Detailed description of the invention
Seeing Fig. 1 ~ Fig. 5, the hydraulic pressure heat-exchange system of the hydraulic pressure of a kind of band ball-type relief valve that the present invention relates to bypass, it includes equipment heating source 1, radiator 5 and the reserving liquid tank 2 that oil circulation is connected, and the side of described radiator 5 is provided with cooling fan 9.It is arranged in parallel ball-type relief valve 8 on the oil circuit at radiator 5 two ends, on oil circuit or on reserving liquid tank 2, temperature sensor has been set.
nullDescribed ball-type relief valve 8 includes housing 801，The cavity of inverted T-type structure it is provided with in described housing 1，Fluid passage 802 that this cavity includes lateral arrangement and the regulation passage 803 being vertically arranged，The two ends, left and right of described fluid passage 802 are provided with connection screw thread，Dust cap 804 it is disposed with from top to bottom in described regulation passage 803、Seal slide block 805、Spring 806、Ball support block 807 and spheroid 808，Wherein dust cap 804 is threadeded with the top open part of regulation passage 803，There is a regulation screw mandrel 809 from the top down through dust cap 804 top being connected to seal slide block 805，Regulation screw mandrel 809 is threadeded with dust cap 804，On regulation screw mandrel 809 above dust cap 804, also rotation is equipped with locking nut 8011，The outward flange of described sealing slide block 805 fits with the inwall of regulation passage 803，It is provided with sealing ring 8010 between the outward flange of slide block 805 and the inwall of regulation passage 803 sealing，The two ends up and down of described spring 806 connect bottom and the top of ball support block 807 sealing slide block 805 respectively，Described spheroid 808 is fixedly installed in the bottom of ball support block 807，The lower semisection longitudinal cross-section of described spheroid 808 coincide with the cross section of fluid passage 802，Under naturalness，Elastic force due to spring 806，When making the bottom that spheroid 808 is close to fluid passage 802，Fluid can not carry out in fluid passage 802 laterally across.
A kind of method of work of the hydraulic pressure heat-exchange system of the hydraulic pressure bypass of band ball-type relief valve:
