[0035] The installation dimensions or port specifications of the servo valve may not match the actuator or system piping. The adapter block enables the connection between different components through customized internal flow channels and interface design.
[0036] The existing hydraulic testing process lacks safety protection measures. High-pressure oil may leak due to damage to the servo valve or disassembly before depressurization, posing a safety hazard.
[0037] This utility model proposes a hydraulic adapter block with safety protection function.
[0038] Please combine Figure 1 , Figure 2In one embodiment of this utility model, a hydraulic adapter block with safety protection function is proposed for connecting a servo valve. It includes an adapter block body 10, an oil inlet channel 11, an oil return channel 12, and a working channel that pass through the hydraulic adapter block body 10. The oil inlet channel 11 is provided with a blocking module for blocking the oil inlet channel 11. The adapter block body 10 is provided with an installation channel 15 that is connected to the oil inlet channel 11.
[0039] The blocking module includes a sealing plug 20 disposed in the installation channel 15, a transmission component 21 connected to the sealing plug 20, and a driver 22 connected to the transmission component 21; the driver 22 can drive the transmission component 21 and the sealing plug 20 to move along the length direction of the installation channel 15, and the sealing plug 20 can block the oil inlet channel 11.
[0040] In this embodiment, the adapter block body 10 has a cubic structure, including two opposite sides, namely a top surface and a bottom surface. The top surface is the mounting surface for installing the servo valve, and the bottom surface is used to connect hydraulic equipment. The oil inlet channel 11, the oil return channel 12, and the working channel are multiple independent fluid channels that run through the top and bottom surfaces. In this embodiment, there are two working channels, namely working channel A13 and working channel B14. By switching the valve core position of the servo valve, high-pressure oil or return oil is alternately introduced into working channel A13 and working channel B14, driving the actuator to reciprocate.
[0041] In some embodiments, the bottom surface of the adapter block body 10 can be connected to a hydraulic test bench to perform hydraulic tests on the servo valve. During the test, high-pressure oil leakage may occur due to various reasons, causing safety hazards. The blocking module can be automatically or manually triggered to respond quickly and block the oil inlet channel 11 when high-pressure oil leakage occurs.
[0042] Specifically, the main body 10 of the adapter block can be made of metal. Holes are drilled on the top surface according to the positions of the oil inlet channel 11, oil return channel 12, working channel A13 and working channel B14 of the servo valve. Then, holes are drilled on the top surface according to the positions of the oil inlet channel 11, oil return channel 12, working channel A13 and working channel B14 of the hydraulic equipment. Finally, multiple guide holes are drilled on the side of the main body 10 of the adapter block to connect the oil inlet channel 11, oil return channel 12, working channel A13 and working channel B14 on the top and bottom surfaces respectively. Then, the guide holes are sealed.
[0043] The installation channel 15 is a hole drilled from the side of the adapter block body 10 toward the oil inlet channel 11, and the installation channel 15 is connected to the oil inlet channel 11.
[0044] In one embodiment, after the installation channel 15 passes through the oil inlet channel 11, a blind hole is drilled forward, and the head of the sealing plug 20 can be inserted into the blind hole. The edge of the blind hole forms a step, which supports the sealing plug 20.
[0045] The sealing plug 20 is cylindrical, with a chamfer at its head. The chamfer serves as a guide, allowing the sealing plug 20 head to smoothly enter the blind hole. The diameter of the sealing plug 20 matches the inner diameter of the mounting channel 15, ensuring a tight fit between the sealing plug 20 and the mounting channel 15 and preventing oil leakage from the gap between them.
[0046] The transmission component 21 is a rod-shaped part. One end of the transmission component 21 is connected to the sealing plug 20, and the other end is connected to the driver 22. The transmission component 21 plays a transmission role, and the driver 22 is located outside the main body 10 of the adapter block.
[0047] The driver 22 can be a linear driver 22 that directly drives the transmission component 21 to reciprocate; or it can be a rotary driver 22 that, in conjunction with an eccentric structure, converts rotary motion into linear motion.
[0048] The plug 20 includes a blocked state and an open state; in the blocked state, the plug 20 completely blocks the oil inlet channel 11, and the oil at both ends of the oil inlet channel 11 cannot flow to each other; in the open state, the plug 20 does not completely block the oil inlet channel 11, and the oil at both ends of the oil inlet channel 11 can flow to each other.
[0049] The driver 22 can control the plug 20 to switch between the plugged and open states. In the open state, the main body 10 of the adapter block works normally, and in the plugged state, the oil inlet channel 11 is closed to prevent high-pressure oil leakage.
[0050] Furthermore, the driver 22 is a linear motor; a motor housing 25 is provided outside the mounting channel 15, one end of the transmission component 21 is connected to the sealing plug 20, and the other end of the transmission component 21 is connected to the linear motor;
[0051] The connection between the transmission component 21 and the linear motor is provided with the secondary magnetic conductor of the linear motor; the motor housing 25 is also provided with the primary winding of the linear motor and the motor controller connected to the primary winding; the motor housing 25 is provided with a motor control interface connected to the motor controller, and the transmission component 21 and the sealing plug 20 can be controlled to move along the length of the installation channel 15 within the installation channel 15 through the motor control interface.
[0052] In this embodiment, as Figure 3 , Figure 4 As shown, the driver 22 is a linear motor. A secondary magnetic conductor is provided at the connection between the transmission component 21 and the linear motor. A primary winding is located inside the motor housing 25. When energized, it generates an alternating magnetic field, creating a thrust on the secondary magnetic conductor. The motor controller is used to control the amplitude, frequency, and phase of the winding current. The motor controller is not shown in the figure.
[0053] Furthermore, an elastic element 23 is provided between the main body 10 of the adapter block and the sealing plug 20, and the elastic element 23 is used to push the sealing plug 20 to block the oil inlet channel 11;
[0054] The driver 22 can drive the transmission component 21 and the sealing plug 20 to move away from the oil inlet channel 11 and compress the elastic component 23.
[0055] In this embodiment, the elastic element 23 can be a compression spring. When the driver 22 is not working, the elastic element 23 pushes the sealing plug 20 to block the oil inlet channel 11.
[0056] In some embodiments, to prevent a malfunction in the blocking module control system that could cause the sealing plug 20 to remain open, a compression spring is used to keep the sealing plug 20 in a blocked state when the actuator 22 is not operating. When the blocking module control system is operating normally, it outputs a control signal to the actuator 22, pulling the transmission rod and the sealing plug 20 away from the oil inlet channel 11, thus opening the sealing plug 20 and simultaneously compressing the elastic element 23.
[0057] Furthermore, the hydraulic adapter block with safety protection function also includes a linear bearing 24 connected to the adapter block body 10. The transmission component 21 passes through the linear bearing 24, and the linear bearing 24 guides the displacement of the transmission component 21.
[0058] In this embodiment, the linear bearing 24 can be installed on the adapter block body 10 or on the motor housing 25. The transmission component 21 passes through the linear bearing 24, and the linear bearing 24 guides the transmission component 21.
[0059] Furthermore, a bushing 31 is provided inside the installation channel 15, and a portion of the sealing plug 20 remains in contact with the inner wall of the bushing 31 to prevent oil in the oil inlet channel 11 from leaking out of the installation channel 15.
[0060] In this implementation, such as Figure 6 As shown, the bushing 31 and the mounting channel 15 can be interference-fitted, and the inner wall size of the bushing 31 is precisely controlled so that it can fit tightly with the sealing plug 20.
[0061] Furthermore, the inner wall of the bushing 31 is provided with a limiting step 32, and the sealing plug 20 contacts the limiting step 32 in the open state, and the limiting step 32 provides support for the sealing plug 20.
[0062] In this embodiment, the sealing plug 20 is in an open state, and the high-pressure oil exerts a thrust on the sealing plug 20. The limiting step 32 forms a rigid limit and supports the sealing plug 20.
[0063] Furthermore, the hydraulic adapter block with safety protection function also includes a blocking controller, which is connected to the motor control interface;
[0064] The blocking controller is also equipped with a flow signal interface, which is used to input real-time flow information of the oil inlet channel 11 and / or the oil return channel 12 and / or the working channel.
[0065] In this embodiment, the blocking controller is used to process multiple preset hydraulic oil leakage judgment logics and multiple signal input flow signal interfaces. The blocking controller outputs control signals for controlling the driver 22 according to preset parameters.
[0066] In some embodiments, the flow information of the oil inlet channel 11 and the oil return channel 12 can be used to determine oil leakage. When the difference between the flow rate of the oil inlet channel 11 and the flow rate of the oil return channel 12 is greater than a preset value, it can be determined that oil leakage has occurred.
[0067] In some embodiments, the blocking controller is also provided with a pressure signal interface, which is used to input the pressure signal of the oil inlet channel 11. When the pressure of the oil inlet channel 11 drops rapidly and the rate of drop exceeds a preset value, it is determined that an oil leak has occurred.
[0068] In some embodiments, the hydraulic test bench can be used to acquire flow and pressure information of the oil inlet channel 11 and / or the oil return channel 12 and / or the working channel. The flow signal interface and the pressure signal interface can be connected to the hydraulic test bench to acquire response information.
[0069] Furthermore, flow meters are respectively installed on the oil inlet channel 11, oil return channel 12, and working channel of the hydraulic adapter block body 10; a signal output interface is also provided on the hydraulic adapter block body 10, which is connected to the flow meters on the oil inlet channel 11, oil return channel 12, and working channel for outputting flow signals.
[0070] In some embodiments, the main body 10 of the adapter block is provided with a flow sensor and / or a pressure sensor, and the main body 10 of the hydraulic adapter block is provided with a signal output interface. The signal output interface is connected to the flow meter and pressure gauge on the oil inlet channel 11, the oil return channel 12, and the working channel, and is used to output flow signals and pressure signals.
[0071] Furthermore, the main body 10 of the adapter block includes a mounting surface for mounting the servo valve, and the mounting surface is provided with an oil inlet connected to the oil inlet channel 11, an oil return port connected to the oil return channel 12, and a working port connected to the working channel;
[0072] The mounting surface is also provided with mounting holes for connecting the servo valve and mounting sensor 33 for detecting the installation status of the servo valve. The mounting sensor 33 is connected to the signal output interface.
[0073] In this embodiment, the mounting hole can be an internal threaded hole, and the servo valve is connected to the mounting surface by bolts. The mounting sensor 33 can be a micro switch. When the pressure in the oil inlet channel 11 is greater than a preset value, and the micro switch detects that the servo valve has been disassembled, it blocks the controller from outputting a control signal, thereby controlling the sealing plug 20 to block the oil inlet channel 11.
[0074] The sensor 33 can also be a pressure sensor. When the contact pressure between the servo valve and the mounting surface is less than the preset value or the pressure value shows a continuous decreasing trend, and the pressure in the oil inlet channel 11 is greater than the preset value, the controller outputs a control signal and controls the sealing plug 20 to block the oil inlet channel 11.
[0075] Furthermore, the hydraulic adapter block with safety protection function also includes a manual stop switch, which is connected to the stop controller.
[0076] In this embodiment, the manual blocking switch can be a manual emergency stop button. The manual blocking switch is connected to the blocking controller, and the operator can manually trigger the operation of the blocking plug 20 to block the oil inlet channel 11.
[0077] It should be understood that the terms "one embodiment" or "one example" throughout the specification mean that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in one example" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Those skilled in the art should also recognize that the embodiments described in the specification are optional embodiments, and the actions and modules involved are not necessarily essential to the present invention.
