Q:Automatic exhaust valve installed in the pipe before and after the installation of other valves need to press it?
In general, the exhaust valve (large diameter) and a maintenance valve, normally open,
Q:What is a hot melt valve?
The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.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. 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:Our company is doing valve exports,
First of all, you have to check the HS encoding of your product.The corresponding HS code will have a regulatory condition followed by different regulatory conditions that mean different procedures (or certificates), such as what you call "B".What aspects must be examined in commodity inspection?Different products to implement different inspection and quarantine methods, the general is to do a customs clearance on the OK. The products you mentioned above may not need to do customs clearance (see what kind of valve you are, so you'd better check the conditions again)Is commodity inspection agent or business enterprise? Do you need to check every export?Generally not many agents are on the line, and if the HS regulatory conditions have to do customs clearance, then each time to do.Is there any standard or basis for inspection? Where can I find out the knowledge in this area?
Q:Which industries need valves?
3., the other side of energy development is energy conservation, so from the perspective of energy conservation, it is necessary to develop steam traps, and to sub critical and supercritical high parameter development;4., the construction of power stations to large-scale development, so the use of large diameter and high pressure safety valve and relief valve, but also need to quickly open and close the valve;5., for the needs of complete sets of projects, the supply of valves from a single species to more varieties and specifications. The valve required for an engineering project is growing with the full availability of a valve manufacturer.In the next few years, the overall trend in demand for the valve for the upward trend, the valve of this large volume of industrial supplies, its demand in steady growth. Among them, the demand for a larger number of valves in turn are: ball valve (15.5%), cut-off valve (12.9%), safety valve (12.5%), gate valve (12.5%), butterfly valve (10.6%), regulating valve (8%) and check valve (6.1%).
Q:How many triangular valves and other valves are used in kitchen and toilet decoration?
Generally, a toilet needs 5-6 triangle valves, namely: 1 under the toilet, 2 on the shower, 1 water inlet, 2 under the sink, and two in the kitchen sink.
Q:What does valve 41F-40C mean?
Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C
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:Is the heat jacketed valve fitted with flanged flanges?
Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.
Q:Is there any problem with connecting the geothermal valves with other geothermal pipes?
Material is the same, the fuse will not cause shrinkage when you can use
Q:How to quickly identify the types of valves?
You can look through shapes, signs, or buy a valve manual
