Abstract
The present invention relates to a kind of remote staged formula vacuum line, comprising the first bend pipe for connecting online dirt box and the second bend pipe for being connected squatting pan, between the first bend pipe and the second bend pipe, connecting multistage straight tube; Feature is: described straight tube is connected respectively by sebific duct with the first bend pipe and the second bend pipe, and sebific duct and the first bend pipe, the second bend pipe and straight tube are fixed respectively by larynx hoop; One end of described straight tube arranges expanded tube joint, and the end of adjacent straight tube is inserted in expanded tube joint, arranges seal ring, be fixed in expanded tube joint and straight tube outer setting pipe clamp between straight tube and expanded tube joint.Pass blocking mouth is set in the junction of two adjacent straight tubes, pass blocking mouth arranges plug.Remote staged formula vacuum line sealing property of the present invention is reliable, and segmentation pipeline is installed with inserting mode, and adjustment surplus easy for installation is large; Establish pass blocking mouth in the junction of straight tube and straight tube, simple blocking can not detaching pipelines directly be dredged from pass blocking mouth.
Description
Technical field
The present invention relates to a kind of remote staged formula vacuum line, especially a kind of vacuum line for connecting closet on train feces collecting system and dirt box.
Background technology
Feces collecting system major part on current train is by setting up vacuum system, utilizes pressure reduction to be transferred in dirt box by dirt from closet, and vacuum line is dirt is transported in dirt box transmission path from closet.Dirt pipeline leak tightness should be ensured for dirt pipeline system complicated under car body labyrinth, need for convenience detach simultaneously.Existing vacuum line adopts flange form or screw-type adapting pipe mostly, and fitting allowance is little, mounting or dismounting trouble.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of remote staged formula vacuum line, assembling is simple, low to space requirement, can directly be dredged by pass blocking mouth without detaching pipelines.
According to technical scheme provided by the invention, a kind of remote staged formula vacuum line, comprising the first bend pipe for connecting online dirt box and the second bend pipe for being connected squatting pan, connecting multistage straight tube between the first bend pipe and the second bend pipe; Feature is: described straight tube is connected respectively by sebific duct with the first bend pipe and the second bend pipe, and sebific duct and the first bend pipe, the second bend pipe and straight tube are fixed respectively by larynx hoop; One end of described straight tube arranges expanded tube joint, and the end of adjacent straight tube is inserted in expanded tube joint, arranges seal ring, be fixed in expanded tube joint and straight tube outer setting pipe clamp between straight tube and expanded tube joint.
Pass blocking mouth is set in the junction of two adjacent straight tubes, pass blocking mouth arranges plug.
The degree of depth that described straight tube inserts expanded tube joint is 30 ~ 80mm.
Sheathed bend pipe protective case outside described first bend pipe.
Remote staged formula vacuum line sealing property of the present invention is reliable, and segmentation pipeline is installed with inserting mode, and adjustment surplus easy for installation is large; Establish pass blocking mouth in the junction of straight tube and straight tube, simple blocking can not detaching pipelines directly be dredged from pass blocking mouth.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 1 ~ Fig. 6: as described in remote staged formula vacuum line comprise the first bend pipe 1, 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 first bend pipe 1 that the present invention includes for connecting online dirt box connects multistage straight tube 3 with for being connected between the second bend pipe 2, first bend pipe 1 of squatting pan and the second bend pipe 2 according to vehicle body space situation;
As shown in Fig. 4, Fig. 6, described straight tube 3 is connected respectively by sebific duct 4 with the first bend pipe 1 and the second bend pipe 2, and sebific duct 4 and the first bend pipe 1, second bend pipe 2 and straight tube 3 are fixed respectively by larynx hoop 5;
As shown in Fig. 3, Fig. 5, an end of described straight tube 3 arranges expanded tube joint 6, and the end of adjacent straight tube 3 is inserted in expanded tube joint 6, arranges seal ring 7 between straight tube 3 and expanded tube joint 6, to realize sealing; And be fixed in expanded tube joint 6 and straight tube 3 outer setting pipe clamp 7;
As shown in Figure 1, Figure 3, pass blocking mouth is set in the junction of two adjacent straight tubes 3, pass blocking mouth arranges plug 9, for most blockage problem, can directly can be dredged by 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, sheathed bend pipe protective case 10 outside described first bend pipe 1.
Remote staged formula vacuum line pressure maintaining performance of the present invention is good, and pipeline system is under-50kPa, and after 30 minutes, pressure increase is less than 5kPa; And adopt the mode of direct grafting between adjacent straight tube, assembling is simple, low to space requirement, can according to the grafting of vehicle body space multistage.
