Abstract
The utility model provides a multi-functional multipurpose valve group for an oil pump outlet. The multi-functional multipurpose valve group is suitable for the oil pump outlet of a hydropower station oil pressure unit or a hydraulic power unit. Loading and unloading of an oil pump are realized under the action of a one-way throttle valve or an electromagnetic valve. Safe overflow is realized under the action of a directly-operated overflow valve. Impact is reduced through a throttle valve. The multi-functional multipurpose valve group for the oil pump outlet replaces an existing product, improves the application function, reliability and control flexibility of a system, and can realize intermittent operation and continuous operation of the oil pump at the same time.
Description
Technical field
The utility model relates to a kind of multi-function oil pump outlet valve group that is applicable to water power plant oil gear or hydraulic power unit.
Background technique
Oil pump outlet valve group has a lot of existing products, but the requirement that all is not suitable for or does not meet oil pump intermittence or move continuously, and volume is large, cost compare is high, regulate loaded down with trivial details, impact greatly, the non-constant of cost performance is is therefore researched and developed a kind of the meet continuous operation of oil pump and intermittent duty and stable simultaneously, the requirement of easy to adjust, small impact, have again extremely urgent than the multi-function oil pump outlet valve group of high performance-price ratio.
Summary of the invention
The novel purpose of this reality is to provide a kind of multi-function oil pump outlet valve group that is applicable to water power plant oil gear or hydraulic power unit.The utility model is achieved through the following technical solutions: using cartridge valve for loading and unloading (1) as main body, its ingress is provided with pump intermittent duty time delay Loading Control valve (3), non-return device (4), the first pressure-detecting device (2) and the second pressure-detecting device (5), its control end has been installed safe overflow mechanism (8), pump moves loading and unloading control valve (6) and the 3rd pressure-detecting device (7) continuously, moves continuously at pump on the oil drain out of loading and unloading control valve (6) and is provided with action trimmer valve (9).
The utility model using standard cartridge valve (1) as the main body of loading and unloading function, with solenoid valve (6) realize continuous operation the loading and unloading function, realize time delay value-added tax function in intermittent duty, with moving relief valve (8) directly, realize safety protection function, with flange-type check valve (4), realize return-stopping function, with throttle valve (9), realize the protecting against shock function with one-way throttle valve (3); replaced existing product, made this model utility more be applicable to the requirement of power station pressurized oil system or pumping plant.
The utility model has the advantages that the combined type design by adopting various valve groups has met the requirement of the continuous operation of oil pump and intermittent duty simultaneously, there are flexible movements, impact step-less adjustment loading time delay little and can be stable, fully meet the demand of power station pressurized oil system or pumping plant.

Embodiment
As shown in Figure 1, a kind of multi-function oil pump outlet valve group, the loading and unloading of usining uses cartridge valve 1 as main body, its ingress is provided with pump intermittent duty time delay Loading Control valve 3, non-return device 4, the first pressure-detecting device 2 and the second pressure-detecting device 5, its control end has been installed safe overflow mechanism 8, pump moves loading and unloading control valve 6 and the 3rd pressure-detecting device 7 continuously, moves continuously at pump on the oil drain out of loading and unloading control valve 6 and is provided with action trimmer valve 9.
Oil pump for continuous operation, oil pump outlet pressure oil enters this device at the entrance of cartridge valve 1, now cartridge valve 1 is in opening state, oil is directly got back to fuel tank through the return opening of cartridge valve makes oil pump in the no-load running state, thereby through deferred action solenoid valve 6, make the logical pressure oil of control chamber of cartridge valve close the unloading port of cartridge valve, now pressure oil process check valve 4 is to system (or pressurized container) fuel feeding; The solenoid valve 6 that moves while reaching requirement when pressure (or oil transportation amount) makes the control chamber pressure of cartridge valve 1 lay down, and cartridge valve is opened, and the oil of oil pump is process again, and so forth next circulation.
For the intermittently used oil pump, oil pump outlet pressure oil enters this device at the entrance of cartridge valve 1, now cartridge valve 1 is in opening state, oil is directly got back to fuel tank through the return opening of cartridge valve makes oil pump in the no-load running state, through time delay (time of time delay can be carried out step-less adjustment by flow limit method 3) pressure oil by one-way throttle valve 3 control chamber that enters cartridge valve 1 gradually close the unloading port of cartridge valve, now pressure oil through check valve 4 to system (or pressurized container) fuel feeding; When pressure (or oil transportation amount), while reaching requirement, oil pump stops, and the control chamber pressure of cartridge valve 1 is laid down simultaneously, and cartridge valve is opened, and so forth next circulation.
No matter under any operating mode; under system breaks down the lasting situation about raising of pressure; directly moving relief valve action when pressure arrives the setting working value of straight moving relief valve 8; the pressure oil of the control chamber of cartridge valve 1 is laid down through the braking relief valve oil drain out that makes cartridge valve 1 and is opened; thereby delivery pressure is no longer raise, with protective system.
The utility model utilizes one-way throttle valve can accomplish the loading time delay step-less adjustment under oil pump intermittent duty operating mode, by throttle valve 9, make under the pump continuous working conditions pump unloading substantially without impact, and there is inlet pressure Check point 2, outlet pressure monitoring point 5 and pilot pressure monitoring point 7 and make debugging of the present utility model, maintenance and maintenance convenient.Be applied at present on gorge, Lechang governor oil pressure device and ball valve oil gear, respond well.
