Abstract
The utility model discloses an automatic drain valve, which comprises a valve body, wherein a cavity is formed in the valve body; a spring seat is installed inside the cavity; a rubber valve is clamped at the upper end of the spring seat; the rubber valve is sheathed with a spring; a cover is installed at the upper end of the rubber valve; a gap is formed between the lower end of the cover and the valve body; an O-shaped seal ring is installed in the gap; a ring-shaped groove is formed on an inner wall of the valve body at the upper end of the cover; a check ring is clamped in the groove; the check ring is jointed with the cover; a through hole is formed at the middle part of the cover; the rubber valve penetrates through the through hole and extends out of the cover; and the valve body is a hollow cylinder provided with a plurality of steps. The automatic drain valve can be opened and closed effectively along with the changes of the pressure by adopting the structural manner that a pressure component and a spring are installed inside the valve body, can achieve the automatic water drainage function, can greatly improve the mechanical strength and the tightness, and cannot go wrong when being used for a long time.
Description
Technical field:
The utility model relates to valving.A kind of specifically automatic drain valve.
Background technique:
Automatic drain valve is a kind of annex supporting with pressure piping, it is used to discharging water automatically of pressure piping or water storage equipment, and it is the principle work that utilizes float and pressure reduction.But existing automatic drain valve, its mechanical strength and tightness all have deficiency, and therefore imagination provides a kind of new structure to improve.
Summary of the invention:
The purpose of this utility model provides a kind of automatic drain valve, mode of structure by setting pressure parts and spring in the valve body can effectively open and close with pressure change, realizes discharging water automatically function, its mechanical strength and tightness all strengthen greatly, and long-term the use can not go wrong yet.
The technical solution adopted in the utility model is:
A kind of automatic drain valve, comprise valve body: valve inner has cavity, cavity inside is equipped with spring seat, and the spring seat upper end is installed with rubber valve, and rubber valve is set with spring outward, the rubber valve upper end is equipped with lid, have the space between lid lower end and the valve body, the O RunddichtringO is installed in the space, the valve interior wall that covers end has annular groove, be installed with back-up ring in the groove, back-up ring is fitted with lid; Have through hole in the middle of the described lid, rubber valve passes through hole and stretches out lid.
Described valve body is the hollow cylinder with multistage step.
Advantage of the present utility model is:
The utility model can effectively open and close with pressure change by the mode of structure of setting pressure parts in the valve body and spring, realizes discharging water automatically function, and its mechanical strength and tightness all strengthen greatly, and long-term the use can not go wrong yet.
