Preferably, the outer wall of the flaring connecting portion is taper surface, the busbar and axis of the outer wall of the flaring connecting portion The angle of line is 40 degree.
Preferably, second seal groove is annular groove, the cross sectional shape of second seal groove is rectangle, described The corner of two seal groove inner rings is equipped with the first arc transition.
Preferably, first seal groove is annular groove, one end of a seal groove is equipped with cascaded surface, described first The other end of seal groove is equipped with the first taper surface, and the angle between the busbar and axis of first taper surface is 60 degree, described The junction of cascaded surface, the first taper surface and the first seal groove is equipped with the second arc transition.
Preferably, the end of first connector is equipped with inlet, the shape of the inlet is truncated cone-shaped, described The busbar of inlet and the angle of axis are 30 degree.
Preferably, the axis of the mainstream channel and the axis of the first connector, the second connector coincide.
The beneficial effects of the utility model:The utility model by pipe fitting body, the first connector, flaring connecting portion, The cooperation of hex nut block, the second connector, the first seal groove and the second seal groove etc., the end of connector are equipped with inlet just In installation, it is flared on connecting portion and closure gasket groove, the top setting sealing taper surface of nut block is set, sealing effect is good, reduces stream Body leaks, dependable performance.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
