Q:I would like to ask how to access the valve?
Valve range can be very wide, each company to do valve products are not the same;According to the company's production capacity and technology,Valve parameters to:1, valve spool material,2, connection mode (thread, welding, flange, clamp, socket welding, fast loading, etc.),3 caliber,4, medium (water, steam, oil, gas, liquid, etc.),5, temperature (medium temperature, environmental temperature),6, pressure (MPa, LB, K, etc.),7, configuration (executor and its accessories);A lot of valve requirements and this almost. Can also be selected according to the ideal valve function of customers.Switching type:Ball valve, butterfly valve, globe valve, gate valve, needle valve, etc.Regulatory type:Pneumatic valve, electric valve (adjustable type can be divided into: regulating temperature, regulating pressure, regulating flow), and so on
Q:What is the KVS in the valve parameter?
The valve Kvs is to reflect the passing capacity of the valve, which is defined as the pressure at both ends is 1bar, through the flow of the valve, Kvs is a characteristic parameter of the valve, and valve structure, is a constant value.
Q:Proportional valve why than other small pipeline valves
3.8 valveGraphical representation of numbers, names, symbols3.8.1 angle valve at room temperature3.8.2 cold angle valve for low temperature use3.8.3 stop valve at room temperature3.8.4 ball valve often 9 temperature3.8.5 valve at room temperature3.8.6 butterfly valve at room temperature3.8.7 check valve flow from blank triangle to non empty triangle3.8.8 pressure reducing valve, small triangle for high voltage end3.8.9 throttling valve is needle valve3.8.10 three-way valve for normal temperature use3.8.11 four way valve used at normal temperature3.8.12 safety valve spring type safety valve3.8.13 trap actual drawing, you do not have to draw arrows3.8.14 inflator, cold box, little gas huff and puff, safe useValve for normal temperature of regeneration valve of 3.8.15 reverse stop valve3.8.16 reverse loading cold angle valve
Q:Is there any difference between the valve and the water valve?
Oil valve with water valve is that the oil valve is over the oil, and the valve is over water, the type of fluid is not the same.Valve (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 does "TD671F" mean?
You should type is wrong, or I should be D671F, with very limited knowledge and scanty information, this type of mean (D) pneumatic butterfly valve (6) of the clip (7) sealed the middle (1) fluorine plastic (F). There should also be a number of pressure figures and body material. For example, D671F-10C later means that the pressure is 10 kilograms (or 1.0MPa) and C represents the carbon steel
Q:What are the technical requirements of valves, such as "Z15W-25T"?
Z = gate valve1 = internal thread connection5 = dark rod type (structural form)W = body seal payments25 = 2.5MPa (nominal pressure)T = copper (body material)Landlord can refer to JB/T 308-2004 valve model preparation methods
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:What does the valve QF mean?
Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
Q:What do letters represent in the QF-2 and PX-32 valve models?
Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
Q:Internal structure of valve
To answer your question was the top valve is not open on the thread of an analogy between ordinary wood screws and nails is a straight out of another can only rely on the screwdriver to turn out the cut-off valve is from the mechanical analysis of text as a specific principle is not specific
