Detailed description of the invention
As shown in Figures 1 to 7, of the present utility model including limited support 1 and sealing member 2, this sealing member 2 can be along limit
Position support 1 length direction is movably arranged in this limited support 1, and the length direction both ends of the surface of limited support 1 all have supply
The through hole 10 that body or liquid pass through, the size being smaller in size than sealing member 2 of this through hole 10, super at gas or liquid of sealing member 2
Pressure blocks through hole 10 when moving the wherein one end to limited support 1, and therefore this valve protection device had both played overcurrent-overvoltage
Protective effect, play again the protective effect of anti-backflow, practical, moreover it is possible to ensure the normal circulation of gas-liquid.
As it is shown on figure 3, the limited support 1 of this embodiment includes base 11, flap 12 and three gag lever posts 13, Qi Zhongsuo
Some gag lever posts 13 are spaced ringwise, and this base 11 is connected with one end of all gag lever posts 13, and flap 12 is then limited with institute
The other end of position bar 13 connects, in this sealing member 2 is arranged on the annular that all gag lever posts 13 are surrounded and can be along gag lever post 13
Length direction moves, and this through hole 10 is opened in the middle of base 11 and flap 12.Concrete, as in figure 2 it is shown, this embodiment is spacing
Bar 13 and base 11 are one-body molded designs, and such design had both reduced operation, reduce difficulty of processing, and ensure between the two
Fastness, and be machined with connection post 32 in the other end of gag lever post 13, uniform on the flap 12 of this embodiment have three
Connecting hole 31, is inserted into this connecting hole 31 by connection post 32, may then pass through spot welding or other modes so that connect post 32 with
Connecting hole 31 is fixed, thus realizes gag lever post 13 and be connected with flap 12；Before flap 12 is connected with gag lever post 13, need
First sealing member 2 being put in the space that three gag lever posts 13 surround, the sealing member 2 of this embodiment is for sealing the centre of sphere 2, this sealing
The weight of the centre of sphere 2 can select according to air-flow or flow stream pressure size, to ensure under the safety range pressure of regulation, and ball sealer
The heart 2 can be maintained at the medium position of gag lever post 13, and this sealing centre of sphere 2 can block the through hole 10 of base 11 when there is superpressure.
Meanwhile, in order to ensure that this sealing centre of sphere 2 can fit tightly to reach plugging action with through hole 10, this embodiment through hole 10 towards
The bore edges at this sealing member 2 place is provided with chamfering 101, therefore when sealing the centre of sphere 2 near through hole 10, its sphere energy and fillet surface
Fit tightly.
As shown in Figure 4, the limited support 1 of this embodiment is provided with spring 4 at least one through hole 10, consolidating of this spring 4
Fixed end is positioned at through hole 10, and the movable end of spring 4 towards the direction at sealing member 2 place.General if arranging single bullet
If spring 4, this spring 4 is installed in the direction of anti-backflow protection, and i.e. when occurring flowing backwards, this sealing member 2 can be at the gas flow backwards
Or under the effect of liquid, block a through hole 10 of limit bracket 1, and spring 4 is just arranged in this through hole 10, owing to this is real
Execute the valve protection device of example and be mounted in the outlet side of valve, and one end of flap 12 is inwardly, if so only arranging one
If individual spring 4, this spring 4 is just arranged on this flap 12, specifically offers a circle groove 6 in through hole 10, and spring 4
Fixing end be then connected on " C " type ring 5, be fitted in groove 6 by this " C " type ring 5, as it is shown in figure 5, thus realize
Spring 4 is fixed on limited support 1, therefore when there is refluence phenomenon, seals the centre of sphere 2 and will be pressed towards the through hole at flap 12
10, block through hole 10, it is achieved anti-backflow, spring 4 is squeezed and compresses simultaneously；After refluence phenomenon terminates, this sealing centre of sphere 2
Will under the effect of this spring 4 self-return, it is to avoid seal the centre of sphere 2 and through hole 10 wall adhesion and cannot self-return.
As shown in Figure 6, this embodiment is to be both provided with spring 4 on the both sides of limited support 1, i.e. at the through hole 10 of base 11
With in the through hole 10 of flap 12, be mounted on spring 4, the movable end of same the two spring 4 is all directed towards sealing member 2.?
In this embodiment, it is the effect realizing anti-backflow during the through hole 10 on closure flap 12 equally, and blocks the through hole on base 11
The effect of anti-overflow overvoltage is realized when 10.
As it is shown in fig. 7, be that the valve protection device of this utility model is installed to a valve for water heater 7 shown in this figure
In, this valve protection device is mounted in the valve 7 inside near gas outlet, and this embodiment is to be provided with on the outer wall of base 11
External screw thread 14, and it is correspondingly provided with female thread at the outlet port inwall of valve 7, spun by screw thread and realize valve protection dress
Put and be arranged in valve 7, and the inner of this valve protection device, the i.e. outer face of flap 12 can be with one of valve 7 inner chamber
Step surface docks mutually, but in order to ensure that air-tightness is more preferable, before loading valve protection device, can pad at the outer face of flap 12
A upper cushion film 8.The limited support 1 of this embodiment is provided with two springs 4, the spring 4 being wherein positioned on base 11 than
The spring being positioned on flap wants thin, and main cause is that the protection device of this embodiment is mounted on valve for water heater 7,
When this valve 7 is with the wrong location be installed on tap time, the situation just having refluence occurs, and the pressure ratio of water is relatively big, institute for
The spring 4 of anti-backflow can obtain thicker with respective design, as long as its elastic force is not more than the pressure of water；This valve 7 is to use
In supply, so occurring that the situation of overcurrent-overvoltage i.e. gas flow are excessive and cause, but the pressure of gas is not after all
Can be too big, institute is accomplished by thinner for the spring 4 of anti-overflow overvoltage, it is ensured that overcurrent-overvoltage seasonal epidemic pathogens physical ability is sealing the centre of sphere 2
The through hole 10 on base 11 is pushed down on top up.
Although this utility model is to be described with reference to specific embodiments, but this description is not meant to this utility model
It is construed as limiting.With reference to description of the present utility model, other changes of the disclosed embodiments, for those skilled in the art it is all
It is anticipated that, this change should belong in appended claims limited range.
