When measuring lubricating liquids such as oils and fuels, the elliptical gear flowmeter is a common choice due to its reliability and high accuracy. Its accuracy is typically within ±0.5% to ±1%, which is attributed to its positive displacement working principle: the fluid drives two meshed elliptical gears to rotate, and a fixed volume of liquid is discharged with each rotation, thereby achieving stable measurement. Main factors affecting accuracy: 1. Fluid properties: Suitable for clean and lubricating liquids. Liquids containing particles or with high viscosity may affect accuracy; they need to be filtered in advance. 2. Installation conditions: Must be installed correctly as per requirements, ensuring pipe alignment, reducing vibration, and leaving sufficient straight pipe sections. 3. Calibration and maintenance: Regular calibration and maintenance are key to maintaining long-term accuracy. Take the OM-50 model as an example: This model fully demonstrates the advantages of the elliptical gear flowmeter: 1. Capable of measuring viscous…

In the fluid transportation system of the petroleum industry, there is a seemingly simple yet crucial component that is silently safeguarding the safety and efficiency of the pipelines – the right-angle check valve (Angle Check Valve). This specially designed valve, with its unique structure and reliable performance, plays an indispensable role in the fuel storage, transportation, and supply processes. Structure and working principle: A simple and efficient fluid guardian The right-angle check valve adopts a classic right-angle (90-degree) flow channel design. Its interior usually contains a hinged valve disc or a lift-type valve disc. During operation, it relies entirely on the power of the fluid itself: when the pump starts or the upstream pressure is sufficient, the fluid pushes the valve disc open, allowing the medium to pass through; when the pump stops or there is an inverse flow trend, the valve disc, under the action of its own weight,…

The LPG differential pressure valve (also known as the LPG pressure reducing valve) is a specialized valve designed for LPG systems. Its primary function is to reduce the high-pressure gas in the LPG tank to a low-pressure state suitable for use. This valve plays a crucial role in LPG equipment, ensuring the safety and stability of the gas during use. I. Working Principle of LPG Differential Pressure Valve The LPG differential pressure valve regulates the inlet pressure to the required outlet pressure and automatically maintains the outlet pressure stable by relying on the energy of the medium itself. Specifically, when high-pressure gas enters the pressure reducing valve from the inlet, the sealing pad inside the valve is pushed upwards, driving a lever structure to block the gas outlet of the valve, thereby controlling the pressure of the gas flowing out of the valve and preventing it from being too high.…
