(3) beneficial effect
The utility model makes valve seat to combine closely with spheroid by the setting of all parts, has strengthened the effect of sealing, thereby has increased the sealing reliability of integrated ball valve, has extended the working life of valve.
Description of drawings
Fig. 1 is the longitudinal section according to a kind of embodiment's of the utility model integrated ball valve;
Fig. 2 is the plan view of integrated ball valve shown in Figure 1;
Fig. 3 is the enlarged diagram of B part in integrated ball valve shown in Figure 1.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the longitudinal section according to a kind of embodiment's of the utility model integrated ball valve; Fig. 2 is the plan view of integrated ball valve shown in Figure 1; Fig. 3 is the enlarged diagram of B part in integrated ball valve shown in Figure 1.Described integrated ball valve comprises: valve body 1, valve rod 12 and spheroid 3, end face near described valve rod 12 on described spheroid 3 is provided with a groove, described valve rod 12 lower ends are fixed in described groove, described integrated ball valve also comprises: valve seat fixture 15, described valve body 1 is provided with the valve seat 2 of being made by elastic material, described valve seat 2 is fixed in described valve body 1 by described valve seat fixture 15, by spheroid 3 and coordinating of valve seat 2 reaching good sealing effect;
Preferably, the lower end of described valve rod 12 is convex shoulder structure, but both anticreeps has guaranteed again upper sealability;
For enhanced leaktightness, preferably, the upper surface of described convex shoulder structure is provided with from bottom to up successively: thrust washer 13, the first lining 4, the first packing ring, the first packing ring 5, pad, the second packing ring 6, the second packing ring, the second lining 7 and filler flange 9, described filler flange 9 is installed on described valve body 1 and compresses described the second lining 7, to form upper sealing effect;
In order to strengthen the sealing between valve body 1 and valve seat 2, preferably, be provided with sealing gasket 16 between described valve body 1 and valve seat fixture 15;
Described integrated ball valve also comprises: the valve rod driver element that is used for driving described valve rod 12, described valve rod driver element further comprises: the handle 8 that is connected with described valve rod 12, described valve rod driver element also comprises: stop baffle plate 19 and jam plate 17, described handle 8, jam plate 17 and stop baffle plate 19 set gradually from the top down, and be connected with valve rod 12 is coaxial by nut 10, described jam plate 17 is that 90 ° of switch positioning meanss have indicative function, can prevent misoperation;
