Description
Technical field
The utility model is related to a kind of check valves with sound deadening, belong to check valve technical field.
Background technology
Check valve be fluid can only bead flowing, the device that can not but flow back of outlet medium, fluid is from one end to the other side
Flowing when flowing through valve seat, promotes spool, and the tapered portion of spool is completely enclosed, and the valve body of spool and valve seat with valve seat
Between then leave passage, for fluid by, when fluid by after, spool the pressure of elastic component or fluid effect under playback, weight
New clogging access.Due to there is fluctuation by the Fluid pressure of check valve, inner elements of check valve is due to producing and installing verticality
Influence, it is impossible to accomplish complete dynamic balancing.Under the impact of air-flow, the spool of check valve often vibrates, and collides valve
The inner wall of seat, so as to generate abnormal sound.In addition, when fluid flow direction changes, and spool playbacks under elastic component or pressure effect,
The tapered portion of spool can also generate larger impact to valve seat, cause noise.
Utility model content

In valve chamber, and it can be moved back and forth along valve chamber；The front end of nonreturn valve core is equipped with the conical seal (contact) face with valve seat cooperation, unidirectionally
The side and rear end of spool are equipped with interconnected opening, and the rear end of nonreturn valve core is connected with valve seat by compression spring；The valve chamber
Madial wall be embedded with outer permanent magnetism gib block, the madial wall of the nonreturn valve core is embedded with interior permanent magnetism gib block, and outer permanent magnetism is oriented to
The axial direction of the length direction and nonreturn valve core of item and interior permanent magnetism gib block is consistent；Outer permanent magnetism gib block and interior permanent magnetism gib block be into
To setting, and outer permanent magnetism gib block and interior permanent magnetism gib block are incorgruous setting；The valve seat and nonreturn valve core are copper.
Further, the outer permanent magnetism gib block and interior permanent magnetism gib block have 1 ~ 3 group；Outer permanent magnetism gib block and interior permanent magnetism are led
When being more than 1 to the group number of item, outer permanent magnetism gib block and interior permanent magnetism gib block are respectively positioned on the same side in nonreturn valve core axle center.
Further, the forepart of the nonreturn valve core is equipped with elastic baffle, and elastic baffle is equipped with through hole, the side of elastic baffle
Portion is fixed on the side wall of valve chamber, and elastic baffle is arranged on the front position of nonreturn valve core stroke vertically.
Further, the front end of the valve chamber is equipped with anechoic chamber, and the edge of the elastic baffle is arranged in anechoic chamber, and bullet
Property baffle and the gap location of anechoic chamber are filled up completely by quieter material.
Further, the quieter material is polyester acoustical cotton.
Further, the valve seat includes main body and protecgulum, and protecgulum is to be threadedly coupled with main body, before the anechoic chamber is arranged on
Junction between lid and main body.
Check valve in this programme is equipped with permanent magnetism gib block in the contact position of valve chamber and nonreturn valve core, is led using incorgruous permanent magnetism
The magnetic attraction generated between item makes nonreturn valve core and valve chamber mutually be attracted, can prevent because fluid fluctuate when, nonreturn valve core
It vibrates and is collided with valve chamber inner wall and generate noise；In improvement project, elastic baffle is set in the axial stroke front end of nonreturn valve core,
Effective cushioning effect can be played when nonreturn valve core playbacks, prevents nonreturn valve core from directly impacting generation noise to valve seat；In addition
Anechoic chamber is set in valve chamber front end, further can play the role of sound-absorbing de-noising using anechoic chamber.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of elastic baffle in the utility model.
