Description

A kind of dismountable uniform internal diameter pipe joint
Technical field
The utility model is a kind of dismountable uniform internal diameter pipe joint, is widely used in the gas in the fields such as Aero-Space, communications and transportation, petrochemical industry, electric power system, liquid transmission pipeline field.
Background technique
Existing pipe joint structure, disclosed in CN202100849U " linkage structure of spinning pipe fitting ", its structure is by pipe joint, pipe and attaching nut are formed, the outer end inner ring of described pipe joint is provided with internal thread, the outer ring of attaching nut is provided with the outside thread matched with internal thread, attaching nut is screwed in pipe joint, described pipe is plugged in pipe joint through attaching nut, the outer ring, end of pipe is provided with annular protrusion, end and the described annular protrusion of attaching nut offset, circular groove is provided with in the outside of annular protrusion, O RunddichtringO is provided with in circular groove, and be provided with the first annular slope at the inner ring of pipe joint, O RunddichtringO and the first annular slope offset.
The O RunddichtringO structure that it adopts, makes connecting tube internal diameter have contraction position, causes whole connecting tube joint to have the generation of turbulent phenomenon when in use.
For another example CN201152409Y disclosed " metal framework reinforced plastic composite pipe network ", its specific design scheme comprises: the inner layer sleeve having band boss, in inner layer sleeve, at least excircle is connected with the inner plastic melting of metal skeleton reinforced composite plastic pipeline end, pipe joint is connected with the plastic outer layer of metal skeleton reinforced composite plastic pipeline end and the boss outer peripheral surface melting of inner layer sleeve, pipe joint and inner layer sleeve melting connect as one and form an annular U type joint socket, annular U type joint socket by the plastic outer layer of metal skeleton reinforced composite plastic pipeline termination and inner plastic and the complete melting of pipeline end face coated, multiple tube is connected by pipe joint with multiple tube and forms pipe network.
The problem of this technological scheme is, after its inner layer sleeve (drawing reference numeral 1) is connected with the pipe joint at two ends, the internal diameter of inner layer sleeve is less than the internal diameter of pipe joint, define the rapid shrinking structure of internal diameter of the pipeline, after pipeline is connected, internal diameter is discontinuous, easily causes turbulent flow, increases the pressure of pipe interior, bring higher requirement to the bearing capacity of sealing and pipeline, easily bring pipeline burst and leakage.
For another example CN101248305B disclosed " pipe coupling ", its specific design scheme comprises: the holding element with sharp-pointed pipeline press-in edge, this press-in edge provides the sealing between tube gripping member and pipeline.Another kind of such joint comprises the tube gripping member with fittings body press-in edge, and this press-in edge provides the sealing between tube gripping member and fittings body.
The problem of this technological scheme is, pipeline interface organization is complicated, and inner caliber also exists contracting position suddenly, so also there is the problem of turbulent flow, pressure-bearing and sealing.
So based on foregoing, designing a kind of sealing configuration good, the connecting duct that tube wall resistance is little, is the technical problems to be solved in the utility model.
