Applications Hydraulic safety valve

Hydraulic valve is widely used in hydraulic power systems and hydraulic equipment safety devices, but also can be used as pressure limiting device, is a special valve, which is different from the conventional valve, conventional mechanical valve metal spring as a driving force, only Low pressure can limit encountered more pressure than 10Mpa limit pressure, can only increase the volume of pressurized to do design, traditional pressure limiting valve acts on the high pressure and ultra-high pressure hydraulic power systems and hydraulic equipment necessarily bulky , complex, difficult to manufacture large, high production costs; in the course of large metal spring fatigue change ambassador pressure limiting parameter fluctuations, often adjust in order to ensure normal use. Since large steel spring material can not be anti-corrosion materials such as stainless steel production, poor product corrosion resistance, valve life is not long.
"Pneumatic valve" using high-pressure gas as power source, use to change the size of the cylinder head and Natural Gas Safety Valve body proportion design, product structure is simple, small size, limited pressure stability can be achieved from 0.1 Mpa Mpa of thousands limit pressure, significantly reduce product cost. By "pneumatic safety valve" effect also specially designed pillar pressure gas cooker safety valve in the hydraulic mine support system. Achieve a slow process of formation pressure to bear so that the pressure (that varies with the pressure to maintain a constant pressure formation pressure) and fast so that the pressure (ie, roof collapse pressure instantaneous relief emptied within one second) in order to ensure that equipment and personnel lossless Security.
