"Pneumatic hydraulic safety valve" is widely used in hydraulic power systems and hydraulic equipment in the safety device, but also can be used as pressure limiting device, is a special valve, which is different from the traditional valve, the traditional valve with a mechanical metal spring Power, only limited to low pressure, pressure exceeds 10Mpa pressure limit, can only do to increase the volume of supercharged design, so the traditional valve on the high pressure and high pressure hydraulic power system and hydraulic equipment when the pressure limit Inevitably bulky, complex structure, manufacturing difficulty, high product cost; in the course of the fatigue of the metal spring Ambassador pressure limit fluctuations, frequent adjustments to ensure normal use. As the spring steel material can not be made of stainless steel and other anti-corrosion materials, poor anti-corrosion products, the valve life is not long. "Pneumatic hydraulic safety valve" using high-pressure gas as the power source, the use of change the size of the cylinder head and the proportion of head design, the product structure is simple, small size, pressure limiting stability, to achieve from 0.1 Mpa to thousands of Mpa Limited pressure, product costs significantly reduced. Through the specially designed "pneumatic hydraulic safety valve" can also act on the mine hydraulic support system pressure strut safety valve. In the process of bearing formation pressure, low pressure (ie pressure keeps constant pressure with formation pressure change) and rapid pressure relief (ie instantaneous pressure relief in one second when roof falls) to ensure the equipment is nondestructive and personnel Safety. As the "pneumatic hydraulic safety valve" with two levels (slow and fast) pressure relief function and pressure from low to ultra-high pressure function; with limited pressure relief pressure stable and reliable and good anti-corrosion performance advantages of this patented product Greatly enhance and expand the hydraulic power system and hydraulic equipment, quality and performance of mine support equipment. At the same time with the development of materials technology to make better performance, smaller hydraulic product design solutions possible. The patented product also has a repeatable inflatable, repeated use of the characteristics of the service life is several times the traditional products.
