Abstract
The present invention is an automatic constant temperature bleeder of water heater.According to principle of expanding with heat and contracting with cold, rely on water heater temperature's cold and hot variation, the automatic on-off valve is emitted the hot water of required fixed temperature.Open the Draw off valve effect because this device has constant temperature,, need not resupply water and monitoring water temperature so feed-water inlet is opened.This device has the advantages that to alleviate labor service, simple in structure, convenient and reliable, highly sensitive, the noise free of work, energy saving.
Description
The invention belongs to the water heater constant temperature delivery water device.
Water heater feedwater, monitor temperature in the heating process reaches and in time discharges water after temperature required, all needs usually manually to carry out.
At present, to the control of water heater feedwater and constant temperature delivery water, generally adopt hand sluice valve.Adopt solenoid valve as constant temperature delivery water, then need electric energy, noise is arranged again, and complex structure, cost an arm and a leg.
As far as our knowledge goes, purpose of the present invention is to create a kind of institute as required fixed temperature and discharges water automatically, and device that again can self water feeding both can alleviate labor service, but energy saving again, and noise free, simple in structure, reliable working performance, with low cost.
According to above-mentioned purpose, the present invention proposes a kind of according to principle of expanding with heat and contracting with cold, and the device of energy automatic constant temperature delivery water has the function that discharges water automatically simultaneously.
The present invention is applicable to the constant temperature delivery water usefulness of any water heater, now illustrates that with the example that is installed on solar water heater its structure is seen figure one.
(1) is chewed in hot water output, and its aperture is φ 8mm, greater than the diameter of fore-set (12), porous disc (3), (8) water supply circulation effect is arranged in the valve pocket (2), and the logical area of its current is 1.3CM
2, the material of spring (4) should be selected beryllium bronze for use, and its elastic force is than the big 0.2-0.3 kilogram of thrust (after the precompression) of the tap water that is closed.The thrust of tap water is calculated by the middle footpath of zero shape rubber seal ring (10).The about 53mm of length of spring precompression stop collar (5), internal diameter is φ 17mm, external diameter is φ 20mm.The diameter of spring base (6) is φ 6mm, and internal thread is M3.Pad (7) is the pad of spring base (6).The internal diameter of the end face zero shape annular groove of spool (9) is φ 5.8
+ 0.05 0Mm, external diameter are φ 9.5-0.05mm.The degree of depth is 1.5
+ 0.05 0Mm.The nominal size of zero shape rubber seal ring (10) is 10 * 1.9mm, and its hardness is HS70.Constant temperature weep hole (11) is totally 6 holes, and its aperture is φ 2.5mm, and Kong Zaiyuan evenly distributed on week, and the center line in hole and the angle of end face are 20 °.Fore-set (12) one ends are big, and an end is little, and its big end diameter is φ 6mm, length 7.5mm, and a little end diameter is φ 3mm, length is 9mm.Bellows (13) shape is seen figure three, and its major diameter is φ 5.68mm, and minor diameter is φ 1.6mm, and length is 57mm, and its material is a tin bronze.The aperture in hydro-cushion hole (14) is φ 2mm, and totally 4 holes are axially uniform.Corrugated header (15) working medium is injected and is chewed (17), the no specific (special) requirements of protective cap (20), and its size quite gets final product.Working medium (16) is preferably selected purity alcohol for use.Preferably the material with valve pocket (2) is identical for the material of the nut (18) that cooperates with water heater, so that weld or bonding.Working medium tube (19) is a book wall seamless steel pipe, and internal diameter is about φ 23mm, and external diameter is about φ 25mm, and length is about 1025mm.Porous disc (3), (8), spring precompression stop collar (5), spool (9) and fore-set (12) all adopt ABS plastic to make material.
The welding particular importance of this device, the technology strictness.If any minute leakage, then move malfunctioning.Bellows (13) and corrugated header (15) are chewed (17) with the working medium injection and also can be used the duration and degree of heating brazing with high frequency hydrogen protection welding, corrugated header (15), working medium tube (19).After welding is finished, all need once with the helium mass spectrometer leak detector leak detection.After whole leak detections are errorless, just can carry out constant temperature.
The method of constant temperature is that the full device that installs is inserted (working medium is injected and chewed (17) upwards) among the hot water barrel, and the hot water face is as the criterion to flood working medium tube (19).Working medium (16) expanded by heating in the hot water barrel is chewed (17) from the working medium injection and is overflowed.When treating the no spillover of working medium (16), use scolding tin sealing uropore (soldering envelope point (21)) immediately.By this method constant temperature, the water temperature among the hot water barrel should be than desiring low 2 ℃ of fixed temperature.For example, the average water temperature of desiring water heater is discharged water is 49.5 ℃, and then the water temperature among the hot water barrel should be 47.5 ℃.
This device is first to be installed when starting, must export in the hole of chewing (1) from hot water with private key (shape is seen figure two) and insert, be threaded onto in the termination screw of spring base (6), draw back spool (9), making air in the water heater all chew (1) from hot water output drains, till having tap water to discharge, just can unload key.
The operation of this device is simpler, and when water temperature raise in the water heater, the temperature of working medium (16) increased.Working medium (16) expanded after water temperature was higher than institute's fixed temperature, promoted bellows (13) elongation, backed down spool (9) thereby promote fore-set (12), and tap water (is heading straight for) hydraulic pressure that inserts water heater ejects hot water.Water temperature descends in the water heater, and working medium (16) temperature descends bellows contract thereupon.Spring (4) promotes spool (9) and resets, airtight tap hole (11), and so far discharging water also stops.Because water heater and this device all are in air-tight state, the tap water feed-water inlet is opened, so automatic water supplement at any time.
The temperature of water that this device is emitted is decided with constant temperature time institute fixed temperature.Adopt metallic material to make as whole devices, working medium (16) is used oils instead, and then institute's fixed temperature can be more than ambient temperature to 100 ℃.Make with ABS plastic as some member, then institute's fixed temperature can be below ambient temperature to 100 ℃.
This device walk-through water temperature and whole draining temperature have the difference about 4 ℃.As the balanced consistent water temperature of needs, difference is reduced in 1 ℃, the diameter of working medium tube can be reduced, radical increases.
This device walk-through mixes with whole draining, its average water temperature substantially constant indefinite (difference is in 1 ℃).
This device is discharged the hot water amount and is become with heating power.
The present invention is because according to principle of expanding with heat and contracting with cold, rely on water heater temperature's cold and hot variation, come opening/shutting valve to emit the hot water of required fixed temperature, so no longer need other energy to come opening/shutting valve and water supply and drainage, make things convenient for the management and the use of water heater, had characteristics such as simple in structure, reliable operation, energy saving, noise free.As it is all very convenient to be used for electric water heater, far infrared water heater etc., especially cooperates automatic control switch, more apparent its advantage.On solar water heater, it is installed, does not need power consumption basically.
