The utility model discloses profitable effect is: can prevent the destruction that velocity of water flow led to the fact the air bleeding valve at the excessive speed, prevent the water hammer, can solve the problem that the water hammer appears in present air bleeding valve easily, make the air bleeding valve not fragile, excellent in use effect does benefit to the popularization.
Description
Technical field
The utility model relates to valve technology field, particularly relates to a kind of water hammer-resistant outlet valve.
Background technique
At present, easily there is water hammer in outlet valve common on the market, when water hammer refers to that valve opens and closes suddenly or feed water pump starts stopping, pressure reduction is there is in pipeline, owing to having certain air in current, now, just pressure effect is produced to the air in current, air push water movement, the too fast formation water hammer of flow rate of water flow, damages effect to valve, therefore, outlet valve common on the market easily damages under water hammering, and practical application effect is poor.
Model utility content
The utility model will solve above-mentioned prior art Problems existing, provides a kind of water hammer-resistant outlet valve, solves the problem that water hammer easily appears in current outlet valve, meet the user demand of outlet valve.
The utility model solves the technological scheme that its technical problem adopts: this water hammer-resistant outlet valve, comprise valve body, the bottom of valve body has import, the top of valve body is provided with valve gap, valve gap has relief opening, the below of relief opening is provided with ball float, ball float is arranged in valve body, the bottom of ball float is connected with guide rod, ball seat is provided with in valve body, guide rod is connected on ball seat, ball seat is connected with kickboard, kickboard is connected on the inwall of valve body, kickboard has one group of exhaust port, the both sides of ball seat are all connected with cushion plate, the curved state of cushion plate is arranged, cushion plate is positioned at the top of kickboard.Such setting, during use, when gas enters into valve body by kickboard from current, due to kickboard having exhaust port, gas can only enter in valve body from exhaust port and be vented, which reduce the leaving area of gas, reduce the exhaust velocity of gas, thus the pressure reduction between making inside and outside valve body reduces, like this when outlet valve starts suddenly or closes, because valve body inside and outside differential pressure is little, therefore, the pressure produced in valve body is little, under the pressure effect that air in current is produced, the impact caused the flow velocity of current is little, thus prevent water hammer, simultaneously, ball seat arranges cushion plate, because the curved state of cushion plate is arranged, such water impact decreases flow velocity to the streaming buffer effect by cushion plate during valve, prevent the destruction that water impact causes valve body, be combined with each other thus inhibit the flow velocity of current, prevent water hammer, prevent the damage of outlet valve,
The top of valve gap is provided with enclosing cover, and enclosing cover is arranged on valve body.Such setting, enclosing cover plays a protective role.
Enclosing cover is arranged on valve body by bolt.Such setting, adopts bolt good fixing effect.
The effect that the utility model is useful is: water hammer-resistant outlet valve of the present utility model, rational in infrastructure, easy to use, the set-up mode of employing kickboard can reduce the pressure reduction inside and outside valve body, reduce the pressure effect to air in current, slow down the flow velocity of current, adopt the set-up mode of cushion plate can slow down the flow velocity of current, be combined with each other thus reach the object slowing down flow rate of water flow, prevent the too fast destruction that outlet valve is caused of flow rate of water flow, prevent water hammer, the problem that water hammer easily appears in current outlet valve can be solved, make outlet valve not fragile, using effect is good, be beneficial to popularization.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model embodiment.
Description of reference numerals: valve body 1, import 2, valve gap 3, relief opening 4, ball float 5, guide rod 6, ball seat 7, kickboard 8, exhaust port 9, cushion plate 10, enclosing cover 11, bolt 12.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: this water hammer-resistant outlet valve in the present embodiment, comprise valve body 1, the bottom of valve body 1 has import 2, the top of valve body 1 is provided with valve gap 3, valve gap 3 has relief opening 4, the below of relief opening 4 is provided with ball float 5, ball float 5 is arranged in valve body 1, the bottom of ball float 5 is connected with guide rod 6, ball seat 7 is provided with in valve body 1, guide rod 6 is connected on ball seat 7, ball seat 7 is connected with kickboard 8, kickboard 8 is connected on the inwall of valve body 1, kickboard 8 has one group of exhaust port 9, the both sides of ball seat 7 are all connected with cushion plate 10, the curved state of cushion plate 10 is arranged, cushion plate 10 is positioned at the top of kickboard 8.
The top of valve gap 3 is provided with enclosing cover 11, and enclosing cover 11 is arranged on valve body 1.
Enclosing cover 11 is arranged on valve body 1 by bolt 12.
Kickboard 8 is fitted with the inwall of valve body 1 and is contacted, and achieves seamless link.
During use, when gas enters into valve body 1 by kickboard 8 from current, due to kickboard 8 having exhaust port 9, gas can only enter in valve body 1 from exhaust port 9 and be vented, which reduce the leaving area of gas, reduce the exhaust velocity of gas, thus the pressure reduction between making inside and outside valve body 1 reduces, like this when outlet valve starts suddenly or closes, because valve body 1 inside and outside differential pressure is little, therefore, the pressure produced in valve body 1 is little, under the pressure effect that air in current is produced, the impact caused the flow velocity of current is little, thus prevent water hammer, current impact on cushion plate 10 through after kickboard 8, because the curved state of cushion plate 10 is arranged, thus slow down the flow velocity of current, reach the effect slowing down flow rate of water flow.
The feature of the utility model embodiment is: the set-up mode of employing kickboard 8 can reduce the pressure reduction inside and outside valve body 1, reduce the pressure effect to air in current, slow down the flow velocity of current, adopt the set-up mode of cushion plate 10 can slow down the flow velocity of current, be combined with each other thus reach the object slowing down flow rate of water flow, prevent the too fast destruction that outlet valve is caused of flow rate of water flow, prevent water hammer, the problem that water hammer easily appears in current outlet valve can be solved, make outlet valve not fragile, using effect is good, is beneficial to popularization.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
