Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.In addition, all connection/annexations related in patent, not singly refer to that component directly connects, and refer to and according to concrete performance, can connect auxiliary by adding or reducing, and form more excellent connecting structure.Each technical characteristics in the utility model, can combination of interactions under the prerequisite of not conflicting conflict.
Please refer to Fig. 1, the diaphragm pump of the utility model band buffer structure comprises valve component 10, pump assembly 20 and Power Component 30.
Valve component 10 comprises valve body 11, liquid flowing valve sheet 12, draining valve sheet 13, flexible sheet 14 and upper cover 15, and described valve body 11 is provided with feed liquor runner 111, discharge opeing runner 112, feed liquor Buffer Pool 113 and discharge opeing Buffer Pool 114.Described liquid flowing valve sheet 12 is located at the port that described feed liquor runner 111 is communicated with described pump assembly 20, and described draining valve sheet 13 is located at the port that described discharge opeing runner 112 is communicated with described pump assembly 20.Described feed liquor runner 111 is provided with feed liquor Buffer Pool 113, described discharge opeing runner 112 is provided with discharge opeing Buffer Pool 114, described flexible sheet 14 sealing is overlying on described feed liquor Buffer Pool 113 and discharge opeing Buffer Pool 114, the upper cover 15 be connected with valve body 11 is located on described flexible sheet 14, utilizes the coupling mechanism force between upper cover 15 and valve body 11 flexible sheet 14 sealing to be pressed on described feed liquor Buffer Pool 113 and discharge opeing Buffer Pool 114.It should be noted that, the flexible sheet 14 playing sealing energy storage effect in the utility model on two Buffer Pools is preferably as a whole, but in various embodiments, flexible sheet 14 can be set to two and be covered on two Buffer Pools respectively, in addition, the present embodiment Elastic diaphragm 14 is preferably elastomer diaphragm.
Pump assembly 20 comprises pump body 21 and diaphragm 22, and described pump body 21 inside is provided with inner chamber 211.Described pump body 21 is fixed on the lower end of described valve body 11, the coupling mechanism force between pump body 21 and valve body 11 is utilized to fix above-mentioned liquid flowing valve sheet 12 and draining valve sheet 13, described diaphragm 22 envelope is located at one end of described inner chamber 211, inner chamber 211 is made to become the cavity of a variable volume, when diaphragm 22 pumps, the volume of inner chamber 211 will change, and then forms the power of feed liquor and discharge opeing.
Power Component 30 comprises support 31 and driving mechanism 32, and described driving mechanism 32 comprises electric machine main shaft 321 nested successively, eccentric wheel 322, bearing 323 and connecting rod 324, and described connecting rod 324 is connected with above-mentioned diaphragm 22.When electric machine main shaft 321 is with movable eccentric wheel 322 to rotate, the connecting rod be connected on eccentric wheel 322 just can drive diaphragm 22 to pump.
For better understanding the technical program, the existing concrete structure of two prevailing operating state to diaphragm pump in conjunction with the utility model diaphragm pump further illustrates.
Please with reference to Fig. 2 and Fig. 3.Connecting rod 324 drives diaphragm 22 to pump, and inner chamber 211 volume of pump body 21 is changed.Specifically, when diaphragm 22 down moves, inner chamber 211 volume becomes large, produces negative pressure instantaneously, liquid is sucked feed liquor Buffer Pool 113 from feed liquor runner 111, then sucks in inner chamber 211, and in this process, draining valve sheet 13 is closed, and liquid flowing valve sheet 12 is opened; When diaphragm 22 up moves, draining valve sheet 13 is opened, and liquid flowing valve sheet 12 is closed, and is discharged by liquid, namely complete a work cycle from inner chamber 211 through discharge opeing Buffer Pool 114 and discharge opeing runner 112.
Diaphragm pump is opened, closedown, or valve open, turn-off transient, because liquid exists inertia, produces shock wave.This shock wave finally acts on Buffer Pool flexible sheet 14, makes diaphragm deforms, eliminates shock wave, thus plays the effect of protection liquid-way system component, also eliminates by impacting the noise produced meanwhile.Inhale, arrange the effect of power at diaphragm pump under, Buffer Pool flexible sheet 14 up-down stretch, forms the structure being similar to accumulator, stored energy with feed liquor Buffer Pool 113, discharge opeing Buffer Pool 114.When liquid sucking-discharging flow, pressure surge, flexible sheet 14 towards the direction variation reducing fluctuation, thus will keep the stability of flow, pressure.
More than that better enforcement of the present utility model is illustrated, but the utility model is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
