Butterfly valve is a disc type open and close reciprocating rotary 90 ° Left and right to open, close or regulate the flow of a medium valve The door. Butterfly valve is not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving torque […]
The double eccentric butterfly valve is also called high-performance butterfly valve, which is mainly used for drainage of water works, power plants, steel smelting, chemical industry, water source spring engineering, environmental facilities construction and other systems, especially for waterway pipeline, as regulation and closure equipment. Compared with the center line butterfly valve, the double eccentric […]
Advantages and disadvantages of hydraulic press (1) Advantages For the hollow structure with variable cross-section, the traditional manufacturing process is stamping two half pieces first, and then welding them as a whole, while hydroforming can form the hollow structure with variable cross-section at one time. Compared with stamping and welding process, hydroforming technology has the […]
Key points of selection of common hydraulic valves The selection of proper hydraulic valve is an important condition to make the design of hydraulic system reasonable, the technical and economic performance excellent, the installation and maintenance simple, and to ensure the normal operation of the system. Because the selection of hydraulic valve is very important […]
What should be paid attention to when welding lifting rings？ Welding rings in production, its welding is a very important operation, is a test of human technology process. Matters needing attention in the welding of welding rings: 1. The welded structure can be annealed at a temperature of less than 600 ℃ for stress relief […]
Common materials of rings and riggings Based on the proper consideration of the use of rings, of course, it is better to choose high quality materials. Therefore, both manufacturers and users attach great importance to this issue. Kosobi is Professional manufacturers, a variety of non-standard specifications can produce, long screw use It does not affect […]
Classification of hydraulic valves According to different classification methods, hydraulic valves are divided into many kinds： 1、According to the control method: manual, electric control, hydraulic control, proportional 2、According to function: flow valve (throttle valve, speed control valve, shunt valve), pressure valve (relief valve, pressure reducing valve, sequence valve, unloading valve), directional valve (electromagnetic directional valve, […]
Application fields of stamping robot It is an effective method to use stamping robot instead of manual operation to form a fully automatic production line in stamping production. The overall design of the stamping robot should be considered comprehensively, so as to make it simple, compact, easy to operate, safe and reliable, convenient to install […]
Nondestructive testing of welded pipe fittings: NDT Definition of NDT for welded pipe fittings: NDT refers to a testing method for materials or workpieces that does not damage or affect their future performance or use. NDT can find defects in the interior and surface of materials or workpieces, measure the geometric features and dimensions of […]
Tube bending production process At present, there are basically two kinds of pipe bending production processes in China: The first type: small-diameter pipeline, the general outer diameter specification is ≤89mm, and cold bending is usually adopted, which is carried out by manual or numerical control pipe bending machine. After bending, annealing heat treatment is needed […]
