Abstract
The utility model discloses a kind of automatically controlled adjustable flow control valve unit, mainly formed by suction port, air outlet, steel ball, housing, threaded mandrel, stepper motor, seal ring; Described suction port is arranged at housing center bottom; Described air outlet is arranged at housing side; Described steel ball is surrounded by the large hemisphere face of threaded mandrel top indent; Described threaded mandrel bottom is inserted in housing, top is connected with the output shaft of stepper motor by flat hole; This automatically controlled adjustable flow control valve unit, has changed traditional adjustable flow valve and has adopted the several complicated approach that can export the metering hole of different flow and control respectively by several solenoid valves; Overall structure is simple compact, use components and parts less, easy to assembly, and low cost of manufacture, reliability are strong.
Description
Technical field
The utility model relates to oxygenerator Flow valve applied technical field, especially a kind of automatically controlled adjustable flow control valve unit.
Background technique
At present, the oxygenerator of flowmeter is not installed in use, the different time, generally need to be exported different flows, to meet the oxygen uptake demand under different situations.The several metering holes that can export different flow of many employings, control respectively by several solenoid valves at present, reach the requirement of output different flow; Such complicated structure, is in particular in: the gas circuit of connection is mixed and disorderly; The components and parts that adopt are many, and reliability decrease, cost of production be high, it is large to take up room, assembling is complicated, inefficiency; For making up the deficiencies in the prior art, the utility model aims to provide a kind of automatically controlled adjustable flow control valve unit.
Model utility content
For the problems referred to above, the utility model aims to provide a kind of automatically controlled adjustable flow control valve unit.
For realizing this technical purpose, scheme of the present utility model is: a kind of automatically controlled adjustable flow control valve unit, is mainly made up of suction port, air outlet, steel ball, housing, threaded mandrel, stepper motor, seal ring; Described suction port is arranged at housing center bottom; Described air outlet is arranged at housing side; Described steel ball is surrounded by the large hemisphere face of threaded mandrel top indent; Described threaded mandrel bottom is inserted in housing, top is connected with the output shaft of stepper motor by flat hole.
Preferably, be provided with the circular hole with the conical surface in described housing, its conical surface part is valve base and the ball-type valve that packs the threaded mandrel in it into, jointly forms ball-type valve pair.
Preferably, the secondary both sides of described ball-type valve, connect respectively suction port and air outlet.
Compared with prior art, the beneficial effects of the utility model are: this automatically controlled adjustable flow control valve unit, has changed traditional adjustable flow valve and adopted the several complicated approach that can export the metering hole of different flow and control respectively by several solenoid valves; Overall structure is simple compact, use components and parts less, easy to assembly, and low cost of manufacture, reliability are strong.
Brief description of the drawings
Fig. 1 is overall cross-sectional view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the automatically controlled adjustable flow control valve unit of the utility model embodiment's one, is mainly made up of suction port 1, air outlet 2, steel ball 3, seal ring 4, housing 5, threaded mandrel 6, stepper motor 7; Described suction port 1 is arranged at housing 5 center bottom; Described air outlet 2 is arranged at housing 5 sides; Described steel ball 3 is surrounded by the large hemisphere face of threaded mandrel 6 top indents; Described threaded mandrel 6 bottoms are inserted in housing 5, top is connected with the output shaft of stepper motor 7 by flat hole.
Preferably, be provided with the circular hole with the conical surface in described housing, its conical surface part is valve base and the ball-type valve that packs the threaded mandrel in it into, jointly forms ball-type valve pair.
Preferably, the secondary both sides of described ball-type valve, connect respectively suction port 1 and air outlet 2.
Further, described automatically controlled adjustable flow control valve unit, its working principle is: when described stepper motor and described threaded mandrel, together pack in described housing, just form one and passed through setting program by described stepper motor, export satisfactory stepping angle, output shaft can on average be exported weekly certain stepping angle displacement, control the corner of described threaded mandrel, the two synchronous operation, make the ball-type valve at threaded mandrel top produce satisfactory straight-line displacement, thereby control the distance between ball-type valve and valve base, make valve pair produce different gaps under difference requires, thereby produce different flows, reach the requirement that meets user.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any reference character in claim should be considered as limiting related claim.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle amendment that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
