The model utility content
For addressing the above problem, the utility model provides a kind of liquid sorption pump, and fluid is smooth, and has the back suction function, can not cause the liquid water clock that remains in drain pipe.
The technological scheme that the utility model is taked is: a kind of liquid sorption pump; Comprise the pump housing, liquid inlet pipe, drain pipe, feed liquor one-way valve, fluid one-way valve, back suction piston and cushion dashpot; The pump housing comprises pump housing piston, is connected drive wheel and pump housing shell on the pump housing piston; Liquid inlet pipe is provided with the feed liquor one-way valve and is connected with the pump housing, and drain pipe is provided with the fluid one-way valve and is connected with cushion dashpot and with the pump housing, and the back suction piston is arranged in the drain pipe and with drive wheel and joins; It is flexible that moving runner drives the back suction piston, and it is up and down that moving runner drives pump housing piston.
In technique scheme, cushion dashpot can be elastic structure.
In technique scheme, the fluid one-way valve is arranged on before the cushion dashpot, and the back suction piston is arranged between fluid one-way valve and the cushion dashpot.
In technique scheme, the moving runner outer rim is provided with and the corresponding drive wheel breach of back suction piston.
In technique scheme, the back suction piston is the elasticity bascule.
In technique scheme, the top and bottom of the pump housing all are connected with liquid inlet pipe and drain pipe.
In technique scheme, drain pipe comprises liquid outlet pipe, first drain pipe and second drain pipe, and an end of first drain pipe and second drain pipe is being connected the pump housing, and the other end of first drain pipe and second drain pipe is being connected the liquid outlet pipe.
In technique scheme, first drain pipe and second drain pipe all are provided with the fluid one-way valve.
In technique scheme, cushion dashpot is arranged on the liquid outlet pipe.
The beneficial effect of the utility model is: the liquid sorption pump of above-mentioned structure, because the top and bottom of the pump housing all are connected with liquid inlet pipe and drain pipe, and the uninterrupted fluid of drain pipe, and utilize cushion dashpot to adjust the continuous and smoothness of fluid, the drain pipe fluid is smooth; Owing to the back suction function of back suction piston, remain in the liquid that can not water clock of drain pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, the pump housing; 11, pump housing piston; 12, drive wheel; 121, drive wheel breach; 13, pump housing shell; 2, liquid inlet pipe; 3, drain pipe; 31, liquid outlet pipe; 32, first drain pipe; 33, second drain pipe; 4, feed liquor one-way valve; 5, fluid one-way valve; 6, back suction piston; 7, cushion dashpot.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 has schematically shown the liquid sorption pump according to a kind of mode of execution of the utility model.
This liquid sorption pump comprises the pump housing 1, liquid inlet pipe 2, drain pipe 3, feed liquor one-way valve 4, feed liquor one-way valve 5, back suction piston 6 and cushion dashpot 7; The pump housing 1 comprises pump housing piston 11, is connected drive wheel 12 and pump housing shell 13 on the pump housing piston 11; Drain pipe 3 comprises liquid outlet pipe 31, first drain pipe 32 and second drain pipe 33; Liquid inlet pipe 2 is provided with feed liquor one-way valve 4 and the one of which end is connected with the pump housing 1; First drain pipe 32 and second drain pipe 33 are provided with the other end that feed liquor one-way valve 5 and one of which end be connected the pump housing 1, the first drain pipe 32 and second drain pipe 33 and are being connected liquid outlet pipe 31; Back suction piston 6 is arranged in the drain pipe 3 and with drive wheel 12 and joins; Moving runner 12 outer rims are provided with and back suction piston 6 corresponding drive wheel breach 121; Cushion dashpot 7 can be elastic structure, and cushion dashpot 7 is arranged on liquid outlet pipe 31, and feed liquor one-way valve 5 is arranged on before the cushion dashpot 7, and back suction piston 6 is arranged between feed liquor one-way valve 5 and the cushion dashpot 7; It is flexible that moving runner 12 drives back suction piston 6, and it is up and down that moving runner 12 drives pump housing piston 11, and back suction piston 6 is the elasticity bascule.
When using the utility model work, it is up and down that drive wheel 12 drives pump housing pistons 11, and liquid is sucked the pump housings 1 from liquid inlet pipe 2, because feed liquor one-way valve 4, liquid inlet pipe 2 can only unidirectional entering liquid; And then liquid released the pump housings 1 from drain pipe 3, because feed liquor one-way valve 5, drain pipe 3 can only unidirectional output liquid; Because the top and bottom of the pump housing 1 all are connected with liquid inlet pipe 2 and drain pipe 3, drain pipe 3 uninterrupted fluids, and utilize cushion dashpot 7 to adjust the continuous and smoothness of fluids, make liquid outlet pipe 31 fluids smooth.When the utility model quit work, back suction piston 6 sprang into drive wheel breach 121 places, utilized back suction piston 6 to inhale back the liquid of drain pipe 3 outlets, made the liquid that can not water clock that remains in drain pipe 3.
Above embodiment just is explanation rather than restriction the utility model, so all equivalences of being done according to the described method of the utility model patent claim change or modify, includes in the utility model patent claim.
