Problems solved by technology

At the same time, the order of installing the sliding bearings of the existing assembly tool must be to install the valve stem first, use the valve stem as a positioning mandrel and then install the sliding bearings
If the assembly sequence is changed, the sliding bearing will be easily pushed out when the valve stem passes through the sliding bearing because the gap between the two is too small, resulting in assembly rework; at the same time, it is easy to damage the surface of the valve stem, valve cover, and sliding bearing, causing unnecessary damage. Rework reduces production efficiency and increases manufacturing costs

Abstract

The invention relates to the technical field of valves, and discloses a sliding bearing assembly tool and an assembly method thereof, including a compression nut, a friction gasket, a shaft sleeve and a compression ring, the shaft sleeve is fixed in a stuffing box of a valve cover, the compression ring, The friction pad is coaxial with the shaft sleeve and arranged in the shaft sleeve. The friction pad abuts against the top of the pressure ring, and the top of the friction pad abuts against a compression nut, and the compression nut is threadedly connected with the valve stem. In the sliding bearing assembly tooling of the present invention, the overall tooling adopts a split assembly structure, and the accurate assembly of the parts can be quickly realized by rotating the compression nut, and the disassembly is convenient, which improves the assembly efficiency of the valve; during the assembly process of the parts, the sliding bearing can be prevented. , The damage of the contact parts of the valve stem and the valve cover ensures the overall quality of the product.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a sliding bearing assembly tool and an assembly method thereof. Background technique [0002] The sliding bearing is an important supporting part in the valve body cavity. It provides effective support for the valve stem to ensure its rotation accuracy, and can also reduce friction, reduce the opening and closing torque of the valve, and protect the surface of the valve stem. [0003] For valves with elastic sliding bearings installed at the bottom of the stuffing box at the upper end of the bonnet, the sliding bearing material is metal surface sprayed with lubricating materials, mostly thin-walled cylindrical, split-slotted, self-lubricating structures; when in use, the outer circle of the sliding bearing and the valve cover Cooperate, its inner circle cooperates with valve stem. The installation position of the sliding bearing is generally the bottom of the small-diameter deep ...
