Abstract
The invention consists of upper and lower bodies of pipe connectors, left and right adapters, a radial seal ring disposed between two connecting pipes and an end seal ring disposed between the left side of the right adapter conic step and the right end of the right adapter. In the cavities of the upper and lower bodies of the pipe connectors are disposed slopes corresponding to the left and right adapters conic steps and the upper and lower bodies of the pipe connectors are fastened on the connecting point of the left and right adapters. In the process of fastening the upper and lower bodies of the pipe connectors, the slopes on both sides of their cavities press two conic steps, so as to realize the axial pressure between two adapters. There are both the radial and end seals between the two adapters, so the invention can stop high-pressure liquid and gas from leaking.
Description
Technical field:
The present invention relates to the fluid line sealed connection part.
Background technique:
The fluid line sealed connection part is to be used for the basic link of connecting tube, it is widely used in the delivery line of each class I liquid I, gas, in highly pressurised liquid or gas transfer pipeline, be easy to produce leakage at pipeline junction, leakage is the main cause that causes the delivery line security incident, so the basic demand of convection cell pipeline sealed connection part is: seal reliable, simple in structure, easy to connect, good economy performance.The main structure of fluid line sealed connection part has flange-type, thread type at present, and the pipe coupling that is used for the conveying of air-conditioning system refrigeration agent is mainly thread type, and it has end face seal structure (as accompanying drawing 1) and radial seal structure (as accompanying drawing 2).
End face seal structure: comprise with the left side adapter 3 screwed pipe joint A of fixedlying connected, tighten up nut B, right adapter 4 and end-face seal ring 6, right adapter 4 is sleeved on tightens up in the nut B, in right side adapter 4, suppress step, the front end sleeve of right adapter 4 is in the endoporus of screwed pipe joint A, in the right side of screwed pipe joint A and rightly take over 4 and top bar and be provided with end-face seal ring 6 between the left side, tighten up by tightening up nut B between right adapter 4 and the screwed pipe joint A, make end-face seal ring 6 compressive deformations, thereby reach sealing, leakproof purpose.Its advantage is: simple in structure, easy to connect, double thread pipe joint A, right take over 4, the requirement on machining accuracy that tightens up nut B is not high.Its shortcoming is: end-face seal ring 6 is by tightening up the sealing of nut B compressive deformation, and it is easily loosening at the volley to be threaded, and causes loosening inefficacy of end-face seal ring to produce tiny leakage.
Radial seal structure: comprise screwed pipe joint A, tighten up nut B, rightly take over 4 and radial direction seal ring 5, right adapter 4 is sleeved on tightens up in the nut B, section suppresses seal groove and tightens up step on the left side of right side adapter 4, the front end external diameter of right adapter 4 and the endoporus precision-fit of screwed pipe joint A, take on the right side between the endoporus of 4 front end external diameter and screwed pipe joint A and be provided with radial direction seal ring 5, tighten up by tightening up nut B between screwed pipe joint A and the right adapter 4, seal by radial direction seal ring 5 between screwed pipe joint A and the right adapter 4.Though it is simple in structure, easy to connect, the sealing load that can bear is not high, is easy to generate little seepage, and the requirement on machining accuracy height of each part, and cost of production increases.
Summary of the invention:
The purpose of this invention is to provide a kind of sealed joint of separated assembled fluid pipeline, be specially adapted to the air-conditioning refrigeration system pipeline and connect.
The technical solution used in the present invention is as follows:
Sealed joint of separated assembled fluid pipeline, it connects body, pipe by pipe and connects lower body, left side adapter, right adapter, radial direction seal ring, end-face seal ring and form, take on a left side and the right basic body of taking over is provided with cone step with being connected between the body, a left side is taken over right the adapter and is being connected body section mutual sheathing, between the connection body of taking over about radial direction seal ring is arranged on; End-face seal ring is arranged between the left side and the left right side of taking over of right adapter cone step, pipe connects body and connects between the lower body with pipe and link to each other by the Elastic buckle structure, pipe connect inner chamber that body and pipe connect lower body be provided with rightly take over, a left side takes over the corresponding inclined-plane of cone step, pipe connects body, pipe and connects lower body and be fastened in that a left side is taken over and the right junction of taking over.
Described pipe connects the Elastic buckle structure that body, pipe connect between the lower body: connect the elastic chuck that is provided with evagination on the body at pipe, connect at pipe and be provided with deck on the lower body, offer on deck and be convenient to the elastic chuck hole of location fast.
The sectional shape of described elastic chuck is half " V " type.
Because a left side is taken over right the adapter and both had been provided with radial direction seal ring at linkage section, be provided with end-face seal ring again, a left side take over right adapter between axial compression connect body and pipe by pipe and connect down inclined-plane, intracoelomic cavity both sides and tighten up, when pipe connects body, pipe connects lower body in the clamping process, the cone step that a compressing left side, inclined-plane is taken over and the right side is taken over of its inner chamber both sides, thereby realize the axial seal pressurization between left side adapter and right the adapter, make the sealing of axial sealing ring stress deformation.So just make the double seal that has formed radial seal and end face seal between left side adapter and right the adapter, can stop the leakage of highly pressurised liquid, gas effectively, the tiny leakage of anti-locking system, this structure not only connects simple and convenient, and the reliability height of sealing, its characteristics:
1. connection body and the type conical bench owing to left side adapter right-hand member obtained by plastic deformation processing method by basic body, this structure can be finished with Mould Machining is disposable on pipe end forming machine, need not welding, be suitable for again producing in batches, and the quality of processing of part is guaranteed that reliably cost reduces.
2. a left side take over right the adapter between be connected and need not with screwed pipe joint and tighten up nut, not only saved metallic material, realized having eliminated screwed pipe joint and the leakage phenomenon that tightens up between the nut because of generation after becoming flexible to mould cash equivalent, the more important thing is.
The pipeline that this separate assembling seal for pipe joints joint is specially adapted to all kinds of fluids such as the refrigeration pipe, natural gas, oil, chemical industry of civilian and car air-conditioner is carried and is connected.
