Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.
Example (b):
referring to fig. 1 and 2, the storage tank device with rupture discs comprises a tank body 1, wherein a feeding pipe 2 and a discharging pipe 3 which are communicated with an inner cavity of the tank body 1 are arranged on the side wall of the tank body 1; a connecting pipe 4 communicated with the inner cavity of the tank body 1 is arranged on the side wall of the tank body 1 close to the top; a safety valve 5 is arranged on the connecting pipe 4, and a blasting diaphragm 6 for blocking the fluid flow is arranged on the connecting pipe 4 between the safety valve 5 and the tank body 1.
In the embodiment, the tank body 1 is used for storing liquefied natural gas, the liquefied natural gas is input into the tank body 1 through the feed pipe 2, and is output through the discharge pipe 3 when the liquefied natural gas needs to be transferred; the liquid level of the liquefied natural gas is positioned below the inlet of the connecting pipe 4; when the gas pressure above the liquid level in the tank body 1 is too large, the blasting diaphragm 6 is broken by high pressure, then the safety valve 5 is opened by the gas pressure, and the gas in the tank body 1 is discharged to the emptying header pipe or the collecting and processing device for centralized disposal by a 4-way connecting pipe at the rear end of the safety valve 5. This embodiment is through setting up blasting diaphragm 6 on connecting pipe 4 between the relief valve 5 and jar body 1, breaks the diaphragm and dashes to open relief valve 5 when jar body 1 atmospheric pressure is too big in proper order, when guaranteeing that jar body 1 internal gas pressure can not transfinite, has still avoided directly adopting relief valve 5 to produce the problem of oozing in easily through connecting pipe 4 and jar body 1 when being connected.
The burst membrane 6 is generally made of aluminum film and can be integrally formed with the connecting tube 4 (welded or bonded in the inner cavity of the connecting tube 4). In this embodiment, two flanges 7 are provided coaxially and oppositely at positions where the burst disk 6 is attached to the connecting pipe 4, and the burst disk 6 is held between the two flanges 7.
