Embodiment Construction

[0012] An open-loop half-arc sealing gasket, comprising two opposite semi-arc sealing rings 10, the half-arc sealing gasket also includes a sealing strip 20 for connecting the two sealing rings 10, the two ends of the sealing strip 20 are respectively connected to One of the same side ends of the two sealing rings 10, such as Figure 1-2 shown.

[0013] In order to specifically limit the above structure, the projection of the Huff joint gasket on the plane perpendicular to its installation direction is groove-shaped, and the plane perpendicular to its installation direction is as follows Figure 3-4 The plane shown is parallel to or coincident with the two sides of the half-section shell. In actual application, the half joint gasket is symmetrically installed in the prefabricated groove of the half joint shell along the central axis of the half joint shell. In other words, each half joint seal is in the shape of image 3 The prefabricated grooves of the half joint shell show...

Abstract

The invention belongs to the technical field of pipeline repair, particularly relates to an open-loop Hough section seal pad comprising two semi-arc-shaped seal rings which are arranged oppositely, and a seal strip which is used for connecting the seal rings; and both ends of the seal strip are respectively connected to one ends of the two seal rings which are on the same side. When the open-loop Hough section seal pad is used, not only can the installation stability, the high pressure resistance and the water hammer resistance of the whole seal pad be ensured, meanwhile because the number of the seal strip is reduced, the overall used amount of materials is effectively reduced, the production and manufacturing cost can be reduced, and the economic benefits of an enterprise are ensured.

Description

technical field [0001] The invention belongs to the technical field of pipeline emergency repair, and in particular relates to an open-loop half-joint gasket. Background technique [0002] The half joint is a device that seals and wraps the leakage or damage of the pipeline to achieve rapid repair. Its structure is simple, and it only needs two half joint shells installed opposite to each other and set on the joint surface of the half joint shell. It can be composed of two pieces of rubber pads, and it is easy to install at the same time. When in use, put the two shells together and tighten the nuts at the leaking place to complete the emergency repair of the pipeline; this device can not only save the time of water stoppage, but also reduce the cost of emergency repair , so it is widely used. The structures of the existing closed-loop half joint gaskets are distributed symmetrically about the central axis of the shell, such as Figure 7 As shown, it specifically includes a...
