Description
Technical field
The present invention relates to pipe joint, particularly a kind of direct insertion slip-knot Fast-mounting tube fitting.
Background technique
Existing direct insertion pipe fitting, directly inserts body 6 by tubing 5 when installing as shown in Figure 9, and one is slotting all right.The performances such as its installation is reliable, quick, foolproof installation are all better than legacy card shell type connection pipe fitting in every respect, are widely used gradually all over the world.
Existing direct insertion pipe fitting, as Fig. 9,10, shown in 11 and 12, comprise integrated body 6, be arranged on the spacing ladder annular groove 61 of projection of body 6 stage casing madial wall, the parent socket port got pipe ring circle 8 or get pipe box cylinder 51 and socket-connect with it of body 6 two-port, it has some limitations in actual applications:
1, as shown in Fig. 9,10, after direct insertion pipe fitting is connected with tubing 5, occur using length to have mistake, when needing dismounting, after needing first to compress and move back pipeloop overhead snap ring with the assistant tool such as hand or plastic card king 7 in port, to pull back again tubing 5, compress port by the dynamics of finger, because unbalance stress can cause the latch off normal of snap ring, very easily cause tubing 5 to dismantle, not only require great effort, and tubing 5 is easily scratched by the latch of snap ring.If service time is excessively of a specified duration, the latch of snap ring is bumped into tubing 5 too deeply by hydraulic pressure, the dynamics that only armrest refers to tubing 5 cannot be dismantled smoothly.Again as shown in figure 11, what another integrated auxiliary ring gets pipe ring circle 8, though economized the assistant tool getting pipe, can practical effect is the same, tubing 5 is equally easily scratched, and not only wastes tubing 5, and work during waste.
2, the snap ring of direct insertion pipe fitting, because needing enough elastic force and toughness, mostly be the metal material such as stainless steel or copper, because extruding pipe port with assistant tools such as hand or plastic card kings during connection, can not comprehensive uniform force, generally do not go extruding, so the tubing of plastics is insert body by force substantially, be easy to be scratched by the latch of snap ring, cause drip, leak.Repeatedly using of body and tubing, scratches and leaks just even more serious, causing unnecessary loss, strengthen cost.
3, the bore of direct insertion pipe fitting at present maximum accomplish ф 32 because bore does large, tubing because of the elastic force of snap ring increase and increase after mutual resistance and cannot insert smoothly, inserting by force more can scratch tubing, causes to drip, leak.And assembling and dismounting time, palm and the strength size of people are limited, stressed cannot uniformity, also without suitable dress, dismantle assistant tool, tubing cannot be disassembled, pipe fitting does not quite, can not meet the demand in market.
4, existing direct insertion pipe fitting, as shown in Figure 9, direct insertion pipe fittings all at present is all provided with protruding spacing ladder annular groove 61 at body 6 stage casing madial wall, because of arrange by self limit or too much affect it and connect effect for preventing tubing 5 from inserting body 6 and establish, thus by the restriction of protruding spacing ladder annular groove 61, direct insertion pipe fitting can only play the effect connecting tubing 5, cannot accomplish overall for tubing 5 through, slip-knot can not be done use, be not easy to maintenance operation.Compared with hot melt pipe fitting, do not have many advantages, its economy and practicability are also therefore limited, so sales volume and market are all little.
5, existing direct insertion pipe fitting, as as shown in Figure 10, Figure 11, suppose that body 6 stage casing madial wall does not arrange the spacing ladder annular groove 61 of projection in Fig. 9, but the pipe box cylinder 8 of getting at two hand each overhead body 6 two ends all must be needed snap ring to be opened and can not loose one's grip, thus another staff is wanted to take tubing 5 to go to run through body 6, body 6 is more all the more so, perhaps must add staff.Loose one's grip in any one end of body 6, because card loopback card tubing 5 all can make tubing 5 be scratched when running through pipe fitting.Even if so body 6 can be through, be also not suitable for doing slip-knot and use, be not easy to maintenance operation, not only time-consuming, effort also waste of manpower, is badly in need of the necessity having improvement.
6, existing direct insertion pipe fitting jointing pipe material is without the need to hot melt, viscose glue, does not also need this characteristic of implement instrument, accounts for certain advantage in high-altitude assembling and field-strip.But what all need to go to overhead body two ends with very large hand-power because of assembling and dismounting gets pipe ring circle, and a lot of situation next people cannot operate.Therefore the restriction being subject to high-altitude or space and the restriction self arranged, fulfil assignment also inconvenient, quick, so applicability neither be very large.
7, existing direct insertion pipe fitting cannot connect and state's dimensioning tubing devious, such as ф 25 pipe fitting limits so can only connect ф 25 tubing by self norms bore, tubing bigger than normal cannot insert connection, because only having the single locking and positioning of snap ring after tubing less than normal connects, tubing can comprehensively rock, cause drip, leak.And the bore majority of tubing in all parts of the country all exists certain difference with state's dimensioning is large and small, so can not meet the demand of most client, therefore its economy and practicability are also limited to, and thus do not have commercioganic competitive ability.
8, patent ZL2012204065707 " a kind of direct insertion slip-knot Fast-mounting tube fitting ", as shown in Figure 12, what the band outside thread arranged in its pipe fitting was integrated gets pipe box cylinder 51, although lead to locate the degree of opening promoting snap ring by rotating, but the way of propelling of screw thread rotation, the promotion cone-tip surface 52 getting pipe box cylinder 51 front end can be made easily to be scraped breach by the latch of snap ring, breach is once snap in the latch of snap ring, easily cause both dual damages, cause pipe fitting to use, thus also have much room for improvement.
