Abstract: A balance ratio for a stationary seal ring is designed to allow a seal face to be opened when, with a rotary seal ring at standstill, steam of a predetermined pressure is supplied to an endo-fluid region while a sealing-fluid region is brought into an exhausting state. On the other hand, an O-ring constituting a secondary seal portion is retained by a groove formed in a flange portion of a seal case, thereby preventing a force on the O-ring from affecting the stationary seal ring even when the steam is supplied to the endo-fluid region.

Abstract translation: 固定密封环的平衡比被设计成允许密封面打开，当旋转密封环处于静止状态时，将预定压力的蒸汽供应到内流体区域，同时使密封流体区域进入 疲惫的状态。 另一方面，构成二次密封部的O形环由形成在密封壳体的凸缘部中的槽保持，从而即使在供给蒸汽时也防止O形环上的力影响固定密封环 到内流体区域。

Abstract: A mechanical non-contact gas seal including a rotary scaling ring and a stationary sealing ring that is engaged and held in an inner periphery of a seal case by means of O-rings so as to move in an axial direction thereof. The O-rings engage with the outer periphery of the stationary sealing ring and come in press contact with the inner periphery of the seal case to seal a gap between the stationary sealing ring and the seal case while allowing the stationary sealing ring to move in an axial direction. A resin coating of a thickness in the range of 5 to 100 μm is formed on the inner periphery of the seal case at least within a range in which the O-rings relatively move with the movement of the stationary sealing ring.

Abstract: The present invention provides a static pressure type non-contact gas seal which, even when supply of seal gas 6 to the space between sealing end surfaces 3a and 4a has stopped unexpectedly, can be safely used with no possibility that the sealing end surfaces 3a and 4a collide severely against each other and consequently the sealing end surfaces 3a and 4a are damaged or destructed. In this static pressure type non-contact gas seal, the seal gas 6 is supplied to the space between the sealing end surfaces 3a and 4a from a seal gas passage 5, thereby generating an opening force that acts on the stationary sealing ring 4 in a direction that the space between the sealing end surfaces 3a and 4a is opened. An annular-spaced back pressure chamber 25 blocked by two O-rings 12 and 13 is formed between the facing peripheral surfaces of a seal case 1 and the stationary sealing ring 4, to introduce the seal gas 6 to be supplied to the seal gas passage 5 into the back pressure chamber 25, thereby generating a closing force that maintain the balance with the opening force, as a back pressure acting on the stationary sealing ring 4. A spring is not used as a means for generating the closing force.
