The fourth air barrier (49) pushes the valve core (40) back. By using the air passed through the duct (35), the air chamber (41) is a type of air chamber for storage to accumulate enough air pressure. In order to push the valve core (40) backward. The valve is closed. Where the retention of pressure volume Will get a lot of pressure in time That is short or long It depends on how much the screw (11) at the air chamber (110) is adjusted for the opening of the air inlet if adjusting the screw (11) so that the air inlet coming from the air duct (35) is open. When the pressure accumulation in this chamber is wider, the back pressure operation is shortened. This causes the shutdown of this valve to push the valve core (40) back to work quickly after the weighing scale. Weigh the gas that can be loaded into the tank. As defined But if adjusting screw (11) so that the air inlet coming from the wind pipe (35) narrows the time of pressure build-up in this chamber. It will take Push back work will be long. This causes the shutdown of the valve to push the valve core (40) back, it will work slowly after the weighing. Weigh the gas that can be loaded into the tank. As set 1 4. Equipment for gas filling. According to claim 1, the loaded gas check valve (20) has the duty to check the weight of the gas loaded into the tank as determined by using the installation position as a weight measurement. It is a bar, cage, cylinder, threaded on the outer surface, with two bolts (44,45) screwed in to tighten the position at Needed on the weighing scale One end of the barrel cage bar For the inlet air coming from the second control valve assembly (23) through the air hose (12), there is a hose coupling (15), the other end is an internal air outlet with a check pin ( 21) It is a valve seal. Will be closed by the pressure of the spring (62) all the time, the wind does not. Able to flow through This closed valve cavity is conical in shape, the check needle (21) extends from the inside. To the outer end The tip of the check needle (21) inside is cone-shaped like the mouth. The valve at the apex of the conical shape is a check needle (21) extending to the outside of the cylinder body, where the end of the check pin (21) inside has a spring (62) pushing the valve. The air will only flow out when something pushes the check needle (21) into the check valve (20), causing the valve mouth to open. 5. Equipment for gas filling. According to claim 1, the second cylinder (2) has the characteristics of There are two functions. One is the movement of the piston in and out of the cylinder, the second acts as a gas shut-off valve. Will act to control the flow of Gas from the gas supply to the desired gas cylinder Both functions work simultaneously while the second cylinder (2) is in and out. The valve body also moves to open the valve as the core or stem of the cylinder is the same as the axis of the valve opening actuated. Let gas flow in To the container The second (2) cylinder is divided inside the cylinder into two chambers. The first (57) is where the piston moves in and out. And the second chamber (53) is the control room for the discharge of gas from the gas supply (18) from the outside to flow through the valve to the gas cylinder along the supply pipe (19). They look like air cylinders in general. When air flows from the second valve control module (23) through the air pipe (16) into the fitting (17) along the air pipe (60), push the piston (58). The air inside the first cylinder (57) can be freely vented through the discharge hole (59) to allow for The movement of the piston (58) is easy, there is no air resistance under the piston, there is an O-ring (54) to prevent air from leaking out. The first chamber (57) and the second chamber (53) are separated. There is a partition halfway between the two chambers, where only the piston axis (51) can travel through the partition, with two O-rings (55,56) to prevent leakage. The gas or air coming to push the piston (58) is leaking together through the piston rod (51) .The piston rod (51) inside the emission control chamber (53) is a spring (52) that pushes the rod. Of the piston (51), the piston (58) is in the stroke of the piston (58) next to the wall. At this moment, the spring (52) will be in a slightly recoil state. To make the spring pressure (52) push the valve mouth to close completely. The shaft end (51) also has a spring pusher (52) to depress the spring (52) when the piston rod (51) moves due to a At the end of the piston rod (51) located inside the gas control chamber (53) there is a single O-ring (61) to act as a sealant while the valve flaps are closed. More tightly When the piston moves, it opens the valve mouth to allow the gas supply (18) to flow through the supply pipe (19) into the next gas cylinder.
