<p>Disclosed is a high pressure valve including a main valve assembly vertically inserted into a body block (10) from a flat top end of the body block (10) to be fixed to the body block (10), and a pilot valve assembly horizontally inserted into the body block (10) from a flat side end of the body block (10) to be fixed to the body block (10). The present invention relates to a pressure sensitive type of a high pressure valve which opens or closes a high pressure pipe through a fluid pressure control of a pilot valve. The high pressure value is designed in a structure where all components moves (are opened or closed) in an inserting direction of the components, and all bypass pipes are designed in a straight line type of a pipe extending in the opening or closing operation direction thereof. Thus, a complex bypass pipe may be formed without a casting process, and components, which had been only integrally formed in the related art because a heavy load is applied to the components, may be configured in an exploded assembling type. The present invention may construct a complex and delicate pressure fluid charging and discharging circuit even through an economical fabricating process, as the present invention has a simple sealing structure using a screw coupled assembly, an o-ring, and a sheet type packing. In addition, the reason for a failure may be easily found, and the maintenance may be simplified.</p> |
