Summary of the invention
The problem that the utility model will solve is: provide a kind of and can prevent automotive wheel locking thereby the high anti-lock brake electromagnetic valve of safety performance.
In order to solve the problems of the technologies described above, the anti-lock brake electromagnetic valve of the utility model comprises valve body; Said valve body is provided with admission port, air extractor duct, following diaphragm chamber and upper diaphragm chamber, is placed with the upper diaphragm pad in the said upper diaphragm chamber successively, goes up elastic memberance and upper diaphragm spring, and the end of said upper diaphragm spring is stamped the upper diaphragm lid; Be placed with down diaphragm pad, following elastic memberance and following diaphragm spring successively in the said diaphragm chamber down; The said end of diaphragm spring down is stamped down the diaphragm lid, and said valve body is provided with magnet coil, and said magnet coil is provided with the electromagnetism expansion link; One side of said magnet coil is provided with electric interfaces; Said upper diaphragm covers and is fixed with the exhaust module, and said exhaust module is provided with expansion link chamber and deflation hole, and said expansion link chamber is corresponding with the position of electromagnetism expansion link.
In order to reduce the sound during residual gas in the discharging valve body; The anti-lock brake electromagnetic valve of the utility model, the top of said exhaust module is provided with silencing cavity, and said silencing cavity links to each other with deflation hole; Be provided with bloop in the said silencing cavity, said bloop passes through rivet on the exhaust module.
For can be firm upper diaphragm lid and following diaphragm lid be fixed on the valve body, avoid valve body gas leakage, the anti-lock brake electromagnetic valve of the utility model, said upper diaphragm lid and following diaphragm cover and are equipped with several bolt of rear end plates.
The beneficial effect that the utility model is obtained is: when (1) needs brake, give signal of magnet coil, this interior following diaphragm spring pressurized contraction of diaphragm chamber at present; Admission port and air extractor duct conducting utilize pressure gas to realize brake, after brake finishes; Admission port and air extractor duct break off, and give magnet coil another one signal then immediately, and the upper diaphragm spring pressurized in the upper diaphragm chamber shrinks; Deflation hole is opened; Pressure gas remaining in the valve body is discharged, thereby prevent the automotive wheel locking, thereby safety performance is high; (2), be provided with bloop in the silencing cavity, on the exhaust module, thereby the deflation hole exhaust time, exhaust sound is little, can not produce noise through rivet for bloop; (3) upper diaphragm lid and following diaphragm cover and are equipped with several bolt of rear end plates, thereby fixed, can avoid valve body gas leakage.
