Abstract
The utility model relates to a corrugated exhaust pipe with beautiful appearance and good sealing property, belonging to the technical field of exhaust device, which comprises a corrugated pipe whose two ends are fixedly connected with two same flange plates, wherein the corrugated pipe has two layers as an inner pipe and an outer pipe; the inner side of the inner pipe is provided with an air inlet pipe; the intermediate layer between the inner pipe and the outer pipe is provided with an water inlet pipe; the middle part of the corrugated pipe is provided with a corrugated part; the corrugated pipe are provided with solid parts near two ends; the flange plates is provided with holes at the parts corresponding to the intermediate layer of the corrugated pipe for flowing water out and in; the corrugated pipe is fixedly connected with the flange plates via welding; the inner hole of the flange plate is welded with the inner pipe of the corrugated pipe and is a waist-form hole. The corrugated exhaust pipe has reduced material consumption, beautiful appearance and good sealing property.
Description
Technical field
The utility model relates to the venting gas appliance technical field, the exhaust expansion bellows of especially a kind of beautiful shape, good seal performance.
Background technique
The explosion-proof type rubber-tired cart is a modernized large-scale colliery auxiliary conveying equipments, this equipment is many to be power with explosion-proof type diesel type motor, diesel engine is in transportation process, the temperature of institute's combustion gas is higher, generally about 800 ℃, this just brings a lot of difficulty to exhaust gas discharging, also can produce unsafe factor.
Exhaust expansion bellows is no more than 150 ℃ in order to guarantee surface temperature under the coal mine at present, generally adopts double-ply bellows, by cooling water, surface temperature is lower than in the middle of the two-layer bellows, but mostly is complex structure, and sealability is unreliable.
The model utility content
The technical problems to be solved in the utility model is: for shortcoming and the deficiency that solves above-mentioned existence, provide the exhaust expansion bellows of a kind of beautiful shape, good seal performance.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of exhaust expansion bellows, has bellows, the two ends of bellows is fixedly connected with identical flange plate, bellows is the double layer construction with interior pipe and outer tube, interior pipe inboard is an air inlet pipeline, interior pipe is an inlet pipeline with the outer tube mesosphere, the middle part of bellows is a corrugated part, two close end of bellows is an entity portion, offer the hole that is used for water inflow outflow with the corresponding part in the mesosphere of bellows on the flange plate, by the water filling in bellows of the hole on the flange plate, orifice flow from the flange plate of other end goes out then, circulating reaches the effect that reduces temperature, has saved outside connecting pipeline like this, and profile is more neat and artistic.
Further, in order to improve the sealability of exhaust expansion bellows, bellows and flange plate be fixedly connected as welding, the interior pipe of the endoporus place welded bellows of flange plate.
The hole is designed to waist shaped hole, has strengthened the distance of waist shape edge to the flange plate endoporus, makes the sealability of bellows better.
The beneficial effects of the utility model are that exhaust expansion bellows of the present utility model is saved material, beautiful shape, good seal performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is the overall structure right elevation of Fig. 1.
1. corrugated tubes among the figure, 2. flange plate, 3. hole.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, the exhaust expansion bellows of preferred forms shown in Figure 2, has bellows 1, the two ends of bellows 1 is fixedly connected with identical flange plate 2, bellows 1 is the double layer construction of pipe and outer tube in having, interior pipe inboard is an air inlet pipeline, interior pipe is an inlet pipeline with the outer tube mesosphere, the middle part of bellows 1 is a corrugated part, two close end of bellows 1 is an entity portion, offer the hole 3 that is used for water inflow outflow with the corresponding part in the mesosphere of bellows 1 on the flange plate 2, by the hole on the flange plate 23 water filling in bellows 1, flow out in hole from the flange plate 2 of other end 3 then, circulating reaches the effect that reduces temperature, has saved outside connecting pipeline like this, and profile is more neat and artistic.
The welding that is fixedly connected as of bellows 1 and flange plate 2, the interior pipe of the endoporus place welded bellows 1 of flange plate 2, hole 3 is designed to waist shaped hole, has strengthened the distance of waist shape edge to the flange plate endoporus, improves the sealability of exhaust expansion bellows.
When the utility model is implemented, the air inlet pipeline of exhaust expansion bellows is communicated with diesel engine, and inlet pipeline is communicated with cooler bin, and the cooling by cooler bin makes the water circulation use in the bellows 1, make that the surface temperature of bellows 1 can be not too high, strengthened explosion-proof Security.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
