Pressure relief valve function and classification

First, the function of relief valve: constant pressure overflow effect: In the metering pump throttling regulation system, the dosing pump provides a constant flow. When the system pressure increases, will reduce the demand for traffic. At this point, the relief valve is opened to allow excess flow to overflow into the fuel tank to ensure that the relief valve inlet pressure is constant, ie the pressure at the pump outlet is constant (the valve port often opens with pressure fluctuations). Overflow valve diagram Safety protection: The valve is closed when the system is working normally. Only when the load exceeds the specified limit (the system pressure exceeds the set pressure), the overflow will be opened and over load protection will be implemented to prevent the system pressure from increasing (usually, the setting pressure of the relief valve is 10% ~ 20% higher than the maximum working pressure of the system. ). 1, for unloading valve; 2, for remote pressure regulating valve; 3, for high and low pressure multi-stage control valve; 4, for the sequence valve; 5, used to generate back pressure (string in the return line). Second, the classification of relief valve: 1, direct acting relief valve: (1), cone valve direct acting relief valve (2), ball valve direct acting relief valve 2, pilot relief valve Main valve and pilot valve composed of two parts. Pilot valve similar to the direct acting relief valve, but usually cone valve (or ball valve) shaped seat structure. The main valve can be divided into a concentric structure, two concentric structure and three concentric structure.

Magnetic Track Light

We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting

Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.

While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
