Description
Technical field
The utility model is related to hydraulic control device field, especially a kind of piston oil-cylinder supplements delayed release device with oil pressure.
Background technology
Oil cylinder is a kind of conventional machinery device, and extremely wide is applied in a variety of mechanical equipments.In some lifting dresses
It sets, such as oil cylinder is also a kind of common lifting gear in stage field.
In the practical application of lifting gear, oil cylinder is vertically arranged more, in actual use, especially by stopping shape
Since the effect of the weight and piston dead weight of carrying object, cavity of resorption can discharge a large amount of energy suddenly during state to descending motion
Amount, is converted into instantaneous high pressure, and the release suddenly of so high pressure can not only cause the vibration during piston decline, when serious also
The damage that may lead to oil cylinder influences the safety used.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of lower cavity pressure slow release, epicoele
Hydraulic oil is supplemented, a kind of piston oil-cylinder for effectively solving piston oil-cylinder shake supplements delayed release device with oil pressure.
The utility model is achieved through the following technical solutions:
A kind of piston oil-cylinder supplements delayed release device with oil pressure, including an oil cylinder, the epicoele and cavity of resorption of the oil cylinder pass through respectively
Pipeline is connected with main oil pipe, it is characterised in that:A release of pressure is connected with by a branch pipe in the pipeline being connected to the cavity of resorption
Valve, a Fill valve is connected in the pipeline being connected to the epicoele by a branch pipe, and the pressure relieving valve and Fill valve pass through
Corresponding branch pipe is connected with an external fuel tank.
Moreover, being equipped with an overflow valve between the pipeline being connected in the cavity of resorption and the branch pipe for being equipped with pressure relieving valve.
Moreover, the pressure relieving valve and Fill valve are solenoid valve.
The advantages of the utility model and good effect are:
In the utility model, the cavity of resorption of oil cylinder is connected with external fuel tank by pressure relieving valve, when the mistake that the piston of oil cylinder falls
Cheng Zhong, due to the limitation of pressure relieving valve, the hydraulic oil being discharged by cavity of resorption can only slowly be discharged, therefore can prevent the hydraulic oil of lower intracavitary
A large amount of quickly discharges effectively play the effect of the hydraulic oil slow release of lower intracavitary, are trembled caused by prevent piston from hurtling down
Dynamic, epicoele is connected to external fuel tank by Fill valve, caused by piston falling speed can be prevented too fast the problem of epicoele vacuum, into one
Step improves stability and the safety of device;Overflow valve is connected with pressure relieving valve plays the role of level pressure overflow, is further ensured that
The safety and stabilization of device operation;Pressure relieving valve and Fill valve are all made of solenoid valve convenient for control.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
It elaborates to the utility model below by embodiment, the embodiment is illustrative instead of limiting
, protection scope of this utility model cannot be limited by this.
A kind of piston oil-cylinder supplements delayed release device with oil pressure, including an oil cylinder 1, the epicoele and cavity of resorption of the oil cylinder pass through respectively
Pipeline is connected with main oil pipe, and the innovation of the utility model is, is connected by a branch pipe in the pipeline 5 being connected to the cavity of resorption
Be connected to a pressure relieving valve 3, a Fill valve 7 be connected with by a branch pipe in the pipeline 6 being connected to the epicoele, the pressure relieving valve and
Fill valve is connected with an external fuel tank 4 by corresponding branch pipe.
In the present embodiment, an overflow is installed between the pipeline being connected in the cavity of resorption and the branch pipe for being equipped with pressure relieving valve
Valve 2.
In the present embodiment, the pressure relieving valve and Fill valve are solenoid valve.
The course of work of the utility model is:
When the utility model is used, when the piston of oil cylinder by static startup fall during, by control pressure relieving valve and
Fill valve is opened, and the hydraulic oil of oil cylinder cavity of resorption discharge is slowly discharged through pressure relieving valve, and cylinder upper cavity oil is then inwardly assisted by Fill valve
Supplement hydraulic oil.
In the utility model, the cavity of resorption of oil cylinder is connected with external fuel tank by pressure relieving valve, when the mistake that the piston of oil cylinder falls
Cheng Zhong, due to the limitation of pressure relieving valve, the hydraulic oil being discharged by cavity of resorption can only slowly be discharged, therefore can prevent the hydraulic oil of lower intracavitary
A large amount of quickly discharges effectively play the effect of the hydraulic oil slow release of lower intracavitary, are trembled caused by prevent piston from hurtling down
Dynamic, epicoele is connected to external fuel tank by Fill valve, caused by piston falling speed can be prevented too fast the problem of epicoele vacuum, into one
Step improves stability and the safety of device;Overflow valve is connected with pressure relieving valve plays the role of level pressure overflow, is further ensured that
The safety and stabilization of device operation;Pressure relieving valve and Fill valve are all made of solenoid valve convenient for control.
