Stone renovation work procedures and construction methods: 1 In the work site to set up signs, in order to prevent mud dirt splashed on the walls, with plastic transparent film to paste the bottom of the wall surrounding the floor. Add clean water to the stone refurbished water tank, connect the power supply, and prepare various types of Hong Kong brand metal grinding plates, renewal pieces, water mills, etc., and adjust the level of equipment and the ground to prepare for work. If there is old wax on the ground, wax first. 2 Use 50 # metal grinding pieces 6 pieces, respectively screwed on two grinding head plate, add two pieces of a total weight of 50 kg of iron, stone refurbishment speed is adjusted to 500 rev / min or so, water and start Motor grinding. Each time about 1 square meter of grinding area, repeatedly push and pull 3 to 5 times, the stone cut part of the grinding to smooth, moderate water when grinding, dry grinding is prohibited, with a suction machine to dry, suction net. 3 Replace the 150# metal grinding pad and the 300# metal grinding pad, grinding according to the order, leveling and cutting to eliminate rough wear marks. Repeatedly grinding, scraping and drying the floor. 4 Using 200 #, 500 #, 800 # grinding, the machine speed of 500 rev / min to continue grinding. 5 The 1500# and 3000# polishing pads are used to polish the surface. At this time, the two weighted irons on the machine are removed, the rotation speed is increased from 500 rpm to 650 rpm, and the stone surface is washed. , blow dry, showing brilliant colors. Some of the stone color change after the refurbishment, such as lighter, because the stone before the factory in order to reduce the color difference has been done a special coloring, and these special colorants in the refurbishment grinding process is ground away, restore the original appearance of the stone, so Dark stone fades, lightens, and color shifts occur. Yirui company according to the characteristics of each different dark stone, a little processing, you can reduce the color, basically restore the original color of the stone.

Regulating Valve
Regulating valve is a fluid control device, it can control fluid flow, pressure, temperature and other parameters, in order to achieve the purpose of regulating fluid flow characteristics. It is composed of a piston or ball spool, in which there is a manual or electric mechanism with adjustment function, it can control the position of the piston or ball spool, so as to change the pressure and flow rate in the valve, so as to adjust the flow characteristics of the fluid.
The main function of the regulating valve is to adjust the flow rate, pressure and temperature, so that the fluid flow characteristics are more stable, so as to improve the efficiency of the fluid. It can regulate the flow of fluid to keep it at a low level, thus saving energy; The pressure of the fluid can also be adjusted to keep it at a low level, thus reducing noise in the piping system; The temperature of the fluid can also be adjusted to keep it at a low level, thus preventing condensation in the piping system, etc.
