Abstract
The utility model relates to a sequential diversion valve, which comprises a valve body with a cylindrical inner cavity and three vent holes and one exhaust hole formed on the side wall thereof, and a cylindrical valve core positioned in and combined with the inner cavity of the valve body in a sliding way, wherein an axial air inlet is formed at the top of the valve core, a radial air outlet which rotates around the valve core is communicated correspondingly with the three vent holes on the valve body in sequence, and the axial air inlet and the radial air outlet are communicated to form an air inlet passage; an air discharge duct, which rotates around the valve core and can be communicated with the three vent holes on the valve body and the air exhaust hole at the same time, is arranged along the external periphery of the valve core; a coupling spindle connected with the output shaft of a stepping motor is arranged at the bottom end of the valve core, and the coupling spindle extends out of the valve body; a valve cover mounted at the top of the valve body is included in the utility model as well, and a through hole corresponding with the axial air inlet of the valve core is formed thereon. The utility model can realize the sequential air charging and discharging at the same time of the external counter-pulsating device, thereby greatly simplifying the structure of the external counter-pulsating device and reducing the size thereof; and the structure thereof is simple.
Description
Technical field
This utility model relate to a kind ofly dash, drain tap, specifically be that a kind of external counterpulsation apparatus that is applied to can be realized the filling of sequential-type, deflated sequential switching valve.
Background technology
Be used for the external counterpulsation apparatus in the medical treatment at present, commonly used fill, exhaust mode is that break-make by the control electromagnetic valve realizes, and the response speed of general electromagnetic valve does not reach, do not have enough big latus rectum, complex structure.And need to install a plurality of electromagnetic valves on the external counterpulsation apparatus, external counterpulsation apparatus is complicated, cause volume big, cost is also high.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of sequential switching valve, it can realize the sequential-type inflation and the aerofluxus simultaneously of each air bag of external counterpulsation apparatus, not only solved the shortcoming that adopts a plurality of valves on the device, and it is simple in structure, also simplify external counterpulsation apparatus greatly, dwindled its volume.
In order to address the above problem, this utility model by the following technical solutions: this sequential switching valve comprises:
Valve body is provided with cylindric inner chamber, and sidewall is provided with three passages, a steam vent;
Spool is cylindric, places body cavity and for being slidingly matched; The spool top is provided with the axial admission hole, and also being provided with one on the spool can the corresponding successively radially venthole that communicates with three passages on the valve body with valve core rotation, and described axial admission hole, radially venthole is communicated with and forms inlet channel; Around the outer circumference surface of spool one section air discharge duct that three passages on the valve body and steam vent can be communicated with simultaneously with valve core rotation is set; The bottom of spool is provided with the coupling spindle that is connected with the output shaft of motor, and this coupling spindle stretches out valve body;
Valve gap is installed in the top of valve body, and which is provided with the through hole corresponding with the axial admission hole of spool.
As further technical scheme of the present utility model:
In this sequential switching valve, be provided with sealing ring between the outer circumference surface of described spool and the valve interior wall.
In this sequential switching valve, be provided with sealing ring between described valve gap and the valve body.
In this sequential switching valve, described valve gap, valve body and sealing ring between the two are fixed together by bolt.
The beneficial effects of the utility model are: sequential switching valve of the present utility model, can utilize motor to drive its accurate control rotary speed, realize the inflation and the aerofluxus simultaneously of all air bags of external counterpulsation apparatus by the mutual correspondence in the different hole on spool and the valve body as power source.Simple in structure, volume is little, helps simplifying the whole mechanism of external counterpulsation apparatus, cost is low; Help dwindling the overall volume of external counterpulsation apparatus, use to be convenient for carrying with family.
Description of drawings
Below in conjunction with drawings and Examples this utility model is described further:
Fig. 1 is the decomposition texture sketch map (anterior view) of this utility model embodiment;
Fig. 2 is another decomposition texture sketch map (rear view) of this utility model embodiment;
Fig. 3 is the assembly structure schematic perspective view of this utility model embodiment;
Fig. 4 is the assembly structure sketch map of this utility model embodiment;
Among the figure: 1 valve body, 11 passages, 12 steam vents, 2 valve gaps, 21 through holes, 3 spools, 31 axial admission holes, 32 ventholes radially, 33 air discharge ducts, 34 coupling spindles, 4 sealing rings, 5 sealing rings, 6 bolts.
The specific embodiment
Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, 2, 3, this sequential switching valve mainly comprises valve body 1, spool 3, valve gap 2.
During work, the gas that source of the gas produces enters into through hole 21 (this moment, steam vent 12 was closed) by air inlet pipe, and the axial admission hole 31 of flowing through flows to radially venthole 32.The rotation of motor simultaneously, make accurately radially venthole 32 successively with three passages, 11 corresponding communicating, realize the sequential-type inflation of each air bag.
After radially venthole 32 turns over three passages 11 successively, be rotated further, seasonable with 11 pairs of three passages simultaneously when air discharge duct 33, promptly three passages 11 are communicated with steam vent 12 by air discharge duct 33 simultaneously, open exhaustor, venting when promptly realizing each air bag.
