Abstract
The utility model discloses a kind of water hammer-resistant air valve, it comprises: valve seat, valve gap, outlet valve group, current limliting assembly, ball float, it is characterized in that, and described valve gap top is provided with retaining ring, in valve gap, be provided with a current limliting assembly that can fluctuate, on this current limliting assembly, axially have exhaust port.The positive effect of the utility model is: can realize smooth exhaust, can effectively protect pipeline.
Description
Technical field
The utility model belongs to valve field, is specifically related to a kind of water hammer-resistant air valve.
Background technique
In existing fluid circuit, conventionally can use water hammer-resistant air valve.At present the water hammer-resistant air valve in industry is owing to being subject to structural limitations, and exhaust velocity is fast, in the pipeline causing pressure surge larger, be unfavorable for pipeline smooth running, even can cause section of tubing explosion.
Summary of the invention
The purpose of this utility model is to provide a kind of exhaust stable, pipeline is had to the water hammer-resistant air valve of fine protective action, can guarantee that pipeline normally moves.
In order to realize the utility model, technical solution adopted in the utility model is as follows:
A kind of water hammer-resistant air valve, it comprises: valve seat, valve gap, outlet valve group, current limliting assembly, ball float, it is characterized in that, described valve gap top is provided with retaining ring, is provided with a current limliting assembly that can fluctuate in valve gap, on this current limliting assembly, axially has exhaust port.
Above-mentioned water hammer-resistant air valve, the large I of exhaust port of axially offering on described stream assembly is set according to valve size.
The utility model water hammer-resistant air valve is performed such exhaust, guarantees pipeline smooth running:
In the time starting water filling in pipeline, the air in pipeline enters water hammer-resistant air valve, carries out a large amount of exhausts by valve gap mouth and outlet valve group, and simultaneously mineralization pressure is poor in valve body and between barometric pressure;
Between valve body and barometric pressure, pressure reduction raises gradually, while reaching predetermined value, and the action of current limliting assembly, current limliting assembly rises, and outlet valve group part is closed, restriction exhaust velocity;
After outlet valve group part is closed, ducted air is to discharge from the exhaust port of current limliting assembly compared with low discharge, until ducted air drains;
After ducted air drains, water enters valve body, by ball float holder to valve base sealing place, the relief opening of closed valve seat and valve gap, simultaneously current limliting assembly starts to fall after rise, until its normal enable possition.
As above-mentioned exhaust process, the utility model can be realized smooth exhaust, can not cause pressure wide fluctuations in pipeline, can effectively protect pipeline.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure, valve seat 1, valve gap 2, outlet valve group 3, current limliting assembly 4, ball float 5, valve base sealing 6, retaining ring 7.
Embodiment
Embodiment 1:
As shown in the figure, a kind of water hammer-resistant air valve, it comprises: valve seat 1, valve gap 2, outlet valve group 3, current limliting assembly 4, ball float 5, valve gap 2 tops are wherein provided with retaining ring 7, valve gap 2 inside are provided with a current limliting assembly 4 that can fluctuate, and on this current limliting assembly 4, axially have exhaust port 8.
As shown in the figure, a kind of water hammer-resistant air valve, for prevent current limliting assembly 4 floated position, be also provided with retaining ring 7 on valve gap top.
As shown in the figure, above-mentioned water hammer-resistant air valve, axially has the large I of exhaust port 8 and sets according to valve size on described current limliting assembly 4.
As shown in the figure, this practical water hammer-resistant air valve is performed such exhaust, guarantees pipeline smooth running:
In the time starting water filling in pipeline, the air in pipeline enters water hammer-resistant air valve, carries out a large amount of exhausts by 2 mouthfuls of valve gaps and outlet valve group 3, and mineralization pressure is poor in valve body and between barometric pressure simultaneously;
Between valve body and barometric pressure, pressure reduction raises gradually, and while reaching predetermined value, current limliting assembly 4 moves, and current limliting assembly 4 rises, and outlet valve group 3 parts are closed restriction exhaust velocity;
After outlet valve group 3 parts are closed, ducted air is to discharge from the exhaust port 8 of current limliting assembly 4 compared with low discharge, until ducted air drains;
After ducted air drains, water enters valve body, ball float 5 is held in the palm to valve base sealing 6 places, and the relief opening of closed valve seat 1 and valve gap 2, current limliting assembly 4 starts to fall after rise simultaneously, until its normal enable possition.
The positive effect of the utility model is: can realize smooth exhaust, can effectively protect pipeline.
