Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, and in particular to a safety valve body casting. Background Technology

[0002] As modern industry develops towards larger scale, greater complexity, and greater precision, many production processes need to be carried out under high pressure, high temperature, and high corrosiveness. In oil refining and cracking units in the petrochemical industry, supercritical and ultra-supercritical generator sets in the power industry, and gasifiers in the coal chemical industry, the operating pressure and temperature are constantly increasing, and the media are highly corrosive and flammable and explosive. Under these conditions, the pressure in the equipment and pipelines may rise abnormally for various reasons. This places higher demands on the performance of safety valve body castings, requiring them to withstand higher pressure and temperature, and to have good corrosion resistance and sealing performance to ensure timely and reliable opening and closing in emergency situations, protecting the safety of equipment and personnel.

[0003] During normal system operation, the automatic function can automatically adjust the opening and closing of the safety valve according to changes in equipment pressure, without frequent manual intervention, ensuring that the equipment pressure is always within a safe range and guaranteeing the stability and continuity of the production process. However, during equipment startup or shutdown, the safety valve needs to be opened or closed slowly by hand to control the rate of pressure rise or fall and avoid sudden pressure changes that could damage the equipment. During system debugging, maintenance, or testing, the safety valve also needs to be operated manually to accurately test its performance and check the equipment's pressure control. If automatic adjustment is not possible, and the equipment pressure rises abnormally above the set value, the safety valve may not open automatically to release pressure in time, causing the equipment pressure to continue to rise. This could lead to the equipment rupturing or exploding due to excessive pressure, resulting in serious safety accidents, personal injury, and property damage. If manual adjustment is also not possible, the last safety control measure is lost when the automatic function fails, and the risk of overpressure cannot be contained. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a safety valve body casting, which aims to improve the problem in the prior art that if the equipment cannot be manually and automatically adjusted, it will lead to equipment breakage and explosion, causing personal injury and property damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety valve body casting, comprising an outer shell, a hollow shell at the top of the outer shell, a fixing block fixedly connected to the top of the hollow shell, an mounting block fixedly connected to the top of the fixing block, air vents on both the left and right sides of the outer wall of the hollow shell, a rotating column rotatably connected to the inner wall of the mounting block, a fixing plate fixedly connected to the left side of the outer wall of the rotating column, an extrusion plate at the top of the inner wall of the outer shell, a U-shaped rod fixedly connected to the top of the extrusion plate, spring columns fixedly connected to both the left and right sides of the top of the extrusion plate, a connecting plate fixedly connected to the outer wall of the rotating column, and a sealing mechanism on both the left and right sides of the outer shell for sealing the equipment.

[0008] As a further description of the above technical solution:

[0009] A fixed column is fixedly connected to the front right end of the connecting plate, and limit rings are threadedly connected to the left and right sides of the outer wall of the rotating column.

[0010] As a further description of the above technical solution:

[0011] An anti-slip sleeve is fixedly connected to the right side of the outer wall of the connecting plate, and a base block is fixedly connected to the bottom of the outer shell.

[0012] As a further description of the above technical solution:

[0013] Triangular blocks are fixedly connected to the left and right sides of the outer wall of the shell, and lubrication rings are fixedly connected to the left and right sides of the inner wall of the fixed blocks.

[0014] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] A decorative block is fixedly connected to the left end of the front side of the outer wall of the flow tube, and a washer is provided on the outer wall of the screw.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the air pressure inside the flow pipe is too high, the extrusion plate will be pushed upward, compressing the spring column. When it reaches the air outlet, the gas will be discharged along the air outlet to reduce the pressure. After the pressure is reduced, the spring column will reset the extrusion plate. When manual adjustment is required, press the connecting plate to rotate the rotating column and the fixed plate, lift the U-shaped rod, and pull the extrusion plate to release the gas. This realizes manual and automatic adjustment of the air pressure inside the shell. The multi-functional adjustment facilitates the use of the user and improves the practicality of the equipment.

[0022] 2. In this utility model, rotating the screw allows it to pass through the hollow shell and enter the outer shell. The sealing gasket ensures the connection is sealed to prevent gas leakage. During installation, align the connecting ring and rotate it to complete the installation. The sealing ring ensures that the connecting ring and the installation point are sealed, facilitating gas passage. The sealing sleeve can seal the connection between the extrusion plate and the inner wall of the outer shell, achieving multi-faceted sealing of the equipment, providing sufficient guarantee for the normal passage of gas, and improving the accuracy of detection.

[0039] Working principle: When the gas pressure generated by the gas inside the flow pipe 201 is too high, it will push the extrusion plate 12 to move upward and squeeze the spring column 11. When the extrusion plate 12 moves to the position of the air outlet 6, the internal gas will be discharged through the air outlet 6 to reduce the internal gas pressure. After the gas pressure drops, the spring column 11 will push the extrusion plate 12 to reset. When manual adjustment is required, press the connecting plate 9 down. The connecting plate 9 will drive the rotating column 7 to rotate. During the rotation of the rotating column 7, the fixed plate 8 will rotate together, thereby lifting the U-shaped rod 10 upward. The U-shaped rod 10 will then pull the extrusion plate 12 upward to facilitate the release of internal gas. This realizes the manual and automatic adjustment of the internal gas pressure of the outer shell 1. The multi-functional adjustment facilitates the use of the user and improves the practicality of the equipment.

[0040] Tightening screw 202 allows it to pass through hollow shell 3 and enter outer shell 1. Sealing gasket 203 fully seals the connection between hollow shell 3 and outer shell 1, preventing gas leakage. During installation, align connecting ring 204 with the desired installation position and rotate to complete the installation. Sealing ring 205 seals connecting ring 204 with the installation location, facilitating normal gas flow. Sealing sleeve 206 seals the connection between extrusion plate 12 and the inner wall of outer shell 1, achieving multi-faceted sealing of the equipment and providing sufficient assurance for normal gas flow, thus improving detection accuracy.
