Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further.
1, Placement
At present, the braking system of various car generally all adopts flange connection, compares with former taper pipe thread Placement, and the sealing of flange connection and reliability are all than higher.Therefore, the novel interface employing flange-interface of adjusting valve and pipeline to wind.
2, adjust opening of valves, closing pressure to wind
The existing cracking pressure of adjusting valve to wind is 420Kpa, and utilization for many years facts have proved the Security not influence of this cracking pressure to braking system, also can satisfy storage reservoir in the wind control system filled the wind requirement.Therefore, novel cracking pressure to wind adjustment valve still is defined as 420Kpa.After adjusting filling air-valve and opening of valve to wind, filling air-valve upper pressure air can fluctuate, when closing pressure during less than cracking pressure, can guarantee to fill air-valve can frequently not open and close when pressure air fluctuates, consider the influence of being filled air-valve and valve base sealing area, fill the air-valve closing pressure and be defined as 400KPa.
3, material
Because grey cast iron has good flowability, body shrinks and linear shrinkage is little, shock absorption is good, can reduce the casting defect of air flue in the cast valve during casting.Therefore, novel valve body to wind adjustment valve is selected the grey cast iron casting for use.
Because brass has good flowability, wear-resisting, corrosion resistance, the material of adjusting parts such as valve interior diaphragm nut and valve seat to wind adopts brass material.
Filter screen adopts powdered metallurgical material in the dust filter, and this material has breathability, filter precision height, and characteristics such as good anti-corrosion and heat resistance can improve the cleanliness of pressure air.
Rubber parts adopts matured product or the material on China's brake in sandwich valve and the valve body, can improve usability and the working life of adjusting valve to wind.
4, main structure
Novel to wind adjust valve by fill air-valve portion 2, safety check portion 4, adjust pressure mechanism 1 and dust filter 3 four parts and valve body 5, spring case 6, nut 7 form.
Adjusting pressure mechanism 1 is made up of adjustment screw, adjustment spring, spring seat, set screw nut.
Fill air-valve portion 2 by diaphragm packing ring 2.2, diaphragm 2.3, diaphragm trim ring 2.4, back-up ring 2.6, fill wind sandwich valve 2.8, sandwich valve spring 2.1, diaphragm nut 2.5, valve seat 2.7 and constitute.Be the charging efficiency of assurance sealing and this valve of raising, fill the former needle valve structure of air-valve portion 2 cancellations, diaphragm nut 2.5 is designed to inner-cavity structure, fill wind sandwich valve 2.8 and place in the diaphragm nut 2.5, lean on guiding groove and sandwich valve spring 2.1, back-up ring 2.6 to fix.Valve seat 2.7 with fill wind sandwich valve 2.8 surface of contact annular flange flange and be designed to arc surface (R0.5), and arc surface is designed to the projection on the platform.This design can guarantee sandwich valve and the closely connected function well of valve seat, eliminates and sews phenomenon.According to force analysis, by the cracking pressure of the effective active area of now using lamina membranacea and 420KPa, the rigidity of adjusting spring must design very greatly.Therefore, the assembling pressure of adjusting spring can not directly act on the vent valve, in order to avoid diaphragm is produced destruction.For this reason, the outer rim of diaphragm nut must contact with valve seat planes during assembling, to bear the assembling pressure of adjusting spring.This structure to accuracy of manufacturing require relatively low, thereby enhance productivity.
Set up dust filter 3 at the intake grill place, further improve by adjust the air purity of valve, the life cycle that prolongs this valve to wind.Dust filter is made of dust filter net lid, sealing gasket, liner, dust filter net.
