Specific embodiment
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, in the description of the present invention, it should be understood that term " on ", "lower", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "top", "bottom", "inner", "outside" is orientation based on the figure or position
Relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning must
There must be specific orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention, show
So, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.It is practical new based on this
Embodiment in type, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, fall within the protection scope of the utility model.
As shown in Figure 1-Figure 3, a kind of check-valves slowing down impact, including water receiving nozzle 1, connector 2, check valve apparatus 3,
Water receiving nozzle 1 is connected by connector 2 with check valve apparatus 3, which is characterized in that check valve apparatus 3 includes pipeline body 4, valve
Core 5, embedded groove 6, permanent magnet 7, sealant 8, guide post 9, spring 10, second level magnet 11, deflector hole 12, spool 5 is close to second level
One end of magnet 11 is equipped with several permanent magnets 7, and second level magnet 11 and permanent magnet 7 are state of repelling each other, inside guide post 9
Equipped with cavity, and spring 10 is located at cavity inside, and the insertion of guide post 9 is installed in embedded groove 6, embedded groove 6 and 10 phase of spring
Connection, embedded groove 6 is located inside spool 5, and embedded groove 6 is integrated with spool 5.
When water flow flows through check valve apparatus 3, water flow will push the movement of spool 5, so that it is crowded to drive embedded groove 6 to move down
Pressing spring 10 slows down impact by the elastic potential energy of spring 10 to provide for spool 5, simultaneously because second level magnet 11 and permanent magnet
7 be state of repelling each other, and when spool 5 is mobile, second level magnet 11 can be close to each other to mutually exclusive with permanent magnet 7, and repulsion
Can increase with the close of second level magnet 11 and permanent magnet 7, further be that spool 5 provides and slows down impact, it is possible to reduce valve
The abrasion of core 5 improves the service life of check-valves.
As shown in Fig. 2-Fig. 3, the contact surface of pipeline body 4 and spool 5 is arc structure, and spool 5 is the circular cone of top arc
Structure, second level magnet 11 are equipped with several deflector holes 12, and second level magnet 11 and pipeline body 4 close to one end of pipeline body 4
It is connected, when 5 bottom of spool is close to second level magnet 11, the partial through holes area of deflector hole 12 can be sheltered from.
When water flow reflux, since 5 bottom of spool can shelter from the partial through holes area of deflector hole 12, so that water flow can push away
Movable valve plug 5 is mobile to 1 direction of water receiving nozzle, and spool 5 is the conical structure of top arc, when spool 5 is mobile, can subtract
The resistance of few water flow and spool 5 further speeds up 5 closing velocity of spool, and using between second level magnet 11 and permanent magnet 7
Repulsion accelerates 5 closing velocity of spool, so as to reduce spool 5 close required water flow strength, can fast implement check-valves pass
It closes.
As shown in Fig. 2-Fig. 3, sealant 8 is located at the junction of guide post 9 and spool 5, and sealant 8 and guide post 9
Outside fit closely, sealant 8 be NBR nitrile rubber made of.
When spool 5 is mobile, the leakproofness of the junction of guide post 9 and spool 5 can be enhanced by sealant 8, avoid
Water flow, which flows into spool 5, causes spring 10 to get rusty, and improves 5 service life of spool.
