Micro-liquid polyurethane micro-device back to the throttle

The utility model relates to a miniature backflow throttle valve in a miniature polyurethane mixing device with convenient adjustment of hydraulic pressure, constant setting pressure and little clogging, which comprises a valve body, a valve core, a valve seat, an adjusting locking device, The valve seat is provided with an inverted cone matching structure, that is, the top portion of the valve core is a cone-shaped body, the inverted cone body is opposite to the conical horn cone angle on the valve seat, and the conical horn on the valve seat is discharged toward the cavity in the valve body The cavity side, the end of the spool inverted cone body is located in the valve body inlet, the inverted cone on the spool and the horn bottom hole relative position to form a coaxial annular orifice, the spool cone valve seat Cone angle between the two cone angle and the cone, so that a certain viscosity of the liquid through the orifice after the orifice, the pressure drop stability, rapid flow through the smooth, completely solve the plug problem; flow generated from the heart Role, not only the throttle before and after the constant pressure, the adjustment is also very convenient.
