Abstract
The utility model relates to a complete jointing forged steel ball valve, wherein a welded joint is respectively adopted between a valve and an up axis sleeve and between the valve and a valve cover. Therefore, any possible leakage during the connection of bolts and backing pieces are totally avoided, and at the same time, as no bolt connection is adopted at the middle, the outer radial size of the entire valve is clearly reduced, thus the material cost of the valve and the valve cover is reduced, and the materials such as bolts, nuts, backing pieces, and O-shaped seal rings used in the middle is saved.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of All-welded Forged Steel Ball Valve.
Background technique
The tradition forging steel ball valve adopts three sides dress forged steel structure, middle part and axle sleeve and being connected of valve body to adopt bolt to connect.Use the sealing of fluororubber O-type ring and Graphite pad, because the problem of sealing is often brought leakage problem as Upper shaft sleeve and valve seal and valve body and valve gap.
Summary of the invention
The utility model provides a kind of all-welded ball valve, contingent any leaking outside when having avoided bolt, pad connection fully.
The technical solution of the utility model is as follows: a kind of All-welded Forged Steel Ball Valve comprises valve body and valve gap, be provided with spheroid in the valve body, the two ends up and down of spheroid are respectively equipped with liner plate, be connected with valve rod on the spheroid, valve rod passes the gland that is located at the valve body upper end, is provided with Upper shaft sleeve between valve rod and valve body, wherein, between valve body and the Upper shaft sleeve, adopt between valve body and the valve gap to be welded to connect.
Contingent any leaking outside when not only having avoided bolt, pad connection fully by welding manner.Simultaneously,, the outside dimension of whole valve body is had significantly reduce, reduced the cost of material of valve body, valve gap and saved materials such as the used bolt in middle part, nut, pad, O RunddichtringO because the middle part non-bolt connects.
Description of drawings
Fig. 1 is the structural representation of full welding forged steel valve.
Among the figure, 1. valve body 2. valve gaps 3. helical springs 4. are valve seat bearing ring 5.O RunddichtringO 6. seal rings, and 7. 13. glands, 14. Upper shaft sleeves, 15. liner plates, 16. graphite braiding packing is coiled in 12. connections of spheroid 8. sliding bearings 9. liner plates 10. liner plate pins 11. valve rods
Embodiment
As shown in Figure 1, All-welded Forged Steel Ball Valve comprises valve body 1 and valve gap 2, be provided with spheroid 7 in the valve body 1, the two ends up and down of spheroid 7 are respectively equipped with liner plate 9,15, be connected with valve rod 11 on the spheroid 7, valve rod 11 passes the gland 13 that is located at valve body 1 upper end, is provided with Upper shaft sleeve 14 between valve rod 11 and valve body 1, wherein, adopt between valve body 1 and the Upper shaft sleeve 14 and between valve body 1 and the valve gap 2 and be welded to connect.Contingent any leaking outside when so not only having avoided bolt, pad connection fully.Simultaneously,, the outside dimension of whole valve body is had significantly reduce, reduced the cost of material of valve body, valve gap and saved materials such as the used bolt in middle part, nut, pad, O RunddichtringO because the middle part non-bolt connects.
