The application number 96191260.X that Enron LNG Dev. Corp of the U.S. applies in China patent discloses a kind of ship based system for compressed natural gas transport, it is provided with pressurized gas reservoir vessel aboard ship, each pressurized gas reservoir vessel comprises 3 ~ 30 gas cylinders, gas cylinder is installed belowdecks with Vertical direction, cabin hatch cover covers, in case enter at seawater.By gas cylinder and pipeline sealing belowdecks, its shortcoming is: 1. natural gas leaking in cabin, easily cause the blast of CNG cargo ship; 2. pipeline is arranged in cabin, is not easy inspection and maintenance.
China application application number be 200680023284.X patent discloses a kind of vessel for transport of compressed natural gas, be positioned at storage tank on hull except upper end all in airtight space, the upper end of these storage tanks is equipped with a limit and encloses, the cover joint that extends is set above deck, enclosed directly to be suspended on by limit by storage tank and extend on cover joint, all supporting pipelines are all arranged on outside cabin.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of end plug assembly for CNG cargo ship air cylinder, valve seat stretches out out of my cabin by setting out storekeeper by it, isolation for gas cylinder and pipeline arranges and provides another kind of mode, and reduces the risk that rock gas leaks to cylinder storage cabin.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of end plug assembly for CNG cargo ship air cylinder, comprise and to be tightly connected with the upper whorl of bottleneck of bottle and to be provided with the end plug body passing in and out vent hole and drain pipe, also comprise and to be communicated with described end plug body and to pass going out storekeeper and being arranged on out the valve seat on storekeeper of hatchcover.
Described drain pipe is positioned in the turnover vent hole of end plug body; Described go out storekeeper be coaxial setting double wall pipe, be communicated with drain pipe with the turnover vent hole on end plug body respectively, valve seat is provided with sewage draining valve and air valve door.
The effect going out storekeeper is whole bottle is arranged in airtight cabin on the one hand, prevents severe maritime environment to its corrosion or is exposed to the sun; Go out between storekeeper and hatchcover on the other hand and easily seal.
Supporting disk is being set higher than going out on storekeeper outer wall of hatchcover, supporting disk is also being provided with the positioning hole of alignment sensor cover; Described sensor sleeve stretches in bottle through supporting disk and end plug body.May need in bottle to arrange various kinds of sensors, as temperature transducer, humidity transducer, the effect of this supporting disk: 1. for locating with the sealing of hatchcover, 2. can alignment sensor cover, 3. between the gas cylinder group that two row air cylinders are corresponding for support bridge type bearing, the pipe clamp of spacing handling air pipe is set above bridge supports, thus pipeline is erected at above hatchcover.
In technique scheme, by going out storekeeper, whole pipeline being arranged on out of my cabin, realizing the isolation of pipeline and bottle, can available protecting bottle, natural gas leaking can be prevented again accidents caused.
The beneficial effect adopting technique scheme to produce is: (1) the utility model only needs the end plug of routine to improve, the isolation that can realize bottle and pipe-line system is arranged, be conducive to hull safe spacing on the one hand, improve the safety coefficient of cargo ship on the other hand; (2) in further improved plan, go out the supporting disk that storekeeper is arranged and realize top seal, can form airtight cabin environment on the one hand, make the environment keeping safety in cabin, preventing solving severe maritime environment causes erosion to bottle on the other hand; (3) can also support sensor by end plug body and supporting disk, the one end such as temperature transducer are stretched in bottle hermetically, the other end is arranged on touring passage both sides above hatchcover, is convenient to observe.
