Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of safety valves, in particular to a fast-response oil pressure safety valve. Background Art
[0002] Hydraulic systems are widely used in various industrial fields, such as machinery manufacturing, oil extraction, chemical production, etc. These systems usually need to operate under high pressure, so safety issues are crucial. As an important protection device, the hydraulic safety valve can automatically open when the system pressure exceeds the safety range to release excessive pressure and prevent equipment damage or accidents.
[0003] Traditional oil pressure safety valves are mostly mechanically designed, relying on spring pressure to control the opening and closing of the valve. Due to the reliance on mechanical structure, traditional safety valves may not respond quickly when the pressure suddenly increases, thereby increasing the risk of the system. The elastic coefficient of the mechanical spring changes with the use time and environmental conditions, resulting in inaccurate pressure control. The complex mechanical structure often requires regular maintenance and calibration, increasing maintenance costs and downtime. Traditional safety valves usually do not have remote monitoring functions, and it is impossible to understand the working status of the valve in real time.
[0004] To this end, we provide a fast response oil pressure safety valve to solve the above problems. Utility Model Content

[0026] See also Figure 1-4 The utility model is a fast response oil pressure safety valve, comprising a safety valve body 1, and a control assembly 2 adapted to be installed with the safety valve body 1, wherein the safety valve body 1 comprises a valve body 11, a cover plate 12 detachably mounted on the side of the valve body 11, a flange port 13 integrally arranged at the end of the valve body 11, a valve core 14 movably arranged inside the valve body 11, and a pressure sensor arranged on the side of the valve core 14; the control assembly 2 comprises a connecting seat 21, a lower support 23 integrally arranged on the upper part of the connecting seat 21, an upper support 24 arranged above the lower support 23, a motor box 26 fixed at the middle position of the upper side of the upper support 24, a control box 28 connected to the motor box 26, a valve stem connected to the output shaft of the motor built in the motor box 26, and a control module arranged inside the control box 28.
[0027] Further description of the above structure includes: the inner side of the cover plate 12 is sealedly connected to the side opening of the valve body 11, and the outer side of the cover plate 12 has a convex layer extending outward.
[0028] A sealing layer 22 is clamped between the connecting seat 21 and the side opening of the valve body 11, and the valve stem passes through the connecting seat 21 and the valve body 11 to connect the valve core 14; a guide rod 25 is arranged between the edges of the lower support 23 and the upper support 24, and a spring 27 is arranged between the lower support 23 and the upper support 24, and a positioning seat 29 fixed at the end of the spring 27 is fixed to the middle of the lower support 23 and the upper support 24, and the valve stem passes through the spring 27 and the positioning seat 29.
[0029] A driving unit 210 is fixed to the upper end of the motor box 26, and the driving unit 210 is connected to a control module built into the control box 28; the control box 28 has a built-in independent power supply, and a display screen is embedded on the front of the control box 28. The control module built into the control box 28 is connected to a pressure sensor, and the control module is wirelessly connected to a management terminal.
[0030] The quick response oil pressure safety valve is mainly composed of two parts: a safety valve body 1 and a control component 2. In the safety valve body 1, the valve body 11 serves as the main body of the overall structure, and accommodates a movable valve core 14 inside. The cover plate 12 is detachably installed on one side of the valve body 11 and is sealed with the side opening of the valve body 11. Under the premise of not affecting its sealing performance, it is convenient for subsequent cleaning and maintenance of the inside of the valve body 11. A raised layer is also extended outward from the outer side surface as an anti-collision protection structure of the valve body 11. The flange port 13 is integrally formed at one end of the valve body 11 for connection with an external pipeline system. The valve core 14 is located inside the valve body 11 and is moved by controlling the valve stem to realize the opening and closing of the valve. The pressure sensor is installed on the side of the valve core 14 for real-time monitoring of the oil pressure in the system.
[0031] In the control assembly 2, the connecting seat 21 is connected to the side opening of the valve body 11, and a sealing layer 22 is provided between the two to ensure sealing. The lower support 23 and the upper support 24 form a supporting structure for installing the motor box 26 and other related components. The spring 27 is located between the lower support 23 and the upper support 24, and is used to provide a restoring force to help the valve core 14 reset. The positioning seat 29 is used to fix the two ends of the spring 27 to ensure the stability of the spring 27. The motor box 26 is installed on the upper support 24, and has a built-in motor, which is connected to the valve core 14 through a valve stem. The control box 28 has a built-in control module, an independent power supply, a display screen, etc., which is used to receive data from the pressure sensor and control the motor action based on this data, while providing a visual interface for user operation. The drive unit 210 is fixed to the upper end of the motor box 26 and is connected to the control module in the control box 28.
[0032] The steps for using the quick response oil pressure safety valve are as follows:
[0033] 1. Install the safety valve body 1 into the oil system to be protected through the flange port 13 , install the control assembly 2 , and ensure the sealing between the connecting seat 21 and the valve body 11 .
[0034] Second, set the working parameters of the safety valve through the display screen on the control box 28, such as the preset opening pressure value, and calibrate the pressure sensor to ensure its accuracy.
[0035] 3. Under normal working conditions, the valve core 14 is in the closed position, preventing the flow of oil. When the pressure in the oil system exceeds the preset value, the pressure sensor detects this change and transmits a signal to the control module. After the control module analyzes the signal, it activates the motor and moves the valve core 14 to the open position through the valve stem, thereby releasing the excessive oil pressure and protecting the system from damage. When the pressure drops to a safe range, the control module reverses the motor, and the valve core 14 returns to the closed position under the action of the spring 27, restoring the normal operation of the oil circuit. During this process, the control module can exchange data with the remote management end through the wireless communication module to achieve remote monitoring and adjustment.
[0036] In summary, the fast response oil pressure safety valve realizes effective protection of the oil system through integrated pressure sensor, motor control and remote communication functions, while providing convenient operation and maintenance methods.
