Description
Technical field
The present invention relates to a kind of fluid line rapid pipe joint, especially a kind of fluid line rapid pipe joint that is suitable for major diameter connecting conveying pipe road.
Background technique
The installation of fluid-transporting tubing, traditional method is that two metallic conduits are welded, but the equal frame of existing most of fluid line, especially compressed air line is certain high aerial, so generally will take out higher scaffold, the pipeline of needs welding is lifted to after scaffold, the welder who is enriched very much by experience welds again, and this mode not only difficulty of construction is high, long construction period, and in the time of welding, also there is potential safety hazard.In order to address the above problem, Chinese patent literature CN102062271A discloses a kind of connection set of full-diameter compressed air conveying pipeline, this device is made up of metal shell body and seal arrangement, metal shell body is made up of the first hemizonid and the second hemizonid, is provided with locking member and is connected between the first hemizonid and the second hemizonid; The inner chamber of metal shell body is provided with annular mounting groove, and the both sides of annular mounting groove are respectively equipped with annular slope; Seal arrangement is made up of annular frame, two pressure rings and two " O " shape seal rings, two pressure rings are movably set in respectively the both sides of annular frame, pressure ring shoulder is respectively equipped with annular slope, " O " shape seal ring is separately positioned on the corner part of pressure ring inner ring, and two ends of annular frame offset with " O " shape seal ring respectively; And, be provided with annular cambered surface or annular slope is excessive at the corner part of pressure ring inner ring, or be respectively equipped with the 3rd annular slope in the inner side, two ends of annular frame.This sealing device structure complexity, its framework part is divided and is comprised multiple parts, and each parts need out a mold, and its die sinking expense is high and cost of production is high; Parts to be installed also inconveniently, and the skeleton of sealing device is to be all made up of hard material, and sealing only depends on two " O " shape seal rings to realize, in the slightly high occasion of pressure, and the situation that happens occasionally and reveal.
In addition, this connection set at the inner chamber of the outside of described annular mounting groove metal shell body circumferentially continuously or be interval with two location card platforms, is formed for the limited impression of the bulge loop on clamping conveyance conduit between two location card platforms.This connection set is to utilize the seal arrangement being located in annular mounting groove that the joint sealing of two conveyance conduits of needs connection is connected; In order to prevent that pipe under high pressure axially retreating, and depart from connection set body, employing be the limited impression that arranges on metal shell inwall and the mutual clamping of bulge loop on conveyance conduit, locate conveyance conduit.Also there is the problem of the following aspects in the connection set of this structure, the one, the pipeline that conveyance conduit is sold in pipeline processing factory is non-existent, this just needs special device to make in erecting bed, special device input cost is high on the one hand, need on the other hand the technician that experience is enriched very much just can operate out qualified bulge loop, careless slightly, the bulge loop of making is just undesirable, therefore, in the job site with this connection set, can there is a large amount of tube heads with defective bulge loop of being sawed from conveyance conduit, this is also a kind of waste to conveyance conduit, the 2nd, owing to being provided with bulge loop on conveyance conduit, this just makes conveyance conduit when mounted, after need to two and half shells of metal shell being stuck on conveyance conduit, just can locking nut, and this just causes the installation difficulty in the time of narrower space mounting.
Summary of the invention
In order to overcome the problems referred to above, the invention provides the fluid line rapid pipe joint that a kind of cost of production is low, sealing effect is better and easy for installation.
