The present invention has the advantages of simple structure, convenient operation, the realization of the line assembly and no leakage of a pressed pipeline, no pollution and safe construction; compared with the known technique, the present invention can save lots of cost.
Description
The invention belongs to pipe fittings, a kind of more precisely device that is used for realizing on the pipeline with pressure connection of band pressure.
Band pressure pipe road---gas conveying tube road for example when needs pick out bye-pass in main line, normally utilizes valve that the pipeline of a certain area segments is blocked, and the coal gas emptying (burning usually) in will this section, implements the connection of bye-pass then.This method not only causes the manpower and materials waste, and certain danger is arranged.In the known technology also the someone adopt following method: have the pipeline welding of valve the desired area of main line (this position has formed corresponding thin-walled after pretreatment) with one section, relief valve behind the door, use the drill bit opening, extract drill bit then rapidly out, throttle down is implemented the welding to bye-pass at last.This method exists waste, particularly hidden danger equally.
The objective of the invention is: overcome the shortcoming of known technology, a kind of safety is provided, link is with the convenient of pressure pipe road to connect with realization reliably.
Pipe pressurized connector provided by the present invention is characterized in that: have one by the main pipe interface, the three-way pipe that bypass tube and process duct are formed is being provided with the opening cutter that has seal arrangement in process duct, on the top of opening cutter the cutter hub positioning device is arranged.
For easy to process, reduce cost, above-mentioned opening cutter can be selected the split structure, promptly is made up of with connecting firmly at the cutter head of knife bar lower end knife bar.
Knife bar can be made into the reducing axle, and the knife bar body of rod at its major diameter place is provided with at least one circular groove, " O " the type rubber ring that places the seal arrangement of this groove to select for use.
Consider the stability of opening cutter work, can connect firmly a center bit in the center of cutter hub lower end surface.
For guaranteeing to finish cutting the back cutter hub promote and fix the cutter hub positioning device that is provided with at high level, its preferred version is included in the pair of parallel locating slot, corresponding with this locating slot on knife bar top, the positioning screw hole that is provided with on process duct and be fitted in cutter hub positioning screwn in the positioning screw hole.
In order to guarantee that cutter hub realizes moving down, up and rotation the present invention the top of knife bar have one be used for outside the screw that joins of power.
In order further to guarantee the sealing of process duct, the present invention is provided with a flange plate on the top of process duct, and is equipped with it, and a blind differential is arranged at the top of process duct.Between flange plate and the blind differential Sealing is being set.
Main line interface of the present invention can be chosen in interface end an arc plate that matches with the main pipe outer wall.With welding manner arc plate is connected firmly on the body of main line.
The present invention also can be provided with a pair of lug on above-mentioned arc plate, and cooperates with it with a press table that has lug, at the cambered surface place of arc plate seal arrangement is arranged.
Introduce embodiment of the present invention below in conjunction with Figure of description:
Figure of description 1 is a structural representation of the present invention;
In the accompanying drawings, 1---the main line interface, 2---drill bit, 3---cutter head, 4---bolt, 5---knife bar, 6---seal arrangement, 7---flange plate, 8---positioning screwn, 9---blind differential, 10---bolt assembly, 11---Sealing, 12---process duct, 13---locating slot, 14---bypass tube, 15---lug, 16---seal arrangement, 17---press table, 18---screw.
As shown in the figure, main body of the present invention be one by main line interface 1, the three-way pipe that process duct 12 and bypass tube 14 formed, this three-way pipe can select for use materials such as cast steel, spheroidal graphite cast iron to make.Wherein, main line interface 1 can be made into that arc is tabular simply, and determines the cambered surface of arc plate according to the circular arc of main pipe tube wall.This structure is connecting firmly with airtight with Type of Welding realization and main line body in use.The present invention also can be provided with lug 15 to the both sides extension and in its both sides with above-mentioned arc plate.Cooperate with the arc plate that has lug 15, a press table 17 is arranged.Groove around the upper shed of main line body should be set on arc plate this moment, and embed Sealing 16.Certainly also can adopt known other sealing means such as rubber plate sealing.
The end of bypass tube 14 is established flange plate and is connected with pipeline and get final product.Process duct 12 can be made into the reducing body.The cutter hub that cooperates with process duct 12 is formed by knife bar 5 with through the cutter head 3 that bolt 4 connects firmly with it.The bottom surface of cutter head 3 (end) is one group of equally distributed cutter tooth, and contingent vibrations when considering cutter head cutting body also can connect firmly a drill bit 2 at the bottom center place of cutter hub.The blade branch (cutting part) that has of this drill bit 2 should be shorter, and the effect of centralized positioning can play in the drilling rod portion of drill bit 2.
Knife bar 5 is made the reducing axis body, and the major diameter structure on its top plays the sealing double action of knife bar guiding and process duct 12.Process at least one circular groove at this position, with its embedding " O " shape rubber ring closing process pipe 12 wherein.The both sides on knife bar 5 tops process a pair of locating slot 13, and locating slot 13 cooperates with positioning screwn 8 on being spun on process duct 12 tube walls realizes cutter hub fixing on process duct top, also can help the unit head of rig to withdraw from from the screw 18 at knife bar 5 tops.For making process duct 12 tops airtight more reliable, flange plate 7 is arranged at process duct of the present invention 12 tops, at blind flange 9 under the effect of bolt assembly 10 Sealing 11 is pressed against on the flange plate 7.
During use, main line interface 1 of the present invention is positioned at main line body fixed position really, then bypass tube 14 is connected with arranging the by-pass line that installs with welding or the solid mode of bolt connection.Rig connected firmly (in structure shown in Figure 1, removing blind differential 9, cooperating with flange plate 7 with bolt assembly 10 rig is fixed) on the process duct 12, the line shaft of rig is screwed in screw 18.Can implement cutting behind the back-out positioning screwn 8 to the main line body.After cutting finished, the body plate of cutting off fell in the main pipe, and mention cutter hub and be locked in process duct 12 upper ends this moment, laid down rig (the secondary sealing being carried out on process duct 12 tops with blind differential 9 and Sealing 11) and got final product.In above-mentioned work progress, coal gas is not revealed at all.
The present invention is simple in structure, behaviour does conveniently, realized that the road doubling of band pressure pipe do not have leakage, pollution-free, safe construction.Compare with known technology and can save the writing spending.
