摘要： A moulded electrofusion fitting for connection to a plastics pipeline comprises a hollow body formed with a tubular opening that has a longitudinal axis and is adapted to receive and end of the pipeline as a close sliding fit. An electrofusion element is formed in the internal surface in the opening, spaced from its end. Fingers are on the end of the opening, circumferentially spaced around the opening and separated by slots between them. Cam surfaces in the form of ribs are defined on the fingers, and a grip ring is received on the fingers and includes wedge elements in the form of grooves. These are adapted to fit the ribs so that, when a pipeline is inserted in the opening and the grip ring is rotated about said axis, the ribs and grooves engage to press the fingers radially inwardly against the reaction of the grip ring, whereby said pipe is gripped by said grip ring and centralized in the opening. The grip ring may be integrated with a terminal pin, a bayonet slot of the grip ring accommodating the terminal pin, a shroud boss formed on the grip ring around the base of the bayonet slot.
摘要翻译：用于连接到塑料管道的模制电熔配件包括形成有管状开口的中空本体，其具有纵向轴线并且适于以紧密滑动配合接收和结束管道。一个电熔体元件形成在开口的内表面上，与其端部间隔开。手指位于开口的末端，围绕开口周向间隔开，并在它们之间被槽间隔开。形状为肋的凸轮表面限定在指状物上，手指上夹着一个夹环，并包括凹槽形式的楔形元件。这些适于装配肋，使得当管道插入开口中并且夹环围绕所述轴线旋转时，肋和槽接合以径向向内挤压手指以克服握环的反作用力，由此所述管被所述夹环夹紧并集中在开口中。夹环可以与端子销一体，夹环的卡口槽容纳端子销，形成在卡环周围卡口槽底部的护罩凸起。

摘要： A moulded electrofusion fitting (10) for connection to a plastics pipeline, comprises a hollow body (16) formed with a tubular opening that has a longitudinal axis (82) and is adapted to receive an end of the pipeline as a close sliding fit. An electrofusion element (22) is formed in the internal surface (52c) in the opening, spaced from its end (52b). Fingers (52) are on the end of the opening, circumferentially spaced around the opening and separated by slots (53) between them. Cam surfaces in the form of ribs (60) are defined on the fingers, and a grip ring (50) is received on the fingers and includes wedge elements in the form of grooves (62). These are adapted to fit the ribs so that, when a pipeline is inserted in the opening and the grip ring is rotated about said axis, the ribs and grooves engage to press the fingers radially inwardly against the reaction of the grip ring whereby, said pipe is gripped by said grip ring and centralised in the opening. The grip ring may be integrated with a terminal pin (24), a bayonet slot (106) of the grip ring accommodating the terminal pin, a shroud boss (27′) formed on the grip ring around the base of the bayonet slot.

摘要： A tapping tee assembly (10) comprises an integrally moulded saddle (12), body (14) and socket (16). The tapping tee assembly can be mounted on a pipeline thereby enabling a cutter to travel through the body of the fitting in order to cut a hole in the pipeline. The saddle (12) is provided with a saddle-shaped electrofusion element mat (18) and the socket (16), which is integral with the body (14) and in fluid connection with the axial bore (20) of the body, is provided with a second electrofusion element (22). The electrofusion elements (22,30) are connected by an integrated anvil-shaped connector (26) and connecting pin (28) such that both electrofusion elements (22,30) can be energised simultaneously using two electrical terminals (24,38), and the device can be manufactured with relative ease.
