The utility model final controlling element is installed in heat supplying pipeline, carries out and connects or the mobile action of blocking-up pipeline inner fluid.Whether circuit is carried out in control 1 and is provided with out valve optoelectronic switch 15 and pass valve optoelectronic switch 18, by shading rotating disk 14, drives light barriers 19, for detection of electric machine rotation stroke, put in place, has reliability by force and long lifetime feature.
Working procedure and the principle of the utility model final controlling element is (referring to Fig. 1-3), circuit in this final controlling element is carried out control 1 and is received by pilot 17 control signal that outside on-off controller sends, by circuit control panel 16, control the driving wheel 12 in drive motor 11 driven gear casees 13, valve rod 21 is rotated, now gear-box 13 plays the effect of deceleration and reinforcement, and valve rod 21 runnings realize the rotation of spool 24 and open or close.
The utility model final controlling element is peculiar exclusive Functional Design and the manufacture of make-and-break time method of areas heat metering device, different from common electric ball valve (the on-off controller final controlling element using at present), the main control parameters of its design is working life (keying number of times), rather than the sealing of water (flow) direction.The utility model final controlling element is when the mfg. moulding die process parameter of design valve body 2, rationally adjust and improve, to control the spherical cambered surface sealing layer 23 of assembling rear valve body 2 inside and the seal contact pressure between spool 24, suitably reduce the sealing of water (flow) direction, making spool 24 is water at working medium, rotation starting torque under 1.6MP working pressure is less than 0.1Nm, guarantees the drive motor 11 of circuit execution control 1 interior installing and is greater than 100,000 times the working life of gear-box 13 internal tooth wheels.Increase the number of plies of valve rod 21 axial seal cushion rubbers 22 simultaneously, by the individual layer sealing of existing common electric ball valve, change multi-layer sealed (more than 2 layers) into, greatly improve the axial sealing reliability of valve rod 21, guarantees to open and close for 100,000 times in the life-spans without leakage.The bottom of valve body 2 is provided with temperature measuring hole 25, by being connected with probe plug 32 couplings, temperature probe 31 is embedded in valve body 2, temperature measuring wire 33 is connected with outside on-off controller temperature measurement circuit, thereby make valve body 2 there is the effect of Temp. measuring ball valve, to reach the object of measuring hot user's water temperature (supplying water or backwater).Valve body 2 two ends are provided with outside thread 26, for the meter connector of connection standard, are convenient to installation and removal and safeguard.
The circuit of the utility model final controlling element is carried out in control 1 and is adopted and drive valve optoelectronic switch 15 and close the traditional limit switch of valve optoelectronic switch 18 replacement, its working principle is to the blocking-up of infrared emission light and conducting, the judgement that utilizes infrared receiving tube sensitization conducting and black out cut-off characteristics to realize out and close.For ease of explanation optoelectronic switch working procedure (referring to Fig. 4), suppose that working as early gate is closed condition, shading rotating disk 14 is rotated counterclockwise 45 °, is in the groove that closes valve optoelectronic switch 18.When executive mode is when driving valve, pilot 17 transmits the specified threshold voltage signal of opening, control circuit board 16 receives out threshold voltage signal, open 15 conductings of valve optoelectronic switch, drive motor 11 energising entrys into service, by the interior driving wheel 12 of gear-box 13, slow down to increase and turn round counterclockwise band ovable valve stem 21 and shading rotating disk 14, through approximately 12 second cycle time, shading rotating disk 14 is rotated counterclockwise 90 ° of light barriers 19 and goes to out in the groove of valve optoelectronic switch 15, open 15 cut-offs of valve optoelectronic switch, drive motor 11 power-off, shut down, and now valve is opening state; When the specified pass of given pilot 17 threshold voltage signal, control circuit board 16 receives and closes threshold voltage signal, close 18 conductings of valve optoelectronic switch, drive motor 11 energising entrys into service, by the interior driving wheel 12 of gear-box 13, slow down to increase and turn round, be with counterclockwise ovable valve stem 21 and shading rotating disk 14, through approximately 12 second cycle time, shading rotating disk 14 is rotated counterclockwise 90 °, light barrier 19 goes in the groove that closes valve optoelectronic switch 18, close 18 cut-offs of valve optoelectronic switch, drive motor 11 power-off shut down, and now valve is closed condition.In present embodiment, drive valve optoelectronic switch 15 and close valve optoelectronic switch 18, circular path along light barrier 19 on shading rotating disk 14 is 90 ° of angles designs, and two light barriers 19 of shading rotating disk 14, by 180 ° of designs relatively, complete thus every 90 ° of rotations and open valve and the positioning states that closes valve.In operation process, the electric spark ablation that the semiconductor limit switch of machinery-free contact can avoid contact mechanical wear and contact break-make to produce, makes this photoelectricity project organization have that running noise is little, the life-span long, high reliability.In theory, the life-span of optoelectronic switch is restriction not, much larger than 100,000 times.
The utility model final controlling element belongs to a kind of make-and-break time method of areas heat metering device critical piece, valve body 2 can directly be equipped with temperature transducer by temperature measuring hole 25, being about to temperature probe 31 stretches in valve body 2 by temperature measuring hole 25, probe plug 32 is connected with the internal thread of temperature measuring hole 25, temperature measuring wire 33 is connected with outside on-off controller temperature measurement circuit, does not need separately to join Temp. measuring ball valve the temperature sensor probe of measuring hot user's water temperature is installed.What the utility model adopted drives valve optoelectronic switch 15 and closes valve optoelectronic switch 18, comprises and is structurally separated from each other and transmitter and receiver that optical axis is staggered relatively, and the light that transmitter sends directly enters receiver.When light barrier 19 is through between the two and during blocking-up light, optoelectronic switch will produce signal.The more traditional conventional mechanical limit switch of which (displacement switch) control mode is more accurate, and reliability also greatly strengthens.Untouched control makes product more durable, increases to a great extent working life.Valve body 2 also improves in material and structure in addition, by changing valve rod 21 axial seals, design, increase the object that O-ring seal 22 thickness and the number of plies reach valve rod 21 axial leakproofs, while is in view of the monopoly of this final controlling element application, can in water (flow) direction sealing, suitably lower the requirement, adjust and control the assembling contact between spool 24 and spherical cambered surface sealing layer 23, to reduce the contact wear of spool 24 and spherical cambered surface sealing layer 23, reduce the driving torque that spool 24 rotates, extend the life-span of drive motor 11 and gear-box 13 internal tooth wheels.
The utility model final controlling element is to calculate over 100,000 times to open and close number of times in working life under medium, 1.6MPa working pressure at water, its operational safety in make-and-break time method of areas heat metering device can be fully guaranteed, and the temperature measuring hole 25 of innovative design, can save the supporting Temp. measuring ball valve of on-off controller, effectively reduce costs and volume; The standard external structure that valve body 2 two ends of innovative design can be connected with meter connector, greatly facilitates the maintenance and repair of project installation construction and on-off controller final controlling element.
The utility model is not addressed part and is applicable to prior art.
