Q:The general signal valve installation, or other valve installation is not installed with the groove flange clamp hoop Yucca or direct way? What's the convenient way to install the following diagram? I don't understand. Neither groove, flange nor hoop. Thank you, sir!: The blue one is the separate body, and the red one is the welded flange on the pipe. There is rubber on the valve body, and it can be sealed with flange. This is determined by the structure of the butterfly valve, usually DN150 of the small diameter butterfly valve are installed this way. It comes with flanges, but the prices are much higher. Small caliber general butterfly valve is generally used for low pressure, leakage requirements are not high, so rarely use its own flange. With flanges, it is generally used in petrochemical systems and has a much higher pressure level.

Q:Valve pressure grade division: Nominal pressure PN is less than 1.6Mpa valve is low pressure valve, nominal pressure PN2.5 - 6.4MPa valve is the pressure valve, nominal pressure PN10.0 - 80.0MPa valve high pressure valve.

Q:The valve has a clear opening and closing sign. What does this sentence mean?: Simply speaking, a gate valve, hand wheel will be above the arrow and open and close the text, indicating that you are clockwise valve open or counterclockwise valve open, so as not to make mistakes, accidents. Other valves are similar in sense and sign.

Q:the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?: Pro, strong counterpart refers to the valve in the pipeline connection, generally refers to the thread connection or welding to connect the valve, the valve and pipeline connection imposed by the larger external force, it will cause great stress and plastic deformation, easy to cause the valve to open or close the lax.

Q:Symbols for all types of valves: Look at the attachment I gave you. The legend of the valves is complete!

Q:What is the use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism: Tyco doesn't know much about it. It's often written in the bidding documents, but there are very few actual purchases, so I don't evaluate it any more. The strongest of the balance valves is the TA (Swedish). He was the originator of the balancing valve. Super high-rise complex, the hotel part, you mention these kinds of valves are applied a lot.

Q:What does the valve stroke mean?: The distance from one position to another. Usually in the first position of the cut position, the second position is put through the position. Unless the valve has 3 positions.

Q:How to carry out the valve strength test and air tightness test?: All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed

Q:What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?: Adjust the speed of the water pump to adjust the flow of the most appropriate, such as liquid or variable frequency control, with the switch pump outlet door to adjust the flow rate is the most uneconomical.

Q:Where is the filling portion of the valve?: The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.
