Easily influence the discharge of air.Due to the setting of the first elongated slot in floating body outer peripheral sidewall, enable air into valve chamber along
First elongated slot bypasses floating body, so as to improve the velocity of discharge of air.
The utility model may further be provided are as follows: the other end of first elongated slot extend to the floating body other end it is corresponding into
At gas channel.
By adopting the above technical scheme the advantages of is: when floating body is in extreme lower position, the air of inlet channel can pass through
The other end of first elongated slot is around floating body discharge, to further improve the velocity of discharge of air.
The utility model may further be provided are as follows: the gas channel of crossing includes being set to the first cavity internal perisporium
Second elongated slot, which is at least one and one end extends at the primary sealing area, the other end of the second elongated slot
The second opening is provided at the secondary sealing area.
By adopting the above technical scheme the advantages of, is: since the second sealing of its plug when floating body rises with water level can
It is inserted into the first cavity, when the second sealing is inserted into the first cavity (the second sealing does not contact sealing also with primary sealing area)
When, gap between the two is smaller, is easy to influence the discharge of air.Due to the setting of first the second elongated slot of cavity internal perisporium, make sky
Gas can bypass the second sealing along the second elongated slot, so as to improve the velocity of discharge of air.
The utility model may further be provided are as follows: be formed with annular on first sealing and the second sealing
Sealing ring.
By adopting the above technical scheme the advantages of, is: can effectively improve between the first sealing and secondary sealing area and
Contact leakproofness between second sealing and primary sealing area.
