By using technique scheme, the technique effect that this utility model is reached is: expand neck by two The setting in chamber, then expands neck chamber to two and carries out corresponding design optimization, improve the structure of itself, utilize Steel ball keeper and the design of little steel ball, use simultaneously wavy spring with the use of so that this product energy Enough effective guarantees service life, and can quickly patch and dismantle during facilitating product life-time service, Ensure that again during quick jacket pipes, body will not cause scuffing and sealing go wrong Phenomenon, improve work efficiency, it is to avoid unnecessary potential safety hazard.

Accompanying drawing explanation

Below in conjunction with the accompanying drawings this utility model is described in further detail.

Fig. 1 is broken section structural principle schematic diagram of the present utility model.

Detailed description of the invention

With reference to Fig. 1, a kind of Double seal ring Quick joinker for pipeline disclosed in this utility model, body 10 is extremely The expansion the most laterally of few Single port forms the first expansion neck chamber 11, and first expands neck chamber 11 expands formation the most laterally Second expands neck chamber 12, and the second port expanding neck chamber 12 forms choke 1 to contract, and first expands neck chamber 11 to the second are expanded and are connected by changeover portion 14 between neck chambeies 12, changeover portion 14 to choke 13 direction by interior Outward-dipping.It is provided with the sealing ring 15 of two equal diameters, in first expansion neck chamber 10 between two sealing rings preferably Mutually become placed against, it is of course possible to expand neck intracavity first and the seal groove at two intervals is set, the most each close Sealing groove is correspondingly arranged a sealing ring, and the internal diameter that the external diameter of sealing ring 15 and first expands neck chamber 10 is equal, interior Footpath is less than the internal diameter of body 10.So can effectively strengthen sealing property when pipe fitting patches, will not go out easily The phenomenon now leaked, and decrease snap joint because of abrasion the chance got rusty, enhance service life. Second expands in neck chamber 12 and is provided with lock tube 23, and lock tube 23 port corresponding with choke 1 is to contract shape Becoming choke two, choke two is provided with bulge loop 24, and bulge loop 24 stretches out outside choke 1, in lock tube 23 Wavy spring 16, steel ball keeper 17 and by spacing the unloading of choke two it is sequentially provided with to choke two direction Set 18, the sidewall of steel ball keeper 17 is uniformly distributed with along the circumference several through holes, is equipped with little in each through hole Steel ball 19, it is generally the case that in order to prevent little steel ball from inwardly dropping, can by side bore inner for through hole slightly Micro-little compared with outer side, i.e. through hole aperture on steel ball keeper 17 medial wall is less than on lateral wall Aperture, through hole aperture on steel ball keeper 17 lateral wall less than the diameter of little steel ball 19, through hole interior Cavity wall is the concave spherical surface of annular.

In order to strengthen the wavy spring 16 of inside, steel ball keeper 17 and unload the close-fitting relationship of set 18, And service efficiency, advantage in terms of service life, the medial wall of lock tube 23 is first straight to choke two direction The equal diameter chamber 20 in footpath, being the reducing chamber 21 of reduced diameter again, wherein wavy spring 16 is located at directly In chamber, footpath 20, steel ball keeper 17 is located in reducing chamber 21.Certainly, under this design, unloading set 18 is The straight sleeve that choke two is outer, one end is positioned at lock tube 23 is exposed in one end, and straight sleeve is positioned at lock tube 23 Side outward flanging forms turn-up portion 22, and this turn-up portion 22 is spacing by choke two.Wherein, lock tube 23 The lateral wall of choke two is adjacent to the medial wall of choke 1.In this scheme, so that patch and tear open The effect unloaded is higher, is provided with pad 25 (material near the first side expanding neck chamber 10 in second expands neck chamber 12 Material does not limits, but preferentially selects the pad of stainless steel material), the lateral wall of pad 25 is adjacent to the second expansion The internal chamber wall in neck chamber 12, pad 25 is arranged between lock tube 23 and changeover portion 14.Here pad 25 is interior Footpath should be not more than the internal diameter of body 10.

In such scheme, body 10 is concaved with near the first side expanding neck chamber 11 limit of annular Position groove 26, limited impression 26 can effectively limit the length that pipe fitting inserts.The outside of steel ball keeper 17 Wall is to unloading the set 18 diminishing inclined planes of orient diameter by wavy spring 16.So may insure that steel ball The little steel ball 19 of keeper 17, during contacting with reducing chamber 21 internal chamber wall, reduces steel ball as far as possible The lateral wall of keeper 17 and and reducing chamber 21 internal chamber wall between friction, improve the service life of product, Also prevent because long term wear causes product stuck, cause the hidden danger that pipe fitting cannot be extracted.

Above-described embodiment is only preferred embodiment of the present utility model, limits guarantor of the present utility model the most according to this Protect scope, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should contain Within protection domain of the present utility model.
