Globe valve uses and advantages and disadvantages

The use of globe valves is as follows: Globe valves are used in most media flow systems. Has developed to meet the petrochemical, electricity, metallurgy, urban construction, chemical and other sectors of the various forms of the globe valve. The use of stop valves is extremely common, but the larger the opening and closing torques, the longer the length of the structure, usually the nominal diameter is limited to below 250mm, but also to 400mm, but the choice of special attention to import and export direction. Most of the following 15Omm most of the cut-off valve media most of the inflow from the valve below, and more than 2O0mm most of the globe valve medium inflow from the top of the valve. This is due to the closing torque of the valve. In order to reduce the opening or closing torque, generally more than 2O0mm off valve are provided within the bypass or bypass valve. The most obvious advantages of the stop valve are: (l) During the opening and closing process, the wear resistance is achieved due to the smaller friction between the valve disc and the sealing surface of the valve body than the gate valve. (2) The opening height is generally only l / 4 of the diameter of the valve seat passageway and is therefore much smaller than the gate valve. (3) Usually there is only one sealing surface on the valve body and the valve flap, so the manufacturing technology is relatively good and easy to maintain. However, the shortcomings of the globe valve can not be ignored. The main disadvantage is the large flow resistance coefficient, resulting in pressure loss, especially in the hydraulic device, this pressure loss is particularly evident.

Home Appliance Steel

In the field of home appliances, prepainted steel is widely used for a variety of reasons. Let's take a closer look at some of the applications of prepainted steel in home appliances.

Refrigerators

Refrigerators are one of the most common home appliances that use prepainted steel. The exterior panels of the fridge are typically made from prepainted steel, which gives them a smooth, glossy finish that is easy to clean and maintain. The steel is also coated with a layer of protective material that helps to prevent corrosion and keep the fridge looking new for years.

Washing Machines

Washing machines are another home appliance that often uses prepainted steel. The drum, cabinet, and other external parts of the washing machine are typically made of prepainted steel. This material provides a durable and long-lasting finish that is resistant to scratches and other damage, making it ideal for use in a busy household.

Air Conditioners

Air conditioners use prepainted steel for their exterior panels, which not only provides a sleek and modern look but also protects the unit from the elements. The steel is coated with a layer of protective material that helps to prevent rust and corrosion, ensuring that the air conditioner lasts for many years.

Ovens and Ranges

Prepainted steel is also commonly used in the production of ovens and ranges. The exterior panels of these appliances are typically made from prepainted steel, which gives them a durable and long-lasting finish that is resistant to scratches, stains, and other damage. The steel is also coated with a layer of protective material that helps to prevent corrosion and rust, ensuring that the oven or range looks new for years.

In conclusion, prepainted steel is a versatile and durable material that is widely used in the field of home appliances. Its protective coating not only provides a decorative finish but also protects the steel from rust and corrosion, making it an ideal material for a range of applications. From refrigerators to washing machines, air conditioners to ovens and ranges, prepainted steel plays a crucial role in the production of these essential household appliances.2021093003560795
