Abstract
The utility model discloses an intermittent water supply type rotary joint. The intermittent water supply type rotary joint comprises a shell, a sealing ring, a hollow shaft, a rolling bearing and a check ring, wherein a water inflow hole is formed in the side face of the upper end of the shell, the sealing ring with a hole is arranged between the upper end of the hollow shaft and the shell, the hole of the sealing ring corresponds to the water inflow hole, the sealing ring is fixed to an inner cavity in the upper end of the shell, a water inflow tank is formed in the portion, as high as the water inflow hole, of the upper end of the hollow shaft, and communicated with a water outflow hole in the lower end of the hollow shaft, the hollow shaft is connected to the shell though the rolling bearing and the check ring, the shell is fixed, and the hollow shaft can rotate when driven by external force. Because the structure is adopted for the intermittent water supply type rotary joint, the intermittent water supply type rotary joint is applicable to workplaces needing rotary and intermittent liquid supply or gas supply.
Description
Technical field
The utility model relates to a kind of intermittent water application device, particularly a kind of intermittent water application formula swivel joint.
Background technique
At present, the feed flow of existing rotary joint or plenum system are all the forms of supplying with continuously, after joint is opened, and will be to the follow-up pipeline of joint liquid without interruption or gas.This rotary joint is for requiring the occasion of rotation and interruption feed flow or air feed by inapplicable, therefore there is the limited defect of application area, as the water supply form of the Rotary Water besom of environmental sanitation sweeper, adopt existing continuous water supply formula swivel joint just cannot meet usage requirement.
Summary of the invention
The purpose of this utility model is the problem that solves above-mentioned existence, and a kind of intermittent water application formula swivel joint applicable to rotation and interruption feed flow or air feed occasion is provided.
For realizing above object, a kind of intermittent water application formula of the utility model swivel joint comprises housing, seal ring, hollow shaft, rolling bearing and back-up ring; Described housing upper side is provided with a water inlet; Between described hollow shaft upper end and housing, be provided with seal ring with holes, sealing circle hole is corresponding with water inlet, sealing circle is fixed on the inner chamber of housing upper end, and hollow shaft upper end and water inlet equal-height position are provided with intake chamber, the osculum UNICOM of this intake chamber and hollow shaft lower end; Described hollow shaft is bound up on housing by rolling bearing and back-up ring; Housing maintains static, and hollow shaft can rotation under external force drives.
Described intake chamber substantially horizontal is 50 ° of-70 ° of radians from the shared arc length of origin-to-destination.
Described intake chamber is shaped as horizontal strip keyway shape.
The hollow shaft of above-mentioned intermittent water application formula swivel joint drives rotation by external force, and when the intake chamber of hollow shaft upper end aligns with the water inlet on housing, water enters the intake chamber of hollow shaft upper end by the water inlet of housing, then discharges by the osculum of hollow shaft lower end; When the intake chamber of hollow shaft upper end leaves the water inlet on housing, the sealed circle in water inlet on housing stops, water cannot enter hollow shaft, and now, the osculum of hollow shaft lower end not there are flowing out; At hollow shaft, often rotating a circle just to have in the fan-shaped arc length of 50 ° of-70 ° of radian scopes has water supply, remains in 310 ° of-290 ° of radian arc length and stops supplying water, thereby realize the object of rotating intermittent water application.
By repetition test, the environmental sanitation sweeper of above-mentioned intermittent water application formula swivel joint is housed, the water supply form of its Rotary Water besom adopts intermittent water application mode, simple in structure, easy to use, can greatly improve water spray control accuracy and wash and sweep effect.
Accompanying drawing explanation
Fig. 1 is that a kind of intermittent water application formula of the utility model swivel joint master looks schematic diagram.
Fig. 2 is a kind of intermittent water application formula of the utility model swivel joint schematic top plan view.
Fig. 3 is that a kind of intermittent water application formula swivel joint A shown in Fig. 1 is to schematic diagram.
Reference character: housing 1, water inlet 1-1, seal ring 2, hollow shaft 3, intake chamber 3-1, osculum 3-2, rolling bearing 4 and back-up ring 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of intermittent water application formula of the utility model swivel joint is described in further detail.
Shown in Fig. 1-Fig. 3, a kind of intermittent water application formula of the utility model swivel joint comprises housing 1, seal ring 2, hollow shaft 3, rolling bearing 4 and back-up ring 5; Described housing 1 upper side is provided with a circular water inlet 1-1; Between described hollow shaft 3 upper ends and housing 1, be provided with the seal ring 2 with circular hole, sealing circle hole is corresponding with circular water inlet 1-1, sealing circle is fixed on housing 1 upper end inner chamber, hollow shaft 3 upper ends and circular water inlet 1-1 equal-height position are provided with the intake chamber 3-1 of horizontal strip keyway shape, intake chamber 3-1 substantially horizontal is 60 ° of radians from the shared arc length of origin-to-destination, the osculum 3-2 UNICOM of this intake chamber 3-1 and hollow shaft 3 lower ends; Described hollow shaft 3 is bound up on housing 1 by rolling bearing 4 and back-up ring 5; Housing 1 maintains static, and hollow shaft 3 can rotation under external force drives.
During work, when the intake chamber 3-1 of hollow shaft 3 upper ends is when circular water inlet 1-1 on housing 1 aligns, water enters the intake chamber 3-1 of hollow shaft 3 upper ends by the circular water inlet 1-1 of housing, then discharges by the osculum 3-2 of hollow shaft 3 lower ends; When the intake chamber 3-1 of hollow shaft 3 upper ends leaves the circular water inlet 1-1 on housing 1, the sealed circle 2 of circular water inlet 1-1 on housing 1 stops, water cannot enter hollow shaft 3, now, the osculum 3-2 of hollow shaft 3 lower ends not there are flowing out, at hollow shaft 3, often rotating a circle just to have in the fan-shaped arc length of 60 ° has water supply, remains in 300 ° of arc length and stops supplying water, and realizes the object of rotation intermittent water application.
