"Pneumatic Hydraulic safety valve" is widely used in hydraulic power systems and hydraulic equipment in the safety device, but also can be used as the pressure limiting device, is a special valve, which is different from the traditional valve, traditional valves with mechanical metal spring as a driving force can only be limited to medium and low pressure above the pressure encountered by more than 10Mpa limit pressure can only increase the volume of the booster design, so traditional roles in the high-pressure and high pressure valve hydraulic power systems and hydraulic equipment, pressure-limited, inevitably bulky and complicated structure, manufacturing is difficult, high production costs; in the course of changes in the fatigue of metal spring, Ambassador limited pressure parameters and volatile to be regularly adjusted in order to ensure the normal use. Because of large steel spring material such as stainless steel can not be anti-corrosion materials, products, anti-corrosion ability is poor, the valve life did not last long.
"Pneumatic Hydraulic safety valve" of high pressure gas as the power source, using changes in the proportion of cylinder and valve core size of the head of design, product, simple structure, small size, limited pressure stability, and can achieve from 0.1 Mpa to thousands of The limit Mpa pressure, a significant reduction in production costs. Through a specially designed "Pneumatic Hydraulic safety valve," we can act on the supporting shaft of hydraulic pressure system, pillar of safety valve. In the process of formation pressure to bear to achieve slow to pressure (ie pressure changes with the formation pressure to maintain constant pressure) and fast so that pressure (ie a second cave when the pressure within Xiewan instantaneous relief) so as to ensure non-destructive equipment and personnel.
As the "Pneumatic Hydraulic safety valve" has two levels (slow and fast) function and relieving the pressure from low to ultra-high pressure limiting function; with limited pressure relief and anti-corrosion performance, good stability and reliability advantages, the patent products can greatly enhance and expand the hydraulic power systems and hydraulic equipment supporting mine equipment, quality and performance. Meanwhile, along with the development of materials technology to enable better performance, smaller shape design of hydraulic products possible. The patent also has reusable inflatable, re-use characteristics, useful life several times more than traditional products.
Production conditions: easy to put into the conditions in place, is now limited pressure valve plant can be modified produce, such as the construction of a major new plant investment, 100 million can not meet the market demand, coastal cities and the mainland and the eastern and western regions can have the production conditions.
Cost and profit assessment: With the product enhancements, size is shrinking, the service life extension, production costs and use of cost can be decreased about 50%, so plenty of room for profit within a year recover all the investment. ball valve Trunnion Mounted Ball Valve Floating Ball Valve Top Entry Ball Valve ball valve V Type Ball Valve
