- Q: How to solve the leakage of the valve stem of electric control valve?
- Answer: electric valve stem is sheathed at the Water Leakage, generally speaking is the stem seal screw inside the supporting body for long time working in sealing pads wear out so that the sealing mat does not play a sealing effect, will produce Water Leakage phenomenon. The solution to this problem can only change the set of sealed cushion, to ensure the normal operation of the electric control valve.
- Q: Stem material
- 3, alloy steelGenerally choose 40Cr, 38CrMoA1A, 20CrMo1V1A and other materials. 40Cr after chrome treatment, apply to nominal pressure is less than 32MPa, temperature less than 450 degrees of water, steam, oil and other media. 38CrMoA1A after nitriding treatment, can work temperature of 540 degrees under the pressure of 10MPa, often used in power plant valve. 20CrMo1V1A after nitriding treatment, can work at 570 degrees temperature under the pressure of 14MPa, often used in power plants valve.4,Generally choose 2Cr13, 3Cr13, 1Cr17Ni2, 1Cr18Ni12Mo2Ti and other materials. 2Cr13, 3Cr13 stainless steel for nominal pressure less than 32MPa, the temperature is less than or equal to 450 degrees of water, steam and weak corrosive medium, can be chromium plating, high frequency hardening and other methods to strengthen the surface. 1Cr17Ni2 stainless steel valves and cryogenic valves are resistant to corrosive media. 1Cr18Ni9Ti, 1Cr18Ni12Mo2Ti stainless acid resistant steel for nominal pressure less than 6.4MPa, temperature is less than or equal to 600 degrees of high temperature valve, can also be used for temperature less than -100 degrees of stainless steel valve, low temperature valve. 1Cr18Ni9Ti can resist corrosive medium such as nitric acid; 1Cr18Ni12Mo2Ti can resist corrosive medium such as acetic acid. When 1Cr18Ni9Ti and 1Cr18Ni12Mo2Ti are used in high temperature valves, nitriding treatment can be adopted to improve the scratch resistance.
- Q: and the valve core hole is provided with a guide hole and a valve stem to match. How to ensure the concentricity and convenient disassembly and assembly
- To ensure the concentricity of the spool and the valve stem is mainly two parts machining process properly, the valve stem threads and coaxial rod part of a good reference A spool cylindrical and a clamping hole must be processed, ensure the inner hole and reference A coaxial, so as to ensure the valve core and the the stem of the coaxial, burr thread when machining with a scraper or small file carefully.
- Q: What is the difference between them in use?
- In the soft sealing butterfly valve, no pin valve shaft, there are two main ways of connection: 1, through the shaft without pin, 2, double shaft without pin, through the shaft without pin, in the design is the most basic method, design simple. When the shaft is machined, the double half shaft has a certain degree of difficulty in making it.
- Q: What do you pay attention to in winter?
- The stem is more and more popular fishing friends, especially can often make us get a lot of surprises in the winter the stem, but many people still do not know how to operate the stem, here we give a simple introduction.What is a raft pole?Raft pole as a fishing rod is in fishing rafts, is inserted type fishing rod, generally 1.8 meters 2.1 meters, two, two, 2.7 meters 3 models, wire ring has dense and compact assembly of rod, a fishing rod handle fixing seat can be installed in different size type reel. The poles of a raft are usually made of glass fiber, characterized by fine, light, soft, good elasticity, and a variety of colors between the wires. Rod tip the subtle wind pull the line, the line will be able to shoot tip bending down, a burst of wind blowing, the rod tip frequently bent, like a fish bait fishing, careful to distinguish between wind scraping and fish bait is different. But it is raft of fine, sensitive, is the essence of winter fishing crucian carp. Less than one or two of small carp bait, raft pole pole will have obvious "action", easy to observe. Don't look at the raft rod rod tip very soft, but the rod handle extremely tough, skilled master that can be thrown thirty or forty meters may be nothing difficult.
- Q: What are the meaning of the LH for the size of the valve stem of the electric gate valve?
- Valve in general, into a positive and negative thread structure, to prevent thread loosening.
- Q: This summer, preparing to go on holiday to the seaside, of course, with fishing gear, I have 2.1 meters stem rod, a little hard, I would like to ask to sub bar road? I've never been cross, and if I can, what fake bait with sequins? How many grams, by the way, the fishing hook with what bait?
- I use sea worm, catch fish from the beach, shrimp meat and so on. Fishing play much, is keen to freshwater fishing, please answer the following.
- Q: Natural gas, oil or steam suitable for valves, valve stem, respectively, what is the material?
- If it is ball valve, ball with A105 plating ENP.Of course, all stainless steel 304316 is better, but the price is high
- Q: Hydraulic manifold valve, stem movement is a positive cover, what is the role?
- The spool is covered, in the middle, P mouth is closedThe manifold valves do not work together at the same time. T
- Q: How to catch carp reservoir spring stem
- Fishing for carp generally HaiGan, large float and special silver carp hook fishing float, at a depth of 1.5 meters.
