Description

Vertical floating air exhaust valve

The utility model relates to the float outlet valve, refer to especially a kind of with spring reset and flap and the vertical float outlet valve of exhaust port on same axis, be applicable in hot and cold water pipeline or the heating pipe-line system as automatic exhaust valve.

Gong Ying automatic control pressure vent in the market exists that volume is big, Heavy Weight, easy defective such as leak, though the individual product volume is little, also exists part fragile, is not closed completely, phenomenon such as easily leak.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of automatic control pressure vent that improves structure is provided, and makes its volume small and exquisite, and exhaust work is reliable, increases the service life.

Used technological scheme is with valve body, float, valve gap, in the float outlet valve for the major part composition such as exhaust nozzle, the guide sleeve on band lower flange limit is housed in the offset hole of its valve gap upper-end surface, be connected with exhaust nozzle with its upper external screw thread, the flap that can move along axis is housed in the inner chamber of guide sleeve, in the blind hole of flap upper end sealing gasket is housed, the epimere of pressure spring is housed in the blind hole of lower end, described flap, sealing gasket, exhaust port in the center line of pressure spring and the exhaust nozzle is altogether on a center line, on this center line and the float, following movement direction parallels, described pressure spring is by support on the flange edge that is hung on guide sleeve and spring support plate institute support, one of connecting sheet end has slotted hole to be connected with float through clothes-hook, the other end has outer wing plate and interior wing plate, outer wing grillage is in the square hole of support dual-side, and interior wing plate is placed between the flange edge of the flange edge of guide sleeve and flap.

The inner chamber of described guide sleeve is that interior hexagon, associated flap outer cylindrical body are the garden cylindricality, and the two is gapped cooperation.

Vertical float outlet valve of the present utility model, volume is small and exquisite, compact, reliable in action, flexible, automatic vent was smooth and easy when pressure was high, and sealing was tightly water-tight, economical and practical when pressure was low.

Now in conjunction with the accompanying drawings with preferred embodiment.

Fig. 1 is the utility model embodiment's a front section view.
