Abstract
The utility model relates to a corrugated pipe type water drain valve, comprising a valve body, a protective sleeve, a corrugated pipe, the inflation liquid, a valve seat and a valve core. The valve seat, the protective sleeve are arranged in the valve body; the corrugated pipe is arranged inside the protective sleeve; the inflation fluid is arranged inside the corrugated pipe. The utility model is characterized in that the protective sleeve is arranged on the valve seat; a hole is arranged on the protective sleeve; an end of the valve core is long and protrudent and arranged in the valve seat; a flexible sealing ring is arranged on an opening of the valve seat. The utility model has the advantages of good sealing and simple structure.
Description
(1) technical field:
The utility model relates to a bellow type drain valve, is used to heat and the equipment of the network that heats.
(2) background technique:
Present existing drain valve such as notice of authorization number are the bellow type drain valve of CN2371399Y, and it is made up of bellows, bellows chamber, adjusting nut, valve rod, valve body, valve seat, spool, Decompression valves.Its spherical valve core is the line contact with contacting of valve seat, after use a period of time, and the valve rod skew, the spool wearing and tearing easily cause leakage, and, its complex structure, fabricating cost is higher.
(3) summary of the invention:
The utility model purpose is exactly the above defective that will solve prior art, provides a kind of long-time use also can not reveal, and simple in structure, the drain valve that fabricating cost is lower.
The technical solution of the utility model is: this valve is made up of valve body, protective casing, bellows, swelling liquid, valve seat, spool.Valve seat, protective casing are located in the valve body, are provided with bellows in the protective casing, and swelling liquid is arranged in the bellows; it is characterized in that protective casing is located on the valve seat, protective casing is provided with the hole; the spool end is elongated outstanding, is positioned at valve seat, and the valve seat mouth is provided with flexible seal ring.
Advantage of the present utility model is:
1, the utility model spool end is elongated outstanding, is positioned at valve seat, is used to prevent the spool skew, and the valve seat mouth is provided with flexible seal ring, increases its sealing, even long-time the use can not revealed yet;
2, the utility model is made up of valve body, protective casing, bellows, swelling liquid, valve seat, spool, and it is simple in structure, and fabricating cost is lower.
(4) description of drawings:
Fig. 1 is the utility model structural representation.
(5) embodiment:
