Abstract

PURPOSE: To enhance the water sealing performance of a flange by such a construction that the main packing follows up any movement of the short tube, in the axial and the radial directions, by supplying pressurized fluid to the back of the main packing with the aid of a pressurized fluid introducing means.
CONSTITUTION: The pressure P of the water in the piping acts on the incoming part i of the packing groove 25 through gaps G1, G2 as well as on the back j of the main packing 17 through an introducing hole 32 and an introducing gutter 31. The main packing 17 is given chiefly a component force K2 directed from the mid-point between i and j toward the outlet h of the packing groove, that enables to follow up fully the movement og the short tube 16 and the gap G2. Consequently, the water checking forces at the contact points e and g of the main packing 17 with the short tube's 16 outer side and No. 2 companion flange part, respectively, are increased. By the multiplying effect of these, checking of water at the h-part can be well attained.
