Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figure 1, the non-return valve includes valve body 10, the movable part 20 that is movably arranged in the valve body 10 and lid Lid 30 set on 10 top of valve body.

The valve body 10 is inverted T-shape comprising an incoming line 11 with the incoming line 11 connect and is oppositely arranged One outgoing line 12, the intermediate duct 13 being connected between the incoming line 11 and outgoing line 12 and with the intermediate duct The valve pipeline 15 that 13 middle parts connect.The introduction channel 110 of a straight extension is equipped in the incoming line 11, in the outgoing line 12 Export channel 120 equipped with a straight extension.It is connect with introduction channel 110 equipped with one in the intermediate duct 13 and inside obliquely The lower tilting section 130, one extended connect with export channel 120 and extends internally obliquely and be located at 130 top of lower tilting section Upper tilting section 131 and it is connected to the connection extended between the inner end of the lower tilting section 130 and the inner end of upper tilting section 131 and vertically Section 132.The internal diameter of the lower tilting section 130 is less than the internal diameter of introduction channel 11, and internal diameter of tilting section 131 is less than export channel on this 120 internal diameter.The internal diameter of the internal diameter of the lower tilting section 130, the internal diameter of upper tilting section 131 and linkage section 132 is identical.The lower inclination Section 130 is arranged in parallel with upper tilting section 131.

The valve pipeline 15 upwardly extends setting by intermediate duct 13, and movable part channel 150 is equipped in the valve pipeline 15.It is described Movable part 20 can up and downly be contained in movable part channel 150, and when movable part 20 is not by outer force effect, gear is set to upper The internal orifice end of tilting section 131.The lid 30 is detachably secured on valve pipeline 15.20 top of movable part is equipped with one to downward The threaded hole 151 stretched.The movable part 20 can be metallic object or plastic body, the metallic object can be body of stainless steel, copper body or cast-iron body, The plastic body can be polyethylene body or polypropylene body.Please refer to Fig. 2, which further includes can be with the screw thread of movable part 20 The removal piece 50 that hole 151 coordinates, the removal piece 50 include that can extend to the screw rod 51 coordinated in threaded hole 151 and with it and positioned at valve The handle 52 ontology 10 outside and be connected with 51 end of screw rod.

In use, the introduction channel 110 by incoming line 11 introduces fluid, via the lower tilting section of intermediate duct 13 It is flowed up along linkage section 132 after 130, to which movable part 20 is moved up exposing above tilting section 131 along movable part channel 150 Internal orifice end, make fluid flowed through again along upper tilting section 131 have export channel 120 flow out, pass through in 110 no fluid of introduction channel When, movable part 20 gear set on upper tilting section 131 internal orifice end, thus prevent air-flow back through.Due to 20 top of movable part Equipped with threaded hole 151, when having impurity accumulation in intermediate duct 13, lid 30 can be disassembled, be realized by removal piece 50 The taking-up of movable part, the non-return valve is simple in structure, and production efficiency is high.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection domain within.
