Be one kind can high temperature resistant (such as 65 DEG C -148 DEG C) low-power consumption miniature electric three-way ball valve.
Background technique
Electric three passes ball valve has sum-bit three-position valve.The former is 0-90 ° of actuating range, and there are two types of positions；There are three types of positions by the latter
It sets, 0 °, 90 ° and 180 °, realize flow path switching or closes.Need to meet following require: control angle three to its Electronic control
Valve needs to reach 180 °；The power of driving three-way valve will meet the torque of valve rotation；It is exactly accurate to the control of valve location,
Especially to be sealed at closed position；Valve transfer speed is fast.The electric three passes ball valve of domestic commerce is mainly for 1/2 English
The switch valve (two) of the very little above larger size, 0-90 ° of actuating range, 90 ° rotation time 15-60 seconds.There are 90 ° and 180 ° in foreign countries
1/4 inch and commercialized electric three passes ball valve below, 90 ° of rotation times are relatively fast, and 2.5-4 seconds；But its electronic execution
The volume of mechanism is larger, operating voltage is higher (24VAC/110VAC/220VAC)；Because of electric operator and triple valve distance between tie rods
Relatively close, the operation temperature of valve is not higher than 65 °；For the electric operator of 24V low-work voltage, at full capacity because of its motor
(100%) the problem of operation, valve position is reset automatically after valve does not receive switching command, cools down when having overheating protection.It is this kind of electronic
On the one hand valve is not suitable for high heat flow path (such as 65 DEG C -148 DEG C).On the other hand, when system needs to control there are multiple valves, at
Ben Taigao, while also increasing the power consumption and volume of system.
Combined using digital rudder controller with gear drive realization to the control of valve location be a kind of compact, it is low at
This executing agency.Duty ratio by adjusting input PWM wave (pulse width modulation) realizes that it swings to suitable position,
180 ° of steering engines can accurately control the angle of steering engine by high level.Certain import instruments, as Aerodyne company of the U.S. produces
Aerosol chemistry component on-line computing model ACSM and secondary aerosol species oxidation generate reactor PAM, be using digital rudder controller
Come control valve position.This kind of miniature electric threeway is mainly for lesser 1/8 valve of torque, in addition, it is impossible to be used in high temperature ring
The automatic control in border.
To simply implement, the large torque in electric three passes ball valve design, small size, low-power consumption, hot environment is available wants
It asks, for the utility model using commercialized three-way ball valve as object, the principle of foundation digital rudder controller angle control simultaneously plays its volume
It is small and exquisite, structure is simple, lower-cost advantage, have developed a kind of miniature electric three-way ball valve.
