[0002] Safety valves are special valves whose opening and closing parts are normally closed under the action of external forces. When the medium pressure in the equipment or pipeline exceeds the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. Safety valves belong to automatic valves and are mainly used in boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value, which plays an important protective role in personal safety and equipment operation. Note: Safety valves must undergo pressure tests before use.
[0003] When installing, most existing safety valves are fixed by flanges and bolts. However, most of the existing safety valves and bolts are exposed to the outside, and the bolts can be directly removed by tools, which is prone to the risk of theft. Utility Model Content

DETAILED DESCRIPTION
[0021] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a safety valve with an anti-theft function, including a safety valve body 1, a pipe 2 is arranged on the surface of the safety valve body 1, a flange 3 is fixed on the surface of the pipe 2, a shielding component 4 and a limiting component 5 are arranged on the surfaces of the pipe 2 and the flange 3, and the shielding component 4 includes: a disc 40, a spring 1 41, a through hole 42, a linkage 43, a slide groove 430, a limiting block 431, and a spring 2 432.
[0022] The disc 40 is penetrated by the pipe 2, and the disc 40 is slidably connected to the pipe 2. A spring 1 41 is fixed on the surface of the disc 40, and the end of the spring 1 41 away from the disc 40 is fixed to the surface of the flange 3. A through hole 42 is opened on the surface of the disc 40. The shielding component 4 also includes a linkage 43, and the linkage 43 includes a slide groove 430. The slide groove 430 is opened inside the through hole 42. The inner wall of the slide groove 430 is slidably connected to the limit block 431. A spring 2 432 is fixed on the surface of the limit block 431, and the end of the spring 2 432 away from the limit block 431 is fixed on the inner wall of the slide groove 430. Pulling the disc 40 will drive the limit block 431 to move synchronously, so that the disc 40 covers the flange 3, so that the bolts are covered and shielded, which can prevent the bolts from being directly exposed to the outside and the risk of theft.
[0023] The limiting assembly 5 includes a fixing rod 50, which is fixed on the surface of the pipe 2. The fixing rod 50 passes through the through hole 42. A groove 51 is provided on the side of the fixing rod 50 away from the pipe 2. A fixing block 52 is fixed to the inner wall of the groove 51. A sliding block 53 is slidably connected to the inner wall of the groove 51. A spring three 54 is fixed to the side of the sliding block 53 away from the fixing block 52. One end of the spring three 54 away from the sliding block 53 is fixed to the inner wall of the groove 51. When the disc 40 is pulled, the limiting block 431 is driven to move synchronously. The limiting block 431 can be limited by the fixing block 52, thereby stabilizing the disc 40. When maintenance is needed, the disc 40 is pulled again, the limit can be released by the sliding block 53, and the disc 40 is separated from the flange 3, and the bolts can be removed for maintenance.
[0024] The side of the limiting block 431 close to the flange 3 is configured as an inclined surface, and when being resisted, the limiting block 431 can enter the sliding groove 430 .
[0025] The side of the fixed block 52 and the sliding block 53 that is away from each other is set to be inclined, and the height of the sliding block 53 is higher than that of the fixed block 52. The inclined surface will not hinder the normal movement of the limit block 431. The height of the sliding block 53 is higher than that of the fixed block 52. When the limit needs to be released, the limit block 431 will fall from the surface of the sliding block 53 to the surface of the fixed block 52, thereby preventing the limit block 431 from colliding with the fixed block 52 again.
[0026] The disc 40 is set to be concave, so that the disc 40 can cover the flange 3 and prevent the bolts from being directly exposed to the outside.
[0027] When the safety valve body 1 needs to be installed, it is fixed by the flange 3 and the bolts. When the fixing is completed, the disc 40 is pulled on the side close to the flange 3, which will drive the limit block 431 to move synchronously, so that the disc 40 covers the flange 3, so that the bolts are covered and shielded, which can avoid the bolts being directly exposed to the outside and the risk of theft. At the same time, when the limit block 431 moves, its inclined surface will conflict with the surface of the fixed block 52, so that the limit block 431 enters the slide groove 430. When the side of the limit block 431 away from the inclined surface conflicts with the side of the fixed block 52 close to the sliding block 53, the fixed block 52 limits the limit block 431, thereby stabilizing the disc 40. When the safety valve body 1 is being inspected and repaired, the disc 40 is pulled again. At this time, the surface of the limit block 431 contacts the surface of the sliding block 53. When the limit block 431 is located on the side of the sliding block 53 away from the fixed block 52, under the action of the spring 1 41, the disc 40, the limit block 431 and the sliding block 53 are driven to move closer to the fixed block 52. When the surface of the sliding block 53 fits and contacts the surface of the fixed block 52, the limit block 431 moves along the surface of the sliding block 53, thereby falling on the surface of the fixed block 52, and then contacts the limit of the limit block 431. At this time, the disc 40 is separated from the flange 3, and the personnel can remove the bolts at this time to facilitate maintenance.
[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
