Detailed description of the invention

Below in conjunction with Figure of description, this utility model is described in detail, it should be noted that enforcement of the present utility model It is not limited to following embodiment.

As Figure 1-Figure 2, a kind of light-duty diaphragm pump, including reducing motor 10, eccentric shaft 3, turnover pipe-line system 1, Chamber volume 4, diaphragm 5, reciprocating shaft 2, clamp flange 6；Chamber volume 4 be fixed on turnover pipe-line system 1 inner side, and with Turnover pipe-line system 1 connects, and diaphragm 5 is arranged on the opposite side of chamber volume 4, is sealed with chamber volume 4 by clamp flange 6 Connecting, reciprocating shaft 2 is connected with diaphragm 5, and eccentric shaft 3 is in transmission connection with reciprocating shaft 2, eccentric shaft 3 and reducing motor 10 Output shaft connect.

Described turnover pipe-line system 1 includes rectangular box-like turnover pipeline 1-4, steel ball valve 1-3, spring 1-2, plug 1-1, Steel ball valve 1-3 is arranged on four corner location of turnover pipeline 1-4, compresses location, another of spring 1-2 by spring 1-2 End is locked by plug 1-1, is provided with import 8 in the lower end of turnover pipeline 1-4, is provided with in the upper end of turnover pipeline 1-4 Outlet 7.

Steel ball valve 1-3 is arranged on the inboard of rectangular box-like turnover tetra-joint angles of pipeline 1-4, at the inwall of turnover pipeline 1-4 Being provided with boss structure to position for steel ball valve 1-3 one end, the other end of steel ball valve 1-3 is fixed by spring 1-2, Plug 1-1 is threadedly secured to pass in and out the end at tetra-angles of pipeline 1-4, on the one hand pressing spring 1-2, on the other hand locking Seal.

Described steel ball valve 1-3 is check valve, and it includes that steel ball 1-3-1, steel ball rack 1-3-2, steel ball 1-3-1 are placed on steel ball rack In 1-3-2, being provided with through hole in the lower end of steel ball rack 1-3-2, the aperture of this through hole is less than steel ball 1-3-1 diameter.Due to gravity Effect steel ball 1-3-1 compresses and seals through hole, when fluid media (medium) enters turnover pipeline 1-4 from lower end import 8, and fluid pressure By steel ball 1-3-1 jack-up and enter inlet/outlet pipe road 1-4 circulation, owing to the effect of steel ball 1-3-1 gravity and fluid buffer brake makes Steel ball 1-3-1 tightly pushes down through hole, so that the fluid in turnover pipeline 1-4 can only one-way flow from bottom to up.

Each side arrange a chamber volume 4, chamber volume 4 and turnover pipeline 1-4 in turnover pipeline 1-4 pass through pipeline Fixing connection, the other side of chamber volume 4 is open architecture, and diaphragm 5 is buckled in chamber volume 4 and is locked by clamp flange 6 Tightening seal, is formed by importing and exporting the unidirectional two-way pipe-line system that pipeline 1-4, chamber volume 4 and diaphragm 5 form.Reciprocating shaft 2 Two ends be bolted with diaphragm 5, the centre position of reciprocating shaft 2 is provided with open slot, by open slot and eccentric shaft 3 Connect.When reducing motor 10 drives eccentric shaft 3 to rotate, eccentric shaft 3 can promote reciprocating shaft 2 to swing.Work as volume When diaphragm 5 inside room 4 inwardly pulls, chamber volume 4 volume increases, the steel ball valve 1-3 of 4 connecting line upper ends of chamber volume Cut-off, the steel ball valve 1-3 of lower end is open-minded, and fluid is inhaled into chamber volume 4.When diaphragm 5 presses laterally, chamber volume 4 Volume reduces, and the steel ball valve 1-3 cut-off of 4 connecting line lower ends of chamber volume, the steel ball valve 1-3 of upper end is open-minded, chamber volume 4 Interior fluid media (medium) is from outlet 7 extrusion.

Reducing motor 10 alternately pulls and presses left and right diaphragm 5 by eccentric shaft 3 and reciprocating shaft 2, periodically changes left and right The volume of chamber volume 4, thus the fluid media (medium) in promoting pipe-line system constantly is flowed to export 7 by import 8 in a steady stream.

Diaphragm 5 in this utility model uses polyurethane flat board diaphragm, and diaphragm is manufactured simple, with low cost.Diaphragm 5 It is connected sealing, it is easy to dismounting, it is simple to maintenance and repair with using anchor ear flange 6 between chamber volume 4.Steel ball valve 1-3 passes through bullet Spring 1-2 and plug wire 1-1 fixes, it is simple to maintenance is changed.Miniature low-power machine drives the operational mode of low deflection diaphragm to make This use new structure is the simplest, small volume and less weight, energy-conservation low-power consumption, increase the service life simultaneously.
