Pneumatic hydraulic safety valve applicable range
"Hydraulic safety valve" is widely used in hydraulic power systems and hydraulic equipment safety device, and also can be used as the pressure limiting device, it is a special valve, which is different from conventional valves, conventional valves uses mechanical metal spring as a driving force, only can be limited to medium and low pressure. When meeting the pressure above 10Mpa limit pressure, it can only increase the volume of the booster design, so traditional valves act in the high-pressure and ultra-high pressure hydraulic power systems and hydraulic equipment limit pressure, they will naturally bulky and complicated structure, manufacturing is difficult, high production costs; when using, the metal spring fatigue changes greatly, and limited pressure parameters is volatile, it should be regularly adjusted in order to ensure the normal use. Because spring material steel is large, and can be made by stainless steel and other anti-corrosion materials, products anti-corrosion ability is poor, and the valve service life will not last long.
"Pneumatic hydraulic safety valve" adopts high pressure gas as the power source, changing the proportion of cylinder and valve core head size design, product structure is simple, size is small, limited pressure is stable, and can achieve from 0.1 Mpa to thousands of Mpa of limited pressure, production costs reduce significantly. Through a special designed "Pneumatic Hydraulic safety valve," can act on the supporting shaft of hydraulic pressure system pillar safety valve. In the process of formation pressure bear to achieve slow relief pressure (ie pressure changes with the formation pressure to maintain constant pressure) and fast relief pressure (ie when to the top, it instantaneous relief pressure in a second) so as to ensure equipment non-destructive and personnel safety.
As the "Pneumatic Hydraulic safety valve" has two levels (slow and fast) relief function and limiting function from low to ultra-high pressure; with stable and reliable limited pressure relief pressure and good anti-corrosion performance advantages, the patented product can be greatly enhanced and expanded the hydraulic power systems and hydraulic equipment supporting mine equipment quality and performance. Meanwhile, along with the development of materials technology, it can enable better performance, design of smaller shape hydraulic products is possible. The patent also has reusable inflatable, re-use characteristics, service life is several times more than traditional products.
