Abstract
The utility model relates to a connecting device for high pressure air injecting movable pipelines comprising an outer screw thread sealing hoop head 1 and 4 which are connected by a locknut 2 and a sealing steel ring 3 arranged between the sealing hoop head 1 and the sealing hoop head 4. The device has good airproof function and realizes a 100 percent connecting sealing rate for once, which effectively reduces the rising cost of a burning unit caused by a plurality of shutdowns for air leakage of the connecting pipelines. The utility model has good self-aligning function by adopting a screw thread slipknot form and when in connection, only the steel ring needs to be put into the hoop head, screwing down a slipknot nut by a special wrench, which can be operated by a person so as to effectively reduce the labor cost, the utility model also can be used repeatedly based on safety and high efficiency, thus avoiding dangers caused by over or less pre-tightening torque.
Description
Technical field
The utility model relates to the connection set of petroleum production with the high temperature and high pressure steam delivery pipe., specifically, relate to a kind of connection set of high pressure injection vapour movable pipeline
Background technique
Oil field tradition thickened oil recovery is adopted slips, bolt form with the connection of high temperature and high pressure steam delivery pipe, has following defective:
1, complicated operation, the pipeline joint efficiency is lower, the human cost height, and link is designed to disposable use, the cost of material height;
Need step up with sledgehammer hammering centering when 2, operating, because bolt pretightening is not easy to determine, cause the localized stress of connecting bolt excessive or too small, stress is excessive, and then bolt easily fractures, and produces dangerous, and understressing, then poorly sealed, need the blowing out mending-leakage behind the notes vapour, cause notes vapour expense degree significantly to rise;
3, the angle adjustable of pipeline attachment portion is little, and the construction physical features needs smooth, the needs of incompatibility oil field field work;
The operator beat slips, bolt for Jin Indium steel ring with sledgehammer when 4, pipeline connected, and often ruptured, and caused slips, bolt to cause potential dangerous and raw-material waste.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and the connection set of a kind of good seal performance, high pressure injection vapour movable pipeline easy and simple to handle, reusable is provided.
The connection set of high pressure injection vapour movable pipeline described in the utility model comprises the outside thread sealing clip head, sealing clip head and the sealing steel rings between above-mentioned two clip heads that are connected by locking nut.
The outer surface of described steel ring is smooth arc curved surface or sphere, and described outside thread sealing clip head has the plane of inclination with the endoporus that sealing clip head contacts with steel ring, and its other end has internal thread.
Described plane of inclination is the plane, or with the radius of curvature curved surface inequality of the outer surface of steel ring.
One end of described locking nut has screw thread, and the internal diameter of the other end is less than the external diameter of sealing clip, and its end face has screw, and screw is housed in the hole, and the outer surface of the end that sealing clip head contacts with steel ring has the plane of inclination.
Connecting thread between described locking nut and the outside thread sealing clip head is common V thread screw or trapezoidal thread.
The connection set of high pressure injection vapour movable pipeline described in the utility model has the following advantages and technique effect:
1, good seal performance
This device adopts spherical steel ring, once connects sealing effectiveness and has reached 100%, effectively reduces the cost that the heat repeatedly blowing out of annotating unit because connecting line leaks vapour causes and rises.
2, simple to operation rapid
This device connect to adopt screw thread slip-knot form, has well in the centering performance, only needs during connection steel ring is put into the clip head, tightens the slip-knot nut with special spanner, and a people can operate, and effectively reduces human cost;
3, can reuse safely and efficiently
The pre-fastening moment of this device through calculating, is controlled by reach, as long as with the slip-knot nut screwing clamping, can reach desirable pre-fastening moment, has avoided the danger that may bring because pre-fastening moment is excessive or too small.The material of this device can adapt to the requirement of applied environment High Temperature High Pressure through special heat treatment, increases substantially the repeated use number of times, reaches the purpose that the user reduces the cost of raw material.
Description of drawings
Fig. 1 is the main pseudosection of the connection set of high pressure injection vapour movable pipeline described in the utility model;
Embodiment
Referring to Fig. 1, the connection set of high pressure injection vapour movable pipeline described in the utility model comprises outside thread sealing clip head 1, sealing clip head 4 and the sealing steel rings 3 between above-mentioned two clip heads that is connected by locking nut 2.
The outer surface of described steel ring 3 is smooth arc curved surface, is preferably sphere.
Described outside thread sealing clip head 1 has the plane of inclination with sealing clip head 4 with the endoporus that contacts of steel ring 3, this face can be the plane, it also can be radius of curvature curved surface inequality with steel ring 3 outer surfaces, so that both contacts are the line contact, guarantee splendid sealing effect, its the other end has internal thread, so that connect with the required pipe that is connected.
One end of described locking nut 2 has screw thread, and the internal diameter of the other end is less than the external diameter of sealing clip 4, and its end face has screw, and screw 5 is housed in the hole, and the outer surface of the end that sealing clip head 4 contacts with steel ring has the plane of inclination.
Connecting thread between described locking nut 2 and the outside thread sealing clip head 1 can be common V thread screw, also can be trapezoidal thread.The trapezoidal thread join strength is big, and it is also big to bear moment.
The material of described outside thread sealing clip head 1, steel ring 3 and sealing clip head 4 can adapt to the requirement of applied environment High Temperature High Pressure through special heat treatment, increases substantially the repeated use number of times, can reduce user's user cost effectively.
During installation locking nut 2 is sleeved on the sealing clip head 4, when locking nut 2 outside thread is sealed clip head 1 and sealing clip head 4 is connected fastening after, fix with screw 5, prevent that link from becoming flexible.
