Product modeling and design ability has been greatly improved, but after the completion of product design, before mass production, we must make samples to express the design idea, quickly obtain the feedback information of product design, and evaluate and demonstrate the feasibility of product design. In today's increasingly fierce market competition, time is benefit. In order to improve the competitiveness of the product market, the whole process from product development to mass production is urgently required to reduce the cost and improve the speed. The emergence of rapid prototyping technology provides an effective way to solve this problem, and has attracted much attention at home and abroad Ningbo Rongna Technology Co.,Ltd , https://www.prototyping-products.com
Check valve knowledge
Check valve, also known as check valve or check valve. Used in hydraulic system to prevent reverse flow of oil. Check valves are straight-through and right-angle two. Straight through check valve with threaded connection installed in the pipeline. Right angle check valve threaded connections, plate connections and flange connections in three forms. Hydraulic check valve, also known as the lock valve or pressure control valve, which is the same with the one-way valve to prevent reverse flow of oil. However, in the hydraulic circuit, when the reverse flow of the oil flow is needed, the oil pressure can be controlled and the check valve can be opened so that the oil flow can flow in both directions. Hydraulic check valve with tapered spool, so good sealing performance. When required to close the oil circuit, this valve can be used as a one-way locking oil pressure from the packing effect. Leakage check valve control oil leak-type and leakage of two types. In the reverse flow of oil flow without back pressure in the internal discharge available; otherwise need to leak, in order to reduce the control of oil pressure.
