Description
Technical field
The present invention relates to a kind of gardens that are used for, the manual inflating pump that labyrinth seal is arranged of the inflating pump of the low pressure atomizing lance of gardening, especially low pressure atomizing spray or agricultural chemicals belongs to the inflating pump technical field in the injection apparatus.
Background technique
Be used for gardens, the inflating pump of the low pressure atomizing lance of gardening is widely used in inflating by the selected mode of people's hobby.The mouth of pipe of the dress suction sleeve (11) on the pump housing of existing inflating pump, water outlet with pump cover (5), owing to be the mouth of pipe of pushing down the dress suction sleeve (11) on the pump housing of inflating pump by pump cover, and screw in the major thread bottleneck of big blow-molded container by the internal thread of pump cover (5), well imagine that the mouth of pipe of described dress suction sleeve (11) is with the water outlet of pump cover (5), sealing between these two, anti-leak are hard nut to cracks.
Summary of the invention
In order to remedy a kind of gardens that are used for, the inflating pump of the low pressure atomizing lance of gardening, especially the shortcoming of seal operation state due to the existing mechanism of the hand-operated air pump of low pressure atomizing spray or agricultural chemicals, the invention provides the method that labyrinth seal is arranged that a kind of pump housing top of the inflating pump by the low pressure atomizing lance installs additional, promptly do not change original big bilge construction, but utilize pump housing top to lay the installation position of suction sleeve, and be provided with labyrinth seal, can improve the leakage present situation of inflating pump.
The technical solution used in the present invention is:
A kind of gardens that are used for, the inflating pump of the method that labyrinth seal is arranged is adopted on the inflating pump of the low pressure atomizing lance of gardening, especially pump housing top, it is characterized in that the mounting point of laying suction sleeve on the pump housing (10) top is provided with labyrinth seal; Described labyrinth seal is mainly by the 6th seal ring (6a), the 4th seal ring (4a), and the 3rd seal ring (3a), and first seal ring (1a), second seal ring (2a), the 5th seal ring (5a) is formed; So that the mouth of pipe of the dress suction sleeve (11) on the pump housing of inflating pump and the water outlet of pump cover (5) are suitable.The inflating pump that labyrinth seal is arranged is screwed in the major thread bottleneck (not drawing among the figure) of big blow-molded container by the internal thread of the big circumference of pump cover (5); The described inflating pump that labyrinth seal is arranged, by handle (1), plastic spacer (2), fluorine rubber ball (3), pump cover outlet port spring (4), pump cover (5), suction sleeve rubber pad (6), piston check valve spring (7), piston nonreturn valve core (7a), piston (8), piston ring (9), the pump housing (10) and the 6th seal ring (6a) that is provided with thereof, the 4th seal ring (4a), the 3rd seal ring (3a), and first seal ring (1a), second seal ring (2a), the 5th seal ring (5a), suction sleeve (11), reduction valve (12), pump pad (13), air cushion sheet (14) is formed.At the pump cover (5) of inflating pump the water outlet place but supporting boom jet nozzle assembly cooperating is arranged in addition.Described handle (1) passes the macropore at pump cover (5) center versatilely, and piston (8) interlock, and is pressed with piston check valve spring (7) and piston nonreturn valve core (7a) in the centre of handle (1) and piston (8).The external rings week of described piston (8) is equiped with piston ring (9), inserts the described pump housing (10) and back and forth activity.Several holes are arranged at the bottom of the described pump housing (10), are provided with the air cushion sheet, and described air cushion sheet is rubberlike flexible member, forms actual one-way valve.Install successively into plastic spacer (2) outside of the water outlet of described pump cover (5), fluorine rubber ball (3), pump cover outlet port spring (4), and the one-way valve in composition outlet port.The 6th seal ring (6a) that the particularly described pump housing (10) is provided with, the 4th seal ring (4a), the 3rd seal ring (3a) are with the center of circle of water outlet; And first seal ring (1a), second seal ring (2a), the 5th seal ring (5a) and the pump housing (10) concentric.Reduction valve (12) is located on the pump housing, and pressure is excessive to be washed open.Pump pad (13) is the bottleneck that is pressed in big blow-molded container by pump housing limit.The external rings week installing piston ring (9) of described piston (8) also must fat liquoring.Described piston nonreturn valve core (7a) preferably is advisable with fluorine rubber.
The invention has the beneficial effects as follows: the design adopts the inflating pump that labyrinth seal is arranged, and has improved the sealability and the operating mode quality of this series products.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic perspective view that the pump housing (10) of a plurality of labyrinth seal rings is arranged of the present invention.
Fig. 2 is an exploded perspective view of the present invention.
As depicted in figs. 1 and 2, among the figure: 1. are handle (1); 2. be plastic spacer (2); 3. be fluorine rubber ball (3); 4. be pump cover outlet port spring (4); 5. be pump cover (5); 6. be suction sleeve rubber pad (6); 7. be piston check valve spring (7); 8. be piston nonreturn valve core (7a); 9. be piston (8), piston ring (9); 10. be the pump housing (10); Which is provided with the 6th seal ring (6a), the 4th seal ring (4a), the 3rd seal ring (3a), and first seal ring (1a), second seal ring (2a), the 5th seal ring (5a); 11. be suction sleeve (11); 12. be reduction valve (12); 13. be pump pad (13); 14. be air cushion sheet (14).
Embodiment
Use the present invention that the inflating pump of labyrinth seal is arranged; Be provided with labyrinth seal because lay the mounting point of suction sleeve on the pump housing (10) top, and described labyrinth seal is mainly by the 6th seal ring (6a), the 4th seal ring (4a), the 3rd seal ring (3a), and first seal ring (1a), second seal ring (2a), the 5th seal ring (5a) is formed, so the water outlet of the mouth of pipe of the dress suction sleeve (11) on the pump housing of inflating pump and pump cover (5) be sealed with improvement.Handle (1), plastic spacer (2), fluorine rubber ball (3) are gone in installing successively, pump cover outlet port spring (4), pump cover (5), suction sleeve rubber pad (6), piston check valve spring (7), piston nonreturn valve core (7a), piston (8), piston ring (9), the pump housing (10) and the 6th seal ring (6a) that is provided with thereof, the 4th seal ring (4a), the 3rd seal ring (3a), and first seal ring (1a), second seal ring (2a), the 5th seal ring (5a), suction sleeve (11), reduction valve (12), pump pad (13), air cushion sheet (14) is formed the described inflating pump that labyrinth seal is arranged.Added soup, the internal thread of the big circumference of pump cover (5) has been screwed in the major thread bottleneck of big blow-molded container; Install supporting boom jet nozzle assembly at the water outlet place of the pump cover (5) of inflating pump again and get final product work.During last handle (1), piston (8) and piston ring (9) are up, and air cushion sheet (14) one-way valve closes, and the piston nonreturn valve core (7a) that ambient air passes out enters in the pump.When pressing down handle (1), piston nonreturn valve core (7a) closes, air cushion sheet (14) one-way valve is opened, air inlet, pressure raises in the big blow-molded container, thus soup is through suction sleeve (11), through labyrinth seal and the water outlet of few outer leakage, and through open by fluorine rubber ball (3), the one-way valve that pump cover outlet port spring (4) is formed sprays by supporting boom jet nozzle assembly again.So go round and begin again.
