摘要： A method for manufacturing a resin pipe joint with a joint body includes the following steps. Preparing a mold and a supply device configured to supply molten resin. The mold includes a first mold for an outer shape of the joint body and a second mold for an inner shape of the joint body. Combining the second mold with the first mold to form a cavity, into which the molten resin is injectable, inside the mold. Supplying the molten resin to the cavity in the mold. Solidifying the molten resin in the cavity after stop of the supply of the molten resin from the supply device. The second mold has a gap that connects the cavity to a discharge space outside the cavity and allows gas to flow.

摘要： Sealing ring of an elastic material, for use in a pipe coupling in which the ring is placed in a radially inwardly open peripheral groove and is retained in said groove by means of a supporting ring(6) which sealing ring in each radial cross-section is the shape of an inwardly open, essentially rectangular trough with a circular bottom (2), a projecting lip (8) being provided which runs inwards at an angle from the end of the first circumferential wall of the trough, the free end of which lip lies at a radial distance from the axis of symmetry of the ring which is smaller than the external radius of the push-in end part of a pipe to be coupled and at the end of the second side wall of the trough, the free end of which lip lies at a greater distance from the above-mentioned axis than the free end of the first lip, the second lip being provided with a run-on face (10) which runs from a point near the bottom of the lip in the direction of that axis to an end point which lies at a distance from the axis which is smaller than the distance between the axis and the free end of the second lip, while the trough is of a depth which is greater than the radial thickness of the supporting ring, so that in the fitted state and with a push-in end part pushed through the ring an open space (14) is present between the supporting ring and the outwardly facing faces of the first and second lip.

摘要： The present invention is a water conduit connector for an animal water supply system. The connector has a body which receives adjacent ends of water conduit sections. Inserts are positioned into the connector body and define pockets for positioning sealing o-rings. The inserts, o-rings, and connector body receive the conduit section ends, with the o-ring being compressed to form a sealing contact with the outer surface of the water conduit. The insert includes a ridge which engages an internal groove of the connector body to securely fasten the insert within the connector body. Tapered portions of the insert and connector body facilitate the entry of the insert into the connector body. The connector facilitates manufacture because no sonic welding is needed to complete the connector body and form the pockets in the connector body which house the o-rings.

摘要： A method of manufacture of a sealing body for a pipe joint comprising a retaining ring of thermoplastic material, which is to be fastened on the end portion of a pipe part, and a sealing ring of thermoplastic material, preferably thermoplastic rubber, bonded to the retaining ring. The retaining ring is first moulded by injection moulding and then the sealing ring is moulded by injection molding in a second mould cavity which is partly bonded by a portion of the retaining ring. The first mould cavity is bounded by two mould cavity surfaces movable relative to one another. When the first mould cavity is opened, the retaining ring remains on one mould cavity surface and is subsequently placed back against the other mould cavity surface. During injection moulding of the sealing ring the mould cavity may be sealed at the transitions from the surface portion of the retaining ring to the adjoining mould cavity surfaces by an annular lip and an annular ridge respectively. A sealing ring and a following retaining ring may be moulded practically simultaneously in first and second mould cavities spaced apart in one and the same mould.

摘要： A composite gasket for forming a seal between a pipe bell 52 and a spigot 58 comprises a major portion 12 of non-elastomeric plastic material and a minor portion 14 of elastomeric material. The minor portion is axially encased by the major portion. The minor portion includes a sealing lip 16 extending radially inwardly from the major portion. The composite gasket can be manually inserted within a preformed grooved bell or the grooved bell can be formed over the gasket while the gasket is mounted on a mandrel. The composite gasket is particularly useful with relatively large diameter pipe systems.

摘要： A dual function gasket adapted for insertion into a suitable groove formed in the bell of an associated pipe includes an annular gasket body made of a resilient material. The body terminates radially inwardly in a leading lip and a pressure activated sealing lip spaced rearwardly therefrom. An annular groove is provided in the gasket body and an annular locking ring may be selectively inserted into the groove. The ring is made of a material harder than the gasket body and is inserted into the groove when a high pressure seal is desired. The ring may be removed when only a low pressure seal is desired.

摘要： A resilient gasket is disclosed which includes an annulus of generally U-shaped cross sectional configuration having a circular, arched, radially outwardly positioned base, a first, thin, forward wall extending radially inwardly from the base, a second relatively thick, rearward wall extending radially inwardly from the base, the forward wall and the rearward wall defining a circular, radially inwardly open, retaining ring receiving groove therebetween, the width of the groove being greater than the combined thickneses of the forward and the rearward walls. The forward wall and the rearward wall each terminate radially inwardly in a slanted, forwardly facing lip to facilitate sealing engagement with the spigot end of a section of pipe. The lip of the forward wall serves to center and to wipe the exterior periphery of the spigot end and the lip of the rearward wall serves to seal against the spigot end.

摘要： The mandrel uses a single anchoring groove in order to fixedly mount the forming and sealing element thereon for subsequent passage of a heated thermoplastic pipe end thereover. The forward wall of the anchoring groove may be directed radially outwardly or may be inclined rearwardly in order to abut the sealing portion of the element. The sealing portion fills the anchoring groove while the trailing wedge-shaped end fits into a small recess to avoid "fish-mouthing."
摘要翻译：心轴使用单个锚定槽，以便在其上固定地安装成形和密封元件，以便随后在其上通过加热的热塑性管端。锚定槽的前壁可以径向向外指向或可以向后倾斜以便抵靠元件的密封部分。密封部分填充锚定凹槽，而后楔形端部装入小凹槽中以避免“鱼嘴”。
