[0002] A pressure vessel is a closed container that can withstand pressure. In the chemical and petrochemical fields, pressure vessels are mainly used in heat transfer, mass transfer, reaction and other process, as well as storage and transportation of pressurized gas or liquefied gas. They are also widely used in other industrial and civil fields.

[0003] Most of the existing pressure vessels are single-layer tanks. However, when storing gas, single-layer pressure vessels are prone to poor airtightness, which can easily lead to leakage of stored gas. Moreover, for pressure vessels that need to be buried underground, single-layer tanks are easily affected by pressure, causing the tank wall to dent and deform, and single-layer pressure vessels have poor impact resistance. Therefore, a new type of double-layer gas storage pressure vessel is urgently needed to solve the above problems. Utility Model Content

[0006] In order to successfully achieve the purpose of preventing the double-layer gas storage pressure vessel from being easily dented and deformed after being buried underground and preventing gas leakage, the double-layer pressure vessel mounting assembly includes a fixing ring fixedly connected to the outer wall of the air inlet pipe, the fixing ring is bolted fixedly connected to the outer container wall, the side wall of the outer container wall is fixedly connected to a mounting ring, and the mounting ring is threadedly connected to mounting bolts.

[0007] In order to successfully achieve the goal of improving the anti-collision performance of the gas storage pressure vessel, the pressure vessel anti-collision assembly includes a shock-absorbing support plate fixedly connected to the side wall of the outer container wall, the shock-absorbing support plate is connected to a shock-absorbing damper, the shock-absorbing support plate is connected to a shock-absorbing spring, and another group of shock-absorbing support plates is fixedly connected to an anti-collision plate.

[0008] Furthermore, the air inlet pipe is sealedly connected to the closing cover, and a fixing bolt is threadedly connected between the fixing ring and the outer container wall.

[0009] Furthermore, the air inlet pipe and the closing cover are symmetrically arranged at two ends of the pressure container tank.

[0010] Preferably, the fixing ring and the mounting ring are both arranged in a ring shape, and the anti-collision plate is arranged in an arc shape.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows:

[0012] 1. The double-layer pressure vessel installation assembly can be used to easily install the second layer of the container wall outside the existing single-layer pressure vessel, so that the double-layer gas storage pressure vessel is not easy to sag and deform after being buried underground and prevents gas leakage;
