Description

Technical Field

[0001] The utility model relates to the field of gas preparation, in particular to a gas storage device. Background Art

[0002] Existing gas preparation devices often use a large number of pressure tanks, each with a volume that must meet usage requirements. During use, these large pressure tanks take a long time to build up pressure, preventing the gas preparation device from immediately producing the desired finished gas. This requires a long preheating period to build up pressure, impacting the user experience. Utility Model Content

[0003] In order to solve the shortcomings of the existing technology, the utility model provides a gas storage device, which is equipped with a first one-way valve and a second one-way valve with differentiated opening pressure differences. After the air pressure in the main tank meets the finished product air pressure requirement, the first one-way valve is opened and the auxiliary tank is inflated, which ensures that the air pressure in the main tank can be quickly increased to form usable finished product gas, shortening the pressure accumulation time, and can also use the auxiliary tank to store gas and replenish gas to the main tank, ensuring that the amount of finished product gas meets the use requirements.

[0004] The utility model is achieved in the following way: a gas storage device includes a gas storage tank group, the gas storage tank group includes a main tank and a sub-tank connected to the main tank, the main tank is provided with an air inlet and an air outlet, the main tank and the sub-tank are connected by a connecting pipe group, the connecting pipe group includes a first pipe with a first one-way valve and a second pipe with a second one-way valve, the first pipe and the second pipe are connected in parallel between the main tank and the sub-tank, the gas in the main tank is diverted to the sub-tank through the first pipe, and the gas in the sub-tank flows back to the main tank through the second pipe, and the pressure difference required to open the first one-way valve is greater than the pressure difference required to open the second one-way valve. A first one-way valve and a second one-way valve with differentiated opening pressure differences are set. After the air pressure in the main tank meets the finished product pressure requirement, the first one-way valve is opened and the auxiliary tank is inflated. By supplying gas to the main tank separately, the air pressure in the main tank is ensured to increase quickly, and the finished gas with the air pressure meeting the use requirements is formed, shortening the pressure accumulation time. The auxiliary tank can also be used to store the gas overflowed from the main tank, and replenish gas when the pressure in the main tank drops, to ensure that the amount of finished gas meets the use requirements.

[0005] Preferably, the main tank is cylindrical, and the inner wall diameter of the main tank is less than 150 mm, which is convenient for processing using tubular raw materials and reduces the volume by reducing the inner wall diameter, thereby facilitating the rapid accumulation of air pressure and forming finished gas that meets the air pressure requirements.

[0006] Preferably, the auxiliary tank is cylindrical, and the inner wall diameter of the main tank is less than 150 mm, which is convenient for processing using tubular raw materials and also reduces the volume by reducing the inner wall diameter, making it convenient for assembly and use with the main tank.

[0007] Preferably, the auxiliary tank and the main tank are fixedly connected by a connecting plate to ensure that the relative position between the auxiliary tank and the main tank is fixed, thereby protecting the connecting pipe group.

[0008] Preferably, the auxiliary tank is arranged at the periphery of the main tank to reduce the length of the first and second pipes. The auxiliary tank is arranged adjacent to the main tank, effectively shortening the length of the connecting pipe group and effectively utilizing the space around the main tank to provide space for the installation of more auxiliary tanks.

[0009] Preferably, there are at least two auxiliary tanks, which are connected to the main tank through a connecting pipe group respectively. Each auxiliary tank is independently connected to the main tank. The auxiliary tanks can be increased or decreased according to the required capacity, and can also be pre-produced and quickly assembled to improve production efficiency.

[0010] Preferably, the first one-way valve corresponding to each sub-tank has a differentiated pressure difference required for opening. By setting different pressure differences required for opening, each sub-tank can be used at different times, ensuring that each sub-tank can quickly accumulate air pressure and ensure that the finished gas can be effectively utilized.

[0011] Preferably, a capacity expansion tank is provided on the auxiliary tank, and the capacity expansion tank and the auxiliary tank are connected by an air pipe. The capacity expansion tank is provided to increase the volume of the auxiliary tank, thereby improving the user experience.

[0012] Preferably, there are at least two expansion tanks and they are connected in series to the corresponding auxiliary tanks through air pipes. The expansion tanks are pre-produced and can be connected to the auxiliary tanks through quick assembly, which improves production efficiency and does not require space around the main tank, providing space for the installation of the auxiliary tanks.

[0013] Preferably, the auxiliary tank and the capacity expansion tank are fixedly connected by a connecting plate to ensure that the two are firmly connected.

[0014] Preferably, the expansion tank is cylindrical, and the inner wall diameter of the main tank is less than 150 mm, which is convenient for processing using tubular raw materials and reduces the volume by reducing the inner wall diameter, thereby improving the capacity adjustment accuracy of the gas storage device.

[0015] Preferably, a bracket is provided on the surface of the gas storage tank group, and the gas storage tank group is installed on a preset work position through the bracket to ensure that the gas storage tank group is reliably positioned.

[0016] The beneficial effects of the present invention are as follows: a first one-way valve and a second one-way valve with differentiated opening pressure differences are provided. When the air pressure in the main tank meets the finished product pressure requirement, the first one-way valve is opened and the auxiliary tank is inflated. This ensures that the air pressure in the main tank can be quickly increased by supplying gas to the main tank alone, and forms finished gas with an air pressure that meets the use requirements, shortening the pressure accumulation time. The auxiliary tank can also be used to store gas overflowing from the main tank, and replenish gas when the pressure in the main tank drops, ensuring that the amount of finished gas meets the use requirements.

[0023] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0024] like Figure 1 The gas storage device shown is composed of a gas tank group, which includes a main tank 1 and a sub-tank 2 connected to the main tank 1. The main tank 1 is provided with an air inlet 3 and an air outlet 4. The main tank 1 and the sub-tank 2 are connected by a connecting pipe group, and the connecting pipe group includes a first pipe 5 with a first one-way valve 6 and a second pipe 7 with a second one-way valve 10. The first pipe 5 and the second pipe 7 are connected in parallel between the main tank 1 and the sub-tank 2. The gas in the main tank 1 is diverted to the sub-tank 2 through the first pipe 5, and the gas in the sub-tank 2 flows back to the main tank 1 through the second pipe 7. The pressure difference required to open the first one-way valve 6 is greater than the pressure difference required to open the second one-way valve 10. A first one-way valve 6 and a second one-way valve 10 with differentiated opening pressure differences are set. After the air pressure in the main tank 1 meets the finished product air pressure requirement, the first one-way valve 6 is opened and the auxiliary tank 2 is inflated. By delivering gas to the main tank 1 alone, it is ensured that the air pressure in the main tank 1 can be quickly increased, and the finished gas with an air pressure that meets the use requirements is formed, shortening the pressure accumulation time. The auxiliary tank 2 can also be used to store the gas overflowed from the main tank 1, and replenish gas when the pressure in the main tank 1 drops, to ensure that the amount of finished gas meets the use requirements.

[0025] In actual operation, the gas in the main tank 1 can be transferred to the auxiliary tank 2 through the first one-way valve 6, and the gas in the auxiliary tank 2 cannot flow back to the main tank 1 through the first one-way valve 6. The gas in the auxiliary tank 2 can flow back to the main tank 1 through the second one-way valve 10, and the gas in the main tank 1 cannot be transferred to the auxiliary tank 2 through the second one-way valve 10. Both the first one-way valve 6 and the second one-way valve 10 are opened by the pressure difference between the two sides, thereby ensuring that the airflow is delivered in the predetermined direction.

[0026] In actual operation, the air pressure difference required to open the first one-way valve 6 is greater than the air pressure of the finished gas, ensuring that when the air pressure in the main tank 1 is greater than the air pressure of the finished gas, gas is supplied to the auxiliary tank 2 through the first one-way valve 6, and the air pressure difference required to open the second one-way valve 10 approaches zero, ensuring that the auxiliary tank 2 can supply gas to the main tank 1 when the air pressure in the main tank 1 is lower than the air pressure in the auxiliary tank 2.

[0027] During inflation, the finished gas generated by the gas preparation device will be transported to the main tank 1 through the air inlet 3. Since the air pressure in the main tank 1 is relatively low, the first one-way valve 6 cannot be opened, and the second one-way valve 10 cannot transport gas to the sub-tank 2, so that the gas can only be in the main tank 1 and the air pressure is quickly increased to form a finished gas with an air pressure that meets the use requirements, thereby improving the user experience by shortening the preheating time of the accumulated air pressure; when the gas preparation device is large enough to produce finished gas, the air pressure in the main tank 1 is greater than the finished gas pressure and triggers the first one-way valve 6 to open, so that the excess gas in the main tank 1 can be transported to the sub-tank 2. Since the air pressure in the main tank 1 is greater than that in the sub-tank 2, the second one-way valve 10 cannot transport the gas in the sub-tank 2 to the main tank 1.

[0028] During exhaust, the finished gas in the main tank 1 is discharged through the outlet 4 for use. When the air pressure in the main tank 1 drops and is lower than that in the sub-tank 2, the second one-way valve 10 opens, and the sub-tank 2 replenishes the finished gas to the main tank 1. When the air pressure in the main tank 1 is lower than that of the finished gas, the second one-way valve 10 closes, ensuring that the gas from the air inlet 3 is retained in the main tank 1, effectively maintaining the air pressure in the main tank 1.

[0029] In actual operation, there are at least two sub-tanks 2, each of which is connected to the main tank 1 via a connecting pipe group. The first one-way valve 6 corresponding to each sub-tank 2 has a different required pressure difference for opening, and the required pressure difference for opening the first one-way valve 6 is greater than the required pressure of the finished gas. Specifically, the required pressure difference for opening each first one-way valve 6 is increased by an equal value, so that each first one-way valve 6 will only open when the corresponding required pressure difference for opening is met. This ensures that the sub-tanks 2 corresponding to each first one-way valve 6 are used at different times. As the air pressure in the main tank 1 gradually rises, they are opened one by one, preventing the sub-tanks 2 from being opened synchronously and prolonging the time it takes to accumulate air pressure. This ensures that each sub-tank 2 can quickly accumulate air pressure, and the number of sub-tanks 2 activated will be automatically adjusted according to the amount of finished gas. In addition, the second one-way valve 10 of each sub-tank 2 can also be set with a stepped required pressure difference for opening, so that the air pressure in each sub-tank 2 is used one by one, which should also be considered a specific embodiment of the present invention.

[0030] In actual operation, the auxiliary tank 2 is arranged on the periphery of the main tank 1 (such as Figure 2 and 3 As shown in the figure, the length of the first pipe 5 and the second pipe 7 is shortened. Since the peripheral space of the auxiliary tank 2 is limited, a capacity expansion tank 8 is provided on the auxiliary tank 2 to increase the volume of each auxiliary tank 2. The capacity expansion tank 8 and the auxiliary tank 2 are connected by air pipes. There are at least two capacity expansion tanks 8 and they are connected to the corresponding auxiliary tanks 2 in series or in parallel (as shown in the figure). Figure 4 and 5 As shown), the expansion tank 8 is arranged on the side of the auxiliary tank 2 facing away from the main tank 1, effectively utilizing the outer space of the auxiliary tank 2.

[0031] In actual operation, the main tank 1, the auxiliary tank 2 and the expansion tank 8 are all cylindrical. The inner wall diameter of the main tank 1 is less than 150 mm, which is convenient for processing using general tubular raw materials, effectively reducing costs, and is also convenient for assembly and use according to the required volume.

[0032] In actual operation, the auxiliary tank 2 and the main tank 1, and the auxiliary tank 2 and the capacity expansion tank 8 are fixedly connected by connecting plates. A bracket 9 is provided on the surface of the gas storage tank group, and the gas storage tank group is installed on a preset work station through the bracket 9.
