After screw 150, locking nut 160 is turned, pressure regulating screw 150 can be locked by so that locking nut 160 is close to 100 outer wall of spring base.
When machine oil pump work, it is applied to if the pressure that the machine oil in oil outlet 230 is applied on steel ball 120 is greater than compressed spring 110
When pressure on steel ball 120, steel ball 120 pushed away from steel ball seat 130, and machine oil can be by between steel ball 120 and steel ball seat 130
Gap enters in pressure releasing chamber 250；The suction of lubricating oil pump is further flowed into from oil leak hole 240 into the machine oil in pressure releasing chamber 250
Pressure release movement can be completed in oil duct 210.If the machine oil in oil outlet 230 is applied to the pressure on steel ball 120 less than compressed spring
110 when being applied to the pressure on steel ball 120, and steel ball 120 is fitted closely in the flaring of steel ball seat 130, and machine oil is prevented to enter pressure release
In room 250.
In order to avoid the gap into the machine oil in pressure releasing chamber 250 between pressure regulating screw 150 and the screw hole of spring base 100
Leakage is arranged made of seal rubber between an end face and locking nut 160 of the spring base 100 close to locking nut 160
Gasket.When locking nut 160 to spring base 100 close to when, locking nut 160 gradually squeezes gasket and makes gasket to tune
Screw 150 is pressed to extend, to achieve the effect that sealing.
The beneficial effects of the utility model are: the steel ball seat 130 and pressure releasing chamber of the lubricating oil pump pressure relief device of the utility model
It cooperates in 250 and is provided with screw thread, steel ball seat 130 is threadedly connected to inside pressure releasing chamber 250, can after steel ball seat 130 is worn
