Abstract
A slot type flange is composed of a grooved flange and a dowel pin flange. The grooved flange is composed of flange discs and a grooved cylinder, the grooved cylinder is welded on the inner circumferential side walls of the flange discs in a sealed mode, one side face of the grooved cylinder is sealed, annular grooves are formed in the other side face of the grooved cylinder, and the side face with the annular grooves is located on the same plane with the flange discs. The dowel pin flange is composed of flange discs and a dowel pin cylinder, the dowel pin cylinder is welded on the inner circumferential side walls of the flange discs in a sealed mode, a cylindrical dowel pin stretches from one side face of the dowel pin cylinder and is not located on the same plane with the flange discs, and the cylindrical dowel pin protrudes out of the plane of the flange discs. Sealing gaskets are placed at the bottoms of the grooves of the grooved cylinder, the cylindrical dowel pin is matched with the annular grooves, bolt holes are formed in the flange discs, and the grooved flange and the dowel pin flange are connected in a sealed mode through bolts.
Description
Technical field
The utility model insertion slot type flange belongs to a kind of mechanical pipe connection set.
Background technique
Flange (Flange) be again flange plate or bead, and it is between pipe or pipe and the interconnective part of valve, is connected in pipe end.Perforation on flange, bolt is close to two flanges.Between flange, with liner sealing, flange divides (silk connects) flange and welded flange and the cutting ferrule flange apparatus that be threaded.But no matter any connection, once flange is heated, excessive deformation or liner damage, and liquid (gas) Seepage will occur, and gently damage machinery, heavy cause security incident.Therefore, how by improving flange arrangement, changing mouth of pipe Placement, thereby effectively prevent liquid (gas) seepage, the stifled security incident hidden danger causing thus absolutely, has important practical significance.
Model utility content
The technical problem that the utility model need solve is: by a kind of insertion slot type flange is provided, to reduce due to flange be heated excessive deformation, or liner damage the probability that liquid (gas) seepage occurs, thereby the stifled security incident hidden danger of initiation absolutely thus.
The utility model solves above-mentioned technical problem by the technological scheme with following: insertion slot type flange is comprised of groove flange and pin flange, groove flange consists of flange plate and groove cylinder, groove cylinder seal welding is at flange plate inner circle sidewall, side seal of groove cylinder, another side have circle shape groove, and the side and the flange plate that have a circle shape groove are in same plane; Pin flange consists of flange plate and pin cylinder, pin cylinder seal welding is at flange plate inner circle sidewall, a cylindric pin is stretched out in a side of pin cylinder, and cylindric pin and flange plate be at same plane, and cylindric pin protrudes outside the plane of flange plate; Seal washer is laid in the circle shape groove bottom of groove cylinder, and cylindric pin and circle shape groove match, and have bolt hole on flange plate, by bolt, groove flange are connected with pin flange seal.
During production, the width of the wall ratio circle shape groove of cylindric pin is smaller, and the length of cylindric pin equals or be slightly less than the degree of depth of circle shape groove; During use, seal washer is laid in the circle shape groove bottom of the first groove cylinder at groove flange, again the cylindric pin of the pin cylinder of pin flange is alignd with the circle shape groove of groove flange, and cylindric pin is inserted to circle shape groove, now, the bolt hole of the bolt hole of groove flange and pin flange aligns, and penetrates bolt among bolt hole, with nut, groove flange and pin flange seal is fastening.
Accompanying drawing explanation:
Fig. 1 is the side view of groove flange, wherein:
(1), the groove cylinder of groove flange; (2), the flange plate of groove flange; (3), circle shape groove; (4), the pipeline opening of groove cylinder; (5), the bolt hole of flange plate.
Fig. 2 is the front view of groove flange, wherein:
(2), the flange plate of groove flange; (5), the bolt hole of flange plate; (6), groove seal washer.
Fig. 3 is the side view of pin flange, wherein:
(7), pin cylinder; (2), the flange plate of pin flange; (8) cylindric pin.
Fig. 4 is the front view of pin flange, wherein:
(2), the flange plate of pin flange; (4), the pipeline opening of pin cylinder; (5), the bolt hole of flange plate.
Embodiment:
The utility model insertion slot type flange is comprised of groove flange and pin flange, groove flange consists of flange plate (2) and groove cylinder (1), groove cylinder (1) seal welding is at flange plate inner circle sidewall, side seal of groove cylinder, another side have circle shape groove (3), and the side and the flange plate (2) that have a circle shape groove (3) are in same plane; Pin flange consists of flange plate (2) and pin cylinder (7), pin cylinder (7) seal welding is at flange plate (2) inner circle sidewall, a cylindric pin (8) is stretched out in a side of pin cylinder (7), and cylindric pin (8) is not with flange plate (2) at same plane, and cylindric pin (8) protrudes outside the plane of flange plate (2); The bottom portion of groove of groove cylinder is laid seal washer (6), and cylindric pin (8) matches with circle shape groove (3), has bolt hole (5) on flange plate, by bolt, groove flange is connected with pin flange seal.
During production, the width of the wall ratio circle shape groove (3) of cylindric pin (8) is smaller, and the length of cylindric pin (8) equals or be slightly less than the degree of depth of circle shape groove (3); During use, seal washer (6) is laid in circle shape groove (3) bottom of the first groove cylinder (1) at groove flange, again the cylindric pin (8) of the pin cylinder (7) of pin flange is alignd with the circle shape groove (3) of groove flange, and cylindric pin (8) is inserted to circle shape groove (3), now, the bolt hole of groove flange (5) aligns with the bolt hole (5) of pin flange, and penetrate bolt among bolt hole (5), with nut, groove flange and pin flange seal is fastening.
