1. Control valve should be installed before the pipeline dirt, rust grease and slag, etc. to be cleaned; after installation, the valve should be at the maximum opening of the pipeline, the valve to clean and test the sealing of the joints, so as to avoid Slipping phenomenon occurs during operation or damaged spool, seat.
2. Should be installed near the ground or floor to facilitate maintenance and repair; for semi-valve with a valve positioner or hand wheel mechanism, should ensure that the observation, adjustment and operation of the convenience.
3. During installation, the direction of the medium should be the same as the arrow on the valve body.
4 installation should avoid additional stress to the control valve, so as to avoid the temperature or weight of the valve flange deformation and damage, when the valve is installed in the pipe longer place, should be installed support frame, especially in the use of Vigorous occasions must be supported or take appropriate vibration isolation measures. Large-diameter control valve should be installed to avoid tilt, to prevent the valve trim mechanical wear and packing leakage, which should pay special attention.
5. For safety reasons, the pneumatic control valve should be added bypass pipeline (important occasions), in order to control valve failure or maintenance, will not stop production.
6. With handwheel mechanism, the valve can be manually operated, but also can be used to limit the valve opening. In the use of automatic control, the hand wheel mechanism must be placed in neutral position.
7. For high temperature valves, greasing should be applied to the packing section every three months.
The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
PVC furniture edge banding is relatively light, which is relative to metal and plexiglass. The reason for the lightness is not because it is a polymer compound, but because they are organic compounds, which are composed of carbon, hydrogen, oxygen, and chlorine. And other lighter elements.
The material of pvc furniture edge banding is plastic, which is easy to process. Plastic has plasticity, that is, it deforms after heating or pressurizing, and maintains its original shape after the temperature drops or the pressure disappears. It can be processed into edge bands of their respective shapes by extrusion and other methods, such as T-shaped edge bands, H-shaped edge bands, D-shaped edge bands, V-shaped edge bands, I-shapes, and so on.
pvc furniture edge banding is of high quality and low price, and the price of plastic is far less than that of metal.
