Abstract
The invention discloses a pressure flange which comprises a pipeline and a flange plate matched with and connected to the outer periphery of the pipeline. The flange is characterized in that the inner periphery of the flange plate is provided with an annular groove. The pressure flange has the advantages of safety, long service life and good sealing performance and is suitable for being used under high working pressure.
Description
Technical field:
The present invention relates to the Pipe jointing part field, be specifically related to a kind of pressure flange, be applicable to faggot kitchen range UTILIZATION OF VESIDUAL HEAT IN.
Background technique:
Commercially available FRP flange adopts flat pattern seal face structure more at present, bonding firm degree between the flange of this kind structure and flange are taken over is low, and prestressing weak effect, cause in pipeline, carry material pressure when higher, gasket seal easily is extruded clamping piece, sealing effect is poor, therefore only is applicable to the occasion use that pressure is lower.Chinese patent, the patent No.: 02254397.X discloses a kind of pressure flange, comprises short tube, is coupled to the flange plate of short tube periphery; Described short tube periphery bottom offers annular groove.This pressure flange is owing to offer annular groove in the pipeline periphery, and conduit hardness descends, and under the high pressure, pipeline ruptures easily, and the dielectric leakage phenomenon takes place.
Summary of the invention:
For solving the deficiencies in the prior art, the invention provides the pressure flange of a kind of safety, long service life, good seal performance.
The present invention is achieved in that pressure flange, comprises pipeline, is coupled to the flange plate of pipeline periphery, it is characterized in that: week offers annular groove in the described flange plate.
The working surface surface of described flange plate is that the center offers at least two annular grooves with the pipeline.
The annular groove on the working surface surface of described flange plate is that the center is the concentric circle distribution with the pipeline.
The formed plane of annular groove in week is parallel to each other in the described flange plate.
The formed plane of annular groove in week is parallel to each other and is spacedly distributed in the described flange plate.
The vertical sectional shape of the annular groove on the working surface surface of the annular groove in week, flange plate is isosceles triangle in the described flange plate.
The vertical sectional shape semicircular in shape of the annular groove on the working surface surface of the annular groove in week, flange plate in the described flange plate.
The vertical sectional shape of the annular groove on the working surface surface of the annular groove in week, flange plate is isosceles triangle in the described flange plate.
The vertical sectional shape semicircular in shape of the annular groove on the working surface surface of the annular groove in week, flange plate in the described flange plate.
Pressure flange of the present invention is because working surface surface all in flange plate, flange plate offers annular groove, make between pipeline periphery and the flange plate, the working surface surface of flange plate between bonding firm degree increase greatly, thereby the overall sealing performance of flange is improved, it can be adapted under the high workload pressure use.The advantage of pressure flange of the present invention is the use down of safety, long service life, good seal performance, adaptation high workload pressure.
Description of drawings:
Accompanying drawing 1 is the structural representation of the embodiment of the invention.
Accompanying drawing 2 is for being partial enlarged drawing between the pipeline periphery of Fig. 1 and the flange plate.
Label among Fig. 1, Fig. 2 is: 1, pipeline; 2, flange plate; 3, annular groove; 4, annular groove.
Embodiment:
Below in conjunction with drawings and Examples, the present invention is described in further detail, but do not constitute any limitation of the invention:
According to Fig. 1,2 as can be known, pressure flange of the present invention comprises pipeline 1, is coupled to the flange plate 2 of pipeline 1 periphery, offers annular grooves 3 week in the described flange plate 2; The working surface surface of described flange plate 2 is that the center offers at least two annular grooves 4 with pipeline 1; Described annular groove 4 is that the center is the concentric circle distribution with pipeline 1; Described annular groove 3 formed planes are parallel to each other and are spacedly distributed; The vertical sectional shape of described annular groove 3,4 is isosceles triangle.Between pipeline periphery and the flange plate, the working surface surface of flange plate between adopt to be adhesively fixed and be connected.
