2.Feature
1, the slip joint consists of ontology, the short tube, pressure and sealing ring, bolt and force of pressure.
2, general installation on the upstream side of the valve or other device. The slip joint for pipe flanges, upstream of downstream of valve. The slip joint force stud were deeper than the back of the companion flange, pipeline companion flange and valve through the nut, for the connection of tube and valve upstream and downstream equipment.
3, need to remove the valve, to force no lag bolt end flange pipe (side) of the nut loose behind the companion flange, then stretched to shorten the tube on the side of the nut to loosen the flange pipe direction. And then fixed through stud square head, rotate the nut on the reverse of the expansion pipe companion flange, make the move to the telescopic pipe flange pipe end. In the event of a reasonable interval can be removed after. Then unscrew all force stud on all nuts, make force bolt from one side to unload. Remove the valve.
- Q: Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!
- A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!
- Q: the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?
- Strength of the corresponding meaning is: the valve used to connect the original way of normal connection, such as silk mouth with the same specifications of the silk mouth connection. You can't connect the wires with different sizes.The pipe clamp is fixed in the counterpart application, from the interface at 200mm was measured with a ruler, when the nominal diameter is less than 100mm, the tolerance of sigma <1mm, when the nominal diameter is greater than 100mm, tolerance for a <2mm, but the length of tolerance is less than 10mm, no strong counterpart or eccentric pad counterpart.
- Q: What does "1/2" mean on the valve?
- 1/2 is 4 points (20), 3/4 is 6 points (25), and 1 is 1 inches (32)
- Q: 1/2, what does 1/4 valve mean? I don't understand. What does this number mean? Have a valve to introduce me, do not copy a pile of online introduction, I want to concise
- It should be said that the diameter is represented by units per inch! 15mm 6mm nominal diameter valves representing metric units!
- Q: What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
- The use of the same difference, you can see the shape
- Q: What items and detailed procedures should be inspected for valve size inspection?
- The American Standard (American Society of mechanical engineers ASME B 16.10-2000). Internet access can be downloaded, such as free standards to share and download sites. If you need any other valve standard, send me the mailbox.
- Q: How do you understand the valve Z41X-16?
- This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron
- Q: How to open the gas valve with drawings
- First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out.
- Q: Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you
- On the valve network to find the best, you can find the valve business in Anhui
- Q: How big valves are used in a DN159 pipe?
- DN159 is the valve with the DN150 in the outer diameter of the pipe.The valve size of the pipeline is classified by nominal diameter:1, the small diameter valve: nominal diameter DN = 40mm valve.2, medium diameter valve: nominal diameter DN from 50 to 300mm valve.3, chase diameter valve: nominal valve DN for 350 ~ 1200mm valve.4, large diameter valve: nominal diameter DN = 1400mm valve.The components of the valve must be handled following process before they are assembled:1, according to processing requirements, some parts need polishing, surface processing burr can not be;2. All parts are degreased;3, after degreasing, pickling and passivation, the cleaning agent does not contain phosphorus;4. After pickling, rinse with pure water, no residue of medicament, and carbon steel parts shall be omitted;5, one by one parts with non-woven fabrics dry, not cable, hair and other retained parts of the surface, or with clean nitrogen drying;6, with non-woven fabrics or precision filter paper, stained with pure alcohol, wipe parts by one, until there is no dirty color.
