The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of easy to maintenance, improve valve seat and spheroid working life, improve the upper dress formula floating ball valve of ball valve sealing performance.
The technical solution of the utility model is achieved in that a kind of upper dress formula floating ball valve, it comprises valve body, valve gap, spheroid, valve rod, described spheroid is arranged in valve body, described valve gap is arranged on the valve body top, offer the passage of up/down perforation on described valve gap, described valve rod is fastened in passage, the bottom of described valve rod is connected with the spheroid top, described valve gap and valve body removably connect, be provided with the valve seat group between described spheroid and valve body, described valve seat group comprises metal seat valve and soft valve seat, described metal seat valve and valve body join, described soft valve seat and spheroid join, described stem lower portion fixed cover is provided with spring, described spring is between valve rod and spheroid.
Preferably, on described valve gap, the valve body upper-end surface offers the screw of mutual correspondence, in the screw of every pair of correspondence, is provided with screw.
Preferably, the upper end of described valve rod is through valve gap, and the upper end of described valve rod is provided with nut, is arranged with the dish spring on described valve rod, and described dish spring is between nut and valve gap.
Preferably, the inwall bottom of described valve gap arranges groove, and described stem lower portion outer wall is provided with a circle projection, and described projection is fastened in groove.
Preferably, described spring housing is located on the valve rod of projection below.
The beneficial effects of the utility model have following some:
One, be arranged to valve gap and valve body to removably connect, when the inner sealing damage parts of this ball valve, can can repair or replace part on pipeline directly by the valve gap dismounting be contained on valve body, guarantee the ball valve normal operation, saved the time, easy to maintenance;
Its two, the valve seat group comprises metal seat valve and soft valve seat, and metal seat valve and valve body join, soft valve seat and spheroid join, the setting of soft valve seat has reduced the wearing and tearing of spheroid and valve seat, has improved the working life of spheroid and soft valve seat;
Its three, the setting of spring, give between spheroid and soft valve seat pretightening force be provided, though make valve seat in the situation that wearing and tearing still with the spheroid close contact, still there is good sealability, guaranteed the good sealability of ball valve integral body.
The accompanying drawing explanation
