Abstract
The utility model relates to a connecting device for high pressure air injecting universal compensated movable pipelines comprising an outer screw thread sealing hoop head with a through hole. The diameter of one end of the through hole is larger than that of the other end. A sealing tightening ring, two cone sealing rings and a compressing ring, a joint of which a sealing head is positioned between the two cone sealing rings and a locknut connected with the outer screw threaded sealing hoop head by a thread are arranged sequentially from inside to outside in the hole with larger diameter. The device has good airproof function and realizes a 100 percent connecting sealing rate for once, which effectively reduces the 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 feeding material needs to be put into a feeding material table, screwing down a slipknot nut with a special wrench, which can be operated by a person so as to effectively reduce labor cost, the utility model also has great range of adjustable connecting angle, can be greatly convenient for the pipeline installation at the special sites and 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 the universal compensation movable pipeline connection set of a kind of high pressure injection vapour
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, the universal compensation movable pipeline of big, the reusable high pressure injection vapour of connection angle adjustable extent is provided.
The universal compensation movable pipeline connection set of high pressure injection vapour described in the utility model, comprise outside thread sealing clip head with through hole, the one end diameter in hole is greater than the other end, in large diameter hole, be provided with sealing and add collar, two conical seal rings, retainer ring, the joint of its sealing head between two conical seal rings and the locking nut that is connected with outside thread sealing clip head thread from interior complying with outward.
One end of described joint has sealing head, and in endoporus, the other end that is positioned at sealing head has screw thread.
The outer surface of described sealing head is smooth arc curved surface or sphere.
Has screw thread in the small diameter bore of described outside thread sealing clip head.
One end of described locking nut has screw thread, and the internal diameter of the other end is less than the external diameter of retainer ring.
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 SEALING FITTING to add excellent matter graphite packing, replaces traditional slips, bolt, once connects sealing effectiveness and has reached 100%, effectively reduces the cost rising that the heat repeatedly blowing out of annotating unit because connecting line leaks vapour causes;
2, the connection angle adjustable extent is big
The movable joint of this device can be done the rotation arbitrarily of 360 degree in inclination maximum is 20 degree scopes, the pipeline that is very easy to special place is installed;
3, simple to operation rapid
This device connect to adopt spherical slip-knot form, has well in the centering performance, only needs during connection filler is put into the filler platform, tightens the slip-knot nut with special spanner, and a people can operate, and effectively reduces human cost;
4, 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 universal compensation movable pipeline connection set of high pressure injection vapour described in the utility model.
Embodiment
Referring to Fig. 1, the universal compensation movable pipeline connection set of high pressure injection vapour described in the utility model, comprise outside thread sealing clip head 1 with through hole, the one end diameter in hole is greater than the other end, in large diameter hole, be provided with sealing and add collar 2, two conical seal rings 3, retainer ring 4, its sealing head joint 6 between two conical seal rings 3 and the locking nut 5 that is threaded with outside thread sealing clip head 1 from interior complying with outward.
One end of described joint 6 has sealing head 7, and in endoporus, the other end that is positioned at sealing head 7 has screw thread, so that connect with the required pipe that is connected.
The outer surface of described sealing head 7 is smooth arc curved surface, is preferably sphere.
Has screw thread in the small diameter bore of described outside thread sealing clip head 1, 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 retainer ring 4.
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.
It is fillers high temperature resistant, high pressure that described sealing adds collar 2.
The sealing head 7 of described joint 6 can adapt to the requirement that is applied to high temperature and high pressure environment through special heat treatment, increases substantially repeated use from number, reaches the purpose that reduces the applying unit cost of raw material.
Put into sealing during installation successively and add collar 2, conical seal ring 3, another conical seal ring 3, retainer ring 4, overlap upper locking nut 5 then and tighten with outside thread sealing clip head 1 and get final product.The termination of locking nut is pressed in and makes two conical seal rings 3 be close to the sealing head 7 of joint 6 on the retainer ring 4, because the surface of sealing head 7 is curved surface or sphere, both diameters are the line contact, even outside thread sealing clip head 1 and joint 6 be not on same shaft axis, also can guarantee fabulous sealing effect, therefore suit especially to install at the pipeline in special place.
