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, an air control conjoined valve sequentially comprises a window, a window O-ring, an indicating rod, a spring, a lock nut, a cylinder, a piston ring, a piston O-ring, a piston gasket, an oil-containing bearing, an end cover O-ring, a check ring, a sealing spring, a gasket I, a connection, a valve body sealing gasket, a valve rod, a valve body, a valve core sealing gasket, a self-locking nut, a second air inlet, a second air control cavity, a first air inlet, a first air control cavity, an end cover Y-ring, a gasket II, a pressure ring, a U-shaped rubber ring, a U-shaped tetrafluoride ring and; the end cover and the cylinder form an upper control part, and a window, a window O-shaped ring, an indicating rod, a spring, a locking nut, a piston ring, a piston O-shaped ring, a piston gasket, an oil-containing bearing, an end cover O-shaped ring, an end cover Y-shaped ring and a check ring are arranged in the upper control part; the middle connecting sealing part is composed of the connecting and valve body and the end cover, and is internally provided with a sealing spring, a gasket I, a valve rod, an end cover Y-shaped ring, a gasket II, a pressing ring, a U-shaped rubber ring, a U-shaped tetrafluoride ring and a guide ring; the valve core and the valve body form a lower execution part, and a valve body sealing gasket, a valve rod, a valve core sealing gasket and a self-locking nut are arranged in the lower execution part; the side wall of the cylinder is provided with an upper air inlet and a lower air inlet, and the first air inlet and the second air inlet are respectively connected with an external air source; the first air control cavity or the second air control cavity can be internally provided with a spring; the valve body is communicated with the two straight ends, and the vertical end is closed by the valve core to form an upper channel and a lower channel; a sealing spring is arranged below the end cover, the lower end of the sealing spring is fixed in the connecting sealing cavity, the upper end of the sealing spring is fixed with the end cover, and the sealing spring is always in a compressed state to promote the long-term sealing of the middle sealing assembly; the valve body interface comprises two end interfaces and a lower interface, namely an interface form connected with a pipeline, can be in threaded connection, quick-assembly connection, welding connection and rhombic flange connection, can meet the connection requirement of more than 95% of the current working condition occasions, can be selected according to the actual requirement, and is not limited 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 plug gasket to leave the sealing surface of the valve body, the valve is opened, the medium moves from fig. 2 to fig. 3, enters the A, B chamber from the C end, and then enters the pipeline from the A, B common chamber, thereby completing the opening operation 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 part, the gas in the first air control cavity is discharged through the first air inlet, the valve core sealing gasket is pushed to move to the sealing surface of the valve body by the linkage of the piston and the valve rod, the valve is closed, the medium is blocked at the lower side of the C end of the valve body, namely the valve moves to the state shown in the figure 2 from the figure 3, 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 conjoined valves are used as a valve group together, the spring force value of the conjoined valves 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.
