Product introduction

Shanghai Zhen Guan mechanical and Electrical Equipment Co., Ltd. imports Germany in principle. HAWE Harvey The whole series of products, Harvey one-way valve, reversing valve, stop valve, plunger pump, gear pump and other products, Harvey has its own characteristics, some products are more difficult to replace, high pressure and high temperature resistance.
  Harvey check valve
Harvey check valve It includes ordinary one-way valve and hydraulic check valve, and the general one-way valve of one-way valve is not specified. The one-way valve is a relatively simple component in the hydraulic system, but any system is indispensable. Its function in the hydraulic system can be described as "simple and crude".
 
The principle of the imported HAWE Harvey one-way valve is to make the oil forward and reverse cut-off (similar to the diode in the circuit). According to the spool structure, one-way valves can be divided into two types: ball valves and cone valves. The ball valve is simple in structure and easy to manufacture, but it is not oriented. Its sealing performance is poor and seldom used. The cone valve technology is strict, but its sealing performance is good. The one-way valve used in engineering is mostly cone valve structure. According to the same direction of inlet and outlet, there are two kinds of straight through and right angle structure.
 
Usually, the check valves require small opening pressure, good reverse sealing, small forward flow resistance and sensitive action. The one-way valve shall be used in cases where the oil flow is not allowed: for the outlet of the hydraulic pump, preventing the damage of the hydraulic pump due to the high pressure of the system causing the oil to flow backward.
 
In the field of hydraulics, Shanghai is still responsible for its own reputation, reputation and reputation. It is the principle of word-of-mouth and customer first. If there is a question of product quality after sale, we are also the first time to help customers solve problems and help every customer to solve urgent problems.
