Specific implementation mode
It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this
Utility model.
Referring to Fig.1-3, the safety valve of the utility model embodiment, including valve body 1, valve seat 2 and sealing element 3, valve body 1 are fixed
On valve seat 2,1 middle part of valve body is equipped with the chamber 11 of perforation, and 2 middle part of valve seat is equipped with the first fluid channel being connected to chamber 11
21,1 outer wall of valve body is vertically equipped with the second fluid channel 12 being connected to chamber 11 along its axis, and sealing element 3 is movably disposed in
First fluid channel 21 leans on the exit of 11 one end of abluminal compartment, sealing element 3 to be equipped with the first magnet 4, and chamber 11 is far from sealing element 3
One end be equipped with the second magnet 5 for repelling with 4 phase of the first magnet.
The safety valve of the present embodiment makes sealing element 3 hold out against by the repulsion between the first magnet 4 and the second magnet 5
One fluid channel 21 leans on the exit of abluminal compartment 11, when the Fluid pressure in pipeline is less than this repulsion, the fluid in pipeline
Or combustion gas can not be flowed to by first fluid channel 21 in chamber 11, second fluid channel 12 is flowed out without fluid or combustion gas;Work as pipe
When Fluid pressure in road is more than this repulsion, sealing element 3 leaves 21 exit of first fluid channel, the fluid in pipeline or combustion
Gas flows into chamber 11 by first fluid channel 21, is then discharged from second fluid channel 12, and pipeline carries out pressure release, until pipeline
Interior Fluid pressure is less than the repulsion between the first magnet 4 and the second magnet 5, and sealing element 3 is held out against again in first fluid channel
21 lean on the exit of abluminal compartment 11, pipeline to stop pressure release.
The chamber 11 of the present embodiment is equipped with capping 6 far from one end of sealing element 3, and capping 6 is threadedly coupled with valve body 1;In this way
First the element in chamber 11 can be installed when mounted, then lock capping 6, whole installation process is more convenient.In order to make
Safety valve is suitable for the pipeline pressure under a variety of pressure conditions and adjusts, logical equipped with the screw thread being connected to chamber 11 at 6 middle part of capping
Hole 61 is connected with adjusting screw rod 7 on tapped through hole 61, and the second magnet 5 is fixed on adjusting screw rod 7 close to one end of sealing element 3;This
Sample can rotate adjusting screw rod 7 according to actual needs, be adjusted to the distance between the first magnet 4 and the second magnet 5, it
Between repulsion with actual needs be adapted, the use of safety valve is more extensive.Correspondingly, the second magnetic is fixed for the ease of installation
