Description
Technical field
The present invention relates to valve technology field, and in particular to a kind of motor-driven valve for refrigeration system.
Background technology
Motor-driven valve is the high-end valve in Self controlling valve, and it can not only realize on-off action, and adjustment type motor-driven valve can also realize valve position regulatory function.The stroke of YE can be divided into:Two kinds of 90 ° of angle strokes and Direct Travel, particular/special requirement can also meet 180 °, 270 °, 360 ° of total travels.The valve of angle stroke is used with the YE of angle stroke, realizes 90 ° of valve with inward turning control pipeline fluid on-off;The YE of Direct Travel coordinates the valve of Direct Travel to use, and realizes that valve plate moves up and down control pipeline fluid on-off.
Motor-driven valve is exactly briefly with electronic actuator control valves door, so as to realize the on and off of valve.It can be divided into upper and lower two parts, and top half is YE, and the latter half is valve.
Motor-driven valve is divided to two kinds, and one kind is angle stroke motor-driven valve：The valve of angle stroke is used with the YE of angle stroke, realizes 90 degree of valve with inward turning control pipeline fluid on-off；Another kind is straight stroke electric valve：The valve of Direct Travel is used with the YE of Direct Travel, realizes that valve plate moves up and down control pipeline fluid on-off.Generally supported the use in automaticity equipment higher.
Motor-driven valve is generally coupled together by electric operator and valve, by turning into motor-driven valve after installation and debugging.Motor-driven valve is connected electric operator as power using electric energy and drives valve, realizes switch, the regulation action of valve.So as to reach switch or regulation purpose to pipeline medium.
The electric device part of the motor-driven valve of prior art is fragile, it is necessary to improve.
The content of the invention
Defect and deficiency it is an object of the invention to be directed to prior art, there is provided a kind of simple structure, the motor-driven valve for refrigeration system reasonable in design, easy to use.
To achieve the above object, the technical solution adopted by the present invention is：It includes valve plate, valve body, valve rod, upper lid, vavle shelf, electric device, nut, main box, case lid, valve rod cover；Described valve body upper end is fixedly connected with upper lid；Valve plate is inserted with described valve body, valve plate upper end is connected with valve rod, and the bottom of valve rod is plugged in lid；Held on described upper lid and be fixedly connected with vavle shelf, the upper end of vavle shelf is connected with main box, and main box upper end is provided with case lid, and endoporus and the valve rod cover of case lid cooperate；Electric device is provided with described main box；Described electric device includes output shaft, roller bearing；Nut is provided with the top of described valve rod, nut outer wall cooperates with output shaft inwall；Roller bearing is provided between described output shaft and main box.
Preferably, described roller bearing is taper roll bearing.
Preferably, described output shaft inwall, the upper end of nut are provided with lock sleeve.
Preferably, being provided with sealing ring between described main box and case lid.
Operation principle of the invention is：Using electric energy as power come by executing agency --- electric device drives, and the opening and closing action of valve plate is realized, so as to reaching the through-flow purpose of control pipeline medium；Taper roll bearing effectively prevent the damage of output shaft.
After said structure, what the present invention was produced has the beneficial effect that：A kind of motor-driven valve for refrigeration system of the present invention, easy to operate, long service life, maintenance cost is low, and the present invention has the advantages that simple structure, sets reasonable, low manufacture cost.
