Description
Technical field
The invention belongs to valve control fields, are related to a kind of motor-driven valve flexible controller.
Background technique
Air conditioner end equipment, including fan coil, furred ceiling wind cabinet, Fresh air handling units, are typically mounted in indoor suspended ceiling layer, with
Central air conditioner system is connected by pipeline, and cold/hot water passes through coil pipe for air cooling-down or heating, then passes through blower for air delivery
To room；Usually every air conditioning terminal matches a motor-driven valve (or cold and hot two motor-driven valves), and by a temperature control panel by room
Interior user manipulates air conditioning terminal.
Motor-driven valve is the temperature controlled critical component of room conditioning, is mounted on the water inlet pipe of air conditioning terminal, and by temperature control
Panel control.Temperature control panel compared with indoor air temperature, is automatically switched motor-driven valve, to control Interior Space by set temperature
Temperature degree.Statistics discovery motor-driven valve is the highest component of failure rate in entire central air conditioner system, and major part, which is not stuck, is exactly
It is not closed completely.Existing motor-driven valve maintenance technique all has to dismantle valve body, and hundreds and thousands of motor-driven valves are all mounted on indoor suspended ceiling
In layer, maintenance or replacement are all extremely difficult；And often also subject to hydraulic pressure higher in pipeline in valve, there are also keep the temperature for valve body appearance
Sponge, when maintenance do not pay attention to slightly will leak, become the problem for perplexing entire central air-conditioning industry.
Simultaneously in use because in water dirt cause valve stuck, it is clear that it is all unrelated with valve producer and installation unit, this
Also seem customary as everybody, the problem of turning a blind eye to.
Therefore following comprehensive analysis is first carried out on this question:
1, use environment is analyzed: though electronic valve inlet is equipped with filter, it is biggish miscellaneous can only to filter particle in removing water
Matter；The water circulation system of central air conditioning huge for one, subtle impurity can not be filtered by usually having in water, such as solid ash
Calcium ions and magnesium ions etc. in dirt, water, while carbon steel piping can also generate rust mud for a long time in water.
In addition, central air conditioner system is usually intermittent, runs stage by stage, daytime is opened, and night closes, summer and winter fortune
Row；It especially is in shutdown status in the Spring Festival and several months in autumn, pipeline water circulating pump and motor-driven valve can also remain off the several months,
Water in pipeline can also be constantly in stationary state, and subtle impurity and rust mud can slowly be deposited on inner wall of the pipe and spool in water
Surface.And water temperature changes also very greatly in pipeline, and 7-12 DEG C of summer of water at low temperature can accelerate pipeline corrosion, winter 45-60
DEG C high-temperature water can then accelerate the calcification and hardening of spool face deposit.
2, object analysis
1) motor-driven valve controller is generally temperature control panel, is electrically connected with motor-driven valve, passes through the temperature control logic of temperature control panel
Its opening and closing is controlled, usual motor-driven valve controller is allowed electronic directly to one signal opened or closed of motor-driven valve
Valve disposably opens or closes, if spool encounters impurity foreign matter in movement, is yet to continue with and opens or closes, often just stuck
It is motionless, cause driving current excessive, the fever of motor-driven valve motor internal is burnt out to the end.And existing temperature control panel is only room conditioning
User service meets its easy to operate, beautiful, temperature control comfortably some requirements, so temperature control panel producer does not have yet at all
Reason considers the problems of that motor-driven valve is stuck or fits badly.
2) motor-driven valve: only focusing on motor-driven valve quality itself as valve manufacturer, such as seals pressure-resistant performance, electronic execution
Device electronic original part reliability, valve body structure intensity etc.；It is usually all to increase valve body to drive to solve the problems, such as that it is stuck that valve is easy
The power of dynamic motor, or spool material is improved, such as metal is changed to ceramics, but effect is paid no attention to from the point of view of practical application at present
Think, and often also add valve cost, reduce cost performance, because quality good valve again, also can not cope with scale not
Disconnected accumulation, so this problem is never included in its product quality problem by valve producer.
3) Pipe installing unit: consideration pipeline is water-tight, divides water uniform, and general only cleaning one was lauched upon installation
The impurity of filter, stuck by scale as motor-driven valve during operation, not it considers the problems of.
4) central air-conditioning management service unit: other than carrying out water treatment to recirculated water, also it can only repair or replace
Motor-driven valve only passively handles department, can not also solve root problem.
From above-mentioned analysis it is found that each object all acts in accordance with the division of their functions and duties, each object do not have, is also impossible on the whole and root
Analysis solves the problems, such as in sheet.Therefore, it is necessary to a kind of completely new motor-driven valve controller is designed, on the basis of not increasing hardware,
Not only it can be reduced the failure rate of motor-driven valve, but also central air-conditioning manager can be facilitated to carry out temperature control management to air-conditioning, and reduced operation energy consumption.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of motor-driven valve flexible controllers, and motor-driven valve is allowed to open using flexibility
Pass movement, is not easy spool in switch motion stuck.
The technical solution of invention is as follows:
A kind of motor-driven valve flexible controller, connect with motor-driven valve, can control the opening and closing of motor-driven valve；
It include flexible switch mode in the switch motion of the motor-driven valve flexible controller driving motor-driven valve, motor-driven valve moves
Make other than conventional directly switch, there are also flexible switch modes；I.e. the opening of motor-driven valve is opened using flexible way, or electricity
The closing of dynamic valve is closed using flexible way or the opening and closing of motor-driven valve all use flexible way；Or motor-driven valve work
Movement all uses flexible switch mode every time, or only uses flexible switch mode in the specific partial act of motor-driven valve.
The application places of many motor-driven valves, control medium inertia is larger, such as the dynamoelectric water valve in central air-conditioning, Shi Jimiao
Influence of the movement to air themperature can almost ignore；Motor-driven valve is different from the solenoid valve of snap action, switch motion simultaneously
Time generally has more than ten seconds, this may pass through for realization flexible switch.
Further, it is positive and negative gradual to refer to that electronic valve drive signal uses for the flexible switch mode, when motor-driven valve is by closing
To when opening, motor-driven valve opening signal is first given, allows one fragment position of spool forward motion, then gives motor-driven valve shutdown signal, makes spool anti-
To a fragment position, repeated several times is moved, each counter motion position is less than forward motion position, then fully open electronic
Valve, wherein forward and reverse movement is intermediate slightly to pause；Vice versa.
If the valve event time is 10 seconds, 5 seconds opening signals are first issued, stop 1 second, then issue 2 seconds shutdown signals, then stop
1 second, then 5 seconds opening signals are issued, stop 1 second, then issue 2 seconds shutdown signals, then stop 1 second, finally issues 4-6 seconds opening letters
Number, valve wide open.Vice versa；Which is primarily adapted for use in the motor-driven valve of the positive counter-movement of spool.
Further, the flexible switch mode refers to that the flexible switch mode refers to electronic valve drive signal using pulse
Formula first gives one opening signal pulse of motor-driven valve, then interrupt opening signal, later again first to electric when motor-driven valve is by closing to when opening
Dynamic one opening signal pulse of valve, repeated several times, fully open to motor-driven valve, vice versa.
If the valve event time is 10 seconds, 3 seconds opening signals are first issued, stop 1 second, then issue 3 seconds opening signals, are stopped
1 second, finally issue 4-6 seconds opening signals, valve wide open.Vice versa.
Spool is opened when which is primarily adapted for use in energization, and spring pushes spool to close the motor-driven valve resetted after power-off.This
Sample pushes counter motion by power transmission forward motion, spring to break, realizes that spool is flexible in opening procedure and opens.
Flexible switch mode, purpose are exactly to be moved back and forth by spool, make to be attached to spool face, or be stuck at spool
Impurity becomes to loosen, and prevents stuck, and in conjunction with the flowing of pipeline water, the impurity of loosening is washed away, spool is made to become flexible.
Further, the input module is equipped with motor-driven valve driving current detection circuit and only drives in electronic valve events
Electric current is more than setting electric current, and just triggering uses flexible switch mode.
Further, the trigger condition of the flexible switch mode also can refer to stay open or close shape in motor-driven valve lasting N days
State；N is the integer or decimal greater than 1；Or it points to up to preset time point.
Further, the parameter further includes number of repetition in flexible switch mode, positive and negative actuation time, burst length
Deng can be arranged by input module, can also be directly fixed in control module.
Further, the parameter can be equipped with network interface by motor-driven valve flexible controller, when motor-driven valve flexible controller
After remotely connecting with remote computer, above-mentioned parameter can be set on computers.
Further, the motor-driven valve flexible controller be a kind of temperature control terminal, the temperature control terminal include control module and
It is attached thereto display screen, output module and input module；Output module connects the motor-driven valve and blower of air conditioning terminal, input module
The real time temperature at scene can be detected for parameter or instruction, including key (i.e. physical button) or touch screen to be arranged including key
The temperature sensor of value；The display screen for showing status data, including current temperature value, setting temperature, switch state, when
Preceding operating mode etc.；The control module has timer and clock, can detect and record the operating status of motor-driven valve；
It is generally used for the tail-end blower fan coil pipe, new blower, furred ceiling wind cabinet, also referred to as temperature control panel of central air-conditioning.Such as motor-driven valve
It applies on fan coil, motor-driven valve is connected with air conditioning terminal by water pipe.Since indoor air temperature inertia is big, motor-driven valve increases
Add more than ten seconds actuation times at all to will not influence air-conditioning effect.
Further, the input module is the touch screen of key and display screen unification.
Flexible parameter is simultaneously further set by the combination or long-pressing key, entrance of multiple existing keys on input module.
Motor-driven valve flexibility movement setting function operates with for manager, and common air-conditioning user does not need using by above-mentioned various
The combination button of mode operates, and common air-conditioning user had not only been avoided arbitrarily to enter, but also not will increase daily air-conditioning and use operation
Complexity.
Further, there are also nonvolatile memories；Flexible parameter storage is in the nonvolatile memory.
Further, the input module is equipped with network interface, sets flexible parameter by computer remote.
In addition, the temperature control panel also has self-cleaning function.
The input module can set the self-cleaning parameter of motor-driven valve, and self-cleaning parameter includes self-cleaning movement setting and starts self-cleaning item
Part setting；After the condition meets, the self-cleaning movement of motor-driven valve is triggered and completed；There are also nonvolatile memories；Self-cleaning ginseng
Number storage is in the nonvolatile memory.
After the condition meets, starting motor-driven valve automatically cleaning movement；The motor-driven valve automatically cleaning movement, refers to short
It allows motor-driven valve to open and close repeatedly in time, allows the upper and lower or rotary motion of spool, the automatic dirt for removing spool contact surface
Dirt prevents motor-driven valve stationary for a long time, and the impurity in pipeline is excessive in spool face deposition, and makes spool jam or increase
The resistance of valve core movement；It is allowed inside motor-driven valve simultaneously, such as spring, rubber parts machine components, it will not be because remaining turned-off for a long time
Or the state opened, and generate and ossify, keep its flexibility；The movement of motor-driven valve automatically cleaning is set in control centre or controlling terminal
It sets.
The condition refers to that motor-driven valve continues all to stay open for N days or closed state；N is the integer or decimal greater than 1, such as
In season in spring and autumn, central air conditioner system and motor-driven valve continuous several months all in closed state, if N was set as 15 days, every 15 days
Automatic starting is primary.
Or the condition refers to the time point for reaching predetermined period, such as monthly No. 1 12 points start automatically, no matter at this time
Whether air conditioning terminal is running, and all starts the self-cleaning movement of motor-driven valve；Since self-cleaning actuation time is very short, even if air conditioning terminal exists
Operation can almost ignore room conditioning influence.
Or the condition refers to air conditioning terminal after periodic end of run, air conditioning terminal is in idle a certain
Time point starting, such as 6 points of every afternoon, after operation of air conditioner terminates shutdown, starts the self-cleaning movement of motor-driven valve.
There is periodic motor-driven valve automatically cleaning to act by this, the reliability of motor-driven valve can be greatly improved.
Further, after the motor-driven valve automatically cleaning movement refers to that automatic electric valve is switched even-times, original state is then returned to
State, the state of motor-driven valve is closed from reaching, or once to switch from closing to opening, specifically may is that motor-driven valve is opened or closed t1
Second, it turns off or opens t2 seconds, repeat M times, can also specifically set t1, t2 and M value.
Further, the parameter setting of the condition is completed on temperature control panel by manual key.
Further, key starting (or triggering) condition by being independently arranged on temperature control panel.
Further, pass through the parameter setting for being combined into the condition of existing keys multiple on temperature control panel；Or it is logical
The long-pressing for crossing existing key on input module enters the parameter setting of the condition.
Further, when whole system has large number of motor-driven valve, to avoid multiple motor-driven valve simultaneously operations from causing pipe
The mutation of road flow, on startup between it is upper increase random parameter S, i.e., the S time that is delayed again after the default starting time reaches just starts
The automatically cleaning of motor-driven valve acts.Specifically, random parameter is S1 and S2, if being in close state before motor-driven valve is self-cleaning, i.e., pre-
If the S1 time that is delayed again after the arrival of starting time just starts the self-cleaning movement of motor-driven valve, if being in open shape before motor-driven valve is self-cleaning
State, i.e., the S2 time that is delayed again after the default starting time reaches just start the self-cleaning movement of motor-driven valve.
Further, when motor-driven valve automatically cleaning starts the water circulating pump of fan coil system simultaneously.If water pump is transported in short-term
Row will not cause other adverse effects to system, and the spool of motor-driven valve is rinsed by water flow, can play better self-cleaning effect.
This allows water to flow at spool while spool switchs repeatedly, can wash away the dirt at spool faster.
Further, input module is equipped with network interface, and self-cleaning parameter is arranged by computer remote control.
Further, temperature control panel can control blower start and stop and revolving speed, and can be arranged and detect room temperature, and pass through electricity
The switch control room temperature of dynamic valve.
Further, flexible switch mode is also used when motor-driven valve automatically cleaning.
Since indoor air temperature inertia is big, the actuation time that motor-driven valve increases by more than ten seconds at all will not influence air-conditioning effect
Fruit.
About the self-cleaning supplementary explanation of motor-driven valve:
1) it after remaining off within .N days, automatically opens t1 seconds, turns off t2 seconds, repeat M times, be restored to former closing later
State；
2) it after being kept open within .N days, is automatically closed t1 seconds, then opens t2 seconds, repeat M times, be restored to former opening later
State.
Motor-driven valve automatically cleaning is applied in central air conditioner end air machine coil pipe, since self-cleaning cycle period is longer, one
As N value be 7-30 days, self-cleaning number M be 3-8 times, motor-driven valve power generally only 4-5w, the time of perseveration is less than one point
Clock, the energy consumption that motor-driven valve moves from the point of view of whole year can almost be ignored.Even if in addition in winter or summer air-conditioning use season, it is this
Of short duration valve switch, the influence to room conditioning effect also can almost be ignored.Either air-conditioning season or non-empty in this way
Adjust season, all will not because in pipeline water for a long time be in static, in spool face dirt deposits.
But if motor-driven valve is applied in certain special circumstances, and motor-driven valve automatically cleaning influences whether the peace of installation electric valve system
Row for the national games can increase the chain program of one of safeguard protection, just start automatically cleaning when only the chain program allows.
In addition, temperature control panel also has temperature lock function.
Input module is configured to setting control model (being specifically used for setting refrigeration, heating, air supply pattern), sets mesh
The lock value of temperature value (wishing which temperature interior maintains) and set temperature is marked, lock value is that locking is freezed most
Low value or locking heating peak；
In cooling mode, when target temperature value is set, if control module detects that the target temperature of setting reaches lock
After customizing cold minimum, control module is no longer responded to setting target temperature value is further decreased；It at this time can be on a display screen
Provide prompt；
In a heating mode, when target temperature value is set, if control module detects that the target temperature value of setting reaches
After locking heating peak, control module no longer responds the further setting target temperature value that increases；
Alternatively at: when user adjusts set temperature in cooling mode, set temperature reach locking refrigeration it is minimum
It is no longer reduced after value；After manager locks heating peak under temperature lock function, user adjusts set in a heating mode
When determining temperature, set temperature no longer rises after reaching locking heating peak.
To prevent user by the too low or excessively high of temperature setting on the internal processes of temperature control panel.
So that locking refrigeration minimum is equal to or higher than the lower limit value；Locking heating peak is equal to or less than the upper limit
