Abstract
The utility model relates to an automatic unloading valve for an automobile air compressor, which comprises a cylinder cover of the automobile air compressor and a valve board, wherein a valve hole is arranged in the cylinder cover and is communicated with an exhaust hole of the valve board and an exhaust hole of the cylinder cover, and an unloading valve is arranged in the valve hole. When pressure in an air storage tank of an automobile reaches rated pressure, the automobile air compressor automatically unloads to be raced. The utility model has safe and reliable use, greatly reduces the consumption of the power of engines of automobiles, reduces the abrasion of every component of the automobile air compressor and increases the service life of the automobile air compressor by two times to three times. The utility model has serial standards and can be widely matched with automobile air compressors in the existing models.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of automatic deloading valve that is applied to automobile air compressor.
Background technique
At present, the mode of exhaust off-load is mostly adopted in the automobile air compressor off-load, and a safety valve promptly is installed on the gas holder of air compressor gas exhaust piping or automobile, and when the air pressure in the gas holder reached rated pressure, unnecessary pressurized air was discharged from safety valve.This structure exists very big drawback, when the air pressure in the gas holder reaches rated pressure, automobile air compressor is still in the running of overburdening, so not only consumed the power of automobile in vain, but also the life-span of air compressor is shortened greatly, for this reason, some unloading valves attempt to solve this drawback, but many because structural design is unreasonable, working life is short, is seldom implemented by producer.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile air compressor automatic deloading valve, reduces the consumption of automobile engine power the working life that can improve air compressor, and is safe and reliable.
The technical solution adopted in the utility model: a kind of automobile air compressor automatic deloading valve, comprise automobile air compressor cylinder cap, valve plate, be provided with valve opening in its cylinder cap, valve opening communicates with valve plate exhaust port and cylinder cap exhaust port, is provided with unloading valve in the valve opening.
Described unloading valve is made of air inlet elbow, last cap nut, locking nut, piston, O type circle, spring, valve stem, its valve stem is arranged in the valve opening, the bottom is arranged in the valve plate exhaust port, and valve stem top connects with piston by locking nut, is sealed by O type circle; Spring is arranged on the valve stem, and the lower end is against on the cylinder cap, and the upper end is against piston base; The air inlet elbow connects with cylinder cap by last cap nut.
The positive beneficial effect that the utility model had:
1. be provided with unloading valve in the valve opening of cylinder cap, automatic deloading in the time of can reaching rated pressure at the pressure in the automobile gas holder, safe and reliable, reduced the wearing and tearing of each parts of automobile air compressor self, make improve 2-3 doubly the working life of automobile air compressor;
2. when pressure was higher than the resistance of spring, piston moves down automatically opened the valve plate exhaust port, and pressurized air is discharged by the cylinder cap exhaust port, and this moment, air compressor was in the idle running unloading condition, greatly reduced the consumption of automobile engine power;
3. simple in structure, reasonable in design, easy to implement, specification seriesization, can be extensively and the automobile air compressor of current version be complementary.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Consult shown in Figure 1, a kind of automobile air compressor automatic deloading valve, be to be provided with a cascade valve opening 101 at cylinder cap 1 middle part of existing automobile air compressor, valve plate exhaust port 201 on the valve plate 2 of valve opening 101 and existing automobile air compressor is concentric and communicate, valve opening 101 communicates with cylinder cap exhaust port 102 simultaneously, and unloading valve 3 is installed in the valve opening 101.
Described unloading valve 3 is made of component such as air inlet elbow 301, last cap nut 302, locking nut 303, piston 304, little O type circle 305, big O type circle 306, spring 307, valve stems 308, the bar portion of its valve stem 308 is arranged in the valve opening 101, the bottom is arranged in the valve plate exhaust port 201, valve stem 308 bar portions connect with piston 304 by locking nut 303, and binding site is by little O type circle 305,306 sealings of big O type circle; Spring 307 is arranged on the bar footpath of valve stem 308, and the lower end is against on the cylinder cap 1, and the upper end is against piston 304 bottoms; Air inlet elbow 301 is by the top of last cap nut 302 close-coupled at cylinder cap 1.
Working principle of the present utility model: under normal pressure, valve stem 308 bottoms are in the valve plate exhaust port 201, and under the effect of spring 307, form sealing states with the valve opening 101 of cylinder cap 1, the pressurized air that air compressor is produced can only discharge in the automobile gas holder: when the pressure in the automobile gas holder reaches rated pressure, the pipeline that gas holder links to each other with air inlet elbow 301 will be by air inlet elbow 301 to the exhaust of the top of piston 304 and form certain pressure, when pressure is higher than the resistance of spring 307, piston 304 moves down automatically opens valve plate exhaust port 201, the pressurized air that air compressor is produced is discharged by cylinder cap exhaust port 102 through valve plate exhaust port 201, and this moment, air compressor was in the idle running unloading condition.
