Specific embodiment

In order to illustrate more clearly of the utility model embodiment and technical solution in the prior art, attached drawing will be compareed below Illustrate specific embodiment of the present utility model.It should be evident that the accompanying drawings in the following description is only the one of the utility model A little embodiments for those of ordinary skill in the art without creative efforts, can also be according to these Attached drawing obtains other attached drawings, and obtains other embodiments, and the utility model is not restricted to the embodiment.

Please refer to Fig. 1, Fig. 2 and Fig. 3, a kind of shock resistance type multiple way union of the utility model embodiment, by two half-shells 1 split of body is docked, and is equipped with and is docked for the split by two half shells 1 and pipe will be located at by realizing in the half shell 1 The linking of each end pipe road of connector or occlusion tooth 11 to the leakage of broken pipe plug, the seal groove including being set to 1 internal edge of half shell, for pair The locating part 4 and seal member 2 that water pipe is limited, the seal groove include the axial direction being set to inside half shell 1 being connected The arcuation for sealing groove portion and nozzle edge seals groove portion, and the seal member 2 includes the axial sealing part 22 and arc being integrally connected Shape sealing 21, the axial sealing part 22 being set in axial seal grooves tightly, the arcuation sealing 21 being set to tightly In arcuation seal groove, the arcuation sealing 21 is 1-5mm higher than occlusion tooth 11 after mounting；The locating part 4 is set on each pipe Mouth intersection edge and the projection piece for being higher than occlusion tooth 1-3mm.

Wherein, the arcuation sealing 21 is the arc seal member positioned at passway position, the axial sealing part 22 It is the axial seal component inside half shell 1.

In above structure, more union nipple shells are preferably the biggish place of unoxidizable alloy shell, especially hydraulic pressure, There is biggish pressure to shell, therefore the biggish place of hydraulic pressure uses metal shell as far as possible.Certainly, little in some hydraulic pressure Place, shell can choose plastic material, while in order to improve the corrosion resistance of pipe fitting shell, can also be outer inside the shell Portion sprays corrosion resistant coating.

So in order to guarantee that seal member 2 can be firmly stuck in multi-pass pipe half shell 1, and the size and sealing of seal groove The size of component 2 is identical or the size of seal groove is bigger.It is firm in order to further strengthen that seal member 2 connect with half shell 1 Property, sealing groove edge can also be equipped with fixing piece, the turnable side for being connected to seal groove in described fixing piece one end, and the other end can spiral shell It is connected to the other side of seal groove, so as to effectively prevent seal member 2 from falling off.

In this example, it is arc that the seal member 2, which is placed in turning, and the seal member 2 at the turning is equipped with and prevents Leak reinforcement part 23.

Wherein preventing water leakage reinforcement part 23 is also unsuitable wide, in order to avoid influence water outlet

Preferably, the arcuation sealing 21 include the first arcuation sealing 211 and the second arcuation sealing 212, first The region that arcuation sealing 211 and axial sealing part 22 surround forms the first leak stopping area, the first arcuation sealing 211 and the second arc Shape sealing 212, axial sealing part 22 form the second leak stopping area.

Construction using the double-deck leak stopping area can have better sealing, prevent even if the first leak stopping area from blocking up completely Leakage is ensured there are also the second leak stopping area as second again.

In this example, the first arcuation sealing 21 1 position of half shell corresponding with the junction of axial sealing part 22 is set There is an interconnecting piece 12, corresponding 1 position of half shell in the water flow turning also is provided with interconnecting piece 12.

In this example, the seal member 2 is rubber packing element 2.

It can guarantee the impact resistance of seal member 2 using rubber packing element 2, and can tightly be fitted in outside water pipe On wall, to ensure that leakproofness.

In this example, the interconnecting piece 12 is equipped with hole 121, and two 1 through holes 121 of half shell are by being bolted.

It is preferable provided with threaded hole on two half shells 1, is to carry out spiral shell to two shells using screw rod equipped with threaded hole It connects, and is adjustable the tightness of fitting, but also two half shells 1 can be dismantled at any time, so that inside multiple way union Multiple way union can be dismantled after going wrong and is checked.Above-mentioned only one of connection type, also can be used with lower section Formula is attached, for example threaded hole is not set in two half shells 1, and two half shells 1 are spirally connected by two fasteners oppresses half shell 1 tightly The mode of fitting is attached, and the fastener is arc strip structure that is arc-shaped and being bonded multi-pass pipe shell wall, is being fastened The both ends of part are equipped with the joint face of sheet, and the joint face is equipped with threaded hole, is attached by screw rod to fastener, In, fastener can also can be the even number beyond two not just for two.

It further include pivoting leaf in this example, the pivoting leaf 3 is set to the centre of each passway intersection or multiple way union Place, sheds the impact force of water flow by the rotation of pivoting leaf 3, to reduce water flow to the pressure of outer shell walls.

Meanwhile in order to avoid water pipe access multiple way union it is too deep so that between water pipe abut or casing, multiple way union The settable locating part 4 for backstop water pipe in inside, wherein the projection piece 41 can be set to inside multiple way union away from The protrusion of 3 certain distance of pivoting leaf, unsuitable excessively high, the height energy backstop water pipe of protrusion, wherein arcuation stop part 42 Also unsuitable wide, in order to avoid influence water outlet.

Preferably, the pivoting leaf 3 includes fixed column 33, bearing 32, flabellum 31, and the fixed column 33 is to by pivoting leaf 3 are fixed on the inside of multiple way union, and the bearing 32 is to be connected and fixed column 33 and flabellum 31.

In above structure, 33 both ends of fixed column are fixed on the shell wall inside multiple way union, and welding can be directly used Mode fixed column 33 is welded on inside the half shell 1 of multiple way union, but disadvantage of this is that can not again will rotation Leaf 3 removes inside half shell 1.Certainly, dismountable mode can also be used pivoting leaf 3 is fixed in inside half shell 1, For example, being spirally connected, but need to do half shell 1 and pivoting leaf 3 improvement of a point structure in this way, 1 inside of half shell and fixed column 33 junction needs to add threaded hole, and the both ends of fixed column 33 are also required to add spiro connecting piece, and preferably sheet spiro connecting piece.

In above-mentioned 3 structure of pivoting leaf, the effect of bearing 32 is so that flabellum 31 not will drive fixation while rotation Column 33.

Preferably, the quantity of the flabellum 31 is 4.

Wherein, if the quantity of flabellum 31 is 1 to 2, and the position that is in of flabellum 31 or angle be not right, then passes through pivoting leaf 3 rotation shed water flow impact force will necessarily bad or even flabellum 31 will not all rotate.And according to the rotation of 4 flabellums 31 3 structure of leaf, the then impact that can have flabellum 31 that can afford water flow, to drive the rotation of flabellum 31.Certainly, using 4 flabellums 31 or more structure is also possible, but can improve cost in this way and seem that some are extra.

Preferably, the flabellum 31 is high-strength corrosion-resisting flabellum 31, so as to bear the impact of water flow.

Specific embodiment of the utility model is described in detail above.It should be appreciated that those skilled in the art without It needs creative work according to the present utility model can conceive and makes many modifications and variations.Therefore, all the art Technical staff's the utility model design is available by logical analysis, reasoning, or a limited experiment in the prior art Technical solution, all should be in protection scope determined by the claims.
