[0002] A marine fire valve pressure testing device is a specialized device for testing marine fire valves under water and air pressure. It is mainly used to test the sealing performance and pressure resistance of marine fire valves under different pressure conditions to ensure that they can work reliably in the ship's fire protection system.

[0003] In the prior art, when using a marine fire valve pressure testing device, the fire valve to be tested is usually placed in the designated position of the device first. Then, the corresponding test pipeline is manually connected, and the water and air sources are connected. The water or air pressure input is controlled by manually operating the valve. The state of the fire valve under different pressures is observed, and relevant test data is recorded. After the test is completed, the pipeline is manually disconnected and the fire valve is removed.

[0004] In existing technologies, switching between water pressure and air pressure testing requires frequent manual replacement of connecting pipes, which is cumbersome and affects testing efficiency. Therefore, a marine fire valve pressure testing device has been developed to address the aforementioned issues. Utility Model Content

[0023] 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.

[0024] Reference Figures 1-3This utility model provides an embodiment of a marine fire valve pressure testing device, including a support platform 1. A top plate 2 is fixedly connected to the outer wall of the support platform 1. The support platform 1 is the basic load-bearing structure of the entire device, used to install and fix various components. The top plate 2 cooperates with the through-mesh 618 to clamp and fix the fire valve. An outer support plate 3 is fixedly connected to the outer wall of the support platform 1. The outer support plate 3 provides a mounting support point for the motor 4, ensuring the stability of the motor 4 during operation. The motor 4 is fixedly connected to the outer wall of the outer support plate 3. The motor 4 provides the power source for the operation of the switching mechanism 5, driving the rotating shaft 511 to rotate. The extension end of the motor 4 is provided with the switching mechanism 5, which includes the rotating shaft 511. The rotating shaft 511 transmits the power of the motor 4, driving the connecting plate 512 to rotate. The rotating shaft 511 is fixedly connected to the output end of the motor 4 at one end. The extended end of the rotating shaft 511 is fixedly connected to the connecting plate 512. The elliptical structure of the connecting plate 512 allows it to alternately connect the air pump 513 and the water pump 514 to the fire valve connection port during rotation, while simultaneously squeezing the pressure frame 611. The air pump 513 is fixedly connected to the inner wall of the connecting plate 512. The air pump 513 is used to deliver gas to the fire valve for air pressure testing. The water pump 514 is fixedly connected to the inner wall of the connecting plate 512. The water pump 514 is used to deliver liquid to the fire valve for water pressure testing. A fixing mechanism 6 is provided at the bottom of the switching mechanism 5. The fixing mechanism 6 is used to fix the fire valve during pressure testing to prevent the fire valve from shaking. The connecting plate 512 is elliptical in shape.

[0025] Reference Figures 1-3The fixing mechanism 6 includes a pressure frame 611. The bottom of the pressure frame 611 is fixedly connected to the pressure frame 611. When the pressure frame 611 is pressed by the connecting plate 512, it will drive the telescopic rod 614 and other components to move together, thus fixing the fire valve. A limit rod 612 is provided at the bottom of the pressure frame 611. The limit rod 612 guides and limits the up-and-down movement of the pressure frame 611, preventing it from shifting. A spring 613 is fixedly connected to the bottom of the pressure frame 611. When the pressure frame 611 is not pressed, the spring 613 can drive the pressure frame 611 to return to its original position. The extension end is fixedly connected to the bottom of the inner wall of the support platform 1. A telescopic rod 614 is fixedly connected to the bottom of the pressure frame 611. The telescopic rod 614 can adjust the height of the through-mesh 618 by adjusting its length to accommodate different specifications of fire valves. The extension end of the telescopic rod 614 is hinged to a connecting rod 615. The connecting rod 615 plays a role in force transmission, converting the downward movement of the telescopic rod 614 into the upward movement of the connecting rod 619. A rotating rod 616 is rotatably connected to the inner wall of the connecting rod 615. The rotating rod 616 provides a fulcrum for the rotation of the connecting rod 615, ensuring smooth linkage of the connecting rod 615. The extension end of 6 is rotatably connected to the inner wall of the support platform 1. The extension end of the connecting rod 615 is hinged to a connecting rod 619. The connecting rod 619 can be adjusted in length to change its fixed height to accommodate different fire valve specifications. A mesh 618 is fixedly connected to the top of the connecting rod 619. The mesh 618 is used to place the fire valve and, together with the top plate 2, clamps the fire valve. A support rod 617 is fixedly connected to the bottom of the mesh 618. The support rod 617 provides auxiliary support to the mesh 618, enhancing its stability. The bottom of the support rod 617... The support rod 617 is fixedly connected to the bottom of the support platform 1. There are two support rods 617, which are symmetrically arranged at the bottom of the mesh 618. The outer wall of the connecting plate 512 contacts the outer wall of the pressure frame 611. The outer wall of the limiting rod 612 is slidably connected to the inner wall of the pressure frame 611. The outer wall of the support platform 1 is provided with a water outlet for discharging wastewater generated during the pressure test. The outer wall of the telescopic rod 614 is threaded with a fixing bolt 7. The fixing bolt 7 is used to fix the telescopic rod 614 after the length is adjusted to prevent the length from changing.

[0026] Working principle: The worker places the fire valve on the communication network 618. Then, depending on the type of fire valve requiring pressure testing (water pressure or air pressure), an electric motor rotates the elliptical disc at the output end. As the elliptical disc rotates, it switches the positions of the air pump 513 and water pump 514, connecting them to the fire valve's connection port for pressure testing. Simultaneously, when one end of the elliptical air pump 513 or water pump 514 rotates to the connection point, the bottom of the elliptical disc presses against the bottom pressure frame 611. When the pressure frame 611 is pressed, it causes the bottom telescopic rod 614 to move downwards. As the telescopic rod 614 moves downwards... The hinged connecting rod 615 moves downward, and at this time, the other end of the connecting rod 615 drives the hinged connecting rod 619 to rise upward, thereby fixing the fire valve placed on the mesh 618 between the top plate 2 and the mesh 618, thus ensuring the stability of the fire valve during pressure testing. When the height of the fire valve needs to be adjusted, the length of the connecting rod 619 is adjusted separately. The longer the telescopic rod 614 is, the lower it is pressed down, thus driving the mesh 618 hinged at the other end of the connecting rod 615 to rise higher. After adjustment, the telescopic rod 614 is fixed with the fixing bolt 7, which facilitates quick adjustment according to the specifications of the fire valve.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
