The specific embodiment
Explain one of most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the dump truck carriage floor heating arrangement comprises the heat tunnel (not shown) and the manual three-way valve 5 that is arranged in the exhaust emission tube road on the base plate that is arranged on compartment 9, and described exhaust emission tube road comprises blwr exhausr port 1, exhaust brake 3, flexible pipe 4, freeing pipe 6 and noise silencer 7 successively.Wherein, manual three-way valve 5 is installed on the exhaust emission tube road, between flexible pipe 4 and freeing pipe 6, induction opening on the manual three-way valve 5 and flexible pipe 4 are communicated with, and air gate and freeing pipe 6 are communicated with, and another air gate on the manual three-way valve 5 and the air inlet pipe of heat tunnel 8 are communicated with.
The concrete structure of manual three-way valve 5 is shown in Fig. 2～4, its main body is a leak free casing, a side of casing is provided with an induction opening and is communicated with by flange 10 with flexible pipe 4, the bottom surface of casing is provided with an air gate and freeing pipe 6 is communicated with, and the air inlet pipe 8 that the another side adjacent with the bottom is provided with another air gate and heat tunnel is communicated with.Intersection in side, two air gate places is provided with a rotating handle 51, and the rotating shaft of handle 51 is provided with video disc 52, and video disc 52 can rotate in casing with the rotation of handle.Be fixed with two nuts 53 on the casing, be equiped with bolt 54 on the handle 51, the position of described nut 53 and bolt 54 is set to: when video disc turn to when blocking in described two air gates any, bolt 54 on the handle can insert in the nut 53 on the casing, thus the fixing position of video disc.As shown in Figure 3, when not needing to heat the bottom, compartment of dumping car, handle 51 is turned to the upright position, and be fastened on the nut 53 on the valve body (casing) with bolt 54, video disc 52 is turned to the upright position thereupon, thereby block the hole that is communicated with air inlet pipe 8, tail gas just from passing through with the hole of freeing pipe 6 connections, is discharged from noise silencer 7.As shown in Figure 4, when needs heat the bottom, compartment of dumping car, handle 51 is turned to level attitude, and be fastened on the nut 53 on the valve body with bolt 54, video disc 52 is turned to level attitude thereupon, thereby blocks the hole that is communicated with freeing pipe 6, and high-temperature tail gas just enters the heat tunnel of body of tipper carriage bottom by air inlet pipe 8, thereby the bottom, compartment is heated, reach the purpose of this utility model.
