Six-loop protection valve

Abstract

The invention relates to a six-loop protection valve. The six-loop protection valve comprises an upper valve body, a middle valve body and a lower valve body. The upper valve body is provided with an air inlet, an exhaust port and a pressure regulation part. The middle valve body is provided with an internal air path circulation structure and a valve main body part. The lower valve body is provided with output ports and a pressure sensor output part. The internal air path circulation structure is provided with air pressure cavities, pistons are arranged in the air pressure cavities and provided with spring bases, and the air pressure cavities are provided with holes. The valve main body part is provided with valve main body ports. The pressure sensor output part is provided with pressure sensors. The six-loop protection valve is multifunctional, good in reliability, long in service life, good in real-time performance, good in braking effect and good in independence and safety; the six-loop protection valve is compact in structure, high in intelligence degree and good in reliability and safety, has the loop protection function and saves mounting space in a vehicle, and the service life of the product is prolonged.

Description

technical field [0001] The invention belongs to the technical field of vehicle equipment, and in particular relates to a six-circuit protection valve. Background technique [0002] In vehicle equipment, the output port of the dryer often needs to be equipped with a multi-circuit braking system, so that one of the circuits fails, and the other circuits can still be guaranteed to have a certain safe braking pressure. Most of the existing multi-circuit braking equipment has the problems of single function, poor reliability, short service life, poor real-time performance, poor braking effect, poor independence and poor safety. [0003] The patent number is "ZL200410087954.7", the authorized announcement number is "CN1611403", and the Chinese invention patent named "four-circuit protection valve" discloses a four-circuit protection valve. number of parts and can maintain high strength. The four-circuit protection valve has a valve main body formed of a single body integrated at...
