Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, specifically to an ultra-high performance safety valve. Background Technology

[0002] A safety valve is an automatic pressure relief protection device that can automatically open to relieve pressure when the pressure in equipment or system exceeds a set value, preventing the pressure from continuing to rise and causing safety accidents.

[0003] The pressure at which a safety valve opens is called the set pressure. To ensure that the safety valve opens at the specified pressure, the set pressure of the safety valve needs to be adjusted. Manual adjustment requires close contact with the equipment. If the system pressure is unstable or the equipment leaks, it may cause burns, chemical burns or injury from high-pressure media spray, resulting in a low safety factor. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model discloses an ultra-high performance safety valve, including a safety valve body 1, a housing 2 at the upper end of the safety valve body 1, a pressure relief pipe 8 inside the safety valve body 1, a cover 9 fastened to the top of the pressure relief pipe 8, a column 11 at the upper end of the cover 9, a first cavity 10 at the top of the safety valve body 1, a pressure spring 12 inside the first cavity 10, and the column 11 inserted into the first cavity 10 with its top end contacting the bottom end of the pressure spring 12.

[0021] The top of the first cavity 10 is provided with a pressure plate 16, which is fixed to the upper end of the pressure spring 12. The upper end of the pressure plate 16 is provided with a docking block 15. The top of the housing 2 is provided with a rectangular rod 6, which passes through the housing 2 and is inserted into the interior of the first cavity 10. The bottom end of the rectangular rod 6 is provided with a second cavity 13, which is provided with a pressure sensor 14. The docking block 15 is inserted into the interior of the second cavity 13 and its top end contacts the detection end of the pressure sensor 14.

[0022] The rectangular rod 6 has a threaded groove, and a motor 4 is provided on the top of the housing 2. The output end of the motor 4 is provided with a threaded rod 7 that is inserted into the threaded groove and threadedly connected to the rectangular rod 6. The motor 4 is connected to the pressure sensor 14 via an electrical signal.

[0023] The motor 4 is a servo motor.

[0024] This safety valve achieves intelligent and precise adjustment of the set pressure through a closed-loop control system of pressure sensor 14 and servo motor. Its core working process is as follows:

[0025] Stress perception mechanism:

[0026] When the system pressure changes, the medium pressure acts on the baffle 9 and is transmitted to the pressure spring 12 through the column 11. The spring deformation causes the pressure plate 16 to shift, which in turn causes the docking block 15 to press against the pressure sensor 14. The sensor converts the mechanical signal into an electrical signal in real time and feeds it back to the control system.

[0027] Intelligent adjustment process:

[0028] The control system drives the servo motor to rotate forward and backward according to the preset pressure threshold. Motor 4, through the threaded transmission between the threaded rod 7 and the rectangular rod 6, precisely controls the position of the pressure plate 16 and dynamically adjusts the spring compression. When the system pressure approaches the set pressure, motor 4 automatically fine-tunes to ensure that the spring force is balanced with the medium pressure.

[0029] Pressure relief protection logic:

[0030] When the system pressure exceeds the set value, the medium pushes the baffle 9 upward, and the column 11 compresses the spring to open the pressure relief channel. After the pressure is released, the spring returns to its original position, pushing the baffle 9 to close, achieving automatic reset. Throughout the process, the pressure sensor 14 continuously monitors the spring state to compensate for performance drift caused by fatigue or temperature changes.

[0031] The motor 4 is fixed above the housing 2 by a support rod. The bottom end of the support rod is fixed to the top end of the housing 2 by screws. A protective shell 3 is provided above the housing 2. The motor 4 is located inside the protective shell 3. The bottom end of the protective shell 3 is fixed to the top end of the housing 2 by screws. The protective shell 3 and the sealing structure design effectively resist the damage to the motor 4 caused by harsh working conditions.

[0032] The upper end of the housing 2 is provided with a fixed seat 5, and the rectangular rod 6 passes through the fixed seat 5 and is slidably connected to the fixed seat 5. The cross-sections of the first cavity 10, the column 11, the docking block 15, the second cavity 13 and the rectangular rod 6 are all rectangular.

[0033] Rectangular cross-section components prevent rotational offset and ensure the stability of the transmission system.

[0034] Servo motors can achieve micron-level adjustment accuracy, and the pressure control error is significantly lower than that of traditional mechanical valves. Through real-time dynamic compensation of spring fatigue, the set pressure deviation can be effectively reduced during long-term use.
