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.
Referring to Fig.1-3, the side of a kind of check-valves, including valve body 1 and spool 3, valve body 1 is water inlet, and valve body 1 is another
Side is water outlet, and spool 3 is located at the inside of valve body 1, and spool 3 is made of conical section 12 and horizontally disposed cylindrical section 15,
And the conical section 12 of spool 3 is located at valve body 1 close to water outlet side, and the annular groove offered on the conical section 12 of spool 3,
And O-ring 13 is equipped in annular groove, first baffle 4 is installed on cylindrical section 15, and cylindrical section 15 far from conical section 12 one
End offers pin hole, and the inside of valve body 1 is the first taper hole section, first level straight hole section, the second taper hole section and second
Horizontal straight hole section composition, second baffle 5 is welded on the inner wall of first level straight hole section, and the inside of valve body 1 is equipped with three
Gusset 6, and first through hole 7 and centre bore 14 are offered on set square 6, and the cylindrical section 15 of spool 3 is far from the one of conical section 12
End is cased with spring 8, plain cushion 9 and nut 10, spring 8, plain cushion 9 and nut 10 across centre bore 14, and on the cylindrical section 15 of spool 3
Positioned at set square 6 close to the side of water inlet, and plain cushion 9 is between spring 8 and nut 10, and nut 10 and 3 screw thread of spool
Connection, and pin hole is internally provided with bolt 11.
The outside of valve body 1 is equipped with outer-hexagonal disk hand 2, and external screw thread 16 is offered on the outer wall of valve body 1, and external screw thread 16
In the both sides of outer-hexagonal disk hand 2, outer-hexagonal disk hand 2 is an integral structure with valve body 1, and the second through-hole, and are offered on plain cushion 9
The quantity three of two through-holes and first through hole 7, and the second through-hole and first through hole 7 are arcuate structure, the conical section 12 of spool 3
It is an integral structure with cylindrical section 15, the section of set square 6 is isosceles triangular structure.
Operation principle：Flow enters the inside of valve body 1 by the water inlet of valve body 1 first, and flow enters inside valve body 1
Afterwards, pass through the second through-hole and first through hole 7 so that under the action of water flow pressure, spool 3 extends to outside the water outlet of valve body 1
Portion, while spring 8 is in compressed state, nut 10 is capable of the elasticity of adjustment spring 8, while bolt 11 avoids nut from occurring
Stripped thread so that nut 10, which loosens, causes valve invalidation, when O-ring 13 enables to spool 3 to be located at the inside of valve body 1, ensures valve
