Abstract
The utility model relates to a ground high-pressure pipeline connector used for thick oil thermal collecting process, comprising a male joint 1, a female joint 2 and a locking rear cap 3 which are interconnected with ball surfaces. Thus, the sealing action of the connector is realized. The fast connection is realized through the locking rear cap 3 and the female joint 2 connected by a T-shaped fastener with a big thread pitch. The locking rear cap 3 is hollowly sheathed with the male joint 1 for providing a certain rotating space for the male joint 1. The eccentricity of pipelines can be regulated automatically. The high-pressure self-regulating pipeline connector has the advantages of brief structure, convenient and fast installation and safe operation. The high-pressure self-regulating pipeline connector not only can be used for air injection pipelines in the thermal collecting process, but also can be used for the connections of high-pressure pipelines of production well, oil transportation, water injection, etc.
Description
Technical field:
The utility model relates to a kind of ground high pressure line connection set that is used for the hot extracting thick oil engineering.
Background technique:
At present, in the hot extracting thick oil process, the clip connected mode is adopted in the connection of ground steam injection pipeline.There are four kinds of drawbacks in this Placement: the one, and annex is many, operation inconvenience, adopt this kind connection, one place needs two clip heads, one pair of slips, a gasket ring and four fastening screws, along with different oil wells are annotated vapour, need often to pipeline dismounting and replacing, because accessory is many, cause the dismounting trouble, and labor intensity is big; The 2nd, sealing effect is bad, and this kind is connected to and is rigidly connected, because can not desirable centering between the pipeline, causes between clip head and the gasket ring sealing effect bad, and leakage phenomenon happens occasionally; The 3rd, the cost height, along with the continuous dismounting displacement of pipeline, accessory is changed frequent, adds and leaks the construction that repeats that causes, and cost is increased; The 4th, there is potential safety hazard, because what pass through is high temperature and high pressure steam in the pipeline, very easily cause the fastening screw corrosion, and need use the sledgehammer hammering during dismounting, security incident very easily appears, personal safety constituted a serious threat.
Summary of the invention:
The purpose of this utility model is to provide a kind of and can the defective that misaligns between the high pressure steam injection pipeline be realized regulating automatically, thereby can guarantee the high pressure self-regulation surface line connector of easy for installation, sealing effect and construction safety.
The utility model is to realize like this.This kind pipe connector adopts inside and outside spherical surface closely to contact, can both guarantee at an arbitrary position the design principle that seals, realizes misaligning the defective function of compensation automatically between the pipeline, thereby reaches best sealing effect.This device is made up of tool joint pin, female joint, locking back of the body cap, links the mode of connecing by locking back of the body cap and female joint with large screw pitch T type between the three and links together, and can realize the quick connection of ground steam injection pipeline; Simultaneously, dock with sphere between the three, thus the seal action of realization connector; In addition, lock back of the body cap sky and be enclosed within the tool joint pin, make tool joint pin that the rotation space of certain limit be arranged, can misalign defective to pipeline and compensate automatically, thereby reach the optimum efficiency of sealing.
The utlity model has following advantage: 1, compact structure, easy to connect; 2, annex is few, and expense is low, can be repeatedly used; 3, the defective that misaligns that forms between the pipeline is had automatic compensation function in installation process, thereby can avoid because of the poorly sealed steam leakage that causes; 4, reduce labor strength.This device is easy for installation, quick, safe and reliable, not only can be used for the thermal recovery steam injection pipeline in the thick oil well steam injection process, and can be applicable to the connection of oil recovery well, oil transportation, water filling and other high pressure line.
Description of drawings:
Fig. 1 is a general structure schematic representation of the present utility model, and Fig. 2 is its side view.
Embodiment: enforcement of the present utility model is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of tool joint pin 1, female joint 2 and locking back of the body cap 3, material is 35CrMo, its structure, assembled relation are as follows: tool joint pin 1 front end sphere places in the female joint 2 inner spheres, the two joint the other ends link to each other with pipeline with tubing round thread respectively, locking back of the body cap 3 skies are enclosed within tool joint pin 1 outside, and buckle with the T type with female joint 2 and to be connected, and sphere is compressed.Wherein, tool joint pin 1 one sides are processed with the outer spherical surface at two intervals, and wherein the sphere of front end and female joint 2 inner ball surface match, and another sphere matches with locking back of the body cap 3 inner ball surface, and tool joint pin 1 opposite side is provided with button in the plain end oil well pipe, in order to be connected with pipeline.Female joint 2 one ends are processed into inner ball surface, and the outside is straight and be provided with lock back of the body cap 3 is connected with large screw pitch T type and buckles outward, and the other end is provided with that plain end oil well pipe is interior detains.Locking back of the body cap 3 is a circle body, and its periphery is uniformly distributed with 4 protrusion round platforms along the circumference, and inner headed face is processed with respectively in the inner ball surface that matches with tool joint pin 1 sphere and the large screw pitch T type that is connected with female joint 2 and buckles.
