Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pipeline valve body maintenance, specifically relates to a movable support of auxiliary valve body dismounting. BACKGROUND

[0002] Various pipelines commonly used in the tobacco industry need to be connected by valve bodies, and the valve bodies are connected and sealed with the pipelines through flange bolts. In order to facilitate the timely maintenance of the problems such as leakage, damage and impurities that are prone to occur in the valve body, and prevent process quality problems and personnel injuries, such valve bodies need to be frequently dismounted or replaced.

[0003] After the valve body is dismounted, displacement of the two end pipelines and the flange plate is prone to occur due to force change, which makes it difficult to reinstall the valve body. Therefore, a tool is used to assist in dismounting the valve body during the present dismounting.

[0004] For example, CN202223473914.9 provides a horizontal pipeline valve body installation auxiliary tool, which adjusts the height of the support platform during the installation process, thereby lifting and supporting the valve body or the horizontal pipeline to maintain the position and facilitate the installation of the valve body or the horizontal pipeline, and facilitates the alignment of the valve body and the pipeline flange hole. The valve and the flange can be relatively fixedly supported, but the flange cannot be kept in the original position after the valve is dismounted.

[0005] Therefore, how to maintain the installation position before and after the valve body is dismounted is a technical problem to be solved in the field. UTILITY MODEL CONTENTS

[0006] In view of the existing phenomenon, the utility model provides a movable support for assisting in dismounting a valve body, which at least solves one of the above technical problems.

[0007] The technical scheme provided by the present application is a movable support for assisting in dismounting a valve body, which comprises: two fixing members for being inserted between the end of the valve body and the pipeline flange, and a connecting member for allowing the two fixing members to approach or move away from each other.

[0008] Further, an elastic member for pressing the pipeline flange towards the fixing member is further included, one end of the elastic member is fixedly connected with the fixing member, and the other end is detachably connected with the fixing member.

[0009] Further, the fixing member comprises an external thread, and the two ends of the connecting member comprise an internal thread section matched with the external thread.

[0010] Further, the fixing member comprises an internal thread, and the connecting member comprises an external thread section matched with the internal thread.

[0011] Further, the fixing member comprises a rotating connection part for connecting with the connecting member and rotating relative to other structures of the fixing member.

[0012] Further, the fixing member comprises a limiting part for limiting the side surface of the pipeline flange.

[0013] Further, the limiting part comprises a limiting bend perpendicular to the joint between the valve body end and the pipeline flange.

[0014] Further, the connecting member comprises a holding part for facilitating holding.

[0015] Further, the fixing member comprises an L-shaped supporting leg for being inserted at different positions between the valve body end and the pipeline flange.

[0016] Further, the L-shaped supporting leg forms an included angle of 60-90 degrees.

[0017] The application has at least the beneficial effect of providing an active support for assisting in dismounting a valve body. When the active support for assisting in dismounting a valve body is used, the distance between the two fixing members is first adjusted by the connecting member to match the size of the valve body, and the fixing members are inserted into the gap between the valve body end and the pipeline flange. Then the distance between the two fixing members is increased by the connecting member to tension the pipeline flange in the direction away from the valve body, so that the valve body can be easily separated from the pipeline while the position of the pipeline flange and the pipeline after the pipeline flange remains unchanged. After the valve body is separated from the pipeline flange, the active support of the application can keep the pipeline flange in a tensioned state, which is convenient for keeping the original installation position of the valve body and avoiding the re-alignment of the pipeline flange when the valve body is installed again. Therefore, the active support is beneficial to improve the dismounting efficiency of the valve body. BRIEF DESCRIPTION OF DRAWINGS

[0028] Embodiment 1 provides an auxiliary valve body dismounting movable support, comprising: two fixed parts 1 for being inserted between the end of the valve body and the flange of the pipeline, and a connecting part 2 capable of moving the two fixed parts 1 closer to or farther away from each other.

[0029] When the movable support of the auxiliary valve body dismounting device is used, the distance between the two fixing members 1 is adjusted by the connecting member 2 to match the size of the valve body, and the fixing members are inserted into the gap between the valve body end and the pipeline flange, then the distance between the two fixing members 1 is increased by the connecting member 2 to tension the pipeline flange in the direction away from the valve body, so that the valve body can be easily separated from the pipeline without changing the position of the pipeline flange and the pipeline behind it. After the valve body is separated from the pipeline flange, the movable support of the present application can keep the pipeline flange in a tensioned state, which is convenient for keeping the original installation position of the valve body and avoiding the re-alignment of the pipeline flange when the valve body is re-installed. Therefore, the movable support is beneficial to improve the dismounting efficiency of the valve body.

[0030] In the present embodiment, the two fixing members 1 include two external threads 1a with opposite rotation directions, and the connecting member 2 includes internal thread segments 2a at both ends which are matched with the external threads. Rotating the connecting member 2 can make the two fixing members 1 approach or move away from each other. The outer side of the connecting member 2 is easy to hold, and the two fixing members 1 can have a larger distance, which is suitable for dismounting longer valve bodies.

[0031] In the present embodiment, the fixing member 1 includes a limiting portion for limiting the side surface of the pipeline flange. Wrapping the side surface of the pipeline flange with the limiting portion can make the movable support more stable and fixed with the pipeline flange, and reduce the accidental sliding out of the movable support from the gap between the valve body end and the pipeline flange.

[0032] In the present embodiment, the limiting portion includes a limiting bend 12 which is perpendicular to the joint between the valve body end and the pipeline flange. The limiting bend 12 is easy to implement and can function as a limiting portion. In other embodiments, the limiting portion can also be shaped to match the shape of the pipeline flange.

[0033] Considering that more contact between the fixing member 1 and the pipeline flange can make the support effect of the movable support more stable, but enough circumferential space needs to be reserved for the valve body to move in and out during dismounting, in the present embodiment, each fixing member 1 includes two L-shaped legs 11 for insertion at different positions between the valve body end and the pipeline flange, and the L shape can ensure the contact degree and have enough space for the valve body to move in and out. The L-shaped fixing member is easy to process and convenient to implement. In the present embodiment, the included angle formed by the two legs 11 is 90 degrees. The smaller the included angle, the less likely the movable support will accidentally slide out, but the dismounting operation space will also be smaller. When the included angle formed by the two legs 11 is 60-90 degrees, both can be better considered.

[0034] Embodiment 2 provides another movable support for assisting in dismounting a valve body, which includes two fixing members 1 for insertion between the valve body end and the pipeline flange, and a connecting member 2 which can make the two fixing members 1 approach or move away from each other.

[0035] The embodiment 2 further comprises an elastic member 3 for pressing the pipe flange against the fixing member 1, one end of the elastic member 3 is fixedly connected with the fixing member 1, and the other end is detachably connected with the fixing member 1. The elastic member 3 in the embodiment is an elastic rope, one end of the elastic rope is fixedly connected with the fixing member 1 through a nut, and the other end is detachably connected with the fixing member 1 through a hook. When installing the movable support, the detachable end of the elastic rope is first detached, the fixing member is inserted between the valve body end and the pipe flange, and then the elastic rope is wound outside the pipe flange, so that the pipe flange is pressed against the fixing member 1, and the movable support is more stably connected with the pipe flange.

[0036] In the embodiment, the two fixing members 1 comprise inner threads in opposite directions, and the connecting member 2 comprises an outer thread section 2b matched with the inner threads. In the embodiment 1, the two fixing members 1 comprise outer threads 1a, and the connecting member 2 comprises an inner thread section 2a. The limit position of the two fixing members 1 approaching each other is limited by the length of the inner thread section 2a of the connecting member 2, and the deeper inner thread section 2a is not easy to process in the connecting member 2. In the embodiment 2, the connecting member 2 has the outer thread section 2b, which is easy to implement as a longer length, and is convenient for the two fixing members 1 to approach each other.

[0037] Considering that the threaded connection can make the two fixing members 1 approach or move away from each other, the two fixing members 1 will also rotate relative to the connecting member 2 at the same time, which is not convenient for the fixing member 1 to fully contact the pipe flange. In the embodiment, the fixing member 1 comprises a rotating connection part for connecting with the connecting member 2, which can rotate relative to other structures of the fixing member 1. As an implementation manner of the rotating connection part, the inner thread of the fixing member 1 is rotatably connected with other structures of the fixing member 1 through a bearing 4, so as to keep the posture of the fixing member 1 when adjusting the distance between the two fixing members 1.

[0038] Considering that the connecting member 2 provided with the outer thread section is easy to hurt the hand when directly holding the thread, in the embodiment, the connecting member 2 comprises a holding part 21 for convenient holding.

[0039] The above description can be implemented alone or in various combinations, and these variants are within the protection scope of the utility model.

[0040] It is to be noted that the relational terms herein, such as first and second, and the like, are used solely to distinguish one from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
