Description

Technical Field

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

[0002] Fire dampers are valves installed on the supply and return air ducts of ventilation and air conditioning systems. They are normally open, but automatically close when the smoke temperature inside the duct reaches 70°C during a fire. They also meet smoke leakage and fire resistance integrity requirements for a certain period, thus serving as smoke and fire barriers. Fire dampers are often installed high up indoors, which makes installation dangerous and operation cumbersome.

[0003] An existing patent (publication number CN213451919U) discloses "a fire damper that is easy to install, comprising a housing with an air outlet and an air inlet at its two ends, and a sealing device for sealing the housing inside the housing. The housing is connected to the ceiling via a pre-positioning device, which includes a connecting rod, a positioning frame, and two positioning blocks. One end of the connecting rod is mounted on the ceiling, and the positioning frame is fixedly connected to the connecting rod, forming an installation space for placing the housing. The positioning blocks are rotatably connected to the positioning frame and located within the installation space, with the rotating surface of the positioning blocks being vertical. The housing is located in the installation space and placed on the upper surface of the positioning blocks, with the positioning blocks abutting against the positioning frame. This application has the advantage of facilitating workers to pre-position the housing between two pipes, allowing workers to install the housing between the two pipes using locking bolts and locking nuts."

[0004] In the process of developing this application, the inventors discovered the following problems with the existing technology: Although the aforementioned fire damper adopts a suspended structure to facilitate positioning with pipelines and thus make it easy to install, the installation process is still relatively cumbersome. Furthermore, it requires pre-installation at a high location, which is not only difficult to operate but also carries a high risk of accidents.

[0005] Therefore, those skilled in the art have provided a fire damper that is easy to install in order to solve the problems mentioned in the background art. Utility Model Content

[0024] 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.

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides an embodiment of a fire damper that is easy to install, comprising a fire damper body 1 and a base plate 23. A third hydraulic rod 21 is fixedly installed on the top of the base plate 23. A support plate 17 is fixedly installed at the output end of the third hydraulic rod 21. Side plates 9 are fixedly connected to both ends of the support plate 17. Two first-position limit rods 12 are slidably connected to both sides of the two side plates 9. A first-position limit block 10 is fixedly connected to the outer side of the two first-position limit rods 12. A first-position hydraulic rod 11 is fixedly installed in the middle of the two side plates 9. The two first-position hydraulic rods 11 and the four first-position limit rods 12 are fixedly installed on the inner side. There are two movable plates 15, and two second limit rods 14 are slidably connected to both sides of the two movable plates 15. A second limit block 16 is fixedly connected to the outer side of the two second limit rods 14. A second hydraulic rod 13 is fixedly installed in the middle of the two side plates 9. Two pressure plates 24 are fixedly installed on the inner side of the two second hydraulic rods 13 and the four second limit rods 14. Two insertion posts 18 are fixedly installed at the bottom of the two pressure plates 24. Fixed plates 5 are fixedly installed at the bottom of both sides of the fire damper body 1. Two insertion holes 6 are fixedly installed on the two fixed plates 5. The four insertion holes 6 and the insertion posts 18 are engaged.

[0026] Specifically, activating hydraulic rod 21 (number 3) raises support plate 17. Then, activating hydraulic rod 11 moves moving plate 15 horizontally under the control of limit rod 12, limiting its maximum movement distance via limit block 10. Activating hydraulic rod 13 moves pressure plate 24 horizontally under the control of limit rod 14, again limiting its maximum movement distance via limit block 16. Pressure plate 24 finally presses down on fixed plate 5, aligning insertion post 18 with insertion hole 6, thus firmly securing the fire damper body 1.

[0027] Reference Figure 4 , Figure 5 Push arms 22 are fixedly installed on both sides of the upper part of the base plate 23. The tail ends of the two push arms 22 are fixedly connected to handles 19. The four corners of the bottom of the base plate 23 are fixedly installed with casters 20. The top of the base plate 23 is fixedly installed with a control panel 25.

[0028] Specifically, by grasping the handle 19 on the push arm 22, the base plate 23 can be moved by the action of the moving wheels 20, and the control panel 25 can control the opening and closing of all hydraulic rods.

[0029] Reference Figure 1 , Figure 2 The fire damper body 1 has connecting flanges 2 fixedly installed on the front and rear sides, and multiple connecting holes 3 fixedly installed on the two connecting flanges 2. Rotary seats 7 are fixedly installed at both ends of the top of the fire damper body 1. The top of the two rotating seats 7 is rotatably connected to a clamping plate 8. Both connecting flanges 2 are threadedly connected to ventilation ducts 4.

[0030] Specifically, the fire damper body 1 and the ventilation duct 4 are connected by connecting flange 2. During the connection process, it is necessary to first roughly fix it, rotate the clamping plate 8 around the rotating seat 7 until it is locked at the ventilation duct 4.

[0031] Working principle: Place the fire damper body 1 onto the support plate 17. Operate the control panel 25 and activate the first hydraulic rod 11, causing the moving plate 15 to move horizontally under the limiting action of the first limiting rod 12. The first limiting block 10 restricts its maximum movement distance. Activate the second hydraulic rod 13, causing the pressure plate 24 to move horizontally under the limiting action of the second limiting rod 14. The second limiting block 16 restricts its maximum movement distance. The pressure plate 24 finally presses down on the fixed plate 5, with the insertion post 18 and insertion hole 6 corresponding one-to-one, thus firmly fixing the fire damper body 1. Then, grasp the handle 19 on the push arm 22 to move the base plate 23 under the action of the moving wheels 20, roughly moving the fire damper body 1 below the desired installation position. Then activate the third hydraulic rod 21 to raise the support plate 17 to the target height, allowing the person at the higher position to begin installation. Rotate the clamping plate 8 around the rotating seat 7 until it is locked at the ventilation duct 4, temporarily fixing it in place. Then you can start connecting the fire damper body 1 and the ventilation duct 4.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
