The deep-sea environment is characterized by high pressure, low temperature, high corrosion and darkness, which puts extremely high demands on the materials, design and manufacturing process of deep-sea equipment. Especially in deep-sea hydraulic systems, hydraulic valves are key components of the control system, and their performance directly affects the stability and reliability of the entire system.

DETAILED DESCRIPTION

[0026] Example 1

[0027] This embodiment provides a deep-sea hydraulic multifunctional valve box, comprising: a valve box body 1, a valve box cover plate 2, a plurality of hydraulic valve groups 3, a control circuit 4, and a throttle valve group 5.

[0028] like Figure 1As shown, the valve box body 1 is provided with an oil inlet port 6 and an oil return port 7; a pressure measuring port 11 is provided on the side of the oil return port 7. The valve box body 1 is also provided with a pressure reducing valve 10. The model of the pressure reducing valve 10 is BDBLAN. The valve box body 1 has at least one assembly surface 101 for installation. Multiple sets of sensor interfaces 8 are provided on the assembly surface 101.

[0029] The valve box cover plate 2 is detachably connected to the valve box body 1. The valve box cover plate 2 and the valve box body 1 are sealed by a sealing strip or the like. The valve box cover plate 2 covers the assembly surface 101, and a cavity is formed between the valve box cover plate 2 and the assembly surface 101.

[0030] Hydraulic oil is provided in the cavity. A compensation system interface 9 is provided on the side of the valve box cover plate perpendicular to the assembly surface 101. The cavity is connected to the external compensator through the compensation system interface 9, so that the hydraulic oil transmits pressure in the cavity; when the internal pressure changes, the hydraulic oil will transmit the pressure to the compensator through the cavity. The compensator makes corresponding adjustments according to these pressure changes.

[0031] The side surface of the valve box cover plate 2 parallel to the assembly surface 101 is set as a transparent structure 201; such a design not only enables the operator to monitor the situation inside the valve box in real time and intuitively, thereby ensuring the normal operation of the system; it also helps to promptly discover potential safety hazards, such as leakage or abnormal pressure, so as to quickly take measures to avoid potential accidents.

[0032] The valve box body 1 and the valve box cover plate 2 are made of corrosion-resistant and high-pressure-resistant alloy materials to ensure long-term stable operation in a deep-sea environment.

[0033] Multiple groups of hydraulic valve groups 3 are arranged in an array and installed on the assembly surface 101 and are located in the cavity. Each group of hydraulic valve groups 3 includes a balancing valve 31 and a reversing valve 32. The model of the balancing valve 31 is CBBCLHN. The model of the reversing valve 32 is BM4D32-G24-M35.

[0034] The throttle valve group 5 is mounted on the valve box body 1 and disposed below the assembly surface 101. The throttle valve group 5 includes a plurality of inlet throttle valves 51 and a plurality of outlet throttle valves 52. The model of the inlet throttle valve 51 and the outlet throttle valve 52 is NV08-20A.

[0035] The control circuit 4 is arranged in the cavity. The control circuit 4 is electrically connected to the hydraulic valve group 3 to control the working state of the hydraulic valve group 3. The control circuit is a solenoid valve circuit board, model BX13C01J-08-00A.
