Abstract

The utility model relates to a reduced hoop tee used for stopping leak of leakage pipe lines and branch pipe lines arranged on and connected with the main pipe lines. The utility model comprises an upper and a lower hoops, a seal ring and a fastener, wherein the upper hoop is provided with a reduced flange interface, a location assembly is arranged on the circumferences of the upper and the lower hoops to fix the position relative to the main pipe line. The utility model can stop and mend water leakage of hydraulic pipelines, more importantly, the utility model can be used to install and connect branch pipe lines on the main pipes under the circumstance of without shutting water and has the advantages of being fast and convenient to operate.

Description

The threeway of reducing hoop formula

Technical field the utility model is water (liquid) pipeline attaching by-pass line and repairs the device of leak stopping that it is a kind of reducing hoop formula threeway of pipeline leakage plugging under water or attaching by-pass line.

Background technique is wanted the attaching by-pass line before this in water delivery (liquid) pipeline, must cut off the water and install, the sector also not under the condition of not cutting off the water on main pipe the isolated plant of attaching by-pass line.

Summary of the invention is in order to carry out the attaching by-pass line or to repair the plugging road leaking not cutting off the water, and the utility model has aimed to provide the threeway of a kind of reducing hoop formula.

The technical solution of the utility model that realizes above-mentioned purpose and design mainly includes down hoop, goes up hoop, seal ring and fastening piece, the internal surface of upper and lower hoop has o-ring groove along week, the adhering and sealing circle, upper and lower hoop is connected by fastening piece, it is cylindrical that inner chamber becomes, at last hoop the reducing flange interface is arranged, on the circumference of last hoop, following hoop, be equipped with dowelling assembly, this dowelling assembly has holding down bolt, nut, location sealing seat and O RunddichtringO, holding down bolt connects to be gone up hoop and binds round on the circumference assembling O RunddichtringO in the sealing seat of location down.

The utility model can not only carry out mending-leakage water pipe leak stopping water, and its hoop design of going up has the reducing flange interface, specialize on the pipeline dress valve and connect by-pass line, therefore, it can be used for the mending-leakage water pipe and leak, again can be under the situation that pipeline is not cut off the water the attaching by-pass line, can reduce labor intensity the advantage when having saving of labor, joint.

Drawing explanatory drawing 1 is a topology view.

Fig. 2 is that Figure 1A is to view.

1-down hoop, 2-hoop gone up, 3-seal ring, 4-sealed groove, 5-O RunddichtringO, 6-square head bolt, 7-hexagon nut, 8-location sealing seat, 9-holding down bolt, 10-reducing flange interface.

Embodiment with reference to the accompanying drawings 1 and Fig. 2 details are as follows to technology contents of the present utility model: the following hoop 1 and the last hoop 2 of this reducing hoop formula threeway are a watt shape, and internal surface is along being processed with o-ring groove 4 week, and seal ring 3 interlockings are in o-ring groove 4.Upper and lower hoop 2 and 1 is fastenedly connected by square head bolt 6 and hexagon nut, upper and lower hoop 2 and 1 and seal ring 3 constitute the reducing hoop formula threeway of a sealing, last hoop 2 have with on the hoop the 2 reducing flange interfaces 10 that are cast as one, the bore that the diameter of this reducing flange interface 10 can designed size differs is for the interface of processing by-pass line not of uniform size.Device has dowelling assembly on upper and lower hoop 2 and 1, the holding down bolt 9 of this dowelling assembly is uniform to be threaded on the excircle of upper and lower hoop 2 and 1, generally be equipped with 3 holding down bolts 9, equidistantly be arranged on the circumference with alternate 270 °, holding down bolt 9 activities are equipped with hexagon nut 7 and have location sealing seat 8, are equipped with O RunddichtringO 5 in the sealing seat 8 of location.In sealed groove 4, be bonded with seal ring 3 on hoop 2 and down hoop 1 be socketed in the pipe place that leaks and be fastened and connected by fastening piece square head bolt 6 and hexagon nut, consult Fig. 1 and Fig. 2.

Be used for the leak stopping water pipe, just install additional on reducing flange mouth interface 10 and connect blind flange, the periphery pad in the middle of reducing flange interface 10 and the blind flange connects seal ring, is fastened and connected with the fastening piece square headed screw.Location sealing seat 8 compresses O RunddichtringO 5 by hexagon nut 7, implements to repair leaking in the stifled water transport pipeline.

This reducing hoop formula threeway mainly is to be used in the main pipe attaching by-pass line is installed, during installation, three holding down bolts 9 are tightened roof pressure on main pipe on it, fix the position of these reducing hoop formula three roads with main pipe, and on last hoop 2 and following hoop 1 circumference, compress location sealing seat 8 and O RunddichtringO 5 with hexagon nut 7, the water that prevents main pipe spills, load onto valve at reducing flange by mouth 10 places, load onto drilling device from the outlet port of valve, open valve then and carry out bore operation, finish boring, withdraw from drill bit, throttle down is laid down drill bit, just can finish the attaching by-pass line.

Claims

1, a kind of reducing hoop formula threeway, it includes down hoop, goes up hoop, seal ring and fastening piece, seal ring is bonded in down, binds round down internal surface along in the o-ring groove in week, upper and lower hoop is connected by fastening piece, it is characterized in that hoop (2) has reducing flange interface (10), device has dowelling assembly on the circumference of upper and lower hoop (2) (1).

2, reducing hoop formula according to claim 1 threeway, it is characterized in that dowelling assembly has holding down bolt (9), hexagon nut (7), location sealing seat (8) and O RunddichtringO (5), uniform hoop (2) and the following hoop (1) of being threaded in of holding down bolt (9), is equipped with O RunddichtringO (5) in the location sealing seat (8).
