Abstract
A flange anti-drip new product is a novel pressure pipeline component. Annular bosses which are parallel with a flange periphery and corresponding to annular grooves are disposed on butt joint faces. Structural positions of the grooves and bosses of a pair of flanges engage with each other. Cross sections of the engaged grooves and bosses are trapezoid shaped, a half boss and a half groove are disposed at a drift diameter of the flange and an outer diameter of the butt joint faces, and semi-finished products to be processed is the same as raised face flanges in thickness. A connection part and a welded pipe surface of the flange move horizontally and axially along the flange towards the butt joint face, and the half boss at the outer diameter of the flange butt joint face is a shallow half groove, such that pipe fittings or valve integral members with raised face flanges can be used as semi-finished integral members with anti-drip flanges for treatment and ultimately processed into semi-finished integral members with anti-drip flanges. The flange anti-drip new product can help reduce manufacturing costs and is beneficial to the popularization of the anti-drip flanges.
Description
Affiliated technical field
The flange leakage-proof new product of the utility model is a kind of novel pressure piping components and parts, is traditional new product that forms after the prominent face steel pipe flanges transformation of using always, is the new product element that the dripping-proof flange technology is innovated again.
Background technique
China's patent application 200610006517.7 open days: on September 6th, 2006; Notification number: CN1828114A and 200810109675.4 open days: on January 7th, 2009; Notification number: the content that CN101338841A narrated; The dripping-proof flange interface is provided with and is parallel to the flange circumference, annular groove and the corresponding annular boss that is parallel to the flange circumference.One pair (two flange plates) groove of flange and the locations of structures of boss are mutual interlocks.The groove of interlock and the truncation surface of boss are trapezoidal, and flange latus rectum and interface outer radius have half platform, half groove, and flange can form interference fit joint after giving tight connection.Dripping-proof flange need not fill up; Many conical surfaces are arranged; Interference fit joint is arranged, and bolt is loose not to be leaked yet.So long as acceptable product, in the use bolt pine in time tighten, leak-down rate is zero under the normal condition.Screw thread is arranged in the bolt hole, during dismounting with bolt to the top mode, very convenient; The thread bush dripping-proof flange is arranged.Since be provided with on the dripping-proof flange interface groove boss and prominent face flange compared thicker.If pressure piping will use dripping-proof flange to connect; Because variation has taken place in the base dimension of flange thickness; Element, the vitals that contains flange must design again, make again, and instrument, mould, manufacturing equipment all must adapt with it, and it is very high to contain dripping-proof flange single piece single-piece manufacture cost; Because pressure piping components and parts kind specification is various, it is quite big to promote the dripping-proof flange difficulty again.
Summary of the invention
In order to let people use the benefit of dripping-proof flange early, the utility model provides flange leakage-proof new product product, and it can reduce the popularization that manufacture cost is of value to dripping-proof flange.
The flange leakage-proof new product of the utility model is: be half groove with flange latus rectum place; Flange interface outer radius is on the dripping-proof flange sheet of half platform; Interface external diameter circumference promptly has the place of bolt hole to the flange outer diameter circumferential section, is to be used for the connection of flange partly (to call in the following text; Flange connects partly) and welded tube face, along flange shaft to the translation of interface direction.Translation distance is 0---18 millimeters.Can make the semi-finished product of dripping-proof flange sheet to be processed consistent with the thickness size of prominent face flange commonly used after the translation, so just can use prominent face flange plate, the semi-finished product of regarding dripping-proof flange finally are processed into dripping-proof flange.Also can be said to is that interface integral body bounces back 0 to the welded tube direction---18 millimeters.Can use the pipe fitting of the prominent face flange of band or the single piece of valve like this, handle the single piece that finally is processed into the band dripping-proof flange as the semi-finished product single piece of band dripping-proof flange.Flange connects partly and the welded tube face, along flange shaft to the translation of interface direction.Translation distance should be the thickness difference of original dripping-proof flange and corresponding prominent face flange specific on the every flange.Flange connects partly and the welded tube face; To can both making to welded tube direction retraction to the translation of interface direction or interface integral body, is that half groove interface outer radius be the thickness of the flange plate of half platform dripping-proof flange with the thickness of unidimensional commonly used prominent face flange equate with flange latus rectum place along flange shaft.Flange interface outer radius has increased shallow half groove, so flange interface outer radius has shallow half groove.
Another kind method; Be that prominent face flange coupling part and interface junction are provided with matching thread, interface is processed into the method for dripping-proof flange pattern.Also can be said to is that matching thread hole enlargement by the thread bush dripping-proof flange becomes the result who forms to the phase translation of interface side behind the interface diameter dimension.No matter be that consequently there is matching thread flange coupling part and interface external diameter junction to assorted petty reason.And two flanges can be provided with matching thread.
The beneficial effect of the utility model is; Top method can both make the thickness of dripping-proof flange a slice flange wherein; Consistent with corresponding prominent face flange thickness; Make dripping-proof flange yield to the thickness size difference of the prominent face flange of band, also just be equivalent to yield to modern industry pressure piping element user mode.Can make prominent face flange be processed into dripping-proof flange, thereby reduce the dripping-proof flange processing cost, be very beneficial for the popularization of dripping-proof flange.
