Leakage detection flange for oil return pipe of schematic turbocharger

Referring to fig. 1 to 3, according to the present invention, the turbocharger oil return pipe leakage detecting flange according to a preferred embodiment of the present invention includes a flange body 10, the flange body 10 has a bottom plate 11 and a connecting end 12, the bottom plate 11 is located at an oil port of the external turbocharger, and the connecting end 12 is located on a side of the bottom plate 11 deviating from the external turbocharger, wherein it should be noted that the connecting end 12 is connected to the external oil pipe.

Further, the connecting plate is located in the middle of the side of the bottom plate 11 facing away from the external turbocharger.

Further, the bottom plate 11 is dart-shaped.

It should be noted that, one side of the bottom plate 11 away from the external turbocharger is further provided with two first reinforcing portions 111 arranged oppositely, the connecting end 12 is located between the two first reinforcing portions 111, and a side of the two first reinforcing portions 111 close to each other is spaced from the connecting end 12 by a predetermined distance.

One side of the bottom plate 11, which is away from the external turbocharger, is further provided with two second reinforcing parts 112 which are arranged oppositely, one side of the second reinforcing parts 112, which is away from each other, is respectively connected with one side of the first reinforcing parts 111, which is close to each other, and one side of the second reinforcing parts 112, which is close to each other, is respectively connected with two sides of the connecting end 12. It is worth mentioning that both the first reinforcing parts 111 and the second reinforcing parts 112 are used to improve the structural strength of the bottom plate 11.

It should be mentioned that the first reinforcing portion 111 and the second reinforcing portion 112 are both arc-shaped, and the notch of the first reinforcing portion 111 is located on the side of the first reinforcing portion 111 departing from the second reinforcing portion 112.

Further, the bottom plate 11 further has two positioning holes 1101, the two positioning holes 1101 both penetrate through the bottom plate 11, the two positioning holes 1101 are respectively located at two ends of the bottom plate 11, and the two positioning holes 1101 are further respectively located near the two first reinforcing portions 111. Two of the positioning holes 1101 are used to fix the bottom plate 11 to the wall surface of the turbocharger where the oil port is provided.

It should be noted that an end of the connecting end 12 facing away from the bottom plate 11 has a fitting hole 101 and an oil passage 102, and the fitting hole 101 communicates with the oil passage 102. The assembly hole 101 is connected to an external oil pipe, and the oil passage 102 penetrates the bottom plate 11 and faces an oil port of an external turbocharger. Wherein, as will be understood by those skilled in the art, the external turbocharger has a contact surface, and the oil port is located on the contact surface, while the side of the bottom plate 11 facing away from the connecting end 12 is fixedly connected with the contact surface, and the end of the oil passage 102 facing away from the assembling hole 101 is opposite to the oil port. The sealing structure of the oil return pipe welding sealing flange of the turbocharger which is common at present is assembled and sealed through a traditional end face sealing groove and a sealing ring. This kind of form structure is the unable discernment sealing washer of product itself whether neglected loading, and the seal groove size has the deviation to lead to influencing sealing performance, and traditional pressure testing can't discern. In addition, the accuracy requirement on the side leakage equipment is high, the cost is high, and the side leakage equipment may also have the problem of side leakage failure.

And the utility model discloses can be effectively the defect that exists among the wall prior art, specifically say, bottom plate 11 deviates from one side of link 12 has a ring channel 1102 and a arch 113, arch 113 is located the center of ring channel 1102, just oil duct 102 deviates from the one end of pilot hole 101 is run through arch 113. I.e. with the end of the oil channel 102 facing away from the fitting hole, in the center of the protrusion 113. Wherein it will be understood by those skilled in the art that the contact surface of the external turbocharger has an annular protrusion 113 that mates with the annular groove 1102, i.e. when the base plate 11 mates with the contact surface of the external turbocharger, the annular protrusion 113 mates with the annular groove 1102, while the end of the oil passage 102 facing away from the bore of the fitting is directly opposite the port of the contact surface.

It should be noted that the protrusion 113 further has a side leakage groove 11301, and two ends of the side leakage groove 11301 are respectively communicated with the oil passage 102 and the annular groove 1102. It should be further noted that the wall surface forming the annular groove 1102 is further provided with a notch 1103, and the notch 1103 is respectively communicated with the outside and the annular groove 1102. And whether traditional assembly structure is installed or is lost efficacy to the sealing washer and can't effectively discern, and traditional pressure testing can't discern whether the sealing washer is installed or is lost efficacy promptly, and then leads to needing the side leakage equipment of high accuracy, and then leads to the cost-push.

Further, the side leakage grooves 11301 are arc-shaped.

It should be noted that, due to the existence of the side leakage groove 11301 and the notch 1103, a user can perform a leakage detection test more conveniently. Specifically, when no sealing ring is arranged in the annular groove 1102 or the sealing ring fails, that is, when no sealing ring is arranged between the annular protrusion 113 and the wall surface of the annular groove 1102, a leakage problem occurs, so that a side leakage medium flows from the oil passage 102 to the annular groove 1102 through the side leakage groove 11301 and flows to the notch 1103 along the annular groove 1102, and the leakage problem is quickly found, so that the unqualified flat surface is quickly detected.

In conclusion, based on this application embodiment the turbo charger returns oil pipe flange of leaking hunting is elucidated, it does the turbo charger returns oil pipe flange of leaking hunting provides advantages such as simple structure, practicality height, the cost of leaking hunting is low, the effect of leaking hunting is good.

It is worth mentioning that, in the embodiment of the present application, the turbocharger oil return pipe leakage detection flange has a simple structure, does not involve a complicated manufacturing process and expensive materials, and has high economical efficiency.
