Abstract
The utility model discloses a kind of new type of safe valve group for high pressure oil jacking device, is made of pilot operated compound relief valve, valve body, leakage oil export flange, pressure oil suction flange, pressure measuring tie-in, plug-in one-way valve, pressure oil outlet(discharge) flange.The new type of safe valve group, which can be realized, is precisely controlled the load of high pressure oil jacking device oil pump and unloading, have relief function and check function, unicoil electric controling mode is used in design, control is flexible, the oil pump of high pressure oil jacking device is unloaded when coil charges, oil pump loads when coil losing electricity, and the load time is controllable and accurate.The structure of the safe valve group of the utility model is simple, vdiverse in function, and control is accurate, can provide more reliable guarantee for the operation of entire high pressure oil jacking device.
Description
Technical field
The utility model is related to hydrogenerator field more particularly to a kind of new type of safe for high pressure oil jacking device
Valve group.
Background technology
High pressure oil jacking device is designed exclusively for hydraulic generator thrust bearing lubricating system, in unit starting and
High pressure oil is sprayed on axial thrust bearing surface when stopping, forming film lubrication.In existing high pressure oil jacking device, safe valve group
Complicated, debugging and maintenance difficulties are big, and it realizes that the control form of oil pump load and unloading is mechanical delayed version, this
Kind of control mode load time can not accurately set, and control accuracy is low, seriously affect entire high pressure oil jacking device safety, can
By work, the normal operation of unit is then influenced.In consideration of it, there is an urgent need for developing, one kind is simple in structure, is easy to debugging, control accuracy height
New type of safe valve group, provide more reliable guarantee for the work of high pressure oil jacking device.
Invention content
The purpose of this utility model is that a kind of structure for high pressure oil jacking device of development is simple, is easy to debug and tie up
The high new type of safe valve group of shield, control accuracy.The utility model is characterized in：Gone out by pilot operated compound relief valve 1, valve body 2, Leakage Energy
Mouth flange 3, pressure oil suction flange 4, pressure measuring tie-in 5, plug-in one-way valve 6, pressure oil outlet(discharge) flange 7 form, plug-in list
Into valve chamber of the valve 6 loaded on valve body 2, pressure oil outlet(discharge) flange 7 and pilot operated compound relief valve 1 are mounted on the top of valve body 2, Leakage Energy
Outlet(discharge) flange 3 and pressure oil suction flange 4 are mounted on the lower part of Leakage Energy outlet(discharge) flange 3.The utility model has the advantage of：
1, it is provided simultaneously with relief function and check function, reliability is high；
2, oil pressure relief is adjustable, is suitable for various working；
3, each valve block unit is integrated in one, simple in structure, is easy to debug and safeguard；
4, safe valve group ontology is equipped with 3 pressure measuring tie-ins, convenient for being measured to pressure；
5, it can accurately be set using unicoil electric controling mode, the load of oil pump and discharge time, control is flexibly and smart
Degree is high, is more advantageous to the work of oil pump, improves the service life of oil pump.
Description of the drawings
Fig. 1 is the front view of the safe valve group of the utility model
Fig. 2 is the vertical view of the safe valve group of the utility model
Fig. 3 is the hydraulic schematic diagram of the safe valve group of the utility model
Specific implementation mode
As shown in Figure 1 to Figure 3, the utility model is a kind of new type of safe valve group for high pressure oil jacking device, by
Pilot operated compound relief valve 1, valve body 2, Leakage Energy outlet(discharge) flange 3, pressure oil suction flange 4, pressure measuring tie-in 5, plug-in one-way valve 6,
Pressure oil outlet(discharge) flange 7 forms, in valve chamber of the plug-in one-way valve 6 loaded on valve body 2.Leakage Energy outlet(discharge) flange 3 is the valve in figure
The T chambers of group, pressure oil suction flange 4 are the P chambers of the valve group, and pressure oil outlet(discharge) flange 7 is the A chambers of the valve group.
Before high pressure oil jacking device electric motor starting, control electromagnetic valve coil electrification is oily at this time after motor operation
Pump is unloaded state, and P chambers are communicated with T chambers, and lubricating oil, which stays, pushes back power bearing oil groove；Oil pump under unloaded state according to program in set
After fixed operation a period of time time, electromagnetic valve coil dead electricity, oil pump starts run with load, the check valve 6 in safe valve group by
It gradually opens, P chambers are communicated with A chambers, and high pressure oil is sprayed on axial thrust bearing surface, form film lubrication；When oil feed line blocks
Or when the closing of high pressure oil jacking device internal valves, with the progress that oil pump loads, the pressure in pipeline can be increasing, when
After pressure reaches the setting value of pilot operated compound relief valve 1, P chambers communicate again with T chambers, and lubricating oil flows back to thrust bearing oil groove, with true
Protect the safety of entire high pressure oil jacking device.Three pressure measuring tie-ins 5 are connected with the b chambers of the safe valve group, c chambers and d chambers respectively,
For pressure measuring cavity, the operating pressure that external equipment is used for measuring safe valve group can be connected.
