Types and characteristics of slag valve of knife gate valve

Knife gate valves are divided into many types, the more typical of which is the slag valve. Only the slag valve is not related to the knife gate valve in its name, but it belongs to the category of knife gate valves. In general fluid piping systems, the drain The slag valve is a control element, and its main function is to isolate equipment and piping systems, and can adjust flow, prevent backflow, and drain fluid pressure. Therefore, in this case, the slag valve is more important. Let's understand the characteristics of the slag valve. By understanding the characteristics, we will further understand why we use it and what are the benefits of using it? In this way, all the questions will be easily solved.

The characteristics of the slag discharge valve have its use characteristics: it determines the main performance and scope of use of the slag discharge valve. The characteristics of the valve use include: valve category (closed circuit valve, regulating valve, safety valve, etc.); product type (gate valve) , Globe valve, butterfly valve, ball valve, etc.); the materials of the main parts of the valve (valve body, bonnet, valve stem, valve clack, sealing surface); drive mode of the slag valve, etc. Structural characteristics: It determines some structural characteristics of the installation, repair, maintenance and other methods of the slag discharge valve. The structural characteristics include: the structural length and overall height of the valve, the connection form with the pipeline (flange connection, threaded connection, clamp Hoop connection, external thread connection, welding end connection, etc.); the form of the sealing surface (inlay ring, thread ring, surfacing, spray welding, valve body); the structure of the valve stem (rotating rod, lifting rod), etc.

The above is the content of the type and characteristics of the slag valve of the knife gate valve introduced for you. If you have any questions about this, please come to consult our website, and we will have a professional person to explain it for you.
