Abstract
The utility model discloses an efficient automatic exhaust valve which comprises a valve body. A floater is arranged in a valve cavity of the valve body, an air inlet communicated with the valve cavity is arranged at the bottom of the valve body, the valve cavity, the floater and the air inlet are located on the same axis, a circular groove between the valve cavity and the floater serves as an air rising channel, the diameter of the air inlet is larger than or equal to 0.8 time of that of the floater, and a plurality of axial ventilation grooves distributed circumferentially and evenly are arranged at the lower section of the wall of the valve cavity. Through enlargement of the air inlet and increasing of the ventilation grooves, the efficient automatic exhaust valve can improve air displacement substantially. When a liquid medium in a pipe is water and pipe pressure is larger than 0.25MPa, exhaust capability of the efficient automatic exhaust valve exceeds more than 100 times of that of a traditional exhaust valve.
Description
(1) technical field:
The utility model relates to valve, particularly a kind of can discharge conduit the efficient automatic control pressure vent of unnecessary gas in (be the pipeline of fed sheet of a media with liquid).
(2) background technique:
It is in the pipeline of fed sheet of a media that automatic control pressure vent is mainly used in liquid, and purpose is gas unnecessary in the discharge conduit, prevents that pipeline pressure from changing, thereby elements such as ducted pump, valve are shielded.
The venting capacity of in fact this automatic control pressure vent is very poor, finds through overtesting, and there is 1% of gas in the gas gross that can discharge not as good as in the pipeline, does not play scavenging action basically.The main cause that does not play scavenging action is: do not have liquid in pipeline, when pump has just been started working, liquid can be full of the gas storage chamber of outlet valve quickly, automatic control pressure vent can only be drained the air on gas tank top, and ducted a large amount of gas is in pipeline during with flow of fluid, when should gas arriving gas tank, because gas compares liquid light, gas can rise in the gas storage chamber of automatic control pressure vent automatically, and outside the expulsion valve, in fact this process does not realize, because be full of liquid in the gas storage chamber this moment, gas in the pipeline wants to enter gas storage chamber by inlet hole, just must drain the liquid in the gas storage chamber earlier, but because the inlet hole diameter of old outlet valve generally smaller (the inlet hole diameter d is generally less than 0.5D, and D is the float diameter), liquid can't be drained from inlet hole, therefore gas then can't rise in the gas storage chamber, and is can't expulsion valve external.
And ducted gas is more much more than the gas of gas storage chamber, and along with the work of pump, constantly sucks gas from the external world, and ducted gas is more and more, has a strong impact on the performance of each element of pipeline.
(3) model utility content:
The utility model provides a kind of efficient automatic control pressure vent, and its main purpose is to make that gas rises in the gas storage chamber of outlet valve in the pipeline, drains the liquid in the outlet valve gas storage chamber simultaneously, makes the degassing function of outlet valve normally bring into play.
Can realize the efficient automatic control pressure vent of above-mentioned purpose, comprise valve body, be provided with float in the valve pocket of described valve body, the valve body bottom offers suction port and is communicated with valve pocket, described valve pocket, float, suction port are on the same axis, annular groove between valve pocket and the float is the passage that gas rises, difference is: for enlargement gas rising passway and drainage channel, the diameter of described suction port increases as compared with the past to some extent, be specially the float diameter (if the float diameter of suction port diameter＜0.8 times, venting capacity will variation) of described suction port diameter 〉=0.8 times.
Be further enlargement gas rising passway and drainage channel, the hypomere of described valve cavity wall is offered many uniform axial vent slots.
The form of described vent slot has:
1, the direct pass-out valve body of described vent slot bottom.
2, for the benefit of gas is concentrated, and described valve body bottom sets out coaxial counterbore, and described counterbore and suction port form up-small and down-big step hole, and described vent slot is to counterbore.
The radial dimension of described counter bore hole diameters 〉=vent slot, effect is preferable.
The radial dimension of preferred described counter bore hole diameters＞vent slot.
In the conventional design, the length of the described vent slot≤1/2 valve pocket degree of depth.
Advantage of the present utility model:
The efficient automatic control pressure vent of the utility model can increase substantially air displacement by strengthening suction port and increasing vent slot.When ducted liquid medium is water and pipeline pressure during greater than 0.25MPa, venting capacity of the present utility model surpasses traditional outlet valve more than 100 times.

(5) embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is described further.
The efficient automatic control pressure vent of the utility model comprises valve body 2 and valve gap 7, it is suitable for reading that described valve gap 7 is combined on valve body 2, horizontal exhaust gear 6 is set in the valve gap 7, described exhaust gear 6 hangs float 1 in the valve pocket of valve body 2 by hook 8, annular groove between valve pocket and the float 1 is the passage that gas rises, the Lower Half of described valve body 2 increases than first half diameter, and valve body 2 bottoms are connected on the screw socket of pipeline by outside thread; The up-small and down-big step hole that is formed by suction port 3 and counterbore 5 is offered in the bottom of described valve body 2, described suction port 3 is communicated with valve pocket, offer four or six axial vent slots 4 of circumference uniform distribution on the valve body 2 Lower Half valve cavity walls, described valve pocket, float 1, suction port 3 and counterbore 5 are on the same axis, as shown in Figure 1.
Shown in Fig. 2 (a), Fig. 2 (b), the float 1 diameter D of described suction port 3 diameter d 〉=0.8 times does not offer vent slot 4 on the valve cavity wall.
Shown in Fig. 3 (a), Fig. 3 (b), the float 1 diameter D of described suction port 3 diameter d 〉=0.8 times offers four or six axial vent slots 4 of pass-out valve body 2 bottoms on the valve cavity wall of valve body 2 Lower Halves.
Shown in Fig. 4 (a), Fig. 4 (b), the float 1 diameter D of described suction port 3 diameter d 〉=0.8 times, counterbore 5 is offered in valve body 2 bottoms, described suction port 3 forms up-small and down-big step hole with counterbore 5, offer four or six axial vent slots 4 passing to counterbore 5 on the valve cavity wall of valve body 2 Lower Halves, counterbore 5 diameter d 1 are greater than the radial dimension F of vent slot 4.
As Fig. 5 (a), Fig. 5 (b), the float 1 diameter D of described suction port 3 diameter d 〉=0.8 times, counterbore 5 is offered in valve body 2 bottoms, described suction port 3 forms up-small and down-big step hole with counterbore 5, offer four or six axial vent slots 4 passing to counterbore 5 on the valve cavity wall of valve body 2 Lower Halves, counterbore 5 diameter d 1 equal the radial dimension F of vent slot 4.
The working procedure of the efficient automatic control pressure vent of the utility model:
As shown in Figure 1, when in the gas storage chamber 9 between float 1 and the valve pocket bottom during no liquid, float 1 descends, by linking up with the 8 exhaust passage exhausts of opening exhaust gear 6.After gas had been arranged, when having liquid to pass through in the pipeline, liquid entered gas storage chamber 9, float 1 come-up, and hook 8 controls that lose exhaust gear 6, the exhaust passage is closed, and liquid that can not effluxes in the valve; When having gas in the pipeline, gas reaches the valve pocket top smoothly by suction port 3 and vent slot 4, and the liquid at valve pocket top is back to the valve pocket bottom smoothly by suction port 3 and vent slot 4, when the air accumulation at valve pocket top is abundant, gas pressure promotes float 1 and descends, by linking up with the 8 exhaust passage exhausts of opening exhaust gear 6.
