Description
The present invention is about the fluid conduit coupling apparatus of quick connection, and wherein, a fluid conduit systems is connected on another fluid conduit systems of using in joint, valve and other member with not leaking.More particularly, the present invention is a kind of improved clamping ring, and it can be slidingly attached in another fluid conduit systems a tubular conduit, and as long as from second tubular conduit is stubborn outward first fluid coupling is dismantled.
United States Patent (USP) NO.4390159 discloses multiple valve and tubular conduit piecing devices, wherein, one has the split type clamping ring of sharp keen radially internal tooth can load onto this conduit slidably when a tubular conduit axially inserts, only need locking or keep this tubular conduit, make its not along linear axis to withdrawal backwardly, and dismantling of tubular conduit can realize by the tubular conduit that turns insertion with respect to clamping ring towards the other places.The advantage of this piecing devices be without instrument with just can carry out liquid-tight the connection with the minimum time.When it clamped the tubular conduit of insertion tightly in the no leakage mode, it just had another additional advantage, promptly need not destroy the clamping tooth tubular configured joint of insertion is backed out.Therefore, if tubular conduit has the crack or when needing repairing, needn't destroy whole piecing devices, only need unscrew the pipe joint of insertion, with new pipe joint it be replaced just passablely, if necessary, conduit can unload in replacement process, with repeated use.
The pipe joint that the purpose of Fa Benming provides a kind of low price, easily assembles.
Another object of the present invention provides a kind of improved clamping ring that supplies pipe joint to use.
The present invention consists essentially of an interior garden cylinder on first pipe fitting, the outer garden cylinder of a garden cylinder in the diameter on second pipe fitting is slightly smaller than on first pipe fitting, the device that connects the inside and outside garden post of above-mentioned first pipe fitting and second pipe fitting hermetically, and
Also comprise in the interior garden cylinder that is installed in above-mentioned first pipe fitting, pin the clamping device of the outer garden cylinder of above-mentioned second pipe fitting removably.Above-mentioned clamping device have a plurality of radial in the inside around the spaced tooth in ground, these teeth have sharp-pointed radially inner edge, these teeth radially inwardly and along one substantially the planar axes of taper to extending frontward, each tooth has reversing a little along common direction, thereby when axially inserting, the conical surface direction of polymerization of above-mentioned tooth can slip over above-mentioned tooth when second pipe fitting, as long as above-mentioned relatively tooth is unscrewed second pipe fitting and just can be dismantled, and can not destroy tooth.
In one embodiment, this clamping device is contained in the valve body; In another embodiment, this clamping device is to be contained in the joints such as connecting two tubular conduits or bridge piece.
Fig. 1 is an expression valve body profile of the present invention;
Figure 1A is the local detail of valve body shown in Figure 1;
Fig. 2 is a cross-sectional view taken shown in Figure 3;
Fig. 3 is the profile of the typical joint of expression theme of the present invention;
Fig. 4 is the part sectioned view that obtains along the 4_4 line on Fig. 2;
Fig. 5 is the sketch map of the sort of typical joint shown in Figure 3.
As Fig. 2 and 3 clearly shown in, joint 10 has the shell 12 of a garden cylindricality, it has one to determine post surface, interior garden 14 and the centre bore that stops at interior shoulder 16 places, with interior shoulder an improved clamping ring 18 is being set relatively, it has a plurality of radially inwardly teeth that end at sharpened edge 21 20.
As Fig. 2 and 4 clearly shown in, clamp a successive garden cylindricality ring, it has as Fig. 4 shown in " B " approximately is the tooth 20 that the angles of 30 degree axially curve towards the astringent conical surface by letter, each tooth has additional reversing on common direction, thereby with regard to shown in reference mark on Fig. 4 " A ", the most forward edge of each tooth is curved into 33 degree angles.When tubular conduit is inserted
When going into the left side to Fig. 2 and 4, this taper of above-mentioned tooth and reverse configuration and make tubular conduit can slip over the sharpened edge of tooth 21, if and tubular conduit such as Fig. 2 and 4 withdraw point-blank, these teeth will bite in the tubular conduit, thereby tubular conduit just securely installs to 14 li on interior garden cylinder.Yet tubular conduit can be by turning tubular conduit outwardly, is accompanied by the line that tooth carves and unloads on tube material.Like this, if necessary, the part of conduit is unscrewed with respect to another part, conduit just can successfully unload, but will be maintained fixed together by the tooth of clamping ring in normal operation.Firm clamping ring can contrast with the clamping ring shown in the United States Patent (USP) 4390159, the scope of that part patent concentrates on all styles of that covers clamping ring, and can unscrew by the firm or discontinuous conduit that makes that this embodiment of the present invention represents, a kind of improved spiral unloading is provided, and is to realize this point by reversing of tooth on the clamping ring.
Except clamping ring 18, against clamping ring a sleeve pipe 24 is being set also, clamping ring is leaned against on the interior shoulder 16 securely.Against sleeve pipe 24 an O RunddichtringO 26 is being set, then, end sleeve pipe 28 is buckled on the tube-like envelope 12 and the measure that is fastened on the outer faucal with ultra-sonic welded or other end sleeve pipe maintains it.The inner of end sleeve pipe 28 leans against on the O RunddichtringO and to its pressurization, it radially outward and is inwards expanded, thereby between the post surface, outer garden 31 on the interior garden of shell 12 post surface 14 and the interior tubular conduit 32, form liquid-tight sealing, 38 expression ultrasonic bond seams.
Fig. 3 represents joint shown in Figure 2 with above-mentioned same numeral with profile.
As shown in Figure 1, these piecing devices can be implemented in valve body 40, this valve body has an outer garden cylindrical shell 42, it stops at shoulder 16, and remainder has O RunddichtringO 26 shown in Fig. 1 and 1A, clamping ring 18, by end sleeve pipe 28 sleeve pipe 24 is contained in its inside, otch 25 bridle joint flanges 27 are in case sleeve pipe rotates.
And valve rod 50 and a valve member 54 that valve body shown in Figure 1 also has one one end to stop with executive component 52, valve member has " O " circle that is contained on the valve seat 58.An auxiliary gateway 60 is connected on the valve body.The executive component 52 of valve is provided with inner surface 70, and it is placed on the wrench 72, catches valve, one auxiliary " O " circle 76 against the valve seal valve rod, in case liquid flows out around valve rod on the release position that valve member 54 is opened.
When most preferred embodiment of the present invention has been expressed and has illustrated, should be understood that concerning those skilled in the art of the present technique, do not break away from theme of the present invention and can make various changes, so the present invention is not limited to the specific embodiments shown in the accompanying drawing.
