Claims

[Scope of claim for utility model registration] 1. Inlet port 2 for gas stored in gas cylinder 1;
The filling valve chamber 3, the extracting valve chamber 4, and the outlet 5 are connected to one
They are connected in series on the center line 6 of the book, and the filling valve body 7 is inserted into the filling valve chamber 3 and the taking-out valve body 8 is inserted into the taking-out valve chamber 4. A valve body stopper 9 is provided between the valve chamber 4, and the filling body 7 and the valve body 8 for taking out are connected to each valve closing spring 10, 11.
Press the valve body against the stopper 9 side with the
13 are brought into contact with each other so that each vent passage 14 running in the direction of the center line 6 is formed in each valve body 7, 8.
. The closing pressure receiving surface 17 of the filling valve body 7 is pressurized to push the filling valve body 7 away from the take-out valve body 8 against the valve closing spring 10 to open the valve, and the filling gas 16 is further opened. It is press-fitted into the gas cylinder 1 from the inlet 2 through the valve gap 18, the filling valve chamber 3, and the air passage 14 of the filling valve body 7, and
When the gas 19 contained in the gas cylinder 1 is taken out of the cylinder, the stored gas 19 passes through the inlet 2, the filling valve chamber 3, the air passage 14 of the filling valve body 7, and the taking-out valve chamber 4. The valve opening pressure receiving surface 20 of the valve body 8 is pressurized, and the takeout valve body 8 is closed by the valve closing spring 11.
The valve is opened by pushing it away from the filling valve body 7 against the
When the stored gas 19 further flows out from the outlet 5 through the valve opening gap 21 and the vent passage 15 of the take-out valve body 8, and the internal pressure of the gas cylinder 1 has decreased to the residual pressure value, the valve is closed. The spring 11 overcomes the internal pressure of the cylinder and brings the take-out valve element 8 into contact with the filling valve element 7 to close the valve, thereby blocking the outflow of the stored gas 19 and preventing the internal pressure of the cylinder from falling below the residual pressure value. In the configured residual pressure valve for a gas cylinder, one of the valve bodies 22 of the take-out valve body 8 and the filling valve body 7 is formed with a ventilation passage 15 passing through the central part of the valve body. Female valve surface 13 on the hole circumferential surface
A sealing ring 23 is used to seal between the outer circumferential surface of the valve body and the circumferential surface of the valve chamber, and the other valve body 24 protrudes from the center of one end surface of the valve body. The valve closing contact surface between the male valve surface 12 and the female valve surface 13 is sealed with a valve closing seal 25, and one end surface of the valve body is opened from the center of the other end surface of the valve body. A residual gas cylinder for a gas cylinder characterized in that a ventilation passage 14 is formed to extend through a portion near the outer periphery, and the outer circumferential surface of the valve body and the circumferential surface of the valve chamber are brought into frictional contact via a frictional contact member 26. Pressure valve. 2. The female valve surface 13 consists of a tapered cylindrical surface 27 and a right cylindrical surface 28 continuous to the narrow diameter end of the tapered cylindrical surface 27,
