The butterfly valve is a valve type composed of a disc, a stem, a seat and a box body. The structure is simple and the price is relatively low. It is mainly used for opening and closing or throttling. The butterfly plate of this valve is mounted on the steel plate and is driven by the stem to rotate around its own axis, so that its distance from the valve seat is changed, so as to realize the opening and closing or adjusting of the flow channel.
New high-life stainless steel materials butterfly valve mainly refers to the butterfly valve improved on the basis of traditional butterfly valve materials, by improving the material quality, longer service life and better product performance. The body and disc are made of stainless steel plates, and the seat and bearing parts are made of materials with better wear resistance and lubrication property.
The external part of the new high-life stainless steel butterfly valve is mainly composed of three parts: valve body, butterfly plate and valve stem. Among them, the valve body is a box-shaped structure with ports on both sides, which transmits media pressure. The butterfly plate is connected with the valve core and is rotated around the axis of the butterfly plate center to open and close or adjust the flow rate. The valve stem drives the butterfly plate to rotate, open and close, and has a position indicating device for checking the valve opening and closing and adjusting position.
The material selection of the new high-life stainless steel butterfly valve is very important, especially the butterfly plate and seat material. The stainless steel plates used for the body and butterfly plate can improve the corrosion resistance and wear resistance of the valve body and extend the service life of the valves. In addition, the seat must select high wear-resistant materials, such as ceramic, PTFE, etc., in order to improve the service life and performance of the valves.
Furthermore, the structure of the new high-life stainless steel butterfly valve is also a key. The butterfly valve is usually connected by flange connection. The flange of the valve can not only increase the strength of the connection, but also be easily connected to other equipments. At the same time, the correct installation angle of the butterfly plate can also help to reduce the wear of the valve and the increase of the flow resistance, thus prolong the service life of the valve.
In addition, the implementation of sealing is also very important for the new high-life stainless steel butterfly valve. The sealing performance of the valve is related to the production process and the environmental conditions of the user. The good sealing performance depends on the self-innovative structure of the inner cavity of the valve and the installation method of the valve seat. It is also affected by the external conditions of the valve, such as the degree of common interconnection and the degree of vibration, if these conditions are not reached, it may not guarantee the sealing performance.
Finally, the use of the new high-life stainless steel butterfly valve also requires operators to pay attention to the correct maintenance. It is mainly to rinse the valve body with a small amount of chemical solution when it is used, and pay attention to check the valve stem, valve core, valve body and other parts regularly. In addition, the stem gland and related parts should be checked to avoid water leakage.
Through the introduction of stainless steel butterfly valve and its relevant precautions, it is hoped that readers can have a more comprehensive understanding of this product and use it correctly. New high-life stainless steel butterfly valve is a kind of valve with good performance and long service life. It can be applied in many fields and bring good economic benefits to users.
