Description
Technical field
The present invention relates to a kind of oil pump, particularly one first sprays quantitative liquid and sprays compressed-air actuated oil pump again.
Background technique
In production process, need one first to spray quantitative liquid and spray compressed-air actuated device again, this device can be realized by the additional control system of the combination of solenoid valve, oil pump.But this compound mode system complex, increases cost, reduces reliability.
Summary of the invention
The object of this invention is to provide simple, the reliable oil pump of a kind of structure.
Technological scheme of the present invention is: a kind of oil pump, valve body one end arranges suction port, plunger compartment is extended inward as along suction port, plunger is placed in plunger compartment and plunger compartment is slidably connected, rollback baffle plate being set between suction port and plunger compartment, for limiting the limit position of plunger rollback, bottom plunger compartment, being provided with advance baffle plate, for limiting the limit position of plunger advancement, rollback spring is set between plunger and the distal end faces of plunger compartment;
Be provided with liquid sucting port, described liquid sucting port is positioned at the end of plunger compartment, and is connected with pick-up tube, arranges steel ball in liquid sucting port, and this steel ball and liquid sucting port form one-way mechanism, and liquid can only enter plunger compartment from liquid sucting port and can not reverse flow;
Be provided with mouth spray, described mouth spray is positioned at the distal end faces place of plunger compartment, and with the outlet conducting of the valve body the other end, in mouth spray outlet, steel ball and spring are set, form one-way mechanism;
Be provided with gas circuit, described liquid passage inlet is between rollback baffle plate and the plunger under touching forward gear board status, and described gas circuit outlet is positioned at mouth spray outlet outside.
The advantage that the present invention has and good effect are: structure is simple, reliable, and when suction port passes into pressurized air, outlet first sprays quantitative liquid and sprays pressurized air again.

Embodiment
As shown in Figure 1, the present invention includes valve body 2, in valve body 2, be provided with inlet hole 1, plunger compartment 13, gas circuit 3, liquid sucting port 12, mouth spray 6 and outlet 9; Inlet hole 1 and UNICOM of plunger compartment 13, rollback baffle plate 15 is set between inlet hole 1 and plunger compartment 13, for limiting the position of plunger 14 rollback, advance baffle plate 5 is provided with bottom plunger compartment 13, for limiting the limit position that plunger 14 advances, rollback spring 4 is set between the distal end faces of plunger 14 and plunger compartment 13; The end of plunger compartment 13 arranges liquid sucting port 12, and is connected with pick-up tube 11, arranges liquid sucting port steel ball 10 in liquid sucting port 12, and described liquid sucting port steel ball 10 and liquid sucting port 12 form one-way mechanism, and liquid can only enter plunger compartment 13 and can not reverse flow from liquid sucting port 12; The distal end faces of plunger compartment 13 also arranges mouth spray 6, mouth spray 6 and outlet 9 conductings, and between steel ball 7 is set and spring 8 forms one-way mechanism, only have liquid when extruding by plunger 14 just to enter outlet 9 from mouth spray 6; Between the appropriate location and outlet 9 of plunger compartment 13, gas circuit 3 is set, under this appropriate location refers to the state touching advance baffle plate at plunger 14, position between rollback baffle plate 15 and plunger 14, when pressurized air promote plunger 14 run to stopped by advance block 5 time, gas circuit 3 is communicated with suction port 1 and outlet 9.
The working procedure of this example: when suction port 1 passes into pressurized air, promote plunger 14, plunger 14 promotes liquid, fluid pressure and gravity own make liquid sucting port steel ball 10 close liquid sucting port 12, liquid promotes steel ball 7 along mouth spray 6 and is ejected into outlet 9, has sprayed quantitative liquid when plunger 14 is stopped out of service by advance block 5; Now plunger 14 no longer closes gas circuit 3, pressurized air runs to outlet 9 along gas circuit 3 and sprays, plunger 14 rollback under rollback spring 4 acts on when pressurized air stops, the process of rollback produces negative pressure at liquid sucting port 12 and mouth spray 6, because mouth spray 6 is closed by steel ball 7 and spring 8, the negative pressure of liquid sucting port 12 makes liquid push liquid sucting port steel ball 10 open along pick-up tube 11 and enters plunger compartment 13, plunger 14 return back to and stops stopping by baffle plate 15, now plunger compartment 13 has sucked quantitative liquid, for next action is got ready.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
