Description
The cold pulse modulating water mixing valve that patent of the present invention provides is a kind of fluid control device, belongs to valve class technical field.
Mixed water valve has many patents.With the Chinese patent is example, and it is cold that patent CN87208673U system with thermo-bimetal is that heat responsive element is regulated simultaneously, and hot water supply flow is than regulating bath water temperature automatically.Patent CN2112735U has done the binomial improvement on above-mentioned patent basis: (1) with in fill low boiling working fluid bellows heat responsive element and replace the thermo-bimetal; (2) increased flow control device: adopt a kind of in, outer dual sleeve, inner sleeve is made axial displacement and is changed cold the other way around under the bellows heat responsive element drives, hot water water supply import flow area is so as to temperature control, and outer sleeve rotates under the Flow-rate adjustment knob drives and regulates output bath water flow.For this reason, this patent has adopted dual (temperature regulation and Flow-rate adjustment) O type cushion rubber movable sealing.
Mention and mix the water heat control valve, people often think very simply: cold water is oozed to be incorporated into hot water just do not obtain warm water! Add various heat responsive elements and just be not easy to realize the adjusting of mixed water temperature? Actual is not so simple, certainly will influence water-mixing temperature control because cold water and pressure of hot water often have than big difference.Theoretical and experience shows that all then both must be in a kind of extremely unsettled transient equiliblium if the fluid of two kinds of different pressures is fed container straight simultaneously, is difficult to evenly mix; And evenly do not mix is that impossible realization is thermoregulator, also can produce bigger temperature fluctuation even regulate.The inventor thinks that this is a great problem that civilian mixed water valve must solve.Second difficult problem is to mix water valve must adapt to different regions cold water hydraulic pressure and may have very big-difference and the frequent complex situations that change of hydraulic pressure, and this existing patent is not had Corresponding Countermeasures; The 3rd difficult problem then is that modulating valve is intrinsic, promptly regulate usually to relate to movable sealing, and movable sealing is definitely not accomplish ne-leakage in theory.Aforementioned patent exactly relates to movable sealing, and is that (temperature adjustment, accent stream) is dual.
The objective of the invention is to be non-electric heating class domestic hot water device, cold fully, the hotel of hot water piping, bathhouse and residence toilet provide washes one's face and rinses one's mouth and the mixed water valve of shower, this valve is heat supply coolant-temperature gage wide variation outside, continuously smooth is regulated water temperature under the service condition of cold water hydraulic pressure large-scope change, and flow and water temperature are coordinated mutually and not have leakage non-maintaining.
Below be design main points of the present invention:
For solving the coordination problem of hot water or cold water's hydraulic pressure, with two valves---cryogen stop valve and high temperature fluid temperature-sensing valve synthesize a mixed water valve, the shared valve seat of two valves.Low temperature valve is done spool (valve rod) with a bellows that includes stage clip, and the spool of high-temperature valve (valve rod) has the bellows (being called for short the temperature-sensitive bellows) of temperature sensing medium in being.The elastic force that presets of the interior stage clip of pressure medium and low temperature valve bellows is mechanical equilibrium in the temperature-sensitive bellows.Thereby when the not high pressure medium of hot water temperature that feeds high-temperature valve during less than stage clip elastic force, low temperature valve bellows spool will be pressed on the shared valve seat, and cold water is closed in the low temperature valve pocket, and can not mix mutually with hot water.When the hot water water temperature is higher when surpassing setting temperature, pressure medium is just backed down by the feeler lever on the high-temperature valve temperature-sensitive bellows greater than stage clip elastic force, low temperature valve spool, and it is mixed mutually with hot water that cold water enters high-temperature valve.Low temperature valve is to be designed to stop valve, it has only two kinds of working staties, open (standard-sized sheet), close (full cut-off), the valve opening with shared valve seat is designed to seedpod of the lotus head again, and wherein the total circulation area of sieve aperture (spilled water hole) is less than the average flow cross section of low temperature valve, therefore low temperature valve is in case backed down, cold water will be injected high-temperature valve with high speed thread bundle form and very certainly mix mutually with hot water, and water temperature is descended rapidly, and low temperature valve immediately cuts out again; Be that low temperature valve is with on-off mode work.Mixing water temperature adjustment process can summarize and be modeled as: flow pulse with the thin cold water of high speed quality hot water in the mixed water cavity of cold water is modulated.So just solved the direct problem of mixing hot water or cold water's hydraulic pressure imbalance (inharmonious) of being run into of hot and cold water.Because the mixed water valve of the utility model design has above working principle and the characteristics event claims that this patent valve is a cold pulse modulating water mixing valve, be called for short and mix water valve.
In addition, because whole mixed water management is with cooling pulse current hot water to be modulated, its result must be: for same flow of hot water, the hot water temperature is the temperature upper limit of output mixing water, hot water flow then is the lower limit of output water flow, temperature and the flow of output mixing water are contravariant, promptly between the upper and lower limit of aforesaid temperature and flow the water temperature height then flow is little, water temperature hangs down that then flow is big.The mutual coordination of this temperature and flow had both met the water custom, also met the principle of saving water and energy.In view of above-mentioned, consider cost and price factor again as civilian goods, consider the simplicity of technological innovation, this patent valve is not established flow regulator in addition.
The present invention seeks to realize by following technical measures:
Mix water valve by the cryogen stop valve, high temperature fluid temperature-sensing valve and mixed water mantle combine.Low temperature valve and high-temperature valve have a valve seat.
Can the conflict bellows of valve seat of bottom is set in the valve pocket of cryogen stop valve, stage clip is housed in the bellows, stage clip is borrowed the pressure of band knob to adjust screw rod and is regulated and preset elastic force.The bellows of temperature sensing medium is arranged in being provided with in the high temperature valve pocket, establish feeler lever on the temperature-sensitive bellows, feeler lever can pass the shared valve seat of high and low temperature valve and touch at the bottom of the low temperature valve bellows.On the shared valve seat of high and low temperature valve sieve aperture is set, total circulation area of this sieve aperture is less than the average flow cross section of low temperature valve.Be provided with mixed water mantle in the high-temperature valve, the zone constitutes mixed water cavity between tube and the temperature-sensitive bellows, and end face has the sluicing gap on the tube.The hot water inlet is opened in the high-temperature valve bottom, and cold water inlet is opened in the low temperature valve sidewall.
Working principle of the present invention is as follows:
When hot water (or having deposited mixing water in the high-temperature valve) temperature not high (being lower than setting temperature) that feeds high-temperature valve thus high-temperature valve in the temperature-sensitive bellows pressure medium less than the low temperature bellows in during by the stage clip elastic force of adjusting knob setting low temperature valve close, cold water can not enter high-temperature valve; When hot water (or having deposited mixing water) water temperature is higher when surpassing setting temperature, pressure medium is greater than stage clip elastic force, low temperature bellows bottom is just backed down by the feeler lever on the high temperature bellows, at this moment just there is one high speed cold water thread to inject high-temperature valve and mixed mutually with hot water (or having deposited mixing water), water temperature descends rapidly under hot water or cold water's strong convection situation, and low temperature valve is closed again.Like this, with the low temperature valve of on-off mode work realize with cold water stream to hot water (or having deposited mixing water) in addition Sampling carry out the flow that coolant controlled has also been controlled output water simultaneously.Rotate the low temperature valve adjusting knob, the stage clip elastic force of low temperature valve and high-temperature valve temperature sensing medium pressure repeat above-mentioned control procedure again under a new mechanical equilibrium, obtain new output water temperature and flow, and because of restricted by the system capacity conservation, water temperature and flow must be contravariant.
In use, this patent valve is connected in series to the hot water pipe, connects a cold water pipeline again and get final product.Experiment shows: at cold water hydraulic pressure is 0.5-3kg/cm
2, the hot water water temperature is under 40-70 ℃ the water and heat provision condition, by the low temperature valve adjusting knob output water temperature is changed at 35-70 ℃ of continuously smooths, and water temperature and flow are contravariant.
Mix water valve by the cryogen stop valve, high temperature fluid temperature-sensing valve and mixed water mantle constitute.
The cryogen stop valve comprises valve body 7, but the bellows 13 of the shared valve seat 9 of pipe end shutoff, and this bellows 13 and gland 14 are injected into one, seal with O type rubber seal 12 between gland 14 and the valve body 7.Stage clip 10 is arranged in the bellows 13, have the pressure of band knob to adjust screw rod 15 on the stage clip 10.There is seedpod of the lotus shape porous sieve aperture 8 at the middle part of shared valve seat 9, above the shared valve seat 9 of high and low temperature valve the O RunddichtringO is set.Low temperature valve valve pocket inwall vertically is provided with spline 11, and spline inner diameter is slightly larger than outside diameter of bel so that the spline inner diameter wall play the guiding role spline then for cold water channel to bellows 13.High-temperature valve hot water inlet 1 is opened in the valve bottom, and high-temperature valve inner corrugated pipe 4 is located on the high-temperature valve valve body 2 bottom bellows guide sleeves 3, and hot water sluicing gap 17 is arranged on this guide sleeve 3.Outside the bellows 4 mixed water mantle 5 is arranged, have sluicing gap 6 on it, mixing water is poured into outlet 16 from top to bottom through sluicing gap 6.Bellows 13 and gland 14 also can adopt another kind of compound mode: the bellows shoulder welds a flange edge 18, and Ge Jia-O RunddichtringO relends gland 14 and screws about flange edge, as shown in Figure 5.
