first step hole 101 of check valve body 1;Described fast inserting combined type check valve, successively quick connector body 9 is pressed into the second step hole 102 of check valve body 1, first quick connector body 14 is pressed into the 3rd stepped hole 103 of check valve body 1, second quick connector body 15 is pressed into the 4th stepped hole 104 of check valve body 1, 3rd quick connector body 16 is pressed into the stepped hole the 5th 105 of check valve body 1, 4th quick connector body 17 is pressed into the 6th stepped hole 106 of check valve body 1, 5th quick connector body 18 is pressed into the 7th stepped hole 107 of check valve body 1, 6th quick connector body 19 is pressed into the 8th stepped hole 110 of check valve body 1, 7th quick connector body 20 is pressed in the 9th stepped hole 111 of check valve body 1;Described connector 7 press-fits fixing with quick connector body 9 employing, the cannelure 702 of connector 7 is sequentially loaded into the second sealing ring 8, then pressing fit in the small end face endoporus 902 in quick connector body 9, the annular teeth 701 of connector 7 embeds in first face of cylinder 901 of quick connector body 9;When plastic flexible pipe connects, it is possible to plastic flexible pipe is inserted directly into the first endoporus 903 place in quick connector body 9;Described sealing gasket 4 installs to first step 101 place in check valve body 1, when gas or liquid enter first step hole 101 from the second step hole 102 of check valve body 1 or the 7th stepped hole 107, under pressure and spring effect, sealing gasket compresses the effect playing sealing, gas or liquid is stoped to enter the 3rd stepped hole 103, 4th stepped hole 104, 5th stepped hole 105, 6th stepped hole 106, in 8th stepped hole 110 or the 9th stepped hole 111, in turn when gas or liquid are from the 3rd stepped hole 103, 4th stepped hole 104, 5th stepped hole 105, 6th stepped hole 106, when 8th stepped hole 110 or the arbitrary stepped hole of the 9th stepped hole 111 enter, under pressure, gas or liquid will back down sealing gasket 4 and spring 3 enters in second step hole 102 and the 7th stepped hole 107, thus reaching the purpose of one-way sealing;Quick connector body 9 is respectively provided with plastic tube, the 3rd sealing ring 10, retainer ring 11 in holding greatly, the lower surface of the 3rd sealing ring 10 is withstood in the upper surface of described retainer ring 11, described retainer ring 12 be arranged below snap ring 13 and hold-down ring 12, hold-down ring 12 and snap ring 13 adopt inside and outside taper-face contact to fix;Retainer ring 12 is assemblied in and internal utilizes hold-down ring 12 to fix, the conical surface utilizing both between snap ring 13 and hold-down ring 12 is fixed, and the conical surface 1102 top contacts with snap ring inner conical surface 1302 under retainer ring, adopt between last hold-down ring annular teeth 1204 and the quick connector body face of cylinder 906 and embed encapsulation;Described 3rd sealing ring 10 installs to the second endoporus 904 place in quick connector body 9, and gas or liquid utilize self sealss principle after entering special-shaped groove under pressure, and sealing ring plays the effect of sealing to both sides extruding.Retainer ring 11 installs to the 3rd endoporus 905 place in quick connector body 9, plays the effect of fixed seal ring.Snap ring 13 loads in hold-down ring 12, and then snap ring 13 loads quick connector together with hold-down ring 12, and this is internal, and snap ring 13 locks plastic tube together with hold-down ring 12.First plastic tube is inserted in use in snap ring 13, under thrust, the lower conical surface 1202 with retainer ring is contacted by the inner conical surface of snap ring 13, retainer ring 12 will make snap ring 13 opened with certain angle, plastic tube will be inserted into quick connector body interior step 903 place always, under pretightning force effect, plastic tube is locked by the tapered tooth of snap ring 13 automatically, when plastic tube moves out under external force, snap ring 13 and hold-down ring 12 1 work generation contractility, and plastic tube is tightly locked.When dismantling plastic tube, touch forward snap ring 13 with extracting tool, make the inner conical surface 1302 of snap ring 13 withstand the lower conical surface 1202 of retainer ring 12, allow snap ring 13 opened with certain angle, now plastic tube quickly can be extracted out;This one-way valve structures good airproof performance, to bear pressure big, be connected firmly, safety, antivibration, reliability high, different operating modes under suitable varying environment, and assemble and be simply not limited by a space, efficiency of assembling is high;Embodiment described above, the simply one of the present invention more preferably detailed description of the invention, the usual variations and alternatives that those skilled in the art carries out within the scope of technical solution of the present invention all should be included in protection scope of the present invention.
