Detailed description of the invention
As shown in Figures 1 to 5, this lift kink joint hydrant includes spiral cover valve 1, water exit elbow 3, interior pipe 6, outer tube 11 and outer tube gland 13.
Described spiral cover valve 1 includes rotating shaft 2 and the spiral cover being arranged on rotating shaft 2, is provided with the first sealing gasket 4 and the second sealing gasket 5 on described rotating shaft 2.Described spiral cover valve 1 is arranged on water exit elbow 3, and the rotating shaft 2 of spiral cover valve 1 connects at water exit elbow 3 internal thread, and spiral cover valve 1 can spiral or decline on water exit elbow 3.
Described water exit elbow 3 outlet outer wall is provided with thread 304, and thread 304 matches with detachable cap 305, and described detachable cap 305 is arranged on water pipe.
It is additionally provided with annular protrusion 301 at the place of being screwed of spiral cover valve 1 with water exit elbow 3, when hydrant goes out water state, annular protrusion 301 spiral cover valve 1 continuous under spinning force, it is possible to fit with the first sealing gasket 4 closely, play better seal effect, as shown in Figure 4.
As shown in Figure 6, water exit elbow 3 outlet being provided with thread 15, thread 15 matches with detachable cap 16.Described detachable cap 16 may be provided on water pipe.When needs farmland is watered, adopt the water pipe being provided with detachable cap 16 to be easily connected with this water exit elbow 3, eliminate a large amount of fixing water pipe, seal the trouble of water pipe head, saved a large amount of manpower and materials.
As shown in Figures 2 to 4, junction at interior pipe 6 with water exit elbow 3, water exit elbow 3 is additionally provided with the first draw-in groove 302 and the second draw-in groove 303, is provided with lock ring 14 at the first draw-in groove 302 place of described water exit elbow 3, and the height of described lock ring 14 is slightly above the degree of depth of the first draw-in groove 302.Being provided with interior pipe 6 at the second draw-in groove 303 place of described water exit elbow 3, interior pipe 6 extrudes lock ring 14 and brings it about deformation.So when being in out water state, owing to being subject to the effect of interior pipe 6 hydraulic pressure, the inwall of interior pipe 6 outer wall and water exit elbow 3 fits tightly, and is additionally provided with lock ring 14 in combination with place, better increases its sealing.Lock ring 14 can not only play sealing function, moreover it is possible to the position of the interior pipe of restriction and the lifting distance of spiral cover valve 1, as shown in Figures 2 to 4.Being again provided with annular protrusion on lock ring 14, when spiral cover valve 1 drops to certain distance, the second sealing gasket 5 being arranged on rotating shaft 2 contacts with lock ring 14, and deforms.Thus spiral cover valve 1 cannot continue backspin, limiting the lifting distance of spiral cover valve 1, this design also ensure that the sealing between spiral cover valve 1 and lock ring 14 equally, has saved water resource, and structural design is simple, practical.
In relying between water exit elbow 3 and interior pipe 6, pipe hydraulic pressure seals, by designing first draw-in groove the 302, second draw-in groove 303 and the method installing lock ring 14 auxiliary seal, wherein, water exit elbow 3 is connected with interior pipe 6, the rotation of be capable of between water exit elbow 3 and outer tube 11 360 degree, is conducive to water exit elbow 3 any adjustment in 360 degree of water outlet direction in irrigation process of hydrant.
The protrusion slide block 9 preventing interior pipe from skidding off outer tube it is provided with in said inner tube 6 bottom outside.
In order to carry out the fixing of interior pipe 6 and outer tube 11 relative position, outer tube 11 end is provided with tight lock part 12, described tight lock part 12 inwall is provided with groove, H-shaped sealing gasket 7 is installed between groove and interior pipe 6, described tight lock part 13 outer wall is provided with screw thread, outer tube gland 13 is threadeded with tight lock part 12, and the bolt being arranged on this place may be configured as plain bolt, carries out the spacing of outer tube gland.This place's bolt also can be further arranged to special bolt, specific purpose tool need to be adopted just to open, play antitheft effect.
Along with the continuous backspin of outer tube gland 13, outer tube gland 13 can be oppressed H-shaped sealing gasket 7 and be fitted with interior pipe 6, it is ensured that the sealing between interior pipe 6 and outer tube 11, also can carry out fixing of the interior pipe 6 relative position with outer tube 11 simultaneously.And H-shaped sealing gasket 7 can be fixed in the groove of tight lock part 12 by outer tube gland 13, the slide block 9 that protrudes of H-shaped sealing gasket 7 also internal pipe 6 plays spacing effect.
Described water exit elbow 3 is additionally provided with dead bolt 306, outer tube gland 13 matches with dead bolt 306 and is provided with snap close 131, when irrigating when watering, device damage is caused in order to avoid interior pipe rises under the active force of hydraulic pressure, this feature is set, it is only necessary to rotated to the snap close 131 of outer tube gland 13 by the dead bolt 306 of water exit elbow 3.When needs water irrigation, then dead bolt 306 is screwed out snap close 131.
Tight lock part 12 is additionally provided with screwed hole, when outer tube gland is screwed into certain position 13 times, it is not necessary to during backspin, bolt is installed between two lower edge baffle plates of outer tube gland 13, carries out the spacing of outer tube gland 13, as shown in Figure 1.
The other end of described outer tube 11 is provided with water inlet 8, and the junction of water inlet 8 with outer tube 11 is provided with annular lug, and the slide block 9 that protrudes of internal pipe 6 plays the effect of lower limit.
Working method, when being made without pouring farmland, this lift kink joint hydrant is in below ground, can be provided with protecting cover at hydrant top, this protecting cover can be provided with relevant lockset, play anti-theft function.
When needs carry out field irrigation, open protecting cover, first this lift kink joint hydrant is used for, by being arranged on tight lock part 12, the bolt taking-up that spacing outer tube gland 13 rotates, then upper rotation outer tube gland 13, the H-shaped sealing gasket 7 fitted tightly in interior pipe 6 is made to separate with interior pipe 6, then under the effect protruding slide block 9 on the inner tube 6, interior pipe 6 moves up along the chute 10 on outer tube 11, after arriving correct position, locking outer tube gland 13, and bolt at tight lock part 12, now start to rotate properly turning to of fixing water exit elbow 3 on the inner tube 6, rotate spiral cover valve 1 to the first sealing ring 4 to fit tightly with annular protrusion 301, water supply start.
After having watered field, when needing to close, rotate spiral cover valve 1 to the second sealing ring 5 to fit tightly with the annular protrusion on lock ring 14, then water exit elbow 3 direction is rotated to correct position, make its position not easily encountered, it is used for the bolt taking-up that spacing outer tube gland 13 rotates by being arranged on tight lock part 12, then upper rotation outer tube gland 13, the H-shaped sealing gasket fitted tightly in interior pipe 6 is made to separate with interior pipe 6, interior pipe 6 is pressed in outer tube 11, then locking outer tube gland 13, and bolt at tight lock part 12.
Finally cover protecting cover, lock lockset, complete whole circulation.
Except the technical characteristic described in description, it is the known technology of those skilled in the art.
