Description
Technical field
The utility model relates to technical field of hydraulic equipment, specially a kind of novel hydraulic in hydraulic power station point
Flow valve block.
Background technique
Hydraulic power station is to provide the power unit of hydraulic power to hydraulic tools such as breakup pick, water pump, cast-cutting saws, for
For double loop or multiloop hydraulic power station, output flow is of different sizes, and hydraulic power unit currently on the market is generally
The variation of output flow is realized by duplex pump output flow or adjusting engine speed, duplex pump configuration not only increases
The structure size of power station also adds purchase cost, adjusts control of engine speed output flow and exists and is difficult to accurately to control
Revolving speed problem processed, while engine off-target rotary speed working state can be made and cause the phenomena such as insufficient that is short of power, burns,
Therefore it to realize various flow output, needs to design hydraulic system again.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of using based on three-way flowrate valve
Design shunts valve block for the novel hydraulic in hydraulic power station, can realize that various flow is defeated under rated engine speed
Out, and then multiloop function is realized.
The utility model is achieved through the following technical solutions:
A kind of novel hydraulic shunting valve block in hydraulic power station, including check valve, the first overflow valve, the second overflow
Valve, third overflow valve, three position four-way electromagnetic valve, three-way flowrate valve;The end a of the three position four-way electromagnetic valve connects A mouthfuls, the end b
By being separately connected B mouthfuls, C mouthfuls after the three-way flowrate valve, the end c connects P mouthfuls after passing through check valve, and the end d is connect with T mouthfuls, institute
The circulating direction for the check valve stated is the P mouthfuls of past ends c;The P mouth is connect by the first overflow valve with T mouthfuls, and the B mouth passes through
Second overflow valve is connect with T mouthfuls, and the C mouth is connect by third overflow valve with T mouthfuls;TA mouthfuls, TB mouthfuls, TC mouthfuls it is in parallel after with T
Mouth connection;The P mouth is hydraulic oil oil inlet, and the hydraulic oil pump feed under rated engine speed is entered by P mouthfuls;Described
T mouthfuls are hydraulic oil-returning mouth;The A mouth, B mouthfuls, C mouthfuls be flow delivery outlet, A mouthful are divided with TA mouthful, B mouthful and TB mouthfuls, C mouthfuls and TC mouthfuls
Cloth is formed into a loop to T mouthfuls of progress oil returns.
As an improvement of the above scheme, A mouth, B mouthfuls, C mouthfuls be equipped with quick-release connector, corresponding flow can be separately connected
Hydraulic tool.
It is exported the utility model has the following beneficial effects: meeting under rated engine speed big flow, while can also be with
Meet two small flow circuits simultaneously to use simultaneously, has both saved installation space, reduced manufacturing cost, while also meeting a variety of
The work requirements of hydraulic tool different flow.
Detailed description of the invention
Fig. 1 is that a kind of novel hydraulic in hydraulic power station of the utility model shunts the structural schematic diagram of valve block.
Description of symbols: check valve 1, the first overflow valve 2, the second overflow valve 3, third overflow valve 4, three position four-way electromagnetic valve 5, threeway
Flow valve 6.
Specific embodiment
Embodiment
As shown in Figure 1, a kind of novel hydraulic in hydraulic power station shunts valve block, including check valve 1, the first overflow
Valve 2, the second overflow valve 3, third overflow valve 4, three position four-way electromagnetic valve 5, three-way flowrate valve 6;The three position four-way electromagnetic valve 5
The end a connect A mouthful, the end b is separately connected B mouthfuls, C mouthfuls after passing through the three-way flowrate valve 6, and the end c is by connecting P after check valve 1
Mouthful, the end d is connect with T mouthfuls, and the circulating direction of the check valve 1 is the P mouthfuls of past ends c;The P mouth passes through the first overflow valve 2 and T
Mouth connection, the B mouth are connect by the second overflow valve 3 with T mouthfuls, and the C mouth is connect by third overflow valve 4 with T mouthfuls;TA
Mouthful, TB mouthful, TC mouthfuls parallel connections after connect with T mouthfuls;The P mouth is hydraulic oil oil inlet, the hydraulic pump under rated engine speed
Fuel feeding is entered by P mouthfuls;The T mouth is hydraulic oil-returning mouth;The A mouth, B mouthfuls, C mouthfuls be flow delivery outlet, A mouthfuls and TA
Mouth, B mouthfuls and TB mouthfuls, C mouthfuls and TC mouthfuls of distributions forming circuits are to T mouthfuls of progress oil returns.The A mouth, B mouthfuls, C mouthfuls be equipped with fast changing-over
Head can be separately connected the hydraulic tool of corresponding flow.
Working principle: three position four-way electromagnetic valve 5 controls the oil circuit output state of valve block, when three position four-way electromagnetic valve 5 is in
When middle position state, oil liquid enters after check valve 1 from P mouthfuls directly from T mouthfuls of circulation oil return boxes of reflux, A mouthfuls at this time, B mouthfuls, C mouth three
The equal unpowered output in road, equipment are in off working state.When three position four-way electromagnetic valve 5 is in left position, P mouthfuls of oil inlet quantities all by
A mouthfuls of outputs, system fuel delivery is maximum at this time, and big flow tool can be driven to participate in work.When three position four-way electromagnetic valve 5 is in right position
When, hydraulic oil flows to three-way flowrate valve 6, and three-way flowrate valve 6 has diverter function, may make B mouthfuls of output flows for fixed output
(firm discharge value can be set in advance as needed), extra flow are divided to C mouthfuls of oil circuits, and B mouthfuls, C mouthfuls thus can be made to export not
Same flow, B mouthfuls or C mouthfuls of roads external tool can use simultaneously, can also individually bonding tool use, extra oil liquid is through the second overflow valve 3
Or third overflow valve 4 flows back to fuel tank.The present embodiment can meet big flow under rated engine speed and export, while can also be simultaneously
Meet two small flow circuits to use simultaneously, both saved installation space, reduces manufacturing cost, while also meeting a variety of hydraulic
The work requirements of tool different flow.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
