[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 - Figure 3The utility model provides an embodiment: a moisture-proof and rust-proof double-layer liquefied petroleum gas cylinder, comprising an outer shell 1, a bottle body 2 is fixedly connected to the bottom inner wall of the outer shell 1, so that the outer shell 1 can provide protection for the bottle body 2, a connecting pipe 3 is fixedly connected to the top of the bottle body 2, so that the liquefied gas entering the connecting pipe 3 can enter the inside of the bottle body 2, an air intake pipe 4 is fixedly connected to the middle part of the right side of the connecting pipe 3, so that the gas entering the inside of the air intake pipe 4 can enter the inside of the connecting pipe 3 through the inside of the air intake pipe 4, a fixing ring 5 is fixedly connected to the inside of the air intake pipe 4, and a fixing column 6 is fixedly connected to the top and bottom of the left side of the fixing ring 5, so that the fixing ring 5 can provide support for the fixing column 6, and a spring 7 is sleeved on the outside of the fixing column 6.
[0025] The top left side of the fixed column 6 is fixedly connected to a limiting plate 8, and the outside of the fixed column 6 is slidably connected to a pressure plate 9, which can make the pressure plate 9 slide more stably. One end of the spring 7 is fixedly connected to the left side of the pressure plate 9, and the other end of the spring 7 is fixedly connected to the right side of the limiting plate 8, so that the pressure plate 9 will compress the spring 7 when it moves, and the limiting plate 8 can prevent the pressure plate 9 from falling off the outside of the fixed column 6 when it slides on the outside of the fixed column 6. The right side of the pressure plate 9 contacts the left side of the fixed ring 5, and a through hole is opened in the middle of the fixed ring 5. The top of the outer shell 1 is fixedly connected to a lifting assembly, and the lifting assembly includes a lifting plate 10. The bottom of the lifting plate 10 is fixedly connected to the top of the outer shell 1, and lifting holes 11 are opened on the left and right sides of the lifting plate 10, so that the staff can move the device by pulling the lifting holes 11.
[0026] like Figure 1 and Figure 4 As shown: an insulating layer 13 is arranged on the outside of the bottle body 2, an anti-corrosion coating 12 is arranged on the outside of the outer shell 1, and the insulating layer 13 is made of glass fiber. Glass fiber is an excellent insulating material with good thermal insulation performance. Using glass fiber as the insulating layer 13 can effectively isolate the heat conduction between the external high temperature environment and the internal liquefied petroleum gas, prevent the influence of external heat on the petroleum gas, and ensure that the internal temperature is relatively stable. The glass fiber insulating layer 13 can reduce the loss of the internal temperature of the liquefied petroleum gas cylinder and improve the thermal insulation effect of the cylinder. This is particularly important for the situation where the liquefied petroleum gas needs to be stored or transported for a long time, and can ensure that the petroleum gas maintains a suitable temperature when in use.
[0027] The material of the anti-corrosion coating 12 is an epoxy resin coating. The epoxy resin coating has excellent corrosion resistance and can effectively resist the corrosion of chemicals, moisture and oxygen in the external environment to the cylinder. By using the epoxy resin coating, a solid protective layer can be provided to delay the corrosion of the cylinder surface, thereby extending the service life of the cylinder. The epoxy resin coating has excellent weather resistance and can resist the influence of external environments such as ultraviolet rays, high temperature, low temperature, and humidity. Therefore, the outer shell 1 of the liquefied petroleum gas cylinder is provided with an epoxy resin coating to maintain stable performance and appearance under different climatic conditions, and the other side of the thermal insulation layer 13 is in contact with the inner wall of the outer shell 1.
[0028] Compared with some existing technologies, the above content can prevent the problem of the injected LPG escaping from occurring during the period when the valve is turned to seal the inside of the gas cylinder after the LPG is injected into the gas cylinder during use, and can effectively prevent the external environment from corroding the device, and can effectively reduce heat conduction and air convection, thereby improving the moisture-proof and rust-proof properties of the cylinder.
[0029] Working principle: first, connect liquefied gas to the inside of the air intake pipe 4, so that the liquefied gas will impact the pressure plate 9, which will cause the pressure plate 9 to slide on the outside of the fixed column 6, and then the pressure plate 9 will compress the spring 7, and then the liquefied gas entering the air intake pipe 4 can enter the inside of the connecting pipe 3 through the inside of the air intake pipe 4, and then the liquefied gas in the connecting pipe 3 will enter the inside of the bottle body 2 through the inside of the connecting pipe 3. When the liquefied gas entering the bottle body 2 reaches a certain pressure, it will press the pressure plate 9, causing the pressure plate 9 to slide on the outside of the fixed column 6 toward the direction of the fixing ring 5, so that the inside of the air intake pipe 4 can be sealed to prevent the liquefied gas entering the bottle body 2 from leaking, and it can pass The anti-corrosion coating 12 and the heat-insulating layer 13 are set, so that the epoxy resin coating can provide a solid protective layer, delay the corrosion of the cylinder surface, and thus extend the service life of the cylinder. Because the epoxy resin coating has excellent corrosion resistance and adhesion, it can effectively prevent the steel surface from getting damp and rusting. It also has the characteristics of good weather resistance and strong wear resistance. Because glass fiber is a commonly used insulation material with good heat insulation and corrosion resistance, it can effectively reduce heat conduction and air convection, thereby improving the moisture and rust resistance of the cylinder. The glass fiber insulation layer 13 can reduce the loss of temperature inside the liquefied petroleum gas cylinder and improve the insulation effect of the cylinder. This is particularly important for situations where liquefied petroleum gas needs to be stored or transported for a long time, and can ensure that the petroleum gas maintains a suitable temperature when in use.
