Fig. 2 is the structural representation of single-pass flow switch in the embodiment shown in Figure 1.
Number in the figure is:
1 drug storage bottle; 2 medicine supplying pipe roads; 3 control valves; 4 water storage bottles; 5 electrical switches; 6 control circuits; 7 water supply lines; 8 single-pass flow switches; The 8-1 valve body; 8-2,8-8 flow into union joint; 8-3,8-9 sealing gasket; 8-4 flows out union joint; The 8-5 locking nut; 8-6 " O " shape sealing ring; 8-7 regulates core bar.
The specific embodiment
As depicted in figs. 1 and 2, the water supply of oral medical equipment described in the utility model, confession medicine system comprise water storage bottle 4 and the water supply line 7 that is connected with water storage bottle 4, drug storage bottle 1 and the medicine supplying pipe road 2 that is connected with drug storage bottle 1, and single-pass flow switch 8, wherein,
Described single-pass flow switch 8 comprises valve body 8-1, the longitudinal hole that offers water route inflow entrance and medicinal liquid inflow entrance (position of offering of two inlets is preferably on the same horizontal plane) on the valve body 8-1 and be communicated with these two inlets, the end of two inlets is installed respectively and is flowed into union joint 8-2,8-8, be provided with silica gel sealing pad 8-3, the 8-9 of loudspeaker dress between described inflow union joint 8-2,8-8 and the inlet, sealing pad 8-3, the end that the 8-9 bore is big join with inflow union joint 8-2,8-8; Longitudinal hole is installed near an end of two inlets and is flowed out union joint 8-4, this flows out union joint 8-4 and is communicated with water route on the working handle by pipeline, the other end of longitudinal hole is installed and is regulated core bar 8-7, be provided with between the outer peripheral face of this adjusting core bar 8-7 and the inner peripheral surface of longitudinal hole that silica gel material makes " O " shape sealing ring 8-6, ooze out from the top that valve body 8-1 goes up longitudinal hole to prevent water or liquid medicine; Described adjusting core bar 8-7 outer surface offers screw thread, with the locking nut 8-5 threaded engagement that is fixed on the valve body 8-1, realize to regulate core bar 8-7 moving in vertical direction; The bottom of described adjusting core bar 8-7 is a cone structure and over against the endoporus that flows out union joint 8-4;
Described water supply line 7 and medicine supplying pipe road 2 are connected with inflow union joint 8-2,8-8 on 8 two inlets of single-pass flow switch respectively, are provided with electromagnetic valve or peristaltic pump on the path in water supply line 7 and medicine supplying pipe road 2; Described electromagnetic valve is connected with electrical switch 5 on the control circuit 6, by the work of electromagnetic valve or peristaltic pump on two pipelines of these electrical switch 5 controls.
In the above-mentioned water system, sealing gasket 8-3,8-9 are little horn-like of the big end of bore one end, and the big end of bore with flow into union joint 8-2,8-8 and join.During control valve 3 on closing water supply line 7, flow to the inflow union joint 8-8 that is connected with water supply line 7 from medicine supplying pipe road 2 through flowing into the effusive medicinal liquid of union joint 8-2, because the effect medicinal liquid of pressure can dash the small-caliber end of sealing gasket 8-9 and insert its heavy caliber end, and then block the endoporus of the inflow union joint 8-8 that is connected with water supply line 7, effectively stop medicinal liquid to flow into water supply line 7.When closing medicine supplying pipe road 2, situation is identical.In addition, offer screw thread owing to regulate core bar 8-7 outer surface, make itself and the locking nut 8-5 that is fixed on the valve body 8-1 form threaded engagement, thereby regulate core bar 8-7 by rotation and realize regulating core bar 8-7 moving in vertical direction, again because to regulate the bottom of core bar 8-7 be cone structure and over against the endoporus that flows out union joint 8-4, therefore, can regulate the gap that core bar 8-7 controls cone-shaped bottom and flows out the endoporus of union joint 8-4 by rotation, thereby reach the purpose of regulating flow.
