Abstract

The invention relates to a valve, and discloses a pneumatically controlled angle seat valve. An aluminum alloy upper end cover is connected with an aluminum alloy cylinder barrel through a sealing ring; an observation window is fixed in the center of the aluminum alloy upper end cover; one end of an indicating rod is positioned in the observation window, and the other end of the indicating rod is connected with a locking nut; the locking nut is connected with a valve rod; the valve rod is fixed in the center of a piston; one end of a spring presses against the aluminum alloy upper end cover, and the other end of the spring presses against the piston; an air inlet is positioned on the lower part of the aluminum alloy cylinder barrel; the valve rod is connected with an aluminum alloy lower end cover through an oil bearing; a Y-shaped ring is arranged between the valve rod and the aluminum alloy lower end cover; the aluminum alloy lower end cover is connected with a connecting seat; the connecting seat is connected with a valve body; a macromolecular sealing assembly and a sealing spring are arranged between the valve rod and the connecting seat; the end of the valve rod is connected with a valve core; and the valve core is positioned at the upper end of a valve port. The angle seat valve is compact in structure, safe, reliable, long in service life and easy to manufacture.

Description

technical field [0001] The present invention relates to a valve. Specifically relates to an air control angle seat valve. Background technique [0002] In the domestic market, air-controlled angle seat valves are all made of stainless steel, copper or engineering plastics. The price of stainless steel and copper is relatively high, the casting cycle is long and there is pollution to the environment, and engineering plastics are affected by environmental factors (temperature, humidity, etc.) Larger and dimensionally unstable. Moreover, in terms of structure and surface treatment, the air-controlled angle seat valves sold on the market have problems such as high friction, easy damage, and short life. Contents of the invention [0003] The object of the present invention is to provide an air-operated angle seat valve, which has a compact structure, is safe and reliable, has a long service life and is easy to manufacture. [0004] In order to achieve the above object, the p...
