The inner conical surface of valve hole described in the utility model becomes 25-35 degree angle with the axle center of valve hole, the male cone (strobilus masculinus) of poppet valve core becomes 25-35 degree angle with the axle center of poppet valve core.
The endoporus of pressure measuring tie-in body one end described in the utility model is counter sink, and the end face of cone valve one end offers second seal groove, is provided with the 2nd O shape circle in the sealing groove, and the 2nd O shape circle is close to the end face of counter sink.
The intermediate section of cone valve described in the utility model is provided with shaft shoulder portion, and the valve body screw thread is arranged in the shaft shoulder portion.
The inner conical surface of valve hole described in the utility model becomes 30 degree angles with the axle center of valve hole, the male cone (strobilus masculinus) of poppet valve core becomes 30 degree angles with the axle center of poppet valve core.
The dual-side of the shaft shoulder described in the utility model portion is the hypotenuse shape.
The utility model compared with prior art has the following advantages and effect:
When 1, installing, can successively spring and poppet valve core be put into the pressure measuring tie-in body, cone valve is screwed into the pressure measuring tie-in body by screw thread, and is not only easy to assembly, also reduced the technological requirement of component;
2, because employing is threaded, make cone valve to dismantle easily, change component such as poppet valve core;
3, adopting 25-35 ° of conical surface seal to cooperate between poppet valve core and the cone valve can make pressure measuring tie-in open or close fast;
4, the 25-35 of a poppet valve core ° male cone (strobilus masculinus) is provided with O shape circle, this elastic sealing structure, and its centering is effective, effectively improves the reliability of sealing;
5, the utility model structure can be used for the online pressure measurement of 63Mpa hydraulic system.
