Q: Where is the Shandong valve? How about joint valves in Shandong?
To find Shandong valve manufacturers, Shandong better valve manufacturers are in Weifang, find the valve factory is also simple, direct search "Weifang valve" is
Q: I would like to ask, how specific treatment, and compared with the industry?.Is there a constructive answer?
I have some of them in the series of drawings.Build said veteran enterprises is the main power station valve company opened high pressure valve Wenzhou world Gansu Shenyang Nantong Shen Langao high power of Dalian is still high in alphabetical orderThe main floor is to engage in large high valve industry is a very good platform after the switch is convenient to say we all know whether peer or do
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: Hydrant valve leaks, how do you close other valves? Specific steps?
In construction, according to the design specifications, fire hydrant water supply pipe is an independent water supply system, and the water supply pipeline is separated from the water supply. In the trench into door position, need to set up a system of fire fire well, there are valves, only by finding the position of tube wells into households completed fire system diagram, in turn off the total valve can.
Q: Look at the flow chart, some of the valves are marked with FV, and some are marked with XV. What does that mean?And what do you mean by the Cv value on the valve nameplate?I hope the heroes give a clear explanation ah, it is best to give an introduction of this knowledge of the web site oh.Thank again.
Is the flow through the valve. That is to say, when the valve is fully open, flow through the valve size.
Q: What should be checked before using the valve?
5, check valve disc or spool movement is flexible and accurate, no bias, displacement or skew phenomenon6, spring-loaded safety valve should be sealed, positioning lever type safety valve should have the weight of the device7, rubber lining, lining enamel and plastic lined valve body surface should be smooth, the lining layer and the substrate firmly, no crack, blister defects, using high frequency electric spark generator to inspect the lining surface, not found in liner breakdown (white flash phenomenon) is qualified8, the valve flange sealing surface should meet the requirements, and shall not have radial scratches
Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?
High pressure bypass valve DN254 * 800 belongs to bypass valve.Function of bypass systemThe turbine by-pass device mainly has three functions of starting and overflowing:1 in the cold, warm and hot, the bypass system can realize the optimal unit start-up and shut-down in turbine operating conditions, start and stop curve can meet the requirements, two types of automatic and manual operation, with the establishment of the boiler steam temperature and steam turbine components. To shorten the start-up time.2. when the turbine is tripped, the bypass system can operate at a high speed and reach full open position.3., when the turbine load changes, the by-pass system has the regulating function, and the safety valve action can be avoided and the operation stability of the boiler can be improved when the instantaneous change of the moving state.The function of the bypass control valve:The main function of steam turbine bypass system is high pressure steam adjusting throttling and superheated steam cooling. The bypass valve to perform these functions at the same time and in low noise, small vibration, valve resistance to achieve its goal of temperature and pressure loss under the condition of touch.
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 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: What's the difference between a valve and a valve?
The valve does not have an Ethernet platform, and the "one" valve does not contain any other fittings.
