Description

1 TARIFF Modular gate valve system Technical Area 5 The invention relates to gate valves used for insulation purposes in pipelines. The invention specifically addresses shaft sealing and shaft movement through modular connection equipment. 10 Different valve configurations can be made based on the type and shaft drive connection type. It relates to the sliding valve system that makes this possible. State of the Art Gate valves are used in pipelines in both fully open and fully closed positions, allowing the flow of fluid to increase by 15 degrees. These are pieces of equipment that enable isolation. The slide inside is perpendicular to the fluid. As a result of its action, the fluid path is closed, thus ensuring a leak-proof seal. The fluid passage is ensured by completely opening the fluid path. Gate valves are used in the following situations: industry requirements, user risk definitions, and different fluids to be used. It can be produced in various configurations. 20 The bolt is connected to a shaft and, via teeth located on the shaft, When the spindle is turned, the slider moves up and down inside the housing. The spindle, housing It is centered on the cover located on it, and between the shaft and the cover. Sealing is achieved using two alternative methods: 25 1. O-ring design; a nut is fitted onto the cover to support the shaft bearing. The nut The O-rings inserted inside provide a seal between the shaft and the nut. 2. Sealed design; a seal housing is used to support the shaft bearing. The shaft and... Packing material is placed between the housing and the packing pressure plate. The packing is compressed by tightening, thus creating a seal between the shaft and the cover. 30 It is provided. In some critical applications, being able to see the valve's open status is preferable. "Rising national" design is used in these types of applications. In this design, with a sliding mechanism... The shaft moves up and down as a whole, so when the slider comes up 35 The shaft rises above the cover fork. When the slide is lowered, the shaft also rises. 2 It descends along with it. Thus, the shaft on the lid fork lengthens. The valve opening can be determined by examining it. In a "non-rising stem" design, the stem is mounted on a slide. It is connected to the bolt via a nut, and when the shaft is rotated, the bolt moves along the shaft. It moves up and down. Thus, the axial movement of the shaft remains constant, and Position indication is not possible. 5 Rising shaft design; the shaft moves together with the slide, thus the cover fork. By raising it, the amount of the sliding door opening can be read. Non-rising shaft design; the slide moves on the shaft, thus the cover 10 Using a fork is not necessary. In different applications, the gate valve shaft can be driven in various ways: 1. Manual; manual opening and closing is achieved by connecting a handwheel (flywheel) to the shaft. 2. Motor (actuator); opening and closing with a motor by connecting an electric actuator. 15 This is ensured. In this application, the valve is manufactured with a ball flange cover, and thus The motor can be attached to the housing via a flange. As described above, gate valves come in two units each in four different categories. There are configuration alternatives. To meet these needs, valve 20 The covers need to be redesigned, resulting in a total of eight different covers. This results in increased inventory costs for manufacturers and improved part tracking. this creates a challenge and requires a complete cover replacement for configuration changes in the field. It makes going there mandatory. In conclusion, the existence of the above problems and the inadequacy of the current solutions, This has made it necessary to make improvements in the technical field.
