Abstract
The invention discloses a double-hole exhaust valve which is characterized in that floating ball brackets are arranged on two internal sides of a valve cavity respectively, floating balls are mounted on slide ways of the floating ball brackets respectively, a valve cover is arranged on a valve body, exhaust holes corresponding to the floating balls are formed in two sides of the valve cover respectively, a top cover is mounted on the valve cover through bolts and nuts, valve cover gaskets and spacers are respectively arranged between the valve cover and the valve body, a valve rod is screwed on the valve cover in a threaded manner, a sealing ring is sleeved on the valve rod inside the valve cover, a pressing sleeve is sleeved on the valve rod, one end of the pressing sleeve contacts with the sealing ring, the other end of the pressing sleeve is tightly pressed by a pressing plate fixed onto the valve cover, a valve plate is connected with the valve rod through a bolt, and a valve plate gasket is arranged at the bottom of the valve plate. By the design of double exhaust valves, exhaust efficiency is improved, the valve cover gaskets are arranged at the exhaust valves, tightness of the cavity is enhanced, and outflow of liquid in a pipeline during exhaust is avoided.
Description
Technical field
The present invention relates to a kind of valve, is a kind of outlet valve of diplopore specifically.
Background technique
In factory, conventional pipeline carrys out delivery industry liquid substance, in the industrial type fluid material of carrying, can there is a certain amount of bubble unavoidably, if not in time bubble is discharged, can cause the decline of pipeline operation efficiency, even cause pipe deforming to break, common outlet valve is little in air displacement, and during exhaust easily by liquid in pipeline with Bas Discharged.
Summary of the invention
Object of the present invention is to provide a kind of air displacement greatly and the outlet valve of the diplopore of easy-to-leak liquid not.
To achieve these goals, the present invention arranges respectively ball float bracket in the both sides of valve pocket inside, and ball float is installed respectively on the slideway of ball float bracket, valve gap is set on valve body, it is corresponding with ball float that the both sides of valve gap arrange respectively exhaust port, top cover is arranged on valve gap by bolt and nut, valve gap pad and pad are set respectively between valve gap and valve body, the screw thread that valve rod passes through is spun on valve gap, seal ring is enclosed within on the valve rod of valve gap inside, gland is enclosed within on valve rod, one end of gland contacts with seal ring, the other end compresses by the pressing plate being fixed on valve gap, valve plate is connected with valve rod by bolt, in valve plate bottom, valve plate pad is set.
By above setting, the present invention adopts double Standard Valve Design, has improved the efficiency of exhaust, and two outlet valve places arrange valve gap pad, has strengthened the sealing of cavity, the outflow of liquid in pipeline while having avoided exhaust.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
In figure: 1, valve pocket, 2, ball float bracket, 3, ball float, 4, valve body, 5, valve gap, 6, exhaust port, 7, top cover, 8, valve gap pad, 9, pad, 10, valve rod, 11, seal ring, 12, gland, 13, pressing plate, 14, valve plate, 15, valve plate pad.
Embodiment
As shown in Figure 1, the present invention arranges respectively ball float bracket 2 in the both sides of valve pocket 1 inside, and ball float 3 is installed respectively on the slideway of ball float bracket 2, valve gap 5 is set on valve body 4, it is corresponding with ball float 3 that the both sides of valve gap 5 arrange respectively exhaust port 6, top cover 7 is arranged on valve gap 5 by bolt and nut, valve gap pad 8 and pad 9 are set respectively between valve gap 5 and valve body 4, the screw thread that valve rod 10 passes through is spun on valve gap 5, seal ring 11 is enclosed within on the valve rod 10 of valve gap 5 inside, gland 12 is enclosed within on valve rod 10, one end of gland 12 contacts with seal ring 11, the other end compresses by the pressing plate 13 being fixed on valve gap 5, valve plate 14 is connected with valve rod 10 by bolt, in valve plate 14 bottoms, valve plate pad 15 is set.By above setting, during gas within needing discharge conduit, rotary valve rod 10, rises its valve plate 14, and the gas in pipeline enters in valve pocket 1 under the pressure action of liquid, from exhaust port 6, discharge, along with the liquid in pipeline enters valve pocket 1, while no longer including gas in the liquid that pipeline flows into, ball float 3 moves up under the floating function of liquid, until exhaust port 6 is stopped up, reach self-sealing; While again there is gas in the liquid in pipeline, gas enters in valve pocket 1 under the pressure action of liquid, force ball float 3 to decline, leave original sealing station, gas is discharged from exhaust port 6, and ball float 3 constantly repeats above-mentioned action, and gas is constantly discharged, when needs maintenance or cleaning valve pocket 1, make valve plate 14 press valve body 4 valve rod 10 opposite spins.
