Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the intelligent regulating device of the check valve comprises a valve body 1, one side of the valve body 1 is provided with an air inlet 2, the diameter of the air inlet 2 is three centimeters, the diameter of gas which can pass through the air inlet 2 is three centimeters, the other side of the valve body 1 is provided with an air outlet 3, the top end of the valve body 1 is provided with a regulating port 4, the regulating port 4 is connected with a gas tank, the pressure in the regulating port 4 is consistent with the pressure in the gas tank, the middle of the valve body 1 is movably connected with a valve clack 5, the top end of the valve clack 5 is fixedly connected with a piston rod 6, the piston rod 6 is of a telescopic structure, so that a valve clack spring 7 can be freely compressed and cannot be fixed by the piston rod 6, and the outer side of the piston rod 6 is movably connected with a valve clack spring 7, and the intelligent regulating device is characterized in that: the top end of the piston rod 6 is fixedly connected with a valve opening pressure adjusting flap 8, the valve opening pressure adjusting flap 8 can move up and down in the protruding range of the pipe wall, the movable range is zero to ten centimeters, the elastic force of the valve clack spring 7 can be changed by changing the up-down position of the valve opening pressure adjusting flap 8, and the bottom end of the valve opening pressure adjusting flap 8 is fixedly connected with an adjusting flap spring 9.

The working principle is as follows: connecting the air inlet 2 to the outlet of the gas tank, connecting the air outlet 3 with the gas tank, when the gas in the gas tank is sufficient, the air pressure in the adjusting port 4 is very high, and the valve opening pressure adjusting flap 8 is pressed to the lowest position, at the moment, the elasticity of the valve flap spring 7 is larger, as shown in figures 1 and 2, when in use, the pressure at the air inlet 2 causes the valve flap 5 to overcome the sum of the larger elasticity of the valve flap spring 7, the gravity and the flow resistance of the valve flap 5, so that the valve is opened, when the gas content in the gas pipe is lower, the air pressure in the adjusting port 4 is relatively weaker, so that the valve opening pressure adjusting flap 8 is pushed to the highest position by the adjusting flap spring 9, at the moment, the elasticity of the valve flap spring 7 is smaller, as shown in figures 3 and 4, when in use, the pressure at the air inlet 2 is smaller, but still causes the valve flap 5 to overcome the sum of the smaller elasticity of the valve flap spring 7, the gravity and the flow resistance of the valve flap 5, causing the valve to open.
