Problems solved by technology

[0003] In the prior art, the ventilation pressure of the mainstream C-type tank is usually set at 4 to 4.5 bar, so the corresponding LNG (density about 0.44t / m3) filling rate is usually about 90%, and the use efficiency of the C-type tank , there is still room for improvement, and the filling rate setting is single, and users cannot choose according to their own usage

Embodiment 1

[0053] like figure 1 Shown, the assembly comprises at least two first relief pressure release valve 21, all of the first pressure relief valve 21 is connected in parallel to the C-1 LPG tanks, and all the first pressure relief valve 21 different relief pressure value, said first pressure relief valve 21 for controlling the C-1 liquefied gas tank pressure is less than the design pressure of a C liquefied gas tanks.

[0054] According to an embodiment of the present invention, the pressure relief assembly by providing two or more than two, and a first relief pressure release valve 21 value ranging, for the purpose of changing the filling rate when higher when the filling rate, can be employed lower first pressure relief valve 21, when long term storage, that a higher relief pressure of the first pressure relief valve 21, the pressure relief valve 21 has a first parallel connections, such that each first pressure release do not affect each other during operation between the valve 21,...

Embodiment 2

[0066] like figure 2 Shown, the pressure relief assembly includes a first adjustable pressure relief valve 31, the first adjustable pressure relief valve 31 is connected to the liquefied gas tank 1 C, the first pressure relief valve 31 with an adjustable C for controlling the internal pressure liquefied gas tank 1 C is less than the design pressure of the liquefied gas tank 1.

Abstract

The invention provides a pressure control system with a C-shaped liquefied gas cabin, and relates to the technical field of oil and gas storage and transportation. The pressure control system comprises a pressure relief assembly, the pressure relief assembly is connected with the C-shaped liquefied gas cabin, the pressure relief assembly is used for controlling the pressure in the C-shaped liquefied gas cabin to be smaller than the designed pressure of the C-shaped liquefied gas cabin, and meanwhile, the pressure relief pressure value of the pressure relief assembly can be adjusted according to the working condition. Due to the fact that the filling rate of the C-shaped liquefied gas cabin is related to the pressure relief pressure, the pressure of the pressure relief assembly is adjustable, and therefore the filling rate of the C-shaped liquefied gas cabin can be adjusted according to the pressure relief pressure set by the pressure relief assembly, the filling rate and the suffocation time of the C-shaped liquefied gas cabin are changed by adjusting the pressure relief pressure, a user can select the proper pressure relief pressure according to own requirements, the practical flexibility of the C-shaped liquefied gas cabin is improved, and the experience feeling of the user is greatly improved.

Description

Technical field [0001] The present invention relates to the field of oil and gas storage and transportation, particularly to a C liquefied gas tank pressure control system. Background technique [0002] C liquefied gas storage tanks as a major natural gas storage tank pressure type, with the promotion of clean energy, are increasingly using scenario. C-tank volume and size is directly dependent on the needs of users at user demand, where the pressure is provided and a certain rate of filling cans, the size of C-shaped tank that is itself determined. [0003] In the prior art, air pressure in the main tank is generally C-disposed 4 ~ 4.5bar, thereby corresponding LNG (density of about 0.44t / m3) filling rate is usually about 90%, efficiency in the use of Type C tank , there is still room for improvement, and set a single rate of filling, the user can not choose according to their usage. Inventive content [0004] (A) of the present invention is to solve is: to enhance the fillin...
