　　(1) Types of valves


　　1. Classified by role and use


　　(1) cut-off valve: cut-off valve is also known as closed circuit valve, shut-off valve, its role is to connect or cut off the medium in the pipeline. Cut-off valve types include gate valves, globe valves, plug valves, ball valves, butterfly valves and diaphragm valves, etc.


　　(2) Check valve: check valve is also known as one-way valve or check valve, its role is to prevent the backflow of media in the pipeline. Its main role is to prevent the backflow of the medium, to prevent the pump and drive motor reversal, as well as the release of the container medium. Water pump suction off the bottom valve also belongs to the check valve category.


　　(3) Safety valves: the role of safety valves is to prevent the pipeline or device in the medium pressure exceeds the specified value, so as to achieve the purpose of safety protection.


　　(4) Regulating valves: regulating valves include regulating valves, throttling valves and pressure reducing valves, whose role is to regulate the pressure of the medium, flow and other parameters.


　　(5) Diverter valves: Diverter valves include a variety of distribution valves and traps, etc., whose role is to distribute, separate or mix the media in the pipeline.


　　(6) Exhaust valves: Exhaust valves are essential auxiliary components in piping systems and are widely used in boilers, air conditioning, oil and gas, and water supply and drainage pipelines. They are often installed at high points or elbows to remove excess gas from the pipeline, improve the efficiency of the pipeline and reduce energy consumption.


　　2. Classified by nominal pressure


　　(1) Vacuum valve: refers to the valve whose working pressure is lower than the standard atmospheric pressure.


　　(2) Low pressure valve: refers to the nominal pressure PN ≤ 1.6Mpa valve.


　　(3) Medium pressure valve: refers to the nominal pressure PN 2.5, 4.0, 6.4Mpa valve.


　　(4) High pressure valve: refers to the valve with a nominal pressure PN of 10~80Mpa.


　　(5) ultra-high pressure valve: refers to the nominal pressure PN ≥ 100Mpa valve.


　　3. classified by working temperature


　　(1) ultra-low temperature valve: for the medium working temperature t<-100 ℃ valve.


　　(2) low-temperature valve: for the medium working temperature -100 ℃ ≤ t ≤ -29 ℃ valve.


　　(3) room temperature valve: for medium working temperature -29℃


　　(4) medium temperature valve: for the medium working temperature 120 ℃ ≤ t ≤ 425 ℃ valve.


　　(5) high temperature valve: for the medium working temperature t>450℃ valve.

Carbon steel pipe fittings groove fittings surface should be flat, clean, there should not affect the performance of porosity, sand eyes, slag, cold compartment, shrinkage, cracks and depressions and other defects. Cast groove parts should be free from defects such as bulges and depressions. Grooved fittings should be free from processing defects and knock-on damage. Markings should be clear and rowable.

Carbon steel pipe fittings can be coated with electrophoretic paint, plastic or hot dip galvanising for surface and corrosion treatment, where the electrophoretic paint coating method of trench fittings should not be used for domestic drinking water supply. The dimensions of the trench interface after surface treatment shall conform to the provisions of Appendix C of GB/T36019-2018, and the corrosion protection layer shall conform to the following provisions respectively:

 ) paint layer: uniform, smooth, firm, no paint tumor, accumulation of paint, leakage of paint, paint layer thickness of not less than 25.4 &undefined;, paint layer containing less than 0.009% of lead.

b) The plastic layer is uniform, continuous, smooth and firm. Epoxy coating thickness of plastic coated trench fittings should be not less than 130, by mutual agreement between supply and demand, can be specified epoxy coating thickness greater than 130 other thickness of polyethylene coating thickness should be in line with the same nominal size steel-plastic pipe plastic layer thickness requirements in Table 2. The plastic layer should be covered intact at the installation with parts such as the groove of the pipe fittings, and the thickness should be not less than 40 and not affect the installation.

c) hot dip galvanized layer: zinc layer uniform, continuous, smooth, no leakage, zinc layer off, black spots and other defects and rubber ring / pad contact surface should not be zinc tumor, zinc slag, pile of zinc and other appendages zinc layer of lead content of not more than 0.1% zinc layer thickness of not less than 65 .

Carbon steel pipe fittings bolts, nuts should be hot-dip galvanized surface corrosion treatment, and comply with the provisions of GB/T5267.3. Galvanized layer thickness should be not less than 40 galvanized layer surface should be smooth, no leakage, zinc tumor, black spots, no residual solvent slag, oxide inclusions and other defects that damage the intended use of parts performance. Preference shall be given to hot-dipped galvanized bolts and nuts. By mutual agreement between supply and demand, other materials and coated bolts and nuts can be supplied.

On September 3, the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War, our company organized all employees to watch the grand military parade. The impeccably aligned formations, powerful and rhythmic strides, dignified and heroic troops, and advanced sophisticated equipment filled every employee with immense pride and excitement.


This magnificent parade not only demonstrated the nation’s strong defense capabilities but also highlighted the unity, determination, and uplifting spirit of the Chinese people.
