3 Technical requirements

3.1 Valve Assembly shall be prescribed by the procedures approved products manufacturing drawings and technical documents, and comply with the requirements of the standard. 3.2 valve seat and the oil should be used GCr15 high carbon chromium bearing steel GB/T 18254-2002 prescribed. The valve can also be 18Cr2Ni4WA use of low-carbon alloy steel GB/T 3077-1999 stipulated. In art or in accordance with procedures prescribed by the theory Under license over the situation, the oil and the oil valve seat to allow the use of other brands of steel manufacturing. 3.3 valve seat and the oil should be subjected to heat treatment (low-carbon alloy steel of the oil valve need cold treatment), so that the size of insurance Remained stable microstructure shall comply with JB/T 9730's. If the materials used in addition to the provisions of JB/T 9730, then its microstructure Press Provisions of the relevant technical documents. 3.4 adopts GCr15 high carbon chromium bearing steel surface of the oil and the oil valve seat are not permitted burns, the oil valve seat hardness 60HRC ~ 64HRC, the oil valve hardness of 60HRC ~ 63HRC. 3.5 using the oil valve 18Cr2Ni4WA low carbon alloy structural steel should be carburizing or carbonitriding quenching, effective case depth It is 0.25mm ~ 0.45mm, the surface hardness of 720HV10 ~ 820HV10. 3.6 valve seat and the oil shall JB/T 9736 provisions were magnetic particle inspection, no cracks. Allows the use by the relevant technical documents Other testing method specified. The main shape and position tolerances of 3.7 and the oil valve seat (refers to the first mating requirements) specified in Table 1. ......
