Abstract
The utility model relates to an automatic air outlet valve which is used on a hot water heating system branch pipe, the automatic air outlet valve belongs to a mechanical valve type. A valve body of the air outlet valve is a vertical structure, and the valve body appearance takes polygon prism shape, cylinder shape, taper shape in turn from the center of the valve body to the two ends of the valve body, the lower portion of a corresponding valve chamber takes conical funnel shape, a lever of a hanger float in an air exhausting device takes a T shape, the outer end of an exhaust nozzle is provided with a safety screw. The air exhausting device of the air outlet valve has a higher safety factor, due to a multi-corner appearance of the valve body, dismounting is led to be more convenient when the valve body is assembled and repaired, and the valve body has the advantages of small size and beauty appearance.
Description
Technical field:
The utility model relates to a kind of hot-water heating system lateral automatic control pressure vent, belongs to the mechanical valve class.
Background technique:
Present known hot-water heating system lateral automatic control pressure vent is of a great variety, but generally belongs to two classes.One class is horizontal, and this kind structure is easily accumulated solid sedimentation dirt, makes it malfunctioning and its moving element is produced pad card phenomenon.There is above-mentioned bad phenomenon equally in another kind of vertical garden column.
Summary of the invention:
Goal of the invention of the present utility model provides a kind ofly can stop the automatic control pressure vent that above-mentioned disadvantage, automatic exhaust device have higher safety factor.
The technological scheme that realizes the foregoing invention purpose is: this outlet valve is made up of valve body, valve gap, automatic exhaust device, valve body is a vertical structure, its profile is multi-edge column-shaped, cylindrical, conical from the stage casing successively to two ends, and corresponding valve pocket its underpart is the conical funnel shape; The lever of hanging float in the automatic exhaust device is T-shaped; Check screw is equipped with in exhaust nozzle outer end.
The utility model is owing to designed conical funnel shape lower chamber, therefore solid deposits easily skids off valve pocket and enters pipeline, stopped the pad card phenomenon that solid deposits produces float, dismounting when many prismatics valve body is convenient to installation and maintenance, the T-shaped lever has overcome the float suspension ring and has come off and make the malfunctioning shortcoming of automatic exhaust device, and the setting of check screw has improved the safety factor of automatic exhaust device greatly.This outlet valve also has characteristics such as volume is little, beautiful shape simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Provide embodiment of the present utility model in conjunction with the accompanying drawings.Its parts of the described automatic control pressure vent of this embodiment constitute comprise that valve body 1, float 2, seal ring 3, check screw 4, exhaust nozzle 5, valve gap 6, rubber are stifled 7, extension spring 8, suspension ring 9, cross bar 10.Valve body 1 is a vertical structure, and its profile is multi-edge column-shaped, cylindrical, conical from the stage casing successively to two ends, and corresponding valve pocket its underpart is the conical funnel shape.Valve gap 6 buckles mode by O type rubber seal 3 with spiral shell and valve body 1 upper end is fastenedly connected, and valve body lower end is provided with the external screw that is connected with pipeline.Automatic exhaust device is stifled 7 by float 2, exhaust nozzle 5, rubber, extension spring 8, suspension ring 9, lever 10 constitute, exhaust nozzle level entad is contained on valve gap 6 sidewalls, T-shaped lever 10 is connected with the tubular body portion of this nozzle 5 in putting in valve pocket in the elastic prestress mode by extension spring 8, rubber stifled 7 is housed between the two, by suspension ring 9 supending roll type float 2 is housed on this lever 10, check screw 4 is equipped with in exhaust nozzle 5 outer ends.
Its design principle of automatic exhaust device of the present utility model is: the float 2 of certain mass certain volume is hung on T-shaped lever 10, no working-medium water or water level do not reach certain liquid level in valve pocket, or in running,, the gas accumulation in the pipeline make its liquid level drop to certain position because replacing away the water in the chamber in the valve pocket, then leave behind at the following lever 10 of float 2 weight effects, the stifled 7 inclination several angles of glue this moment are with exhaust nozzle 5 air inlet open automatic vents, liquid level rises thereupon, float 2 come-ups, when liquid level reaches certain position, then float suspension ring 9 withstand valve gap 6 and are spacing, this moment, lever 10 was horizontal, and glue stifled 7 exhaust nozzle 5 suction ports that set back block realization and close automatically.Extension spring 8 is fixed together lever 10, glue stifled 7 and makes it to have realized that elastic prestress is connected with the tubular body portion of nozzle 5, and then has realized opening or closing automatically of stifled 7 control exhaust nozzle 5 suction ports of glue.The purpose of check screw 4 is equipped with in exhaust nozzle 5 outer ends, is for guaranteeing that the user uses and can guarantee safety when keeping in repair that it is perfectly safe to accomplish.Under normal circumstances check screw 4 unclamps, and makes nozzle 5 unimpeded, in case accident occurs then check screw 4 is tightened and nozzle 5 is closed.
