The deficiency existing for prior art, the purpose of this utility model is to provide a kind of ball valve valve gap that promotes sealing property of ball valves.
For achieving the above object, the utility model provides following technological scheme: a kind of ball valve valve gap, comprise end cap body, end cap body is provided with passage, passage comprises feed pathway and liquid outlet channel, on end cap body, be provided with near feed pathway end the first flange being connected with pipeline, on end cap body, be provided with near liquid outlet channel end the second flange being connected with valve body, on the end face of described end cap body near liquid outlet channel, convex with installing ring, between described installing ring and liquid outlet channel, be provided with die cavity, described die cavity is the assembly department of installing for ball core, described assembly department is the spill sphere suitable with ball core.
Described installing ring and end cap body are structure as a whole, and this installing ring includes end and outer side wall, and described end is rounding, and described outer side wall is rounding, and this rounding caves in to axis direction.
The circulation area of described passage expands gradually from feed pathway to liquid outlet channel direction.
Described end cap body sidewall is provided with some stiffening ribs, and described stiffening rib is located between the first flange and the second flange.
Described the first flange and the second flange are provided with some mounting holes, and described mounting hole is fixing threaded hole.
A kind of ball valve valve gap, comprise end cap body, end cap body is provided with passage, passage comprises feed pathway and liquid outlet channel, on end cap body, be provided with near feed pathway end the first flange being connected with pipeline, on end cap body, be provided with near liquid outlet channel end the second flange being connected with valve body, on the end face of described end cap body near liquid outlet channel, convex with installing ring, between described installing ring and liquid outlet channel, be provided with die cavity, described die cavity is the assembly department of installing for ball core, and described assembly department is the spill sphere suitable with ball core.By adopting technique scheme, end cap body coordinates with ball core by the seal ring of being located on assembly department, increase the sealing area of end cap body and ball core, and then improve its sealing, ensure that ball valve in use can not produce leakage, and the installing ring that protrudes from end cap body end face not only has the effect that increases sealing area, can also make ball core in use be difficult for producing vibration, be conducive to improve the stability of ball valve.
Brief description of the drawings
Fig. 1 is the sectional drawing of the utility model ball valve valve gap;
Fig. 2 is the A portion structure for amplifying schematic diagram of Fig. 1;
Fig. 3 is the structural representation of the utility model ball valve valve gap.
Reference character: 1, end cap body; 2, passage; 3, installing ring; 4, fixing threaded hole; 11, the first flange; 12, the second flange; 13, assembly department; 14, stiffening rib; 21, feed pathway; 22, liquid outlet channel; 31, end; 32, outer side wall.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model ball valve valve gap embodiment is described further.
A kind of ball valve valve gap, comprise end cap body 1, end cap body 1 is provided with passage 2, passage 2 comprises feed pathway 21 and liquid outlet channel 22, on end cap body 1, be provided with near feed pathway 21 ends the first flange 11 being connected with pipeline, on end cap body 1, be provided with near liquid outlet channel 22 ends the second flange 12 being connected with valve body, on the end face of described end cap body 1 near liquid outlet channel 22, convex with installing ring 3, between described installing ring 3 and liquid outlet channel 22, be provided with die cavity, described die cavity is the assembly department 13 of installing for ball core, described assembly department 13 is the spill sphere suitable with ball core.End cap body 1 is by coordinating ball core is arranged in valve body with being connected of valve body, the assembly department 13 of end cap body 1 is the spill sphere suitable with ball core, make to be located at and when seal ring on assembly department 13 coordinates with ball core, increased the sealing area of end cap body 1 with ball core, thereby improve its sealing, ensure that ball valve in use can not produce leakage.And the installing ring 3 that protrudes from end cap body 1 end face not only has the effect that increases sealing area, also there is holder and hold up effect, play to hold in the palm buttressing ball core as palm, make ball core in use be difficult for producing vibration, be conducive to improve the stability of ball valve.
Described installing ring 3 is structure as a whole with end cap body 1, and this installing ring 3 includes end 31 and outer side wall 32, and described end 31 is rounding, and described outer side wall 32 is rounding, and this rounding caves in to axis direction.Installing ring 3 is structure as a whole and has strengthened join strength and end cap body 1 bulk strength of installing ring 3 with end cap body 1, has the advantages such as good seal performance, reliability are strong.The end 31 of installing ring 3 is rounding, avoids ball core to scratch ball wicking surface in the time rotating and reduces its sealing, also can avoid the end 31 of installing ring 3 to scratch seal ring, reduces sealing and the working life of seal ring.On end cap body 1, the outer side wall 32 of installing ring 3 is rounding, and therefore outer side wall 32 can be installed " O " shape seal ring, improves the sealing that the second flange 12 is connected with valve body.
The circulation area of described passage 2 expands gradually from feed pathway 21 to liquid outlet channel 22 directions.Change and adjusted the nowed forming of liquid medium in feed pathway 21, utilize the circulation area diffusion liquid medium expanding, the flow velocity of liquid medium is reduced, thereby obviously reduce the impact to ball core, reduce the injury to ball core, increase the impact resistance of ball valve.
Described end cap body 1 sidewall is provided with some stiffening ribs 14, and described stiffening rib 14 is located between the first flange 11 and the second flange 12.Stiffening rib 14 between the first flange 11 and the second flange 12 has strengthened join strength and the bulk strength of end cap body 1, has the advantages such as simple in structure, reliability is strong.
Described the first flange 11 and the second flange 12 are provided with some mounting holes, and described mounting hole is fixing threaded hole 4.Because end cap body 1 is " work " font, and two end flange are at a distance of nearer, therefore flange operating difficulties in the time being connected with pipeline and valve body with nut by bolt, the mounting hole of the first flange 11 and the second flange 12 is made as after fixing threaded hole 4, only need screw in bolt from the outside of end cap body 1 and just can conveniently realize flange connection, also there is the advantages such as simple in structure, reliability is strong.
