Ordinary electric motors are designed according to constant frequency and voltage, and cannot fully meet the requirements of frequency converter speed regulation. Therefore, they cannot be used as more frequency conversion motors 1、 The impact of frequency converters on motors mainly lies in their efficiency and temperature rise. The frequency converter can generate varying degrees of harmonic vol...

Ball valve structure There are many types of structures for ball valves, but they are basically the same. They are all round ball cores with opening and closing parts, mainly composed of valve seats, balls, sealing rings, valve stems, and other driving devices. The valve can be opened and closed by rotating the valve stem 90 degrees. They are used in pipelines to shut off, distribute, regulate flo...

The valve body is the main component of a valve, which serves to connect and support other parts of the valve, as well as withstand pressure. The valve body type refers to the structural design type of the valve, which is usually divided into multiple types based on its appearance and purpose. Classification by appearance 1. Straight-through valve body: The flow channel is smooth and the pressure ...

Stop valve, also known as shut-off valve, belongs to the forced sealing type valve and is a type of shut-off valve. There are three types of connection methods: flange connection, screw connection, and welding connection. The "three modernizations" of valves in our country once stipulated that the flow direction of shut-off valves should be from top to bottom, so there is directional installation....

The bellows globe valve, also known as the bellows sealed globe valve, is designed with automatic roll welding to form a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem. The internal structure of the bellows globe valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded to the valve stem to prevent process fluid...

A globe valve is a type of valve that uses the valve disc to move along the center of the valve seat channel to control the opening and closing of the pipeline. The working principle of a shut-off valve is to change the flow area of the pipeline through the rotation or lifting movement of the valve disc, thereby controlling the flow rate and pressure of the medium. When the valve disc is closed, i...
