Abstract
The utility model relates to a suction and exhaust valve used for sewage with plenty impurities and large air content, particularly to a suction and exhaust valve used for sewage with multiple impurities and large air content, which is characterized in that vent holes are enlarged, therefore, the large amount of air in the sewage is exhausted more easily, and simultaneously the blockage is avoided; as the vent holes are under the protection of a guide rod on a floating ball and are prevented from being contacted with easily-crusted air bubbles in the sewage air, the possibility of blockage is reduced and the long-term operation is ensured; and at the same time, as the floating ball is arranged in the right middle position, the diameter of the valve body is reduced, and as the spherical floating ball is adopted, the contact area between the floating ball and the liquid level is increased, and the valve body is shortened. The suction and exhaust valve overcomes the defects of the existing suction and exhaust valve, such as blockage caused by the impurities and the small air-out volume caused by too small sizes of the air outlets.
Description
Technical field
The utility model relates to a kind of sewage air inlet and exhaust valve, specifically a kind ofly is used for that impurity is many, the air inlet and exhaust valve of large-minded sewage.
Background technique
Outlet valve is of a great variety at present, but the sewage outlet valve is less relatively.What adopt usually in existing is the sewage composite exhaust valve; The sewage outlet valve shown in accompanying drawing 1 commonly for example, valve body includes parts such as lever and ball float, and wherein oval ball float is near a side of valve body; Lever is positioned at the corresponding side of ball float, and bonnet is positioned at a side of valve gap.When the valve body water filling, ball float drops to the bottom of valve body under action of gravity, and a large amount of pressed gas are discharged rapidly from exhaust port.After air is discharged, the water in the pipe in valve body lower portion gets into valve, the ball float come-up in the valve body, up to movable masthead to the valve port place, and air inlet and exhaust valve is closed automatically and is stopped exhaust and do not sluice.The air that dissolves in the water in the pipe gets in the valve, and the water surface descends gradually in the valve, and motion bar is held and can not be descended automatically by gas.Reduce to ball float when following when the water surface in the valve body, ball float is relied on power for support, and valve port is opened and given vent to anger in a large number.The existing shortcoming of this type valve is a complex structure at present, and stressed member is more, and is bulky, and the air outlet is too small, causes impurity easy blocking air outlet.
Summary of the invention
The utility model is to the existing complex structure of existing sewage air inlet and exhaust valve; Stressed member is more; Bulky, the air outlet is too small, causes deficiencys such as impurity easy blocking air outlet; Provide a kind of and can be used for that impurity is many, the air inlet and exhaust valve of large-minded sewage, stop up and because the little defective of the too small gas output that causes in air outlet thereby overcome the existing impurity of existing sewage air inlet and exhaust valve.
The utility model solves the technological scheme that its technical problem adopted: a kind of sewage air inlet and exhaust valve comprises valve body, valve gap, ball float, hydrodynamic reciprocating sealing bar, air outlet, air outlet hole and hanger.Said valve gap is fixedly mounted on said valve body upper end, and said valve gap is provided with said air outlet; Be installed with bonnet on the said air outlet; Said bonnet is provided with air outlet hole; Lower end, said air outlet is equipped with Gask-O-Seal, and said air outlet place is equipped with hydrodynamic reciprocating sealing bar moving up and down, and said seal bar middle part is installed with; Be disposed with vent from top to bottom below the above is taken over a business at said hydrodynamic reciprocating sealing bar, gas can be discharged by said air outlet hole through said vent in the valve; Said valve gap lower end and saidly take over a business the lower end Gask-O-Seal all is installed; Said hydrodynamic reciprocating sealing bar is a hollow tubular, and middle lower end is arranged in the said guide rod, and can be up and down in said guide rod; The other end of said guide rod is installed with circular stainless steel floating ball, and said valve gap is provided with hanger, when said guide rod moves up and down because of said ball float, can said guide rod be hung on the said hanger.
The working principle of the valve that the utility model is related is: when valve body injected sewage, the hydrodynamic reciprocating sealing bar hung on the hanger under action of gravity with the guide rod that is connected with ball float, and gas is discharged rapidly through the air outlet; After sewage gets into valve body from water intake; The valve body inner float ball promotes guide rod and moves upward at the buoyancy function float downward, and then promotion hydrodynamic reciprocating sealing bar moves upward; Until taking over a business to block the air outlet, the bring into operation exhaust in stage of system so far finishes; In system's running, can produce a large amount of gas bubbles in the sewage, slowly collect in the valve body, under the effect of gas bubbles pressure; Sewage reduces gradually in the valve body, effect of buoyancy, and ball float will descend under the effect of gravity; And the hydrodynamic reciprocating sealing bar with take over a business owing under the gas pressure effect in valve body, can not descend, when ball float drops to the vent A that exposes successively on the hydrodynamic reciprocating sealing bar, B; Gas can be discharged from air outlet hole through vent A, B, and air pressure descends, and sewage continues to get into again and rises; Ball float rises and blocks the air outlet again, and scavenging action is played in circulation so repeatedly.
The beneficial effect of the valve that the utility model is related is following:
1, strengthens the size of vent, help the discharge of a large amount of gases in the sewage, can prevent simultaneously to stop up.
2, vent is among the protection of the guide rod on the ball float, can not touch the bubble that crusts easily in the sewage gas, reduces and stops up, and guarantees long-play.
3, because the ball float position is in the position, middle, reduced the diameter of whole valve body, employing be that circular ball float can increase the area of contact with liquid level, also can reduce the length of valve body.
4, whole design stressed member has only three, valve body, ball float, valve gap, other do not receive too big pressure, strengthened reliability of operation.
5, reduced the number of part, 5 of 3 other parts of seal ring reduce the die sinking number, reduce cost.
