[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Example:

[0024] Reference Figures 1 to 5 The utility model embodiment provides a fire valve air tightness detection device, which includes a shell 3, a moving wheel 1 is fixedly connected to the lower surface of the shell 3, a hinge is arranged below the shell 3, the shell 3 is rotatably connected to a transparent baffle 2 through the hinge, a first fixing mechanism 7 is fixedly installed on both sides of the shell 3, a fixed base 9 is fixedly installed on the bottom inner wall of the shell 3, a second fixing mechanism 10 is fixedly installed on the top of the fixed base 9, an installation groove is opened on the inner wall of the fixed base 9, a rubber seat 11 is movably connected to the inner wall of the installation groove opened on the inner wall of the fixed base 9, and a fire valve body 8 is movably connected to the top of the rubber seat 11.

[0025] The first fixing mechanism 7 includes a fixing washer 71, a shaft seat 72, a threaded rod 73, and a rotating disk 74. The inner wall of the shaft seat 72 is provided with a mounting hole, the inner wall of the mounting hole provided on the inner wall of the shaft seat 72 is movably connected with a fixing shaft, and the outer wall of the fixing shaft is rotatably connected with the threaded rod 73.

[0026] The diameter of the threaded rod 73 is greater than the length of the shaft seat 72 .

[0027] A fixing washer 71 is fixedly connected to one side of the threaded rod 73 away from the shaft seat 72 , and a rotating disk 74 is threadedly connected to one side of the fixing washer 71 away from the threaded rod 73 .

[0028] The second fixing mechanism 10 includes a fixing ring 101 and a fixing pin 102. The fixing ring 101 is fixedly connected to the upper surface of the fixing base 9. The inner wall of the fixing ring 101 is provided with a mounting groove. The inner wall of the mounting groove provided on the inner wall of the fixing ring 101 is movably connected with the fixing pin 102.

[0029] An air pump 4 is fixedly connected to a side of the housing 3 away from the transparent baffle 2 , and a hose 5 is fixedly connected to the top of the air pump 4 .

[0030] The output end of the hose 5 is fixedly connected with a pointed end 6, which is in the shape of a truncated cone with a wide top and a narrow bottom.

[0031] Among them, the threaded rod 73 can clamp the transparent baffle 2 and the shell 3, and the fixing pin 102 can pass through the mounting hole opened on the inner wall of the fixing ring 101 to fix the rubber seat 11. The rubber seat 11 is composed of a cylinder and a cuboid. One side of the cylinder of the rubber seat 11 can be clamped on the inner wall of the fire valve body 8. By setting the fixing ring 101 and the fixing pin 102, when the rubber seat 11 or the fire valve body 8 needs to be replaced, the fixing pin 102 can be pulled out from the mounting groove opened on the inner wall of the fixing ring 101, which is convenient for replacing the rubber seat 11 or the fire valve body 8.

At this time, the transparent baffle 2 is opened, and after all the water in the shell 3 flows out, the fixing pin 102 is pulled open to separate the fixing ring 101 from the fixing pin 102, and the fire valve body 8 fixedly connected to the rubber seat 11 is taken out from the mounting groove provided in the fixing base 9. The rubber seat 11 or the fire valve body 8 can be replaced. After the replacement is completed, the rubber seat 11 is clamped on the inner wall of the fire valve body 8, and the pointed head 6 is clamped on the inner wall of the fire valve body 8. After completion, the rubber seat 11 is placed in the installation groove opened in the fixed base 9, and the fixing pin 102 is inserted into the inner wall of the fixing ring 101. Close the transparent baffle 2, hold the rotating disk 74 and rotate the threaded rod 73 toward both sides close to the transparent baffle 2. The threaded rod 73 clamps the transparent baffle 2 and the shell 3, fills the shell 3 with water, starts the air pump 4, and detects the air tightness of the fire valve body 8 by observing whether there are bubbles in the water.
