Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder.
Background technique
The major components of hydraulic transmission are dynamicliquid pressure oil cylinders, it can establish sufficiently large operational forces, actuator
It is easily achieved process control movement, work safety, and most can sufficiently be met in terms of use condition, limitation quality and contour dimension
Modern comfort proposed requirement.
Existing ship hydraulic cylinder, due to the effect of the not throttling of governor valve in falling process of heavy, weight is under
It is unstable during falling, to affect the security performance used.
Utility model content
In order to solve the above problem existing for existing hydraulic cylinder peculiar to vessel, the present invention provides a kind of with individual event speed governing valve
Ship hydraulic cylinder.
The utility model technical solution used for the above purpose is: the ship hydraulic with individual event speed governing valve
Cylinder, cylinder body rear portion are connect with cylinder tail, and piston rod is equipped in cylinder body, and cylinder body leading inside connects guide sleeve, and piston rod is through installation
In in guide sleeve, piston rod rear end installs piston, and piston rod front end connects preceding earrings, pacifies from the bottom to top in the hydraulic fluid port on cylinder tail top
Dress throttle valve, gasket and locking nut, locking nut are fixedly installed in hydraulic fluid port, and oil is equipped in the middle part of locking nut and gasket
Hole is uniformly distributed hole on throttle valve.
The piston rod and guide sleeve clearance fit are installed, and piston rod and guide sleeve pass through cylinder piston rod seal ring assembly
Sealing.
The ship hydraulic cylinder with individual event speed governing valve of the utility model is made up of throttle valve, gasket, locking nut
Individual event governor valve play the role of throttling, make weight more steady in dropping process, safety.

Specific embodiment
The ship hydraulic cylinder structure with individual event speed governing valve of the utility model is as shown in Figure 1, the sliding of piston rod 2 is contained in
In cylinder body 1, cylinder body 1 is integrated after welding with cylinder tail 5, and preceding earrings 6 is threadedly coupled with piston rod 2, and guide sleeve 4 is threadedly connected to cylinder
It on body 1, cylinder piston rod 2 and 4 clearance fit of guide sleeve and is sealed by cylinder piston rod seal ring assembly, by throttle valve 7, close
The individual event speed limit valve arrangement that packing 8, locking nut 9 form is installed in the hydraulic fluid port of cylinder tail 5, and locking nut 9 is fixedly installed in oil
In mouthful, it is equipped with oilhole in the middle part of locking nut 9 and gasket 8, is uniformly distributed hole 10 on throttle valve 7.
Hydraulic cylinder works principle: being divided for rod chamber and rodless cavity by piston 3 in hydraulic cylinder, which is consolidated by cylinder tail 5
Due in equipment, when hydraulic cylinder rodless cavity oil inlet, piston rod 2 and preceding earrings 6 are ejected, and preceding earrings 6 is connect to will with weight
Weight lifts, which does not need current limliting, normal operation, when piston rod 2 and the retraction of preceding earrings 6, due to weight
The self weight of object, it is steady in order to fall weight after rise, it is risen at this time by the individual event governor valve that throttle valve 7, gasket 8, locking nut 9 form
To the effect of throttling, make weight more steady in dropping process, safety.
The working principle of governor valve: when hydraulic fluid port (i.e. rodless cavity) oil inlet of governor valve is installed, i.e., when piston rod 2 stretches out, section
Stream plug 7 sinks to hydraulic fluid port least significant end and sealing ring 8 under the action of oil pressure and separates, and hydraulic oil normally enters, and does not influence flow velocity, works as work
When stopper rod 2 bounces back, install governor valve hydraulic fluid port (i.e. rodless cavity) it is fuel-displaced when, orifice plug 7 is tight with sealing ring 8 under the action of oil pressure
It sticks together, the circular hole around orifice plug 7 is shut by sealing ring, to play the role of throttling.
The utility model is described by embodiment, and those skilled in the art know, practical new not departing from this
In the case where the spirit and scope of type, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, at this
Under the introduction of utility model, it can modify to these features and embodiment to adapt to particular situation and material without taking off
Spirit and scope from the utility model.Therefore, the utility model is not limited to the particular embodiment disclosed, and is owned
The embodiment fallen within the scope of claims hereof belongs to the protection scope of the utility model.
