Description

A kind of self-cleaning controlling terminal of motor-driven valve
Technical field
The invention belongs to valve control fields, are related to a kind of self-cleaning controlling terminal of motor-driven valve.
Background technique
Fan coil is the tail end air conditioner equipment of central air conditioner system, is typically mounted in indoor suspended ceiling layer, with central hollow Adjusting system is connected by pipeline, and cold/hot water delivers air to room by air cooling-down or heating, then by blower by coil pipe Between;Usual every Fans coil pipe matches a motor-driven valve, and manipulates air-conditioning by indoor user by a temperature control panel.
Motor-driven valve is the temperature controlled critical component of room conditioning, is mounted on the water inlet pipe of fan coil, 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, or changes directly replacement motor-driven valve, and hundreds and thousands of electronic Valve is all mounted in indoor suspended ceiling layer, repairs extremely difficult, and its higher cost;And often also subject in pipeline in valve Higher hydraulic pressure, valve body appearance there are also insulating sponge, when maintenance do not pay attention to slightly will leak, become the entire central hollow of puzzlement Adjust the problem of 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: motor-driven valve quality itself is only focused on as valve manufacturer, such as water pressure resistance performance, Electric Actuator Electronic original part reliability, valve body structure intensity etc.;It is usually all to increase valve body driving to solve the problems, such as that it is stuck that valve is easy The power of 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.
2) controller: motor-driven valve controlling terminal is generally the temperature control panel of fan coil, is electrically connected, passes through with motor-driven valve The temperature control logic control motor-driven valve of temperature control panel opens and closes, and existing temperature control panel is only room conditioning user service, meets The comfortable some requirements of its easy to operate, beautiful, temperature control, so temperature control panel producer also has no reason to consider motor-driven valve at all It is stuck or the problem of fit badly.
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 valve cleaning apparatus for self be designed, on the basis for not increasing hardware On, it not only 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 self-cleaning controlling terminal of motor-driven valve, the self-cleaning controls of the motor-driven valve Terminal does not have to dismantle valve body, easy to implement, can improve the reliability of motor-driven valve.
The technical solution of invention is as follows:
A kind of self-cleaning controlling terminal of motor-driven valve, including control module, display screen and input module;Display screen and input module It is connected with control module;The self-cleaning controlling terminal of motor-driven valve is equipped with the output terminal for controlling motor-driven valve;Connect with motor-driven valve It connects, can control the switch of motor-driven valve, input module is for inputting instruction or parameter;
The self-cleaning controlling terminal of motor-driven valve has the self-cleaning program of motor-driven valve, and can act to self-cleaning trigger condition and automatically cleaning It is set;When self-cleaning condition meets, the self-cleaning controlling terminal driving motor-driven valve of motor-driven valve makes automatically cleaning movement.
Further, the self-cleaning trigger condition refers to that motor-driven valve continues all to stay open for N days or closed state, wherein electronic The state of valve is detected by the self-cleaning controlling terminal of motor-driven valve;N is the integer or decimal greater than 1, such as in season in spring and autumn, central air-conditioning system System and motor-driven valve continuous several months are dynamic every automatically cleaning of 15 days automatic triggers if N is set as 15 days all in closed state Make.
Further, the self-cleaning trigger condition refers to the time point for reaching predetermined period, and such as monthly No. 1 12 points are opened automatically It is dynamic, no matter whether air conditioning terminal is running at this time, all automatically cleaning movements of triggering dynamoelectric water valve;Very due to automatically cleaning actuation time It is short, less than one minute, even if air conditioning terminal is being run, room conditioning influence can almost be ignored.
Further, self-cleaning trigger condition described in person refers to air conditioning terminal after periodic end of run, at air conditioning terminal After air-conditioning not running terminates shutdown, oneself of dynamoelectric water valve is triggered such as 6 points of every afternoon in idle sometime point starting Cleaning action;
The condition for judging motor-driven valve triggering automatically cleaning movement, usually by the self-cleaning controlling terminal of motor-driven valve or remote control center Automatic detection has periodic motor-driven valve automatically cleaning to act, the reliability of motor-driven valve can be greatly improved by this.
Further, motor-driven valve automatically cleaning movement refers to that the state of motor-driven valve is closed from reaching, or from closing to opening is primary Switching, after being switched even-times, then returns to original state;By allowing motor-driven valve to open and close repeatedly in the short time, spool is allowed Upper and lower or rotary motion, the automatic dirt for removing spool contact surface prevents motor-driven valve stationary for a long time, in pipeline Impurity 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 bullet The machine components such as spring, rubber parts will not generate and ossify because of the state that remains turned-off or open for a long time, keep its flexibility.
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, 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 automatically cleaning movement of motor-driven valve, opened if being in front of 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 automatically cleaning movement of motor-driven valve.
Further, the self-cleaning controlling terminal of the motor-driven valve is equipped with linkage signal output terminal, when motor-driven valve is water valve, electricity Dynamic valve is self-cleaning while starting water pump.If water pump makees operation in short-term will not cause other adverse effects to system, and pass through water flow The spool for rinsing motor-driven valve, can play better self-cleaning effect.In addition, motor-driven valve is self-cleaning to may not only be applied to air-conditioning water route system System similarly applies also for other using the industry of electrical fluid valve, such as electric-air valve, Electric air valve, electro-hydraulic valve, electronic Steam valve etc. allows fluid to flow at spool while spool switchs repeatedly, can wash away the dirt at spool faster Dirt.
Therefore when motor-driven valve is air valve, motor-driven valve automatically cleaning while booster air pump;It is electronic when motor-driven valve is oil path valve Valve is self-cleaning while starting oil pump;When motor-driven valve is air-valve, motor-driven valve automatically cleaning starts blower simultaneously;When motor-driven valve is steam valve When, motor-driven valve is self-cleaning to open simultaneously vapour source.
The supplementary explanation self-cleaning about 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 is self-cleaning to be applied in central air conditioner end air machine coil pipe, since self-cleaning cycle period is longer, General N value It is 7-30 days, self-cleaning number M is 3-8 times, and the time of motor-driven valve perseveration, motor-driven valve moved from the point of view of whole year less than one minute Energy consumption can almost be ignored.Even if in addition in winter or summer air-conditioning use season, it is this since indoor air temperature inertia is big 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.
If but motor-driven valve is applied in certain special circumstances, the self-cleaning safety for influencing whether installation electric valve system of motor-driven valve Operation, can increase the chain condition of one of safeguard protection, just start automatically cleaning when only the chain condition sequence allows.
Further, the self-cleaning controlling terminal of the motor-driven valve is a kind of temperature control terminal, the temperature control terminal include control module with 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, inputs mould Block includes key, for parameter or instruction to be arranged;Input module can set self-cleaning trigger condition and automatically cleaning movement;Control module In have timer and clock;It is generally used for the tail-end blower fan coil pipe, new blower, furred ceiling wind cabinet, also referred to as temperature control face of central air-conditioning Plate.
Further, the touch screen that the key and display screen are integrated.
Further, the combination by existing keys multiple on input module or long-pressing key, into the self-cleaning triggering item The setting of part.
Further, by the locking key being separately provided on input module, into the setting of the self-cleaning trigger condition.
Further, the input module is equipped with network interface, sets self-cleaning trigger condition and automatically cleaning by computer remote Movement.
Control module is connected with nonvolatile memory;Self-cleaning parameter storage can store in the nonvolatile memory.
In addition, the self-cleaning controlling terminal of motor-driven valve includes flexible switch mode in driving motor-driven valve switch motion.
The movement of motor-driven valve is other than conventional directly switch, and there are also flexible switch modes;That is the opening of motor-driven valve is adopted It is opened with flexible way or the closing of motor-driven valve is closed using flexible way or the opening and closing of motor-driven valve all use flexibility Mode;Or each movement of motor-driven valve work all uses flexible switch mode, or only uses in the specific partial act of motor-driven valve Flexible switch mode.
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.
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 Value.
Locking key is separately provided.
Locking key uses built-in key, such as key to be equipped with cover board, digs energy depresses button after cover board.
Locking key is by existing multiple keys by the way that realization (such as while by mode key and increasing key) is applied in combination.
Temperature control panel and Master Control Center communicate to connect, and Master Control Center is enabled to lock all temperature control panel bound temperature Degree.
The utility model has the advantages that
The self-cleaning controlling terminal of motor-driven valve of the invention (or controlling terminal, control panel, temperature control panel etc.) has following Feature:
(1) have on mode basis in temperature control panel, increase the self-cleaning maintenance function of motor-driven valve, utilize existing temperature control panel The programmable function of internal computer opens and closes motor-driven valve by temperature control panel automated periodic, by the movement of spool, no Spool face dirt is just disposed automatically with valve body is dismantled, and form spool face will not at it hard because stationary for a long time Hard deposit keeps its flexibility, to reduce the failure rate of motor-driven valve!
(2) motor-driven valve flexible switch: existing temperature control panel control motor-driven valve is all directly to open or close, even if spool portion There is foreign matter in position, also still will continue to open or close, often makes spool jam, motor in motor-driven valve is caused to burn out.The present invention exists Motor-driven valve flexible switch mode is used on temperature control panel, if first motor-driven valve is allowed to open, spool is positive when motor-driven valve is by closing to when opening A fragment position is moved, then motor-driven valve is allowed to close, one fragment position of spool counter motion, repeated several times, then fully open motor-driven valve. In this way by perseveration several times, allows the foreign matter at spool to be easy to loosen, reduce spool jam, motor-driven valve motor internal is burnt out It may.
(3) have on mode basis in temperature control panel, refrigeration minimum can be locked respectively and heat peak by increasing Temperature lock function;When being locked under temperature lock function after freezing minimum, then adjusting set temperature in cooling mode, if Determine no longer to reduce after temperature reaches locking refrigeration minimum;Under temperature lock function after locking heating peak, then heating When adjusting set temperature under mode, set temperature no longer rises after reaching locking heating peak.
And above-mentioned 3 functions, all only it can be achieved with by modifying the control software of temperature control panel!Make it have pole Big cost performance.The invention is:
Valve itself can not only be jumped out, the valve routine application model also jumped out runs to maintenance management from equipment, comprehensive Multi-party factor considers a problem, it more difficult to which what is obtained is while can not increase any artificial and material cost basis using existing resource Upper solution motor-driven valve is easy stuck historical difficulty!
