Nowadays, in developed cities, subways or station-top buses have become very popular. I wonder if you have noticed that when you wait for the subway, there is a fully enclosed door that separates the track from the platform. This kind of door is the screen door. It is necessary to install the screen door and the matching waveguide outlet gold and observation window in the subway. Nowadays, in the developed cities, the subway or the station bus has become very popular. I wonder if you pay attention to it. When you wait for the subway, there is a fully enclosed door that separates the track from the platform. This kind of door is the screen door. It is necessary to install the screen door and the matching waveguide air inlet and observation window in the subway. Let's take a look at how to install them!
Screen door installation method:
1. When the screen door is moved and installed, the sealing knife and sealing spring of the door leaf and the door frame should be effectively protected to avoid deformation or damage caused by collision.
2. The shielding door frame should be vertically and horizontally corrected during installation, and the connection between the shielding door and the door opening should be firm, reliable and seamless.
3. When the door leaf is installed, the mounting hole of the door hinge should be positioned and corrected on the door frame, and then all the fasteners should be fixed.
4. After installing the opening and closing manual mechanism of the screen door, electric or pneumatic device, test the closing condition of the door. The test structure should be reliable and flexible to rotate, and the sealing knife is in good contact with the sealing reed.
5. After the installation is completed, various contact points should be tested. After the test is passed, spray anti-rust paint. When performing this procedure, the sealing knife and the sealing spring should be covered and not stained.
The waveguide tuyere and observation window should be treated as follows before installation:
1. The paint layer and the rust surface of the interface between the waveguide tuyere and the steel sheet wall are polished and uniformly tinned.
2. The bracket of the waveguide tuyere and the keel of the slab wall are welded or fixed by screws, and the wall surface must not be destroyed. All brackets should be straight and strong.
3. The lens on both sides of the observation window and the intermediate waveguide or metal mesh are inlaid firmly and tightly with the observation window frame. The contact between the window frame and the wall should be evenly tinned. The waveguide duct and the observation window should be installed on the wall assembly to be reliable and straight.
4. The inner and outer contact surfaces of the waveguide duct and the observation window must be tight and smooth.
5. The welding port should be coated with conductive paint and anti-rust paint according to the design requirements, and the brush should be evenly leaked.
6. After the waveguide air duct is installed, it is covered by the baffle and removed during acceptance.
The above is the installation method of the screen door for everyone. Many people often cannot understand the existence of the screen door. In fact, the screen door plays a very important role. The screen door not only helps the platform to save air conditioning energy, but most importantly, it protects the personal safety of passengers on the subway. Despite the protection of the screen door, everyone should pay attention to safety when taking the subway.
