Abstract
The invention discloses a vacuum thermal insulating pipeline and manufacture and application thereof, being characterized in that a double-layer pipeline is formed by seal-connecting pipeline components such as a double-layer pipe, a double-layer swan neck, a double-layer three-way pipe, a double-layer four-way pipe and the like by a double-layer pipe joint; and isolation clamping rings are arranged with a certain distance between an inner-layer pipeline and an outer-layer pipeline so as to support and isolate the inner-layer pipeline from the outer-layer pipeline, and the air in the double-layer pipeline is extracted. A layer or a plurality of layers of heat-reflective film/films is/are wrapped on the outer wall of the inner-layer pipeline so as to prevent radiation heat transfer. By using the vacuum thermal insulating pipeline, cold deep seawater is introduced into various buildings and factories to be used as a cold source.
Description
Technical field
Involved in the present invention is a kind of vacuum thermal insulating pipeline.
Background technique
Pipeline heat insulation is the essential condition that realizes many product technologies, also is the importance of saving energy and reduce the cost.But traditional pipeline heat insulation is to adopt the method that thermal insulating material is set outside pipeline to realize.The shortcoming of this method is that heat insulation effect is poor, and thermal insulating material requires frequent maintenance and replacement.
Summary of the invention
For addressing the above problem, the invention provides a kind of vacuum thermal insulating pipeline and manufacturing thereof and application.Its technological scheme is:
1, is tightly connected with pipeline components such as bimetallic tube joint and bimetallic tube, double-deck swan neck, double-deck three-way pipe, double-deck four-way pipes, forms Double layer pipeline; Between the internal and external layer pipeline, keeping at a certain distance away is provided with the isolation snap ring, internal layer pipeline and the support of outer pipeline is kept apart, and the air between the Double layer pipeline is taken out, and forms the pipeline with vacuum heat-insulating layer.
2, each jointing can seal or welded seal with the elastic seal ring that compresses.
3, the bimetallic tube joint can be made of one structure, and the inside and outside layer pipe joint in the bimetallic tube joint also can be made separately and be used.
4, pipeline components such as double-deck swan neck, double-deck three-way pipe, double-deck four-way pipe can be made of one structure, and are connected use with the bimetallic tube joint.
5, one or more layers thermal reflecting coating of parcel on internal layer pipeline outer wall is to prevent radiative heat transfer.
6, with this vacuum thermal insulating pipeline deep layer Mare Frigoris water is introduced in various buildings and the factory and used as low-temperature receiver.
7, with anticorrosion valve and the heat exchanger made with the anticorrosion material of plastics, pottery, glass or the like, or in the set up defences metallic recuperator etc. of rotten film, form seawater refrigeration or air-conditioning system with above-mentioned vacuum thermal insulating pipeline.
This vacuum thermal insulating pipeline has high insulating effect, and cost is low, remarkable advantages such as long service life are installed simply in manufacturing.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the three-dimensional outline drawing of this vacuum thermal insulating pipeline.
Fig. 2 is the transverse center sectional elevation of Fig. 1.
Fig. 3 is the D structure figure that isolates snap ring.
1. external pipe among the figure; 1a. inner tube 2. is made of one structure bimetallic tube joint; 3. double-deck three-way pipe; 4. isolation snap ring; 5. seal ring.
Embodiment
Among Fig. 2, when pipeline is installed, inner tube (1a) and inner tube joint can be connected earlier sealing and isolation snap ring (4) is installed, again external pipe (1) is connected sealing with the external pipe joint; When pipeline components such as double-deck swan neck, double-deck three-way pipe, double-deck four-way pipe are connected with the bimetallic tube joint, can earlier inner tube be connected sealing with the inner tube joint, again external pipe be connected sealing with the external pipe joint.
The double-deck three-way pipe that only drawn among the figure, double-deck swan neck is similar to its structural principle with double-deck four-way pipe etc.
Vacuum pumping port can be arranged on the outer wall of pipeline components such as bimetallic tube, bimetallic tube joint, double-deck swan neck, double-deck three-way pipe, double-deck four-way pipe.
