The axis pin is between the limited block and the mounting table, and the axis pin is blocked by the limited block, the flap with
The internal orifice is adapted, and the sealing hole is located at the top of the limited block.
Preferably, the valve body is equipped with valve deck compatible with the sealing hole；Valve deck is screwed into sealing hole, works as the two
When full contact, valve deck lower end makes to form a sealing space around axis pin into contact with limited block, and axis pin will during the work time
Being locked will not beat, and flap can also be rotated by pin hole around axis pin.
Preferably, the valve deck and the junction of the sealing hole are equipped with washer；After valve deck and sealing hole cooperation, play
Sealing function, the fluid in valve body, which does not leak out, to be come.
Preferably, the inside of the sealing hole is equipped with screw thread, and screw thread is equipped on the outside of the valve deck；Valve deck is logical with sealing hole
Cross threaded connection.
Preferably, the slewing area of the flap is 0 ° to 90 °；0 ° of angle when to refer to flap completely attach to internal orifice,
90 ° refer to flap with internal orifice when perpendicular state, due to the impact of fluid in valve body, flap can by pin hole around axis pin from
By rotating.
Preferably, the length of the axis pin is less than the diameter of the sealing hole；Axis pin and flap are can be taken off, convenient for daily
Maintenance and repair.
Preferably, the internal orifice is equipped with an annular groove, and the flap is equipped with circle compatible with the annular groove
Shape convex block；When fluid is backflowed by outlet pipe in inlet valve body, due to the percussion of fluid, round shape convex block on flap will with it is interior
Annular groove on mouth is adapted, and plays good sealing effect, the case where so as to avoid backflowing, due to using this knot
The leakproofness of structure, valve body will be greatly improved.
The utility model has the beneficial effects that：This valve mechanism is simple, sealing effect is good, can play good non-return work(
Can, simultaneously as axis pin is located in valve body, daily maintenance is carried out convenient for taking out entire flap and axis pin.

Specific embodiment
The principles of the present invention and feature are described below, example is served only for explaining the utility model, and
It is non-to be used to limit the scope of the utility model.
As shown in Figures 1 to 3, in valve body 1, the upper end of the internal orifice 111 of water inlet pipe 11 is equipped with mounting table 4, is set on mounting table 4
There is limited block 41, axis pin 5 is placed between limited block 41 and mounting table 4, flap 2 is connect by connector 21 with pin hole 22, is sold
Hole 22 is adapted with axis pin 5, and axis pin 5 is limited block 41 and blocks, and flap 2, connector 21, pin hole 22 are structure as a whole, and axis pin 5 is inserted
Enter and complete assembly in pin hole 22, then axis pin 5 is placed on mounting table 4, flap 2 can be bonded with internal orifice 111, flap 2 and axis pin 5
After assembling, flap 2 can be rotated by pin hole 22 around axis pin 5, and the angle of rotation is between 0 ° to 90 °.It is also set on valve body 1
There are sealing hole 3, sealing hole 3 to be located at the top of limited block 41, sealing hole 3 is connected through a screw thread with valve deck 13, is equipped in junction
Washer 131 ensures the leakproofness of valve body 1, and after valve deck 13 is fully screwed into sealing hole 3,13 lower end of valve deck can connect with limited block 41
It touches, axis pin 5 is made not beat during the work time, the height of limited block 41 is more than the diameter of axis pin 5, so 13 precession of valve deck is close
After sealing of hole 3, flap 2 can be rotated by pin hole 22 around axis pin 5.The diameter of sealing hole 3 is more than the length and flap 2 of axis pin 5
Diameter is convenient for daily inspection and maintenance, is replaced in time to ensure the sealing of valve body 1 so axis pin 5 and flap 2 can be taken out
Property and non-return effect.
As shown in Fig. 4 to 5, flap 2 is adapted with internal orifice 111, an annular groove 1111 is equipped on internal orifice 111, in valve
Valve 2 is equipped with round shape boss 23, and during fluid backflows, flap 2 is by impact to round shape boss 23 and annular groove
1111 are tightly bonded, and play the role of good non-return.
