Abstract

The present invention relates to a kind of manufacturing method for ball-shape seal ring in ball valve which directly employs stainless steel as the material of ball-shape seal ring for its high operability and ductility. The method is first cutting the stainless steel pipe to suitable size by punch press; then, employing a shuttle-shape forming mold and a ball-shape forming mold for continuous pressing by hydraulic press machine to press the two pipe ends of stainless steel pipe to form a hollow sphere having connected circular holes at both ends so as to complete a ball-shape seal ring. The manufacturing method provides the advantages by reducing the weight, the cost and simplifying the manufacturing processes and reducing the rejection rate of product; the produced ball-shape seal ring is characterized in having higher density for high pressure durability.

Description of the invention (丨) The present invention is a kind of "manufacturing method of spherical pair ring in spheres (2)", which is mainly to provide a box tube with good processability and high ductility. It is a spherical sealing material. It is a method of manufacturing a spherical cymbal ring by using two forming dies I «tubes directly and combined together. Due to the drastic social and economic changes today, the wide range of streets in the country ’s industry has also been continuously raised [so that the quality of the product itself can be improved, and how to reduce the achievements of manufacturing; we wait for our improvements, such as-commonly used u spherical 8, The ritual itself has a certain level of quality and efficacy. It is also an obsession in the market. Few people will pay attention to the spherical sealing ring inside, but the good effect of the spherical sealing ring inside is a direct reflection. !! The quality between the spheres is 1 function, and the sphere is a consumable, but the soil is damaged due to the sphere's flank ring «It must be replaced by the sphere I and the sphere II, so how to reduce the manufacturing cost of the sphere dance ring and make it different The quality is really-to improve the new shooting place 4, but the existing spherical R inner spherical shooting ring manufacturing method, "for the M-front manufacturing method, not only the high cost of the manufacturing process is more prosperous. Pick up! The manufacturing method of the spherical seal ring inside the ball is roughly as shown in the first figure. The manufacturing method of the spherical seal ring inside the whole ball is as follows: It is first made or removed by using the Shasha front | 4 the shape of the spherical sealing ring, and then use the lathe to make the spherical sealing ring hybrid car out of its shape and inner hole, and then II surface, and the inner hole polishing, and finally ... The finished product must be processed through a process of forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, forming, cutting, or cutting. Therefore, the following method may be produced in the forming method used in the production process: 1 · In the preparation process, it is impossible to accurately grasp the manufacturing variables, Therefore, the bad performance encountered during molding is high and the waste material is wasted. In addition, the manufacturing cost is changed from the paper standard to the Chinese National Standard (CNS) A4 specification (210X297). 2 · (Please read the notes on the back before filling in this (Page) Ordered by the Central Bureau of Probability of the Ministry of Economic Affairs β: Industrial and consumer cooperation Du printed equipment A7 404862 _ϋ1 V. Description of the invention (2). High 0 2 · Because of how far the process must be in the manufacturing method, not only the manufacturing process is prosperous, Moreover, each procedure must be completed by a specialized technical street and machinery, because This causes a lack of work efficiency. 3. Because the original Zhao used in 1 is made by the original method, the density of the present ceremony is low. If other procedures are not strict, the inertness of poor waterproofness is likely to occur. For example, "The manufacturing method used in the I was lost, this shot was made by a man with a lot of thought, and I have been engaged in the production and development of the spherical interphase 8 industry for many years. Eventually, a person who invented a "method of manufacturing a spherical inner ring with a spherical shape (2)" was invented. The main purpose of the present invention is to directly use non- «tube as a ball material, using digital molds. With continuous processing, the non-I surface tube is directly formed into a spherical sealing ring, which can be processed in multiple passes and can reduce the finished product. It can reduce the cost, save time, improve work efficiency, and get better water resistance. ^ 1 '^^ 1 n_l' -n ^^ 1 n ^^ 1 i ^ i >.-(Please read the note on the back before filling this page) ___ -------- —— The present invention is a stunned way on the road.

As described in item 1 of the patent country m-a method for manufacturing a spherical inner ring (2), the shuttle forming mold is composed of i and the lower forming mold, each of which is designed as a -half shuttle Shape | 4 inner four molds, the li and rule U errors of the two molds cooperating with each other are slow and accurate [to make it not supply tube and ink to be-light clear shuttle ball β, and then reuse-ball forming mold cross shuttle shape Ball sauce |. Synthesizes a smooth figure ball doll. Its spherical forming mold is guaranteed by an upper and lower shaping mold. Each of them is designed as a concave mold in a half ball. The ball ft and the error if, and The S ball ceremony is combined, and one of the shuttle ball ceremony is placed in the lower plastic mold, and then the other opening pen of the upper I and 11 shuttle ball ceremony is forced to form a shuttle ball ceremony I The ball is the same as the ball sauce, and the openings at the ends of the stern tube "formed into a spheroid" are exposed. Because it is formed into a sprocket, choose W tube first! The shrinkage rate of the supply pipe slows down, and the large-scale treatment at the countersink has greatly eliminated the stress of the supply pipe itself, and the unused tube * 1 itself is a good processability, high density, The high ductility of ftf, the supply pipe itself can withstand the stress of its own part, so when the ball forming mold i shuttle shuttle $ ball into I as the tooth ball sauce paper size, use China National Standard (CNS) person 4 specifications (2 丨 〇 × «7mm and Qiyi (please read the note on the back before filling in this page), 1T. Printed by the Shell Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 404862 Λ8 B8 C8 D8 The range will not leave the number if in the picture hole, but it can be made! -Smooth with two interlinked Lanli hollow picture spheres. (Please read the precautions on the back before filling this page; > Central Ministry of Economic Affairs Standards Bureau's consumer cooperatives print this paper in the size of China (CNS M4 specification (210X297 mm)
