Description

Technical Field

[0001] The utility model specifically relates to the technical field of pressure vessels, and specifically relates to an explosion-proof pressure vessel with an adjustment structure. Background Technique

[0002] A pressure vessel is a sealed container that can withstand pressure. Pressure vessels have extremely wide applications and play an important role and function in many departments such as industry, civil use, military, and many fields of scientific research. When the internal pressure of some pressure vessels filled with gas exceeds the maximum pressure that the container bottle can withstand, the container will deform and crack, causing gas leakage, resulting in the scrapping of the container and a great waste of resources.

[0003] Chinese Utility Model Publication No. CN 218153620 U discloses an explosion-proof pressure vessel, which includes a container body. One side of the container body is communicated with a pressure relief component, and two detection components are correspondingly installed on the other side of the container body, and the detection components are arranged in a supporting manner with the pressure relief component;

[0004] For the above-mentioned explosion-proof pressure vessel, the detection rod directly contacts the pressure sensor and applies pressure to the pressure sensor to start the first solenoid valve. The gas is transported to the transfer cavity through the first pipeline, and then the first solenoid valve is closed, and at the same time the second solenoid valve is opened, so that the gas in the transfer cavity is quickly transferred to the pressure relief tank to achieve pressure relief. However, such a pressure relief method is to relieve pressure outward and has only one layer of protection effect, and the protection effect is poor. Therefore, we provide an explosion-proof pressure vessel with an adjustment structure. The inner load-bearing cylinder on the inner side plays a bearing role. When the inner pressure increases, the bursting disc on one side of the inner load-bearing cylinder will break, and the released pressure or other substances are still inside the explosion-proof outer cylinder and will not leak out, playing a better protection effect. Secondly, the explosion-proof outer cylinder on the outside also plays a layer of protection role, effectively making up for the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an explosion-proof pressure vessel with an adjustment structure to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An explosion-proof pressure vessel with an adjustment structure includes an explosion-proof outer cylinder; an inner fixing frame is welded inside the explosion-proof outer cylinder, and an inner load-bearing cylinder is fixed to the inner fixing frame by bolts, and a bursting disc is welded on one side of the inner load-bearing cylinder in a matching manner. Secondly, an inner cover is arranged on the side of the inner load-bearing cylinder away from the bursting disc, and the inner cover locks the inner load-bearing cylinder through an inner pressure lock; outer covers are arranged at both ends of the explosion-proof outer cylinder.

[0008] As a further technical solution of the present utility model, an input pipe and an output pipe are respectively arranged above and below the inner bearing cylinder, and one-way valves are connected in cooperation on both the input pipe and the output pipe.

[0009] As a further technical solution of the present utility model, a pressure gauge is connected in cooperation on the inner bearing cylinder, and the pressure gauge extends to the outside of the explosion-proof outer cylinder.

[0010] As a further technical solution of the present utility model, a turning arm is movably connected to the outer cover through a rotating shaft, the turning arm is movably connected to the support arm through a rotating shaft, and the other end of the support arm is welded to the explosion-proof outer cylinder.

[0011] As a further technical solution of the present utility model, locking rings are connected in cooperation on both sides of the explosion-proof outer cylinder through annular bearings. The locking rings are provided with slots for facilitating the snap connection of the outer cover, and connecting plates are welded on the locking rings.

[0012] As a further technical solution of the present utility model, the connecting plate is movably connected to the push rod of the opening and closing air cylinder through a rotating shaft. The opening and closing air cylinder is movably connected to the outer support plate through a rotating shaft, and the outer support plate is welded to the outside of the explosion-proof outer cylinder; legs are welded to the bottom of the explosion-proof outer cylinder.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the inner bearing cylinder bears gas or liquid. When the inner pressure is too high, the more fragile bursting disc will be broken through, so that the gas or liquid pressure is discharged to the inside of the explosion-proof outer cylinder, preventing it from leaking to the outside. The inner cover is connected to the inner bearing cylinder by an internal pressure lock, which is convenient for cleaning the inside of the inner bearing cylinder. The two outer covers play a role in closing both ends of the explosion-proof outer cylinder;

[0015] 2. In the present utility model, the input pipe and the output pipe are convenient for inputting or outputting liquid or gas into the inner bearing cylinder. The one-way valve plays a role of one-way opening and closing, and the pressure gauge is convenient for the staff to observe the inner pressure in real time;

[0016] 3. In the present utility model, the outer cover is driven by the turning arm to rotate and buckle on the explosion-proof outer cylinder. Under the action of the opening and closing air cylinder movably connecting the outer support plate and the push rod of the opening and closing air cylinder movably connecting the connecting plate through a rotating shaft, the locking ring can be rotated to press and lock the outer cover. The legs are convenient for the explosion-proof outer cylinder to play a supporting role. Description of the Drawings
