Specific embodiment
This utility model is described in detail below in conjunction with embodiment and accompanying drawing, it should be pointed out that described
Embodiment be intended merely to facilitate to understanding of the present utility model, and any restriction effect is not played to it.
Referring to shown in Fig. 1 and Fig. 2, a kind of dosing pump of the present embodiment, including the upper pump casing 501 and lower pump body that are fixedly connected with each other
504, piston 511, clamp nut 508 and spring 503 are provided with dosing pump, spring 503 is placed on the cavity of lower pump body 504
It is interior, and be set on piston 511, spring 503 can help piston 511 to reset, and upper end and the clamp nut 508 of piston 511 connect
Connect, be provided with piston 511 and clamp nut 508 in fluid passage, clamp nut 508 and be provided with (this reality of check valve 502
Apply example and select duckbill valve), gasket seal 507 is provided between clamp nut 508 and upper pump casing 501.The left and right two of upper pump casing 501
Side is separately provided for connecting the pipe joint of flushing line.
Preferably, the fairlead 510 that guiding piston 511 moves up and down is additionally provided with dosing pump.The lower end of lower pump body 504
Be additionally provided with base 512, lower check valve 505 is provided with base (the present embodiment selects duckbill valve).The bottom of lower pump body 504 sets
It is equipped with the pipe joint 506 being connected with pipeline.In Fig. 1, horizontal arrow 509 show the water (flow) direction of flushing water, erects shown in arrow 513
For cleaning agent Way in.As shown in Fig. 2 the dosing pump in this enforcement can be fixed on vacuum by screw and fixed plate 514
It is convenient to install in feces collecting system.
The operation principle of the dosing pump of the present embodiment is：When upper pump casing 501 has pressure washing current out-of-date, piston 511 exists
Move down in the presence of pressure, while drive clamp nut 508 to move down, the sealing between clamp nut 508 and upper pump casing 501
It is destroyed.Now, the space between two duckbill valves is compressed, and pressure becomes big, and lower duckbill valve is closed, and upper duckbill valve is opened, interior
The cleaning agent in portion enters upper pump casing 501, and with flushing water closet is entered.
After the completion of flushing, the flushing water pressure release in upper pump casing 501, piston 511 is moved upwards under spring force
It is dynamic, while driving moved on clamp nut 508, sealing is re-established between clamp nut 508 and upper pump casing 501.Now, cleaning agent
Under the motion of piston 511, in being sucked into the pump housing.
