Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, specifically a safety valve with high safety. Background Technology

[0002] A safety valve consists of a body, valve seat, diaphragm, and spring. Under normal circumstances, the valve is in the closed state. When the pressure exceeds the set safety pressure, the valve will automatically open to release the excessive pressure and ensure the normal operation of the system. The safety valve can stably control the pressure of liquids or gases, ensure the smooth operation of the system, and improve work efficiency and quality.

[0003] When using existing safety valves, their function is to automatically open and reduce pressure in time in the event of an explosion or leak caused by overpressure in the pipeline, thereby reducing the harm of the accident. However, when the existing safety valves are inspected regularly, the lack of a wrench limiting structure makes it easy for the wrench to fail due to long-term disuse or changes in the operating environment, causing it to pop out and lead to an accident. Utility Model Content

[0004] The purpose of this utility model is to provide a highly safe safety valve to solve the problem mentioned in the background art that existing safety valves, when inspected regularly, lack a wrench limiting structure, which can easily cause the wrench to fail and pop out due to long-term disuse or changes in the operating environment, leading to accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety valve with high safety, comprising:

[0006] The safety valve body includes a valve body, a mounting port is provided on one side of the valve body, and a wrench is provided on one side of the top of the valve body;

[0007] The valve body has a limiting structure on its outer surface. The limiting structure includes a threaded ring, a positioning frame is sleeved on the outer wall of the threaded ring, a limiting ring is connected to one side of the positioning frame, a bearing is connected to the bottom end of the positioning frame, and a threaded sleeve is connected to the bottom end of the bearing.

[0008] Preferably, the threaded ring is fixedly connected to the outer surface of the valve body, and the limiting ring is configured as an annular structure.

[0009] Preferably, the bottom end of the wrench is inserted inside the limiting ring, and the positioning frame is sleeved on the outer wall of the threaded ring and slidably connected to the threaded ring.

[0010] Preferably, the limiting ring and the threaded sleeve are movably connected by a bearing, and the threaded ring and the threaded sleeve are rotatably connected by a thread.

[0011] Preferably, an adjustment mechanism is connected inside one side of the positioning frame. The adjustment mechanism includes a fixing rod, a positioning plate is sleeved on the outer wall of the fixing rod, a slide is connected to the top of the positioning plate, a fixing screw is inserted inside the slide, and a nut is rotatably connected to the outer surface of one end of the fixing screw.

[0012] Preferably, a groove is provided on one side of the top of the positioning frame, and the two ends of the fixing rod are connected to the two sides of the inner wall of the groove in the positioning frame. A through hole is provided on one side of the positioning plate, and the fixing rod is inserted into the through hole in the positioning plate and movably connected to the positioning plate.

[0013] Preferably, one end of the fixing screw is connected to one side surface of the threaded ring, and the other end of the fixing screw is inserted into the slide and slidably connected to the slide. The fixing screw and the nut are rotatably connected by threads.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By rotating the threaded sleeve to make it rotate with the outer surface of the threaded ring, the positioning frame moves with the threaded sleeve using the bearing without affecting the angle of the positioning frame. The limiting ring is then fitted onto the outer wall of the bottom end of the wrench, limiting the angle of the wrench so that it cannot change, thus locking it for subsequent maintenance and safety inspections. This prevents the wrench from failing due to long-term disuse or changes in the usage environment, which could lead to accidents.

[0016] 2. The positioning plate is moved and limited by the fixing rod. When the positioning frame is moved and adjusted, the angle of the slide is adjusted so that the slide is sleeved on the outer wall of the fixing screw. The fixing screw is used to position the slide. Then, the nut is rotated and connected to the outer surface of one end of the fixing screw. The nut is used to limit the angle of the slide. The distance between the nut and the threaded ring is adjusted to limit the slide, so that the positioning frame cannot move out of the sliding and fixing screw space. Attached Figure Description

[0027] A limiting structure 2 is provided on the outer surface of the valve body 11. The limiting structure 2 includes a threaded ring 21. A positioning frame 22 is sleeved on the outer wall of the threaded ring 21. A limiting ring 23 is connected to one side of the positioning frame 22. A bearing 24 is connected to the bottom end of the positioning frame 22. A threaded sleeve 25 is connected to the bottom end of the bearing 24.

[0028] Furthermore, the threaded ring 21 is fixedly connected to the outer surface of the valve body 11, and the limiting ring 23 is set as an annular structure to realize the angle limiting function of the bottom end of the wrench 13 through the limiting ring 23.

[0029] Furthermore, the bottom end of the wrench 13 is inserted inside the limiting ring 23, and the positioning frame 22 is sleeved on the outer wall of the threaded ring 21 and slidably connected with the threaded ring 21, so as to position the positioning frame 22 through the threaded ring 21.

[0030] Furthermore, the limiting ring 23 and the threaded sleeve 25 are movably connected by the bearing 24, and the threaded ring 21 and the threaded sleeve 25 are rotatably connected by the thread, so as to fix the threaded ring 21 and the threaded sleeve 25 by the thread.

[0031] Furthermore, an adjustment mechanism 3 is connected inside one side of the positioning frame 22. The adjustment mechanism 3 includes a fixing rod 31, a positioning plate 32 is sleeved on the outer wall of the fixing rod 31, a slide 33 is connected to the top of the positioning plate 32, a fixing screw 34 is inserted inside the slide 33, and a nut 35 is rotatably connected to the outer surface of one end of the fixing screw 34, so as to realize the movement limit of the positioning frame 22 through the movement space of the slide 33 and the fixing screw 34.

[0032] Furthermore, a groove is provided on one side of the top of the positioning frame 22, and the two ends of the fixing rod 31 are connected to the two sides of the inner wall of the groove provided in the positioning frame 22. A through hole is provided on one side of the positioning plate 32, and the fixing rod 31 is inserted into the through hole provided in the positioning plate 32 and is movably connected to the positioning plate 32, so as to realize the positioning of the fixing rod 31 through the through hole provided in the positioning plate 32.

[0034] Working principle: When the safety valve is being handled, the threaded sleeve 25 is rotated to rotate with the outer surface of the threaded ring 21. The bearing 24 is used to make the positioning frame 22 move with the threaded sleeve 25 without affecting the angle of the positioning frame 22. The limiting ring 23 is then fitted onto the outer wall of the bottom end of the wrench 13. The limiting ring 23 restricts the angle of the wrench 13, preventing it from changing, thus locking it for subsequent maintenance and safety inspection.

[0035] When adjusting the safety valve with high safety, the positioning plate 32 is moved and limited by the fixing rod 31. When adjusting the positioning frame 22, the angle of the slide 33 is adjusted so that the slide 33 is sleeved on the outer wall of the fixing screw 34. The fixing screw 34 is used to position the slide 33. Then, the nut 35 is rotated and connected to the outer surface of one end of the fixing screw 34. The nut 35 is used to limit the angle of the slide 33. By adjusting the distance between the nut 35 and the threaded ring 21, the slide 33 is limited, so that the positioning frame 22 cannot leave the moving space of the slide 33 and the fixing screw 34.
