Abstract

The utility model relates to a metal pipe strap which is composed of an upper pipe strap, a lower pipe strap, a sealing ring and coupling bolts. The top end of the upper pipe strap is provided with a flange with a screw bolt, and the upper and the lower pipe straps are combined to be appressed with a main pipeline and are connected by the screw bolt. After the main pipeline is perforated by a trepanning machine, a gate valve is connected to the flange at the upper end of the upper pipe strap. The utility model solves a problem that a branched pipeline is guided and connected under the condition of non stop of conveying mediums in the main pipeline, and replaces a three-way pipe in conventional construction. The utility model has characteristics that medium conveyance is not stopped, installation is convenient and operation is simple. The utility model is used for guiding and connecting branched pipes in water supplying industry, gas industry and petrochemical industry.

Description

Metal pipe strap

The utility model relates under a kind of situation that does not stop fed sheet of a media at pipe interior and draws the Metal pipe strap device that connects branch line.

At present, in town water supply, in coal gas and the petroleum chemical industry, use the line transportation medium, when needs were set up branch line, common way was at first to stop the medium transport of main pipe inside, cut off a section in the main pipe then, three-way pipe is installed therein, and drawing of branched pipe of enforcement connects, and the deficiency of its existence is, at first to stop the medium transport of main pipe, be not suitable for pipe first-aid in case of emergency; Secondly, inconvenient operation, installation process complexity.

Its purpose of the utility model just is to provide to draw under a kind of situation that does not stop fed sheet of a media at pipe interior and connects branch line, and simple, convenient a kind of Metal pipe strap device.

The technological scheme that realizes above-mentioned purpose and take is, a kind of Metal pipe strap, form by last pipe clamp, following pipe clamp, seal ring and attachment bolt, being shaped as " Ω " shape top, horizontal direction is the last pipe clamp of flange plate formation of strap bolt, its Vertical direction has through hole, via bottoms is equipped with seal ring, and following pipe clamp is shaped as , upper and lower pipe clamp combination is close to main pipe and is relied on Bolt Connection, is fixed on the main pipe axis in the hole of opening and main pipe intersect vertical axis on the last pipe clamp.

The utility model is described in further detail for the combination accompanying drawing below.

Fig. 1 is this apparatus structure plan view;

Fig. 2 is the side view of Fig. 1.

This device is made up of last pipe clamp 1, time pipe clamp 2, seal ring 3 and attachment bolt 4, and being shaped as " Ω " shape top, horizontal direction is the last pipe clamp 1 of flange plate formation of strap bolt 5, and its Vertical direction has through hole, and via bottoms is equipped with seal ring 3, and following pipe clamp 2 is shaped as

, upper and lower pipe clamp 1,2 combinations are close to main pipe 6 and are relied on bolt 4 to connect, are fixed on the main pipe 6, and the axis in the hole of opening and main pipe 6 intersect vertical axis on the last pipe clamp 1, and the diameter in the hole of opening equates with the required caliber that connects branch line that draws.Inferior card 2 has at least two to connect with last pipe clamp 1 according to the required pipe that connects branch line of drawing through size, and generally drawing the caliber that connects branch line is that two following pipe clamps 2 connect below 200mm, 200mm is above is three or more under pipe clamps 2 connections.At present pipe clamp 2 interior garden cambered surfaces are evenly equipped with two arcuation boss along perpendicular bisector together, and this boss is close to main pipe 6, becomes two supporting points of pipe clamp 2 down.

In the as installed process, at first upper and lower pipe clamp 1,2 usefulness bolts 4 are connected and fixed on main pipe 6, main pipe 6 is not stopping under the interior media conveying situation, must not disconnect main pipe 6, use size on main pipe 6 corresponding the leave through hole of pipe tapping machine along the hole of opening on the last pipe clamp 1, this hole size is draws the caliber size that connects branch line, then the standard gate valve is connected on the flange plate of pipe clamp 1 upper end, promptly having finished drawing of whole branch line connects, at any time stand-by, replaced the three-way pipe in the conventional construction.

Compared with prior art this device has the following advantages.

1) owing to being installed on the trunk line, this device is connected with the standard gate valve after the perforate, And use sealed tapping machine, trunk line delivered inside medium can not overflow, thereby does not need The interior media that stops main line being carried.

Only need to rely on bolt-connection be fixed in supervisor upper and lower pipe clamp during 2) owing to use Also perforate on the road, thereby do not need to disconnect trunk line, have easy for installation, simple to operate Characteristics.

3) because the boss supporting point of two symmetries is arranged on the cambered surface of garden in the pipe clamp down, thereby pipe clamp easy-rupturing not down, damage.

Claims

1, a kind of Metal pipe strap is made up of last pipe clamp 1, following pipe clamp 2, seal ring 3 and attachment bolt 4, it is characterized in that, being shaped as " Ω " shape top, horizontal direction is the last pipe clamp 1 of flange plate formation of strap bolt 5, its Vertical direction has through hole, and via bottoms is equipped with seal ring 3, and following pipe clamp 2 is shaped as

, upper and lower pipe clamp 1,2 combinations are close to main pipe 6 and are relied on bolt 4 to connect, and are fixed on the main pipe 6 axis in the hole of opening and main pipe 6 intersect vertical axis on the last pipe clamp 1.

2, Metal pipe strap according to claim 1 is characterized in that, the hole of opening directly equates with the required caliber that connects branch line that draws through size on the last pipe clamp 1.

3, Metal pipe strap according to claim 1 is characterized in that, the garden cambered surface is evenly equipped with two garden arcuation boss along perpendicular bisector in the following pipe clamp 2, and this boss is close to main pipe 6.
