Detailed Description

The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1-3, a small-bore pneumatic control filling valve sequentially comprises a cylinder, a spring, a lock nut, a piston O-ring, an end cover O-ring, a cylinder O-ring, a hole retainer ring, an end cover, an oil-containing bearing, a connection sealing gasket, a connection Y-ring, a connection guide sleeve, a valve rod, a gland, a valve core sealing gasket, a valve core gasket, a split ring, a valve body sealing gasket, a filling pipe, a screw sleeve, a filling pipe sealing gasket, a filling connecting pipe, a second air inlet, a second pneumatic control cavity, a first air inlet, a feed inlet and a filling port; the end cover and the air cylinder form an upper control part, and a spring, a locking nut, a piston O-shaped ring, a valve rod, an end cover O-shaped ring, a cylinder barrel O-shaped ring and a check ring for holes are arranged in the upper control part; the connecting and valve body, the filling pipe and the filling connecting pipe form a lower executing part, and an oil-containing bearing, a connecting and connecting sealing gasket, a connecting Y-shaped ring, a connecting guide sleeve, a valve rod, a gland, a valve core sealing gasket, a valve core gasket, a split ring, a valve body sealing gasket, a screw sleeve and a filling pipe sealing gasket are arranged in the lower executing part;

as shown in fig. 1, the valve core and the valve rod form a lower sealing part, the upper part of the valve core is provided with a flange, and the lower part of the valve core is provided with a valve core sealing gasket, a valve core gasket and a split ring, wherein the valve core sealing gasket, the valve core gasket and the split ring belong to fixed valve core sealing and have the characteristics of reliable execution and accurate seat return; the first air control cavity or the second air control cavity can be internally provided with a spring, the spring is arranged in the first cavity and is a normally open valve, and the spring is arranged in the second cavity and is a normally closed valve; the filling pipe and the filling connecting pipe are externally provided with screw sleeves, and the filling pipe sealing gasket is arranged in the filling pipe, so that the filling pipe and the filling connecting pipe can be connected with the filling connecting pipe with the diameter of less than 12, and the filling pipe and the filling connecting pipe are very convenient to disassemble and replace; the valve body feed inlet, the interface form that links to each other with the pipeline promptly can have threaded connection, fast-assembling joint connection, can satisfy the connection demand under the present more than 95% filling trade occasion, and this point can be selected for use according to actual needs, does not do the restriction here.

In this embodiment, as shown in fig. 1, 2, and 3, a spring is disposed in the second pneumatic control chamber, compressed air is introduced from the first air inlet, the air pushes the piston to move upward against the spring force, and the second air inlet discharges the air in the second pneumatic control chamber, so that the piston drives the valve rod to pull the valve core sealing gasket to leave the sealing surface of the valve body, the valve is opened, the medium moves from fig. 2 to fig. 3, the medium enters from the feed inlet, and the filling port of the filling adapter is filled into the filling container to complete the opening and filling actions of the valve; the introduced compressed air is removed from the first air inlet, the piston is forced to move downwards due to the elastic force of the spring on the upper portion, the gas in the first air control cavity is discharged through the first air inlet, the piston is linked with the valve rod to push the valve core sealing gasket to move to the sealing surface of the valve body, the valve is closed, the medium is blocked in the valve body, the liquid at the lower end of the sealing surface is adsorbed in the pipe due to the small pipe diameter, namely the liquid moves from the graph 3 to the graph 2, the closing action of the valve is completed, and the two groups of actions are the opening and closing action of the valve.

However, in the actual use process, the spring is a very important reaction component, and particularly when a plurality of filling valves are used together for filling, the spring force value of the spring is related to the accuracy, reliability and timeliness of the whole valve, so that the requirements on the stability and the service life of the spring force value are very high, but because inevitable deviation and limitation exist in the manufacturing process of the spring, a more reliable execution mode is usually selected in the actual use, and the spring is installed and compressed air is used for performing simultaneously, so that the more reliable opening and closing actions of the valve are realized.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
