Abstract
The invention relates to a long distance sectioned vacuum pipeline which comprises a first bend used for connecting with an online sewage box and a second bend used for connecting with a squatting pan, wherein a multi-section straight pipe is connected between the first bend and the second bend. The long distance sectioned vacuum pipeline is characterized in that the straight pipe is respectively connected with the first bend and the second bend through a rubber pipe; the rubber pipe, the first bend, the second bend and the straight pipe are respectively fixed through a hose clamp; one end of the straight pipe is provided with a pipe expansion joint; the ends of adjacent straight pipes are inserted into the pipe expansion joint; a sealing ring is arranged between the straight pipe and the pipe expansion joint; a pipe clamp is arranged outside the pipe expansion joint and the straight pipe for fixation; a through blocking opening is formed at the joint of two adjacent straight pipes; and a plug is arranged on the through blocking opening. The long distance sectioned vacuum pipeline is reliable in sealing performance, the sectioned pipeline is arranged in a plugging mode, and the pipeline is convenient to mount and large in adjusting allowance; and moreover, the through blocking opening is formed at the joint of two adjacent straight pipes, and simple blockage can be directly dredged from the through blocking opening without detaching the pipeline.
Description
Technical field
The present invention relates to a kind of remote staged formula vacuum line, especially a kind ofly be used to connect the closet in the train defecate collection system and the vacuum line of dirt box.
Background technology
At present the defecate collection system major part on the train is by setting up vacuum system, utilize pressure reduction that dirt is transferred in the dirt box from closet, and to be dirt be transported to transmission path in the dirt box from closet to vacuum line.The dirt pipeline system complicated down for the car body labyrinth should guarantee dirt pipeline leak tightness, needs for convenience detach simultaneously.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 objective of the invention is to overcome the deficiencies in the prior art, a kind of remote staged formula vacuum line is provided, assembling is simple, and is low to space requirement, can be directly by the logical mediation of blocking up without detaching pipelines.
According to technical scheme provided by the invention, a kind of remote staged formula vacuum line comprises first bend pipe and second bend pipe that is used to be connected squatting pan that are used to connect online dirt box, connects the multistage straight tube between first bend pipe and second bend pipe; Feature is: described straight tube is connected by sebific duct respectively with second bend pipe with first bend pipe, and the sebific duct and first bend pipe, second bend pipe and straight tube are fixed by the larynx hoop respectively; One end of described straight tube is provided with expanded tube joint, and insert in the expanded tube joint end of adjacent straight tube, between straight tube and expanded tube joint seal ring is set, and fixes in expanded tube joint and straight tube outer setting pipe clamp.
In the junction of two adjacent straight tubes logical blocking up is set, on logical blocking up, plug is set.
The degree of depth that described straight tube inserts expanded tube joint is 30～80mm.
At the sheathed bend pipe protective case in described first bend pipe outside.
Remote staged formula vacuum line sealing property of the present invention is reliable, and the segmentation pipeline is installed with inserting mode, and adjusting surplus easy for installation is big; Establish logical blocking up in the junction of straight tube and straight tube, for simple obstruction not detaching pipelines directly from the logical mediation of blocking up.

The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 6: as described in remote staged formula vacuum line comprise 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 present invention includes between first bend pipe 1 that is used to connect online dirt box and second bend pipe, 2, the first bend pipes 1 that are used to be connected squatting pan and second bend pipe 2 and connect multistage straight tube 3 according to the vehicle body space situation;
As Fig. 4, shown in Figure 6, described straight tube 3 is connected by sebific duct 4 respectively with second bend pipe 2 with first bend pipe 1, and sebific duct 4 and first bend pipe 1, 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 is provided with expanded tube joint 6, and insert in the 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 fix in expanded tube joint 6 and straight tube 3 outer setting pipe clamps 7;
As Fig. 1, shown in Figure 3, in the junction of two adjacent straight tubes 3 logical blocking up is set, on logical blocking up, plug 9 is set, for most blockage problem, can directly dredge without detaching pipelines by logical blocking up;
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 bigger;
As shown in Figure 2, at the sheathed bend pipe protective case 10 in described first bend pipe 1 outside.
Remote staged formula vacuum line pressure maintaining performance of the present invention is good, and pipeline system is under-50kPa, and downstream pressure rose less than 5kPa in 30 minutes; And adopt the mode of directly pegging graft between the adjacent straight tube, assembling is simple, and is low to space requirement, can peg graft according to the vehicle body space multistage.
