Embodiment 1

[0023] Such as figure 1 As shown, the present invention discloses an air booster main engine with a combined air valve, including a main engine base 1, a crankshaft unit 2 is installed in the main engine base 1, and one end of the crankshaft unit 2 is connected with a drive shaft protruding from the main engine base. 1 The transmission shaft outside the casing, one end of the crankshaft unit 2 is rotationally connected to one end of several connecting rods 4, the other end of the connecting rod 4 is connected to a piston 5, and the top of the main engine base 1 is installed with several pistons that cooperate with the piston 5 Cylinder unit, the piston unit includes a first piston cylinder 6, a second piston cylinder 7, a combined air valve 8 and a cylinder cover 9, the bottom of the first piston cylinder 6 is connected to the base 1 of the main engine, and the inner edge of the top of the first piston cylinder 6 A groove is provided, and a sealing ring 10 is installed in the ...

Embodiment 2

[0026] Such as Figure 1-5 As shown, the present invention discloses an air booster main engine with a combined air valve, including a main engine base 1, a crankshaft unit 2 is installed in the main engine base 1, and one end of the crankshaft unit 2 is connected with a drive shaft protruding from the main engine base. 1 The transmission shaft 3 outside the casing, one end of the crankshaft unit 2 is rotationally connected with one end of several connecting rods 4, the other end of the connecting rod 4 is connected with a piston 5, and the top of the main engine base 1 is installed with several pistons that cooperate with the piston 5 The piston cylinder unit is characterized in that: the piston unit includes a first piston cylinder 6, a second piston cylinder 7, a combined air valve 8 and a cylinder cover 9, the bottom of the first piston cylinder 6 is connected with the main engine base 1, and the first piston cylinder The inner edge of the top of 6 is provided with a groov...

Embodiment 3

[0027] Embodiment 3: On the basis of Embodiment 2, the vent hole 14 is provided with a valve 16 for one-way ventilation. The valve 16 is cracked with several arc-shaped cracks 17 from the center to the periphery, and the edge of the valve 16 extends upwards. Install the membrane 18, as shown in the figure, the air can be discharged from the slit 17 as shown by the arrow of the one-way discharge of the airflow. When the function of closing the exhaust hole when the control valve plate contacts the installation plate fails, the air cannot pass through the one-way valve 16, which means The valve 16 assumes the function of closing the exhaust hole in the second stage.

[0028] The hole wall of the exhaust hole 14 is provided with an external thread, and an installation ring 19 cooperating with the external thread is also installed on the exhaust hole 14. The installation film 18 is fixedly connected between the installation ring 19 and the external thread, and the installation is f...

Abstract

The invention discloses an air supercharging main machine with combined air valves. The air supercharging main machine comprises a main machine base, a crankshaft unit is arranged in the main engine base, one end of the crankshaft unit is connected with a transmission shaft of which a driving shaft extends out of a shell body of the main machine base, one end of the crankshaft unit is rotatably connected with one ends of a plurality of connecting rods, the other ends of the connecting rods are connected with pistons, a plurality of piston cylinder units matched with the pistons to move are installed at the top of the main machine base, each piston cylinder unit comprises a first piston cylinder, a second piston cylinder, one combined air valve and a cylinder cover, the bottoms of the first piston cylinders are connected with the main machine base, and grooves are formed in the inner side edges of the tops of the first piston cylinders, and sealing rings are installed in the grooves. According to the air supercharging main machine with the combined air valves, overhauling by an operator is conveniently carried out, and meanwhile the operation working condition of the main machine is improved.

Description

technical field [0001] The invention relates to an air booster accessory, in particular to an air booster main engine with a combined air valve. Background technique [0002] The air booster is a driven fluid machine that lifts low-pressure air into high-pressure air, and is the heart of the compressed air system. It inhales low-pressure compressed air from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-pressure compressed air to the exhaust pipe, serving various industries and departments that use high-pressure compressed air. [0003] If the existing air booster main engine adopts the piston unit as the mechanism for inputting and outputting air, if the main engine uses a piston with a long stroke to move, some manufacturers use an integrated long cylinder body, which is not conducive to the maintenance and repair of the piston cylinder; in addition, Piston movement requires a more superior switch structure for e...
