(1) disassembly of tubular check valve

 

 

 

The structure of the tubular check valve is very simple, it only has the valve body, the valve core, the seat (domestic I type check valve has no seat, the valve body is also used as the seat) and several parts such as spring, Figure 2-5(a) ~ (C) are respectively the appearance, structure, disassembly and assembly examples of the tubular through check valve. Domestic type I, A type of check valve, Japan oil research company CRG type check valve, German Rexroth company S type check valve and THE United States Weig company DT type check valve are similar to this structure. -china manifold block manufacturers

 

 

 

The disassembly method of straight-through check valve is shown in Figure 2-5(c) : Remove the clamp spring 5, and then take out the parts such as pad, spring, spool and so on from the valve body 1 in sequence. The sequence of installation and disassembly is reversed. -china manifold block manufacturers
