[0029] Reference Figs. 1-3 The utility model provides a kind of superimposed anti-shake double balance valve, including valve body 1, oil port A, pressure oil port P, oil port B, oil return port T and bolt mounting hole X are equipped on the valve body 1;
[0030] Wherein, valve body 1 inside is provided with balance valve insert 4 and its special oil port, which is connected with external oil port A, B, P, T, forms a closed hydraulic oil flow path;
[0031] Balance valve insert 4 is automatically adjusted open and close state according to the pressure of hydraulic oil, for realizing the anti-shake and smooth running of hydraulic system.
[0032] The embodiment realizes valve body structure: valve body 1 is made of high-strength alloy material, has good pressure resistance and corrosion resistance. Valve body 1 is equipped with four main interfaces: oil port A, pressure oil port P, oil port B, oil return port T and a plurality of bolt mounting holes X, for the connection and fixation with other hydraulic components.
[0033] Balance valve insert 4 is the core component of the utility model, it is installed in valve body 1, and is connected with oil passage in valve body 1 by special oil port. When the pressure of hydraulic oil reaches preset value, balance valve insert 4 can be automatically opened or closed, and the flow direction of oil is adjusted to maintain the stability of system pressure.
[0034] Work flow: when hydraulic system starts, pressure oil enters valve body 1 from P port, and then selects to pass through A or B port according to the demand of system. If the pressure of hydraulic oil exceeds the set threshold value of balance valve insert 4, insert is automatically opened, so that part of oil directly flows to T port through A or B port, to dampen the pressure fluctuation in system.
[0035] Adjustability and applicability
[0036] Adjustable setting: The set pressure value of the balance valve insert 4 can be adjusted, which means that the user can fine-tune the response point of the insert according to the actual hydraulic system requirements, achieving precise control of the system pressure. This flexibility enables the utility model to be widely used in various types of hydraulic equipment.
[0037] Optionally, the valve body 1 is also provided with a first process port sealing screw plug 2 and a second process port sealing screw plug 3 to ensure the sealing of the entire device and prevent hydraulic oil leakage.
[0038] It should be noted that the valve body 1 is provided with a first process port sealing screw plug 2 and a second process port sealing screw plug 3, which are made of high-temperature-resistant and oil-resistant rubber materials. By being fastened to a specific position on the valve body 1, the sealing of the entire device is ensured, and hydraulic oil leakage is avoided.
[0039] In an embodiment, the balance valve insert 4 is connected to the oil passage in the valve body 1 through a dedicated oil port and automatically opens when the hydraulic oil pressure reaches the preset value, allowing hydraulic oil to flow from the connection oil port A or B to the return oil port T.
[0040] In an embodiment, an O-shaped sealing element 5 is installed between the balance valve insert 4 and the valve body 1 to ensure their tight fit and enhance the overall sealing performance of the device.
[0041] It should be noted that the O-shaped sealing element 5 is installed between the balance valve insert 4 and the valve body 1 to ensure good sealing effect.
[0042] In an embodiment, when the hydraulic system is started, hydraulic oil enters the valve body 1 through the pressure oil port P and selects to pass through the connection oil port B or A according to the pressure of the hydraulic oil. When the hydraulic oil pressure reaches the set value of the balance valve insert 4, the balance valve insert 4 automatically opens. When the pressure of the hydraulic oil exceeds the set value of the balance valve insert 4, the balance valve insert 4 opens, allowing hydraulic oil to return to the return oil port T through the connection oil port A or B, thereby effectively controlling the pressure fluctuation of the hydraulic system.
[0043] In an embodiment, the valve body 1 is internally provided with multiple flow channels, and the multiple flow channels connect the oil port A, the pressure oil port P, the oil port B, and the return oil port T with the dedicated oil port of the balance valve insert 4, ensuring smooth flow of hydraulic oil in the valve body 1, reducing pressure loss and turbulence, and improving the response speed and stability of the system.
[0044] It should be noted that the valve body 1 is internally provided with multiple flow channels, and the multiple flow channels connect the oil port A, the pressure oil port P, the oil port B, and the return oil port T with the dedicated oil port of the balance valve insert 4. Such design not only ensures smooth flow of hydraulic oil in the valve body 1, but also reduces pressure loss caused by turbulence, improving the response speed and stability of the system.
[0045] By adjusting the set pressure value of the balance valve insert 4, precise pressure control is achieved to accommodate different hydraulic system requirements.
[0046] In one embodiment, the outer surface of the balance valve insert 4 is provided with anti-slip patterns or coatings.
[0047] It is worth noting that the outer surface of the balance valve insert 4 is specially treated with anti-slip patterns or coatings, which increases the friction force of the contact surface with the valve body 1, preventing displacement under high pressure.
[0048] Wherein, the set value of the balance valve insert is usually determined according to the specific hydraulic system requirements. The following are some common methods and steps for setting the set value of the balance valve insert 4:
[0049] Preparation: Close the hydraulic system and ensure safety. Prepare necessary tools such as wrench, pressure gauge, etc.
[0050] Disassembly and inspection: Remove the balance valve insert 4 and check for dirt or damage. Clean the insert and related oil lines.
[0051] Adjust the set value: Use the adjustment knob or special tools to gradually adjust the set value of the balance valve insert 4. After each adjustment, reinstall the insert and test the system.
[0052] Test the system: Turn on the hydraulic system and gradually increase the pressure. Observe the response of the balance valve insert 4. Record test data to ensure that the balance valve insert 4 works normally around the set value.
[0053] Final confirmation: In the running state of the system, continuously monitor the pressure fluctuation and system response. Confirm that the balance valve insert 4 can effectively suppress pressure fluctuations and maintain system stability.
[0054] Description: When the hydraulic system is started, hydraulic oil enters the valve body 1 through the pressure oil port P. Hydraulic oil enters the working circuit through oil port A or oil port B according to the demand of the system. When the hydraulic oil flows in the valve body 1, the balance valve insert 4 monitors the pressure in the oil circuit in real time. If the pressure of the hydraulic oil is lower than the set value of the balance valve insert 4, the insert remains closed, and the hydraulic oil continues to enter the working circuit through oil port A or B. When the pressure of the hydraulic oil reaches or exceeds the set value of the balance valve insert 4, the insert automatically opens, allowing part of the hydraulic oil to flow to the oil return port T through the connected oil port A or B. Through the automatic opening and closing of the balance valve insert 4, the pressure fluctuation of the hydraulic system can be effectively controlled. When transient high pressure occurs in the system, the balance valve insert 4 opens quickly to release excess pressure, preventing system overload and vibration. When the system pressure returns to normal, the balance valve insert 4 automatically closes to restore normal oil flow. In the system running state, the response of the balance valve insert 4 is observed by gradually increasing the pressure, ensuring that it works normally around the set value. Record the data during the test, including pressure value, flow rate and response time, etc. for subsequent analysis and optimization.

Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields based on the content of the present application specification and drawings, are also included in the patent protection range of the present application.
