The escalator is the passenger carrying equipment with the highest continuous transportation efficiency between floors of buildings. In the commercial complex with huge pedestrian flow, the escalator has become one of the important carriers to carry and guide the flow of people and maximize the commercial value. In the design of shopping center, escalator design is an important part of moving line design. The ingenious escalator design can enhance the customer experience and effectively attract the passenger flow to the high-rise building.

How to properly use and maintain the stopcock
How to properly store, install, use and maintain the stopcock: 1. The stopcock should be stored in a cool and dry place. Do not expose it to ozone and sunlight. When it is stored, the cock should be in the fully open position, and both ends of the channel need to be sealed. If the cock is not used for a long time, check and replace the anti-rust oil on time every six months. 2, Before installation, the sealing surface and body cavity oil should be wiped so that the valve can maintain good sealing performance. 3, Stopcock valve should be carefully checked before installation whether the working conditions with the valve performance. 4, eccentric plug valves for solids without suspended solids can be installed in any orientation. Line pressure should be applied from the opposite side of the valve seat to the tap. 5. Eccentric plug valves for solids containing suspended solids, when mounted on a horizontal line, have the same shaft orientation as the media entering the valve body from the seat end. Rotate the cock counterclockwise to open the valve and the cock remains in the upper half of the valve body. When installing the valve on a vertical line, the direction of the seat end should be as shown in Figure 2. 6, the installation can not use the lever or long hand too much force to operate too much. 7, the installation is completed, the intensity of pressure test should open the valve. 8, should regularly check the wear and tear of the sealing position of the plug valve to ensure its normal use.
