Description

Technical Field

[0001] This utility model relates to the field of airtightness testing technology, specifically to an integrated machine for testing the airtightness of gas cylinder filling. Background Technology

[0002] Air breathing apparatus is widely used in fire protection, chemical industry, shipbuilding, petroleum, metallurgy, warehouse, laboratory, mining and other departments to enable firefighters or rescue personnel to safely and effectively carry out fire fighting, rescue and relief work in various environments such as dense smoke, toxic gas, steam or oxygen deficiency. The testing and inspection of air breathing apparatus cylinders includes pressure verification of the airtightness of the cylinders.

[0003] According to a public announcement (CN117109816B) regarding an integrated gas cylinder filling and airtightness testing machine and its usage method, the space between the gas cylinder and the inner wall of the testing chamber is divided into several sealed chambers by a closed ring. Gas is then injected into the gas cylinder through a gas tube. If a leak occurs, the leaking gas enters different sealed chambers depending on its location, triggering markers on the upper and lower ring surfaces of the chambers to mark the outer surface of the gas cylinder. The area between two marked rings is the leak area. Compared to traditional water immersion and bubbling indicators, this zoned detection marking method allows users to accurately locate leaks. Furthermore, the markings facilitate subsequent processing after the gas cylinder is removed, and users can statistically analyze the leak area for process analysis, making it more practical for real-world use.

[0004] However, in actual use, although the above-mentioned equipment can make marks, it will leave marks on the outside of the bottle when making marks, which will cause the marks to spread when wiping the liquid later, thus affecting the appearance. In view of this, we propose an integrated gas cylinder filling and airtightness inspection machine. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated machine for testing the airtightness of gas cylinder filling, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gas cylinder filling and airtightness testing integrated machine, comprising a chamber, a water supply pipe provided on the outer wall of the chamber, a detection and dewatering assembly provided on the inner wall of the chamber, the detection and dewatering assembly comprising a storage plate, the storage plate being fixedly connected to the outer wall of the chamber, an angle ruler being fixedly connected to the outer wall of the storage plate, a scale sleeve being fixedly connected to the outer wall of the chamber, a movable ruler being slidably connected to the inner wall of the scale sleeve, a marking hole being provided on the outer wall of the movable ruler, and a perforated partition being fixedly connected to the inner wall of the chamber;

[0007] A connecting frame is detachably installed on the outer wall of the perforated partition. A base plate is fixedly connected to the end of the connecting frame, and a top plate is fixedly connected to the end of the connecting frame. A handle is fixedly connected to the outer wall of the top plate. A mounting frame is fixedly connected to the inner wall of the compartment, and a sponge board is fixedly connected to the outer wall of the mounting frame.

[0008] Preferably, the center lines of the top plate and the bottom plate are all on the same straight line as the center line of the scale sleeve.

[0009] Preferably, the number of connecting frames is two sets, and the two sets of connecting frames are arranged on both sides of the chassis center plane.

[0010] Preferably, the number of the perforated partitions is several, and the several perforated partitions are arranged in a linear array on the inner wall of the silo.

[0011] Preferably, the outer wall of the perforated partition is provided with a cleaning component, the cleaning component including a U-shaped frame, the U-shaped frame being fixedly connected to the outer wall of the perforated partition, and a sponge sleeve being fixedly connected to the outer wall of the U-shaped frame.

[0012] Preferably, the inner wall of the sponge sleeve is adapted to the outer wall of the connecting frame, so that the connecting frame can be wiped by the sponge sleeve when it is removed.

[0013] Preferably, the number of U-shaped frames is two sets, and the two sets of U-shaped frames are arranged on both sides with the center surface of the hollow partition as a mirror image.

[0014] Compared with the prior art, this utility model provides an integrated machine for testing the airtightness of gas cylinder filling, which has the following beneficial effects:

[0015] 1. This integrated gas cylinder filling and airtightness testing machine is used in daily operations. First, fill the chamber with water, then place the cylinder onto the base plate on the connecting frame. Next, hold the handle and lift the base plate, top plate, and connecting frame, inserting them into the chamber and the perforated partition. Finally, insert the gas supply pipe through the hole on the top plate to fill the cylinder. When air bubbles are generated, you can move the movable ruler. After the movable ruler moves to the location of the air bubble, you can finally determine the position of the air outlet hole on the marked hole and install the bolt. After determining the position of the air outlet hole, you can take out the connecting frame and the cylinder and place them on the storage plate. Determine the position of the air outlet hole according to the position of the movable ruler and the angle value displayed by the angle ruler. There is no need to re-mark the holes. When removing the connecting frame and the cylinder, the sponge plate on the mounting frame will wipe the outer wall of the connecting frame and the cylinder, which is convenient for subsequent cylinder testing and does not require wiping the water on the outside of the cylinder.

[0016] 2. In this integrated gas cylinder filling and airtightness testing machine, when the connecting frame and the cylinder body are removed so that the sponge plate on the mounting frame can remove the water adhering to the connecting frame and the cylinder body, the sponge sleeve set on the U-shaped frame will first wipe away the water adhering to the outer wall of the connecting frame, which can further improve the water removal effect on the outer wall of the connecting frame. Furthermore, when the chassis is pulled out, it will squeeze the sponge plate, allowing the accumulated water to flow down, ensuring the effectiveness of subsequent water removal.

An angle ruler 302 is fixedly connected to the outer wall of the storage plate 301. A scale sleeve 303 is fixedly connected to the outer wall of the chamber 1. A movable ruler 304 is slidably connected to the inner wall of the scale sleeve 303. A marking hole 310 is opened on the outer wall of the movable ruler 304. A hollow partition 305 is fixedly connected to the inner wall of the chamber 1.

[0024] Furthermore, the connecting frame 306 is detachably installed on the outer wall of the hollow partition 305. The end of the connecting frame 306 is fixedly connected to the base plate 307, and the end of the connecting frame 306 is fixedly connected to the top plate 308. The outer wall of the top plate 308 is fixedly connected to the handle 309. The inner wall of the compartment 1 is fixedly connected to the mounting frame 311, and the outer wall of the mounting frame 311 is fixedly connected to the sponge board 312.

[0025] In the embodiments of this utility model, the center line of the top plate 308 and the center line of the bottom plate 307 are all on the same straight line as the center line of the scale sleeve 303. There are two sets of connecting frames 306, and the two sets of connecting frames 306 are mirror images of the center plane of the bottom plate 307 on both sides. There are several hollow partitions 305, and the several hollow partitions 305 are arranged in a linear array on the inner wall of the compartment 1.

[0026] Furthermore, the outer wall of the perforated partition 305 is provided with a cleaning component 4, which includes a U-shaped frame 401. The U-shaped frame 401 is fixedly connected to the outer wall of the perforated partition 305. A sponge sleeve 402 is fixedly connected to the outer wall of the U-shaped frame 401. The inner wall of the sponge sleeve 402 is adapted to the outer wall of the connecting frame 306, so that the connecting frame 306 can be wiped by the sponge sleeve 402 when it is removed. There are two sets of U-shaped frames 401, and the two sets of U-shaped frames 401 are mirror images of the center plane of the perforated partition 305 on both sides.

[0027] In this invention, during daily use, water is first injected into the chamber 1, and then the bottle is placed on the base 307 on the connecting frame 306. Then, by holding the handle 309, the base 307, top plate 308, and connecting frame 306 are lifted and inserted into the chamber 1 and the perforated partition 305. Finally, the air supply pipe is inserted through the hole on the top plate 308 to inflate the bottle. When bubbles are generated, the movable ruler 304 can be moved.
