Abstract
The utility model relates to a heat preservation coaxial double-piped flange, which is suitable for producing heat preservation and material delivering pipelines in chemical industries. The utility model is composed of a concave flange disk, a convex flange disk and a sleeve barrel, wherein, ventilating holes are arranged on the flange and are installed on a heat preservation pipeline, so a bypass ventilating hole pipe arranged at the flange can be saved. High-temperature gas can be directly transported through the ventilating hole arranged on the flange, so the loss of vapor entropy power, the generation and the accumulation of condensed water, and generated failures can be reduced. The utility model has the advantages simple structure, convenient loading and unloading, and easy use.
Description
A kind of special flange that is applicable to the insulation carrier pipe of Chemical Manufacture.
Chemical Manufacture is failed the material insulation pipe at present, all adopt in the sleeve pipe outside carrier pipe, charge into high-temperature vapour, in the sealing of flange place outer sleeve, the by-pass pipe of burn-oning joins, steam flow is to unreasonable, the by-pass pipe formation condensed water of lowering the temperature easily, resistance strengthens, and loss steam entropy is difficult for realizing that condensation is hydrophobic, often dismounting is keeped in repair and influence production, and loading and unloading inconvenience and the difficulty that exists the length distance to carry.
The purpose of this utility model is: design a kind of cancellation by-pass pipe, improve flange configuration, utilize flange directly to ventilate, to overcome the above-mentioned problem that exists, And can reach the novel flange of easy installation and removal.
The purpose of this utility model is to realize like this, design a kind of insulation concentric double pipe flange, it is characterized in that: this flange is made up of concave, convex flange plate and sleeve, material of carrying and insulation gas can pass through flange simultaneously, 8 vents are arranged on the relative position of concavo-convex flange plate, are lined with sealing gasket in the middle of the concavo-convex flange plate, install fastening after, welded sleeve on outer tube and the flange plate can make pore and outer tube on the flange form path.
Below in conjunction with accompanying drawing embodiment is described:
Fig. 1 is a boss flange dish structure view: wherein Figure 1A is a sectional view, and Figure 1B is a plan view, and screw hole (2), vent (3) and material hole (4) are arranged on boss flange dish (1).
Fig. 2 is recessed flange plate structure view: wherein Fig. 2 A is a sectional view, and Fig. 2 B is a plan view, and screw hole (2) is arranged on recessed flange plate (1), vent (3) and material hole (4).
Fig. 3 is the sleeve structure sectional view: on sleeve (1), have weep hole (2) and outside pore (3).
Fig. 4 is embodiment's erection drawing: be made up of pipe (6) in boss flange dish (1), recessed flange plate (2), sealing gasket (3), sleeve (4), outer sleeve (5) and the material.
Material is carried by interior pipe, and high-temperature vapour flows through by outer sleeve and flange pore, reaches the effect to interior pipe material insulation.
