What is a pneumatic safety valve?
Lead:
Safety valves provide safety protection in the system. When the system pressure exceeds the specified value, the safety valve is opened, a part of the gas in the system is discharged into the atmosphere, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause an accident due to excessive pressure. Let me tell you what is a pneumatic safety valve?
The operating pressure determines the nominal pressure of the safety valve, and the operating temperature determines the operating temperature range of the safety valve. The calculated constant pressure value of the safety valve determines the constant pressure range of the spring or the lever, and then determines the material of the safety valve according to the medium used. The structure type, and then calculate the throat diameter of the safety valve according to the relief valve release amount, then what is the role of the safety valve? The safety valve is a safety and protection valve. It is mainly used on pipelines and various pressure equipment. When the working pressure of the medium exceeds the allowable pressure value, the safety valve automatically opens to the external discharge medium. As the medium pressure decreases, ' The safety valve will be closed again to prevent overpressure hazards in pipes and equipment. Do you know what a pneumatic safety valve is?
"Pneumatic safety valve" uses high-pressure gas as the power source, and adopts the design scheme of changing the ratio of the size of the cylinder block and the spool. The product structure is simple, the volume is small, the pressure limit is stable, and the limit from 0.1 Mpa to tens of thousands of Mpa can be realized. Pressure, product costs are greatly reduced.
The specially designed "pneumatic hydraulic safety valve" can also be applied to the pressure-supporting pillar safety valve of the mine hydraulic support system. In the process of receiving formation pressure, the slow pressure is achieved (that is, the pressure maintains a constant pressure with the change of the formation pressure) and the pressure is quickly released (ie, the instantaneous pressure relief is released within one second when the roof is collapsed) to ensure the equipment is non-destructive and personnel. Safety.
Because the "pneumatic hydraulic safety valve" has two levels (slow speed and fast) pressure relief function and pressure limiting function from low to ultra high pressure; it has the advantages of stable pressure limiting pressure relief and good corrosion resistance. Greatly improve and expand the quality and performance of hydraulic power systems and hydraulic equipment mine support equipment. At the same time, with the development of material technology, the performance of the hydraulic product design scheme is better. The patented product also has the characteristics of re-inflatable and repeated use, and the service life is several times that of the conventional product.
