Description of the invention (>) (Please read the precautions on the back before filling this page) The material is prone to generate air bubbles. In order to reduce the sand holes generated by the air bubbles on the surface, it is necessary to mold The primordial embryo is thickened, and then the primordial embryo is processed inside and outside to the desired thickness: the thickness of the primordial embryo can reduce the generation of sand holes, which is a waste compared to the material to be removed: & The sand holes cannot be completely avoided, so * The defective rate is always high. If the defective product is left in the market, it often causes leakage. The fire caused by the gas explosion or repair will be unavoidable, and the disasters caused by it will be seen from time to time. Printed by the Consumer Cooperative of the Central Bureau of Standards, Ministry of Economic Affairs due to the lack of the aforementioned ball valve in the sickle manufacturing, the industry is trying to forge the ball valve seat body * K to eliminate the regret of the occurrence of sand holes; it is M, see The first picture shows: the original embryo A produced by the industry using a forged one-piece flanged ball valve. In order to achieve the purpose of integral molding, it is achieved by the M horizontal forging technology. The mold can be opened smoothly, and then the ejection angle must be set in the crossbar, so that the vertical mold edge A 1 is formed at each vertical edge of the embryo, the mold is opened, and the mold is a piece after molding. The flange type ball valve seat body A cannot form the necessary water inlet and outlet holes A2, A3 and the ball valve accommodation chamber A4 at the same time. Therefore, the M-type flange ball seat body A is formed from the original embryo. For the solid state, the inside must be removed according to the shape of the ball valve seat body, such as the dotted line A5 *. Please refer to the second figure to show: Ball valve B positioning A plug C, and an outer screw segment C 1 and the front end are also processed to form a right water stop accommodating groove C 2; and it is located at the bottom end of the ball valve accommodation chamber A4, and a left water stop washer is required to be processed to accommodate Slot A4 1 * Suifi: It must be processed into a very deep bottom, and then processed in that depth • It is conceivable that this paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 4 5 4 0 7 t A7 B7 Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention ㈠) It is quite difficult, obviously the processing is extremely difficult; then K is used to plug the screw segment C outside C, and it is also fitted with a screw fixative lock Into the inner screw section A 3 1 of the water outlet hole A 3 on the right side of the one-piece flanged ball valve seat body A, so that the plug C is water-stopped...... On the arc of the ball valve B; due to the conventional structure ** ....... *, the plug C is indispensable for a one-piece flanged ball valve seat, so the manufacturing and processing are added The cost and time of checking plug C; therefore * Knowing whether one piece of flanged ball valve seat body is sickle or forged, the cost of materials used is extremely , The weight of the lotus in processing will cause inconvenience in processing, and ......... It is also relatively complicated in processing procedures, and it will cause waste of materials; if the satin shape is used to solve the sickle shape, However, due to the high material cost, time-consuming processing, and high relative price, it is a regret that users cannot use it when they are timid by users. When it is necessary to further improve its manufacturing method, it is necessary. However, in view of the foregoing shortcomings, the inventor gathered many years of experience in manufacturing ball valve seat bodies, worked hard, and finally got rid of the general manufacturing method, and developed the present invention, and then filed an application for an invention patent. The main purpose of the present invention is to provide a method for manufacturing a forged one-piece flanged ball valve seat body and its improved structure.
