Description
BACKGROUND OF THE
Among the systems for the safety of ships, the gas sampling system is an essential system for oil tankers, gas lines and chemical wastes, and vessels of the above type that are recently dried must compulsorily adopt a gas sampling system.
This gas sampling system measures the concentration of explosive gas or oxygen in the tank where the flammable liquid is stored and keeps the concentration of explosive gas or oxygen in the tank below a certain level to prevent the risk of explosion.
Therefore, the crews measure the explosive gas and oxygen concentration in the tank from time to time through the gas sampling device.
After the connection tube is connected to the valve communicating with the tank of the ship, the gas collector positioned inside the connection tube is lowered and positioned inside the tank, and the gas collector is connected to the connection hose and descends together with the connection hose .
Then, when the descending of the gas collector is completed, when the gas is sucked through the gas measuring instrument connected to the connecting hose, the gas is sucked through the gas collector, and the gas is supplied to the connecting hose to be finally supplied to the gas collector, The concentration of gas or oxygen is measured.
But. In the conventional gas sampling device, a wide hole is formed inside the connection tube so that the connection hose for raising and lowering the gas collector can be easily transported. Due to such a wide hole, a gap between the connection tube and the connection hose (Hydrogen sulfide, benzene, flammable gas, etc.) remaining in the tank is discharged through the gap between the connecting tube and the connecting hose in the process of measuring the gas concentration. Therefore, the explosive gas and oxygen concentration in the tank are measured The measurer is easily exposed to noxious gas, causing damage to the lungs of the measurer or causing diseases such as cancer in the long term.
SUMMARY OF THE INVENTION The present invention has been proposed in order to solve all of the above problems, and an object of the present invention is to provide a hose which is capable of discharging harmful gas contained in a tank to the outside through a cover and a connecting hose penetrating the inside of the cover, A gas sensor is provided for preventing the sensor from being exposed to the harmful gas during the measurement of the explosive gas or oxygen concentration in the tank to prevent the sensor from being diseased by the harmful gas. And a gas sampling device.
In order to accomplish the above object, the present invention provides an airtight gas sampling device for a marine vessel, which is connected to a valve communicating with a tank inside the vessel, one end of which is exposed on a deck of a ship, A gas collector positioned inside the connection tube and having an inlet through which gas is introduced at one side thereof and an outlet through which the introduced gas is discharged at an upper portion thereof and a gas collector connected to the other end of the connection tube, A cover which is connected to the outlet of the gas collector through one end of the cover and the other end of the connection tube and whose other end is connected to the gas meter, A hose, and an on-off valve formed on the connecting hose to determine opening and closing of the connecting hose, A marine gas sampling device comprising:
And a closed nozzle which is connected to the upper portion of the cover to stably shut off the discharge of the gas contained in the tank between the inside of the cover and the connecting hose.
The closed nozzle includes a first female screw thread formed on the inside of the upper portion of the cover, a first male screw thread engaged with the first female thread on a lower outer circumferential surface, A gas tight packing in which an annular step is formed in an inner portion thereof, a gas tight packing which penetrates the inner portion to have a predetermined elasticity, is positioned inside the both screws, and the lower portion is in contact with the step of the both screws, And a nozzle cap having a tapered tightening portion that is sharpened as the upper portion of the inner cap is extended to the upper portion,
When the user tightens the nozzle cap to the both screws, the nozzle cap gradually descends. At this time, the upper portion of the hermetic packing is pressed and contracted in the throttling portion of the nozzle cap, and the inner surface of the hermetic packing passes through the hermetic packing. The outer circumferential surface of the connecting hose is closely contacted to maintain airtightness,
At the same time, the airtight packing is pressed downward on the descending nozzle cap, so that the lower part of the airtight packing and the step of the both screws are firmly brought into close contact with each other so that the airtightness is maintained to stably prevent the gas from being discharged between the cover and the connecting hose .
Further, a pressure body is formed on the hermetic packing, and the upper portion is further divided into a plurality of pieces at equiangular intervals,
When the nozzle cap is lowered by the screws, the upper portion of the pressure body is pressed to guide the upper portion of the hermetic packing to shrink, and the hermetic packing contacts the rotating nozzle cap, So that the hermetic packing is prevented from being deformed or damaged so as to enhance the structural stability of the device.
The cover further includes a ring packing formed between the cover and both screws to induce stable airtightness of the cover and both screws, thereby stably shielding gas from being discharged between the cover and both screws.
In addition, a knurling is formed on the outer circumferential surface of the nozzle cap so that the user can easily fasten the nozzle cap.
As described above, according to the gas sampling apparatus for marine vessels having airtightness according to the present invention, the noxious gas contained in the tank is discharged to the outside through the cover and the connecting hose passing through the inside of the cover, It is possible to stably prevent the measurer from suffering from the disease due to the harmful gas because the measurer does not be exposed to the harmful gas during the measurement of the explosive gas or oxygen concentration in the tank.
