Technical Field

[0001] The utility model relates to the technical field of safety valves, and more specifically, to a new type of right-angle safety valve. Background Technique

[0002] A safety valve is in a normally closed state under the action of external force on the opening and closing member. When the medium pressure in the equipment or pipeline rises above the specified value, it prevents the medium pressure in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system. The safety valve belongs to the category of automatic valves and is mainly used on boilers, pressure vessels, and pipelines to control the pressure not to exceed the specified value, playing an important protective role in personal safety and equipment operation.

However, in actual use, the spring is damaged during the use process, resulting in the inability to accurately judge the current pressure during the pressure adjustment process. At the same time, due to the characteristics of the spring, the top end shakes during movement, easily causing the lead screw assembly to become loose, thereby affecting the pressure. Therefore, professionals in this field have provided a new type of right-angle safety valve to solve the above-mentioned problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0022] Please refer to Figures 1 to 4, in the present utility model, a new type of right-angle safety valve includes a safety valve body 1. An exhaust pipe 2 is integrally formed on the right side of the safety valve body 1. A movable plate 3 is slidably connected to the inner wall of the safety valve body 1. A sealing seat 4 is installed at the bottom of the movable plate 3. The sealing seat 4 is located on the left side of the exhaust pipe 2. A bearing plate 5 is slidably connected to the inner wall of the safety valve body 1. A pressure sensor 6 is fixedly installed at the bottom of the bearing plate 5. A magnetic block one 7 is installed at the bottom of the pressure sensor 6. A magnetic block two 8 is installed at the top of the movable plate 3. The magnetic block one 7 is located on the top of the magnetic block two 8 and is magnetically connected to the magnetic block two 8. A rotating shaft 9 is rotatably connected to the top of the safety valve body 1. The bottom end of the rotating shaft 9 penetrates and extends into the interior of the safety valve body 1. A threaded sleeve 10 is fixedly connected to the top of the bearing plate 5. The threaded sleeve 10 is threadedly connected to the rotating shaft 9. A limiting component 11 is arranged at the top of the safety valve body 1. A display 12 is installed at the top of the rotating shaft 9. A processor 13 is installed inside the safety valve body 1. The pressure sensor 6 and the display 12 are both in signal connection with the processor 13.

[0023] A limiting ring 16 is integrally formed on the inner wall of the safety valve body 1. The sealing seat 4 is located on the top of the limiting ring 16;

[0024] The limiting component 11 includes a limiting seat 1101. The limiting seat 1101 is sleeved on the rotating shaft 9. The bottom of the limiting seat 1101 is in contact with the top of the safety valve body 1. Uniformly distributed springs 1102 are fixedly connected to the inner wall of the limiting seat 1101. The top ends of the springs 1102 are fixedly connected to the rotating shaft 9;

[0025] A rubber sealing ring is arranged on the side of the sealing seat 4. The interior of the sealing seat 4 is in a hollow state.

[0026] The safety valve body 1 is installed at the installation position through a flange. Subsequently, the user can adjust the pressure of the sealing seat 4. The user holds the rotating shaft 9 with both hands and then pulls the bottom limiting seat 1101 upward with fingers. At this time, the spring 1102 is stressed and contracts, generating an opposite reaction force. The limiting seat 1101 separates from the top of the safety valve body 1. Subsequently, the user rotates the rotating shaft 9, and the threaded sleeve 10 threaded on the rotating shaft 9 starts to move downward. The bearing plate 5, the pressure sensor 6, and the first magnetic block 7 move downward accordingly. Since the magnetic poles of the first magnetic block 7 and the second magnetic block 8 are the same, they repel each other. The upward trend of the first magnetic block 7 can generate pressure on the pressure sensor 6. The pressure sensor 6 transmits the value to the processor 13, and the processor 13 displays the value on the display 12. The user can judge the current pressure according to the display 12. When the set pressure is reached, the user stops rotating the rotating shaft 9. At this time, the limiting seat 1101 is released, and the spring 1102 supports the limiting seat 1101. The bottom of the limiting seat 1101 fits against the top of the safety valve body 1, increasing the friction and preventing the rotating shaft 9 from rotating on its own. During operation, when the pressure inside the safety valve body 1 is greater than the pressure between the first magnetic block 7 and the second magnetic block 8, the sealing seat 4 pushes the second magnetic block 8 upward, while the bearing plate 5 remains stable. At this time, the value of the pressure sensor 6 increases, and the value on the display 12 changes. The sealing seat 4 moves upward, and the exhaust pipe 2 is exposed, realizing automatic exhaust. After the pressure value drops, the second magnetic block 8 can push the sealing seat 4 back to its original position to block the exhaust pipe 2.

[0027] In the present utility model, by arranging the first magnetic block 7 and the second magnetic block 8, the pressure on the sealing seat 4 is realized by the same magnetic poles between them, so that the sealing seat 4 blocks the exhaust pipe 2. When the internal air pressure of the safety valve body 1 is too high, the pressure overcomes the magnetic field effect, and the sealing seat 4 can be pushed up to discharge through the exhaust pipe 2, thereby realizing automatic pressure relief. At the same time, through the cooperation of the rotating shaft 9 and the threaded sleeve 10, the height of the first magnetic block 7 can be changed, thereby changing the pressure on the sealing seat 4. At the same time, during the operation of the safety valve and the process of adjusting the pressure, the pressure sensor 6 will display the pressure on the display 12 in real time, which is convenient for the user to view, making the pressure adjustment more accurate, and the user can also understand the internal pressure value of the safety valve body 1 to understand the equipment status and perform maintenance in a timely manner. Moreover, through the top limiting component 11, the stability of the rotating shaft 9 can be improved, and the rotating shaft 9 can be prevented from rotating on its own after adjustment.

[0028] Please refer to Figure 4 , in which: a status indicator light 14 is installed on the top of the safety valve body 1, and the status indicator light 14 is signal-connected to the processor 13.

[0029] In the present utility model, when the air pressure inside the safety valve body 1 is abnormal, the processor 13 will control the status indicator light 14 to flash, and the user can timely understand the internal status of the valve body through the status indicator light 14.

[0030] Please refer to Figure 2 , wherein: a guide shaft 15 is fixedly connected to the inner top wall of the safety valve body 1, and the bearing plate 5 is slidably connected to the guide shaft 15.

[0031] In the present utility model, the arrangement of the guide shaft 15 can restrict the bearing plate 5, so that the magnetic block one 7 and the bearing plate 5 always maintain stable movement in the vertical direction.

[0032] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improvement concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
