It uses platform with V-shape frame, uses link rod mechanism to elevate platform, and makes static weighing by making disk away from C-shape hook or steel roll away from bracket.
It can be widely used for online weighing of steel disk or steel roll in steel rolling plant.
It has V-shape platform, and realizes stable and reliable placement of disk;
Removal elevation mechanism design is convenient for maintenance and repair;
It is driven by hydraulic cylinder, and has stable elevation speed;
Scale frame has excellent structure, rational limit, quick and reliable weighing.

Safety valve installation and maintenance and precautions
Safety valve flap opening height can be divided into micro-type safety valve and all-relief valve, micro-open safety valve opening stroke height: ≤ 0.05D0 (minimum discharge throat caliber); Full-opening safety valve opening height ≤ 0.25D0 (minimum discharge throat caliber). Safety valve is a kind of safety protection valve, its opening and closing parts are normally closed under the external force. When the medium pressure in the equipment or pipeline rises and exceeds the specified value, it will be automatically turned on. The medium is discharged to the outside of the system Medium pressure in pipe or equipment exceeds specified value. Safety valves are automatic valves, safety valves are mainly used in boilers, pressure vessels and pipes, the control pressure does not exceed the specified value, the personal safety and equipment plays an important protective role. Safety valve according to the structure of the points, should be divided into vertical hammer, lever type, spring type and pilot type (pulse type); According to the valve body structure can be divided into closed and not closed two. Closed safety valve that is not excluded from the media, all along the exit to the designated location, generally used in toxic and corrosive media. For air and steam safety valve, multi-use non-enclosed safety valve. For the selection of safety valve products, the actual sealing pressure should be determined. For spring-loaded safety valves, springs with several working pressure ratings within a nominal pressure (PN) range should be specified when ordering, in addition to indicating the safety valve model, name, medium, and temperature , Otherwise according to the maximum sealing pressure supply. Safety valve installation and maintenance should note the following: All kinds of safety valves should be mounted vertically. Safety valve outlet should be no resistance, to avoid compression phenomenon. Safety valve should be specially tested before installation, and check its official seal. The use of safety valves should be regularly checked.
