilled in the art belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of oil well is from pressure release plug 1, and there is the centre bore 4 of diameter phi 6mm, degree of depth 20.5mm in the axle center of end face 6, and end face 6 is welded to connect with semi-round ball 7; End face 6 has gas stream admission passage 3 with the solder side of semi-round ball 7;
Screw thread 2 places have four straight holes 5 of diameter phi 3mm to be connected with centre bore 4, form four pressure release paths, and gas stream admission passage 3 connects centre bore 4;
When plug was dismantled the pressure release section, the gas stream behind the plug was discharged from relief hole by entering behind the linked hole of center, hole, and pressure leaks automatically, and the pressure release path is that the center communication passage has been cut down the impact force that 1 times oil gas leaks, and can not cause the person and hurt sb.'s feelings.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from inventive point of the present utility model and effect in fact can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the present utility model.
Claims (2)
