Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is front view of the present utility model;
Fig. 2 is A-A section-drawing of the present utility model;
Fig. 3 is B-B section-drawing of the present utility model;
Fig. 4 is C-C section-drawing of the present utility model;
Specific embodiment
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
With reference to a kind of large discharge vehicle height control valve shown in Fig. 1 ~ Fig. 4, comprise check valve assembly, quick coupling assembly, swinging mounting assembly, lower house 8, upper shell 16, ceramic valve seat 9, ceramic slider 14, packing seal 11 and gasket seal 13;
Described upper shell 16, swinging mounting assembly and lower house 8 are fastenedly connected by assembling second screw rod 5 and assembling nut 15; Lower house 8 is provided with admission port and exhausr port, and admission port and exhausr port communicate with ceramic valve seat 9, are provided with quick coupling 18 in admission port, is provided with check valve assembly and quick coupling 18 in exhausr port;
Described ceramic slider 14 is pressed on ceramic valve seat 9 by ceramic slider holddown spring 12; Described ceramic valve seat 9 is arranged between lower house 8 and swinging mounting 7;
Swinging mounting assembly is made up of swinging mounting 7, ceramic slider holddown spring 12, pad 6, first screw rod 3, swing arm stage clip 4; Described swing arm stage clip 4 is set on the first screw rod 3, and described first screw rod 3 one end is plugged in swinging mounting 7, and is provided with pad 6 between swing arm stage clip 4 and swinging mounting 7;
Check valve assembly comprises check valve and mends core 19, check valve spring 20, spool plug 21, seal spool bowl 22 and check valve lining 23; Described check valve spring 20 is arranged on check valve and mends between core 19 and spool plug 21; Described seal spool bowl 22 is arranged on outside check valve lining 23.
Further, O type circle 10, packing seal 11 and gasket seal 13 is provided with between described ceramic slider 14 and swinging mounting 7.
Further, dust-proof sheath 2 is equipped with described swinging mounting assembly.
Its action principle is:
L, when stationary vehicle motionless, or when the vibrations of vehicle bridge, operator's compartment are less, less vibrations drive swinging mounting 7 that vibrations are passed to ceramic valve seat 9 and the ceramic slider 14 of valve body assembly by swing arm 1, although this may make admission port B-B place open, but because swinging mounting 7 is in midway location, air inlet/outlet has been closed, and consumption of air is dizzy still to be can be controlled in comparatively in a small amount;
2, when vehicle under steam, Uneven road, cause vehicle bridge and operator's compartment vibrations larger time;
1. when operator's compartment floats downwards, in air bag, existing pressure can not make vehicle bridge and operator's compartment remain on original height, then swinging mounting 7 is driven to rotate by swing arm 1, the rotating signal of vibrations is passed to ceramic valve seat 9 and the ceramic slider 14 of valve body assembly, admission port B-B place is opened, allows pressurized air to enter in air bag.
2. when operator's compartment upwards floats, through swing arm effect, drive swinging mounting 7 upward movement together, due to the effect of check valve assembly, can not air inlet, air gate discharges, air bag is just communicated with the exhausr port C-C place of valve body assembly, starts exhaust: because gaseous tension in air bag reduces, vehicle bridge operator's compartment reduces, initial position got back to by levelling valve, and now its admission port B-B place, exhausr port C-C place close.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong within the scope of the technical solution of the utility model.
