Description
Technical field
The utility model relates to a kind of waterway controlling valve, is specifically a kind of water tower outlet conduit aeration valve.
Background technique
At present, non-tower water feeder has become the main drainage facility of countryside and peasantry, universal each family, almost every household all use, but in these traditional water supply connecting pipelines, does not all install aeration valve.Water tank due to non-tower water feeder is made up of sheetmetal, and when the water level in water tank is emptying, casing will be inhaled flat by the negative pressure in water tank, and pump drainage so is repeatedly inhaled flat, not only reduces the working life of water tank, but also easily causes the pipe fitting of connection to leak.
Summary of the invention
The purpose of this utility model overcomes above-mentioned defect exactly, provides a kind of aeration valve, to extend the working life of water tank, ensures the safe water of resident, Leakage prevention.
Scheme of the present utility model is by upper valve body, lower valve body, spool and spring composition, its structural feature is provided with upper binding head in the upper end of upper valve body, the outside of upper binding head is provided with outside thread, the upper end of upper valve body is provided with vent, the lower end of upper valve body is provided with lower valve body, the bottom of lower valve body is provided with inlet hole, the upper end of inlet hole is provided with spool, the upper end of spool is provided with spring seat, spring seat is built with spring, the bottom of spool is provided with valve rod, the lower end of valve rod is arranged in inlet hole, the lower end of spool is provided with sealing gasket, sealing gasket is arranged on the upper end of inlet hole, the upper end of lower valve body is provided with outside thread, the lower end of upper valve body is provided with internal thread, lower valve body is arranged on the bottom of upper valve body by being threaded, seal ring is equipped with in the joint of upper and lower valve body.The ectosome of lower valve body is shaped with outside thread.During use, aeration valve is arranged on the upper end of water tank, when the water level in water tank reduces, the spool of aeration valve will be inhaled and open by the negative pressure produced in water tank, and tonifying Qi in trend water tank, water tank would not be flat by suction.
The utility model structure is simple, and processing is convenient, and using effect is good.
Be described in further detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
