The isolating valve comprises a valve body made of soft magnetic alloy after cold heading, a through hole is formed in the middle of the valve body in the axial direction and serves as a working hole, an oil inlet is formed in one end of the working hole, a metal sealing sheath is fixed outside the oil inlet, a hole is formed in the middle of the sealing sheath, and the middle of the sealing sheath is covered with a first filter screen. By the adoption of the scheme, the valve body is made of the magnetically soft alloy material subjected to cold heading, the hardness of the valve body is improved, meanwhile, the magnetic conductivity of the valve body is guaranteed, the hardness requirement during valve body assembling is met, the valve body is not prone to deformation, metal powder is reduced, and the working environment of the electromagnetic valve is protected; in addition, the metal sealing sheath is arranged outside the oil inlet, so that the strength is high, and the stability is good; and the first filter screen is arranged to prevent impurities from entering the internal working cavity of the electromagnetic valve from the oil inlet.
本发明涉及一种隔离阀及制动系统,包括由软磁合金冷镦后制成的阀体,阀体的中部沿轴向开设有通孔并作为工作孔,工作孔的一端为进油口,进油口外固定有金属密封护套,密封护套的中部开孔并覆盖有第一滤网。采用本方案,阀体使用软磁合金冷镦后的材料制成,提高了阀体的硬度同时保证了阀体的导磁性,以满足阀体装配时的硬度需求,使得阀体不易变形,减少金属粉末的产生,以保护电磁阀的工作环境;此外,在进油口外设置金属密封护套,强度高,稳定性好;设置第一滤网,防止杂质从进油口进入电磁阀的内部工作腔。
