Abstract
The utility model relates to a remote-distance sectional type vacuum pipeline which comprises a first elbow connected with an online sewage tank and a second elbow connected with a squatting pan. A plurality of sections of straight pipes are connected between the first elbow and the second elbow. The remote-distance sectional type vacuum pipeline is characterized in that the straight pipes are respectively connected with the first elbow and the second elbow through rubber pipes, the rubber pipes are respectively fixed with the first elbow, the second elbow and the straight pipes through hoops, an expansion pipe connector is arranged at one end of each straight pipe, the ends of the adjacent straight pipes are inserted into the expansion pipe connector, sealing rings are arranged between the straight pipes and the expansion pipe connectors, pipe clamps are arranged out the expansion pipe connectors and the straight pipes to enable the expansion pipe connectors and the straight pipes to be fixed, and stoppage removing ports are formed in the connection positions between two adjacent straight pipes. The remote-distance sectional type vacuum pipeline is reliable in sealing performance. The sectional pipeline is installed in an insertion connection mode so as to be convenient to install and large in adjusting allowance. The stoppage removing ports are formed in the connection positions between the straight pipes, so that simple stoppage can be directly dredged through the stoppage removing ports without dismounting the pipeline.
Description
Technical field
The utility model relates to a kind of remote staged formula vacuum line, and is especially a kind of for connecting closet in the train toilet system and the vacuum line of dirt box.
Background technology
At present the feces collecting system major part on train is by setting up vacuum system, utilize pressure reduction that dirt is transferred in dirt box from closet, and to be dirt be transported to transmission path in dirt box from closet to vacuum line.Should guarantee dirt pipeline leak tightness for dirt pipeline system complicated under the car body labyrinth, need simultaneously for convenience detach.Existing vacuum line adopts flange form or screw-type adapting pipe mostly, and fitting allowance is little, the mounting or dismounting trouble.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of remote staged formula vacuum line is provided, and assembling is simple, and is low to space requirement, can be directly by the dredging of pass blocking mouth without detaching pipelines.
According to the technical scheme that the utility model provides, a kind of remote staged formula vacuum line comprises be used to the first bend pipe that connects online dirt box and the second bend pipe that is connected connecting squatting pan, connects the multistage straight tube between the first bend pipe and the second bend pipe; Feature is: described straight tube and the first bend pipe be connected bend pipe and be connected by sebific duct respectively, sebific duct and the first bend pipe, the second bend pipe and straight tube are fixed by the larynx hoop respectively; One end of described straight tube arranges expanded tube joint, and insert in expanded tube joint the end of adjacent straight tube, between straight tube and expanded tube joint, seal ring is set, and is fixed in expanded tube joint and straight tube outer setting pipe clamp.
In the junction of two adjacent straight tubes, the pass blocking mouth is set, on the pass blocking mouth, plug is set.
The degree of depth that described straight tube inserts expanded tube joint is 30～80mm.
At described the first sheathed bend pipe protective case in the bend pipe outside.
Remote staged formula vacuum line sealing property described in the utility model is reliable, and the segmentation pipeline is installed with inserting mode, and adjusting surplus easy for installation is large; Establish the pass blocking mouth in the junction of straight tube and straight tube, for simple obstruction not detaching pipelines directly dredge from the pass blocking mouth.

The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 6: as described in remote staged formula vacuum line comprise the first bend pipe 1, the second bend pipe 2, straight tube 3, sebific duct 4, larynx hoop 5, expanded tube joint 6, seal ring 7, pipe clamp 8, plug 9, bend pipe protective case 10 etc.
As shown in Figure 1 and Figure 2, the utility model comprises be used between the first bend pipe 1 that connects online dirt box and the second bend pipe 2, the first bend pipes 1 that are connected connecting squatting pan and the second bend pipe 2 and connects multistage straight tube 3 according to the vehicle body space situation;
As Fig. 4, shown in Figure 6, described straight tube 3 and the first bend pipe 1 be connected bend pipe 2 and be connected by sebific duct 4 respectively, sebific duct 4 and the first bend pipe 1, the second bend pipe 2 and straight tube 3 are fixing by larynx hoop 5 respectively;
As Fig. 3, shown in Figure 5, an end of described straight tube 3 arranges expanded tube joint 6, and insert in expanded tube joint 6 end of adjacent straight tube 3, between straight tube 3 and expanded tube joint 6, seal ring 7 is set, to realize sealing; And be fixed in expanded tube joint 6 and straight tube 3 outer setting pipe clamps 8;
As Fig. 1, shown in Figure 3, in the junction of two adjacent straight tubes 3, the pass blocking mouth is set, plug 9 is set on the pass blocking mouth, for most blockage problem, can directly dredge by the pass blocking mouth without detaching pipelines;
As shown in Figure 5, the degree of depth that described straight tube 3 inserts expanded tube joint 6 is 30～80mm, and fitting allowance is larger;
As shown in Figure 2, at described the first bend pipe 1 sheathed bend pipe protective case 10 in the outside.
Remote staged formula vacuum line pressure maintaining performance described in the utility model is good, and pipeline system is under-50kPa, and after 30 minutes, pressure rise is less than 5kPa; And adopt the mode of directly pegging graft between adjacent straight tube, assembling is simple, and is low to space requirement, can peg graft according to the vehicle body space multistage.
