Description

Technical Field

[0001] The utility model belongs to the technical field of valve manufacturing, and in particular relates to an assembly device for a two-half type butterfly valve. Background Art

[0002] At present, the two-half butterfly valve consists of a lower valve body, an upper valve body, a butterfly plate and a valve stem (integrated), a valve seat, and screws at the joint. The assembly method is: 1. First install the integrated butterfly plate valve stem into the valve seat. 2. Place the lower valve body with the top flange facing down on an assembly platform with a round hole (the hole diameter is longer than the valve stem diameter). 3. Install the components assembled in step 1 into the upper valve body with the upper valve stem facing down, and the upper valve stem will be inserted into the hole on the assembly table. 4. Use tools to embed the valve seat into the valve body. Both the front and back sides need to be embedded, so the valve body needs to be turned by hand. 5. Align the lower valve body hole with the lower valve stem, and use tools to embed the valve body into the valve seat. Both the front and back sides need to be embedded, so the valve body needs to be turned by hand. 6. Hold the valve body steady with your hand or clamp it with a vise, and use tools to tighten the screws at the joint of the upper and lower valve bodies. As can be seen from the above, 1. The valve body needs to be rotated back and forth when it is embedded in the valve seat. 2. When tightening the joint screws, the valve body needs to be fixed by hand or with a vise. The production efficiency is low and there are certain safety risks. Therefore, it is necessary to carry out transformation. Utility Model Content
