Gate Valve is a safety device currently widely used in hydraulic power systems and hydraulic equipment. It can also be used as a pressure limiting device. It is a Special Valve. It is different from traditional valves. Traditional valves are powered by mechanical metal springs and can only limit For medium and low pressures, when the pressure limit exceeds 10Mpa, only a larger volume boosting design can be made. Therefore, traditional valves must be bulky and bulky when used to limit the pressure of high-pressure and ultra-high-pressure hydraulic power systems and hydraulic equipment. Complex, difficult to manufacture, and high product cost.
During use, the fatigue changes of the metal spring cause the pressure limiting parameters to fluctuate greatly, and frequent adjustments are required to ensure normal use. Since the spring material has high rigidity and cannot be made of anti-corrosion materials such as stainless steel, the product has poor anti-corrosion ability and the service life of the valve is not long.
The
Universal Valve uses high-pressure gas as the power source, and adopts a design scheme that changes the ratio of the cylinder body and the valve core. The product has a simple structure, a small size, and stable pressure limiting. It can realize pressure limiting from 0.1 Mpa to thousands of Mpa. The product Costs are significantly reduced. The specially designed Universal Valve can also be used as the pressure-bearing pillar Gate Valve of the mine hydraulic support system. In the process of withstanding formation pressure, slow pressure yielding and rapid pressure yielding are achieved to ensure no damage to equipment and personnel safety.
Since the Universal Valve has a two-level pressure relief function and a pressure limiting function from low to ultra-high pressure; it has the advantages of stable and reliable pressure limiting and pressure relief and good anti-corrosion performance. This patented product can greatly improve and expand the hydraulic power system and hydraulic pressure. EquipmentThe quality and performance of mine support equipment. At the same time, with the development of material technology, it is possible to design hydraulic products with better performance and smaller size. This patented product also has the characteristics of being re-inflatable and usable repeatedly, and its service life is several times that of traditional products.
