Abstract
The utility model relates to a clamping type direct connection flange which belongs to a pipeline connector and is provided with two opposite flange discs; connection holes are arranged on the flange discs; the utility model is characterized in that a clamping ring suitable for connecting a pipe is arranged; a clamping ring cavity corresponding to the clamping ring is arranged on the flange disc; a clamping pinhole is arranged on the clamping ring; a clamping pin is arranged in the clamping pinhole; the length of the clamping pin is larger than the thickness of the clamping ring; the outer end of the clamping pin is contacted with the inner wall of the clamping ring cavity; and the inner wall of the clamping ring cavity is in a wedge surface structure. The technical requirements are low; pre-processing and welding are omitted; the using operation is simple and convenient; the universality is good; the connection is firm; moreover, the utility model can bear pressure, and can be reliably applied under the pressure of 6.3 MPa; the connected pipeline can bear the largest working pressure of 10MPa.
Description
Technical field
The utility model relates to a kind of cassette direct connection flange, belongs to pipe joint.
Background technique
Flange is widely used as the link of pipeline.Pipeline connects employing welding manner mostly at present, needs welding equipment and welding technique personnel, and the pipe installation of long distance needs a large amount of welding equipment and welding technique personnel, and field work also is subjected to the restriction of power supply.
The model utility content
The purpose of this utility model is to provide a kind of cassette direct connection flange, and technical requirements is low, has exempted preprocessing and welding, uses easy and simple to handlely, and versatility is good, is connected firmly, can also pressure-bearing.
Cassette direct connection flange described in the utility model, two relative flange plate are arranged, flange plate is provided with attachment hole, it is characterized in that having the snap ring of suitable connecting tube, flange plate is provided with the snap ring chamber of corresponding snap ring, and snap ring is provided with pin hole, be fitted with bayonet lock in the pin hole, the length of bayonet lock is greater than the thickness of snap ring, and the outer end of bayonet lock contacts with the snap ring cavity wall, and the snap ring cavity wall is the sphenoid surface structure.
When installing and using, equipped good snap ring, bayonet lock and flange plate, use bolt that two flange plate are connected and fixed by attachment hole, by to the bolt application of force, the sphenoid surface of snap ring cavity wall compresses bayonet lock gradually, and the conversion direction of exerting all one's strength is afterburning diametrically, snap ring and pipeline are combined as a whole, finish safe, the firm connection of pipeline.Exempted preprocessing and welding, technical requirements is low, uses easy and simple to handlely, is connected firmly.
In the utility model:
Pin hole can circumferentially distribute 2-40 on snap ring, uniform force application is solid and reliable.
Between snap ring the inner and flange plate, establish the O RunddichtringO, be provided with sealing gasket between two flange plate, the enhanced leaktightness performance.
The utility model cassette direct connection flange, there is not welding, pipeline is without any processing, technical requirements is low, preprocessing and welding have been exempted, only need flange and snap ring are enclosed within on the pipeline, and get final product two end flange are fastening with bolt, use easy and simple to handlely, be connected firmly, solved field construction equipment, power supply, the restriction of conditions such as welder, improved efficiency of construction greatly, be oil, the mine, chemical industry, the construction of the open-air pipeline of industries such as coal provides great convenience, and used Sealing all can use the GB Sealing of market circulation, and it is low easily to purchase cost, versatility is good, can also pressure-bearing, can under the big pressure of 6.3MPa, reliably use, the pipeline maximum that connects can be born the working pressure of 10MPa.
Description of drawings
Fig. 1, the utility model one embodiment are combined in the structural representation under the application state.
Among the figure: 1, pipeline 2, snap ring 3, bayonet lock 4, pin hole 5, O RunddichtringO 6, sphenoid surface 7, snap ring chamber 8, bolt 9,11, flange plate 10, asbestos seal pad.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, cassette direct connection flange described in the utility model, two relative flange plate 9 are arranged, 11, flange plate 9, be respectively equipped with attachment hole on 11, connect with bolt 8 by attachment hole, if the snap ring 2 of suitable connecting tube, flange plate 9 is provided with the snap ring chamber 7 of corresponding snap ring 2, snap ring 2 is provided with pin hole 4, pin hole 4 can circumferentially distribute 2-40 on snap ring 2, as 2,3,4,6,8,10,12,16,20,22,28,30,36, or the like, be fitted with bayonet lock 3 in the pin hole 4, the length of bayonet lock 3 is greater than the thickness of snap ring 2, and the outer end of bayonet lock 3 contacts with the inwall in snap ring chamber 7, and the inwall in snap ring chamber 7 is the structure of sphenoid surface 6,9 of the inner of snap ring 2 and flange plate are provided with 5, two flange plate 9 of O RunddichtringO, be provided with asbestos seal pad 10 between 11.
When installing and using, equipped good snap ring 2, bayonet lock 3 and flange plate 9,11, use bolt 8 that two flange plate 9,11 are connected and fixed by attachment hole, by to bolt 8 application of forces, the sphenoid surface 6 of snap ring chamber 7 inwalls compresses bayonet lock 3 gradually, snap ring 2 and pipeline 1 are combined as a whole, finish safe, the firm connection of pipeline.
