Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of pipe fittings.
Background technique
On the pipeline of conveyance fluid, usually need out a branch support interface.Existing method is at the pipeline place that needs are opened the branch support interface pipeline to be blocked, and connects a three-way union then, and the branch support interface of three-way union is connected with lateral.Existing this method workload is big, and operation is trouble very.Under normal conditions, because original pipeline has installed and fixed and can't move, the operation easier that connects a three-way union after therefore pipeline being blocked is very big.Sometimes, can leakage phenomenon occur, influence the normal use of pipeline because of the connection imprecision of three-way union.
The method that the snap ring that adopts the inventor to provide connects with pipeline can connect lateral at random position at an easy rate.But when specific operation, the fluid in the pipeline need stop to carry, so that bore tap hole on pipeline.Like this, the normal transportation work of fluid in the pipeline will be had influence on.
Summary of the invention
The purpose of this utility model is at the problems referred to above, a kind of snap ring with cutting head is provided, when being applied to pipelines such as polymer by it, not only open the branch support interface at the random position of pipeline at an easy rate, and do not need the fluid in the pipeline to stop to carry, have characteristics such as fitting operation convenience, good seal performance.
The purpose of this utility model can realize by following technical proposal: the snap ring of this band cutting head comprises snap ring top and snap ring bottom, both all are the cross section is semicircular laminar body, both are fixed together by coupling mechanism and form a complete drum, fixing a branch tube at the outer surface on snap ring top, the endoporus of branch tube passes snap ring top, and be provided with a seal ring in the inner of branch tube, it is characterized in that, a cutting head is set in the endoporus of branch tube, cutting head links by screw thread and branch tube, the inner of cutting head has blade, is provided with the connecting tube that communicates with branch tube at the sidepiece of branch tube.
In the snap ring of above-mentioned band cutting head, be provided with capping in the outer end of branch tube, capping links by screw thread and branch tube.
In the snap ring of above-mentioned band cutting head, described coupling mechanism is that an end of snap ring top and snap ring bottom is hinged, and the other end links by bolt.Coupling mechanism also can adopt another kind of mode, and promptly the two ends of snap ring top and snap ring bottom all link by bolt.
By this dual mode snap ring top and snap ring bottom are fixed together.
When this snap ring is installed, be fastened on snap ring top and snap ring bottom on the pipeline that will connect after, snap ring top and snap ring bottom are fixed together.Can pass through rotary cutting head then, on pipeline, bore a tap hole.
In the snap ring of above-mentioned band cutting head, described connecting tube and branch tube are connected as a single entity.In use, connecting tube directly is connected on the branch line gets final product.
In the snap ring of above-mentioned band cutting head, there is a cylindrical body that communicates and be connected as a single entity with connecting tube the end of described connecting tube, cylindrical body axially and connecting tube axial vertical, cylindrical body is socketed on the branch tube, and the upper and lower in cylindrical body and branch tube contacting point all is provided with seal ring, has the through hole that communicates with the connecting tube endoporus on branch tube.In this structure,, prevent the joint leadkage of cylindrical body and branch tube by seal ring.Because cylindrical body is socketed on the branch tube, so connecting tube can be rotated around branch tube, connects with branch line in any direction.
The snap ring of this band cutting head is applied on the softer metallic conduit of plastic pipe or material usually.
The installation steps of the snap ring of this band cutting head are:
1, the duct size of opening the branch support interface is as required chosen the snap ring of corresponding specification, snap ring top and snap ring bottom are fastened and is fixed on the pipeline.
2, connecting tube is connected on the branch line.
3, rotary cutting head by blade perforate on pipeline of cutting head front end, and utilizes cutting head to block the pipeline inner fluid to leak.
4, the counter-rotating cutting head is return it, and makes maintenance sealing between cutting head outer end and branch tube or the capping.
Like this, the fluid in the pipeline will flow out from branch tube, and the through hole by the branch tube sidepiece flow on connecting tube and the branch line.
Adopt the snap ring of this band cutting head to open the branch support interface, on pipeline, not only do not need to block pipeline, and needn't make the fluid in the pipeline stop to carry, so its fitting operation is very convenient, work efficiency is high.In this snap ring, link by screw thread between each part, connect firmly.Owing to be provided with seal ring in the connection place, make snap ring with have the better seal performance after pipeline connects.
