Abstract
The utility model relates to a power unit structure which comprises a valve plate, an overflow valve, a one-way valve, a throttle valve and a manual unloading valve. The overflow valve is fixed on the valve plate in screw thread and instrumentation mode. The one-way valve is fixed on the valve plate in screw thread and instrumentation mode and forms a right angle with the instrumentation direction of the overflow valve. The manual unloading valve is fixed on the valve plate in screw thread and instrumentation mode and on the same side with the one-way valve. The throttle valve is fixed on the valve plate in screw thread and instrumentation mode and forms a right angle with the instrumentation direction of the manual unloading valve. The power unit structure has the advantages of being small in structural size, little in noise and convenient to operate.
Description
Technical field
The utility model relates to a kind of power unit structure, relate in particular to a kind of car lift power unit structure.
Background technique
Traditional hydraulic power unit structure is widely used in car lift, hydraulic pressure fork truck, shear-type elevator etc.The hydraulic power unit structural volume that has now is big, and noise is big, inconvenient operation, and system is subject to outside contamination, and the pressurize ability and the down maneuver of system are relatively poor.
The model utility content
The utility model provides the power unit structure that a kind of structural volume is little, noise is low, easy to operate.
In order to overcome the defective that exists in the background technique; The utility model solves the technological scheme that its technical problem adopted: a kind of power unit structure; Comprise valve plate, relief valve, one-way valve, throttle valve, manual unloading valve, described relief valve is fixed on the valve plate with the mode of thread cartridge; Described one-way valve is fixed on the valve plate and with the relief valve cartridge insertion direction with the mode of thread cartridge and meets at right angles; Described manual unloading valve be fixed on the valve plate with the mode of thread cartridge and with one-way valve with on one side; Described throttle valve is fixed on the valve plate with the mode of thread cartridge and meets at right angles with the cartridge insertion direction of manual unloading valve.
Comprise that further the insertion portion of described relief valve is communicated with the insertion portion of one-way valve; The insertion portion of described manual unloading valve is communicated with the throttle valve insertion portion; Described manual unloading valve is communicated with through pipeline with one-way valve.
Comprise that further described valve plate is rectangular steel plate.
Beneficial effect: the utility model has solved the defective that exists in the background technique, has reduced the volume of system, has reduced machine noise, and all valves all adopt the thread cartridge structure, assembly and adjustment separately, and overall cost is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Wherein: 1, valve plate; 2, relief valve; 3, one-way valve; 4, throttle valve; 5, manual unloading valve.
Embodiment
A kind of power unit structure as shown in Figure 1 comprises valve plate 1, relief valve 2, one-way valve (3), throttle valve 4, manual unloading valve 5, relief valve 2 be fixed on the valve plate 1 with the mode of thread cartridge; One-way valve 3 is fixed on the valve plate 1 and with relief valve 2 cartridge insertion directions with the mode of thread cartridge and meets at right angles; Manually unloading valve 5 be fixed on the valve plate 1 with the mode of thread cartridge and with one-way valve 3 with on one side; Throttle valve 4 is fixed on the valve plate 1 with the mode of thread cartridge and meets at right angles with the cartridge insertion direction of manual unloading valve 5; The insertion portion of relief valve 2 is communicated with the insertion portion of one-way valve 4; Manually the insertion portion of unloading valve 5 is communicated with throttle valve 4 insertion portions; Manually unloading valve 5 and one-way valve 3 are communicated with through pipeline; Valve plate 1 is rectangular steel plate.Under the conditional situation of some working condition requirement system bulk, be fit to supporting use, reduced the volume of system, all valves all adopt the thread cartridge structure, assembly and adjustment separately, and overall cost is low.
Should be appreciated that specific embodiment described above only is used to explain the utility model, and be not used in qualification the utility model.By the spirit conspicuous variation of being extended out of the utility model or change and still be among the protection domain of the utility model.
