RECEIVING OPENING OF JOINT FOR WORKING FLUID AND VALVE WITH THE RECEIVING OPENING

摘要

[PROBLEMS] A receiving opening of a joint for working fluid, the receiving opening having high breaking strength and excellent corrosion resistance, and a valve having the receiving opening are provided. [MEANS FOR SOLVING PROBLEMS] A female screw portion (4) communicating with the inside of a resin cylinder body (9) is fixed to the cylinder body (9) with the female screw portion (4) projecting from the outer surface of the cylinder body (9), or with the female screw portion (4) being positioned outside the outer surface of the cylinder body (9). Receiving openings (1, 2) are formed by insert molding using a resin with a tensile elongation ratio of 50% - 400% and tensile strength of 50 MPa - 200 MPa, and the openings are fixed to the resin cylinder body (9).
