Abstract
The invention discloses an exhaust pipe snap ring type seal connecting piece. The exhaust pipe snap ring type seal connecting piece comprises a ferrule and snap springs, wherein 4-6 snap springs are provided, and respectively coat the two ends of the ferrule. The exhaust pipe snap ring type seal connecting piece is simple in structure; and by dint of the tension and the extension effect of the snap rings, the snap rings still can be tightly bonded with the inner wall of an exhaust pipe, so that exhausted waste gas can be sealed in the exhaust pipe connecting place without being leaked from the sealing surface. The exhaust pipe snap ring type seal connecting piece improves the connecting mode and the tightness of the exhaust pipe, and promotes the engine reliability.
Description
Technical field
The present invention relates to high power engine equipment technical field, especially a kind of outlet pipe retained seal closure.
Background technique
Along with the development of high power engine, also can improve the requirement of component, the difficulty of processing is also along with increasing, and outlet pipe is exactly one of them thereupon.General high power engine is made up of multiple cylinder cap, and domestic a lot of producer takes all-in-one-piece outlet pipe, but due to outlet pipe span long, casting difficulty is large, and reject rate is high, adds the planeness being difficult to ensure card relief opening sealing surface man-hour.And the outlet pipe of split, the connection between tube and tube is most important again, otherwise, out-of-flatness is installed and then easily washes out pad, cause how high-temperature exhaust air, affect the normal operation of motor.And integral for more piece exhaust stack its sealing of guarantee not being affected working life, connection part is most important.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of outlet pipe retained seal closure, structure is ingenious, easy to use.
In order to realize foregoing invention object, the invention provides following technological scheme: a kind of outlet pipe retained seal closure, comprise cutting ferrule and snap ring, described snap ring is provided with 4 ~ 6, is set in described cutting ferrule two ends respectively.
Further, described cutting ferrule periphery wall is provided with the annular groove corresponding with described snap ring.
Further, described snap ring cross section is trapezoidal, and inwall width is less than outer wall.
Further, described snap ring hoop is provided with the opened gap of 0.3 ~ 0.6mm.
Compared with prior art, the present invention has the following advantages: structure is simple, and utilize tension force and the stretchability effect of snap ring, snap ring still can fit tightly with outlet pipe inwall, the waste gas of such discharge also can be sealed in outlet pipe joint, cannot spill from sealing surface.The present invention improves Placement and the sealing of outlet pipe, promotes the reliability of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of outlet pipe retained seal closure as shown in Figure 1, comprise cutting ferrule 1 and snap ring 2, described snap ring 2 is provided with 4 ~ 6, is set in described cutting ferrule 1 two ends respectively.
This closure is that clasp type is flexible coupling mode.This sealing fitting is assemblied in the end face inner bore of two joint outlet pipes 3, respectively fills the snap ring 2 of 2 ~ 3 at ring set 1 two ends, rely on the tension force of snap ring 2, closely snap ring 2 and outlet pipe 3 are sealed.Cutting ferrule 1 outer wall is processed with the annular groove corresponding with snap ring 2, and snap ring 2 freely can rotate in annular groove
The cross section of snap ring 2 is trapezoidal, and especially inwall width is less than the width of outer wall; When engine operation, the air pressure in outlet pipe 3 is attached to snap ring 2 in annular groove tightly, and the high-temperature gas in outlet pipe is sealed in inside outlet pipe.
Snap ring 2 is the opened gap that hoop is provided with 0.3 ~ 0.6mm, avoids snap ring 2 stuck under exhaust high temperature, can play good seal action again.
Because trapezoidal snap ring freely can rotate movement in annular groove, just solve due to machining error well, cause the out of line problem of two joint outlet pipes, when avoiding assembling, outlet pipe is stressed inconsistent and cause fracture.Simultaneously due to tension force and the stretchability effect of snap ring, snap ring still can fit tightly with outlet pipe inwall, and the waste gas of discharging so also can be sealed in outlet pipe joint, cannot spill from sealing surface.
The present invention solves the split type outlet pipe of high power engine and is connected sealing problem, and high-power type is all multicylinder engine, is generally made up of the cylinder cap of more than 2.Owing to being hard link between outlet pipe and cylinder cap, what the connection between so split type outlet pipe then adopted is be flexible coupling.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (4)
1. an outlet pipe retained seal closure, is characterized in that: comprise cutting ferrule and snap ring, and described snap ring is provided with 4 ~ 6, is set in described cutting ferrule two ends respectively.
2. outlet pipe retained seal closure as claimed in claim 1, is characterized in that: described cutting ferrule periphery wall is provided with the annular groove corresponding with described snap ring.
3. outlet pipe retained seal closure as claimed in claim 1, is characterized in that: described snap ring cross section is trapezoidal, and inwall width is less than outer wall.
4. outlet pipe retained seal closure as claimed in claim 1, is characterized in that: described snap ring hoop is provided with the opened gap of 0.3 ~ 0.6mm.
