Information
The general valve of Liaoyang valve has a direction mark on the valve body; if not, it should be correctly identified according to the working principle of the valve.
The valve cavity of the shut-off valve is asymmetrical left and right. The fluid must pass through the valve port from bottom to top, so that the fluid resistance is small (determined by the shape), and the opening is labor-saving (because the medium pressure is upward), and the medium does not press the packing after closing, which is convenient for maintenance . This is the reason why the globe valve cannot be reversed. Other valves also have their own characteristics.
The location of the valve installation must be convenient for operation; even if the installation is temporarily difficult, it is necessary to consider the long-term work of the operator.
It is best to keep the valve handwheel flush with the chest (usually 1.2 meters away from the operating floor), so that it is easier to open and close the valve. The hand wheel of the floor valve should be upwards, do not tilt, to avoid awkward operation. The valve of the wall machine and the equipment should also leave room for the operator to stand. It is necessary to avoid operating from the sky, especially acid and alkali, toxic media, etc., otherwise it is very unsafe.
The cleaned parts must be sealed and stored for installation. The requirements for the installation process are as follows:
1. The installation workshop must be clean, or set up a temporary clean area, such as newly purchased color striped cloth or plastic film, to prevent dust from entering during the installation process.
2. Assemblers must wear clean cotton overalls, cotton caps, no leakage of hair, clean shoes on feet, plastic gloves on hands, and degreasing.
3. The assembly tools must be degreased and cleaned before assembly to ensure cleanliness.
The control components in the fluid conveying system have the functions of cut-off, regulation, diversion, prevention of reverse flow, stabilization, diversion or overflow and pressure relief.
Valves used in fluid control systems, ranging from the simplest shut-off valves to the various valves used in extremely complex automatic control systems, have a wide range of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.) according to materials, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard customized valves and other valve materials .
