Abstract
The utility model discloses a reinforced fast hafu joint, which comprises a pair of arc-shaped housings formed by that a plurality of screw bolts are connected into a whole, and rubber sealing gaskets arranged on two end openings of an inner liner. The reinforced fast hafu joint is characterized in that a positioning block is arranged between the arc-shaped housings and a positioning hole for placing the screw bolts, and reinforced ribs are arranged on a casing opposite to grooves arranged on the two end openings of the arc-shaped housings. The hafu joint with the structure can automatically fix the upper ends of the screw bolts, and the screw bolts can not rotate when screw caps are screwed tightly. Thereby, the first-aid repair time can be saved, the labor intensity can be reduced and the waste of the resources of water and coal gas can be reduced. The hafu joint can bear large pressure, and rupture can not occur. The utility model is ideal equipment for the first-aid repair of pipelines.
Description
Technical field
The utility model relates to a kind of pipeline breaking repairing equipment, specifically a kind of Hough joint.
Background technique
Existing Hough joint comprises rubber gasket two parts of a pair of arc shell and inner bag two-port groove; when water supply pipe or gas pipe line break when rushing to repair; the pipeline that a pair of arc shell will be broken clamps bolt and the nut of tightening respectively again on the housing; but bolt usually can rotate when tightening nuts; so fix with wrench on the bolt top always at present; the nut end again with wrench fastening just can tighten fixing; waste time and energy; labor intensity is big; the repairing time is long, has also caused the waste of water or coal gas resource.And it is thinner that present Hough saves two port recess places, still can break when pressure is big.
The model utility content
The purpose of this utility model is to overcome above shortcoming, provides a kind of and can save the repairing time, reduces labor intensity, can reduce the quick Hough joint of the waste of water or coal gas resource.The purpose of this utility model also is to provide a kind of reinforced Hough joint that can bear bigger pressure.
The utility model comprises a pair of by a few joint bolts arc shell that fuses and the rubber gasket that is positioned at inner bag two-port position, it is characterized in that at arc shell and place between the positioning hole of bolt being provided with positioning block, the two-port groove of arc shell over against shell on be provided with stiffening rib.
Positioning block length equals the length of positioning hole.
The Hough joint of this structure is owing to be provided with positioning block between the positioning hole of housing and placement bolt, automatically on the fixing bolt, bolt can not rotate when tightening nuts, thereby can save the repairing time, reduce labor intensity, can reduce the waste of water or coal gas resource; And the two-port groove of arc shell over against shell on be provided with stiffening rib.Thereby having improved intensity greatly, made the Hough joint can bear bigger pressure, can not break, is the ideal equipment of pipe first-aid.
