Description

Technical Field

[0001] This utility model belongs to the technical field of gas cylinder caps, and more specifically, it relates to a gas cylinder leak-proof cap. Background Technology

[0002] In industrial production and gas storage and transportation, gas cylinders, as commonly used gas storage containers, are widely used in industries such as chemical, medical, and energy to facilitate the storage and transportation of various gases. However, gas cylinders on the market suffer from problems such as poor sealing performance and a lack of effective pressure regulation mechanisms. If the top of the gas cylinder is not protected, it is easily affected by external environmental corrosion and impacts, leading to gas leakage and causing serious negative impacts on production safety and the environment. To avoid these problems, cylinder caps are used. However, traditional devices usually have large pressure relief holes, which cannot provide a precise seal on the top of the gas cylinder, increasing the risk of gas leakage, affecting gas quality and storage life, and reducing the safety of gas cylinder use. In addition, traditional devices lack adjustable structures for pressure relief and sealing. If adjustments cannot be made according to the actual situation after pressure leakage, the pressure inside the cylinder cap may become too high, which has an adverse effect on the gas cylinder and the usage scenario, reducing the applicability and reliability of traditional devices.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 3 As shown, this utility model provides a leak-proof cap for gas cylinders, including a gas cylinder body 11. The gas cylinder body 11 provides a solid container base for storing gas, enabling users to safely store gas and improving the reliability of the device. An integrally formed mounting base 12 is formed on the top of the gas cylinder body 11, and a gas cylinder valve 13 is internally threaded onto the mounting base 12. Users can conveniently install and remove the gas cylinder valve 13 through the integrally formed mounting base 12 on the top of the gas cylinder body 11, making the device easy to maintain and operate, improving the operability of the device, and enhancing the convenience of user operation.

[0025] A first sealing gasket 14 is provided between the gas cylinder valve 13 and the mounting base 12, which can effectively enhance the sealing between the two, so that users do not have to worry about gas leakage when using the gas cylinder, thus improving the sealing performance of the device. A gas cylinder cap 15 is provided on the gas cylinder valve 13, and a second sealing gasket 16 is provided between the gas cylinder cap 15 and the mounting base 12. Users can use the second sealing gasket 16 to ensure a good sealing effect, so that the device can work stably in various environments, thus improving the environmental adaptability of the device. Both the first sealing gasket 14 and the second sealing gasket 16 are made of rubber, ensuring that the sealing gaskets maintain stable sealing performance during long-term use, so that the device can effectively prevent gas leakage for a long time, thus improving the reliability of the device.

[0026] The gas cylinder cap 15 is surrounded by multiple sets of reflective stickers 17, which serve as warnings in low-light environments, allowing users to spot the cap even in low-light conditions, thus improving the device's safety. The cap 15 also features multiple integrally formed rotating lugs 102, allowing users to tighten the cap, making operation more convenient and efficient. Each lug 102 has anti-slip textures 103, increasing friction and preventing slippage, thus improving operational stability. The cap 15 also includes a label slot 104 for attaching a label 18, facilitating label installation and providing clear information about the gas cylinder, enhancing the device's information labeling function.

[0027] like Figures 2 to 5 As shown, the gas cylinder cap 15 has multiple sets of pressure relief holes 101, which are symmetrically arranged to release pressure in a timely manner when the internal pressure of the cylinder is abnormal, making the use of the gas cylinder safer and improving the safety performance of the device. Each set of pressure relief holes 101 is equipped with an adjustment component, which the user can adjust to control the degree of pressure relief, so that the device can adapt to different pressure conditions, improving the adaptability of the device and enhancing the user's flexibility in pressure control.

[0028] The adjustment assembly includes a mounting baffle 21, which is located on one side of the pressure relief hole 101. The mounting baffle 21 can block and guide the pressure relief process, making the pressure relief more orderly and improving the stability of the device. Multiple sets of guide rods 22 are integrally formed on one side of the mounting baffle 21, providing stable guidance for the movement of the mounting baffle 21, making the movement of the mounting baffle 21 precise and reliable, and improving the working accuracy of the adjustment assembly. The multiple sets of guide rods 22 are respectively set inside the gas cylinder cap 15. A pressure relief baffle 23 is elastically connected to one side of the mounting baffle 21. The pressure relief baffle 23 can adjust its position according to pressure changes, making the pressure relief more reliable and improving the practicality of the device.

[0029] The pressure relief baffle 23 is located on one side of the pressure relief hole 101. This structure allows for a rapid response when pressure relief is needed, enabling quick pressure release and improving the device's emergency response capability. An adjusting rod 24 is located above the pressure relief baffle 23. The position of the pressure relief baffle 23 is adjusted by the threaded connection between the adjusting rod 24 and the gas cylinder cap 15, allowing the device to flexibly control the pressure relief amount according to actual needs. This improves the adjustability of the device and enhances the user's accuracy in pressure control. One end of the adjusting rod 24 passes through the gas cylinder cap 15 and connects to the mounting baffle 21. The adjusting rod 24 is also threadedly connected to one set of guide rods 22. This structure allows the adjusting rod 24 to effectively drive the mounting baffle 21 and the pressure relief baffle 23, improving the working efficiency of the adjusting component.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When using the leak-proof cap of this gas cylinder, first tighten the cap 15 onto the cylinder valve 13 by rotating the lug 102. The first sealing gasket 14 and the second sealing gasket 16 ensure a good sealing effect to prevent gas leakage. When the pressure inside the gas cylinder is normal, the pressure relief baffle 23 is in the closed pressure relief port 101 state under the action of the elastic connection. If the pressure inside the gas cylinder rises abnormally, the pressure will push the pressure relief baffle 23 to open it to a certain extent, and the gas will be released through the pressure relief port 101, thereby reducing the pressure inside the cylinder and ensuring safety. The user can change the position of the baffle 21 by rotating the adjusting rod 24 according to the actual situation, thereby controlling the degree of pressure relief. In a dimly lit environment, the reflective sticker 17 can serve as a warning to help the user quickly find the location of the gas cylinder, while the label sticker 18 in the label slot 104 provides relevant information about the gas cylinder, making it easy for the user to understand the specific situation of the gas cylinder.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
