摘要： A liquid flow control device includes an annular housing having an inlet for liquid in one periphery of the housing and an outlet for liquid in the other periphery. An annular block of water swellable material is located in the housing. A layer of sealing material encircles the annular block on the side thereof adjacent the inlet to close the inlet when the block is swollen through contact with the liquid.

摘要： A tube coupling having a throughway open at one end to receive a tube end, an annular groove encircling the throughway at a location spaced from said open end and an annular flexible sealing washer mounted in the groove and having an inner peripheral portion which projects through the open mouth of the groove to engage an outer surface of a tube which is a close fit in the throughway. The groove has one side nearest the open end of the throughway which lies in a plane generally transverse to the throughway to limit flexing of the inner part of the sealing washer towards the open end of the throughway and an opposite side of which is relieved at the mouth of the groove to allow the inner part of the sealing washer to take up a curvature in being deformed by forcing a tube through the washer. Thus the resulting stretching of the inner part of the washer by the tube provides a seal between the washer and tube and fluid pressure on the side of the sealing washer facing into the coupling body enhances the seal between the washer and tube.

摘要： The disclosure relates to a tube coupling comprising a coupling body having a throughway open at one end of the body to receive a tube. A collet is located in the throughway having an annular element and at least one radially resilient finger extending axially from the element toward said open end of the throughway. The coupling body has a stop face directed along the throughway axis away from said open end and the distal end of the finger has on its inner side a projection to engage a feature on the tube and on its outer side a first, axially facing abutment directed towards the open end of the throughway to engage with the stop face and a further, radially facing abutment engageable with the coupling body when the axially facing abutment engages the stop face to constrain the distal end of the finger against radial outward movement and thereby to prevent release of the projection on the finger from the feature on the tube and release of the tube from the coupling body.

摘要： The disclosure relates to a tube coupling comprising a coupling body having a throughway open at one end to receive a tube, the diameter of the throughway increasing towards said open end at a first step to form a first enlarged diameter portion to receive a tube and at a second step to form a second, further enlarged diameter portion to receive a tube locking device to hold a tube in the coupling body. A thin wall sleeve has one end engageable in the throughway and the other end engageable in a tube to be located in the coupling body so that, in use, the sleeve extends from the tube passed the first step into the throughway. The end part of the tube in the throughway is engaged by a seal located in the throughway to prevent ingress of fluid between the sleeve and throughway.

摘要： A tube coupling comprising a coupling body having a throughway open at one end to receive a tube extending into the throughway. A collet is located in the open end of the throughway for holding the tube in the throughway comprising an annular head located outside the throughway and having a plurality of arms extending into the throughway and terminating in enlarged heads. The inner side of the throughway and the outer side of the tube have parallel tapered cam surfaces which reduce towards the open end of the throughway and the collet heads have inner and outer faces which are parallel to one another and to the tapered cam surfaces and engage therewith such that the heads are subjected solely to compression in resisting withdrawal of the tube from the throughway.

摘要： A liquid flow control device has a port or passageway through which liquid flow is to be controlled. A body of a liquid swellable material is located in the port or passageway having an upstream side and a downstream side in relation to the direction of liquid flow through the port or passageway. A layer of sealing material is provided on the upstream side of the body to prevent contact of that side of the body with the liquid when the body is swollen to close the port or passageway whilst allowing contact of the downstream side of the body when the body is in the non-swollen condition allowing liquid flow through the port or passageway.

摘要： A tube coupling has a coupling body with a throughway open at one end to receive an end portion of a tube. A seal encircles the throughway to seal with the periphery and end of the tube and a cap is mounted on the body having a tube locking device rotatably mounted in the cap to engage and hold the tube in the cap. The cap and body have interengaging means which guide the cap on the body in an axial direction along the body with rotation of the cap from a first position in which a tube can be inserted through the cap and into the seal in the throughway and retained by the locking device and a second position advanced along the coupling body from said one end in which the tube end is held positively in engagement with the seal in the throughway. The locking device engages via a ring with the coupling body to resist rotation of the locking device with respect to the body whereby rotation of the cap between said the first and second positions does not cause the tube to rotate.
