Specific embodiment
Referring to Fig. 1 ~ Fig. 5, a kind of hydraulic pressure bypass with adjustable ball figure bidirection press relief valve of the present invention, it
It is connected in parallel on Hydraulic Main road, it is characterised in that the hydraulic pressure bypass with adjustable ball figure bidirection press relief valve includes hydraulic pressure bypass
Left section, right section of hydraulic pressure bypass and be connected to adjustable ball figure bidirection press relief valve between the two；Left section of hydraulic pressure bypass
And right section of hydraulic pressure bypass and adjustable ball figure bidirection press relief valve are using being threadedly coupled.
The adjustable ball figure bidirection press relief valve, it includes shell 801, is provided with inverted T in the shell 1
The cavity of type structure, the cavity include the fluid channel 802 of lateral arrangement and the adjusting channel 803 that is vertically arranged, the stream
The left and right ends in body channel 802 are provided with connection screw thread, are disposed with dustproof cover from top to bottom in the adjusting channel 803
804, sliding block 805, spring 806, ball support block 807 and sphere 808 are sealed, wherein dustproof cover 804 and adjusting channel 803
Top open part is threadedly coupled, and is had an adjusting screw rod 809 to pass through dustproof cover 804 from the top down and is connected to sealing sliding block 805
Top, adjust screw rod 809 and be threadedly coupled with dustproof cover 804, also revolved on the adjusting screw rod 809 above dustproof cover 804 and be equipped with lock
The outer edge of tight nut 8011, the sealing sliding block 805 fits with the inner wall for adjusting channel 803, in the outer of sealing sliding block 805
It is provided with sealing ring 8010 between edge and the inner wall for adjusting channel 803, the upper and lower ends of the spring 806 are separately connected sealing
The bottom of sliding block 805 and the top of ball support block 807, the sphere 808 are fixedly installed under ball support block 807
Portion, the lower semisection longitudinal cross-section of the sphere 808 and the section of fluid channel 802 coincide, under natural conditions, due to spring 806
Elastic force so that sphere 808 be close to fluid channel 802 bottom when, fluid cannot be carried out out of fluid channel 802 laterally lead to
It crosses.
A kind of working method of adjustable ball figure bidirection press relief valve:
It is adjusted first according to the setting pressure of fluid to screw rod is adjusted, thus to be adjusted to the elastic potential energy of spring
Section, the final pressure release value for controlling fluid in fluid channel；
When hydraulic main road is unobstructed, the pressure of the left and right ends of adjustable ball figure bidirection press relief valve is equal, sphere
In low level, sphere is failure to actuate；
