Abstract
The utility model relates to a side seal hammering union. The problem of the damaged, the thorn phenomenon of sealing washer easily appears in current hammering oil nonyl is mainly solved. The method is characterized in that: public first (4) outside is arranged in female head (1), and is equipped with O type sealing washer (2) on the two contact surface, female head (1) outside threaded connection has lock nut (3), public first (4) surface is equipped with the step, the step card is on the ladder face of lock nut (3) inside, and closely cooperates between lock nut (3) and public head (4). The side seal hammer union can avoid the phenomena of damage of a seal ring and leakage of the union caused by hammer union in the process of circular operation, thereby avoiding environmental pollution and improving construction quality.
Description
Technical field
The utility model is related to a kind of field of oil field oil extraction, specifically a kind of for connecting various following in underground work
The oily nonyl of side seal hammering of endless tube line.
Background technology
At present, need for ground workover fluid pump truck to pump into well by surface line in underground work, during cycle operation
It is interior, in the process in order that by gas cut and not ensureing downhole tool work well, it is necessary to uninterrupted into the workover fluid in well
Circulation and enough pressure as guarantee.Surface line length is general all in more than 20m in site operation, is led to by several pipelines
The oily nonyl of hammering is crossed to be formed by connecting.
The oily nonyl top sealing of hammering is realized by the rubber seal in male top extruding female, due in sealing ring
Side infinite place, when being deformed, easily causes sealing ring damaged.Further, since construction pipeline is more long, the oily nonyl of connection is public
Centering is difficult when head, female, causes its conical surface to be difficult complete gluing, sealing, when tight oil nonyl is pounded, sealing ring can be because of unbalance stress
And damage, also easily cause nut and pound tight illusion, in pipeline pressure-bearing, oily nonyl thorn leakage phenomenon often occurs, cause again
Connecting pipeline and interrupt construction, reduce construction quality, pollute environment.
The content of the invention
In order to overcome the shortcomings of that sealing ring breakage, thorn leakage phenomenon easily occurs in the oily nonyl of existing hammering, the utility model is provided
A kind of oily nonyl of side seal hammering, when the oily nonyl of side seal hammering can avoid cycle operation the oily nonyl of hammering occur sealing ring it is damaged and
Oily nonyl thorn leakage phenomenon, so as to avoid polluting environment, improves construction quality.
The technical solution of the utility model is：A kind of oily nonyl of side seal hammering, including female, male, the female are placed in
Outside male, and the two contact surface is provided with O-ring seal, and the female external screw-thread is connected with locking nut, the male
Outer surface is provided with step, and the step is stuck on the cascaded surface inside locking nut, and locking nut is fitted close with male.
The utility model has the advantages that：Due to taking such scheme, male and both females circumference contact surface
O-ring seal is provided with, O-ring seal is placed in groove, is hardly damaged when being extruded by side；It is public under the guiding of seal head
Head, the conical surface laminating entirely on the center of female, realize effective conical surface seal, finally pound tight locking nut, connect each single pipeline
It is integrated, you can realize the reliable sealing of side seal hammering union junction during cycle operation.Broken so as to avoid the occurrence of sealing ring
Undermine oily nonyl thorn leakage phenomenon, it is to avoid pollution environment, improve construction quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1- females in figure, 2-O type sealing rings, 3- locking nuts, 4- males.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of oily nonyl of side seal hammering, including female 1, male 4, the female 1 are placed in outside male 4,
And the inside of female 1 is provided with O-ring seal 2, when male is connected with female, O-ring seal 2 is limited in groove, is received
Side is hardly damaged when extruding, and realizes side sealing between female 1 and male 4.The external screw-thread of the female 1 is connected with locking screw
Female 3, the outer surface right-hand member of the male 4 is provided with step, and cascaded surface is provided with inside locking nut 3, and the step of the male 4 is stuck in lock
On cascaded surface inside tight nut 3, the axially position of male 4 is realized, and locking nut 3 is fitted close with male 4.
When pipeloop is connected, the side seal is hammered into male 4, the female 1 of oily nonyl respectively to each single to being connected to
On pipeline, by the seal head insertion female 1 of male 4 during docking, now male is realized with the built-in O-ring seal 2 in female
Side seals, while under the guiding of seal head, male, the conical surface laminating entirely on the center of female realize effective conical surface seal,
Tight locking nut 3 is finally pounded, each single pipeline is connected as a single entity, you can realize side seal hammering oily nonyl junction during cycle operation
Reliable sealing.
