    摘要： A seal clamp, such as for gas lines, includes a handle assembly having a handle, a transfer or drive assembly cooperable with the handle, and a clamping assembly including first and second claws or clamps and a seal member. The first and second claws or clamps are cooperable with the transfer assembly. The seal member is structured to seal a puncture in a gas line. Responsive to movement of the handle, the first and second claws or clamps move from an OPEN position to a CLOSED position, such as to engage a pipe and create a clamping force which forces the seal member into engagement with the pipe, such as a puncture, to seal the pipe.

    摘要： A leak clamp assembly for repairing a leak in a spigot and socket joint in a gas pipe includes a split sealing ring of resilient material which is placed around the spigot and against the outer face of the socket and a split rigid backing-up ring which is also placed around the spigot on the side of the sealing ring remote from the socket and a series of clamps which act between the backing-up ring and the back face of the socket. The backing-up ring comprises at least two arcuate sections containing a bolt hole at each end, the sections being connected end to end to form the ring and overlapping at their junctions so that the corresponding holes are at least partly in register with each other. The clamps comprise bolts for passing through the pairs of overlapping holes and designed to engage behind the socket preferably with an anchor ring which is assembled around the pipe behind the socket. The bolts comprise a conventional shank for cooperation with a nut and a head which tapers to the shank, the arrangement being such that the backing-up ring section can be arranged with the bolt holes overlapping to a minimum degree around the shanks of the bolts to provide the backing-up ring with a maximum size, but on tightening the nuts on the bolts, the tapered heads are drawn into the overlapping holes thus increasing the extent of the overlap and drawing the backing-up ring sections further together until the backing-up ring tightly engages the sealing ring and clamps it around the spigot and against the face of the socket of the spigot and socket joint.

    摘要翻译： 用于修复气体管道中的插口和插座接头中的泄漏的泄漏夹具组件包括弹性材料的分离密封环，其被布置在插口周围并抵靠插座的外表面，并且分离的刚性支撑环 也放置在远离插座的密封环一侧的插口周围，以及作用在支撑环和插座背面之间的一系列夹具。 所述支撑环包括至少两个在每个端部处包含螺栓孔的弧形部分，所述部分端对端连接以形成所述环并且在其连接处重叠，使得相应的孔至少部分地彼此对准。 夹具包括用于穿过成对的重叠孔的螺栓，并被设计成在插座后方优选地与在套管后面的管道组装的锚环相配合。 螺栓包括用于与螺母和头部配合的常规柄，所述螺母和头部朝向所述柄部渐缩，所述布置使得所述支撑环部分可布置成使得所述螺栓孔围绕所述螺栓的柄部以最小程度重叠， 提供最大尺寸的支撑环，但是在拧紧螺栓上的螺母时，锥形头被拉入重叠孔，从而增加重叠的程度并进一步将支撑环部分拉到一起， 紧固环紧密地接合密封环并将其夹在套管周围并抵靠插口和插座接头的插座的表面。
