Abstract
The utility model relates to an electric regulating valve of which the technical field belongs to the design for a valve. The electric regulating valve is composed of a stepping motor, a worm screw, a worm wheel, a brace table, a fixed plate, a catch plate, blades, an air door cover, a flange plate, etc., wherein, the stepping motor 2 and the worm screw 3 are fixedly connected with the fixed plate 6 through the brace table 5, the worm wheel 4 is fixedly connected with the catch plate 7, the fixed plate 6 is connected with the catch plate 7 through a bolt 9, and the blades 8 (eight blates) are positioned between the fixed plate 6 and the catch plate 7. One end of each blade is connected with the fixed plate 6, and the other end is connected with the catch plate 7. The regulating valve of the utility model leads flow area to be uniformly varied, and enhances flow quality and regulating precision. With simple structure, the utility model is suitable for air regulation on all occasions.
Description
The utility model relates to a kind of device that utilizes stepper motor and controller to realize regulating automatically air quantity, and its technical field belongs to valve design, and international Patent classificating number is F16K.
In the prior art, the valve that is used to regulate air quantity mostly is the dish valve, and this class valve is widely used in industrial departments such as electronics, chemical industry, vacuum, metallurgy.Be used for dust, gas, high-temperature gas etc. are carried out that automatic or manual is regulated and the valve that cuts off also has the louvered modulating valve (ZSCYV that produces as Zhejiang Rui'an City instrument and meter for automation valve head factory
b, ZSCYV
b-0.5 electronic blinds circle formula, window formula valve).Problems such as it is big that above-mentioned modulating valve ubiquity structure weight, and the flow field of fluid is inhomogeneous when changing flow area have many inconveniences as executive component in automatic control system.
For addressing the above problem, the utility model provides a kind of and has passed through the stepper motor damper by controller, make the flow area of air door be the concentric circle variation, be applicable to air quantity control, the furnace pressure control of automatic burner, and the electric control valve that the air quantity of the various occasions such as air quantity adjusting of hot and cold wind is controlled automatically in the central air-conditioning system.
The utility model is realized in the following way: this modulating valve is made up of controller, stepper motor, worm gear, worm screw, price fixing, dial, blade, air door lid and flange plate; Worm gear connects by fastening piece with dial, worm screw and stepper motor link together by support platform and price fixing, blade (8) place between dial and the price fixing, one end of blade is connected on the price fixing by pin, the other end is connected with the sliding-groove of dial by pin, dial is connected by two bolts with price fixing, and an end and the dial of bolt are connected, and the other end links to each other with the sliding-groove of price fixing.Stepper motor drives worm screw after receiving the instruction of controller, and worm screw drives worm gear again, and the rotation of worm gear drives dial makes blade or opens or close, thereby plays the effect of regulating air quantity.

Now by reference to the accompanying drawings the utility model is described in detail: with reference to Fig. 1, the utility model is by control Device 1 processed, stepper motor 2, worm screw 3, worm gear 4, price fixing 6, driver plate 7, blade 8, Ring flange 10 formations such as grade; Stepper motor 2 is installed on the brace table 5 brace table with worm screw 3 5 are connected by bolt and price fixing 6; Worm gear 4 and driver plate 7 are connected by bolt; Blade 8 (8) place between price fixing 6 and the driver plate 7. With reference to Fig. 4, an end of blade 8 passes through the hole 14 with price fixing 6 on hole 12 be connected by pin, blade 8 can be sold around this Nail rotation, the other end gathering sill 13 by on hole 15 and the driver plate 7 is connected by pin, This pin can move in groove; Driver plate 7 is connected by bolt 9 with price fixing 6, one of bolt 9 End is fixed on the driver plate 7, and the other end links to each other with groove 11 on the price fixing 6, and this bolt can be at groove 11 interior slips; Wind gate cover is installed in the another side of price fixing 6; Wind gate cover and worm gear 4 connect respectively Upper flange plate 16 is used for connecting blast pipe and discharge pipe. Stepper motor 2 is received controller 1 Instruction after drive worm screw 3 and worm gear 4 rotations, 7 rotations of 4 drive driver plates of worm gear. When dialling When dish 7 rotated, blade 8 one ends rotated at price fixing 6 around the pin by hole 14, another End then is limited in the gathering sill 13 interior slips of driver plate 7 by the pin by hole 15. Work as worm gear 4 is driver plate 7 when clockwise rotating, and blade 8 closes up mutually, and namely circulation area reduces, when dialling When dish 7 rotated counterclockwise, blade 8 opened mutually, and namely circulation area increases. Circulation area Size is the size of air inflow is driven worm screw 3 by stepper motor 2 by controller 1 angle of rotation Degree is regulated.
Electric control valve of the present utility model has following good effect:
1. adopt the method for new adjusting circulation area, the flow field quality of air-flow is improved, circulation area has realized even variation from big to small or from small to large, and degree of regulation is greatly improved.
2. simple in structure, volume is less, and weight is lighter, is applicable to that more the air quantity of various occasions is regulated.
Embodiment: Fig. 5 has provided an embodiment's of the present utility model erection drawing.
