The of the present utility model structure expressed as Fig. 1; unloader valve for a kind of automobile and construction machinery and equipment brake system; the technical field that belongs to automobile or construction machinery and equipment pressure regulation system delivery air device; after being applied to brake system use unloader valve, the constant air pressure adjustment fender guard of pipeline output rearwards.Described unloader valve comprises unloader valve valve body 8, inlet suction port 19 and air outlet adapter 11.
Concrete specification: EQ153 (JAC) unloader valve interconnects by inlet, outlet screw thread and brake piping, and is fixing on adapter plate by M8 screw thread on the unloader valve valve body 8 in addition.
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 safe application performance of raising car load, the technical scheme that the utility model is taked is:
The unloader valve of automobile provided by the utility model and construction machinery and equipment brake system, described unloader valve is provided with drain tap assembly 14 and regulator, described regulator is established the little assembly 7 of pressure regulation, and the little assembly 7 of described pressure regulation is connected with the spool of drain tap assembly 14; The gas circuit of described air outlet adapter 11 is communicated with described regulator.
Unloader valve is mainly used in automobile or the construction machinery and equipment brake system pressure pipeline, is used for operation pressure in the automatically regulating brake system, and impurity such as the oil under the filter, water can be discharged automatically by unloader valve.
Adopt technique scheme, in whole brake system, unloader valve is set,, help the safe air pressure in the better protection brake system in order to improve the safe application performance of car load; Can satisfy in automobile or the engineering truck brake system, make that air pressure keeps clean in the brake piping, air extractor duct air pressure is unlikely to too high, and system is played pressure limiting, safety guard-safeguard effect.
One-way valve structures:
The regulator structure:
