Abstract
The invention relates to an inflation pump for a low-pressure atomization spray gun for gardening and horticulture, particularly to a manual spraying inflation pump with an L-shaped piston ring and used for low-pressure atomization water or pesticide spraying, which belongs to the technical field of inflation pumps in an injection device. The sealing and leakage prevention between a pipe mouth of a water absorption pipe (11) and a water outlet of a pump cover (5) is a difficult problem. In the same way, the durable sealing and the leakage prevention of a piston ring are also difficult. The improved piston ring (9) is not round any longer and is characterized by an L-shape shown as a figure 4; the L shape is formed by additionally arranging a cylindrical skirt edge (9a) at the outer ring of an original O-shaped ring, and particularly the outermost circumference of the skirt edge (9a) is conical, i.e. the outer diameter of one end close to an opening is slightly larger than the outer diameter of one end close to an O-shaped position; a ring of digging slot (9b) with a dug part like a knife pushing slot is also arranged at the connected part of the O-shaped ring and the cylindrical inside so as to enable the skirt edge of the piston ring to be more easily microstretched; and nitrile-butadiene rubber can be used.
Description
Technical field
The present invention relates to a kind ofly for gardens, the manual spray blast pump that the L-type piston ring is arranged of the inflating pump of the low pressure atomizing spray gun of gardening, especially low pressure atomizing water spray or agricultural chemicals belongs to the inflating pump technical field in injection apparatus.
Background technique
Be used for gardens, the inflating pump of the low pressure atomizing spray gun 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), because being pushes down the mouth of pipe of the dress suction sleeve (11) on the pump housing of inflating pump by pump cover, and screwed in the major thread bottleneck of large blow-molded container by the internal thread of pump cover (5), well imagine, 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.Equally, the durable sealing of piston ring, anti-leak also are difficult to.
Summary of the invention
A kind of for gardens in order to make up, the inflating pump of the low pressure atomizing spray gun of gardening, especially the shortcoming of seal operation state due to the existing mechanism of the hand-operated air pump of low pressure atomizing water spray or agricultural chemicals, the invention provides a kind of method that labyrinth seal is arranged that pump housing top of the inflating pump by the low pressure atomizing spray gun installs additional, namely do not change original large structure, but the installation position that utilizes pump housing top to lay suction sleeve is provided with labyrinth seal, can improve the leakage present situation of inflating pump.Especially, provide a kind of inflating pump that the L-type piston ring is arranged, can further improve the leakage present situation of inflating pump, make the piston self compensation and more durable in use.
The technical solution used in the present invention is:
A kind of for gardens, the inflating pump of the method that labyrinth seal is arranged is adopted on the inflating pump of the low pressure atomizing spray gun 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 the first seal ring (1a), the second seal ring (2a), the 5th seal ring (5a) forms; 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 shown in FIG.) of large 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 the first seal ring (1a), the second seal ring (2a), the 5th seal ring (5a), suction sleeve (11), reduction valve (12), pump pad (13), air cushion sheet (14) forms.At the pump cover (5) of inflating pump water outlet but supporting boom jet nozzle assembly cooperating is separately arranged.Described handle (1) passes the macropore at pump cover (5) center actively, 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), and pump cover outlet port spring (4), and form the one-way valve in outlet port.The 6th seal ring (6a) that is provided with of the described pump housing (10) particularly, the 4th seal ring (4a), the 3rd seal ring (3a) are with the center of circle of water outlet; And the first seal ring (1a), the 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 to be pressed in the bottleneck of large 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.Existing improved piston ring (9) is not original circle, and it is characterized in that as Fig. 4 look L shaped, to add columnar shirt rim (9a) in the outer ring of original O type circle, particularly the outermost circumference of described shirt rim (9a) is conical, that is to say, the external diameter of an end of close opening is a bit larger tham the external diameter of an end of locating near O shape; Also be provided with a circle grooving (9b) that resembles push broach groove sample that cuts out in the joint of O type circle and columnar inside, so that the easier micro stretching contracting in the shirt rim of piston ring.The O type circle part of described L shaped piston ring (9) still is arranged on piston (8) former position of laying piston ring as before, preferably an end of the opening of described L shaped piston ring (9) at the bottom of pump, i.e. handle dorsad.The selection of described L shaped piston ring (9) can be used rubber-like, the soft plastic class, and leather, fabric particularly uses itrile group butadiene (NITRILE-BUTADIENR RUBBER) to be advisable.
The invention has the beneficial effects as follows: the design adopts the spray blast pump that the L-type piston ring is arranged, and has improved sealability and the operating mode quality of this series products.
