Abstract
The utility model belongs to the technical field of pipeline emergency repair, and particularly relates to an open-loop half joint sealing gasket. The open-loop half joint sealing gasket comprises two semi-arc-shaped seal rings which are arranged oppositely, and sealing strips which are used for connecting the seal rings; and both ends of the sealing strip are respectively connected to one ends of the two seal rings, which are on the same side. When the open-loop half joint sealing gasket is used, through the sealing strips at three sides, the installation stability, the high pressure resistance and the water hammer resistance of the whole seal pad can be ensured, meanwhile because the number of the sealing strip is reduced, the materials of the whole open-loop half joint sealing gasket is effectively reduced, the production and manufacturing cost can be reduced, and the economic benefits of an enterprise are met.
Description
Technical field
The utility model belongs to the pipe first-aid technical field, is specifically related to a kind of open loop type sealing gaskets of Hafu joint.
Background technique
The Hough joint is that the seepage of pipeline or breakage spot are carried out sealed envelope to realize the device of repairing rapidly; It is simple in structure; Only need the Hough joint housing of two opposed installations can form with two rubber pads that are arranged at Hough joint housing faying surface place; Simultaneously easy for installation, during use two housings can be accomplished the repairing to pipeline to being combined in the place's of leaking fastening nut; Both can save the time of cutting off the water with this device, can reduce emergency repair cost again, therefore use very extensive.The structure of existing closed loop sealing gaskets of Hafu joint all is the medial axis symmetrical distribution about housing; As shown in Figure 7; The concrete half arc seal ring A that is arranged on its both sides that all comprises; Simultaneously between its seal ring end, be provided with connection Stamping Steel Ribbon B each other, tandem array finally constitutes the closed loop structure between above-mentioned each parts; The both sides inlay card that deviates from mutually that relies on two sealing gaskets when mounted is in the prefabricated fixed groove of Hough joint housing, and the side is then opposed at its place, relative both sides fits together, thereby finally relies on its both extrusion-deformation to improve its sealability.Yet, since above-mentioned closed loop structure, the raw material input amount of the every secondary sealing gasket of lifting that often will be passive, thus improved its fabricating cost greatly, bring very big puzzlement to the staff.
Summary of the invention
The purpose of the utility model provides a kind of open loop type sealing gaskets of Hafu joint, can be in the simplification property of guaranteeing to guarantee under the prerequisite of its high sealing performance its structure, and its production and fabricating cost are low.
For realizing above-mentioned purpose; The utility model has adopted following technological scheme: a kind of open loop type sealing gaskets of Hafu joint; Comprise the two half arc seal rings that are oppositely arranged; Sealing gaskets of Hafu joint also comprises the Stamping Steel Ribbon that is used to connect two seal rings, and the Stamping Steel Ribbon two ends are connected to wherein together on the side end of two seal rings.
The beneficial effect of the utility model is: after adopting said structure; During practical application; Sealing gaskets of Hafu joint is its housing pregroove marks place that is installed on along the medial axis symmetry of Hough joint housing, relies on the Stamping Steel Ribbon that is positioned at a certain sealing gasket one side place to save case side along cooperating with the Hough of this side during work respectively, can realize the seal action for this side direction of pipeline; In like manner; The then corresponding applying of the opposite side Stamping Steel Ribbon of its another sealing gasket is pressed in the Hough joint case side of opposite side along the place, to realize the sealing state of its body side, simultaneously; Its then corresponding supporting of corresponding seal ring that is positioned at Hough joint housing cambered surface place is closed the corresponding tube wall of treating the leak stopping pipeline, finally realizes its seal action fully; During use; Not only only rely on three banding bar structures, just can guarantee installation steadiness, barotolerance and the anti-water hammer property of its integral sealing pad, simultaneously; Owing to reduced its Stamping Steel Ribbon number; Also effectively reduce its whole materials amount, help reducing it and manufacture cost, guaranteed economic benefit of enterprises.

Embodiment
A kind of open loop type sealing gaskets of Hafu joint; Comprise the two half arc seal rings 10 that are oppositely arranged; Sealing gaskets of Hafu joint also comprises the Stamping Steel Ribbon 20 that is used to connect two seal rings 10, and Stamping Steel Ribbon 20 two ends are connected to wherein together on the side end, shown in Fig. 1-2 of two seal rings 10.
Be the concrete said structure that limits; The projection of preset here sealing gaskets of Hafu joint on the plane of vertical its installation direction is flute profile; And the vertical plane of its installation direction, be shown in Fig. 3-4 with Hough joint housing both sides along the plane that constitutes plane parallel or overlap.During practical application; Sealing gaskets of Hafu joint is its housing pregroove marks place that is installed on along the medial axis symmetry of Hough joint housing; In other words; Its each sealing gaskets of Hafu joint all be with Hough as shown in Figure 3 joint housing pregroove marks place mated condition inlay card in it, after installing, the Stamping Steel Ribbon 20 on two sealing gaskets of Hafu joint places its place, both sides, housing medial axis respectively simultaneously.Side that does not cooperate with the Stamping Steel Ribbon 20 of sealing gasket edge with Hough joint housing is exposed along a for it; The side edge that cooperates with Hough joint Stamping Steel Ribbon 20 housing and sealing gasket is its installation side b; With reference to shown in Figure 6; Rely on the Stamping Steel Ribbon 20 that is positioned at a certain sealing gasket installation side b place to expose during work respectively and cooperate, can realize seal action for this side direction of pipeline along a with the Hough joint housing of this side; In like manner, to be pressed in the Hough joint housing of opposite side exposed along a place, to realize the sealing state of its body side for 20 corresponding applyings of the opposite side Stamping Steel Ribbon of its another sealing gasket.Its 10 correspondences of corresponding seal ring that are positioned at Hough joint housing cambered surface place are supported and are closed the corresponding tube wall of treating the leak stopping pipeline, finally realize its seal action fully.In addition, the free end setting height(from bottom) that highly is higher than seal ring 10 after connecting ends on the seal ring 10 and Stamping Steel Ribbon 20 joints are installed; Height after the installation of its each end is seal ring as shown in Figure 5 10 two ends along height here, the complementation that is fitted to each other through two each end of sealing gasket during assembling, thus realize its firm sealing purpose; Because each fitted seal place of said structure still is the chimeric sealing configuration between sealing strip and housing; Not only only rely on three banding bar structures just can guarantee installation steadiness, barotolerance and the anti-water hammer property of its integral sealing pad; Again owing to reduced its Stamping Steel Ribbon number; Thereby effectively reduce its whole materials amount, help reducing it and manufacture cost, guaranteed economic benefit of enterprises.
