[0005] The purpose of the utility model is to solve the shortcoming in the prior art that it is difficult to quickly install and connect the device, and to propose a fire valve convenient for installation.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A fire valve convenient for installation, including a pipe body and a connecting device. Flanges are fixedly connected to both ends of the pipe body. A connecting plate is arranged on the surface of the pipe body. A rotating wheel is arranged at the upper end of the connecting plate. A connecting pipe is arranged at one end of the pipe body. The connecting device is arranged on the surface of the flange. The connecting device includes a first connecting ring and a second connecting ring. The first connecting ring is arranged at the connection of the pipe body and the connecting pipe. The second connecting ring is rotatably connected to the surface of the first connecting ring. A pulling groove is opened at one end of the first connecting ring. A clamping groove is opened on the side surface of the second connecting ring. A pulling plate is slidably connected to the inner wall of the pulling groove.

A clamping rod is fixedly connected to the surface of the pull plate. By providing the clamping rod, the first connecting ring and the second connecting ring can be connected, reducing the likelihood that the first connecting ring and the second connecting ring become loose during the use of the device, resulting in the first connecting ring and the second connecting ring detaching from the surface of the flange.

[0008] Furthermore, the clamping rod is clamped with the inner wall of the clamping groove, and a fixing groove is provided on the surface of the flange. The fixing groove is provided to facilitate the restriction of the fixing block.

[0009] Furthermore, a fixing block is fixedly connected inside the first connecting ring and the second connecting ring, and the fixing block is clamped with the inner wall of the fixing groove. The fixing block is provided to facilitate the restriction of the fixing grooves on the surfaces of the pipe body and the connecting pipe.

When the device is in use, the user pulls the pull plate, and when the pull plate moves, it drives the clamping rod to move. When the pull plate moves, it drives the first spring to displace and deform to generate elastic force. When the clamping rod moves, it disengages from the inside of the clamping groove. Then, the first connecting ring loses its restraint, and rotating the first connecting ring drives the fixing block to disengage from the inside of the fixing groove. Then, the connecting pipe loses its restraint. By setting the connecting device, the connecting pipe and the pipe body are effectively connected, playing a role in quickly and stably connecting the connecting pipe and the pipe body. When the device is in use, generally bolts are used to connect the pipe body and the connecting pipe, and the use of bolts requires tools for operation, and the use of tools is too cumbersome, resulting in a low work efficiency of the user. The practicability of the device is improved.

[0015] 2. In the present utility model, by setting the limiting device, when the device is in use, the user presses the pull rod downward, and when the pull rod moves, it drives the second spring to displace and deform to generate elastic force. Then, when the pull rod moves, it drives the limiting rod to move. When the limiting rod moves, it disengages from the inside of the limiting groove. Then, the rotating wheel loses its restraint. By setting the limiting device, the rotating wheel is effectively restricted, playing a role in restricting the rotating wheel. When the device is in use, since the rotating wheel is randomly exposed to the air, the rotating wheel is easily affected by external forces and rotates, moving the valve inside the device, resulting in a situation where it is difficult to close the valve of the device. The practicability of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to Figures 1-6 , the present utility model provides a technical solution: a fire-fighting valve convenient for installation, including a pipe body 1 and a connecting device 6. Flanges 2 are fixedly connected to both ends of the pipe body 1. A connecting plate 3 is arranged on the surface of the pipe body 1. A runner 4 is arranged at the upper end of the connecting plate 3. A connecting pipe 5 is arranged at one end of the pipe body 1.

[0024] Next, specifically describe the specific settings and functions of its connecting device 6 and limiting device 7.

[0025] In this implementation scheme: The connecting device 6 is arranged on the surface of the flange 2. The connecting device 6 includes a first connecting ring 61 and a second connecting ring 62. The first connecting ring 61 is arranged at the connection of the pipe body 1 and the connecting pipe 5. The second connecting ring 62 is rotatably connected to the surface of the first connecting ring 61. A pulling groove 63 is opened at one end of the first connecting ring 61. A card slot 64 is opened on the side surface of the second connecting ring 62. A pulling plate 65 is slidably connected to the inner wall of the pulling groove 63.

[0026] Specifically, one end of the pulling plate 65 is fixedly connected to a first spring 66. The end of the first spring 66 away from the pulling plate 65 is fixedly connected to the inner wall of the pulling groove 63. A card rod 67 is fixedly connected to the surface of the pulling plate 65.

[0027] In this embodiment: By setting the card rod 67, the first connecting ring 61 and the second connecting ring 62 can be connected, reducing the situation that the first connecting ring 61 and the second connecting ring 62 are prone to looseness during the use of the device, resulting in the first connecting ring 61 and the second connecting ring 62 being separated from the surface of the flange 2.

[0028] Specifically, the card rod 67 is clamped with the inner wall of the card slot 64. A fixed groove 68 is opened on the surface of the flange 2. The fixed groove 68 is provided to facilitate the limitation of the fixed block 69.

[0029] Specifically, a fixed block 69 is fixedly connected inside the first connecting ring 61 and the second connecting ring 62. The fixed block 69 is clamped with the inner wall of the fixed groove 68. The fixed block 69 is provided to facilitate the limitation of the fixed groove 68 on the surfaces of the pipe body 1 and the connecting pipe 5.

[0030] In this embodiment: A limiting device 7 is provided on the surface of the connecting plate 3. The limiting device 7 includes a pulling hole 71 and a limiting groove 72. The pulling hole 71 is opened on the surface of the connecting plate 3, and the limiting groove 72 is opened on the surface of the rotating wheel 4. A sliding rod 73 is fixedly connected inside the pulling hole 71. A pull rod 76 is arranged inside the pulling hole 71. A sliding hole 74 is opened on the surface of the pull rod 76, and the sliding rod 73 is slidably connected inside the sliding hole 74.

[0031] In this embodiment: By providing the sliding rod 73, the pull rod 76 can be limited in movement, reducing the situation that when in use, the pull rod 76 is prone to tilt, making it difficult to accurately insert the limiting rod 77 on the surface of the pull rod 76.

[0032] Specifically, a second spring 75 is sleeved and connected on the surface of the sliding rod 73. The two ends of the second spring 75 are respectively fixedly connected to the surface of the pull rod 76 and the inside of the pulling hole 71. By providing the second spring 75, it is convenient to apply a reset elastic force to the pull rod 76.

[0033] Specifically, a limiting rod 77 is fixedly connected to one end of the pull rod 76. The limiting rod 77 is clamped inside the limiting groove 72. By providing the limiting rod 77, it is convenient to limit the rotating wheel 4.

[0034] Working principle: When the device is in use, the user installs and connects the device to the pipeline, and then rotates the rotating wheel 4 to open the valve inside the pipe body 1. When the device is in use, the user pulls the pull plate 65. Then, when the pull plate 65 moves, it drives the clamping rod 67 to move. When the pull plate 65 moves, it drives the first spring 66 to displace and deform to generate an elastic force. When the clamping rod 67 moves, it disengages from the inside of the clamping groove 64. Then, the first connecting ring 61 loses its restraint, and rotating the first connecting ring 61 drives the fixed block 69 to disengage from the inside of the fixed groove 68. Then, the connecting pipe 5 loses its restraint. By providing the connecting device 6, the connecting pipe 5 and the pipe body 1 are effectively connected, playing a role in quickly and stably connecting the connecting pipe 5 and the pipe body 1, reducing the situation that when the device is in use, the pipe body 1 is generally connected to the connecting pipe 5 with bolts, and the use of bolts requires tools for operation, and the use of tools is too cumbersome, resulting in low work efficiency of the user, and improving the practicability of the device.

[0035] When the device is in use, the user presses down the pull rod 76. Then, when the pull rod 76 moves, it drives the second spring 75 to displace and deform to generate an elastic force. Then, when the pull rod 76 moves, it drives the limiting rod 77 to move. Then, when the limiting rod 77 moves, it disengages from the inside of the limiting groove 72. Then, the rotating wheel 4 loses its restraint. By providing the limiting device 7, the rotating wheel 4 is effectively limited, playing a role in limiting the rotating wheel 4, reducing the situation that when the device is in use, since the rotating wheel 4 is randomly exposed to the air, the rotating wheel 4 is prone to be affected by external forces and rotate, moving the valve inside the device, resulting in the situation that the device is difficult to close the valve, and improving the practicability of the device.
