Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of a kind of variable volume diaphragm pump of the utility model as Figure 1-3, comprises the pump housing 1 and pump cover 9, and described pump cover 9 is arranged on the sidewall of the described pump housing 1 and is fixedly connected with by bolt 10, between the described pump housing 1 and described pump cover 9, is fixedly installed diaphragm 11; Described diaphragm 11 center is fixedly connected with piston rod 12, the right-hand member of described piston rod 12 is spherical structure and is movably connected on piston shoes 13, described piston shoes 13 are nested in the chute 141 of offering on rotating disk 14, the center hinge of described rotating disk 14 is connected to live axle 15, described live axle 15 is rotatably connected on described pump cover 9, in described live axle 15, be arranged with controlling rod 16, the left end of described controlling rod 16 and rotating disk 14 chain connections, the right-hand member of described controlling rod 16 offers tapped hole 161, and described tapped hole 161 internal threads are connected with adjusting bolt 17.
As optimization, the bottom of the described pump housing 1 is provided with water intake 2, and the top of the described pump housing is provided with water outlet 7, and described water intake 2 is connected with described water outlet 7; Be provided with the first one-way valve 3 at the described pump housing 1 near water intake 2 ends, be provided with the second one-way valve 6 at the described pump housing 1 near water outlet 7 ends; Described the first one-way valve 3 and the second one-way valve 6 are used for playing the effect of liquid one-way conduction; In the time of inspiration liquid, the first one-way valve 3 conductings, the second one-way valve 6 closures, liquid enters cavity 8 from water intake 2 by the first one-way valve 3; In the time discharging liquid, the second one-way valve 6 conductings, the first one-way valve 3 closures, liquid is discharged from water outlet 7 by one-way valve 6.
As optimization, described the first one-way valve 3 and the second one-way valve 6 include steel ball 5 and steel ball seat 4, between described steel ball 5 and steel ball seat 4, closely cooperate, and realize good sealability, ensure the good usability of diaphragm pump.
As optimization, in described adjusting bolt 17, be provided with limiting stopper 171, in described live axle 15, be provided with restraining groove 151, described limiting stopper 171 embeds and is connected in described restraining groove 151.
As optimization, described live axle 15 is fixedly connected with gear 18 by key 19.
Specifically, drive unit (not shown) by gear 18 by transmission of power to live axle 15, described live axle 15 drives rotating disk 14 to circle with the axial direction of live axle 15, owing to being certain angle between rotating disk 14 and live axle 15, therefore rotating disk 15 drives piston rod 12 to make horizontal reciprocating movement in the process of rotating.
In the time that needs regulate barrier film pump delivery, to reduce barrier film pump delivery as example: need to clockwise rotate adjusting bolt 17, because adjusting bolt 17 remains unchanged by limiting stopper 171 and the relative position of live axle 15, therefore tightening along with adjusting bolt 17, controlling rod 16 relative drive shafts 15 move right, because left end and the rotating disk 14 of controlling rod 16 are hinged, therefore rotating disk 14 diminishes with the angle of live axle 15 under the effect of controlling rod 16, thereby realize reducing of piston rod 12 horizontal displacements, finally realize reducing of diaphragm pump discharge capacity.
A kind of variable volume diaphragm pump of the utility model, by regulating adjusting bolt 17 can change the angle between rotating disk 14 and live axle 15, changes the stroke of piston rod 12, thereby reaches the effect that changes diaphragm pump flow; Simple in structure easy to use, there is higher practicability.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
