The conventional all-welded valve has basically several types as shown in the first figure, · short tube butt welding, flange welding, and the short and flange can be mixed, the full splicing valve is made. The official material (1), and then the perforation (1 a ) of the (2) position of the pipe material (i), and at the position of the assembly ^, the pipe must be first processed (丄b): because (3), Therefore, at least the tube should be shrinked twice, and the ▲ official system should be extended to the position of the ball plug. Therefore, the tube of the extension tube must be made with the ring flange by the extension tube; d can be configured (1), The body's rising yield and the large amount of groundwater in the cold belt of the continent are 'not economical to use the delivery pipe valve. Because the valve is lost, so the foam is used, and the long pipe is insulated and welded (the long pipe in the middle, the valve stem must be prepared) Bushing long pipe (3) Two-end extension pipe long pipe, the extension should be too large, and the limit ball plug 5 M334236 ==, the extension pipe is made of the ring flange (3a), and when all materials are processed, , welding is also a clever problem, because all are scattered materials, even if it is difficult to ensure that it is arranged The process will not shift, and the ball seal ring (: stand: still against the ball plug (5), for this purpose first need to prepare the relevant positioning of each part of the zero: no α jigs are difficult to manufacture and the cost is also very high, Another fixture with a high unit price is assisted in positioning, but at the high temperature of welding "= deformation, so that the accuracy shifts, or the concentricity shifts; and the other 2^ section is still more variable because of the processing process, ", Μ: The quality of the quality can not be separated from the production process depends on luck. It is difficult to improve the yield, quality... Processing = The above description can be learned that the use of all welding f is basically difficult and the accuracy is not good. The cost of the fixture is high, and because it is all-weld, it must be tested by the whole gentleman, Yang ^, ^ ^ tube), but the whole welding is extended with a length of each mother is quite large, it is not easy to test, and based on: Type: All welded valves must be prepared with different fixtures, and the process concentricity of the cost will be ran away, so the concentricity is not good, and it is difficult to standardize the production control of the all-welded valve. Knowing the problems of the structure, how to Producing more ideal and practicality is also a related leader,... The real consumer is eagerly awaiting the goal and direction of the key industry's efforts to develop breakthroughs. Invitations ^ΓThis 'Jian Zuo Ren has been engaged in related products for many years. The manufacturing and development, the experience of the singer, the finalization - the practical design of the original 1 ping plus design and prudent evaluation, 6 M334236 [new content] technical problem to be solved: each of the well-known all-welded valve The status of product output is different. 'Depending on the fixture and experience, but the fixture is expensive and the experience accumulates also costs, so it is difficult to standardize, resulting in difficult to improve yield, and the process will also cause concentric shift, accuracy is not Good, processing is not easy, and in the test process, because all the welding is completed before testing, the product is too large and the test is difficult. The technical feature of solving the problem: providing a valve body structure (1) for improving the all-welded valve, the forming result of each valve body is different for the conventional one, and the welding process is difficult and the related equipment is expensive. The effect is not good enough. The comprehensive re-innovation of the all-welded valve is made to conform to the standardized specifications and production. The valve body includes a valve body, a material member, a spacer, a ball plug and a ball seal ring. The wide body has a gradually expanding open space toward one side, so that the wedge portion of the valve member and the ring flange of the positioning ball sealing ring can be accurately formed, and the valve body is precision facing outward: thread, The fitting body also has a matching wedge portion, and the ring: Du Chao is also precisely threaded. According to this, when the ball plug and the sealing ring are assembled, the position can be adjusted to the sound of the ND and the valve. The sub-pieces are pre-twisted with the upper part of the wedge to the main body part, so that the components can be positioned just before, and when the valve parts and the valve body are fixed, the carcass can be accurately quenched without the fixture. The standardized carcass has not been assembled yet. Tube, the body ::: easy to test the binding can be ensured by misalignment. The effect of the body red control technology: 1. The prior art has undergone considerable pre-processing to prepare the various parts of the M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M M For each different full-welding valve, it is expensive to manufacture the fixtures that are not the same as the welding aids, so that the welding can be accurate and the production is accurate, but the welding process is still variable. If the high temperature causes the material to deform and shift, it will affect To the accuracy and concentricity of the finished product, each time the high temperature position and temperature are different, 'whether the ambient temperature affects' will cause the status of each item to be different' and it is difficult to standardize the production. The 4W Wenliang full welding valve body...-), the valve body is divided into a valve body and a valve member, and the bean valve body and the valve member are respectively provided with a wedge portion and a wedge portion. First pre-combination: This can make the internal clamping position quite accurately, and then the welding of the valve body and the valve member does not require 仏+, but the mouth is auxiliary, and the concentricity and precision of the finished product are quite high. . 2 · The prior art is involved in the order, the degree of M ^ ^ dan / 鄕 ^ Wang 谇 valve, and the mother's welding of the shirt is quite loud, the household ^ ^, must wait until the king's all-welded valve is completely welded ' Only after the test can be carried out, but the soybean meal, the length of the length is longer, and is not conducive to the product...
