Description

Technical Field

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

[0002] In the field of fire protection engineering, fire extinguishing valves, as core devices for fire prevention and emergency response, are widely used in fire protection systems of various buildings, industrial facilities, and public places. Their main function is to precisely control the flow and blockage of extinguishing agents (such as dry powder, water, and gas) to quickly respond to and initiate fire extinguishing operations when a fire occurs, effectively curbing the spread of fire and reducing loss of life and property. With the increasing intensification of modern buildings and the complexity of industrial production processes, higher demands are being placed on the response speed, ease of operation, and connection reliability of fire extinguishing valves. Especially in high-risk scenarios such as large complexes and chemical industrial parks, the performance of fire extinguishing valves directly affects the overall effectiveness of the fire protection system.

[0003] Existing fire extinguishing valves mostly employ traditional threaded or flanged connections. Threaded connections secure the valve by the helical engagement of the valve's interface with the pipe's external threads, relying on the tight fit of the threads to form a sealing surface and prevent extinguishing agent leakage. Flange connections, on the other hand, use flanges at the valve and pipe ends, bolts passing through flange holes and nuts tightened, causing the sealing gasket between the flange faces to deform and thus achieve connection and sealing. These connection methods have developed into mature technical systems through long-term engineering practice. Their principle is based on mechanical fastening and deformation sealing of the sealing material, ensuring the stability of the connection through static structural fit.

[0004] However, in existing technologies, traditional threaded connections require tools to rotate one turn at a time to complete assembly, while flange connections require tightening multiple bolts one by one. The entire installation process is cumbersome and time-consuming. In emergency situations, this complex assembly process often delays the rapid deployment of fire extinguishing valves and affects the emergency activation efficiency of the fire protection system. Therefore, a fire extinguishing valve that is easy to install is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a fire extinguishing valve that is easy to install, comprising a valve 1, a safety ring 2 on one side of the valve 1, the safety ring 2 being used to prevent the valve 1 from being accidentally operated, thereby improving the standby safety of the equipment, a fixing component being provided on the outer wall of the safety ring 2, a fixing pipe 3 being fixedly connected to the bottom of the valve 1, the fixing pipe 3 being used as the main connection structure, a connecting pipe 4 being slidably connected to the inner wall of the fixing pipe 3, and a quick-connect component being provided between the fixing pipe 3 and the connecting pipe 4, the quick-connect component being used to realize tool-free quick connection and fixation between pipes, thereby greatly improving the ease of installation;

[0035] The quick-release assembly includes multiple retaining balls 9, which are slidably connected to multiple grooves on the outer wall of the fixed tube 3. These retaining balls 9 engage with the grooves on the outer wall of the connecting tube 4. Driven by a slider 7, the retaining balls 9 move radially to lock or release the connecting tube 4, making them a key component for quick locking. The grooves on the outer wall of the fixed tube 3 have a structure that is larger in the middle and smaller at both ends. This structure limits the position of the retaining balls 9, ensuring sufficient movement for the locking action while effectively preventing them from falling off the fixed tube 3, thus maintaining the integrity of the assembly. A spring 8 is installed on the outer wall of the fixed tube 3, with one end of the spring 8 fixedly connected to the slider 7. The slider 7 is slidably connected to the outer wall of the fixed tube 3. The spring 8 provides continuous rebound force, ensuring that the slider 7 reliably resets after operation, thereby locking the retaining balls 9 and enhancing the stability of the connection. The other end of spring 8 is fixedly connected to a fixing block 6. The inner wall of fixing block 6 is fixedly connected to the outer wall of fixing tube 3. Fixing block 6 provides a stable fixed support point for spring 8, ensuring that spring 8 can effectively generate force. The outer wall of slider 7 is fixedly connected to a pushing block 5. Pushing block 5 provides a force-bearing surface that is easy to operate, allowing the operator to easily apply pushing force to compress spring 8, realizing a labor-saving and convenient unlocking operation. A connecting block 10 is fixedly connected to one side of the inner wall of pushing block 5. Pushing block 5 is slidably connected to the outer wall of fixing block 6. A fixing ring 17 is fixedly connected to the inner wall of fixing tube 3. The outer wall of fixing ring 17 fits against one end of connecting tube 4. Fixing ring 17 is used to accurately position the insertion depth of connecting tube 4, ensuring that the groove on the outer wall of connecting tube 4 can be accurately aligned with the locking ball 9, thus ensuring the connection quality.

[0036] Reference Figure 4 and Figure 5The fixing component includes multiple locking strips 12, which engage with the internal grooves of the safety ring 2. These strips are used to extend into or retract from the grooves of the safety ring 2, directly locking and unlocking the safety ring 2. This is the core component of the safety mechanism. A fixing shell 11 is fixedly connected to one side of the valve 1. This shell houses and protects the internal linkage mechanism of the entire fixing component, providing dust protection and preventing external impacts. A fixing block 14 is fixedly connected to the inner wall of the fixing shell 11. This fixing block 14 serves as a mounting base for multiple internal moving parts and a fixing end for the spring 16, ensuring the structural stability of the entire locking mechanism. Multiple connecting posts 18 are slidably connected inside the fixing block 14. Each connecting post 18 has a slider 15 fixedly connected to one end. The connecting posts 18 cooperate with the slider 15... 15 performs synchronous linear motion, achieving the effect of smoothly and evenly transmitting the pulling force of the pull block 13 to multiple locking strips 12. One side of the slider 15 is fixedly connected to one end of multiple locking strips 12. Each connecting post 18 is provided with a spring 16 on its outer wall. Each spring 16 is used to provide an independent reset force, ensuring that after the pull block 13 is released, each locking strip 12 can be quickly and reliably pushed back to the locked position, realizing the automatic locking function. One end of multiple springs 16 is fixedly connected to one side of the fixing block 14, and the other end of multiple springs 16 is fixedly connected to one side of the slider 15. The other end of multiple connecting posts 18 is fixedly connected to the pull block 13. The pull block 13 is used to provide a centralized operating point, which makes it convenient for the user to unlock the entire safety ring 2 with one hand, enhancing the ease of use in emergency situations.

[0037] Working Principle: During installation and connection, the operator first pushes the push block 5 upwards. Since the push block 5 is fixedly connected to the slider 7, this operation drives the slider 7 to slide upwards along the outer wall of the fixed tube 3. During this process, the slider 7 compresses the spring 8 between itself and the fixed block 6, causing the spring 8 to compress and store elastic potential energy. The removal of the slider 7 allows the multiple locking balls 9, which were originally radially locked, to move. Subsequently, the connecting tube 4 is aligned and inserted into the interior of the fixed tube 3. When the outer surface of the connecting tube 4 contacts the locking balls 9, it pushes the locking balls 9 inwards, into the pre-set groove on the wall of the fixed tube 3. This groove has a special structure that is large in the middle and small at both ends, which can both accommodate the movement of the locking balls 9 and prevent them from falling off. The connecting tube 4 is continuously pushed in until its end is in contact with the fixing ring 17 on the inner wall of the fixed tube 3. At this time, the annular groove on the outer wall of the connecting tube 4 is exactly aligned with the position of the locking balls 9. At this point, releasing the force on the pusher block 5 causes the previously compressed spring 8 to quickly rebound, pushing the slider 7 back to its original position. The inner inclined surface of the slider 7 then pushes the retaining ball 9 outwards, tightly locking it into the groove on the outer wall of the connecting pipe 4, thus achieving a quick and secure lock between the connecting pipe 4 and the fixed pipe 3. This achieves the goal of rapid assembly, solving the problems of cumbersome, time-consuming, labor-intensive, and tool-required installation of traditional threaded or flanged connections, and significantly enhancing the installation efficiency and connection reliability of fire extinguishing equipment in emergency situations.

[0038] When operating the fire extinguishing valve, the safety locking device must be released first. The operator pulls the pull block 13 outward, which, through the multiple connecting posts 18 connected to it, causes the slider 15 to slide outward inside the fixed housing 11. Since the slider 15 is fixed to multiple retaining strips 12 as one unit, the movement of the slider 15 causes the retaining strips 12 to be simultaneously pulled out of the grooves inside the safety ring 2. As the retaining strips 12 move outward, they cause the slider 15 to compress multiple springs 16 sleeved on the outside of the connecting posts 18. One end of these springs 16 abuts against the fixed block 14, and the other end abuts against the slider 15. Once the retaining strips 12 are completely disengaged from the safety ring 2, the safety ring 2 can be smoothly removed from the valve 1, allowing the valve to be operated. When not in use, releasing the pull block 13 will cause the compressed spring 16 to use its rebound force to push the slider 15 and the locking strip 12 to automatically reset, allowing the locking strip 12 to re-insert into the groove of the safety ring 2, thus completing the automatic locking. This achieves the function of effectively locking and quickly unlocking the safety ring, solving the problem that traditional safety pins are easily pulled out accidentally due to external factors. This ensures the safety of the fire extinguishing valve in the standby state and guarantees that it can be quickly activated in the event of a fire.
