This cone valve sealing pressure measuring tie-in, comprise adapter body, valve body, spool, dust cap, dustproof pin, needle for measuring blood pressue, spring, O type circle, wherein adapter body inner chamber is step cylindrical cavity, valve body is placed in the cylindrical cavity of topping bar, body cavity and the intercommunication of adapter body inner chamber, spool is placed in body cavity, dustproof pin or needle for measuring blood pressue are placed on valve body part, dust cap is by the dustproof pin in top under screw thread and adapter body turn or needle for measuring blood pressue, it is coordinated with spool, be characterized in that the spring supporting of spool lower end in being placed in step cylindrical cavity coordinates, spool is slided up and down in valve body, spool is provided with the groove of male cone (strobilus masculinus) and two holes that intersect vertically and O type circle, the male cone (strobilus masculinus) of spool matches with the inner conical surface of valve body, the cylndrical surface that valve body is provided with O type circle and back-up ring and dustproof pin or needle for measuring blood pressue is sealed and matched, its outside thread root is provided with O type circle and adapter body is sealed and matched, adapter body is provided with O type circle and dust cap lower edge is sealed and matched, be provided with seal ring and the external oil collecting mouth of pipe is sealed and matched.
The utility model compared with prior art, has following beneficial effect:
Under spring pressure effect, the laminating of the conical surface on spool and the conical surface on valve body realizes rigid seal, spool and on O type circle and the realization of the macropore in valve body elastic packing radially, from face, formed double sealing structure, prevent seepage.
Sealing between valve body and fittings body is placed in to the port of fittings body internal thread, realizes cone mouth elastic packing, not only easy to assembly, also reduced the processing technology requirement of part.
The utility model is not only for hydraulic system pressure on-line measurement, and can be used for the online pressure measurement of pneumatic system.
The utility model can be used for the online pressure measurement of 63MPa high-pressure hydraulic.
