The structure of the globe valve:
The structural forms of the globe valve body are straight-through, straight-through and right-angle. The straight-through type is the most common structure, but its fluid resistance is the largest. The direct-flow fluid resistance is small, and it is mostly used for Special design good price brass stop valve fluids containing solid particles or high viscosity. The right-angle valve body is mostly forged, which is suitable for the globe valve with smaller passage and higher pressure.
The installation and maintenance of the globe valve should pay attention to the following matters:
1. The globe valve operated by handwheel and handle can be installed in any position of the pipeline. 2. The handwheel, handle and Weidong mechanism are not allowed to be used for lifting. 3. The flow direction of the medium should be consistent with the direction of the arrow shown on the valve body.
The globe valve has the advantages of simple structure, convenient manufacture and maintenance, small working stroke, short opening and closing time, good sealing performance, small friction between sealing surfaces, and long service life.
