Venturi application is introduced
Venturi tube is developed according to the venturi effect a throttling flow sensor, is a standard throttling device. Venturi tube structure is divided into standard venturi tube and general venturi tube. Venturi pipe flow water device is throttling throat, differential pressure gauge and pressure guide tube of three parts.
Standard (classic) venturi tube according to its different manufacturing methods are divided into a rough casting shrinkage standard venturi, with standard venturi for machining contraction, with thick plate welding contraction of standard venturi.
Venturi tube is applied in various industries all kinds of medium flow measurement, control and regulation; It has the characteristics of small pressure loss and long life. Venturi tube, also known as standard venturi tube, low pressure loss venturi tube, it retains valuable the basic characteristic of the venturi tube, the entrance to the cylinder length, and contraction Angle and diffusion has the change, the entire unit is valuable venturi tube shortened.
Standard venturi tube is one of the throttle device, it with differential pressure instrument, used to measure stable single-phase fluid in a closed pipe (volume flow of liquid, gas or steam). Due to its simple structure, reliable operation, has been widely used in chemical, petroleum, light industry, medicine, chemical fertilizer, metallurgical industry, etc.
Venturi tube standard design and manufacture according to GB/T2624-2006, according to GB JJG640-94 rolls. Gm series of venturi flow sensor in addition to the inherited standard venturi tube with high accuracy, good repeatability, small pressure loss, the former short straight pipe, etc, also have their own device is small, prevent the advantages. Can be used for the two to flow, miscible flow, low flow velocity, large diameter, special-shaped pipe and other complex flow measurement of the problem. Also has a wide application in the field of industrial and agricultural production, especially for muddy water pipeline, does not cause siltation, smooth flow smoothly, according to the principle of type selection of the throttle device, it is the first selection of muddy water channel flow device.
