Description

Double-blade internal threaded pipe

[ technical field ] A method for producing a semiconductor device

The utility model relates to a technical field of water-cooling wall, in particular to technical field of bilobalt internal thread pipe.

[ background of the invention ]

The water wall is the main heated part of the boiler, it is made up of vertical steel tube, it distributes and surrounds the boiler furnace, its inside is the flowing water, the outside accepts the heat of the flame of the boiler furnace, the present steel tube welds together with the bare pipe through the flat steel to make up the tube panel, form two welding seams between the tube, the welding time is long, the inefficiency, and the intraductal bare pipe generally, form the vapor film easily, influence the cooling effect, therefore it is necessary to propose a kind of double-blade internal thread tube.

[ Utility model ] content

An object of the utility model is to overcome above-mentioned prior art not enough, provide a bilobed piece internal thread pipe, it aims at solving among the prior art between the pipe and the pipe welding will form two welding seams, and is inefficient, and intraductal for the fluorescent lamp, the not good technical problem of cooling effect.

In order to achieve the purpose, the utility model provides a double-blade internal thread pipe, including pipe, blade, internal thread, the pipe on be equipped with two blades, two blades install respectively in the left and right sides of pipe, the pipe on be equipped with the internal thread.

Preferably, a plurality of connecting grooves are formed in the pipe, a plurality of water storage holes are formed in the pipe, the water storage holes are uniformly distributed in the pipe, and the number of the connecting grooves is at least one.

Preferably, the two blades are bilaterally symmetrical about the central axis of the pipe, each blade comprises a blade body, a carrying groove and a wave protrusion, the carrying groove is arranged at the bottom of the blade body, and the wave protrusion is arranged above the carrying groove.

Preferably, a plurality of expansion seams are arranged on the internal thread, and the expansion seams are vertically connected with the internal thread.

The utility model has the advantages that: compared with the prior art, the utility model provides a pair of two-blade internal thread pipe, it is rational in infrastructure, be equipped with the internal thread in the pipe, strengthened near fluidic disturbance of pipe internal face, the reinforcing mobility improves cooling efficiency, and lug connection can reduce the welding seam between the blade, shortens the welding time, increases production efficiency.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
