Extension side is fixed on the combustion gas gas circuit inwall of valve body 1, and the end of valve element post 302 is provided with the valve 303 for blocking combustion gas gas circuit, valve body
1 combustion gas gas circuit inwall is provided with special-shaped gas and shaken ring mounting groove 4, and special-shaped gas shakes in ring mounting groove 4 and shaken ring 5, abnormity provided with special-shaped gas
The gas ring 5 that shakes by the first V-type positioning section 502, the second V-type positioning section 503, the 3rd V-type positioning section 504 and is fixedly connected with the structure of section 505
Into the first V-type positioning section 502, the second V-type positioning section 503 are provided with and are fixedly connected with section between any two with the 3rd V-type positioning section 504
505, it is fixedly connected with section 505 and is fixed on special-shaped gas and shakes in ring mounting groove 4, the first V-type positioning section 502, the second V-type positioning section 503
It is fixed in the 3rd V-type positioning section 504 on valve element post 302.
As shown in Figures 2 and 3, in the present embodiment, the section 505 that is fixedly connected shakes special-shaped gas ring provided with resigning mouth 501
5, which are installed to special-shaped gas, shakes in ring mounting groove 4, i.e., first compress special-shaped gas and shake ring 5, the gap shrinks of resigning mouth 501, and special-shaped gas shakes ring 5
Reduced overall, is then placed in special-shaped gas and shakes in ring mounting groove 4, unclamps special-shaped gas and shakes ring 5, and the special-shaped gas ring 5 that shakes is fixed in special-shaped gas
Shake ring mounting groove 4, the gap of resigning mouth 501 be 1mm~5mm, special-shaped gas shake ring 5 fix after resigning mouth 501 still have gap, make
Special-shaped gas shakes the surplus of the elastic deformation of ring 5, special-shaped gas is shaken the Quick-return original state of ring 5.
As shown in figure 4, in the present embodiment, the end of resigning mouth 501 is provided with clamping part 506, special-shaped gas is shaken into 5 sets of ring admittedly
When on to valve element post 302, the special-shaped gas ring 5 that shakes is installed and there is the problem of installation operation is inconvenient, clamping part 506 is clamped by fixture
With regard to the problem of installation operation is inconvenient can be solved.
As shown in Figure 2 to 4, in the present embodiment, the first V-type positioning section 502, the and of the second V-type positioning section 503
The top of the 3rd V-type positioning section 504 is circular arc, and the structure of section 505 that is fixedly connected is annular, first V-type
Positioning section 502, the segment angle of the second V-type positioning section 503 and the 3rd V-type positioning section 504 between any two are 120 °, the
One V-type positioning section 502, the second V-type positioning section 503 and the 3rd V-type positioning section 504 constitute bikini location structure, pass through the first V
Type positioning section 502, the second V-type positioning section 503 and the 3rd V-type positioning section 504 can radially wobble gap with respect to restriction valve element 3
So that valve element 3 is not easy dither during preceding pressure P1 change, is conducive to eliminating gas and shakes and utter long and high-pitched sounds, the first V-type positioning section 502, the
Two V-type positioning sections 503 and the top of the 3rd V-type positioning section 504 are circular arc, its contact with valve element 3 is contacted for point, make abnormity
Gas shake ring 5 and valve element 3 axial movement frictional force and be not significantly changed, from without influenceing the sensitivity and voltage stabilizing that valve element 3 moves
The validity of function.
As shown in Figure 5 and Figure 6, in the present embodiment, the first V-type positioning section 502, the and of the second V-type positioning section 503
The top of the 3rd V-type positioning section 504 is 0.05mm~0.15mm with the gap of valve element post 302, defines the footpath of valve element 3
Dither is not likely to produce to valve element 3 when swinging pressure P1 changes before gap causes, and valve element post 302 is in different opening, no
Can because special-shaped gas shake ring 5 three-point fix effect increase axial friction, as shown in figure 5, not being mounted with that special-shaped gas shakes ring 5
Gas ratio valve, in electric current 136mA, 160mA, preceding pressure P1 is in 3000Pa, and gas ratio valve starts gas and shake to cause to press just after P2
Start bounce upwards, parameter of curve drift；As shown in fig. 6, being mounted with that special-shaped gas shakes the gas ratio valve of ring 5, in electric current
136mA, 160mA, preceding pressure P1 press no bounce in 3000Pa after gas ratio valve P2, parameter of curve is effectively solved without drift phenomenon
The gas of existing structure of having determined shakes and uttered long and high-pitched sounds phenomenon.
As shown in Fig. 2 in the present embodiment, the special-shaped gas ring 5 that shakes shakes ring to the spacing of valve 303 and the special-shaped gas
5 to the gap ratio of epithelium 301 be 1：1~10, the special-shaped gas ring 5 that shakes changes the location structure of valve element 3, changes consolidating for valve element 3
Surely there is frequency, breach the existing limitation without friction positioning, the progress bikini gas of valve element post 302 that can be shaken and utter long and high-pitched sounds to gas shakes
With positioning of uttering long and high-pitched sounds, the radial and axial positioning spacing of valve element 3 is defined, makes valve element 3 when preceding pressure P1 is in 3000Pa, parameter of curve
Without drift phenomenon.
In use, gas shake and utter long and high-pitched sounds be from external vibration frequency and intrinsic frequency reach consistent when the resonance that produces show
As magnetic valve magnetic thrust line bag 2 drives the aperture of valve element 3 bigger, gas situation of shaking and utter long and high-pitched sounds is more serious, or even influence hot water
The normal of device is used, combustion gas from combustion gas gas circuit enter gas ratio valve in when, the valve element post 302 of valve element 3, which is produced, to be radially wobbled, and is produced
Raw dither, occurs gas and shakes and utter long and high-pitched sounds phenomenon, and special-shaped gas is provided with the junction of valve element 3 and is shaken ring mounting groove 4, and is provided with it
Special-shaped gas shakes ring 5, and special-shaped gas shakes the first V-type positioning section 502, the second V-type positioning section 503 and the 3rd V-type positioning section 504 of ring 5
Shake and contacted with positioning circular arc point of uttering long and high-pitched sounds for bikini gas with valve element post 302, change the intrinsic frequency of valve element post 302, at 3 points
Formula gas shakes and uttered long and high-pitched sounds the relative valve element 3 when radially wobbling pressure P1 changes before gap causes for defining valve element 2 of positioning in operating pressure
In the range of do not produce dither, special-shaped gas shakes sensitivity that ring 5 ensures that valve element 3 moves and the validity of voltage stabilizing function, simultaneously
Efficiently solve the problem of gas shakes and uttered long and high-pitched sounds.
In addition to the implementation, the present invention can also have other embodiment.All use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within protection scope of the present invention.
