The utility model discloses a realize out that the oil among the oil pipe carries out effectual backward flow to prevent that its stream from to environment in, causing the wasting of resources and environmental pollution's the condition.
Description
Technical field
This utility model is related to a kind of Hydraulic Station, and what in particular it was related to a kind of Hydraulic Station goes out oil system.
Background technology
Hydraulic Station is the hydraulic power source being made up of hydraulic pump, drive motor, fuel tank, direction valve, choke valve, overflow valve etc.
Device or the hydraulic means including control valve.By the flow direction of driving means requirement, pressure and flow fuel feeding it is adaptable to drive
Device detached with Hydraulic Station various mechanically, by Hydraulic Station and driving means（Oil cylinder or motor）It is connected with oil pipe, hydraulic pressure system
System can achieve the action of various regulations.
The patent documentation of Publication No. CN203757347U discloses a kind of electric/manual one lubricating pump, in this technology
In scheme, electrodynamic pump and manual pump are integrated, thus realizing in the case of having electricity or power-off, all can normal work
Function.But in this technical scheme, there is not enough place, that is, oil pumps out by electrodynamic pump oil-out check valve and manually
After hydraulic fluid port check valve, it is directly connected to plant equipment, and oil-out check valve has a certain distance apart from oil-out, so being machine
After tool equipment has led to oil, in the oil pipe of oil-out check valve to oil-out, there is oil mass, thus leading to oil-out needs to be separated
During plant equipment（Plant equipment by or Hydraulic Station is damaged in the case of needing repairing）, extremely fuel-displaced positioned at oil-out check valve
Oil mass in the oil pipe of mouth can flow out, thus both having wasted oil mass, polluting environment again, therefore there is improved space.
Utility model content
For the deficiencies in the prior art, what this utility model provided a kind of Hydraulic Station goes out oil system, realizes in flowline
Oil effectively flowed back, to prevent it from flowing in environment, cause the situation of the wasting of resources and environmental pollution.
For achieving the above object, this utility model provides following technical scheme：
A kind of Hydraulic Station go out oil system, including manual pump module, electronic pump module and fuel tank, manual pump module includes handss
Dynamic pump oil outlet one-way valve, manual pump oil outlet one-way valve is connected with manual oil pump outlet line, and electronic pump module includes the fuel-displaced list of electrodynamic pump
To valve, electrodynamic pump oil outlet one-way valve is connected with electronic oil pump outlet line, and the mouth of pipe of manual oil pump outlet line is connected to electronic oil pump outlet line
On, it is characterized in that：Also include reversal valve and return duct, described reversal valve is installed on electronic oil pump outlet line, described return duct
One end is connected to reversal valve, and the other end is connected to fuel tank, and the mouth of pipe of described electronic oil pump outlet line is provided with stop valve.
By technique scheme, using reversal valve and return duct, the oil being located in flowline can be made to be back to fuel tank
In, the setting of stop valve simultaneously, also can further stop oil from flowing out from the mouth of pipe of flowline, thus ensure that effective profit of oil
With.
Preferably, described reversal valve is hand-operated direction valve.
By technique scheme, hand-operated direction valve also can be used when power is off.
Preferably, described reversal valve is solenoid directional control valve.
By technique scheme, solenoid directional control valve can conveniently control, thus facilitating the operation of staff.
Preferably, described stop valve is hand stop valve.
By technique scheme, hand stop valve also can be used when power is off.
