Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, a kind of dress formula two-way hard seal eccentric ball valve of going up, comprise upper valve rod 1, the lower valve rod 9 coaxial with upper valve rod, valve body 4, the valve gap 8 of fixedlying connected with valve body 4, Pian Xin left valve seat 2 laterally, left side spherical crown 3, spheroid 5, right spherical crown 6, Pian Xin right valve seat 7 to the inside, lower valve rod 9 is fixedly mounted on the valve body 4, upper valve rod 1 is installed in rotation on the valve gap 8 and with valve gap 8 and is sealed and matched, spheroid 5 is arranged between upper valve rod 1 and the lower valve rod 9 and with upper valve rod 1 fixedlys connected, left side valve seat 2 and right valve seat 7 are installed on two side runners of valve body 4, left side valve seat 2 can be fixedly mounted on the left side runner of valve body 4 by left pressure ring 12, and right valve seat 7 can be fixedly mounted on the right side runner of valve body 4 by right pressure ring 13.During the seal leakage of two-way hard seal eccentric ball valve, only need the gland nut of left pressure ring 12, right pressure ring 13 is twisted, adjust or change the left valve seat 2 in back, right valve seat 7 is still available, avoided valve seal to lose efficacy after, whole drawback of scrapping.The both sides of spheroid 5 are respectively equipped with eccentric laterally left billiard table 10 and eccentric to the inside right billiard table 11, best eccentric manner of the present utility model is that eccentric laterally left billiard table 10 and eccentric to the inside right billiard table 11 throw of eccentric equate, be that A1 equates (as shown in Figure 5) with A2, the Pian Xin left valve seat 2 and right valve seat 7 throw of eccentric equal (promptly the eccentric downwards distances of left valve seat 2 as shown in Figure 2 equate with the distance that right valve seat 7 makes progress off-centre) of off-centre laterally to the inside.Above-mentioned keying of going up dress formula two-way hard seal eccentric ball valve is according to the tight principle of off-centre-Qi, rely on eccentric left spherical crown 3, right spherical crown 6 to realize with left valve seat 2, the 7 sealing surface clutches of right valve seat, because spherical crown center and center shaft axis have certain spacing that departs from, so be called eccentric ball valve.The existence of this spacing makes valve when closing, spinning ball 5, and spherical crown and valve seat are crowded more tight more, guarantee that valve has excellent sealing performance.In opening-closing process, spheroid 5 angle of swing are not more than 90 °, so the keying of two-way hard seal eccentric ball valve is rapidly.Be provided with hollow duct 15 between left side billiard table 10 and the right billiard table 11, left side spherical crown 3 is fixedly mounted on the left billiard table 10, right spherical crown 6 is fixedly mounted on the right billiard table 11, as concrete application mode of the present utility model, described left billiard table 10 is provided
