The hydraulic pressure fast-discharge valve of the monorail crane brake cylinder of the present embodiment, its when in use operation principle and process summary
It is as follows：
In use, the oil inlet P 1 of the hydraulic pressure fast-discharge valve of the monorail crane brake cylinder of the present embodiment is passed through into oil pipe and list
The fuel tank that rail is hung is connected；Working hole P2 is connected with the brake cylinder of monorail crane, and fast row mouth T passes through oil pipe and the oil of monorail crane
Case is connected.
When the brake cylinder of monorail crane needs oil-feed, hydraulic oil injects from the oil inlet P 1 of upper valve base 1, through first flow C,
The brake cylinder of monorail crane is injected after 2 throttle orifice K, the second flow channel D of upper valve base 1 of one-way throttle valve 3 from working hole P2, together
When, hydraulic oil is released from the second flow channel D of the upper valve base 1 first flow F and second flow channel B and hydraulic oil for filling lower valve base 2
Gap 45, and oiling gap 46 is filled by the through hole of the middle and lower part of valve pocket 41, and hydraulic oil is from the third flow channel E of upper valve base 1
Fill the working chamber of grafting valve 4；Now, the valve element 43 of grafting valve 4 bears hydraulic coupling downward in working chamber and spring is downward
Pretightning force, and bear hydraulic coupling upward at oiling gap 46 simultaneously；Because what valve element 43 was subject to makes a concerted effort downwards more than upward
Hydraulic coupling so that the round platform portion of the bottom of valve element 43 is closely plugged together with valve pocket 41, and oil duct between valve element 43 and valve pocket 41 is closed,
The fast row mouthful T of lower valve base 2 is without hydraulic oil pass-out；The hydraulic oil now injected from oil inlet P 1 can only inject single by working hole P2
The brake cylinder that rail is hung.
When the brake cylinder of monorail crane needs quick draining to carry out brake hard, the pressure in the brake cylinder of monorail crane
If oil wants the working hole P2 through upper valve base 1, second flow channel D, 2 throttle orifice K of one-way throttle valve 3, the first flow of upper valve base 1
C and oil inlet P 1 flow back to the fuel tank of monorail crane, due to 2 throttle orifice K of one-way throttle valve 3 reverse throttling action so that
Downward hydraulic coupling is almost unchanged in the working chamber of the valve element 43 of grafting valve 4；And cause second flow channel D, the lower valve base of upper valve base 1
The oil pressure that 2 first flow F and second flow channel B and hydraulic oil releases in gap 45 and oiling gap 46 is raised rapidly, when
The oil pressure in oiling gap 46 is increased to more than when making a concerted effort downwards, the valve element 43 of grafting valve 4 is moved upwards, is inserted suffered by valve element 43
The round platform portion for connecing the bottom of valve element 43 of valve 4 is disengaged with valve pocket 41, and the lower port of valve pocket 41 is opened wide；The brake cylinder of monorail crane
Working hole P2 of the interior pressure oil through upper valve base 1, second flow channel D, the first flow F and second flow channel B and hydraulic pressure of lower valve base 2
Oil is released the pressure that the fast row mouthful T in gap 45, the draining through hole of the valve pocket 41 of grafting valve 4 and lower port and lower valve base 2 is constituted
Oily quick leakage path, the fuel tank through oil pipe quick backflow to monorail crane, so as to realize the brake cylinder brake hard of monorail crane
When the quick of pressure oil release, ensure that monorail crane in emergency situations being capable of quickly brake hard.
Above example is the explanation to embodiment of the present utility model, rather than to limitation of the present utility model,
Person skilled in the relevant technique can also make various changes in the case where not departing from spirit and scope of the present utility model
Change and change and obtain corresponding equivalent technical scheme, therefore all equivalent technical schemes should be included into this practicality newly
The scope of patent protection of type.
