Embodiment 1, refering to shown in Fig. 1 and Fig. 2,
Refer to Fig. 1 and Fig. 2, present embodiments provide a kind of check-valves 100, including valve body 110, flap 120 and valve gap
130.Wherein, valve body 110 includes interconnective water inlet pipe 111 and drain pipe 112.
Referring to Fig. 2, water inlet pipe 111 is flap installation end 124 near one end of drain pipe 112, and flap installation end 124 sets
Be equipped with mouth of pipe inclined-plane 113, flap 120 and mouth of pipe inclined-plane 113 be hinged so that flap 120 can with mouth of pipe inclined-plane 113 laminating and
Separate.
It should be noted that flap 120 position hinged with mouth of pipe inclined-plane 113 is not specifically limited, in the present embodiment,
The articulated elements 114 for being connected flap 120 it is provided with in the junction on mouth of pipe inclined-plane 113 with the outer wall of water inlet pipe 111.So set
Putting the advantage being arranged on the outer wall of water inlet pipe 111 relative to articulated elements 114 is: the scope enabling to flap unlatching is bigger,
The blowdown flow rate of same time is bigger.Specifically, water inlet pipe 111 is set to connect end 115 away from one end of flap installation end 124,
Mouth of pipe inclined-plane 113 is gradually distance from connection end 115 by articulated elements 114 along the diameter of water inlet pipe 111.Mouth of pipe inclined-plane 113 and flap
The setting of 120 make use of gravity principle of start-stop, when sewage is entered by water inlet pipe 111, flap 120 under the promotion of medium towards away from
The direction on mouth of pipe inclined-plane 113 swings, and the outlet of water inlet pipe 111 is opened, and medium is flowed to drain pipe 112 by water inlet pipe 111, thus is situated between
Matter can pass through check-valves 100, and when the mobilization force of medium disappears, flap 120 is under the partical gravity effect of self, towards close
The direction on mouth of pipe inclined-plane 113 swings.Such design, it is to avoid use complicated structure, such as spring etc..Spring is easily given birth to
Rust, and it is unfavorable for the discharge of lump, easily cause body blocking.
The angle of inclination on mouth of pipe inclined-plane 124 is not specifically limited, and in the present embodiment, simultaneously takes account of and is easy to flap 120
Opening and closing, set the angle of inclination on mouth of pipe inclined-plane 124 as 50-60 °.It should be noted that angle of inclination here refers to
: the angle of the axial line of mouth of pipe inclined-plane 124 and water inlet pipe 111.
The selection of articulated elements 114 is not particularly limited, and in the present embodiment, articulated elements 114 is the bearing pin of stainless steel,
Bearing pin is fixed on the outer wall of water inlet pipe 111, and flap 120 is set on bearing pin, and can overturn around bearing pin.In the present embodiment, valve
Lobe 120 be sized to cover the outlet of water inlet pipe 111, the most in other embodiments, flap 120 can also
More somewhat larger than the outlet of water inlet pipe 111.The material of flap 120 is not especially limited, in the present embodiment, in order to avoid life
The situations such as rust, flap 120 is stainless steel.
It should be noted that in order to make flap 120 more preferable, at flap 120 and the mouth of pipe with the sealing effectiveness on mouth of pipe inclined-plane 113
Being provided with the second sealing member 116 between inclined-plane 113, the second sealing member 116 is connected with mouth of pipe inclined-plane 113 or flap 120.
Specifically, the connected mode of the second sealing member 116 does not do concrete setting, in the present embodiment, it is provided that following three
Kind can connected mode for reference, but be not limited to following three kinds of connected modes.
The first connected mode is: the second sealing member 116 is sealing ring, and the edge on mouth of pipe inclined-plane 113 arranges multiple
Recess, arranges multiple projection in multiple recess corresponding positions of flap 120 with mouth of pipe inclined-plane 113, and sealing ring is arranged on mouth of pipe inclined-plane
The edge of 113;Edge on mouth of pipe inclined-plane 113 arranges multiple projection, in multiple projections of flap 120 with mouth of pipe inclined-plane 113
Corresponding position arranges multiple recess, and sealing ring is arranged on flap 120 and includes the position of multiple recess towards the one side on mouth of pipe inclined-plane 113
Put.So design, increases the contact area of flap 120 and mouth of pipe inclined-plane 113 interference fit, and sealing effectiveness is more preferable.
The second connected mode is: the second sealing member 116 is diaphragm seal, and diaphragm seal is arranged on whole flap 120 towards pipe
The one side on mouth inclined-plane 113.So being fully contacted of design, beneficially flap 120 and mouth of pipe inclined-plane 113.
The third connected mode is: the second sealing member 116 is sealing ring, and it is oblique towards the mouth of pipe that sealing ring is arranged on flap 120
The one side in face 113 or be arranged on the edge on mouth of pipe inclined-plane 113.
