Description
Technical field
The utility model relates to a kind of valve means, specifically relates to a kind of aqueous vapor linkage valve of gas heater.
Background technology
At present, the aqueous vapor linkage valve of most of gas heaters generally comprises: one by a magnetic valve and air volume regulating valve is formed and gas circuit that communicates with burner and the aqueous vapor linkage of being made up of a water regulating valve and the pressure differential disc that links to each other with microswitch.When opening water valve, utilize intake pressure to back down the depression bar that is connected with microswitch, trigger microswitch, open the safety-valve in the aqueous vapor interstage valve simultaneously.Open when microswitch, impulse generator is started working, and triggers magnetic valve and opens, and the safety-valve that combustion gas is directly passed in the opened aqueous vapor interstage valve enters in the combustion chamber, and igniter begins igniting.The shortcoming of said structure is: be introduced in the combustion chamber because combustion gas takes place easily, just taking place because of firing delay directly causes " detonation " phenomenon will appear in Dian Huo situation.When cutting off the water, in case that the aqueous vapor interstage valve resets is bad, safety-valve just may take place can not closure and microswitch fails to be triggered and produces the signal of cutting out electromagnetic valve of gas circuit, thereby " dry combustion method " phenomenon takes place.
In order to prevent the above-mentioned problem that " detonation " and " dry combustion method " phenomenon may take place, the solution that patent ZL02225039.5 proposes is: also be provided with a little gas circuit in valve chest, also be provided with a magnetic valve on the gas circuit, small fire burner set in this gas circuit and the combustion chamber is connected.Though can reducing " detonation " phenomenon to a certain extent, this scheme takes place, but because it has still structurally adopted the traditional form of " pressure differential disc adds microswitch as pulse signal source ", so when pressure differential disc is pushed, spool is moved, and has backed down the burnt gas valve that originally is used as the second road discharge cock.The magnetic valve that the microswitch action causes impulse generator to trigger respectively on the gas circuit is opened and the igniter igniting.In this technical scheme, originally be used as the burnt gas valve of the second road discharge cock, do not have the important function of discharge cock in fact at all, perform practically no function.And when cutting off the water, in case that the aqueous vapor interstage valve resets is bad, safety-valve just may take place can not closure and microswitch fails to be triggered to produce and cuts out the signal of electromagnetic valve of gas circuit, thereby can not avoid the problem of " dry combustion method ".
In addition, the aqueous vapor interstage valve of the traditional structure of " valve for pressure difference adds microswitch ", volume is big, the microswitch installation difficulty is big, needs veteran professional rely on experience, detect repeatedly the debugging shift fork the location, reset and starting effect.Regular meeting occurs resetting slowly during the mechanical type microswitch, even stuck and cause the shortcoming of water heater " dry combustion method ", and when hydraulic pressure was lower than normal value (0.025 MPa), pressure differential disc can't normally start microswitch, and water heater can't start use.
Certainly, it is to adopt the current magnetic induction switch to be set to control the water heater low voltage starting that improved technical scheme is also arranged, " the non-resistance inductive switch " that provides as patent ZL01247374.X, but this technical scheme just just reduces the improvement of resistance to water-flow aspect to traditional current magnetic induction switch by the way that adds bypass, clearly on water heater, how not use, and when implementing this scheme, need on valve body, punch and be connected and fixed isocon by oxygen welding or with the cored screw that is coated with fluid sealant, more than the operation and difficult quality guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of volume less, compact conformation, and is general supporting easily with present water heater product, can effectively prevent " detonation ", can prevent the safety-type water and gas coupled valve of gas water heater of " dry combustion method " phenomenon again.
In order to achieve the above object, establish in the utility model aqueous vapor interstage valve comprises the little axle of valve hydraulic pressure thrust plate interlock valve chamber, water regulating valve, air volume regulating valve, be used to control magnetic valve, pulse signal generator and the pulse igniter that gas circuit opens and closes, in the inlet channel entrance of this aqueous vapor interstage valve, be provided with a Magnetic Induction switch assembly that opens and closes magnetic valve and pulse igniter shared signal source as gas circuit, this switch assembly is electrically connected with pulse signal generator, and pulse signal generator also is electrically connected with electromagnetic valve of gas circuit and pulse igniter respectively.
Described Magnetic Induction switch assembly comprise a porch that is positioned at upright inlet channel and can be along the inlet channel axially-movable contain the permanent magnet float, one is positioned at the stopping means of this float top and is positioned at inductive switch on the inlet channel outer wall, this inductive switch is corresponding to the position between stopping means and the float, preferably corresponding in stopping means is equivalent to the scope of float height downwards.
The inlet channel inwall at float place has one or more semicircle guiding gutter along water (flow) direction, and also has the oblique guiding gutter of many parallel distributions on the inner ring surface of the porch of inlet channel.
Described water regulating valve is the control valve with three gears, and the hydraulic pressure starting value of these three gears is respectively 0.01～0.02Mpa, 0.02～0.03Mpa and 0.03～0.04Mpa.
After adopting said structure, owing to the triggering signal of electromagnetic valve of gas circuit and the igniter action triggers pulse signal generator by the Magnetic Induction switch comes, move under the pressure of water prior to the interior interstage valve of establishing the little axle of valve hydraulic pressure thrust plate, though so can guarantee it is to have opened the magnetic valve on the gas circuit earlier and begun to light a fire all the time, but the interstage valve as easing valve is always opened at last, like this, interstage valve has just really played the effect of easing valve, thereby in the possibility of fundamentally having stopped generation " detonation " and " dry combustion method ".In addition, the oblique guiding gutter that the water inlet is provided with rotates current, avoids float to be stuck because of impurity in the surface adhesion water; The inlet channel inwall has increased and has crossed the water cross section along the half slot that water (flow) direction has, and has offset the part resistance that current is produced because of float.
The third gear water yield (normal hydraulic pressure starting, low hydraulic pressure starting, the starting of ultralow hydraulic pressure) control valve changes traditional step-less adjustment into three grades of regulative modes that preestablish hydraulic pressure startup value scope, to adapt to each regional hydraulic pressure needs (comprise no running water and use well water place), make things convenient for the user easier when selecting applicable pattern, can effectively prevent maloperation.

The specific embodiment
As shown in Figure 1, the utility model aqueous vapor linkage combination valve assembly comprises valve chest 1, the middle part of housing 1 is provided with the gas outlet 2 towards burner, adjacent in water route and gas circuit in the housing 1 is provided with the aqueous vapor linkage, this device comprises the valve spool 18 that is positioned at air valve, the valve that is positioned at water valve little axle hydraulic pressure thrust plate 16 and barrier film 14, links to each other with the little axle 17 of valve between valve spool 18 and the hydraulic pressure thrust plate 16.In the gas circuit of housing 1, be provided with a magnetic valve 3.
Fig. 3 is the schematic diagram of inlet channel 9 and magnetic induction switch assembly, and this inlet channel is in upright state in water heater, and the inlet of inlet channel is compared carefully with its cavity, and when water flowing not, the float 12 that contains permanent magnet just in time is positioned at the water inlet place and can't drops out.The top of float is provided with spacer pin 24, and the outer wall of inlet channel 9 is provided with magnetic induction switch 11, and inductive switch 11 is corresponding to the position between stopping means 24 and the float 12, promptly corresponding in spacer pin 24 is equivalent to the altitude range of float 12 downwards.
Shown in Fig. 1～3, operation principle operating process of the present utility model is achieved in that at first opens inlet valve, current promote float 12 and are moved upwards up to spacer pin 24 places along inlet channel 9, the magnetic force that is provided with permanent magnet 13 in the float 12 triggers magnetic induction switch 11 and produces the signal of telecommunication, pass to impulse generator, the magnetic valve 3 that pulse signal is passed on pulse igniter on the burner and triggering gas circuit is respectively opened again.At this moment, valve spool 18 does not resemble the traditional structure starting one step ahead and opens, thereby enters burner and cause " detonation ", valve spool 18 really to play the effect of the second road easing valve of combustion gas with regard to not having combustion gas.Have only when the hydraulic pressure thrust plate 16 of current by barrier film 14 promotion aqueous vapor linkages, drive the little axle 17 that is attached thereto and move unseat the valve spool 18, gas circuit is unimpeded, and combustion gas enters burner and lighted.Hydraulic pressure is big more, the corresponding increase of the aperture of valve spool, and vice versa.Water flow pressure disappears, and valve spool 18 is realized resetting by the elastic force of back-moving spring 19.Even, also have the magnetic induction switch 11 that is positioned at water inlet and signal to impulse generator one step ahead and control the air inlet closed electromagnetic valve, thereby avoid " dry combustion method " phenomenon of taking place because of cutting off the water suddenly just in case the abnormal conditions that valve spool 18 does not reset fully occur.When occurring cutting off the water, the magnetic float 12 that is positioned at inlet channel lost current holder power and because of conducting oneself with dignity downward landing, the position that disengaging and magnetic induction switch 11 are corresponding, magnetic induction switch 11 thereby be triggered and send signal to impulse generator.
If what enter when opening water intaking valve is not water, but remaining pressure air in the water route, the float 12 of water inlet can be held up and be triggered magnetic induction switch 11, thereby cause producing pulse signal and trigger the burner igniting, electromagnetic valve of gas circuit 3 is opened, but do not have enough pressure the aqueous vapor linkage is moved owing to pressure air flows away from water outlet rapidly, so gas circuit is stopped up by valve spool 18, thereby burner do not have combustion gas and enters and lighted, and " dry combustion method " just can not take place yet and damages heat exchanger.
Also be provided with a switching magnetic valve in the gas circuit of aqueous vapor interstage valve between gas outlet 2 and burner that has, but, this magnetic valve controls because remaining the signal source that is subjected to from mechanical type microswitch on traditional aqueous vapor interstage valve produces, open synchronously with the magnetic valve of control air inlet, gas circuit is unimpeded; But when cutting off the water, bad if the valve spool 18 of aqueous vapor interstage valve resets, can not trigger on the aqueous vapor interstage valve mechanical type microswitch and produce the signal controlling magnetic valve and in time close.Like this, it is logical that gas circuit remains, thereby " dry combustion method " will take place burner, and dual-coil electromagnetic valve control does not have safety effect yet.And the utility model scheme adopts reliability magnetic induction switch replacement preferably mechanical type microswitch to produce signal source, and separates with the aqueous vapor interstage valve, solves gas circuit open and close controlling problem preferably, takes place thereby effectively prevent " dry combustion method " phenomenon.
Shown in Fig. 4,5, can also process one or more semi-circular groove 26 at the inwall of inlet channel 9 along water (flow) direction, can play the effect of the part resistance of offsetting float 12, certain guide functions is arranged again.And can offer the oblique guiding gutter 25 of some parallel distributions in the porch of inlet channel, can cause that current produce rotation, prevent that float 12 is stuck because of incrusted deposit.
As shown in Figure 6, water regulating valve in the utility model can adopt the control valve with three gears, first grade hydraulic pressure starting value is 0.01～0.02Mpa, and second grade hydraulic pressure starting value is 0.02～0.03Mpa, and the hydraulic pressure starting value of third gear is 0.03～0.04Mpa.
