Abstract
A sealing gasket of vacuum tube transportation is made of rubber and has an elliptical shape which has a size similar with a door frame. The sealing gasket is fixed to the periphery of the door frame and a flange is provided at the contact interface. The utility model is characterized in that: the flange is internally provided with an airway and the edge of the inner circle is provided with a soft edge; the airway is communicated with the atmosphere when the sealing gasket closely clings to the periphery of a carriage door in the line in using for compressing the flange with the atmosphere pressure and insulating the vacuum space of the line from a passenger channel; if air leakage occurs at the flange slightly, secondary sealing is performed for the soft edge thereby overcoming a defect that air leakage easily occurs at the sealing door of traffic passenger channel of vacuum line.
Description
Technical field
The utility model relates to a kind of hermatic door of vacuum pipe traffic, specifically the tightening seal washer that railway carriage contacts in hermatic door and the pipeline.
Background technology
Utilize the vacuum pipe traffic instrument to transport the passenger, it is fast to have speed, energy consumption is low, weatherproof and take up an area of advantages such as few will replace from now on that the sort of energy consumption is big, expense is high, be subjected to the big vehicle of weather effect, still, the seal request of vacuum pipe is very high, especially the contact surface of passenger's hermatic door and railway carriage easily loses heart about the platform pipeline, directly influences the degree of vacuum in the pipeline, and how improving sealing property is the problem that vacuum pipe traffic must solve.
Summary of the invention
In order to overcome the defective that vacuum pipe back seal door and railway carriage contact surface easily lose heart, the utility model provides a kind of packing seal of vacuum pipe traffic, and the sealing pad is provided with flange and soft limit, can reach undismayed requirement.
The utility model solves the technical measures that its technical matters takes, packing seal is made the ellipse of doorframe size with rubber, its cross-sectional plane is " worker " font, upper sideline at " worker " font is provided with flange, with the hemline center drilling of soft limit at " worker " font, pass in the flange, embed with the recess of " worker " font in the groove of doorframe and fixed, the centre hole of packing seal leads to atmosphere, during use, with the packing seal on the doorframe of hermatic door be close to railway carriage doorframe in the pipeline around, because be in vacuum state in the pipeline, the pressure of atmosphere leads in the flange by centre hole, flange is pressed on the body door plane all around, carry out sealing, if it is disappointing that flange has slightly, disappointing place just has the air communication mistake, and at this moment the soft limit of packing seal then can be close to lose heart under bar pressure and locate to carry out secondary seal, such packing seal is to utilize draught head to realize further leak free, thereby reaches the easily disappointing purpose of contact surface that overcomes vacuum pipe traffic hermatic door and body door.
The beneficial effects of the utility model are, and are for the development of vacuum pipe traffic provides a kind of packing seal of hermatic door, simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the packing seal of vacuum pipe traffic;
Fig. 2 is the cross sectional representation of the packing seal of vacuum pipe traffic.
Among the figure, 1, the packing seal body, 2, the base, 3, the top, 4, flange, 5, flange, 6, soft limit, 7, catching groove, 8, pore.
The specific embodiment
In Fig. 1, packing seal body 1 usefulness rubber is made ellipse.
Cross-sectional plane is " worker " word shape in Fig. 2, flange 4 and 5 are established in the top 3 of " worker " font, the edge of justifying in oval attenuation gradually forms soft limit 6, the groove of " worker " becomes catching groove 6, be fixed in the groove of doorframe, center ventilate 8 at the end 2 of " worker " word, pore pass to flange 4 and 5 in intracardiac, pore 8 logical atmosphere.
Claims (2)
1. the packing seal of vacuum pipe traffic, it is oval to make the doorframe size with rubber, be fixed on doorframe around, the contact interface of packing seal and another object is established flange, it is characterized in that: establish pore in the flange, pore leads to atmosphere.
2. the packing seal of vacuum pipe traffic according to claim 1 is characterized in that: justify edge all around in the packing seal and be arranged to soft limit.
