Detailed description of the invention
See Fig. 1 ~ Fig. 5, the hydraulic pressure bypass of a kind of band adjustable ball build bidirection press relief valve that the present invention relates to, it
It is connected in parallel on hydraulic pressure main road, it is characterised in that the hydraulic pressure bypass of band adjustable ball build bidirection press relief valve includes that hydraulic pressure bypasses
Left section, hydraulic pressure bypasses right section and is connected to adjustable ball build bidirection press relief valve between the two；Hydraulic pressure bypasses left section
And hydraulic pressure bypasses right section and threadeds with the employing of adjustable ball build bidirection press relief valve.
Described adjustable ball build bidirection press relief valve, it includes housing 801, is provided with inverted T in described housing 1
The cavity of type structure, fluid passage 802 that this cavity includes lateral arrangement and the regulation passage 803 being vertically arranged, described stream
The two ends, left and right of body passage 802 are provided with connection screw thread, are disposed with dust cap from top to bottom in described regulation passage 803
804, slide block 805, spring 806, ball support block 807 and spheroid 808 are sealed, wherein dust cap 804 and regulation passage 803
Top open part is threaded, has a regulation screw mandrel 809 pass dust cap 804 from the top down and be connected to seal slide block 805
Top, regulation screw mandrel 809 threaded with dust cap 804, on the regulation screw mandrel 809 above dust cap 804 also revolve be equipped with lock
Jack panel 8011, the outward flange of described sealing slide block 805 fits with the inwall of regulation passage 803, is sealing outside slide block 805
Being provided with sealing ring 8010 between the inwall of edge and regulation passage 803, the two ends up and down of described spring 806 connect sealing respectively
The bottom of slide block 805 and the top of ball support block 807, described spheroid 808 is fixedly installed in ball support block 807 times
Portion, the lower semisection longitudinal cross-section of described spheroid 808 coincide with the cross section of fluid passage 802, under naturalness, due to spring 806
Elastic force so that when spheroid 808 is close to the bottom of fluid passage 802, fluid laterally can not lead in fluid passage 802
Cross.
A kind of method of work of adjustable ball build bidirection press relief valve:
First according to the setting pressure of fluid, regulation screw mandrel is adjusted, thus the elastic potential energy of spring is adjusted,
Final control fluid pressure release value in fluid passage；
When hydraulic pressure main road is unobstructed, the pressure at the two ends, left and right of adjustable ball build bidirection press relief valve is equal, and spheroid is in
Low level, spheroid is failure to actuate；
Embodiment 1, when liquid flows from left to right and hydraulic pressure main road is obstructed, adjustable ball build bidirection press relief valve
Left end pressure is more than right-hand member pressure, owing to the pressure in the fluid passage on the left of spheroid is more than in the fluid passage on the right side of spheroid
Pressure, fluid forces spheroid moves up, bottom spheroid formed for fluid motion space, fluid in fluid passage from left-hand
Right motion, thus reach the purpose of pressure release, until the pressure on the left of spheroid and right side is equal, spheroid is put in order in situ, hydraulic pressure main road
Return unobstructed.
Embodiment 2, when liquid flows from left to right and hydraulic pressure main road is obstructed, adjustable ball build bidirection press pressure release
The right-hand member pressure of valve is more than left end pressure, owing to the pressure in the fluid passage on the right side of spheroid is more than the fluid passage on the left of spheroid
In pressure, fluid forces spheroid moves up, bottom spheroid formed for fluid motion space, fluid in fluid passage from
Dextrad left movement, thus reach the purpose of pressure release, until the pressure on the left of spheroid and right side is equal, spheroid is put in order in situ, hydraulic pressure
Main road returns unobstructed.
