Abstract
The invention discloses a one-way differential module capable of being completely cut off, which at least comprises a one-way valve, a high-pressure ball valve and a two-way plug-in direction valve, wherein the two-way plug-in direction valve is connected with the high-pressure ball valve through an oil port A, and the other end of the high-pressure ball valve is connected with a branch A1; the two-way cartridge directional valve is connected with the one-way valve through an oil port B, and the other end of the one-way valve is connected with a branch B1. The structural design of the differential module disclosed by the invention realizes a one-way differential function, namely, oil can only flow to the branch A1 from the branch B1 during differential operation, and cannot flow to the branch B1 from the branch A1. Meanwhile, the one-way valve has opening pressure, so that the two-way plug-in direction valve plug-in component can be better pressed in the pressure maintaining process of the hydraulic system, and the two-way plug-in direction valve is not easy to intermittently open due to pressure fluctuation of an X port or a Z port, so that the pressure maintaining function of the hydraulic system is more reliable, and the pressure maintaining effect is better.
Description
Technical Field
The invention belongs to the technical field of pressure maintaining of hydraulic control systems, and particularly relates to a one-way differential module capable of being completely cut off.
Background
At present, a pressure maintaining system comprising a one-way differential function module, such as a grinding roller loading hydraulic system of an upright mill, has the defects that the field environment is severe, the dust is large, the oil cleanliness is easily polluted, and small particle impurities easily enter the system in the operation process, so that the frequent blockage and failure of a shuttle valve hole of a shuttle valve in an element two-way plug-in direction valve cover plate and an element non-leakage electromagnetic ball valve are caused.
Meanwhile, in the pressure maintaining process of a pressure maintaining system, such as a vertical grinding roller loading hydraulic system, frequent impact exists in the system, so that a spring of an element two-way plug-in direction valve plug-in component in the two-way plug-in direction valve component fails.
The above causes the failure of the two-way plug-in directional valve assembly, i.e. the failure of the one-way differential function module, and in order to make the original pressure maintaining system continue to be used without using the one-way differential function, a one-way differential module capable of being completely cut off is needed.

The purpose of the invention is realized by the following technical scheme:
a one-way differential module capable of being completely cut off comprises at least one-way valve, a high-pressure ball valve and a two-way plug-in direction valve, wherein the two-way plug-in direction valve is connected with the high-pressure ball valve through an oil port A, and the other end of the high-pressure ball valve is connected with a branch A1; the two-way cartridge directional valve is connected with the one-way valve through an oil port B, and the other end of the one-way valve is connected with a branch B1.
According to a preferred embodiment, the two-way cartridge directional valve further comprises at least: the two-way plug-in mounting type directional valve comprises a two-way plug-in mounting type directional valve cover plate and a leakage-free electromagnetic ball valve, wherein a shuttle valve is further arranged in the two-way plug-in mounting type directional valve cover plate, a first selection port Z of the shuttle valve is connected with the high-pressure ball valve, a second selection port X of the shuttle valve is connected with a branch B1, and a working port.

Thus, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1
Referring to fig. 1, the invention discloses a completely cut-off one-way differential module, which at least comprises a one-way valve 1, a high-pressure ball valve 2 and a two-way plug-in direction valve. The two-way plug-in mounting directional valve is connected with the high-pressure ball valve 2 through an oil port A, and the other end of the high-pressure ball valve 2 is connected with a branch A1.
Therefore, through the structural arrangement of the high-pressure ball valve 2, when any component of the two-way cartridge directional valve fails, the differential module can smoothly complete the complete cut-off of the branch B1 and the branch A1, so that the hydraulic system can maintain the continuous operation of the original hydraulic system under the condition that the differential module is temporarily closed
Preferably, the two-way cartridge direction valve is connected with the check valve 1 through an oil port B, and the other end of the check valve 1 is connected with a branch B1.
Therefore, the one-way differential function of the module is realized through the structural arrangement of the one-way valve 1 in the module. That is, during the differential operation, the oil flows only from the branch B1 to the branch a1, but not from the branch a1 to the branch B1.
Preferably, the two-way cartridge directional valve further comprises at least: a two-way plug-in direction valve plug-in 3, a two-way plug-in direction valve cover plate 4 and a non-leakage electromagnetic ball valve 5.
A shuttle valve is further arranged in the two-way plug-in mounting direction cover plate 4, a first selection port Z of the shuttle valve is connected with the high-pressure ball valve 2, a second selection port X of the shuttle valve is connected with a branch B1, and a working port of the shuttle valve is connected with a control port of the two-way plug-in mounting direction valve through a non-leakage electromagnetic ball valve 5.
The pressure fluctuation of the hydraulic system is large during pressure maintaining, so that the two-way plug-in mounting directional valve component is intermittently opened, and the pressure maintaining effect is influenced. Because of the existence of opening pressure in the check valve 1, the pressure at the branch of B1 is higher than the pressure at the branch of B, so in the pressure maintaining process of the pressure maintaining system, the two-way cartridge direction valve plug-in 3 can be better pressed, the two-way cartridge direction valve is not easy to open intermittently because of the pressure fluctuation of the X port or the Z port, the pressure maintaining function of the hydraulic system is more reliable, and the pressure maintaining effect is better.
The foregoing basic embodiments of the invention and their various further alternatives can be freely combined to form multiple embodiments, all of which are contemplated and claimed herein. In the scheme of the invention, each selection example can be combined with any other basic example and selection example at will. Numerous combinations will be known to those skilled in the art.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
