Description
Affiliated technical field the utility model relates to a kind of drainage car, relates in particular to a kind of seal arrangement that is used for the drainage car telescopic pipe.
Background technique Chinese patent CN201211406Y discloses a kind of so high spray fire-fighting recovery vehicle multi-stage expansion water pipe assembly, its structural feature is: it is three grades of adjustable structures being made up of outer water pipe, flexible water pipe and guide piston, flexible water pipe is housed in outer water pipe, between outer water pipe and the flexible water pipe guide piston is housed, in the flexible water pipe flexible water pipe is housed, between flexible water pipe and the flexible water pipe guide piston is installed; Guide piston is fixedlyed connected with flexible water pipe by two built-in Steel Cable Baffle Rings; The place that is used to install Steel Cable Baffle Ring between guide piston and flexible water pipe all is processed with trapezoidal annular groove; Guide sleeve is housed on outer water pipe, guide sleeve is fixedlyed connected with outer water pipe by flange, surface Machining has the multiple tracks annular groove within it, be respectively applied for two lips combination dust rings are installed, one or more supporting ring and one or more seal ring, this structure is applicable to fire-fighting truck, can effectively water be transported to the scene of a fire, but because guide piston is fixedlyed connected with flexible water pipe by two built-in Steel Cable Baffle Rings, in use, easily make guide piston break away from flexible water pipe, again because guide sleeve is housed on outer water pipe, guide sleeve is fixedlyed connected with outer water pipe by flange, easily there is bigger coaxiality error, influences assembly quality and leakage proof effect, simultaneously, increase materials consumption, in addition, owing on the guide sleeve oil groove is not set, easily cause component wear.
The summary of the invention the purpose of this utility model provides a kind of leakage proof better effects if, the nonabradable seal arrangement that is used for the drainage car telescopic pipe.
For achieving the above object, the utility model is used for the seal arrangement of drainage car telescopic pipe, form by packing holder, charging air inlet, pneumatic tube, switch, gas cylinder, source of the gas and gas-flow closure circle, the gas-flow closure circle is arranged on the packing holder that is installed in the telescopic pipe outer tube, the gas-flow closure circle is provided with charging air inlet, the other end of charging air inlet is connected with switch by pneumatic tube, and the other end of switch is connected with gas cylinder by pneumatic tube, and the other end of gas cylinder is connected with source of the gas by pneumatic tube.
Described gas-flow closure circle cross section is processed into swallow-tail form, in the gas-flow closure circle, is processed with the cavity of energy stored-gas.
In with respect to telescopic pipe, be processed with the groove that the cross section that the gas-flow closure circle can be installed is swallow-tail form on the packing holder of pipe.
After adopting this structure, because the gas-flow closure circle is arranged on the packing holder that is installed in the telescopic pipe outer tube, the gas-flow closure circle is provided with charging air inlet, the other end of charging air inlet is connected with switch by pneumatic tube, the other end of switch is connected with gas cylinder by pneumatic tube, the other end of gas cylinder is connected with source of the gas by pneumatic tube, when telescopic pipe is not flexible, gas in the gas cylinder is through switch, pneumatic tube and charging air inlet are delivered in the gas-flow closure circle and with the one side jack-up of gas-flow closure circle pipe in telescopic pipe, make it closely to contact, thereby reach the leakage proof purpose with the telescopic pipe inner tube outer surface; When telescopic pipe is flexible, bleed off the gas in the gas-flow closure circle, reduced component wear, prolong product working life.
The utility model is described in further detail below in conjunction with drawings and Examples for description of drawings.
Fig. 1 is the main cross-sectional schematic of the utility model seal arrangement of being used for the drainage car telescopic pipe.
Fig. 2 is that cross-sectional schematic is amplified in the part of Fig. 1.
Among the figure: 1. manage 5. cavitys, 6. charging air inlets, 7. pneumatic tubes, 8. switches, 9. gas cylinders, 10. sources of the gas in telescopic pipe outer tube 2. packing holders 3. gas-flow closure circles 4. telescopic pipes.
Embodiment Fig. 1, the utility model shown in Figure 2 are used for the seal arrangement of drainage car telescopic pipe, form by packing holder 2, charging air inlet 6, pneumatic tube 7, switch 8, gas cylinder 9, source of the gas 10 and gas-flow closure circle 3, gas-flow closure circle 3 is arranged on the packing holder 2 that is installed in the telescopic pipe outer tube 1, gas-flow closure circle 3 is provided with charging air inlet 6, the other end of charging air inlet 6 is connected with switch 8 by pneumatic tube 7, the other end of switch 8 is connected with gas cylinder 9 by pneumatic tube 7, and the other end of gas cylinder 9 is connected with source of the gas 10 by pneumatic tube 7; Described gas-flow closure circle 3 cross sections are processed into swallow-tail form, in gas-flow closure circle 3, are processed with the cavity 5 of energy stored-gas; In with respect to telescopic pipe, be processed with the groove that the cross section that gas-flow closure circle 3 can be installed is swallow-tail form on the packing holder 2 of pipe 4.
