Abstract
The invention relates to a quick assembling tool and method for a V-shaped gate valve flashboard. The tool is of a pincer-shaped structure, and the pincer-shaped structure is formed by connecting two identical S-shaped arc structures. Assembling the flashboard, the valve rod and the valve cover assembly, hoisting the assembly to the upper part of the valve body, matching the flashboard with the guide groove of the valve body, and enabling the lower edge of the flashboard to fall into the valve seat; penetrating a V-shaped gate valve flashboard quick assembly tool into a valve cavity through a gap between a valve cover and a valve body, clamping a lower opening of the flashboard flat by using the V-shaped gate valve flashboard quick assembly tool, then dropping the valve cover assembly by 2cm integrally, and taking out the V-shaped gate valve flashboard quick assembly tool after the flashboard falls into a valve seat; and finishing the valve assembly. The gate valve gate plate with the spring double gate plate can be quickly assembled, the influence of insufficient maintenance space on maintenance activities is reduced, the injury risk of maintenance personnel is eliminated, the gate valve assembling time is shortened, and the gate valve assembling efficiency is improved.
Description
Technical Field
The invention relates to a quick assembling tool and a quick assembling method for a gate plate of a V-shaped gate valve (a parallel double-gate-plate gate valve with a spring), which can improve the assembling efficiency of the gate valve and reduce the risk of personal injury.
Background
A process system of a nuclear power station is provided with a large number of parallel double-flashboard gate valves with springs in the middle, and the springs are used for forcing a flashboard sealing surface to be in contact with a valve seat to provide pre-tightening sealing force. The assembled shutter is constrained by the valve seat, with the spring in a compressed state. In order to avoid the situation that a spring between the flashboards suddenly releases the spring force to hurt people in the disassembly and maintenance process of the valve, a limiting frame is arranged at the joint of the flashboards and the valve rod. Because the spring is located flashboard central point and puts, spacing is located flashboard border position, and the flashboard loses the restraint of disk seat when disassembling, and spring force and spacing combined action make the flashboard appear "opening under one's mouth". Taking DN150 gate valve as an example, the opening size of the gate plate is about 1cm wider than the distance between the sealing surfaces of the valve seats. The valve gap subassembly hoist and mount to the valve body top, and when the flashboard was about to fall into the disk seat, the clearance between valve gap and the valve body was no longer than 10 cm. When the valve is assembled, the 'opening' exists, and an external force is needed to assist the flashboard to enter the valve seat. The auxiliary shutter is pressed by hands of a maintainer or pressed by a tool to press the lower edge of the shutter assembly to fall into the valve seat.
This assembly process has the following problems: in the assembling process, before the flashboard falls into the disk seat, the space between the valve cover and the valve body is smaller, so that the operation of maintenance personnel is inconvenient. The operation that the supplementary gate valve of maintainer fell into the disk seat needs with valve gap subassembly hoist and mount synchronous operation, if two work cooperations are not good, have the injured risk of maintainer. The method has long time consumption and low efficiency.
Disclosure of Invention
The invention aims to provide a simple and reliable quick assembling tool and method for a V-shaped gate valve gate plate, which are used for assembling the gate plate of a V-shaped gate valve (a double-gate-plate parallel gate valve with a spring).
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the utility model provides a V type gate valve flashboard fast assembly instrument, this instrument is the pincerlike structure, and this pincerlike structure is formed by two the same S-shaped arc structures connection.
A quick assembling method for a V-shaped gate valve gate plate comprises the steps that a gate plate, a valve rod and a valve cover assembly are assembled and hoisted to the position above a valve body, the gate plate is matched with a guide groove of the valve body, and the lower edge of the gate plate is about to fall into a valve seat; penetrating a V-shaped gate valve flashboard quick assembly tool into a valve cavity through a gap between a valve cover and a valve body, clamping a lower opening of the flashboard flat by using the V-shaped gate valve flashboard quick assembly tool, then dropping the valve cover assembly by 2cm integrally, and taking out the V-shaped gate valve flashboard quick assembly tool after the flashboard falls into a valve seat; and finishing the valve assembly.
The beneficial effects obtained by the invention are as follows:
use V type gate valve flashboard fast assembly instrument, can realize taking the fast assembly of spring double-disc gate valve flashboard, reduce the influence of examining and repairing the activity that the space is not enough, eliminate the injured risk of maintainer, shorten the gate valve assemble duration, promote the gate valve packaging efficiency. The tool can effectively clamp the flashboard in a small space to eliminate a downward opening, and smoothly realize the operation of installing the flashboard into the valve body.
Drawings
FIG. 1 is a schematic view of a V-shaped gate valve plate quick assembly tool I;
fig. 2 is a schematic view II of a V-shaped gate valve plate quick assembly tool.
Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments.
The invention designs a set of quick assembling tool for the gate plate of the V-shaped gate valve, and the assembling can be smoothly realized after the 'downward opening' of the gate plate is eliminated. Because the lower edge of the flashboard is not in the same plane with the gap and the edge of the valve cover, a long and straight tool cannot be used for clamping, so that the tool is designed into an arc-shaped structure, the valve cover and the valve body can be smoothly assisted by the gap between the valve cover and the valve body to fall into the valve body, and the clamping tool can be smoothly taken out after the valve falls into the valve body.
As shown in fig. 1 and 2, the quick assembling tool for a V-shaped gate valve and a gate plate of the present invention is a pincer-shaped structure, and the pincer-shaped structure is formed by connecting two identical S-shaped arc structures.
The quick assembling method of the V-shaped gate valve flashboard using the tool comprises the following steps:
the gate plate, the valve rod and the valve cover assembly are assembled and hoisted to the upper portion of the valve body, the gate plate is matched with the guide groove of the valve body, and the lower edge of the gate plate is about to fall into the valve seat. In wearing the valve pocket with V type gate valve flashboard fast assembly instrument through the clearance between valve gap and the valve body, use V type gate valve flashboard fast assembly instrument with the flashboard under the mouth clamp tie, then fall down the whole 2cm of valve gap subassembly about, treat that the flashboard falls into the disk seat after, take out V type gate valve flashboard fast assembly instrument. And the rest are assembled according to a normal assembly procedure.
