Abstract
The utility model discloses an automatic exhaust valve, relating to a mechanical exhaust valve used for a water circulating system. The floating body of the automatic exhaust valve is provided with a guide post with an exhaust vent, and a valve cover is provided with a guide sleeve having clearance fit with the guide post. The disadvantages that the existing exhaust valves have poor sealing property, and sealing elements are easy to be broken are overcome. The utility model has the advantages of simple structure, favorable sealing effect, convenient maintenance and replacement, etc.
Description
The utility model relates to a kind of mechanical outlet valve that is used on the water circulation system.
Be used for the venting gas appliance of common hot water heating circulatory system blowdown piping gas, known venting gas appliance is an automatic control pressure vent, and valve body top is provided with exhaust port, body cavity has a buoyancy aid, utilize Sealing and exhaust port sealing on the buoyancy aid, when having air to get rid of in the pipeline, buoyancy aid breaks away from sealing by deadweight, exhausting air, treat air emptying in the pipeline, water level rises in the valve body, and the buoyancy aid come-up is resealed, but the excessive phenomenon of water appears in this valve seal weak effect sometimes.China's utility model patent discloses a kind of automatic vent sealing valve (85204220), though the cone seal mode has been adopted with valve body in the buoyancy aid upper end, during sealing, matching surface easily misplaces, and effect is still not good, and sealing surfaces is processed relatively difficulty.
The purpose of this utility model is to provide the automatic control pressure vent of a kind of simple in structure, good sealing effect, convenient maintenance and replacement.
The utility model is made up of valve body, valve gap, guide pillar, guide pin bushing, seal ring, buoyancy aid, its guide pillar has exhaust port, seal ring is housed is packed on the buoyancy aid, guide pin bushing is installed on the valve gap, and guide pillar, guide pin bushing are Spielpassung, and guide pin bushing lower end surface and seal ring are realized sealing.This valve is loaded on the water circulating pipe, and when in the pipeline gas being arranged, buoyancy aid is opened exhaust port by its deadweight, and air is discharged by the exhaust port on the guide pillar.After the air emptying, water flows into valve body buoyancy aid is floated, and guide pillar moves up along guide pin bushing, closes exhaust port, the seal ring on the while guide pillar and the lower end surface closure of guide pin bushing, thus realize sealing.
The utility model has the advantages that 1, simple in structure, easy to assembly, Sealing is changed easily; 2, owing to adopted the double seal of guide pillar and guide pin bushing Spielpassung and guide pillar seal ring and guide pin bushing lower end surface, improved sealing effect greatly, safe and reliable; 3, under different pressures, work, rely on the counterweight of regulating buoyancy aid, satisfy the back pressure requirement of different levels.
Accompanying drawing is the automatic control pressure vent structural representation.
Implementation example: as shown in drawings, on the surface of ball float 9, be welded with nut 8, guide pillar 1 has inlet hole A, the lower end car has screw thread, is contained on the nut 8 behind suit seal ring 11 and the packing ring 7, and guide pin bushing 2 outer surface cars have screw thread, it is contained in the center hole of valve gap 3, and guide pillar 1 is loaded in the guide pin bushing 2 and with spacing pad 12 locate, in the inner chamber with valve bodies 10 of packing in the lump such as ball float 9 and guide pillars 1, valve gap is loaded on the valve body 10 with nut 4, bolt 5 and sealing gasket 6.
Claims (2)
1, a kind of automatic control pressure vent is made up of valve body, valve gap, guide pillar, guide pin bushing, buoyancy aid, it is characterized in that guide pillar has exhaust port, is loaded on the buoyancy aid, and the guide pin bushing that is Spielpassung with guide pillar is housed on the valve gap.
2, automatic control pressure vent according to claim 1 is characterized in that guide pillar is equipped with the seal ring that is secondary seal with the guide pin bushing lower end surface.
