The globe valve is used to cut off the flow of the medium. The globe valve is suitable for frequently opened occasions. The sealing parts of the globe valve are the disc and the valve seat. In order to make the globe valve close tightly, the mating surface of the disc and the valve seat should be grinding or using gaskets. The sealing surface can also be inset with bronze, stainless steel and other corrosion-resistant and wear-resistant materials. The disc and stem of the globe valve are connected with each other, so that the disc and stem are closely fitted. The lifting of the disc of the globe valve is generally controlled by the stem. The upper part of the stem of the globe valve is the handwheel, and the middle part is the thread and packing sealing section. The role of the packing is to prevent the internal medium of the valve body from leaking along the stem.

LED fluorescent lamps are becoming more and more common in daily life due to their unique benefits. Let’s explore what makes them so special.
First, unlike traditional fluorescent lamps, LED lamps don’t contain mercury or lead. Traditional lamps release harmful mercury vapor when broken, which can damage the environment. LED lamps are considered a green lighting solution because they are safe and eco-friendly.
Second, LED lamps are cold light sources, meaning they produce very little heat compared to traditional bulbs. This means almost all the electricity is converted into light, making them highly energy-efficient and cost-effective in the long run.
Third, these lamps operate silently, unlike traditional fluorescent lights that often hum or buzz. This makes them perfect for quiet spaces like libraries, offices, and bedrooms. They also provide smooth, flicker-free lighting, which is easier on the eyes and better for your overall health.
Additionally, LED lamps do not emit ultraviolet or infrared light, and they don’t contain harmful substances like mercury. They also generate less heat, which helps reduce the number of insects attracted to the light. This contributes to a cleaner and more comfortable indoor environment.
Lastly, LED lamps have an exceptionally long lifespan—over 30,000 hours—while using less than one-third the energy of traditional fluorescent lamps. Their brightness remains consistent over time, so you won’t need to replace them as often. This reduces maintenance costs and is ideal for hard-to-reach areas. Plus, they come in a wide range of colors, allowing you to choose the perfect lighting for any space or occasion.
