Description
Technical field
The utility model relates to a kind of hydraulic directio control valve, particularly relates to a kind of two-way by the stroke valve.
Background technique
Present stroke valve both domestic and external is various informative, and mounting type is also various, but does not domesticly produce two-wayly by the stroke valve substantially, and the stroke valve base of producing originally is unidirectional stroke valve that ends and the two-way guiding valve that ends at present.
But originally all there are various shortcomings in these two kinds of stroke valve bases:
1) the unidirectional stroke valve that ends can only be realized unidirectional ending to the control of oil circuit.
2) two-wayly only be suitable for the low pressure oil circuit, have simultaneously and let out in bigger by guiding valve.
The model utility content
Technical problem to be solved in the utility model provides on a kind of hydraulic circuit by the two-way two-way stroke valve that ends by the oil circuit break-make of the energy of machinery control.
In order to address the above problem, what the utility model provided is two-way by the stroke valve, it is characterized in that: valve body is provided with the first oil circuit interface and the second oil circuit interface, on described valve body, be provided with the base and first Sealing thereof, in described valve body, be provided with first valve pocket and second Sealing thereof corresponding with the described first oil circuit interface, in described first valve pocket, be provided with first one-way valve, be provided with first spring between described first one-way valve and the described base, the described first one-way valve front end is provided with drive link, in described valve body, be provided with and the corresponding collision block of the described second oil circuit interface, in described collision block, be connected with second valve pocket and three Sealing thereof corresponding with the described second oil circuit interface, in described second valve pocket, be provided with second one-way valve, between described second one-way valve and described collision block, be provided with the 3rd spring, the drive link of described first one-way valve is corresponding with described second one-way valve, is provided with second spring between described first valve pocket and described second valve pocket.
Between described valve body and described collision block, be provided with dust ring.Between second valve pocket and the collision block with being threaded.First one-way valve and drive link are an integral body.First one-way valve and second one-way valve are independent part, and the first oil circuit interface on the valve body and the second oil circuit interface can be in valve body the same sides, also can be in valve body symmetry side.
Adopt the two-way of technique scheme, make collision block direction motion at the bottom of valve, drive second valve pocket and move with second one-way valve by external force by the stroke valve.Second one-way valve is with after the drive link of first one-way valve contacts, and the direction motion at the bottom of valve that continues along with collision block is all opened two one-way valve first one-way valves and second valve pocket in succession, connects the first oil circuit interface and the second oil circuit interface.After external force disappeared, first one-way valve, second valve pocket and collision block be return under first spring, second spring and the 3rd spring action, cuts off the first oil circuit interface and the second oil circuit interface again.The break-make of the two-way oil circuit of controlling by machinery on the realization hydraulic circuit that ends of energy.Dust ring is used to prevent dust.
In sum, the utility model is two-way by the stroke valve by the break-make of the two-way oil circuit that ends of energy of machinery control and simple in structure, easily manufactured, reliable performance on a kind of hydraulic circuit.
