Abstract
A port flange of a delivery pipe relates to a part for connecting the delivery pipe, particularly a flange for connecting the delivery pipe. The invention provides a port flange which can be conveniently dismounted, slowly changed in diameter, and suitable for connecting a threaded port tubular product with a port flanging tubular product. The port flange comprises a body, and a central through hole processed on the body, wherein the two ends of the body are provided with flanges, and bolt holes are arranged on the flange.
Description
Technical field
The present invention relates to a kind of accessory that connects delivery pipe, relate in particular to a kind of flange that connects delivery pipe.
Background technique
At present, connection between the delivery pipe generally has three kinds of modes: 1, directly welding: will carry out in the erecting bed when directly welding, generally will carry out trial assembly, welding, removing welding slag, series of processes such as pickling, back dismounting inconvenience is installed, and welding quality is difficult for checking.2, pipe joint connects: generally be applicable to the delivery pipe of minor diameter, Welded fitting, Bite type fittings, flared fitting etc. are arranged usually, these modes all are by being threaded of making on fittings body and the tubing, the precision prescribed height, the assembly technology complexity, easy damaged tubing, cost height.3, flange connects: reliable operation, mounting or dismounting are convenient, but often will weld out or cast out flange at the port of delivery pipe, make the required precision height, increase cost.
If when adopting this fixed flange to interconnect, the mounting or dismounting repair and maintenance are very inconvenient.
In addition, the flange that just will be located at 2 ports of carrying tubing when general flange connecting apparatus uses connects by bolt locking more directly to leaning on.There is following shortcoming in this flange connecting apparatus: if 2 caliber differences of carrying tubing, when especially difference is big, when fluid flows through the junction plane of 2 conveying tubing, it is unexpected that reducing can take place, energy jump, fragile conveying tubing and flange apparatus, and easily form the coefficient of partial resistance increase, therefore not too be fit to carry the reducing of tubing to connect.In addition, general flange connecting apparatus not too is applicable to the connection of the conveying tubing of port flange.
Notification number provides a kind of shaping round tube flange apparatus for the utility model patent of CN2161798.This device is made up of a pair of annular flange, a lock uint and an airtight pad.On annular flange, be provided with,, be provided with containing groove, utilize the extension annular lamina of containing groove leading edge will extend annular lamina and the various forms that knot of circular duct ora terminalis machine shaping by facility in the annular flange lower end so that annular flange is connected with binding block in conjunction with otch; The oblique angle of being made up of two annular flange upper inclined surface is in the reversed V-shape ring of lock uint, is convenient to assembly two airducts; Add the airtight pad that is between two annular flanges and can prevent effectively that air-flow from leaking, and engage firmly.
Notification number provides a kind of FERRULETYPE fast-assembling piping flange for the utility model patent of CN2466472, form by flange cover dish, pressure ring, collar, seal ring, flange cover dish is enclosed within on the pipe, carve several roads groove in the pipe termination, collar is put into the pipe groove, the two halves pressure ring closes, the pressure ring inboard wall groove is dropped on the collar, to push away before the flange cover dish, be inserted in the two halves pressure ring and combine and put in place, seal ring is inserted in pipe end, connect another flange plate with bolt with pressure ring, fix in the pipe termination, therefore quick and easy for installation.
Summary of the invention
The purpose of this invention is to provide a kind ofly install and remove conveniently, can gradual footpath, carry the connection of tubing to carry the flange of tubing applicable to the port flange.
The present invention is provided with body; Body is provided with central through bore, and the two ends of body are flange, and flange is provided with bolt hole.
Central through bore is preferably gradual change footpath central through bore.
The flange at body two ends preferably is provided with boss or the groove with the central through bore coaxial inner conductor, forms convex flange or spill flange, and body can be lenticular flange body, double concave flange body or convex-concave flange body.
Bolt hole preferably is provided with at least 3.
Body is a monolithic construction, also can be split modular structure, as: can be connected by fastening piece by two-part or left and right sides two-part combination up and down and constitute, split-type structural can more conveniently be installed and removed.
When the present invention works, must use to reach goal of the invention with the flange combination that is arranged on the conveying tubing.For example, when needs carry tubing to connect with 2, carry the port of tubing to be equipped with flange for 2,2 flanges at two ends of the present invention are connected with 2 flange bolts of carrying the port of tubing respectively get final product.Install and remove very convenient.Because the set center hole of the present invention can be transition passage isometrical or the gradual change footpath, so can form buffer channel, so just can avoid 2 directly energy jump, local resistances of minimizing current of port of carrying tubing to being taken place because of the caliber difference by connection, reduce the head total losses, the damage that can effectively avoid carrying tubing and flange apparatus.When the port of the conveying tubing of required connection is turnup structure, 2 are carried pipe end generally is to be provided with convex flange cover or spill flange cover, the conventional connection is to carry the set respectively convex flange cover of pipe end chimeric mutually with spill flange cover with 2, connect by bolt again, if between 2 convex flange covers of carrying pipe ends overlap with the spill flange, set up the present invention, because 2 flanges of the present invention can be provided with groove or boss structure, so 2 flanges of the present invention can be carried the convex flange cover of pipe ends with 2 respectively and spill flange cover is mutual chimeric and be connected by bolt, therefore, the present invention is highly suitable for the connection that the port flange is carried tubing.
