Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive
Feature and/or step beyond, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary, accompanying drawing), unless chatted especially
State, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, each feature is only
It it is an example in a series of equivalence or similar characteristics.
As shown in Figures 1 to 6, gravity release hydraulicdirectional control valve, this reversal valve by protecgulum 7, bonnet 11, reversing handle 3,
Spool 9 and valve body 10 form, and described valve body 10 is provided with tri-hydraulic fluid ports of P, T, A, and valve body 10 is internal is provided with spool 9, and spool 9 overlaps
Equipped with spring 8, the rearward end of described valve body 10 is provided with bonnet 11, and the leading section of valve body 10 is provided with protecgulum 7, protecgulum 7, bonnet 11 with
Valve body 10 junction is equipped with sealing ring 6；Described protecgulum 7 is provided with a bar 5, and seat bar 5 is fixed with reversing handle 3, described in change
Being connected with spool 9 by connecting rod 4 to handle 3, reversing handle 3 is connected by locking nut 1 pulling force adjusting nut 1；
Cut-off valve rod 12, valve seat 13, locking nut 2 14 and hand rotary nut 15, the top of cut-off valve rod 12 it is integrated with at described hydraulic fluid port A
Suitable with hydraulic fluid port A, the bottom of cut-off valve rod 12 is arranged on valve seat 13, is provided with sealing member 16 between valve seat 13 and valve body 10,
Being provided with locking nut 2 14 below valve seat 13, described hand rotary nut 15 matches with locking nut 2 14 locking.
This valve is two-position three-way hand change valve, and when the present invention uses on lifesaving appliance, wherein, P mouth connects drawworks brake
Device, T mouth takes back fuel tank, and A mouth connects accumulator, and its operation principle is shown in accompanying drawing 5, i.e. reversal valve function figure.
The present invention when reversing handle 3 in position time, P mouth connects under spring force with T mouth, and A mouth is closed, now because of
Brake hydraulic fluid port is connected with fuel tank, and no pressure in brake, so winch will not rotate, can carry out jib accumulation of energy and pour out dynamic
Make.Treating that outboard all poured out by jib, when on ship, operator pull reversing handle 3 by remote control steel wire rope, spool 9 overcomes spring
8 power commutations, make P mouth connect with A mouth, and T mouth is closed.Now, the pressure oil in accumulator enters winch stop assembly by reversal valve
Opening brake, winch starts slowly to decline, and declines after putting in place, and operator unclamp remote control steel wire rope, and reversing handle 3 is at spring 8
Returning under the effect of power in situ, lose pressure oil in brake, winch stops declining.
The pulling force that the invention enables remote control steel wire rope can be regulated by regulation reversing handle 3 upper pulling force within the specific limits
Nut 1 adjusts, and pulling force adjusting nut 1 upwards revolves, and lineoutofservice signal pull reduces, and pulling force regulation increases to backspin, lineoutofservice signal pull,
Regulate complete, screw locking nut 2.
Spring force is the invention enables to be enlarged to 80N, it is ensured that reset reliable and be not easy misoperation, greatly enhancing
Safety.The present invention is also integrated with cut-off valve rod 12, valve seat 13, locking nut 2 14 and hand rotary nut 15 on valve body 10,
When not using gravity release function, valve can cut out by screwing hand rotary nut 15, it is ensured that in operation, though behaviour by mistake
Made remote control steel wire rope, gravity release function also will not action, improve the security reliability of lifesaving appliance.
Particular embodiments described above, has been carried out the purpose of the present invention, technical scheme and beneficial effect the most in detail
Describe in detail bright, be it should be understood that the specific embodiment that the foregoing is only the present invention, be not limited to the present invention.This
Invention expands to any new feature disclosed in this manual or any new combination, and the arbitrary new method that discloses or
