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, 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 respectively provided with a flange and a threaded convex pipe joint, and bolt holes are provided 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.Be not suitable for being connected between threaded port tubing and the flange port tubing.
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, applicable to the terminal port flange that is connected between threaded port tubing and the port flange tubing.
The present invention is provided with body; Body is provided with central through bore, and the two ends of body are respectively equipped with flange and the protruding pipe joint of screw thread, and flange is provided with bolt hole.
Central through bore can be isometrical or gradual change footpath central through bore.
Flange preferably is provided with boss or the groove with the central through bore coaxial inner conductor, forms convex flange or spill flange.
The screw thread of the protruding pipe joint of screw thread can be internal thread or outside thread.
Preferably be provided with nut between the protruding pipe joint of flange and screw thread, pipe wrench mounting or dismounting easy to use.
Bolt hole preferably is provided with at least 3.
Body can be monolithic construction, also can be split modular structure, as: can be connected by fastening piece by up and down two-part or left and right sides two-part and constitute, split-type structural can more conveniently be installed and removed.
When the present invention uses, the protruding pipe of the screw thread of body is threaded with the conveying tubing that is provided with threaded port to be connected, forms the terminal port flange of carrying tubing.In the time need being connected with other conveying tubing, be provided with conveying tubing of the present invention be provided with flange other carry tubing to carry out bolt to be connected and get final product, unclamping bolt is detachably, very convenient.When the conveying tubing of need connection is provided with the flange port, generally also is furnished with the flange cover of convex or spill, the terminal port flange that is provided with conveying tubing of the present invention can correspondingly be provided with groove or boss, during connection, the terminal port flange that is provided with conveying tubing of the present invention is chimeric with the flange cover of the conveying tubing that needs to be connected, get final product with bolt locking, therefore, the present invention is applicable to being connected between threaded port tubing and the port flange tubing again.

Embodiment
Referring to Fig. 1 and 2, the present invention is provided with body 1, and the two ends that body 1 is provided with central through bore 11, body 1 are respectively equipped with flange 12 and the protruding pipe joint 13 of screw thread, and flange 12 is provided with 4 bolts hole 121.Flange 12 is provided with boss 122.The screw thread of the protruding pipe joint 13 of screw thread is an outside thread.Be provided with nut 14 between the protruding pipe joint 13 of flange 12 and screw thread, pipe wrench mounting or dismounting easy to use.Central through bore 11 is isometrical central through bore.
Referring to Fig. 3, when the embodiment of the invention is used, earlier the protruding pipe joint 13 of the outside thread of body 1 is threaded with the conveying tubing 2 that is provided with female end to be connected.Another conveying tubing 3 that needs to connect is provided with port flange 31, and is provided with spill flange cover 4.Because the flange 12 of body 1 is provided with boss 122, during connection, boss 122 will carry the flange 31 of tubing 3 to be pressed in the groove 41 of spill flange cover 4, be provided with seal ring 5 between boss 122 and flange 31, then by bolt 42 lockings.
Referring to Figure 4 and 5, similar to Example 1.Body 1 ' be provided with central through bore 11 ', body 1 ' flange 12 ' be provided with groove 122 ', the protruding pipe joint 13 of screw thread ' screw thread be internal thread.Among Fig. 5, carry tubing 2 ' be provided with male end, carry tubing 3 ' be provided with convex flange cover 4 ', the protruding pipe joint 13 of screw thread ' with carry tubing 2 ' male end be connected, convex flange cover 4 ' will carry tubing 3 ' flange 31 ' be pressed in body 1 ' groove 122 ' in, groove 122 ' and flange 31 ' between be provided with seal ring 5 ', then by bolt 42 ' locking.
In the foregoing description 1 and 2, the central through bore that described body is provided with also can be gradual change footpath central through bore, and gradual change footpath central through bore can become buffer channel, the harm that the energy jump that can avoid being produced when connecting the different conveying tubing of caliber brings.2 conveying tubing that need to connect are straight-through tube, and 2 conveying tubing also can be curved siphunculus during practical application, or various pipe joint, as straight coupling, tee union, cross fitting, 90 ° of elbows and 45 ° of pipe fittings such as elbow.Described body not only can be monolithic construction, also can be split-type structural, as: can by up and down or about two parts connect by fastening piece and constitute, split-type structural can more conveniently be installed and removed.Described body can be metalwork, also can be non-metal part as (as working of plastics), or the composite members of metal and nonmetallic material.
