Embodiment Construction
[0010] Such as figure 1 As shown, a device for actuating an air valve by a cylinder piston includes a base 1 and an air valve 2. A first air intake pipe 21, a second air intake pipe 22, and an exhaust pipe 23 are arranged on the air valve 2. Rod 3, air valve ejector rod 4, tappet spring 5 and the spring seat connected to the tappet 3, one end of the tappet 3 is slidingly connected with the air valve ejector rod 4 and can push the air valve ejector rod 4, and the other end is Set as a plane capable of bearing force, the tappet spring 5 is penetrated on the tappet 3, one end of the tappet spring 5 is supported under the air valve push rod 4, and the other end is supported on the spring seat.
[0011] When adopting the above technical scheme, when the piston 7 of the cylinder 6 compresses the gas, the air pressure in the cylinder 6 rises, and when the force acting on the plane where the tappet 3 is stressed is greater than the resistance of the tappet spring 5, the tappet 3 Move...

The invention relates to an air valve starting and stopping device, in particular to an air valve starting device of a piston of an air cylinder. The air valve starting device comprises a base and an air valve and is additionally provided with a tappet rod, an air valve ejector rod, a tappet rod spring and a spring seat. A first air inlet pipe, a second air inlet pipe and an exhaust pipe are arranged on the air valve, the air valve, the spring seat is connected onto the tappet rod, one end of the tappet rod is slidably connected with the air valve ejector rod and can push the air valve ejector rod, a plane capable of bearing force is arranged at the other end of the tappet rod, the tappet rod spring is arranged on the tappet rod, one end of the tappet rod spring is carried under the air valve ejector rod, and the other end of the tappet rod spring is supported on the spring seat. The air valve starting device has the advantage that the service life of the air valve can be prolonged.
Description
technical field [0001] The invention relates to an opening and closing device for an air valve, in particular to a device for actuating an air valve by a cylinder piston. Background technique [0002] Ordinary cylinders are mainly composed of cylinders, pistons, piston rods, front and rear end covers, and seals. This type of cylinder is the most widely used and is generally used in packaging machinery, food machinery, processing machinery and other equipment. The gas valve is an important component on the piston compressor cylinder, which is responsible for the suction and discharge of gas. [0003] Existing air valves are usually composed of valve seats, valve plates, springs, lift limiters, bolts, etc., and piston compressors generally use "automatic valves", that is, the opening and closing of the air valves depends on both sides of the valve plate. The valve plate controls the opening and closing of the air valve, and the valve plate is easily deformed or damaged under ...
