The Difference Between One-piece, Two-piece And Three-piece Sanitary Ball Valves
Sanitary Ball Valve is indispensable in pipeline projects that directly contact food, and is closely related to food health. Wenzhou Huadun produces sanitary ball valves with smooth surfaces to ensure cleanliness, no medium accumulation area, and no potential pollution. It can meet the special requirements of various media in the food and biopharmaceutical fields. The smooth, seamless, and automatically emptied manual fluid channel of the sanitary valve is also very suitable for the need of steam stepping on it for on-site cleaning. The material will be selected as 304 or 316, and its inner surface is highly smooth, which is conducive to the flow of fluid media and reaches the sanitary level. This is irreplaceable by industrial ball valves. Connection method Sanitary ball valves generally use clamps for quick installation and threaded connection; while the connection methods of industrial valves include flanges, threads, quick installation, welding, etc. The difference between three types of piece ball valves The working principle of the sanitary one-piece ball valve, that is, the Cantonese ball valve, is to make the valve unblocked or blocked by rotating the valve. The ball valve is light and small in size. It can be made into a large diameter. It has reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. The appearance structure of the one-piece ball valve is like a straight pipe. One end of the valve body is a step. The sealing ring, sphere, and seal are installed, and then tightened with a cap to form. Due to the special structure, the flow rate is limited by the diameter. For example, the inner hole of the DN50 thread mouth is 57. The connection is very simple, that is, the internal thread connection. It is used for very common water, oil and other pipelines and is widely used in various industries.
The sanitary two-piece ball valve and the gate valve are valves of the same type. The difference is that its closing piece is a sphere, and the sphere rotates around the center line of the valve body to achieve a valve that is opened and closed. The ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. The appearance structure of the two-piece ball valve is composed of two pieces, and the valve body is two parts. The flow rate is no longer limited by the diameter, but it is still fixed at one end and assembled with threads at the other end. The connection method is mainly internal thread connection. Mainly used for the processing and manufacturing of industrial fluids. The biggest difference between the two and the one-piece ball valve is the valve body.
The valve body of the sanitary three-piece ball valve consists of three parts, including the valve core position and the two end positions. It can be completely disassembled and cleaned. The full flow of the diameter is available, and the connection methods are diversified, including welding, quick-installation, and internal thread. The welded type can be polished for sanitary internal and external diameters, and can also be connected with quick installation. It is used in food, pharmaceuticals, electronics, vacuum, etc.
