Pneumatic hydraulic safety valve scope of application in production

'pneumatic hydraulic safety valve' is currently widely used in hydraulic power system and safety device of hydraulic equipment & #; Can also be pressure limiting device & #; Is a special kind of pneumatic valve & #; It is different from traditional pneumatic valves & #; Traditional pneumatic valves with powered mechanical spring metal & #; Can only be limited to low and medium pressure & #; Encounter more than Mpa pressure pressure-limiting & #; Can only do increase the volume of pressurization design & #; Traditional pneumatic control valve applied to high pressure and ultrahigh pressure hydraulic power system and the hydraulic equipment when the pressure limiting inevitably heavy volume & #; Complex structure & #; Making difficult
& #; The product cost high; In the process of using metal spring fatigue ambassador fluctuation pressure limiting parameters changed & #; To constant adjustment to ensure the normal use. Due to the high rigidity can't use stainless steel spring materials such as anticorrosive material & #; Poor product anticorrosion ability & #; Pneumatic valve life is not long.
'pneumatic hydraulic safety valve with high pressure gas for power & #; Use change the cylinder block and head proportion to the size of the design of pneumatic valve core & #; The product of simple structure & #; Small size & #; Pressure limiting stable & #; Can be achieved from. Mpa to hundreds of thousands of Mpa pressure limiting & #; The product cost greatly reduced. Through a specially designed 'pneumatic hydraulic safety valve' can also be applied to mine hydraulic support system of pneumatic valve pressure pillar security. In the process of the formation pressure realize slowly let pressure ( The pressure along with the change of formation pressure constant pressure and rapid let pressure ( The roof caving in a second will be discharged pressure transient unloading to ensure the safety of the personnel and equipment condition.
because 'pneumatic hydraulic safety valve has two level ( Slow and fast unloading function from low to high pressure and pressure limiting function; A pressure limiting pressure relief is stable and reliable performance and good advantages & #; This patented product can greatly improve and expand the hydraulic power system and hydraulic equipment of mine support equipment quality and performance. At the same time with the development of material technology make better performance & #; Form a smaller hydraulic product design possible. This patented product has repeatable inflated, the repeated use of the characteristics & #; Life is a traditional product several times.
production requirements: production condition tend to have & #; Now limited pressure pneumatic valve factory can retrofit production & #; Such as building a big new factory investing hundreds of millions of also can't meet the demand of market & #; Coastal cities and inland and eastern and western regions can meet production conditions.
the cost and profit evaluation: with the augmentation of the product features & #; Volume reduction & #; The extension of service life & #; The cost of production and use of costs could be falling by % & #; So the profit space is very big & #; Can recover all the investment in a year.
