Abstract
The utility model discloses a water interlayer exhaust pipe with a protective device. An air hole is formed in the surface of the water interlayer exhaust pipe, the air hole is connected with one end of an air pipe, and the other end of the air pipe is connected with an expansion tank. According to the water interlayer exhaust pipe with the protective device, water vapour in an external pipe of the water interlayer exhaust pipe can be discharged, and the problems that welding positions crack and water leakage occurs due to the fact that the cooling effect of the part of the water interlayer exhaust pipe is poor are effectively solved.
Description
Technical field
The utility model relates to a kind of water interlayer outlet pipe that has protective gear, belongs to the outlet pipe field.
Background technique
The exhaust gas temperature that diesel engine is discharged when it is applied to some inflammable and explosive occasions, need be carried out explosion-proof processing up to 650 degrees centigrade.What present explosion-proof class outlet pipe extensively adopted is the water interlayer outlet pipe, pipe and outer tube in comprising, interior pipe ventilation, outer tube water flowing cooling.Waste gas passes through from interior pipe, and outer tube offers water intake and water outlet, and cooling water flows into from water intake, and water outlet flows out, and lowers the temperature to waste gas.Waste gas enters follow-up exhaust-gas treatment system through the water interlayer outlet pipe.
But flash to water vapour owing to engine high-temperature causes the water in the outer tube, water vapour row can cause water interlayer outlet pipe part to cool off when not coming out.Weld can't stand that because of holding high temperature cracks.Last water interlayer outlet pipe can produce inner water leakage phenomenon, and causes vent systems not have the effect of cooling cooling, can cause diesel engine to damage because of inner inlet when serious.
The model utility content
Model utility purpose: the utility model proposes a kind of water interlayer outlet pipe that has protective gear, can effectively solve in the water interlayer outlet pipe water vapour and can't discharge and cause weld to crack, the problem of leaking.
Technological scheme: the technical solution adopted in the utility model is a kind of water interlayer outlet pipe that has protective gear; it comprises water interlayer outlet pipe, vent, breathing pipe and swelling water tank; a vent is offered on described water interlayer outlet pipe surface; vent links to each other with breathing pipe one end, and the other end of breathing pipe is connected with swelling water tank.
Surface at the water interlayer outlet pipe also is provided with vent, and an end of vent is communicated with the externally connected pipe of water interlayer outlet pipe, and the other end is connected with breathing pipe, and more firm with being connected of breathing pipe in order to make, the outer surface of this end also is provided with screw thread.Breathing pipe one end connects vent, and the other end connects swelling water tank.Water vapour in the externally connected pipe can enter in the swelling water tank by vent and breathing pipe like this, gradually cooling.
Beneficial effect: the utility model is discharged the water vapour in the externally connected pipe by at water interlayer outlet pipe upper surface vent being set, and it is not good to efficiently solve in the water interlayer outlet pipe local cooling effect, and causes weld to crack, the problem of leaking.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional drawing of water interlayer outlet pipe in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1; the whole water interlayer outlet pipe that has protective gear comprises water interlayer outlet pipe 1, vent 2, breathing pipe 3 and swelling water tank 16; water interlayer outlet pipe 1 adopts stainless steel material to make; being made of adjacent externally connected pipe 8, inner connecting tube 9 and other parts, is inside ceiling panel 5 between inner connecting tube 9 and the externally connected pipe 8.One end of water interlayer outlet pipe 1 is connected with the relief opening of diesel engine by suction port 15, and the other end connects follow-up exhaust-gas treatment system by flange 7.After waste gas enters inner connecting tube 9 by suction port 15, under the drainage of inside ceiling panel 5, relief opening bent plate 6 and the aeroscopic plate 10 of bending, flow to air outlet 17 1 sides.Externally connected pipe 8 is provided with joint 12 and 90 degree elbows 4 in the position at externally connected pipe 8 two ends between roof sheet 11 and inside ceiling panel 5, cooling water flows into from joint 12, behind the whole inner connecting tube 9 of flowing through, flows out from 90 degree elbows 4.
Position at the close flange 7 of water interlayer outlet pipe 1 upper surface is provided with a vent 2, the outer surface that is axially perpendicular to water interlayer outlet pipe 1 of vent 2.One end of vent 2 is communicated with externally connected pipe 8, and the other end is threaded and is connected with breathing pipe 3.Breathing pipe 3 one ends connect vent 2, and the other end connects swelling water tank 16.Water vapour in the externally connected pipe 8 of water interlayer outlet pipe 1 enters in the swelling water tank 4 by vent 2 and breathing pipe 3 like this, gradually cooling.
