Many valves have been installed, using the main purpose and elasticity, stronger control of the valve, then the valve installation of stainless steel spring can have what role?

The key of the valve is composed of the valve core, high pressure gate valve, valve seat, elastic yellow, adjusting screws, etc., and this kind of valve is mainly the use of stainless steel plate spring elastic force to press the valve core on the high pressure gate valve. When the working pressure of the valve exceeds the working pressure at the heart of the valve, the valve core and the valve seat are jacked up and the steam is discharged; When the valve is less than the working pressure at the heart of the valve, the valve core lands on the high pressure gate valve, and the heating furnace terminates the exhaust steam.

The surface of valve core and high pressure gate valve is spherical, and there is a small amount of overhang around the edge of valve core. When the steam top opens the valve core, the edge of the valve core is also affected by the effect of pressure, so that the total area of effect is suddenly increased, the valve suddenly opens; When the drop force is reduced, the steam interaction force is suddenly reduced, so that the valve core is closed once to avoid constant vibration of the valve core. The basic parameters of elastic yellow valve are open working pressure and exhaust working capacity, and exhaust working capacity lies in high pressure gate valve specifications and valve core to improve the aspect ratio. Because the height-width ratio is not the same, it can be divided into three kinds: full-start valve, middle-start valve and full-start valve.

Stainless steel spring valve compact structure, small size, lightweight; Good sealing, and convenient adjustment, withstand vibration, very few leakage conditions. Therefore, dexterity is reliable. It is the most widely used and is the most common.

The raw material cross section of spiral single spring should be preferentially selected with annular cross section. Square and rectangular frame cross section raw materials, strong bearing capacity, good impact resistance, and can make the yellow miniaturization, but the raw materials are from a small number. Rectangular mold spring manufacturers and the price is high, in addition to unique must, generally do not use such raw materials as far as possible. In recent years, research and development of round stainless steel wire rolling flat instead of ladder stainless steel wire, obtained very good practical results.
