A wedge gate valve device for cutting off pipeline pressure is designed at both ends of the dual-connected samplie gate valve. The middle part of the valve body is designed as a square shape. The gate valve, needle valve, and sampling port are designed on the four sides of the square. The use of three-dimensional space is reasonably reduced to shorten the structure length required by the valve body design. It is possible to operate under three different pressures (high pressure, low pressure and no pressure) during the pipeline sampling operation by switching gate valves at both ends.
The resilient seat butterfly valve, also known as a centerline butterfly valve, is a component used for controlling flow and isolating sections in piping systems. The structural feature of the centerline butterfly valve is that the stem axis, the center of the butterfly disc, and the center of the body are all aligned in the same position. This design is simple and easy to manufacture. A common example of this type is the rubber-lined butterfly valve.
The power station swing check valve is mainly suitable for the pipelines of the various systems of thermal power station to prevent the medium from flowing. Compared with other valve products, the power station swing check valve-outbound valve is high -temperature and high pressure. It is a unique and tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The power station swing check valve -type stop valve has the design characteristics of ordinary spinning -type stopping valve. The valve petals rely on the flow of the medium to open and close the valve. Because the valve petals do not rub with the valve seat before closed, the cover wear is reduced to effectively extend the service life of the valve.
