Q:Why can't the clip type check valve be directly connected with the pipe mouth or other valves?
The clip type check valve is made up of two discs to prevent backflow.If the clip check valve is connected to the other valve, the disc may touch the valve and cause the check valve not to be fully opened or closed. This is a preliminary analysis of "enter the valve", for reference only!
Q:Heating pipes, in addition to the living room,
1, whether the pipeline is too long, 2; block 3; distance is 4; water pressure is not enough 5; pipeline laying problems
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
Q:Valve category can fill the trunk door, branch valve Mody?
Each of these types of valves have very different varieties, such as the valve can be divided into: self sealing valve, knife gate valve, gate valve, cryogenic insulation jacket valve, seal valve, vacuum valve, flexible valve seat seal, valve, gate valve, signal buried forged steel gate, cast iron gate valve and so on.
Q:How many kinds of valves are there in the water pipes?
Valve is used as cut-off media, the flow through the fully open, then the pressure medium to run minimal loss. Usually does not require frequent valve for opening and closing, and maintain the gate fully open or fully closed condition. Not suitable for use as a regulator or throttle. For high-speed flow of medium, the gate conditions can cause vibration of the gate in the partial opening, and the vibration may damage gate and valve seat sealing surface, and the throttle gate will suffer erosion media. From the structural form, the main difference is that the sealing elements form. According to the form of seals, often divided into several different types of valve, such as: wedge gate valves parallel gate valve, parallel gate valve, wedge gate valve. The most commonly used form of wedge gate valve and parallel valve
Q:What valve is the DN 25?
That is, the inner diameter of the valve is 25 millimeters
Q:What does "TD671F" mean?
TD671F is pneumatic clamp type soft sealing butterfly valveValve (Famen) 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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q:What do you mean by the 16 bit coding of the valve type?
Valve model is by the type of valve, valve drive, valve connection, valve structure, sealing material, valve body material code to indicate.1. Valve types are Z- gate valve, P- drain valve, Q- ball valve, D- butterfly valve, J- stop valve, etc.;2, the valve drive mode code by letters said, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out3, the valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, valve structure code, for example: 0- 1- flexible gate valve, open bar wedge type single gate, 2- rising stem wedge gate, 3- parallel single gate, 4- double disk parallel, 5- dark pole single wedge gate, 6- dark bar wedge gate, dark 7- parallel single gate, 9- dark pole parallel gate;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber lining, Monel M-;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.
Q:Where is the Hefei valve market?
On the valve network to find the best, you can find the valve business in Anhui
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
