Shell is collectively constituted, left valve barrel, sealing ring, downstream valve seat, spheroid, upstream valve seat, butterfly spring, right valve barrel are sequentially connected, ball
Body, valve rod, filler, gland, hold-down grid, valve rod adapter sleeve are sequentially connected, and are inside sleeved in spheroid hole, and are welded with spheroid
Connect, labyrinth valve element first, labyrinth valve element second, labyrinth valve element third is parallel is placed in inner sleeve, tilted with inner sleeve axis it is angled, with
Inner sleeve is welded, and every piece of labyrinth valve element plane has one to be diametrically distributed five through holes as regulation discharge orifice, the tune of labyrinth valve element first 6
Diameter where throttle orifice center is into upright position, and diameter where the regulation discharge orifice of three pieces of labyrinth valve elements is mutually hexagonal angle, every piece
Valve element five regulation the diameter of flowing hole in labyrinth are ascending successively, and the regulation discharge orifice of labyrinth valve element second is more corresponding than labyrinth valve element first
The diameter of regulation discharge orifice is big, and the diameter of the regulation discharge orifice more corresponding than labyrinth valve element second of labyrinth valve element third is big, and discharge orifice is adjusted after welding
Axis and spheroid axially bored line keeping parallelism, while exchange throttling road hole and carry out stiff dough processing, strengthen its service life.
The beneficial effects of the utility model are, as a result of labyrinth valve element, can function well as reduce velocity of medium and
The effect of rate-of flow is adjusted, simple in construction, dependable performance, cost are low, easy processing, and exchange throttle orifice and carried out at stiff dough
Reason, strengthens its service life.
