Description
Technical field
The utility model relates to a kind of PE pipe connecting structure, and specifically, the utility model relates to the online electric smelting of a kind of PE pipeline and connects saddle type side-port nipple.
Background technique
PE pipe with the polythene material manufacturing has very high compressive strength and anti-corrosion capability, and easy to connect, reliable, and contemporary civilian water delivery, gas pipeline generally use the PE pipe.Be responsible in the pipe network along the line and supply water or air feed to the user through drawing arm; Usually adopt two kinds of technology to realize that arm is connected with the person in charge in the engineering; Most common technique is to confirm to preset threeway on the position the person in charge, and another kind is after being responsible for laying, to connect saddle type side-port nipple according to the newly-increased requirement of user through electric smelting.These two kinds of bypass arm interconnection techniques are all very ripe, can accomplish to be tightly connected as required.But; The former reserves threeway by specified position when be responsible for laying, the connection state of perhaps cutting off the water, stop the supple of gas or steam the person in charge under is because of water delivery, the gas pipeline of same pipe network relates to huge numbers of families; Do not allow anyone person in charge that arbitrarily stops, constitute newly-increased arm connection inconvenience thus.It is a kind of bypass tube of online connection that existing electric smelting connects saddle type side-port nipple; Need not be responsible for and cut off the water or stop the supple of gas or steam and just can realize that arm connects, existing technology is easy to connect, reliable, mobility strong; Instantaneity is good, influences other users on the same person in charge when avoiding the arm connection.However, in use still existence is not enough for existing technology, and for example on the arm mounting point, getting through the hole of being responsible for wall formation has overlap, and the stripping and slicing delocalization of cutting-out is prone to fall into interior being washed away by medium of the person in charge and causes downstream line to stop up.In addition, when getting through the person in charge, produce smear metal, smear metal is along with media flow in the pipe flow to downstream user, and smear metal is prone to cause the pipeline corollary equipment of downstream user malfunctioning.
The model utility content
The utility model is primarily aimed at the deficiency of existing technology; Propose a kind of rational in infrastructure, connect convenient, sealing is reliable; It is sliding to get through the hole marginal ray of being responsible on the wall, and the online electric smelting of PE pipeline that punching does not produce the stripping and slicing location indwelling of smear metal and cutting-out connects saddle type side-port nipple.
The utility model is realized technical goal through following technical proposals.
The online electric smelting of PE pipeline connects saddle type side-port nipple, and it comprises top cover, seal ring, punching cutter, body, heater band, bolt and pressing plate.Said body is three-way pipe member in length and breadth; The vertical tube inner chamber is a tapped hole; The punching cutter of down-bite jaw and vertical tube interior threaded hole screw fit constitute axially screw-in perforation structure, and vertical tube waist one side is provided with horizontal bypass tube, and the vertical tube bottom is provided with the semicircle saddle perpendicular with bypass tube; Saddle inwall ring vertical tube endoporus down is embedded with heater band, and the saddle dual-side is respectively equipped with the through hole of hasp hole and construction bolt.Its improvements are: said punching cutter is the cutter of cylindrical structure, and inner hole wall is provided with screw thread, is uniformly distributed with 3～6 one down on the outer shroud end face circumference along tilting cutting edge, and the lead angle λ that cutting edge oblique angle α equals the endoporus internal thread is 5 °～7 °; Said pressing plate is semicircle hollow out member; One end is the screens end; The other end is a connecting end; Platen width is more than or equal to the diameter of punching cutter, and the screens end is provided with hasp and cooperates formation INSERTTYPE quick fixation structure with hasp hole on the saddle, and connecting end is provided with screw and is installed in that bolt locks body on the saddle.Said seal ring is inlaid in aperture outer wall on top cover interior edge face and the body respectively, and top cover is tightened onto on the body aperture and forms axially and double sealing structure radially.
Further improve as the utility model, be provided with two hasps on the width direction at pressing plate screens end and cooperating with two hasp holes on the saddle, connecting end is provided with two bolts installing on pair tapped holes and the saddle and cooperates.
The utility model compared with prior art has following good effect:
1, the riser upper end of top cover and body adopts the double sealing structure, and sealing is reliable;
2, the cutting edge of punching cutter is for cutting sth. askew into structure, and the stripping and slicing periphery is revolved and is extruded into outside thread when being responsible for the wall punching, does not produce smear metal; Medium is not contaminated in being responsible in the work progress; The stripping and slicing of downcutting cooperates the location with the cutter inner hole thread that punches, and guarantees to be responsible for unimpeded, and downstream user is unaffected;
3, the saddle of pressing plate and body lower end adopts the hasp type insert structure, is convenient to quick-acting and quick-discharging, improves efficiency of construction.
