The material of described openings lead circle is a polyformaldehyde.
On the described exhausr port respirator is installed.
Two circular grooves be located near described piston near the position.
The utility model adopts technique scheme, and piston relies on two openings lead rings at size φ 50 places to lead in moving downward process, and is more stable; The guide material polyformaldehyde is more wear-resisting; Exhaust ports is provided with respirator, can the actv. filtered air, can better prevent dust, and improve the life-span of product; Can also eliminate exhaust noise, realize environment-friendly function.

The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
Structure like the expressed the utility model of Fig. 1, Fig. 2 and Fig. 3; Air brake valve for a kind of construction machinery and equipment; Be connected with stretcher assembly 1 through tappet 2; Described air brake valve comprises valve body 6, piston 4, lower valve assembly 8, on valve body, is provided with admission port 11, air extractor duct 12 and exhausr port 14.
The air brake valve bolt together is realized braking on vehicle chassis.
One, inventive concept of the utility model and creative the analysis:
In order to solve the problem that exists at the described present known technology of this specification sheets background technology part and to overcome its defective, realize the goal of the invention of the steering capability of raising piston, the technical scheme that the utility model is taked is:
To shown in Figure 3, the air brake valve of the construction machinery and equipment that the utility model provided on described piston 4 and surface that described valve body 6 cooperates, is provided with two circular grooves 15, is provided with an openings lead circle 5 in each circular groove 15 like Fig. 1.
Move downward in the process at piston, two openings lead rings at guiding ruler cun φ 50 places lead, and are more stable.
The material of described openings lead circle 5 is a polyformaldehyde.The material of piston guide makes polyformaldehyde into by original aluminium, and is more wear-resisting.
Respirator 16 is installed on the described exhausr port 14.Exhausr port assembling respirator 16 can prevent dust better, improves the life-span of product; Can also eliminate exhaust noise, increase environment-friendly function.
Two circular grooves 15 are located at the position near described piston 4 two ends.Axially increasing the guiding distance, further improve guide effect.
Two, the static position of each parts relation in the utility model:
Valve body 6, lower valve assembly 8, pull back spring 9, spring perch assembly 10 are formed non-brake chamber.
Three, the dynamic position of the utility model relation and principle of work:
1, dynamic position relation:
Step on stretcher assembly 1, apply certain pressure through 2 pairs of balance spring assemblies 3 of tappet, move down thereby promote piston 4, push air inlet spool 13 (lower valve assembly 8) open, the pressurized air that gets into from admission port 11 flows to air extractor duct 12;
2, principle of work
Step on stretcher assembly 1, apply certain pressure through 2 pairs of balance spring assemblies 3 of tappet, move down thereby promote piston 4, push lower valve assembly 8 open, open air inlet spool 13, the pressurized air that gets into from admission port 11 flows to air extractor duct 12;
Loosen pedal, pull back spring 7 backs down piston 4 and upwards promotes, and lower valve assembly 8 returns are closed the passage between admission port 11 and the air extractor duct 12, and the pressurized air of air extractor duct 12 is discharged from exhausr port 14.
Four, the beneficial effect of the invention
The guiding position of piston 4 is two slotted ringes (guide collar 5) guiding at size φ 50 places, and is more stable; The material of piston guide makes polyformaldehyde into by original aluminium, and is more wear-resisting; Respirator 16 is installed on the exhausr port 14.Exhausr port assembling respirator 16 can prevent dust better, improves the life-span of product; Can also eliminate exhaust noise, increase environment-friendly function.
