Abstract
The utility model discloses a ventilation device, especially to a pressure balance control device for an electric locomotive ventilation system, which is characterized by including a casing. An outletwith a protecting net is arranged on the lower end of the casing. At least an inner side surface with a vent, which is inward inclined from top to bottom, is provided on the upper part of the cavityof the casing. The upper edge of the inner side surface is connected with an exhaust cover plate through a rotating shaft, in which the cover of the exhaust cover plate is arranged on the vent. The device is installed on an electric locomotive. When the ventilation device works, an air-flow with a certain pressure overcomes the self-gravity of the exhaust cover plate to make it rotate for a certain angle to the interior of the casing so that the exhaust cover plate is opened. Therefore, the indoor gas is exhausted to the outdoor space through the cavity of the casing and the outlet. If the indoor air pressure of the locomotive is not high enough to overcome the self-gravity of the exhaust cover plate, the vent on the casing is closed by the exhaust cover plate and extraneous dusts can notenter into the indoor space, thus guaranteeing the emission of the cooling air and preventing the backflow of the air-flow and the dusts. The ventilation device has good ventilation effect.
Description
Technical field
The utility model relates to a kind of drafting apparatus, particularly a kind of electric locomotive ventilation system equilibrium of pressure ensuring equipment.
Background technology
Locomotive relies on cooling air that the heat between machinery is taken away in operational process always, thereby guarantees locomotive safe operation in uniform temperature.Cooling air is blown into by the roof cooling fan, and the air outlet at the bottom of the car is discharged again, thereby realizes heat sinking function.If but cooling air can not discharge smoothly, will form difference of pressure between machinery and between the external world, difference of pressure is in case surpass certain value, being opened the door to enter by driver's cab to become uncomfortable or difficult between machinery.Otherwise, if this difference of pressure is very little, or near zero, locomotive drives air flows and the face of land dust that produces may will enter between machinery by ventilation inlet and driver's cab in operational process so, dust covers the equipment of the inside, and the time one is long, will reduce the radiating effect of each parts greatly, parts are out of order easily, influence locomotive and normally move.
Summary of the invention
The purpose of this utility model provides that a kind of fanning effect is good, discharging cooling wind smoothly, can guarantee that certain pressure is arranged in the locomotive all the time, prevent to produce the electric locomotive ventilation system equilibrium of pressure ensuring equipment that the outer dirt thing of car pollutes problem into the car, overcome the deficiencies in the prior art.
Electric locomotive ventilation system equilibrium of pressure ensuring equipment of the present utility model, it is characterized in that: comprise casing 3, the lower end of casing 3 is the outlet of band protecting wire net 7, the inner chamber top of casing 3 has the medial surface of an intilted from top to bottom band vent 8 at least, and this medial surface top is connected with the exhaust cover plate 4 that covers on vent 8 by rotating shaft.
Electric locomotive ventilation system equilibrium of pressure ensuring equipment of the present utility model is provided with packing seal 5 between the periphery of wherein said exhaust cover plate 4 and vent 8.
Electric locomotive ventilation system equilibrium of pressure ensuring equipment of the present utility model, the top of wherein said casing 3 is provided with detouchable cover plate 1, and the outer periphery of casing 3 is connected to adapter plate 6.
Electric locomotive ventilation system equilibrium of pressure ensuring equipment of the present utility model, during installation casing is fixed in locomotive underframe place or other position, the outlet of band protecting wire net is communicated with locomotive is outdoor, the air-flow that has certain pressure in drafting apparatus when work locomotive overcome exhaust cover plate 4 from gravity it is turned an angle to reach purpose of opening, guarantee that indoor gas is outdoor through cabinets cavity and outlet discharge, as the locomotive room pressure less be not enough to overcome the exhaust cover plate when the gravity, vent on the casing is deflated cover closure, extraneous dirt thing can't inlet chamber in, promptly guaranteed the discharging of cooling air, solved the problem that air-flow and dirt thing flow backwards again, fanning effect is good, integral structure is simple, and is easy for installation, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1: 3 is casing, can adopt metal sheet to make, and its underpart is a rectangular shape, and top is the truncated rectangular pyramids shape that links to each other with the bottom, and the medial surface of casing 3 is sloped inwardly from top to bottom.The lower port place of casing 3 is welded with flange and by bolt protecting wire net 7 is installed.Opening is left in the top of casing 3, is connected with cover plate 1 at the opening part screw.Be provided with vent 8 on the upper side of casing 3, the place is connected with exhaust cover plate 4 by rotating shaft 2 in the top of vent 8, is pressed against vent 8 places by the deadweight of exhaust cover plate 4 and makes its sealing.Be provided with packing seal 5 between the periphery of vent 8 and exhaust cover plate 4, packing seal 5 can be located at the periphery that is positioned at vent 8 on exhaust cover plate 4 or the casing 3.Be welded with adapter plate 6 in the outside of casing 3.
By adapter plate 6 this device is installed in locomotive below vehicle frame or place, floor, casing 3 lower port are communicated with outdoor, the air-flow that has certain pressure in drafting apparatus when work locomotive overcome exhaust cover plate 4 from gravity it is turned an angle in casing to reach purpose of opening, guarantee that indoor gas is outdoor through casing 3 inner chambers and outlet discharge, as the locomotive room pressure less be not enough to overcome exhaust cover plate 4 when the gravity, vent 8 on the casing 3 is deflated cover plate 4 sealings, extraneous dirt thing can't inlet chamber in, promptly guaranteed the discharging of cooling air, solve the problem that air-flow and dirt thing flow backwards again, had fanning effect preferably.
