Description of the invention (1) The present invention is a method of applying a forged shape to the seat, and applies the forging method to forge the seat into a water seat first. Second, the valve seat, the limit seat and the outlet seat are welded to form the left and right bodies, respectively. = ^ = The center through hole for forging can be formed—and formed, # to reduce material waste and shorten processing time; further, use ball valve seats And the right and left sealing rings of the limit seat, provide direct pressure ball valve arc surface when leakage is critical, to prevent leakage, to prevent disasters, when there is no liquid or gas in the pipeline, a repair, Those who use the safety benefits. Most of the metal bases that are connected to I are made by casting. Because of the casting, the left and right bodies can be integrally formed, and most of the initial embryo has been formed inside and outside. Partial processing and drilling can complete the ordinary seat; only, in the casting molding, air bubbles are easily generated in the material. In order to reduce the sand holes generated by the air bubbles on the surface, it is necessary to produce the original embryo. Thicken it, and then process the primordial embryo inside and outside to the required thickness $, to reduce the generation of sand holes. Compared with the material to be removed, it is a large, good cost, and the sand holes cannot be completely avoided. The rate is always high = down. If the defective product flows into the market, it often causes leakage. When the gas is 2 or repaired, the fire caused by electric welding will be unavoidable, and the disaster caused by it will be seen from time to time. Due to the aforementioned defects in the casting, the industry is attempting to forge the shape of the seat to eliminate the defects of the sand holes. 1 is 2 Please refer to the first figure: Forging the shape for the industry The produced ^ = embryo, in order to achieve the purpose of one-piece molding, the left and right main bodies A1 and A2 are forged with bedroom forging technology. Due to the limitation of the molding mold after molding, it can be smoothly page 5 477720

V. Description of the invention (2) To be opened properly, the vertical edges of Al and A2 must be formed in the mold, and the necessary A13 must be formed in the mold at the same time. The internal basis such as the left and right bodies of Al and A2 is false. The weight of the material used for this molding will cause complex processing and even the disadvantages of the molding of the material. However, due to the high material, users should look forward to it. Fear is a major regret. When there is further, the habitual ball valve seat body will inevitably age, and a gasket used to control the dangerous gas' liquid will be produced. Due to aging, there is no longer an unexpected danger. How to stop the line of defense? 'And seize the opportunity to seek another priority for improvement. In view of the above-mentioned lack of research, the main purpose of the present invention has finally been developed. The left and right bodies of the composition are respectively forged into a water inlet seat and a correction provided with a withdrawal angle. Form a withdrawal die slope A 11-^ r ^ r ^ rAl through-holes Al2, A22 and the right body Al, A2 of the ball, which should be provided in the shape of the original embryo and the seat itself, and processed. If it is emptied, the demand will inevitably increase, and it will be inconvenient and costly in processing procedures. Such forging, when it can solve the high cost and processing cost, is relatively 'not able to make consumers happy to improve their manufacturing methods. When it is used for a long time, its internal assembly leaks, and like some ball valve transportation control, and once the ball valve achieves the effect of leak prevention, it is inevitable that the ball valve seat body is added to the emergency, it is the failure of the ball valve seat body. The inventor has filed an invention patent based on the missing age. The application is to provide an application that separates the complete ball valve by the appropriate position of the neck. The valve seat, a limit seat, a center right body, A21, and there is no single room. In addition to the shape, due to the working hours, the casting price is extremely useful. In fact, the gasket seat is a temporary step that will occur in the seat and is concentrated. Among them, the seat and the water seat directly 477720 ____ Case No. 87119943 V.
