Abstract

The utility model relates to a double-chamber automobile series valve, which belongs to the technical field of automobile components. The double-chamber automobile series valve comprises a pedal plate, an ejector rod, a mounting base, an upper valve body, a lower valve body, a ejector rod seat, a balancing piston and a return spring.

The double-chamber automobile series valve pushes the balancing piston to move downwards through the pedal plate, an upper exhaust valve is closed, and the upper air intake valve is opened, so as to enable the compressed air to be output to a brake pipeline 1; and meanwhile, a relay piston moves downwards under stress, the lower exhaust valve is closed, the air intake valve is opened, and the compressed air is enabled to be output to a brake pipeline 1. When a first loop ceases to be effective, a balancing piston is pushed to be open forcibly, a second loop is enabled to work normally. The ineffectiveness of the second loop produces no influences on the normal work of the first loop, thereby playing a double insurance effect and solving the problem that aeration for an air reservoir can not be performed as a loading line is damaged.

一种双腔汽车串联阀A dual-chamber automotive tandem valve

技术领域：Technical field:

本实用新型涉及一种串联阀，具体涉及一种双腔汽车串联阀，属汽车零部件技术领域。The utility model relates to a tandem valve, in particular to a double-cavity automobile tandem valve, which belongs to the technical field of auto parts.

背景技术：Background technique:

汽车的制动是将汽缸内的压缩空气通过汽车气制动阀输送到前后快放阀，然后再到各个车轮制动机构内而达到汽车制动目的的。目前的汽车多采用单管路断气制动，它的不足之处在于单管路断气制动仅靠一条主管路实现充气和断气制动，当汽车连续制动时，主管路就无法继续向储气筒充气，造成储气筒气压连续下降，而降低制动强度，甚至制动功能消失。也有采用紧急继动阀来实现双管路制动，即一条充气管路，一条制动管路，但当充气管路损坏而无法向储气筒充气，或制动管路漏气、损坏，则起不到双重保险的作用。The brake of the car is to send the compressed air in the cylinder to the front and rear quick-release valves through the car air brake valve, and then to each wheel brake mechanism to achieve the purpose of car braking. Most of the current automobiles use single-pipeline air-cut brakes. Its shortcoming is that the single-pipeline air-break brakes only rely on one main pipe to realize inflation and air-break braking. When the car brakes continuously, the main pipe cannot continue The air cylinder is inflated, causing the air pressure of the air cylinder to drop continuously, reducing the braking strength, and even the braking function disappears. There are also emergency relay valves used to achieve dual-pipeline braking, that is, one inflation pipeline and one brake pipeline. Can not achieve the effect of double insurance.
