The utility model discloses a water flow adjusting valve used on a constant temperature gas water heater and provided with the water flow cut-off function. The water flow adjusting valve used on the constant temperature gas water heater and provided with the water flow cut-off function includes a casing assembly (1), a gear assembly (2), a flexible plate and stepping motor assembly (3), a valve body assembly (4) and a valve core assembly (5) provided with the water flow cut-off function. The water flow adjusting valve is characterized in that a valve core plug of the valve core assembly (5) provided with the water flow cut-off function is provided with a taper, and the valve core plug and a valve hole adopt the surface and line seal manner. The valve core of the water flow adjusting valve is skillfully improved and designed on the original structure base; and when the water flow adjusting valve is arranged at a minimum opening degree, the water flow amount is zero, and the water flow cut-off function is realized. Meanwhile, the characteristics of good product whole interchangeability and generality are structurally ensured. Due to the improvement, the operation mode that a tap water inlet main valve should be manually closed when a full-automatic water heater stops service can be changed fundamentally, the full-automatic water heater is endowed with the functions of automatic opening/closing and automatic timing opening/closing without manual intervention, and the real full automation is realized.
Description
Technical field
The utility model relates to a kind of flow control valve, particularly a kind of flow control valve that current end function that has that is used on the constant temp gas water heater.
Background technique
Former flow control valve has designed the function of minimum discharge when structural design.When flow control valve is in minimum aperture, still can guarantee constant minimum water flow through flow control valve, when the user of water heater need close water heater, must be through manual-lock tap water water inlet total valve.Full-automatic water heater just can't be realized the full-automatic of real meaning at all for this reason.
The model utility content
The purpose of the utility model is: to the problems referred to above, provide a kind of when flow control valve is in minimum aperture, water flow is zero, thereby realizes the flow control valve of current by function.
The purpose of the utility model realizes through following technical proposals:
A kind of flow control valve that current end function that has that is used on the constant temp gas water heater; Mainly by frame set, gear assembly, flexible board and stepper motor assembly, valve component with have the mangetic core assembly that current end function; It is characterized in that: said have current and have tapering by the spool plug of the mangetic core assembly of function, adopts the sealing means of face and line with valve opening.
As optimal way, said flow control valve is the turbo type flow control valve, also comprises printed board assembly, rotor assembly, contains the retainer assembly and the cap assemblies of temperature transducer.
As optimal way, said flow control valve is the axial flow flow control valve, also comprises volute rotor assembly, temperature sensor assembly, sensor circuit and wire harness embedding assembly.
The workflow of the utility model:
When drive part was received the pulse control signal that controller sends, stepper motor was started working, and the driven gear group is rotated; On the final stage output gear; A magnet is installed, and corresponding position has a Hall switch with it on the flexible board circuit board, and this position is the zero-bit of modulating valve.When output gear forwarded zero-bit to, the magnet on the gear just was positioned at the Hall top, made its output low potential.This moment valve wide open, water flow is maximum.
When valve when the direction that turns down is rotated, magnet leaves Hall, Hall output high petential, this moment, control circuit began to calculate pulse (just calculating the angle that turns over); Simultaneously, water flow sensor is sent out data on flows to controller, when forwarding predetermined angle to; If the requirement of water flow data fit, then controller stop pulse signal output, motor stall; As nonconforming, controller will send pulse signal fine tuning valve corner, make data reach requirement rapidly.When this moment, valve was in minimum aperture, water flow was zero.
In the aforesaid workflow; Automatically controlled structure is divided into modulating valve and two parts of water flow sensing unit; Pass through the aperture and collection water intake flux signal of Hall switch and Hall transducer regulating valve respectively; Each other coordinate to cooperate the mangetic core assembly after improving again, full-automatic gas-fired water heater has been possessed do not need manual intervention to close the function with time switch automatically, realized the full-automatic of real meaning.The water inlet also is provided with temperature transducer, gathers the tap water water temperature that water intake is come in.
Wherein the correlation technique parameter of modulating valve and water flow sensing unit is following:
1. modulating valve stepper motor technical parameter:
The number of phases: 4 phases
Driving voltage: DC24V+10%
Step-by-step impulse: 250PPS
No load current :≤900mA
Stepping angle: 7.5 °/64.34+7%
Reduction speed ratio: 1/64.34
2. modulating valve Hall transducer technical parameter:
Voltage rating: 3.8～30VDC
Current drain :≤10mA
Work output voltage :≤0.4V
Work output current :≤20mA
Leakage current :≤10uA
Operating temperature :-50 ℃～160 ℃
Output rise time: 1.5uS
Output fall time: 1.5uS
3. water flow sensor Hall transducer technical parameter:
Voltage rating: 2.1VDC～24VDC
Rated current: 1.1mA～5.0mA
Saturation voltage:＜0.5VDC
Leakage current:＜0.5uA
Output rise time: 0.04uS
Output fall time: 0.04uS
The beneficial effect of the utility model:
Owing to adopted technique scheme, fundamentally having changed must be through closing the operator scheme of tap water water inlet total valve manually when full-automatic water heater is stopped using.Full-automatic gas-fired water heater has been possessed do not need manual intervention to close the function with time switch automatically, realized the full-automatic of real meaning.Flow control valve is owing to the stepper motor that adopts, so use pulsed drive, rotation angle is accurate; And do not have cumulative error, stepper motor further slows down through reduction gear, has improved corner accuracy; Increase moment of rotation, made the motion of spool accurate, thereby obtained accurate water flow data.The utilization of this technology makes the constant temperature technology of gas water-heater that comprehensive raising arranged.
