Fig. 2 is the schematic top plan view of respirator spiral flow adjustable valve of the present utility model;
Fig. 1-2 is the most preferred embodiment of respirator spiral flow adjustable valve of the present utility model, wherein: 1 spigot joint 2 sliding sleeves, 3 valve bodies, 4 stage clips, 5 screw rods, 6 catch, 7 plane scroll springs, 8 motors, 9 glands, 10 backing pins, 11 bearings, 12 sliding rod racks, 13 slide bars, 14 bulb stopper bars, 15 bulb stoppers, 16 spools, 17 valve seats, 18 optocoupler assemblies.
The specific embodiment
Shown in Fig. 1-2, make a respirator spiral flow adjustable valve of the present utility model, manufacturing process is as follows: a) adopt a motor 8 and a single-lead screw rod 5 that is associated in together, along with motor 8 rotates, the helicoid of screw rod 5 is just along with rotation.B) the bulb stopper assembly that connects together comprises bulb stopper 15, bulb stopper bar 14, slide bar 13, sliding Heavenly Stems and Earthly Branches frame 12, bearing 11.c) inner conical surface spool 16.D) by the valve block 17 of air inlet and gas outlet, valve block 17 internal fixation spools 16 and bulb stopper assembly.E) valve body 3 is used for fixing motor 8, plane scroll spring 7, gland 9, valve block 17.F) bulb stopper 15 is combined closely with spool 16 inner conical surfaces in order to have a power failure, and gas can not pass through, and adopts a plane scroll spring 7 that the helicoid of screw rod 5 is resetted, for preventing plane scroll spring 7 off-centre, the plane scroll spring 7 outer glands 9 that are provided with.G) adopt a plane bearing 11, increase bearing 11 and closely contact, the frictional force when also reducing simultaneously screw rod 5 rotations with the helicoid of screw rod 5.H) screw rod 5, bulb stopper 15 adopt wear-resisting hard material with spool 16, increase the reliability and the concordance of respirator spiral flow adjustable valve.I) valve block 17 have air inlet and gas outlet spigot joint 1 so that be connected with other pipelines.Respirator spiral flow adjustable valve of the present utility model, bulb stopper 15 adopts spherical, and spool 16 adopts inner conical surface, the profile of valve block 17 is cuboids, valve body adopts the cuboid frame structure, such respirator spiral flow adjustable valve, the point-device control rate of flow of fluid of energy; Bulb stopper 15 adopts the one side that contacts with spool 16 to adopt the spherical outside surface body and another side employing cylinder, spool 16 adopts Internal Spherical Surface, the profile of valve block 17 is cylinder bodily forms, valve body 3 adopts the cuboid frame structure, such respirator spiral flow adjustable valve also can point-device control rate of flow of fluid.Operation principle and work process are as follows:
1, the original state of respirator spiral flow adjustable valve: screw rod 5 is by the elastic force playback (zero-bit) of plane scroll spring 7, screw rod 5 pressed closer bearing 11 and made bulb stopper 15 closely contact with spool 16 inner conical surfaces this moment, sliding rod rack 12, slide bar 13, bulb stopper bar 14, bulb stopper 15, bearing 11 are connected as a single entity and form the bulb stopper assembly, gas can not flow to the gas outlet by spool 16 from air inlet, catch 6 and optocoupler assembly 18 are used to detect the playback of screw rod 5, and backing pin 10 is used for playback (zero-bit) position of adjustable screw bar 5.
2, gas flow controlled state from small to large: motor 8 rotates and drives screw rods 5 rotations, sliding rod rack 12 is pulled away from spool 16 to bulb stopper 15 gradually by stage clip 4 elastic force between sliding sleeve 2 and the sliding rod rack 12, make bulb stopper 15 and spool 16 inner conical surface gaps increase gradually, this moment, gas also changed by the flow that spool 16 flows to the gas outlet gradually from small to large from air inlet.
3, gas flow controlled state from big to small: motor 8 rotates and drives screw rods 5 rotations, the spiral of screw rod 5 pushes up bearing 11 to spool 16 gradually, make bulb stopper 15 and spool 16 inner conical surfaces dwindle gradually, this moment, gas also changed by the flow that spool 16 flows to the gas outlet gradually from big to small from air inlet, until closing.
Alternate by three processes of above-mentioned gas flow 1-3 can realize the accurate control to gas or fluid flow.
