Description
Technical Field
The utility model belongs to the pipe connection spare field, concretely relates to sealed natural gas line insulated joint.
Background
The natural gas pipeline is a pipeline for transporting natural gas, including associated gas produced in oil fields, from a mining place or a processing plant to a city gas distribution center or an industrial enterprise user, and is also called a gas transmission pipeline. The natural gas pipeline is used for conveying natural gas, and is the only way for conveying natural gas on land in large quantities. In the total length of pipelines in the world, natural gas pipelines account for about half, and gas pipelines are assembled by connecting single pipes one by one. Modern gas collection pipelines and gas transmission pipelines are formed by connecting steel pipes through electric welding. The steel pipe has various types, such as a seamless pipe, a spiral seam pipe and a straight seam pipe, the seamless pipe is suitable for a pipeline with the pipe diameter of less than 529 mm, and the spiral seam pipe and the straight seam pipe are suitable for a large-diameter pipeline. The pipe cross section structure of the gathering and transportation pipeline is complexly an inner coating, a steel pipe, an outer insulating layer and a heat preservation (cold insulation) layer; simple then only steel pipe and outer insulating layer, and inner wall coating and heat preservation (cold insulation) layer are all looked gas transmission technology and are confirmed again, because gas transmission pipeline is for compriseing the multistage pipeline, and communicate each other and formed intensive gas net, so its leakproofness is just especially important, because natural gas mainly used people family life uses, the personal safety of people is related to, cause great trouble after the pipeline reveals easily, and the revealing of gas transmission pipeline is mostly revealing of connector department, and simultaneously, in some regions of just installing the gas, owing to can not use and cause the gas tempering easily, arouse the explosion easily.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a leakproofness is good, can prevent that the gas from tempering, increases the high sealed natural gas line insulated joint of security.
In order to realize the purpose, the utility model discloses a technical scheme be, a high sealed natural gas line insulated joint, including connector and connecting body, the connector is established at connecting body's both ends, and its structural feature is, and the connector includes inner joint and outer joint, is equipped with the cavity in the outer joint, and the outer joint adopts elastic rubber to make, connecting body in be equipped with solid fixed ring, gu be equipped with the baffle on the fixed ring, the one end and the solid fixed ring movable seal of baffle are connected, the other end passes through the aluminium metal wire and connects on the inner wall of connector body, the baffle be the several, form a circular closing plate when several baffle plane annular array.
As a further improvement, the utility model is provided with a magnet on each baffle, the baffles are even numbers, and the magnets on two adjacent baffles attract each other.
As a further improvement of the utility model, the baffle is provided with a sealing gasket, and the movable angle of the baffle is 30-90 degrees.
As a further improvement of the utility model, the baffle is an alumina ceramic plate.
As a further improvement of the utility model, the outer joint is provided with a gas injection port which is the same as the cavity, and the gas injection port is provided with a sealing cover.
The utility model has the advantages that: reasonable in design, simple structure, the leakproofness is good, can prevent the gas tempering, increases the security to it is comparatively convenient to install and dismantle.
Drawings
Fig. 1 is a schematic view of the structure of the present invention;
fig. 2 is a left side view structure diagram of the present invention;
the connecting structure comprises a connector 1, a connecting body 2, an inner connector 3, an outer connector 4, a fixing ring 5, a baffle 6, an air injection port 7 and a sealing cover 8.
Detailed Description
The invention is further explained with reference to the drawings, without limiting the scope of protection of the invention.
As shown in fig. 1-2, a high sealed natural gas line insulated joint, including connector 1 and connecting body 2, connector 1 establishes at the both ends of connecting body 2, connector 1 include inner joint 3 and outer joint 4, be equipped with the cavity in the outer joint 4, outer joint 4 adopts elastic rubber to make, connecting body 2 in be equipped with solid fixed ring 5, gu be equipped with baffle 6 on the fixed ring 5, the one end and the solid fixed ring 5 swing joint of baffle 6, the other end passes through the aluminium metal wire and connects on the inner wall of connector body 2, baffle 6 be the several, form a circular closing plate when 6 planar ring array of several baffles.
Each baffle 6 is provided with a magnet, the baffles 6 are even, and the magnets on two adjacent baffles 6 attract each other; the baffle 6 is provided with a sealing gasket, and the movable angle of the baffle 6 is 30-90 degrees.
The baffle 6 is an alumina ceramic plate; the outer joint 4 is provided with a gas injection port 7 which is the same as the cavity, and the gas injection port 7 is provided with a sealing cover 8.
The utility model discloses when specifically using, can be earlier with nipple 3 and pipe connection, press from both sides the pipeline in the centre through outer joint 4 and nipple 3, can inflate in the accessible gas injection mouth 7 outside joint 4 this moment, make outer joint 4 take place the inflation, thereby form completely sealed, and when the gas in the pipeline takes place the tempering, can take place the inflation because the heat is great, thereby make aluminium metal silk fracture, because be equipped with sealed the pad on baffle 6, and baffle 6's activity angle is 30-90 degrees, form a circular closing plate when 6 plane ring arrays of several baffles, so can be timely block the gas in the pipeline, prevent the danger of taking place continuous explosion.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
