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 of air inlet and exhaust valve of, large-minded sewage many for impurity.
Background technique
Outlet valve is of a great variety at present, but sewage exhaust valve is relatively less.What in existing, conventionally adopt is sewage composite exhaust valve, sewage exhaust valve as shown in Figure 1 commonly for example, valve body includes the 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 valve body water filling, ball float, under Action of Gravity Field, drops to the bottom of valve body, and a large amount of pressed gas are discharged rapidly from exhaust port.After Bas Discharged, the water in pipe in valve body lower portion enters valve, ball float in valve body floating, until by movable masthead to valve port place, and air inlet and exhaust valve is automatically closed and is stopped exhaust and do not sluice.The air dissolving in water in pipe enters in valve, and in valve, the water surface declines gradually, and motion bar is held and can not automatically be declined by gas.In valve body, the water surface is down to ball float when following, and ball float is borrowed gravity fall, and valve port is opened and given vent to anger in a large number.The existing shortcoming of this class valve is complex structure at present, and stressed member is more, bulky, and air outlet is too small, causes impurity easily to stop up air outlet.
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, air outlet is too small, cause impurity easily to stop up the deficiencys such as air outlet, provide a kind of can be many for impurity, the air inlet and exhaust valve of large-minded sewage, thereby overcome that the existing impurity of existing sewage air inlet and exhaust valve stops up and due to the little defect of too small the caused gas output in air outlet.
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, is provided with described air outlet on described valve gap; On described air outlet, be installed with bonnet, on described bonnet, be provided with air outlet hole, lower end, described air outlet is provided with Gask-O-Seal, and place, described air outlet is provided with hydrodynamic reciprocating sealing bar moving up and down, described seal bar middle part is installed with, below the above is taken over a business at described hydrodynamic reciprocating sealing bar, be disposed with from top to bottom vent, in valve, gas can be discharged by described air outlet hole by described vent; Described valve gap lower end and described in take over a business lower end Gask-O-Seal be all installed; Described hydrodynamic reciprocating sealing bar is hollow tubular, and middle lower end is arranged in 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, on 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 described hanger.
The working principle of valve involved in the present invention is: when valve body injects sewage, hydrodynamic reciprocating sealing bar hangs on hanger under Action of Gravity Field with the guide rod that is connected with ball float, gas is discharged rapidly through air outlet, when sewage is from water intake enters valve body, valve body inner float ball, at the effect float downward of buoyancy, promotes guide rod and moves upward, and then promotion hydrodynamic reciprocating sealing bar moves upward, until take over a business to block air outlet, the bring into operation exhaust in stage of system so far finishes, in system running, in sewage, can produce a large amount of gas bubbles, slowly collect in valve body, under gas bubbles pressure-acting, in valve body, sewage reduces gradually, buoyancy weakens, ball float will decline under the effect of gravity, and hydrodynamic reciprocating sealing bar and taking over a business due under the gas pressure effect in valve body, can not decline, when ball float drops to the vent A exposing successively on hydrodynamic reciprocating sealing bar, during B, gas can pass through vent A, B discharges from air outlet hole, air pressure declines, sewage continues to enter again and rises, ball float rises and blocks air outlet again, iterative cycles like this, play scavenging action.
The beneficial effect of valve involved in the present invention is as follows:
1, strengthen the size of vent, be conducive to the discharge of a large amount of gases in sewage, simultaneously can pre-anti-plugging.
2, among the protection of the guide rod of vent on ball float, can not touch the bubble easily crusting in sewage gas, reduce and stop up, guarantee long-play.
3, because ball float position is in 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 only has three, valve body, ball float, valve gap, other be not subject to too large pressure, strengthened reliability of operation.
5, reduced the number of part, 5 of 3 other parts of seal ring, reduce die sinking number, reduce costs.
