弹簧安全阀

At present, there are a large number of production safety valve spring and leveraged two broad categories.

目前大量生产的安全阀有弹簧式和杆式两大类。

"Hydraulic safety valve" is now widely used in hydraulic power systems and hydraulic equipment in the safety device could also serve as limited pressure device, is a special valve, unlike conventional valves, conventional valves with mechanical metal spring as a driving force, can only be limited to low pressure, the pressure encountered over more than 10Mpa limit pressure can do to increase the volume of the Safety Overflow Valve booster design, the traditional role of the high-pressure valves and high pressure hydraulic power systems and hydraulic equipment The limit pressure of necessity is bulky and complicated structure, difficult to manufacture large, high production costs; in the course of the fatigue of metal spring parameters change fluctuating pressure limiting Ambassador to regular revision to ensure the normal use.

&气动液压安全阀&是目前广泛应用于液压动力系统和液压设备中的安全装置，也可以作限压装置，是一种特殊的阀门，它不同于传统的阀门，传统阀门用机械金属弹簧为动力，只能限中低压力，遇到超过10Mpa以上的压力限压，只能做加大体积的增压设计，因此传统阀门作用于高压和超高压的液压动力系统和液压设备的限压时必然体积笨重，结构复杂，制造难度大，产品成本高；在使用过程中金属弹簧的疲劳变化大使限压参数波动大，要经常调整才能保证正常使用。
