Abstract
The utility model discloses a device for controlling air exhaust flow of an air exhaust valve. The device comprises a board body, wherein the board body is annular; at least four arc ventilation holes are symmetrically and uniformly formed in the board surface of the annular board body in a central symmetry manner at intervals; the board body is horizontally arranged above a floating ball in the valve body; and the aperture of a central through hole in the board body is smaller than the outer diameter of the floating ball. The device can automatically exhaust or suck gas in a tank and effectively stop water flow, so that multiple potential safety hazards caused by manual operation are eliminated, and the working condition is improved.
Description
Technical field
The utility model relates to a kind of device of outlet valve control extraction flow.
Background technique
Existing outlet valve automatic exhaust device, ball float will be blown afloat the obstruction relief opening when exhaust pressure reduction is bigger, stifled phenomenon occurs blowing and (blows gas shutoff and press 0.1 ~ 0.4MPa).Blowing the stifled jar interior gas that causes can't normally drain, and then influences the filtering traffic of filtering tank, does not therefore reach normal filtration yield; Frequent impact during exhaust also causes many pits on the ball float surface, makes ball float automatic vent jam pot cover not live water and leaks, and needs often to change the ball float in the valve, and frequency of maintenance is high.
Summary of the invention
The purpose of the utility model is to provide a kind of device of outlet valve control extraction flow, its can breathe out automatically or suction tank in gas and effectively block current and pass through, eliminate manually operated many potential safety hazards, improve working conditions.
The purpose of the utility model is to realize like this; A kind of device of outlet valve control extraction flow; Comprise plate body, this plate body is ring, on the plate face of ring plate body, is centrosymmetric to be uniformly distributed with at least four arc air holes are being set at interval; This plate body level is installed in the ball float top in the valve body, and the central through bore aperture of plate body is less than the external diameter of ball float.
When the utility model used, when tank body began water filling, the inlet and outlet ball float was in fully open position, carried out exhaust; When air has been arranged, in the valve during water-filling, the intake and exhaust ball float is floated and is closed relief opening, stops exhaust; When producing negative pressure in drawdown in the jar or the chance jar, then the intake and exhaust ball float can fall automatically, sucks air, avoids negative pressure to form.The utility model is simple in structure, can breathe out automatically or suction tank in gas and effectively block current and pass through, eliminated manually operated many potential safety hazards, improved working condition.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure schematic representation of the installation of the utility model;
Fig. 2 is the plan structure schematic representation of the utility model.
Embodiment
A kind of device of outlet valve control extraction flow like Fig. 1, shown in Figure 2, comprises plate body 2, and this plate body 2 is ring, on the plate face of ring plate body 2, is centrosymmetric to be uniformly distributed with at least four arc air holes 6 are being set at interval.These plate body 2 levels are installed in ball float 3 tops in the valve body 1, and ball float 3 bottom center are installed with the guide rod 5 that is set with damping spring 4.The central through bore aperture of plate body 2 is less than the external diameter of ball float 3.The utility model can breathe out automatically or suction tank in gas and effectively block current and pass through, eliminated manually operated many potential safety hazards, improved working condition.
