Packing member for sealing pipe

The present invention relates to a packing member for sealing a pipe to receive the pipe in an internal hollow hole, having a hollow body inserted inside a hollow housing, so as to prevent a fluid flowing inside a pipe from being leaked out. According to the present invention, a curved part protruding towards the internal central part of the hollow body is formed in both ends of the hollow body, so a fluid reception part which is a space to receive the fluid is formed between the curved part and the internal surface of the body. To allow the fluid to be supplied in the fluid reception part even if the end part of the curved part is in contact with the internal surface of the body by a pipe inserted inside the body, a first fluid hole to communicate with the fluid reception part is formed in the end part of the curved part. According to the present invention, since the packing member includes the fluid reception part which is a space to receive the fluid leaked in an initial stage, the fluid is absolutely prevented from being leaked out. Moreover, as the fluid leaked in the initial stage is received in the fluid reception part, the pressure due to the fluid is increased, such that sealing is reinforced to continuously prevent the fluid from being leaked out. Moreover, since the fluid reception part is formed in both ends of a packing, sealing can be efficiently maintained.

Sealing member and pipe

PURPOSE: A sealing member and a pipe employing the same are provided to ensure high deformation resistance and installation stability because a hard guide frame and soft rubber are integrated through insert molding. CONSTITUTION: A sealing member(10) comprises a ring-shaped hard guide frame(20), a soft watertight ring(30), and a smoothly deformable part(22). The guide frame has a tapered surface on the inner perimeter and a joint portion. The watertight ring is coupled to the guide frame to cover the joint portion and has inner and outer tails(31,32) formed at an interval. The smoothly deformable part is formed on the leading edge of the guide frame in the shape of groove, slot, or aperture.

Cast-iron pipe coupling for low pressure application - has conical housings for pipe ends with V=section seals and stop lug

The cast-iron pipe coupling accommodates straight tube at both ends. The coupling has conical housings at each end in which are 'V' shaped or chevron sealing rings. Between the two halves of the coupling is a spigot (8) which serves as a stop for the two tubes T1,T2). When the tube (T1) is inserted in the coupling, the chevron sealing ring is deformed to form a water-tight seal. The assembly has sufficient flexibility to allow each tube to be introduced at an angle not exceeding 7 degrees with the axis of the coupling, without affecting the integrity of the joint. These couplings are for pressures up to 5bar.

ABSTRACT OF THE DISCLOSURE There are disclosed two embodiments of an apparatus for releasably latching the lower end of a tubing string within the bore of an upstanding well conduit by means of latching parts adapted to be received in latching position beneath a shoulder in the bore of the well conduit. The latching parts are locked in latching position by locking means which is engageable and releasable in response to manipulation of the well string. The latching parts are moved into unlatching position, upon release of the locking means, without necessity of sliding contact between the latching parts and the shoulder. There are also disclosed two embodi-ments of a seal ring clamped within a groove about a stinger portion of the apparatus for sealably engaging the bore of the well conduit.

Concrete pipe joint seal - has U-shaped cross section ring with different thickness lips on surfaces of radially inward rib

The sealing ring is intended for use with joints in ceramic or concrete pipes and is suitable for fluid pressures of up to two bars. The sealing ring has a U-shaped cross-section with a rib (3) extending radially inwards. The rib (3) has a thin lip (4) on its upper surface and a thicker lip (11) on its lower surface. The U-shaped part of the ring fits over the edge of the bore of the female pipe (1). The deformation of the arms (8, 10) creates radial forces (f1, f2) which ensure a good seal against the pipe walls. The male pipe (5) deforms the rib (3) as it is inserted into the end of the pipe (1). The thin lip (4) is pressed against the wall of the pipe (5) and the thick lip (11) presses the arm (2) against the bore of the pipe (1).

Joint sealing flush pipe for lavatory pan - has concentric barrel shaped and tapering elastomeric lips

The flexible joint is made from an elastomeric material and has an annular rim (1) with a sealing lip (3) extending in the axial direction. This lip has a barrel shaped longitudinal section, curved outwards to seal and grip inside the water closet pan entry (4). The rim (1) fits flush against the end (7). Another sealing lip (8) is moulded inside the curved lip, concentric with it and extending in the same axial direction. This lip is angled inwards to form a cone and is used to seal round the outside of the flush pipe (9). Misalignment over a range of sizes can be accomoodated.
