Abstract
The utility model discloses a rotary elbow for a flange hinge. A joint tube at one end of an elbow tube is the joint tube which is provided with an inserted spina groove, a connecting tube at the other end of the elbow tube is hinged in seal in a flange casing tube which is provided with a nut end tube, and the casing tube which is corresponding to the elbow tube is rotated mutually. The rotary elbow is used on an air inlet tube of a gas cooker, can seal a ring and can also change optionally the air inlet direction of the air source, and has the advantages of convenient operation and reliable and safe installation.
Description
The utility model relates to the improvement of connection pipe fitting, the hinged Rotating bend of specifically a kind of flange, and it belongs to technical field of operating transport.
The suction tude joint of existing gas cooker all is the adaptor tube of shape always.Air hose is plugged on this pipe, easily bending and cause gas transmission not smooth, and what have is easy to the jackknifing pneumatic tube, hurts sb.'s feelings so that causes fire and gas leakage takes place.Bend pipe tools of the prior art all is a tilt fixing, in case installation in position, condominium mouth direction just can not change, and this is not too convenient to using.
The purpose of this utility model is will provide a kind of Rotating bend to solve the suction tude joint to take over the fixing drawback of direction.This elbow can be sealedly connected on the adaptor tube, can change the airintake direction of source of the gas pipe again arbitrarily, and can the jackknifing air hose, safety again easy to install and use.
Task of the present utility model is finished by following technological scheme, developed the hinged Rotating bend of a kind of flange, one end connector pipe of its bend pipe is the adaptor tube that has grafting sour jujube ditch, the other end adaptor tube sealing of this bend pipe is hinged in the flange sleeve that has the nut end pipe, and this sleeve pipe rotates mutually relative to this bend pipe.
The adaptor tube of the described bend pipe the other end, its pipe outer wall is provided with the protruding circle of rectangular cross-section, and this protruding circle can be inlaid in the flange sleeve.
Described flange sleeve, it is that an end is the nut end pipe, the other end is the disjunctor sleeve pipe of flange cover platen, on the pipe end flange Pan Kou of this sleeve pipe, be provided with the hole enlargement groove, on the outer flange dish end face of this groove, by two pieces of bolton flange cover pressing plate arranged at least, constituted the protruding circle on the setting-in elbow pipe between the bottom land anchor ring of the inner side surface of this pressing plate and this groove, seal ring is or/and the spill hinged groove of spring washer.
Described flange sleeve, the profile of its flange plate or ovalize, or rounded, or be the chamfering rhombus, or be the chamfering rectangular, or be the chamfering square.
Rotating bend of the present utility model, its advantage and good effect are that simple in structure, each parts reasonable set seals tight.Because the hole enlargement groove on the flange plate mouth of flange sleeve overlaps the spill hinged groove that constitutes between the pressing plate with flange, the protruding circle on can setting-in bend pipe the other end adaptor tube, seal ring is or/and spring washer.With regard to having formed the sealing of this protruding circle is stopped up and hinged effect like this, and then hinged company lives whole bend pipe admittedly.Whole bend pipe is the rail wheel of rotation with the protruding circle on its adaptor tube, and rotates any direction in this spill hinged groove, thereby makes the adaptor tube of the band grafting sour jujube ditch of bend pipe change direction in 360 degree scopes, to adapt to the installation requirements of different direction.This Rotating bend is applied to can seal on the suction tude of gas cooker, can change the airintake direction of source of the gas pipe again arbitrarily, and is easy to use.This elbow structure is reasonable, and the unobstructed resistance of conveyance fluid (particularly coal gas) is little, and its heat flow percentage reaches 98% after tested, far surpasses 88% index of general elbow.
Embodiment's accompanying drawings of the present utility model is as follows:
Fig. 1 partly cuts open figure for the hinged Rotating bend structure of flange.
Fig. 2 is the hinged Rotating bend structure right elevation of flange.
The hinged Rotating bend of flange that the coal gas gas cooker of making referring to Fig. 1-2 is used, an end connector pipe 4 of its bend pipe is the adaptor tube 4 that has grafting sour jujube ditch 6.The other end adaptor tube 11 sealings of this bend pipe are hinged in the flange sleeve 10 that has nut end pipe 1, and this sleeve pipe 10 rotates mutually relative to this bend pipe.
The adaptor tube 11 of the bend pipe the other end that this Rotating bend is designed, its pipe outer wall is provided with the protruding circle 7 of rectangular cross-section, and this protruding circle 7 can be inlaid in the flange sleeve 10.Designed flange sleeve 10, it is that an end is a nut end pipe 1, its gabarit is the hexagon prism hat; The other end is the disjunctor sleeve pipe of flange cover platen 3,9.On the pipe end flange Pan9Kou of this sleeve pipe 10, be provided with hole enlargement groove 8.On outer flange dish 9 end faces of this groove 8, be fastened with flange cover pressing plate 3 by two pieces of bolts 5 at least.Constituted the protruding circle 7 on the setting-in adaptor tube 11 between the bottom land anchor ring of the inner side surface of this pressing plate 3 and this groove 8, seal ring 2 is or/and the spill hinged groove of spring washer (not drawing among the figure).The profile of flange plate 9 that this Rotating bend is designed and flange cover pressing plate 3 is the chamfering rhombus.The protruding circle 7 that is inlaid on the adaptor tube 11 in this hinged groove is a track with this hinged groove, returns three-sixth turn arbitrarily and do not leak combustion gas to reach easy to use, safe and reliable effect.
