Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As Fig. 1, gate-valve device shown in Figure 2, this device is mainly by gate valve casing 1, flashboard 2, driving mechanism is formed, driving mechanism comprises motor 19, worm type of reduction gearing 6, connecting rod 3, gearwheel 4, small gear 5, the worm screw that motor 19 drives in the worm type of reduction gearing 6 is rotated, worm screw is taken worm gear to, the worm gear projecting shaft is connected with small gear 5 by coupling, small gear 5 and gearwheel 4 engagements, drive gearwheel 4 rotations during rotation, gearwheel 4 is connected with flashboard 2 by connecting rod 3, gearwheel 4 and connecting rod 3 are connected by bearing pin, and flashboard 2 is movably connected on the gate valve casing 1 by flashboard bearing 7.During gearwheel 4 rotations, connecting rod 3 drives flashboard 2 and opens or closes.Worm and gear has auto-lock function, guarantees the sealing force when flashboard 2 cuts out.By rationally setting the length of connecting rod 3, and diameter, the position of gearwheel 4 can effectively reduce that flashboard 2 is opened, needed driving force when sealing in the gate valve.In order to guarantee flashboard 2 stress equalizations, flashboard 2 uses symmetrical two small gears 5, gearwheel 4, connecting rod 3 to drive.
The latus rectum of gate valve is according to using needs to set in this device, and in the present embodiment, the latus rectum of gate valve is 1280mm, and the diameter of flashboard 2 is than the big 20～60mm of latus rectum, and flashboard 2 diameters are 1320mm in this enforcement.In order to guarantee that sealing force is even, flashboard 2 is designed to upper flashboard 8 and lower flashboard 9 double panel structures, as shown in Figure 3, Figure 4 at the middle part of upper flashboard 8, lower flashboard 9, bearing pin 10 is fixed on the lower flashboard 9 by nut 13 clamp sleeves 12, lower flashboard 9 seals, between bearing pin 10 and the lower flashboard 9 sealing gasket 11 is housed, reveals to prevent lower flashboard 9.Upper flashboard 8 is enclosed within on the sleeve 12, can slide up and down.When opening flashboard 2, upper flashboard 8 upwards slides along sleeve 12, drives lower flashboard 9 by nut 13, bearing pin 10; When closing flashboard 2, upper flashboard 9 to lower slider, by fore-set 17, is delivered to lower flashboard 9 with impacting force, as shown in Figure 5 along sleeve 12.Fore-set 17 can be provided with 8～12, evenly distributes along the circumferencial direction of upper flashboard 9, and fore-set 17 is provided with 9 in the present embodiment.The extrusion of fore-set 17 can be screwed into degree of depth adjustment by changing screw 15 in screw seat 14, screw seat 14 is weldingly fixed on the upper flashboard 8, is provided with butterfly spring 16 between screw 15 and the fore-set 17.Stud with Stamping Steel Ribbon 18 on the lower flashboard 9, combine with sealing surface, realize sealing, the extrusion of adjusting fore-set 17 can guarantee that sealing force is evenly distributed.The thickness of upper and lower flashboard 8,9 is calculated by its diameter and working pressure and obtains, and motor and the self-locking worm gear worm reducer 6 with double output shaft calculate according to required driving force tries to achieve.This gate-valve device is applicable to that working pressure is not more than the occasion of 0.1MPa, and in the present embodiment, working pressure is 5KPa, and upper and lower flashboard 8,9 thickness are 20mm.
