Abstract
The utility model relates to an increasing and reducing type electric regulating valve, which is composed of a motor operator, a connector, and a valve, wherein, the motor operator speed reducing mechanism is a self-lubrication independent unit, and the gear modulus is 0.5-1; a position feedback assembly is a gear transmission mechanism; the connector is also a separate component, the upper part of the connector is provided with a key groove connected with the output shaft of the motor operator, and the bottom part of the connector is provided with a bolt used for a cone-shaped twisted hole and connected with the valve; a sealing surface between the valve body and the valve core is provided with an annular groove. The electric regulating valve has the advantages of light weight, favorable regulating performance, no need of maintenance, and convenient installation; therefore, the electric regulating valve can be used for an air conditioner heating system, wherein, the motor operator can also be used for the throttle control of an air conditioning system.
Description
The utility model belongs to the control electric valve of a kind of air-conditioning, heating system.
At present, along with the development of China's HVAC, air-conditioning cause and popularizing of concentrated supply of heating in the city, supporting with it electric control valve can not adapt to the needs of development.Existing electric control valve volume is bigger, and control performance is relatively poor, mainly shows following several respects:
A, electric actuator and valve are an overall structure, therefore, very flexible, installation inconvenience, the specification kind is incomplete, and control performance is unreliable, and electric actuator can not be as independently actuator's use.
The reducing gear volume of b, electric actuator is very big, and its module design is unreasonable.
C, valve event resistance are big, so just need join the electric actuator of high thrust, make whole electric control valve volume bigger.
The poor sealing performance of d, valve, ubiquity seepy question.
The purpose of this utility model provides a kind of improved electric control valve, reduces volume, improves control performance and make installation, uses more convenient.
Increasing-and-decreasing type electric control valve of the present utility model is made up of electric actuator, link, valve, and wherein electric actuator comprises shell, speed reducer, motor and position feedback assembly; Link comprises frame, rack and pinion drive mechanism, position fixing knob, compression spring, lock nut, valve rod, bolt; Valve comprises valve body, spool, valve rod, Sealing; It is characterized in that:
The speed reducer of electric actuator is a selflubricating separate unit formula structure, and the modulus of its gear is 0.5～1; The position feedback assembly is a gear drive, and wherein feedback potentiometer is a variable resistor;
Link is independent parts, and its top has keyway to be connected with the electric actuator output shaft, and its bottom is connected with valve with bolt by the drilling of taper strand; The end of rack and pinion drive mechanism is with a pressurized cluster spring, and it is connected with threaded stem, has the aperture that scale can be pointed out valve on the frame;
One less Sealing is arranged between valve body in the valve and the spool, and be provided with annular groove.
Because the electric actuator in the increasing-and-decreasing type electric control valve of the present utility model is an overall structure independently, therefore, use and install very flexible, and electric actuator can also be as actuator independently, except that connecting to form the electric control valve with valve, can also connect to form MOD with air door, also can be used for the various occasions that need to rotate, promote control.
The reducing gear of electric actuator is a fine module gear, and the power of each gear is by critical value design, therefore, makes that volume reduces, compact appearance.Position feedback assembly in the electric actuator is gear transmission, can adjust the specification of feedback potentiometer (getting final product the power transformation resistance) according to customer requirements.
The link of the utility model increasing-and-decreasing type electric control valve is independent parts, under manual case, valve is transferred to correct position after, tighten screw, the switching position of valve can be fixed; The bolt that connects frame and valve is strand drilling taper bolt, can make the electric actuator and the frame rotation arbitrarily on 360 ° of horizontal planes that are positioned at the valve top, to avoid the obstacle on the on-the-spot mounting point.
Because link and valve joint have a pressurized cluster spring that frame and valve are linked together, make because of water system changes the power that acts on the valve rod that is produced and obtain buffering, the pressurized cluster spring can move in the horizontal direction, makes valve rod and tooth bar coaxial.
Sealing surface on the utility model valve is provided with annular groove, and it is very narrow that Sealing is made, thereby make leakage rate become very little, and the Flow characteristics of valve is an equal percentage characteristics.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of the utility model electric actuator.
As shown in the figure: the utility model is made up of electric actuator, link, valve three parts.Wherein electric actuator 19 shell 14, speed reducer 15, motor 16 and position feedback assembly 17 wherein respectively is integral, and its output shaft 18 is connected with the top of link, and be fixing by screw 1.Link comprises position fixing knob 2, tooth bar 3, pressurized cluster spring box 4, pressurized cluster spring post 5, lock nut 6, strand drilling taper bolt 7, frame 8.Valve comprises valve body 9, spool 10, Sealing 11, valve rod 12, is provided with annular groove 13 on sealing surface.The pressurized complex spring comprises two springs.For reducing the noise of speed reducer, wherein a speed change gear can adopt reinforced plastic to make, and the selflubricating measure of speed reducer is to establish lubricated malthoid in geared end.For improving the dust sealing performance, adopt dust-proof sealing structure between electric actuator loam cake and the shell.
The bore scope φ 15～φ 50 of this electric control valve, energy consumption 10W, torque/time is 10NM/55S, 90 ° of Λ～180 ° Λ of angle stroke, straight journey 20～40mm, valve characteristic are equal percentage, the power supply of electric actuator is an alternating current 220V, 50HZ.
Electric control valve of the present utility model is mainly used in the flow of control hot water or cold water in air-conditioning, the heating system, electric actuator wherein is except that connecting to form the electric control valve with valve, can also connect to form MOD with air door, electric actuator also can be used for the various occasions that need to rotate, promote control, becomes a kind of conventional automatic control equipment that is widely used.
