Q: What is the main function of the valve?: Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.

Q: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?: The difference between the three is as follows: pneumatic valve]: driven by compressed air valve. Operation principle: the pneumatic control valve is composed of actuating mechanism and regulating mechanism. The actuating mechanism is a thrust component of the regulating valve, which generates the corresponding thrust according to the pressure of the control signal, and drives the regulating mechanism to move. The valve body is the regulating component of the pneumatic control valve. It contacts the regulating medium directly and regulates the flow of the fluid. [hydraulic valve]: the use of oil and other liquid pressure driven valve. The working principle of the hydraulic valve control valve pressure control valve flow control valve control valve control valve to control the direction of hydraulic system oil flow direction or liquid flow through the valve two, the working principle of the valve core and the valve body and valve off valve two-way hydraulic lock check valve to make oil movement off or on, changing the direction of the oil flow, so as to realize the hydraulic actuator and its driving mechanism of starting and stopping or changing the direction of movement. [electric valve]: with electric actuators to control the valve, so as to achieve the valve opening and closing. The utility model can be divided into two parts, the upper part of which is an electric executor, and the lower half of which is a valve. Also called air conditioning valve. The electric valve is usually connected by the electric actuator and the valve, and it becomes an electric valve after installation and debugging. The electric valve uses the electric energy as the power to switch on the electric actuator to drive the valve and realize the valve switching and regulating action. So as to achieve the purpose of switching or regulating the pipeline medium.

Q: What kind of valve is it? How do you see the status of the switch?: This is called gate valve. The core is opened and the core is screwed down. Turn left and right.

Q: According to the original valve installed on it, but never demolished, I am afraid to force over, will not be broken? The old valve, that part of the remaining three tubes tight.: 1. Prepare the glue and saw blade. Disengaging bracket.2, using a hand saw from the valve mouth (spool near) transverse incision.3, the center will be on the move, the longitudinal incision, be careful not to damage the inner tube.4. Clean the pipe mouth, pipe and new valve coating, install the valve.Turn left and turn right |

Q: Which valves are used in the power station?: Water supply system: butterfly valve, gate valve, eccentric hemisphere valveOil and gas system: stainless steel ball valve, stop valveFire fighting system: gate valve, relief valve, relief valve, sprinkler system

Q: Where is it installed, what is the role, what is the material, and are there other alternatives instead of this effect?: Valve packing in the valve under the gland to prevent leakage, you can use ordinary asbestos rope and butter emergency replacement

Q: 1. What does valve 13Cr&FHF mean? 2, valve WC6 (F11) what does that mean? 3. What does valve P280GH mean? 4. What does valve A335P22 mean?Thank you: The first seems to refer to the material inside the valve, containing Cr of 13% (equivalent to the 1Cr13 of our country), FHF=full face hardThe other refers to the body of the material, the corresponding standard forWC6=ASTM A217 WC6P280GH=EN10222 P280GHA335P22=ASTM A335 P22

Q: How can the material be checked by valve approach? What experiments do you need?: First of all, to check material certification, and secondly, the material appearance, shape and size of the initial test, again on the alloy material according to the standard spectrum analysis, the valve to do pressure test.

Q: How does the valve close?: Special wrench or socket.Turn clockwise to the end。The handle should be closed groove and the coincidence place.

Q: The low pressure in our factory is below 1.6Mpa, medium pressure is 2.5-6.4MPa, high pressure is 10-80MPa.Where's qusetion:1.6-2.5Mpa??? Which section does it belong to?. I think many of them are defined on the Internet But I didn't say, where's 6.4-10Mpa?: In fact, this is only the valve industry sector argument, not necessarily to distinguish between very clear.As long as the customer pressure requirements, we give him the drawings on it.Valve flange thickness and valve thickness are not standardized, according to pressure requirements.The flange thickness of 6.4Mpa and 10Mpa is completely different from that of valve body.For example: general gate valve, the most basic pressure 1.6MPa, according to GB/T139272008 and JB/T90921999 standard castingGenerally selected 1.6MPa, when the highest pressure pressure is 1.6X1.5=2.4MPa, if you exceed this pipeline pressure is not, there are now many manufacturers in order to save costs, the valve wall is thin, a conventional valve pressure 1.6MPa is a bit difficult.My own boundaryVacuum negative pressure 0.05Mpa-0.5Mpa0.6Mpa-1.6Mpa belongs to normal pressure (low pressure)2.5Mpa-4.0Mpa belongs to medium pressure6.4Mpa-10Mpa-16Mpa-25Mpa-32Mpa-42Mpa belongs to high pressure50Mpa-80Mpa belongs to supercritical high pressure valve
