Abstract

[0002] A gas cylinder is a portable pressure vessel mainly used for storing and transporting gases, including compressed gases, liquefied gases, dissolved gases, or adsorbed gases.

However, the pressure relief cannot be adjusted as needed, which makes it inconvenient to use.

[0033] Example 1
[0034] This embodiment provides a technical solution: a gas cylinder connection structure that facilitates pressure checking, such as... Figure 1 As shown, it includes a gas cylinder body 1, a gas cylinder main control valve 2, a pipeline connection mechanism, a pressure gauge 5, a hose clamping mechanism, and a gas regulating mechanism.
[0035] The main control valve 2 of the gas cylinder is installed and connected to the upper end of the gas cylinder body 1. The gas outlet at the upper end of the gas cylinder body 1 can be controlled to open and close through the main control valve 2, thereby controlling the gas discharge. The pipeline connection mechanism is installed and connected to the gas outlet of the main control valve 2. The pipeline connection mechanism can receive the gas discharged from the main control valve 2 and deliver it accordingly. The pressure gauge 5 is installed and connected to the inner side of the upper end of the pipeline connection mechanism. The pressure gauge 5 is exposed on the outside for easy personnel to check the pressure. The pressure gauge 5 can effectively detect the pressure inside the pipeline connection mechanism. The hose clamping mechanism is fixed to the lower end of the pipeline connection mechanism. The hose clamping mechanism can be placed on the lower side to clamp the hose connected to the pipeline connection mechanism and prevent the hose from loosening. The gas regulating mechanism is installed and connected to the right end of the pipeline connection mechanism. The gas regulating mechanism can be used to adjust the gas pressure discharge at the right end of the pipeline connection mechanism, so that corresponding adjustments can be made as needed.
[0036] The pipeline connection mechanism includes a gas cylinder valve connecting pipe 42, which is threadedly connected to the outlet end of the gas cylinder main control valve 2. The gas cylinder valve connecting pipe 42 can receive the gas discharged from the outlet end of the gas cylinder main control valve 2. A hollow conveying pipe 4 is fixedly connected to the right end of the gas cylinder valve connecting pipe 42, and the gas cylinder valve connecting pipe 42 can transport the received gas into the hollow conveying pipe 4. A tower-shaped gas outlet pipe 41 is fixedly connected to the lower right end of the hollow conveying pipe 4. The gas received inside the hollow conveying pipe 4 can be discharged through the tower-shaped gas outlet pipe 41. A hose clamping mechanism is installed on the outside of the tower-shaped gas outlet pipe 4 on the hollow conveying pipe 4. A gas regulating mechanism is installed on the right end of the hollow conveying pipe 4. Excessively high gas pressure inside the hollow conveying pipe 4 can be discharged through the gas regulating mechanism, thereby effectively ensuring safety during use.
[0037] The upper inner side of the hollow delivery pipe 4 is provided with a detection and installation hole corresponding to the pressure gauge 5, so that it can be installed and connected accordingly;
[0038] A rubber gasket is placed at the connection between the hollow delivery pipe 4 and the screw mounting plate 43, which makes the fixing tighter and more secure through the sealing of the rubber gasket.
[0039] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the gas regulating mechanism includes a screw mounting plate 43, which is mounted on the hollow delivery pipe 4 by screws, allowing for corresponding installation and connection. A pressure relief regulating pipe 62 is fixedly connected to the right end of the screw mounting plate 43. The screw mounting plate 43 can drive the pressure relief regulating pipe 62 to receive high-pressure gas inside the hollow delivery pipe 4. A pressure relief pipe 61 is fixedly connected to the middle of the lower end of the pressure relief regulating pipe 62. The high-pressure gas received inside the movable disc 63 can be discharged through the pressure relief regulating pipe 62, thus ensuring safety. A sealing disc 65 is sleeved inside the pressure relief regulating pipe 62, which can seal the slot of the pressure relief pipe 61, preventing the gas from being discharged randomly. Two strong springs 64 are fixedly connected to the right end of the sealing disc 65, providing elastic support for the sealing disc 65. A movable disc 63 is fixed to the right end, and a strong spring 64 can block the elastic support through the movable disc 63. The right end of the movable disc 63 is threadedly connected to a rotary hand valve 6 through the pressure relief regulating pipe 62. The movable disc 63 can block the support through the rotary hand valve 6 on the pressure relief regulating pipe 62. When the rotary hand valve 6 rotates forward on the pressure relief regulating pipe 62, the rotary hand valve 6 rotates outward on the pressure relief regulating pipe 62. The rotary hand valve 6 drives the position of the movable disc 63, the strong spring 64 and the sealing disc 65, thereby changing the distance of the sealing disc 65 blocking the exhaust from the pressure relief pipe 61. By changing the blocking distance, the distance that the sealing disc 65 moves under pressure will change, so the pressure relief can be adjusted as needed. During the adjustment, by measuring the distance between the rotary hand valve 6 and the pressure relief regulating pipe 62, the corresponding change in the pressure relief adjustment distance can be obtained.
[0040] The pressure relief pipe 61 is connected to the gas purification equipment pipeline, so that the discharged gas will not pollute the external environment.
[0041] During use, the gas outlet at the upper end of the gas cylinder body 1 can be controlled to open and close via the main gas cylinder control valve 2, thereby controlling the gas discharge. The pipeline connection mechanism can receive the gas discharged from the main gas cylinder control valve 2 and deliver it accordingly. The pressure gauge 5 is placed exposed on the outside for easy personnel to check the gas pressure. The pressure gauge 5 can effectively detect the gas pressure inside the pipeline connection mechanism. The hose clamping mechanism can be placed on the lower side of the pipeline connection mechanism to clamp the hose connected to the pipeline connection mechanism and prevent the hose from loosening. The gas regulating mechanism can be used to adjust the gas pressure discharge at the right end of the pipeline connection mechanism, allowing for corresponding adjustments as needed.
[0042] Example 2
[0043] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-3As shown, to further better realize this utility model, the following configuration is specifically adopted: The hose clamping mechanism includes a hollow sleeve 31, the upper end of which is fixedly connected to the hollow delivery pipe 4, and the hollow sleeve 31 can be suspended at the lower end of the hollow delivery pipe 4. A bottom sleeve rod 33 is sleeved on the inner side of the lower end of the hollow sleeve 31. The hollow sleeve 31 and the bottom sleeve rod 33 are fixedly connected by a locking bolt 32. When the personnel loosen the locking bolt 32, the bottom sleeve rod 33 can be adjusted in position inside the hollow sleeve 31, so that the clamping length can be changed and adjusted accordingly as needed. A suspension panel 3 is fixedly connected to the lower end of the bottom sleeve rod 33, and the bottom sleeve rod 33 can drive the suspension panel 3 to be suspended. A buckle groove 34 is provided on the inner side of the right end of the suspension panel 3. The suspension panel 3 can be correspondingly buckled in the externally connected air pressure hose through the buckle groove 34, thus preventing the air pressure hose from loosening due to gravity.
[0044] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
