Description

Ship hydraulic cylinder with individual event speed governing valve
Technical field
The present invention 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.
Summary of the invention
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.
Present invention technical solution used for the above purpose is: the ship hydraulic cylinder with individual event speed governing valve, cylinder Body rear portion is connect with cylinder tail, and piston rod is equipped in cylinder body, and cylinder body leading inside connects guide sleeve, and piston rod, which runs through, is installed on guiding In set, piston rod rear end installs piston, and piston rod front end connects preceding earrings, installation throttling from the bottom to top in the hydraulic fluid port on cylinder tail top Valve, gasket and locking nut, locking nut are fixedly installed in hydraulic fluid port, and oilhole, section are equipped in the middle part of locking nut and gasket Hole is uniformly distributed on stream 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.
Ship hydraulic cylinder with individual event speed governing valve of the invention, the list being made up of throttle valve, gasket, locking nut Item governor valve plays the role of throttling, makes weight more steady in dropping process, safety.
Detailed description of the invention
Fig. 1 is the ship hydraulic cylinder overall structure figure that the present invention has individual event speed governing valve.
Fig. 2 is locking nut structure figure of the present invention.
Fig. 3 is gasket structure figure of the present invention.
Fig. 4 is throttle valve main view sectional structure chart of the present invention.
Fig. 5 is throttle valve overlooking structure figure of the present invention.
In figure: 1, cylinder body, 2, piston rod, 3, piston, 4, guide sleeve, 5, cylinder tail, 6, preceding earrings, 7, throttle valve, 8, sealing Pad, 9, locking nut, 10, hole.
Specific embodiment
Ship hydraulic cylinder structure with individual event speed governing valve of the invention is as shown in Figure 1, the sliding of piston rod 2 is contained in cylinder body In 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 body 1 On, it 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, sealing The individual event speed limit valve arrangement that pad 8, locking nut 9 form is installed in the hydraulic fluid port of cylinder tail 5, and locking nut 9 is fixedly installed in hydraulic fluid port It is interior, 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 present invention is described by embodiment, and those skilled in the art know, is not departing from spirit of the invention In the case where range, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in religion of the invention It leads down, can modify to these features and embodiment to adapt to particular situation and material without departing from essence of the invention Mind and range.Therefore, the present invention is not limited to the particular embodiment disclosed, fallen with claims hereof Embodiment in range belongs to protection scope of the present invention.
