Description of the Invention (彳) The present invention relates to a system of valve seals used in various applications such as industrial processes, etc. The system is provided to produce seals in the stems of such valves, and therefore Controls include the leakage and escape of potentially toxic fluids into the environment ^ Gate valves, ball valves and control valves are the most commonly used in industrial processes, such as those used to obtain pulp and paper in refineries, For its chemical process, these valves must comply with air pollution emission regulations, such as the Clean Air Act of USA ·, the German Environmental Pollution Regulations in Europe (the TA Luft), and others, California, USA It is required that the escape in such valves as above must be limited to less than 100, ppmv ,. The gaskets of these valve types as described above sometimes depend on the two types of stress, one is axial, that is, along the valve stem axis, and the other is radial, which is axial and Vertically, this results in the gaskets of these valves being able to generate such stresses by deformation, and thus achieving an optimally efficient seal to maintain fluid leakage values below the industry acceptable standard. Many gaskets in the existing market have some disadvantages in their sealing function, some of which can be not homogeneous as described above. The above fact is mostly due to the fact that the gasket is made of a single element, which is actually used. These stresses are transmitted on them, and these forces are different from those along the gasket, thus causing imperfect deformation of the conductive seal and causing fluid to leak through the valve. Another problem is that the well-known pads show that due to the excessive height, the conduction of stresses such as T is not the same in all areas of the pad. If the bending problem occurs in the center / position, it will become convex, and thus produce Sealing problems 0 -5- 541407 V. Description of the invention (2 According to the present invention, the applicant's valve sealing gasket system 'and features A / _ have developed legal specifications that can overcome the above-mentioned shortcomings, and achieve appropriate, Control of 100 when the volume of H is released. Volatile products of w are released to the atmosphere. One of the purposes of the present invention is to provide a valve-lined lining system that meets the requirements of the standard. The purpose is to provide an effective 冋 level of pressure resistance, chemical resistance, one of the working resistance 阙 sealed lining system. / 度 阻抗 阻抗 resistance and its own work: hair: another purpose is to provide an effective The axial and radial stresses are both room temperature and high temperature, and the condition of a valve's operating cycle is maintained, and the valve sealing gasket system is maintained-the seal of the uniform sentence. Figure 1 shows in the schematic description -valve -A cross-sectional view of the upper part, the position of the liner is also due to its depiction of the stress pattern in Figure 2. The stress seal is conducted to achieve the best seal in the valve. Figure 3 depicts a complete valve Sectional view, the position of the gasket is also drawn in it.

Now, with reference to the above figures in detail, Illustrate the present invention, and use the reference numbers in the above-mentioned figures, figure i, to show the upper part of the valve, among which the following 4 parts are marked as: _ valve stem ⑴, a filling box ⑺, multiple Gasket (3), liner box, carbon or metal separator 卩 "graphite or carbon threading ring (6), flexible and flexible graphite ring ⑺, bolt or fastener ⑻, nut (9) and flange ( (Flange) (1〇). The purpose of Figure 1 is to show the position of the gasket when these elements (6) and (7) form a gasket against the wall of the valve stem (1) and the gasket box (4), In order to prevent the fluid from flowing from the inside to the outside of the valve, it passes through the space between the valve stem (1) wall and the liner box (4), in which the liners are compressed by the pressure generated by the filling container (2) It is subjected to the tightening pressure caused by the flange (flange) (10), multiple bolts (8) and nuts (9) in this order. As mentioned above, the stresses that should be provided to the pads are axial and radial. As shown in Figure 2, (π) is the radial stress and (12) is the axial stress. It has the dual ability to maintain the seal. In order to show the composition of these parts of a valve and especially its position and the operation of these gaskets, the components or parts shown in the above figure are further shown in Figure 3 as: valve wheel (13), multiple gaskets ( 14), the valve cover or upper part (15), the valve body (16) and the connection between the body / cover (17). Figure 4 shows an example of a variety of pads in the existing market. The pad consists of multiple paper sizes that comply with the Chinese National Standard (CNS) A4 (210 X 297 mm). 5. Description of the invention (4, composed of There is a ring-to-ring structure—the structure is similar to the flat top and bottom two. This type of lining has some disadvantages as described above, especially the gasket ring, and (8) the axial and radial stress Low impedance. According to the present invention, the liner system has been developed in different embodiments to include multiple rings composed of different material combinations. A plurality of pre-formed ring groups that make up the liner system are provided to the bar. The joint itch between the main body and the outer cover depends on the type and grade of the valve. Generally speaking, the system depends on the depth of the envelope box. It includes 3 to 8 rings, a metal or non-metal spacer to fill it. The space in it. In the specific embodiment of the present invention, the cross-sectional view of the cymbal pad system includes a combination of 5 rings, which are:-the first end ring ring, 3 middle ring ring ㈣'⑼ and (22), and the second end ring (23), these rings form the system and perform different functions. According to the "Achieved, multiple internal radial forces are generated, which are the forces on the surface of the valve stem and the outside forces on the wall of the envelope box, resulting in a very effective sealing function. As the culvert box ( 2) The compressive force applied to the first end ring (19) is transmitted to the first central ring (20), and then to the second end ring (23). As can be seen in Fig. 5, the gasket of the present invention is formed. Each ring of the system has a different structure. The first end ring (19), which bears the pressure from the culvert (2), has a flat outer surface (24). The same-ring ring is formed with a given value. — Angle lower part (25); the second ring of the 5 ring group, corresponding to the first central ring (20) has its upper part (26) and an angle lower part (27) with a given value; In this way, the ring 21 also has its upper part (28) and the lower part (29) at an angle; the ring (22) also has its upper part (30) and gives 541407 A7 __B7 V. Invention Note that the fixed value (5) forms an angle at the lower part (31), and finally the second end ring (23) has an angle with the value given by 疋The upper part (32) and its lower part (33) are flat and a ring on the edge of the envelope box. The angle formed by the distant ring is to guide the radial and axial forces generated in the liner group. To some extent it contributes to a more effective seal. In order to simplify the description of the assembly of the ring system, it can be considered as the upper and lower parts of most of these rings, which are at or above their bifurcations. Or a lower angle constitutes a πνπ shape, and therefore the lower end of the ring (19) has the " V " open) structure connected to the upper end of the "V" -shaped structure (26) , Which overlap each other (25)-(26), the same happens to the lower end (27) and the upper end (28); however, starting from the lower end (29), the "V" system is the end (30) Overlapping inverted "v" shapes (29)-(30), the same relationship of this structure is also seen at the ends (31) _ (32), thus achieving a very efficient assembly that forms one of all the rings of the system. As can be seen in Figures 5 to 10, the central ring (21) or (35) has a double, v "shape, which is normal and the other is an inverted" V "shape, and in addition to the axial force, it is conducting There is a dual role in radial force (by having a double sealing point structure, and thus having to concentrate the forces running from the end of the pad) and the arrangement of the pads in the reversible area, which allows the The pad operation efficiency is optimized to ensure a better sealing ability. On the other hand, since the end rings (19) and (23) perform different functions from the central rings (20), (21), and (22), their The first ring (9) is to directly bear the pressure from the culvert, while the last ring (5) of the 5 ring is to maintain the pressure of the culvert, which is transmitted through the ring (20), (21 ) And (22) are connected and sealed by one end and the other end abutting the end of the culvert box. These rings (19) and -9- This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) 541407 A7 V. Description of the invention (6) " '~~ --- = 3). Or make it rougher than the central ring (20) to (22), the $ ::: ί can be used to guide these stresses into a radial force to complete the sealing function in an effective way towards the valve stem. As mentioned above, the properties of the materials constituting the rings It is considered as a significant feature of the invention. These rings are made of different materials, so the end mounts (19) and (23) are based on brocade alloys embedded with elastic and bendable petrochemicals. Steel is made of '俾 for high temperature and extreme rotten name', and the central rings (20), (22) and (22) are made of elastic and bendable graphite with the following structural characteristics of 5 rings. Multiple end loops: Anglo-nickel superalloy composed of graphite flexible strands embedded with elasticity and coated with Barium Molybdate and zinc as a base corrosion inhibitor (Record-based superalloy incOnel) made of steel threading. A plurality of central rings with elastic and bendable graphite (made). Ends% (19) and (23) ·· One of the ends is designed "V", the shape is to maintain the moment, so that the compression force transmitted in the flexible and flexible graphite ring will be deformed to achieve a dense lower part of the seal. Graphite rings. end.卩 Central rings (20) and (22): When compressive force is applied, the V-shaped ends of these rings are pressed on one side toward the surface of the valve stem, and the other side is pressed on the envelope box facing the valve To form a seal. This same ring in turn transmits the necessary force through the outer lower part of the "V" shape to cause the ring (2 丨) to deform. In this deformation, the segment is a pair of "V" shapes, one of which is normal and the other The "V" -shaped structure is opened in the opposite direction of the applied pressure when a pressure is applied in the work provided by the fluid to be sealed, and it can also be implemented. Seal function. -10- This paper size is applicable to China Standard (CNS) A4 specification (⑽x torn public director) 541407 V. Description of the invention (7, one central inner ring · One for each group is applied, such pads are as described above Used to obtain double sealing effect towards one of the valve stem and the valve cover box, these valves can be widely used in all industrial processes that require an active process control. Gate valves, ball valves and control valves reduce the release to the atmosphere. Volatile organic constituents. The voc of volatile organic compounds is prevented because the value has been controlled to less than 10 parts per million. By compressing these pads, the first pad conducts force to the second The pads are in this way oriented toward the last one. The upper part of the second pad, due to the force from the first pad, is open at its part to run the radial pressure toward the valve stem and the envelope box. The second pad conducts the force toward the upper part of the third pad to generate radial stress, but the lower part of the third pad performs two roles, the conduction of the radial stress and the force transmitted to the fourth pad, and the transmission through the connection To the last or The fifth pad generates radial stress at its lower portion. The difference from the previous pad is that it is a single element. When there is a degree of tolerance, it cannot conduct the radial force properly and tends to deform so as to cause An imperfect seal. These materials are important: graphite is used for self-lubrication, and its friction coefficient is low. The hardness of these gaskets is also important depending on their position from one to five and the upper and lower parts to play different roles. The first pad and the fifth pad are kept compressed due to their stiffness. If all pads are made of graphite, such as multiple central pads, the pads will be loose and will cause a spring effect. It is used to support movement.
