Product Description:
Pressure relief valves are essential safety devices designed to protect silos from overpressure or vacuum conditions that could lead to structural damage. These valves act as a final safeguard, ensuring that any sudden pressure changes are managed quickly and effectively. Although ideally they should never need to activate, their reliability and performance under critical conditions are crucial for system integrity. VCP Pressure Relief Valves have been widely used across the globe and are known for their high level of performance and durability in various environments. For applications in the food industry, there is an option available that complies with European Regulation (EC) No. 1935/2004, ensuring food-grade compliance and safety.
Key Features:
- Waterproof design using stainless steel and engineering plastics
- Valve plate made of carbon steel or stainless steel, combined with a black sealing rubber mat
- Valve body constructed from carbon steel with surface coating or stainless steel
- Connection options include flange connections with gaskets, embrace hoop connections with seals
How It Works:
The valve operates using helical springs that keep the lid closed when the internal pressure remains within the set limits. Three external spring rods maintain the closure of the outer ring-shaped lid until the internal pressure exceeds the spring force. When this happens, the lid lifts, allowing excess pressure to escape. A smaller central lid covers the opening from below, held in place by a single spring rod and pressed against the outer lid by normal air pressure. During suction conditions, the spring compresses, allowing the lid to drop and let air in, restoring pressure balance and returning the lid to the closed position. For use in sensitive environments like the food industry, an ATEX-certified and EC-compliant version is also available.
Additional Features:
- ATEX-certified model for explosive environments
- Complies with European Regulation (EC) No. 1935/2004
- Customizable pressure settings available
- Includes inspection hatch for maintenance access
- Equipped with inductive sensors for monitoring
- Bird net included for protection against external elements
Technical Parameters:
Tungsten Alloy For Oil Logging
Tungsten alloy is an ideal material for oil logging due to its high density, excellent corrosion resistance, and good mechanical properties. Oil logging is a process of measuring the porosity, permeability, and fluid content of rocks in the subsurface to evaluate the potential for oil and gas production.
Tungsten alloy is used in oil logging tools such as gamma ray detectors, density logging tools, and neutron porosity tools. These tools are used to measure the characteristics of the subsurface rock formations and determine the presence of oil and gas reserves.
The high density of tungsten alloy enables the tools to penetrate deep into the earth's crust and accurately measure the properties of the rock formations. Additionally, tungsten alloy is highly resistant to corrosion, which is critical in harsh environments such as oil fields.
Furthermore, tungsten alloy has excellent mechanical properties, including high strength and toughness, which make it suitable for use in downhole tools that are subjected to high pressure and temperature.
In summary, tungsten alloy is an ideal material for oil logging due to its high density, excellent corrosion resistance, and good mechanical properties. Its use in oil logging tools enables accurate measurement of subsurface rock formations and identification of potential oil and gas reserves.
