Description

Technical Field

[0001] The utility model relates to the technical field of assembly devices, in particular to a stop valve assembly device. Background Art

[0002] The globe valve is a widely used valve type, also known as a cut-off valve or cut-off valve. It is a forced sealing valve. When the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. The opening and closing part of the globe valve is a plug-shaped valve disc with a flat or conical sealing surface. The valve disc moves linearly along the center line of the fluid.

[0003] The assembly of a globe valve involves multiple steps and key points. Before installation, check whether the packing is intact, whether the gland bolts have sufficient adjustment margin, and whether the valve stem and valve disc are intact and whether there is any sticking or skew. The specific installation steps may vary depending on the valve type, specifications, application environment and production requirements.

[0004] The prior art patent document CN213003650U provides a labor-saving stop valve assembly machine. The valve body and valve core of the device only need to be initially matched, and then tightened by a tightening mechanism. After tightening, it falls from the discharge port into the receiving barrel, which has the characteristics of saving time and labor.

[0005] The above-mentioned prior art, although the device is tightened by a tightening mechanism and falls from the discharge port into the receiving barrel after tightening, which has the characteristics of saving time and labor, however, the assembly device in the patented technology directly falls through the discharge port into the receiving barrel for collection after assembly is completed, and the valve body is directly adjusted into the receiving barrel. The fall of the valve body has a certain impact force, and excessive impact force may cause damage to the valve body. There is no mechanism to protect the valve body, which reduces the production quality of the stop valve. Therefore, we need a stop valve assembly device. Utility Model Content
