Abstract
The utility model provides a fixed ball valve, which comprises a valve body, a valve seat, a sealing ring, a ball body and a spring I, wherein the sealing ring is mounted in the valve seat; the spring I is mounted between the valve seat and the valve body; a scraper seat is additionally mounted below the valve seat and is in line contact with the ball body; a spring II is mounted between the back surface of the scraper seat and the valve seat; and an O-shaped ring is additionally mounted between the scraper seat and the valve seat. The fixed ball valve has the beneficial effects that the ball body is always in a clean state, the valve can be flexibly opened and closed and the service life is long.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of Fixed ball valve.
Background technique
Use the Fixed ball valve that uses in metallurgy industry breeze blowing system at present, valve seat is installed on the valve body, and seal ring is installed on the valve seat; Between the valve seat back side and valve body spring is housed, seal ring leans on the spring force effect to keep in touch with the sphere of spheroid all the time, after operation a period of time; Dust can be bonded on the spheroid; Cause valve jam phenomenon, seal ring is easy to wear, and working life is short.
Summary of the invention
When moving, existing Fixed ball valve is prone to jam in order to overcome, the deficiency that ring wear, working life lack, and the utility model provides a kind of Fixed ball valve.
It is a kind of Fixed ball valve that the utility model solves the technological scheme that its technical problem adopted; Comprise valve body, valve seat, seal ring, spheroid, spring I; Seal ring is contained in the valve seat, and spring I is housed between valve seat and valve body, and the valve seat below also is equipped with and is scraped tool rest; Scraping tool rest is that line contacts with spheroid, scrapes between the back side and the valve seat of tool rest spring II is housed.
Scrape O shape circle also is housed between tool rest and the valve seat.
The beneficial effect of the utility model is that spheroid is in clean conditions always, and valve opening and closing is flexible, long service life.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is embodiment's a tectonic maps.
Among the figure: 1. valve body; 2. spring I; 3. valve seat; 4. seal ring; 5.O shape circle; 6. spring II; 7. scrape tool rest; 8. spheroid.
Embodiment
As shown in Figure 1, a kind of Fixed ball valve comprises valve body 1, valve seat 3, seal ring 4, spheroid 8, spring I 2; Seal ring 4 is contained in the valve seat 3; 1 of valve seat 3 and valve body are equipped with spring I 2, and valve seat 3 belows also are equipped with and are scraped tool rest 7, scrape tool rest 7 and contact for line with spheroid 8; Scrape between the back side and the valve seat 3 of tool rest 7 spring II 6 is housed, make and scrape tool rest 7 and be close to spheroid 8 always.Scrape O shape circle 5 also is housed between tool rest 7 and the valve seat 3.Scrape the edge of a knife of tool rest 7 and in the valve opening and closing process, can remove the dirt on the spheroid 8, keep the clean and tidy of spheroid 8, in addition, scrape tool rest 7 and contact with the linearity of spheroid 8, played the effect of auxiliary seal, valve seal is reliable, long service life.
