Description
Technical field
The utility model relates to a kind of spraying equipment, particularly relates to a kind of airless sprayer being applicable to airless spraying.
Background technology
High pressure airless spray equipment utilizes high-pressure plunger pump coating to be pressurized to 3000PSI (210kg/cm), and the coating obtaining high pressure is transported to spray gun by high-pressure hose, forms atomization via nozzle release pressure, thus forms fine and close coating at surface of wall.Because coating atomization does not need compressed air, therefore be called airless spraying.High pressure airless spray equipment operationally, under the effect of gas, make the piston up-down in cylinder, paint medium enters from suction valve body, and successively by coating cylinder, pump seat, the coating in coating cylinder is extruded by out splice going splice by the air pressure produced by cylinder, due to common airless sprayer coating from be drawn into extrusion the path of process longer, not only energy loss is comparatively large, and easily produces pulse, thus affects coating quality.
Utility model content
The airless sprayer that the technical problems to be solved in the utility model is to provide that a kind of path is short, less energy consumption, pulse are few, reliable.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises pressurized cylinder, be located at the plunger rod in pressurized cylinder, voltage stabilizing cylinder is connected with below described pressurized cylinder, described voltage stabilizing cylinder side is connected with input assembly and exports assembly, described voltage stabilizing cylinder is provided with and sucks cavity and export cavity, be respectively equipped with inhalation check valve and export check-valves in described suction cavity and output cavity, described suction cavity is connected with input assembly, described output cavity is connected with output assembly, described voltage stabilizing cylinder is also provided with shunting cavity, shunting plug is provided with in described shunting cavity, described shunting cavity respectively with voltage stabilizing cylinder cavity, suck cavity to be connected with output cavity.
As preferably, be provided with vacuum back-flow pipe between described output assembly and pressurized cylinder, described vacuum back-flow tube cavity is interconnected with output assembly cavity and pressurized cylinder cavity.
As preferably, described input assembly by sucking filter housing, be located at the suction filter core of filter housing one end, ball valve forms.
As preferably, described pressurized cylinder upper end is provided with connecting plate, and described connecting plate is fixedly connected with some guide rods, and the described guide rod other end is fixedly connected with voltage stabilizing cylinder.
The utility model compared with prior art, has following obvious advantage and beneficial effect:
1, short, the less energy consumption in path.Due to input assembly of the present utility model with export assembly and be arranged at voltage stabilizing cylinder side, coating from enter into extrusion the path of process shorter, thus effectively reduce power consumption.
2, pulse is few, reliable.Because the utility model is provided with vacuum back-flow pipe between pressurized cylinder and output assembly, coating can, under the effect of vacuum back-flow pipe, be augmented in pressurized cylinder, and the generation of pulse when being conducive to reducing spraying, improves coating quality.

Fig. 2 is the top view after Fig. 1 removes connecting plate;
Fig. 3 is voltage stabilizing cylinder structure schematic diagram in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
As shown in Figure 1 to Figure 3: the utility model comprises pressurized cylinder 1, be located at the plunger rod 2 in pressurized cylinder 1, voltage stabilizing cylinder 3 is connected with below pressurized cylinder 1, voltage stabilizing cylinder 3 side is connected with input assembly 5 and exports assembly 6, voltage stabilizing cylinder 3 is provided with and sucks cavity 7 and export cavity 8, suck cavity 7 be respectively equipped with inhalation check valve 9 with output cavity 8 and export check-valves 10, suck cavity 7 to be connected with input assembly 5, export cavity 8 to be connected with output assembly 6, voltage stabilizing cylinder 3 is also provided with shunting cavity 11, shunting plug 12 is provided with in shunting cavity 11, shunting cavity 11 respectively with voltage stabilizing cavity 13, suck cavity 7 to be connected with output cavity 8, export between assembly 6 and pressurized cylinder 1 and be provided with vacuum back-flow pipe 15, vacuum back-flow pipe 15 inner chamber is interconnected with output assembly 6 cavity and pressurized cylinder 3 cavity, input assembly 5 is made up of suction filter housing 16, the suction filter core 17 being located at suction filter housing 16 one end, ball valve 18, pressurized cylinder 1 upper end is provided with connecting plate 19, connecting plate 19 is fixedly connected with some guide rods 20, and guide rod 20 other end is fixedly connected with voltage stabilizing cylinder 3.
The utility model operationally, when moving upward under the effect of plunger rod 2 at piston, owing to forming negative pressure in pressurized cylinder cavity, at this moment inhalation check valve 9 is opened, coating enters from input assembly 5, through sucking cavity 7, shunting cavity 11 enters in voltage stabilizing cavity 13 and pressurized cylinder cavity, completes coating input process, when the moved downward of plunger rod 2 at piston, at this moment inhalation check valve 9 is closed, the coating in pressurized cylinder cavity through shunting cavity 11, export cavity 8 and enter into and export assembly 6, complete coating output procedure, in addition when plunger rod 2 is moving downward in process, pressurized cylinder 1 upper end cavity forms negative pressure, at this moment can the coating exported in assembly 6 be back in pressurized cylinder 1 cavity by vacuum back-flow pipe 13, and when plunger rod 2 is when moving upward, the coating of pressurized cylinder 1 upper end backflow again can be extruded to and export in assembly 6, and sprayed by spray gun, and be at this moment just export check-valves 10 to close, voltage stabilizing cylinder 3 supplements coating process, and the coating in voltage stabilizing cavity 13 cannot be transported in output assembly 6, thus effectively the deficiency reduced because exporting coating content in assembly 6 causes the generation of pulse phenomenon, thus improve coating quality.
