Description
Technical field
The utility model belongs to compressed natural gas storing technology field, is specifically related to a kind of station with the drainage device of gas storage bottle type container group.
Background technique
Stand with the container storing compressed natural gas in gas storage bottle type container Zu Shi gas station, owing to containing impurity and water in rock gas, need to configure drainage device in station gas storage bottle type container group.Current drainage device is all arranged in the operation storehouse at rear portion, and drainage device is directly connected by end plug, there is the problem that assembling difficulty is large, the cycle is long.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model proposes a kind of station with the drainage device of gas storage bottle type container group.
The utility model adopts following technological scheme for completing above-mentioned purpose:
Stand with a drainage device for gas storage bottle type container group, described drainage device is arranged in the safety relief storehouse of station gas storage bottle type container group front end; Described drainage device includes inner drain pipe, outside drain pipe, threeway and elbow; Described threeway is connected to the front end of gas cylinder beyond the Great Wall, and is connected with gas cylinder by the inside drain pipe being positioned at gas cylinder; Described elbow is the reducing bend with internal and external screw thread; Described elbow is communicated with described threeway by outside thread; One end and the described inside drain pipe of described elbow are welded to connect; The outside drain pipe described in the other end connection of described elbow; Described outside drain pipe is connected with described inside drain pipe by elbow, threeway, integrant drainage device; Described threeway is also connected with the safety relief device in order to safety relief.
The other end of described elbow by being connected with described outside drain pipe silk II, and arranges blowdown valve between described elbow and outside drain pipe.
Described safety relief device includes safety valve and ball valve; Described ball valve is by being connected with described threeway to silk I, and described safety valve is connected on described ball valve.
A kind of station that the utility model proposes uses the drainage device of gas storage bottle type container group, drainage device is placed on safety relief storehouse, avoid drainage device be placed on operation storehouse time, owing to repeatedly filling the impact that gas causes inner drain pipe, greatly improve life-span and the safe application performance of inner drain pipe; Reduce the difficulty of the drainage device assembling of station gas storage bottle type container group, improve efficiency of assembling; Elbow and inner drain pipe are welded to connect, and are connected, greatly improve sealability, also improve the intensity of connection by the welding of stainless steel material of the same race.
