Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a safety valve that is easy to install and adjust. Background Technology

[0002] A safety valve is a special valve whose opening and closing element is normally closed under external force. When the pressure of the medium in the equipment or pipeline rises above a specified value, it discharges the medium to the outside of the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Safety valves belong to the category of automatic valves and are mainly used in boilers, pressure vessels, and pipelines to control the pressure to not exceed the specified value. They play an important role in protecting personal safety and equipment operation, and therefore require installation and fixation when in use.

[0003] When installing existing safety valves, the connecting flanges at both ends are typically aligned with the connecting flanges at the ends of the pipeline and then secured with bolts. During this installation process, the flanges of both the safety valve and the pipeline need to be aligned, which requires manual verification by the operator. This is cumbersome. Furthermore, after aligning the flanges, when securing them with bolts, the mounting holes on the flanges also need to be aligned. That is, when installing one bolt, it is necessary to ensure that the mounting holes in other positions are not misaligned to avoid subsequent bolt installation problems.

[0004] Therefore, this utility model proposes a safety valve that is easy to install and adjust to solve the above problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a safety valve that is easy to install and adjust, including a safety valve body 1, with receiving pipes 11 on both sides of the safety valve body 1, and a first connecting flange 12 fixedly installed at the pipe opening of the receiving pipe 11. The receiving pipe 11 is connected to a connecting pipe 2, and a second connecting flange 21 is installed at one end of the connecting pipe 2. Both the first connecting flange 12 and the second connecting flange 21 are provided with mounting holes, and the first connecting flange 12 and the second connecting flange 21 are connected by a provided docking auxiliary component.

[0026] During the installation of the safety valve, the second connecting flange 21 at the end of the connecting pipe 2 is connected to the first connecting flange 12 at the end of the receiving pipe 11. During the connection, the limiting baffle 301 on the side of the first connecting flange 12 limits the second connecting flange 21, allowing the second connecting flange 21 and the first connecting flange 12 to be quickly aligned. The mounting holes of the second connecting flange 21 and the first connecting flange 12 are also aligned. That is, the limiting baffle 301 in the docking auxiliary assembly is symmetrically fixed on the side wall of the first connecting flange 12. The auxiliary baffle 302 is provided with a connecting through hole 303. One end of the auxiliary insertion pipe 304 is fixedly provided with a limiting retaining ring 305. The auxiliary baffle 302 is set as an arc-shaped plate, and there are two sets of auxiliary baffles 302. The two auxiliary baffles 302 are spliced ​​to form an auxiliary retaining ring. The connecting through hole 303 corresponds to the mounting hole in the first connecting flange 12 and the second connecting flange 21, and the hole diameter is equal.

[0027] After quickly connecting the first connecting flange 12 and the second connecting flange 21, the auxiliary insert 501 on the auxiliary baffle 302 is inserted into the auxiliary slot 503 at the end of the limiting baffle 301 until the auxiliary baffle 302 and the second connecting flange 21 are tightly fitted. At this point, the connecting through hole 303 in the auxiliary baffle 302 is aligned with the mounting hole in the second connecting flange 21. Next, to ensure the installation stability of the auxiliary baffle 302, the positioning screw 505 is threaded into the threaded groove 504 on the limiting baffle 301 until the positioning screw 505 is tightened. One end of the positioning screw 505 presses and fixes the auxiliary insert 501, and anti-slip teeth 50 are provided on the auxiliary insert 501. 2. It works in conjunction with the fastening protrusion 507 at the bottom of the positioning screw 505 to further enhance the squeezing and positioning effect on the auxiliary insert 501, thereby quickly completing the installation of the auxiliary baffle 302. The auxiliary insert 501 is fixedly set on the side wall of the auxiliary baffle 302, and anti-slip teeth 502 are equidistantly arranged on the auxiliary insert 501. The auxiliary slot 503 is set at the end of the limiting baffle 301, and the threaded groove 504 is set in the limiting baffle 301. The threaded groove 504 is connected to the auxiliary slot 503, and the threaded groove 504 is threadedly connected to the positioning screw 505. An auxiliary handle 506 is fixedly set at one end of the positioning screw 505, and a fastening protrusion 507 is set on the end face of the other end of the positioning screw 505.

[0028] By providing a limiting baffle 301 on the side wall of the first connecting flange 12, the first connecting flange 12 and the second connecting flange 21 can be quickly aligned. Specifically, the limiting baffle 301 is an arc-shaped baffle. When the second connecting flange 21 and the first connecting flange 12 are mated together, the side wall of the second connecting flange 21 contacts the inner side wall of the limiting baffle 301, achieving quick alignment. Subsequently, when connecting and fixing via the connecting threaded rod 401, to prevent the installation of one connecting threaded rod 401 from causing positional displacement of the mounting holes in other locations, this solution uses an auxiliary insertion tube 304 extending from the connecting through hole 30 on the auxiliary baffle 302. Insert the connecting rod 401 into the auxiliary tube 304, then pass it through the mounting hole in the second connecting flange 21, and then into the mounting hole in the first connecting flange 12. This provides a stabilizing effect for the mounting holes of the second connecting flange 21 and the first connecting flange 12, which are already aligned. Finally, pass the connecting threaded rod 401 through the auxiliary tube 304, and then connect it to the connecting threaded rod 401 with the stabilizing nut 402 to fix the first connecting flange 12 and the second connecting flange 21. This quickly completes the installation and fixing of the safety valve. The fastening components include the connecting threaded rod 401 and the stabilizing nut 402, which are threaded together.
