The elastic sealing rings are made by metal and respectively provided with an opening, and the openings of two adjacent elastic sealing rings are staggered. A circumferential lug boss is arranged on the port of the front exhaust pipe, and the grooves are arranged on the outer circumferential surface of the lug boss. The port of the back exhaust pipe is formed by a flange of a pipe body, which is outward along a radial direction and axially forward. The connecting mechanism, provided by the invention, has the advantages of fewer parts, simple structure, convenience for mounting and dismounting, reliable sealing property and a certain bearing capacity, when the connecting mechanism is installed, the connecting mechanism is not limited by an arrangement space, and is suitable for assembly connection of the exhaust pipes of the diesel engine.
Description
Technical field
The present invention relates to the oil pumping unit technical field, relate in particular to a kind of Diesel Engine Exhaust Pipe bindiny mechanism.
Background technique
Diesel Engine Exhaust Pipe is positioned at the diesel engine top, is the passage of dual fuel of diesel engine.Because diesel engine, particularly the V-type diesel head room is limited, when confirming the form that outlet pipe connects, need consider whether its space and whole assembly technology meet the requirements, and will guarantee the sealing of joint between the outlet pipe tube and tube.
The outlet pipe Placement mostly connects for flange plate at present; Big bellows with the double-layer thin wall structure between adjacent two joint outlet pipes connects; The neck bush of this bellows is to be sleeved in the bellows, and lining flange, gasket seal and bellows flange fit tightly during assembling.Its advantage of the connection of this flange plate mode is that structural strength is big; Bearing capacity is strong; But, its structure could guarantee sealing because of needing to increase between two flanges gasket seal; And outlet pipe is in working order down owing to be heated and the influence of exhaust pressure, bolt looseness occurs or the outlet pipe gasket seal is washed out through regular meeting, causes fault generating such as outlet pipe gas leakage; See that from arranging flange plate is generally big than caliber, need bigger installing space, can not meet the demands in this Placement of some special narrow space.
Summary of the invention
The technical problem that the present invention solved provides a kind of simple in structure, Diesel Engine Exhaust Pipe bindiny mechanism of being applicable to small space.
The technological scheme that the present invention adopts is an a kind of Diesel Engine Exhaust Pipe bindiny mechanism; Two outlet pipes that comprise mutual butt joint; Wherein the port of front exhaust pipe inserts in the port of final vacuum pipe, and the port of the front exhaust pipe outside is provided with at least three road annular grooves, is provided with elastic sealing ring in the groove; The inwall of elastic sealing ring snaps in the groove, and the outer wall of elastic sealing ring is compressed by the inwall of final vacuum tube opening.
Elastic sealing ring is made of metal.
Elastic packing is equipped with an opening, and the interleaved openings of adjacent two elastic sealing rings distributes.
Elastic sealing ring quantity is 3, the 90 ° of distributions of respectively being separated by of the opening of adjacent two elastic sealing rings.
The port of front exhaust pipe is provided with circumferential boss, and groove is arranged on the boss outer peripheral surface.
The port of final vacuum pipe is formed by the radially outwards also axial flange forward of body.
One end of outlet pipe is a boss, and the other end is a flange.
The invention has the beneficial effects as follows that number of spare parts is few, simple in structure, installation and removal are all very convenient, have reliable sealing performance and certain bearing capacity, do not receive the restriction of arrangement space during installation.

Fig. 3 is an outlet pipe three-dimensional structure diagram of the present invention.
Fig. 4 is an elastic sealing ring mechanism map of the present invention.
Be labeled as among the figure: the 11-front exhaust pipe, 12-final vacuum pipe, the 2-elastic sealing ring, the 3-flange, the 4-boss, the 21-opening,
Embodiment
As shown in Figure 1, former and later two outlet pipes embed to install along axis and connect, and the port of front exhaust pipe 11 inserts in the port of final vacuum pipe 12.Wherein the port of front exhaust pipe 11 outside is provided with at least three road annular grooves; Be provided with elastic sealing ring 2 in the groove; The inwall of elastic sealing ring 2 snaps in the groove, and the outer wall of elastic sealing ring 2 is compressed by the inwall of final vacuum pipe 12 ports, and elastic sealing ring can be selected alloy cast iron material for use.
There is outside flange 3 port of final vacuum pipe 12, is formed by the radially outwards also axial flange 3 forward of body.Front exhaust pipe 11 circumferentially is provided with boss 4, three road annular grooves in its port along it and is arranged on the boss 4.The internal diameter that can guarantee exhaust duct like this is consistent, and it is unobstructed to help exhaust, on boss 4, offers the intensity that groove helps guaranteeing jointing simultaneously, compact overall structure, and it is less to take space outerpace.If make groove embed the body of outlet pipe, keep the exhaust duct external diameter consistent simultaneously, can more adapt to narrow space, but the structure of jointing will inevitably influence the exhaust duct internal diameter, be unfavorable for that exhaust is unobstructed.One end of outlet pipe is a boss 4, and the other end is a flange 3, convenient production, and assembling interchangeability is good.
The boss 4 that front exhaust pipe 11 is equipped with elastic sealing ring 2 embed final vacuum pipes 12 flange 3 in; Elastic sealing ring 2 internal surfaces contact with the groove outer surface, and flange 3 inwalls of the external diameter of seal ring and final vacuum pipe 12 are fitted and received the inside compacting of flange 3 of final vacuum pipe 12.Elastic sealing ring 2 is a kind of metallic elastic rings that expand outwardly distortion more greatly that have; Three elastic sealing rings 2 embed respectively in three grooves on the boss 4; Elastic sealing ring 2 jointings have the opening 21 of certain interval, and the inwall of the external diameter of elastic sealing ring 2 and flange 3 is fitted.Be to guarantee the airtight effect of seal ring, opening 21 positions of three seal rings are staggered 90 ° successively, if more than three seal rings, then the angle that staggers mutually of opening 21 can be selected separately.The sealing principle of elastic sealing ring 2 is throttling and obstruction two aspects.The external diameter of elastic sealing ring 2 and outlet pipe flange 3 inwalls are fitted the back by blocking action, lean on the throttling action of gas between the end face of ring and the annular groove, play seal action jointly.Number of spare parts of the present invention is few, and is simple in structure, and installation and removal are all very convenient.
