Description

Technical Field

[0001] The utility model relates to the technical field of valve equipment, in particular to a gate valve handwheel rotation assembly. Background Technique

[0002] At present, the problem of valve packing leakage is extremely common. The main reasons are as follows: First, the opening, closing or adjustment of the valve is completed by rotating the valve stem. The gap between the rotating valve stem and the stationary valve body needs to be sealed with packing to prevent the leakage of the medium. Second, jamming often occurs among the valve stem, the packing and the valve body, making it difficult for the valve stem to operate. Due to the defects in the structure of the transmission valve itself, it is easy to cause the leakage of the packing seal of the valve. The gate valve handwheel is an essential accessory in the valve.

[0003] However, after long-term use of the current gate valve, liquid is likely to leak at the valve stem, thus greatly reducing the practicability of the equipment. Therefore, we propose a gate valve handwheel rotation assembly to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a gate valve handwheel rotation assembly to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A gate valve handwheel rotation assembly includes a gate valve mounting plate. A valve stem is sleeved on the outer surface of the gate valve mounting plate. A connecting column is clamped on the upper surface of the valve stem. Annularly arranged support rods are fixedly connected to the outer surface of the connecting column. Annularly arranged balls are fixedly embedded in the inner wall of the gate valve mounting plate. A first gasket and a second gasket are respectively fixedly connected to the inner wall of the gate valve mounting plate. A card slot is opened at the bottom surface of the gate valve mounting plate. A sealing ring is clamped at the bottom surface of the gate valve mounting plate. A connecting rod is fixedly connected to the bottom end of the valve stem.

[0007] In a further embodiment, annularly arranged mounting holes are opened on the upper surface of the gate valve mounting plate. A mounting screw is threadedly connected to the inner wall of each mounting hole.

[0008] In a further embodiment, a sealing ring is sleeved on the outside of each mounting screw. The outer surface of each ball is in contact with the outer surface of the valve stem.

[0009] In a further embodiment, a clamping block is fixedly connected to the bottom surface of the connecting column. A groove is opened on the upper surface of the valve stem.

[0010] In a further embodiment, limiting holes are formed in both the outer surface of the valve stem and the front surface of the clamping block, and a limiting screw is commonly connected to the inner walls of the two limiting holes by threads.

[0011] In a further embodiment, annular handles are commonly fixedly connected to the ends of the six support rods far away from the connecting column, and an anti-slip layer is fixedly connected to the outer surface of the annular handles.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the cooperation of the first sealing gasket, the second sealing gasket, the clamping groove, the sealing ring and the sealing washer, the device can not only make the sealing effect of the equipment better, but also facilitate the staff to replace the sealing ring, thereby greatly increasing the practicability of the equipment. The cooperation of the clamping block, the clamping groove, the limiting hole, the limiting screw and the anti-slip layer can not only facilitate the staff to disassemble and assemble the annular handle, but also facilitate the staff to use the equipment.
