Abstract
The utility model discloses an air discharge valve, which is suitable for occasion where the air needs discharging such as the heating pipeline or the container for containing the hot water. The utility model is provided with a valve body, a valve cap, an air discharging seat, a floating ball, and a valve needle. The utility model is characterized in that the valve seat is arranged between the water air inlet of the valve body and the system pipeline, and is movably connected with the valve body, the valve seat is provided with a drain valve core and a travel reset spring thereof, and the lower end post of the drain hole of the drain valve core is provided with a sealing ring which is matched with the valve seat in the normally open or normally closed status. The utility model with the constructional characteristics has the advantages of simple structure, light form, convenient maintenance, etc. The function is increased, but the cost is not increased.
Description
The utility model is about a kind of outlet valve, and being applicable to hot duct or holding hot water tank needs the exhaust occasion.
Existing outlet valve major part is utilized Lever type ball float mechanism, obviously bring that outlet valve valve body shape is big, structure is also complicated, the model utility that the patent No. is 892072741 and is called " automatic control pressure vent that has gas-liquid separation chamber " with the Floater Structure setting simplify handle but adopt than the transition plate of complicated shape structure and with gas-liquid separation chamber's design, the big and high deficiency of cost of the build of outlet valve all will be improved.
The utility model purpose is that will to overcome above-mentioned prior art not enough and a kind of automatic control pressure vent with shutoff valve is provided.
This automatic control pressure vent still has valve body, valve gap, places the exhaust seat of valve gap, ball float and the needle that cooperates with exhaust seat thereof, this needle and ball float fuse, it is characterized in that being provided with between valve inleting water steam ports and the system pipeline valve seat and valve body flexibly connects, valve seat is established hydrophobic spool and stroke Returnning spring thereof, and newel post is provided with seal ring and valve seat is often opened or normally closed being sealed and matched under the weep hole of hydrophobic spool.
The automatic control pressure vent of said structure characteristics increases function but also few valve body build that increases, and simple in structure, easy to assembly in addition, cost is lower.
Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.
Fig. 1 is the utility model example structure sectional view
Wherein, 1: exhausting seal ring, 2: diversion vapour elbow, 3: exhaust seat.4: screw, 5: valve gap, 6: packing ring, 7: valve body, 8: ball float, 9: needle, 10: valve seat, 11: hydrophobic spool, 12: Returnning spring, 13: seal ring, 14: the buffering discharge orifice.
As shown in the figure, an interface is only arranged between the utility model and the system pipeline, valve body 7 is connected with pipeline by valve seat 10, valve seat 10 is connected with employing thread seal in valve body 7 present embodiments, on valve body 7 bottom surfaces, be provided with buffering discharge orifice 14 between valve seat 10 and the valve body 7, valve seat 10 is provided with hydrophobic spool 11 and stroke Returnning spring 12 thereof, newel post is provided with seal ring 13 under hydrophobic spool 11 weep holes, when sealing circle 13 and valve seat 10 are often opened and are cooperated, the steam of system pipeline enters valve body 7 by hydrophobic spool 11, when dismounting valve body 7, hydrophobic spool 11 is under Returnning spring 12 effects, make seal ring 13 and valve seat 10 normally closed being sealed and matched, the steam of system pipeline all can not be discharged, and said structure is particularly conducive to the maintenance of outlet valve.Needle 9 fuses with ball float 8, ball float 8 spheroidal structures help bearing big pressure, for ball float 8 stable elevation, as required, needle 9 can be done and pass ball float 8 structural designs, it passes ball float 8 one ends and places valve body 7 bottom surface slide guide holes, exhaust seat the upper end be provided with diversion vapour elbow 2, be beneficial to the external discharging of draining tracheae.
Claims (3)
