Structure is as follows：
Pressure limiting valve 2 includes valve seat 20, ball valve core 234 and the piston component 23 for driving ball valve core to rotate.Valve seat
20 i.e. valve casing, the interior first disengaging aquaporin 201, second that is provided with of valve casing pass in and out aquaporin 202 and bypass channel 200, the first disengaging
The valve seat that aquaporin 201 and second is passed in and out between aquaporin 202 is provided with ball valve core installation cavity 22.Second disengaging aquaporin
It is exactly the above-mentioned output end of pressure limiting valve 2 corresponding to 202, it stretches into inlet and outlet 11 and is tightly connected.The above-mentioned output end of bypass channel 200
Valve seat 20 in be provided with piston component installation cavity 21, the connection ball valve core of piston component installation cavity 21 installation cavity 22.Above-mentioned ball valve
Valve element 234 is located in ball valve core installation cavity 22, and the input of ball valve core 234 connection piston component 23, ball valve core 234 exports
Between the first disengaging aquaporin 201 and second passes in and out aquaporin 202, bypass pressure controls piston component 23 at end, so as to
Control the rotary opening and closing of ball valve core 234.
More specifically, above-mentioned piston component 23 includes permanent magnetic piston 230, the valve for driving ball valve core to rotate
Bar 231 and permanent magnetism pressure ring 232.Permanent magnetic piston 230 includes pressure input face and output face, and the hydraulic pressure of bypass channel output corresponds to
Pressure input face, output face is towards valve element.The one end of valve rod 231 is fixedly connected with ball valve core 234, the other end of valve rod 231 and permanent magnetism
The rotatable engagement of piston 230, permanent magnetic piston 230 are axially pushed close to valve element, will driving stem 231 rotate, so as to movable valve plug
Rotation, permanent magnetism pressure ring 232 are enclosed on outside valve rod 231.Permanent magnetic piston 230 is seal-installed in piston component installation cavity 21 and pressure is defeated
Enter facing to the output end 2001 of bypass channel 200.In order that after obtaining pressure limiting valve closing, external pressure is small to get off and can automatically open up,
Permanent magnetic piston 230 and the position correspondence of permanent magnetism pressure ring 232 and magnetic level is repelled each other, by permanent magnet expulsive force by the pushed home of permanent magnetic piston 230.
Above-mentioned permanent magnetic piston 230 is made up of permanent magnet 2300, non magnetic stud 2302 and sealing ring 2301.Non magnetic stud
2302 are fixed on the middle part of output face.Sealing ring 2301 is enclosed in the outer peripheral sidewall of permanent magnet 2300.Set on non magnetic stud 2302
There is external spiral line, the other end of valve rod 231 is provided with the inner bolt hole with the non magnetic rotation matching of stud 2302.
Above-mentioned bypass channel 200 is L-shaped passage, and the output end of bypass channel 200 corresponds to the center of permanent magnetic piston 230.L-shaped
The side of passage is fixed on outside a lid, and the lid is used to seal at the top of the top of piston component installation cavity 21.Therefore, it is above-mentioned
The output end 2001 of bypass channel 20 be exactly through hole in the middle part of lid, it is connected between L-shaped passage and piston component installation cavity 21.
Lid passes through the open top of 25 fixing seal piston component installation cavity of trip bolt 21.Because bypass channel 200 is L-shaped passage,
Trip bolt 25 can be three pieces not on the same line, good fixing effect.
A circle is provided with the piston component installation cavity 21 of above-mentioned one end of valve rod 231 and the junction of valve core 234 of receiving to seal
Filler 233, permanent magnetism pressure ring 232 is positioned at the top of a circle airtight and watertight padding 233, under the effect of permanent magnetic piston 230, permanent magnetism pressure ring 232
Push and compress airtight and watertight padding 233, so that airtight and watertight padding 233 is sealed on the inwall of piston component installation cavity 21.Utilize elasticity
Compression passes through the elastic means of press seals filler 233 of permanent magnetism pressure ring 232, so as to which and can seals while realizing valve rod rotation, due to not being
Dead sealing, this elastic packing effect are very good.Under normality, permanent magnetism pressure ring 232 just has certain pressure, can elastic means of press seals
Filler 233 keeps sealing.When permanent magnetic piston 230 pushes, because of the repulsion increasing by compression of permanent magnetism spacing so that sealing is more
It is good.
In the foregoing description, specific piston component installation cavity 21 is the chamber of cylinder, and the outer rim of permanent magnetic piston 230 is also in circle
Shape, the outer wall of permanent magnetic piston 230 are sealingly mounted in piston component installation cavity 21 by sealing ring.Permanent magnetic piston 230 and annular are pressed
Piston component installation cavity 21 between circle 232 forms a closed cavity.Pressure limiting valve 2 is provided with display column 24, and display column 24 wraps
Include the fixed and outer wall of valve seat 20 and stretch out in the transparent post 240 of the valve seat outer wall and the floating plug 241 in transparent post.Thoroughly
The bright inner sealing of post 240 connects above-mentioned cavity, and floating plug 241 is seal-installed in transparent post 240.The effect of display column 24 is
Permanent magnetic piston 230 pushes, and driving stem 231 rotates when make it that ball valve core 234 is opened, the floating plug 241 in display column 24 due to
Air pressure makes it be floated in transparent post 240, you can differentiate whether ball valve core 234 is opened, while can also be 241 according to floating plug
Put the substantially aperture for judging ball valve core 234.
In use, when pressure pot external world hydraulic pressure arrives certain value greatly, the output pressure of bypass channel 200 is lived also greater than permanent magnetism
Repulsion between plug 230 and annular pressing ring 232.Now, permanent magnetic piston 230 is pushed, driving stem 231 rotates, and closes ball valve
Core, extraneous current just can not again inject pressure pot, so as to reach the purpose of pressure limiting.
Described above is preferred embodiment of the present utility model, is not departed from for the person of ordinary skill of the art
On the premise of the utility model principle, some variations and modifications can also be made, these also should be regarded as protection of the present utility model
