Abstract
The utility model provides an automatic exhaust valve, comprising a valve body (5) having an upper end with a valve cap (9) and a sealing ring (1) arranged between the valve body (5) and the valve cap (9). The automatic exhaust valve is characterized in that the valve body (5) is provided with an exhaust port (10) communicated with the outer part of the valve body (5), and a floater (4) is arranged in the valve body (5); the upper end of the floater (4) is connected with one end of a lever (3), and the other end of the lever (3) corresponding to the inner end of the exhaust port (10) is provided with a sealing gasket (2); the middle fulcrum of the lever (3) is arranged in the valve body (5). The utility model has the advantages of small size, convenient operation, safe use, etc.
Description
The utility model relates to a kind of automatic control pressure vent.
The existing outlet valve that is used for liquid line, the outlet valve in the hot-water heating pipeline particularly, mainly be to adopt manual exhaust valve or stop valve that cool air in the pipeline or water vapor are carried out exhaust, the method of the artificial venting of this employing, waste time and energy, then will influence heating temperature as untimely cool air in the pipeline is discharged, certain customers utilize manual exhaust valve to steal the hot water use from heater unit in addition, this not only wastes water, and the safe operation of boiler is affected.
For overcoming the shortcoming of existing manual exhaust valve (or stop valve), but the utility model provides a kind of automatic vent, and good exhaust effect is water-tight, can not the people be the vertical automatic exhaust valve that discharges water.
Technical solution of the present utility model is: a kind of automatic control pressure vent, by valve body ［ 5 ］ upper end valve gap ［ 9 ］ being housed forms, between valve body ［ 5 ］ and the valve gap ［ 9 ］ seal ring ［ 1 ］ is housed, it is characterized in that: valve body ［ 5 ］ is provided with the relief opening ［ 10 ］ that is interlinked to the outside with valve body ［ 5 ］, be equipped with in the valve body ［ 5 ］ cursory ［ 4 ］, cursory ［ 4 ］ upper end joins with an end of lever ［ 3 ］, sealing gasket ［ 2 ］ is equipped with in the inner corresponding position of the other end of lever ［ 3 ］ and relief opening ［ 10 ］, and the fulcrum at lever ［ 3 ］ middle part is located in the valve body ［ 5 ］.
The sealing case that described cursory ［ 4 ］ process for PVC.
The utility model with prior art compare have simple in structure, volume is little, esy to use, safe and reliable, can be at any time with advantages such as the gas that produces in the pipeline emit.
Accompanying drawing 1 is the utility model embodiment's a elevation view.
Accompanying drawing 2 is the utility model embodiment's the diagrammatic sketch of bowing.
Below in conjunction with description of drawings embodiment:
