Abstract

The utility model discloses an exhaust connecting pipe of an internal combustion engine. The exhaust connecting pipe comprises a pipe body, the pipe body is provided with an air inlet end and an air outlet end, the pipe body is provided with a pipe body inner layer and a pipe body outer layer, a cooling water bush is clamped between the pipe body inner layer and the pipe body outer layer, and a water inlet and a water outlet are formed in the two ends of the cooling water bush respectively. According to the exhaust connecting pipe, the temperature of the outer wall face of the pipe body can be relatively low, fire accidents of the internal combustion engine are effectively reduced, and it is ensured that the internal combustion engine is used more safely and reliably.

Description

I. C. engine exhaust is taken over

Technical field

The utility model relates to internal combustion engine part field, and particularly a kind of I. C. engine exhaust is taken over.

Background technique

Internal-combustion engine is as traditional dynamic power machine, has been widely used in communications and transportation, industry and the field such as agriculture.Yet the delivery temperature of internal-combustion engine is high, generally in (600~850) ℃ left and right, the outer wall temperature of vent connection is also in (350~600) ℃ left and right, and, from the distance of combustion engine cylinder head relief opening more close to, the temperature of vent connection outer wall is just higher.

Traditional I. C. engine exhaust adapter tube body is single-layer metal layer structure, under the effect that in pipe, the high temperature of waste gas transmits in heat, be directly delivered to tube wall face, therefore vent connection tube wall face has obtained high temperature, therefore,, once have fuel oil or the leakage of oil of machine oil pipeline, drop onto in the vent connection outer wall of these high temperature, the as easy as rolling off a log fire accident that causes, jeopardizes personal safety and property safety.

Model utility content

The utility model is in order to overcome defect in above-mentioned prior art, provide a kind of I. C. engine exhaust to take over, by accompany one deck cooling jacket between wall inside and outside I. C. engine exhaust adapter tube body, in cooling jacket, mobile cooling water can be taken away a part of heat of body, play heat insulation effect, make the temperature of vent connection tube wall face relatively low, effectively reduce internal-combustion engine accident on fire, guarantee that internal-combustion engine is more safe and reliable.

For realizing above-mentioned model utility object, the utility model provides a kind of I. C. engine exhaust to take over, this vent connection comprises body, body has suction port end and air outlet end, body has body internal layer and body is outer, between body internal layer and body skin, accompany one deck cooling jacket, at cooling jacket two ends, be respectively equipped with water intake and water outlet.

In technique scheme, water intake is located on the sidewall near the body of suction port end.

In technique scheme, water intake is opened the bottom at cooling jacket.

In technique scheme, water outlet is located on the sidewall near the body of air outlet end.

In technique scheme, water outlet is opened the top at cooling jacket.

In technique scheme, suction port end is provided with inlet flange, and air outlet end is provided with the flange of giving vent to anger, and vent connection is by inlet flange and the flange connection of giving vent to anger.

In technique scheme, vent connection is by snap ring connection.

Compared with prior art, the utlity model has following beneficial effect: by the body of vent connection is designed to double layer construction, between inside and outside body, be provided with cooling jacket, continual cooling water is ceaselessly taken away the heat of vent connection body, the outer wall temperature of body is reduced, played heat insulation effect; In addition, cooling jacket adopts the water flowing mode of " the high-order water outlet of low position inflow water ", prevents from storing in cooling jacket air, thereby guarantees that this vent connection has good, effect of heat insulation reliably.

Accompanying drawing explanation

Fig. 1 is the vent connection sectional drawing of internal-combustion engine of the present utility model;

Fig. 2 is the vent connection axonometric drawing of internal-combustion engine of the present utility model.

Mark the following drawings mark thereon by reference to the accompanying drawings:

1-water outlet, 2-body internal layer, 3-body is outer, 4-cooling jacket, 5-suction port, 6-water intake, 7-air outlet, the 11-flange of giving vent to anger, 12-inlet flange.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.

As shown in Figures 1 and 2, the body of the vent connection of internal-combustion engine of the present utility model is double layer construction, particularly, body has suction port end 5 and air outlet end 7, body comprises body internal layer 2 and body skin 3, between body internal layer 2 and body skin 3, accompany one deck cooling jacket 4, at the two ends of cooling jacket 4, be respectively equipped with water intake 6 and water outlet 1.

As a kind of embodiment, water intake is located on the sidewall near the body of suction port end, and water intake 6 is opened in the bottom of cooling jacket 4, and water intake down.Water outlet 1 is located on the sidewall near the body of air outlet end, and water outlet 1 is opened the top at cooling jacket, and water intake, can guarantee that cooling jacket is from water intake 6 water inlets in bottom, from water outlet 1 water outlet in top upward like this.

For this vent connection of connection, at suction port 5 ends, be designed with inlet flange 12, air outlet 7 ends are designed with the flange 11 of giving vent to anger, and certainly, this vent connection is except can, with flange connection, also selecting snap ring or other method connection.

When the vent connection of concrete this internal-combustion engine of use, cooling water flows into cooling jacket from water intake, after the cooling jacket of flowing through, flows out from water outlet again.Continual cooling water is ceaselessly taken away the heat of vent connection body, and the outer wall temperature of body is reduced, and has played heat insulation effect.

In addition, cooling jacket is from the water intake water inlet in bottom, from the water outlet water outlet in top, has adopted the water flowing mode of " the high-order water outlet of low position inflow water ", prevent from storing in cooling jacket air, thereby guarantee that this vent connection has good, effect of heat insulation reliably.

Disclosed is above only specific embodiment of the utility model, and still, the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
