Description

Technical Field

[0001] This utility model relates to the field of alarm valve technology, specifically to an alarm valve mounting and fixing structure. Background Technology

[0002] The alarm valve is a key control device in an automatic sprinkler system. It controls the flow of water to start and stop the fire extinguishing system. When a fire occurs, the detectors in the system detect the fire signal, and the alarm valve will open automatically, allowing water to flow into the sprinkler pipes. At the same time, it triggers the alarm device to send an alarm signal, notifying personnel to take timely measures. Its main function is to ensure that the fire extinguishing system can be started quickly and accurately when a fire occurs, while avoiding accidental spraying. It is an important piece of equipment to ensure the fire safety of buildings.

[0003] Alarm valves are typically installed in fire-fighting rooms, pump rooms, or corridors of buildings, in areas that are easy to operate and maintain. The environment should be free from freezing and corrosion risks, and the valves should be close to water supply pipes and sprinkler networks to ensure a rapid response in case of fire and to meet fire safety requirements. Alarm valves are usually fixed in place by flanges, which is a common installation method. During installation, the exposed thread pitch after the flange bolts are tightened should be 2 to 3 thread pitches.

[0004] When installing alarm valves, bolts are typically used to fix the valve flange to the pipe flange. While this connection method ensures stability after installation, in practice, each bolt requires precise adjustment of its exposed pitch to meet specifications. This process not only increases the complexity and difficulty of installation but may also extend installation time. Furthermore, the alignment of bolt holes, tightening sequence, and flange alignment all require high precision and meticulous adjustment, further increasing the technical requirements and labor intensity of installation. Therefore, to address these issues, an alarm valve installation and fixing structure is proposed. Utility Model Content

The first fixing auxiliary component 5 includes a first housing 51. A spring telescopic rod 52 is fixedly connected to the inner side of the first housing 51. A pressure-dividing fixing hole 53 is opened near the upper end of the first housing 51. A pressure-dividing fixing hole 53 is fixedly connected to the inner side of the pressure-dividing fixing hole 53. The pressure dividing fixing block 54 is fixedly connected to the bottom end of the pressure dividing fixing block 54 with a screw 55. The second fixing auxiliary component 6 includes a second housing 61. The lower end of the second housing 61 is provided with a dovetail annular groove 62.

The bottom end of the spring telescopic rod 52 is fixedly connected to the top end of the second housing 61.

[0030] As a further implementation of this solution, the top of the first flange 2 and the bottom of the second flange 3 are bonded together by a rubber ring. Both the first flange 2 and the second flange 3 are embedded in the inner side of the first housing 51. The inner side of the first housing 51 is bonded to the top of the second flange 3. The top view shape of the first housing 51 and the second housing 61 is a semi-circular structure. The front and rear ends of the second flange 3 are both equipped with the first fixing auxiliary component 5. Through the above settings, this structural design makes the installation process more stable. The bonding of the rubber ring can effectively prevent water leakage. At the same time, the semi-circular structure of the first housing 51 and the second housing 61 is easy to install and disassemble, improving the flexibility and convenience of installation.

[0031] As a further implementation of this solution, screws 55 are respectively inserted into the through holes of the first flange 2 and the second flange 3. The number of screws 55 is the same as the number of through holes of the first flange 2.

[0034] As a further implementation of this solution, the second sleeve 61 has a shaft hole on its inner side near the sleeve 66. The sleeve 66 is rotatably connected to the shaft hole of the second sleeve 61 via a limiting ring 69. The inner side of the sleeve 66 is hollow and extends beyond the lower end of the second sleeve 61. The outer side of the outer gear ring 67 meshes with the inner side of the inner gear ring 64. The inner gear ring 64 is arc-shaped. The shape of the dovetail ring block 63 and the opening shape of the dovetail ring groove 62 are both dovetail shapes. The bottom end of the inner gear ring 64 is fixed. The fixed connection has a throttle 65, and the number of the second fixed auxiliary components 6 is set to two sets, with two second fixed auxiliary components 6 in each set.

[0035] Workflow: To fix the alarm valve body 1 to the pipeline, first align the first flange 2 of the alarm valve body 1 with the second flange 3 of the pipeline. Pull the first housing 51 and the second housing 61, causing them to move in opposite directions. At this time, the second housing 61 drives the piston rod of the spring telescopic rod 52 to move. Simultaneously, there will be a certain gap between the nut 68 and the screw 55. Then, fit the first fixing auxiliary component 5 at the rear end onto the outside of the first flange 2 and the second flange 3, aligning the screw 55 with the through holes of the first flange 2 and the second flange 3. Then, loosen the first housing 51 and the second housing 61. Under the elastic tension of the spring telescopic rod 52, the first housing 51 and the second housing 61 move closer to each other. At this time, the screw 55 is inserted into the through hole of the first flange 2 and the second flange 3, and the lower end of the screw 55 enters the interior of the nut 68. The external thread of the screw 55 is in contact with the upper end of the internal thread of the nut 68. Following the same principle, the other first fixing auxiliary component 5 and the second fixing auxiliary component 6 of the same group are installed. At this time, the two first housings 51 and the two second housings 61 in the same group are in contact, and the dovetail grooves 62 of the two second housings 61 in the same group are aligned. Then, the first fixing auxiliary component is installed. 5. The second fixed auxiliary component 6 is fixed to the outside of the first flange 2 and the second flange 3. Rotating the handle 65 drives the internal gear ring 64 to rotate. The internal gear ring 64 is rotatably connected to the dovetail ring groove 62 opened in the second housing 61 through the dovetail ring block 63. When the internal gear ring 64 rotates, it will drive the inner meshing external gear ring 67 to rotate. At this time, the rear internal gear ring 64 enters the dovetail ring groove 62 at the front end. The rear internal gear ring 64 will push the front internal gear ring 64 to rotate. A ring is formed between the two internal gear rings 64. When the two internal gear rings 64 rotate, they will simultaneously drive multiple external gear rings 67 to rotate. The external gear rings 67 are rotatably connected to the second housing through the limiting ring 69. Inside 61, the external gear ring 67 drives the sleeve shell 66 and the nut 68 to rotate simultaneously. Since the inner side of the nut 68 is spirally fitted with the outer side of the screw 55, when the nut 68 rotates, the nut 68, sleeve shell 66 and the second sleeve shell 61 will move upward until the top of the nut 68 is fitted with the bottom of the first flange 2, and the installation is completed. At this time, the lower end of the thread of the screw 55 is exposed at the lower end of the nut 68, with 2 to 3 thread pitches. Based on the above principle, when installing the alarm valve body 1 and the pipeline, the device not only improves the installation efficiency and reduces the labor intensity, but also ensures the consistency of the thread left by the screw 55 after installation, reduces the technical requirements for the workers, and improves the qualification rate after installation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
