Specific embodiment
In order to illustrate the embodiments of the present invention more clearly with technical solution in the prior art, Detailed description of the invention will be compareed below
A specific embodiment of the invention.It should be evident that drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing, and obtain other embodiments, the present invention is not restricted to the embodiment.
Please refer to Fig. 1, Fig. 2, Fig. 4, a kind of reinforced biting connecions two-way pipe fitting of the embodiment of the present invention, by upper and lower two and half
1 split of shell is docked, and is equipped with and is docked for the split by upper and lower two half shells 1 and realization will in the half shell 1
It is connected positioned at pipe fitting both ends pipeline or to the occlusion tooth 11 that broken pipe plug leaks, each half shell 1 includes for installing sealing
The seal groove 4 of part 2, the seal groove 4 include axial seal groove portion 41, the first slot circle portion 42 and the second slot circle portion being connected
43；The seal member 2 includes that the axial sealing part 21, first of integrally connected seals half-turn portion 22 and the second sealing half-turn portion
23；The axial sealing part 21 is fitted close with the axial seal groove portion 41, and the first sealing half-turn portion 22 is with described the
One slot circle portion 42 is fitted close, and second sealing half-turn portion 23 is fitted close with the second slot circle portion 43；Described first is close
It is 1 ~ 5mm higher than occlusion tooth 11 after mounting to seal half-turn portion 22 and second sealing half-turn portion 23；21 He of axial sealing part
The joining place that first sealing half-turn portion 22, second seals half-turn portion is equipped with sealing reinforcement structure.
In this example, the sealing reinforcement structure includes 24 He of protrusion for the seal member 2 being installed in one half shell 1
It is installed on the bayonet part 25 of the seal member 2 in another half shell 1；When two half shells 1 up and down for being equipped with seal member 2 are spelled
After closing docking, the protrusion 24 and bayonet part 25 are closely connected.
Among the above, the two union nipples shell is preferably metal shell, but may be plastic shell, to guarantee
Bear certain pressure.Pass through because two union nipples have water flow, if being selected as metal shell, is necessary for stainless conjunction
Gold.It, can also external spray corrosion resistant coating inside the shell in order to reinforce the corrosion resistance of two union nipple shells.
Since seal member 2 and half shell 1 are the structures being separated from each other, so in order to guarantee that seal member 2 can be set to half
In shell 1, be equipped with the seal groove of accommodating seal member 2 inside half shell 1, the size of seal groove should as far as possible with seal member 2
Thickness is identical, is fallen off with placing seal member 2.It, can in order to further strengthen the stability that seal member 2 is connect with half shell 1
To be equipped with multiple fasteners near seal groove, anchor design is the structure that can be dismantled with half shell 1, so as to install additional and
Seal member 2 is dismantled, the fastener is preferably that the mode being spirally connected is connected with half shell 1.
In above structure, the protrusion 24 that 2 corner of seal member is equipped be designed as it is rectangular, if seal member 2 be elasticity
Material, then the tip designs of protrusion 24 are spherical or hemispherical, and spherical or hemisphere portion diameter is greater than projected square part
Length or width, corresponding, 25 penetralia of bayonet on another seal member 2 is set as the spherical shape or hemispherical of corresponding size
Slot, remaining 25 part of bayonet are set as rectangular, and such structure design can guarantee and will not be detached from easily between seal member 2.
In this example, the first sealing half-turn portion 22 at the both ends and axial sealing part 21 form the first leak stopping area, and described the
It is stifled that one sealing half-turn portion 22 and the section surrounded with the second sealing half-turn portion 23 at end and axial seal half-turn portion 21 form second
Drain region preferably prevents leak by the design of two layers of leak stopping circle.
The construction matched using axial direction and annular seal can have better sealing, so that half shell 1 is all arranged
There is the seal member 2 being tightly bonded, and seal member 2 is 1 ~ 5mm higher than occlusion tooth 11, the effect of occlusion tooth 11 is to sting pipe
Firmly, to realize firm connection, the effect of occlusion tooth 11 is actually passed, has been able to the water for stopping a part, but can not
Sealing is formed, water is still easy to leakage；And the design of seal member 2 has then well solved this problem, works as sealing
When part 2 is than occlusion tooth high 1 ~ 5mm, refer to after seal member 2 is installed to designated position, in the radial direction of pipe fitting, sealing
The height of component 2 to the protrusion of pipe fitting central axes is 1 ~ 5mm higher than the height of occlusion tooth 11 to the protrusion of pipe fitting central axes,
In this case, needing two half shells 1 to be pressed since the installation of pipe fitting is fixed, also as seal member 2 is elasticity
Element, therefore after press fitting, the amount of this 1 ~ 5mm is just compressed, so that two half shells are closed with what is formed between pipe
Space still ensures that good leakproofness under stronger water flow pressure, to more preferably ensure that leakproofness, reducing leak can
Energy.
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 half shell 1 is equipped with hole 12, and two 1 through holes 12 of half shell are by being bolted.
Made by the way of being spirally connected between half shell 1 between two half shells 1 detachably, so that in two-way pipe fitting
Portion can dismantle and then be detected at any time after going wrong.
Referring to Fig. 3, being additionally provided with inside the half shell 1 in this example for carrying out water conservancy diversion to water flow, to mitigate turning
Locate the flow-guiding structure 3 of pressure caused by water flow.
In this example, the flow-guiding structure 3 is the projective structure inside half shell 1.
Wherein, the flow-guiding structure 3 may be configured as multiple, and all directions are settable, while in order to guarantee water flow stream
The patency of two union nipples is crossed, the projective structure should not be arranged blocked up, so that projective structure and half shell 1 or protrusion are tied
The distance between structure and projective structure are excessively close, influence the transmission of water flow.
In this example, the both ends of the flow-guiding structure 3 are equipped with extension position limiting structure 32.
Among the above, the extension position limiting structure 32 is outwardly extending protrusion, between the protrusion and half shell 1
With gap, the height in the gap is slightly larger than the thickness of water pipe, so as to accommodate water pipe and be defined to the position of water pipe.
In this example, the extension position limiting structure 32 and 1 interior surface of half shell are constituted to limiting and fixed water pipe
Fixing groove, wherein the gap between extension protrusion described above and half shell 1 is fixing groove.
In this example, the flow-guiding structure 3 is equipped with the diversion trench 31 to guide the flow direction of water flow.
Specific embodiments of the present invention are described in detail above.It should be appreciated that those skilled in the art are without wound
The property made labour, which according to the present invention can conceive, makes many modifications and variations.Therefore, all those skilled in the art
Present inventive concept passes through the available technical solution of logical analysis, reasoning, or a limited experiment in the prior art, all
It should be in protection scope determined by the claims.
