Executive mode converting support applied to valve, and executor mounting mechanism

Abstract

The invention relates to an executive mode converting support applied to a valve, and an executor mounting mechanism. The executive mode converting support comprises a disc-shaped main body placed ona hand wheel gland, and the disc-shaped main body is provided with a sleeve hole, wherein the sleeve hole is coaxial with a hand wheel valve rod hole, and a protruding part is sleeved with the sleevehole. The upper end face of the disc-shaped main body is used for storing an executor, and the outer diameter of the disc-shaped main body is larger than that of the hand wheel gland. The disc-shapedmain body corresponds to all threaded mounting holes of the hand wheel gland and provided with a counterbore hole in the vertical direction, the outer diameter of the disc-shaped main body is larger than that of the hand wheel gland, and the portion, on the periphery of the hand wheel gland, of the disc-shaped main body is provided with circumferentially-distributed external mounting holes in thevertical direction. By adopting the technical scheme, according to the executive mode converting support applied to the valve, on the basis that the gland is not dismantled, the gland structure is changed so as to adapt to a hand wheel or the executor, and the executive mode converting support has the advantages that labor and materials are saved, the mechanical property is better, the valve height is decreased, the occupied area is reduced, and the service life of a sealing assembly is prolonged.

Description

technical field [0001] The invention relates to the field of valves, in particular to an execution mode conversion bracket applied to valves, and also to an actuator installation mechanism with the above-mentioned execution mode conversion bracket. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications....

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned glands all have certain disadvantages. In order to provide the upper mounting flange with upside-down bolts and the lower mounting flange, the actuator gland is equipped with a connecting column to increase the distance between the upper mounting flange and the lower mounting flange. Reserve space for the head of the bolt, but the setting of the connecting column makes the section of the middle part of the actuator gland smaller, resulting in a decrease in the strength of the middle part of the actuator gland. In addition, it not only increases the material used for the gland, but also At the same time, the material used for the valve stem passing through the gland is increased, resulting in a waste of materials; secondly, when the same valve body switches the execution mode online, it is necessary to remove the original corresponding gland and reinstall the corresponding gland. The disassembly method is not only inconvenient to disassemble, but also the sealing assembly between the valve stem hole and the valve stem will be consumed when the gland is removed, resulting in a decrease in the sealing performance after the second installation, or an increase in the use cost caused by the placement of a new sealing assembly
