The butt-weld butterfly valve is a type of valve that connects pipes through welding. It is mainly used for fluid control. Its structure is simple, lightweight, and easy to operate. It has advantages such as excellent sealing performance, flexible operation, and space-saving. It is widely used in industries such as petroleum, chemical engineering, water supply, drainage, and water treatment.
The working principle of the butt-weld butterfly valve is to regulate the flow of fluid by rotating the valve plate. The rotation angle is generally between 0° and 90°. It is flexible to rotate and reacts quickly. The valve body is usually made of materials such as cast iron and stainless steel, with good corrosion resistance and high-temperature resistance. The valve plate is commonly designed as a circular disc shape or an elliptical shape, which can effectively reduce fluid resistance and improve flow efficiency.
The main features of the butt-weld butterfly valve are:
Compact structure, small size, light weight, flexible operation, and convenient use.
It adopts three-dimensional eccentric elastic or multi-layer hard sealing structure, with reliable sealing performance and can achieve zero leakage.
Without flange design, it brings convenience and beauty to the pipeline and insulation wrapping.
It has the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance.
Purpose
For use in the sulfuric acid industry for gas pipelines: inlet and outlet of the pre-combustion blower, inlet and outlet of the interlock blower, the series and connecting valves of the electro-dewashing system, inlet and outlet of the main blower for SO2, the adjustment of the converter, inlet and outlet of the preheater, etc.For use in the sulfuric acid industry for gas pipelines: inlet and outlet of the pre-combustion blower, inlet and outlet of the interlock blower, the series and connecting valves of the electro-dewashing system, inlet and outlet of the main blower for SO2, the adjustment of the converter, inlet and outlet of the preheater, etc. for regulating and controlling the gas volume.
