Abstract
The invention relates to a sewage inlet/exhaust valve, specifically to an inlet/exhaust valve for sewage containing lots of impurities and gases. The exhaust valve is provided with a gas vent having an enlarged size, which is advantageous for the exhausting of a large quantity of gases in the sewage, and simultaneously capable of preventing blockage; the gas vent is under the protection of a guide rod on a floating ball without contacting with bubbles easily incrusted in the sewage gases, thereby reducing blockage and ensuring long-term operation; besides, the position of the floating ball is in the middle position, so that the diameter of the whole valve body is reduced; and a circular floating ball is employed so that the contact area thereof with the liquid level can be widened and the length of the valve body can be also reduced. The exhaust valve overcomes the defects of impurity blockage and low gas output caused by a small gas outlet of the existing sewage inlet/exhaust valve.
Description
Technical field
The present invention relates to a kind of sewage air inlet and exhaust valve, specifically a kind ofly be 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, as shown in Figure 1 sewage outlet valve 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 enters 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 enters 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 class valve is a complex structure at present, and stressed member is more, and is bulky, and the air outlet is too small, causes impurity to stop up the air outlet easily.
Summary of the invention
The present invention is directed to the existing complex structure of existing sewage air inlet and exhaust valve, stressed member is more, bulky, the air outlet is too small, cause impurity to stop up deficiencys such as air outlet easily, 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 technical solution adopted for the present invention to solve the technical problems is: 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.Described valve gap is fixedly mounted on described valve body upper end, and described valve gap is provided with described air outlet; Be installed with bonnet on the described air outlet, described bonnet is provided with air outlet hole, lower end, described air outlet is equipped with Gask-O-Seal, and place, described air outlet is equipped with hydrodynamic reciprocating sealing bar moving up and down, described seal bar middle part is installed with, be disposed with vent from top to bottom below the above is taken over a business at described hydrodynamic reciprocating sealing bar, gas can be discharged by described air outlet hole by described vent in the valve; Described valve gap lower end and describedly take over a business the lower end Gask-O-Seal all is installed; Described hydrodynamic reciprocating sealing bar is a hollow tubular, and middle lower end is arranged in the described guide rod, and can be up and down in described guide rod; The other end of described guide rod is installed with circular stainless steel floating ball, and described valve gap is provided with hanger, when described guide rod moves up and down because of described ball float, described guide rod can be hung on the described hanger.
The working principle of valve involved in the present invention is: when valve body injects sewage, the hydrodynamic reciprocating sealing bar hangs on the hanger under action of gravity with the guide rod that is connected with ball float, gas is discharged rapidly through the air outlet, after sewage enters 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, buoyancy weakens, and ball float will descend under the effect of gravity, and the hydrodynamic reciprocating sealing bar and take over a business since the gas pressure effect in valve body under, can not descend, drop to the vent A that exposes successively on the hydrodynamic reciprocating sealing bar when ball float, during B, gas can pass through vent A, B discharges from air outlet hole, and air pressure descends, sewage continues to enter 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 valve involved in the present invention is as follows:
1, strengthen the size of vent, help the discharge of a large amount of gases in the sewage, simultaneously can pre-anti-plugging.
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 be not subjected to 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.
