Abstract
The utility model relates to a high pressure water gap seal rotary spray head which comprises a shell body, a rotary shaft sheathed inside the shell body, a shaft core sheathed inside the rotary shaft and fixedly connected with the shell body, a bearing and a sealing ring which are arranged on the outer layer of the rotary shaft and positioned between the rotary shaft and the shell body, a high pressure water spray nozzle arranged at the back end part of the rotary shaft, a low pressure water return outlet arranged at the front end part of the rotary shaft, and a high pressure water joint, wherein, the rotary shaft and the center of the shaft core are provided with radial through holes for high pressure water to flow across, and gaps for preventing water from leaking are arranged between the rotary shaft and the shaft core. When the utility model works, thrust force generated by the ejection of high pressure water drives the rotary shaft to rotate relatively to the shaft core, and jet ejected through the spray nozzle forms a rotary jet. The utility model extends the useful service life of sealing.
Description
The utility model relates to sprinkler head, particularly a kind of water under high pressure clearance seal rotary nozzle that is used to clean.
Existing rotatory sealing is generally seal with O ring or packing seal structure, because the poor lubricity of water, viscosity is low, along with constantly increasing of working pressure and improving constantly of rotary speed, the friction meeting of rotary seal face sharply strengthens, and the sealing rapid wear obviously speeds, and has shortened Acceptable life.
The purpose of this utility model provides a kind of new water under high pressure clearance seal rotary nozzle, and the thrust that it can make high-pressure water jet produce makes rotating shaft with respect to the rotation of axle core, and the jet that penetrates through nozzle forms rotating jet.
A kind of water under high pressure clearance seal rotary nozzle described in the utility model comprises housing, also be included in the rotating shaft of suit in the housing, axle core suit, that fixedly connected with housing in rotating shaft, at rotating shaft outer bearing and sealing ring that install and between rotating shaft and housing, the hydraulic spray of installing in the rearward end of rotating shaft, the low pressure backwater outlet that is provided with at the leading section of rotating shaft, and with the leading section and the interconnected water under high pressure joint of housing of rotating shaft; The center of described rotating shaft and axle core is provided with the radial direction through hole of the water under high pressure of can flowing through, and is provided with the gap that damping water leaks between rotating shaft and the axle core.
During the utility model work, water under high pressure is entered by the import department of water under high pressure joint, and by axle core and rotating shaft through hole, finally by the nozzle ejection, water under high pressure pressure discharges, and forms the straight jet of spraying forward.Draw by the outlet of low pressure backwater by the backwater that seal clearance leaks out.Because nozzle and rotating shaft core biasing, the thrust that high-pressure water jet produced make rotating shaft with respect to the rotation of axle core, the jet that penetrates through nozzle forms rotating jet.
The utility model does not contact with the axle core at the rotary course shaft owing to have the gap between the kinematic pair, so just can not produce friction, does not just have the rapid wear problem of consumable accessory yet, thereby has prolonged the Acceptable life of sealing.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is a kind of structural representation of water under high pressure clearance seal rotary nozzle.
Referring to accompanying drawing, a kind of water under high pressure clearance seal rotary nozzle comprises housing 1, the rotating shaft 2 of suit in housing 1, axle core 3 suit, that fixedly connected with housing 1 in rotating shaft 2, at rotating shaft 2 outer bearing 4 and sealing rings 5 that install and between rotating shaft 2 and housing 1, the hydraulic spray of installing in the rearward end of rotating shaft 26, the low pressure backwater outlet 7 that is provided with at the leading section of rotating shaft 2, and with the leading section and the housing 1 interconnected water under high pressure joint 8 of rotating shaft 2.
The center of rotating shaft 2 and axle core 3 is provided with the radial direction through hole 9 of the water under high pressure of can flowing through.Water under high pressure enters from the import department of water under high pressure joint 8, and the radial direction through hole 9 of flow through rotating shaft 2 and axle core 3 is penetrated by hydraulic spray 6.
Be provided with the gap 17 that damping water leaks between rotating shaft 2 and the axle core 3, to form the water under high pressure clearance seal.
The rearward end of rotating shaft 2 is positioned at hydraulic spray 6 installation places rotating disk 11 is housed, and fixedly connected by pin 12.Sealing ring 15 is housed between the rearward end of rotating disk 11 and rotating shaft 2.
Two hydraulic sprays 6 are installed on the rotating disk 11 shown in the figure, three or more hydraulic spray 6 also can be installed, the jet that penetrates through hydraulic spray 6 promptly forms rotating jet.The angle of jet can realize by changing nozzle angle, and the quantity of nozzle then decides with the flow size of water under high pressure input according to actual needs.The speed of jet rotation depends on the size of moment of torsion, and promptly this three is proportional with offset or dish, pressure, flow, also can change existing rotating speed by regulating resistance by damping unit is set.
Bearing 4 and sealing ring 5 are provided with two groups, are installed in rotating shaft 2 outer field front and back two sides respectively.One group of bearing 41 of installed in front and sealing ring 51 in rotating shaft 2; At the rear side of rotating shaft 2 another group bearing 42 and sealing ring 52 is installed, and packing ring 13 and back-up ring 14 are installed, this group bearing 42 is provided with two, is the parallel arranged shape.
Sheath 10 is equipped with in the low pressure backwater exit that is positioned at of housing 1.Between axle core 3 and the water under high pressure joint 8 sealing ring 16 is housed.At work, the backwater that is leaked out by seal clearance is drawn by the outlet of low pressure backwater.
The utility model has been realized reasonable leakage, promptly under the prerequisite that does not influence final jeting effect, allow water under high pressure rotatory sealing that a rational leakage rate is arranged, but leakage rate there is a control range, because excessive leakage rate will cause the loss of energy, reduce operating efficiency, therefore, leakage rate must be less than 10% of jet flow, otherwise sealing will be judged to inefficacy.
