Q:How to check the quality of the valve?
First of all, to check the appearance of the valve is smooth and smooth. Cast valves without sand holes and obvious flaws. Forged valves check nominal pressure or pound level.Second, check the material of the valve, that is, the material composition, this is very important, the material does not meet the standard on the device will be a big problem.Finally, check that the switch is sensitive and the signs are clear. Test pressure is the last step.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:Signal butterfly valve installation or other valve installation
The installation of the signal valve is in accordance with GB50261-2005The 5.4.6 signal valve shall be installed on the pipe in front of the flow indicator, and shall not be less than 300mm from the flow indicator.The other valve control valve installation, specification, type and location of installation shall comply with the design requirements, the installation direction should be correct, control valve should be clean, no blockage, no leakage; the main control valve should be added headstock logo, the control valve cover shall be provided to indicate position of the mark in the position.1. The installation of the exhaust valve shall be carried out after the pressure test and the flushing of the system pipe. The exhaust valve shall be installed at the top of the water distribution dry pipe and the end of the distribution pipe, and no leakage shall be ensured.2, the valve flow direction should be consistent with the direction of flow in the water supply pipe, water inlet side of the filter is installed, and should be installed in the control valve; the adjustable valve should be installed horizontally, the valve cover should be upward; the proportional valve should be installed vertically: when the level of installation, the valve orifice hole single breath we should double down, breathing valve whose orifice should be in a horizontal position.3 other control valve should be installed to keep a certain distance, to facilitate maintenance and management, installation of multifunctional pump control valve itself with pressure gauge, pressure gauge should be installed in the adjacent parts; import should be prevented in the back before the installation or use of the filter with filter backflow preventer, backflow preventer at both ends the valve should be installed separately, and at least one end of the flexible joint should be installed;
Q:Our company is doing valve exports,
If the customs clearance order is required, the boxes, invoices, and contracts will not be needed. If the customs clearance is made, which port should be provided, the value of the goods, the weight, and the HS code for those
Q:Is the filter also valve?
Classification, filter does not belong to the valve filter is indispensable to a device on the pipe conveying medium, usually installed in the valve, pressure relief valve, inlet water valves or other equipment end, used to remove impurities in the medium, to protect the normal use of valves and equipment. When the fluid enters the filter cartridge has a certain size, the impurities are blocked, and clean filtrate from the filter outlet, when cleaning, as long as the removable cartridge is removed, you can reload after treatment, therefore, maintenance is extremely easy to use.
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:What are the main equipments for valve production?
Press machine, CNC lathe, instrument lathe, drilling machine, machining center, assembly line, pressure test bench, plane, measuring instruments, etc.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 is the KVS in the valve parameter?
The Kvs of the valve reflects the passing capacity of the valve
Q:What is the flow medium of the valve?
Just like the one in your bottle, then the medium in your bottle is water
Q:What are the general types of valves?
Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion. In addition to the cylinder or hydraulic cylinder piston to drive, but also the use of pneumatic film driven, because of its small stroke and driving force, it is mainly used for regulating valves.Manual valveThe manual valve is the most basic way of driving the valve. The utility model comprises a hand wheel, a handle or a plate hand, and is driven directly and driven by a transmission mechanism two kinds. When the starting torque of the valve is large, it can be driven by gear or worm gear to achieve the purpose of omitting. Gear drive, spur gear drive and bevel gear drive. Gear reduction ratio is small, suitable for gate valve and stop valve, worm gear drive is relatively slow, suitable for cock flashing, ball valve and butterfly valve
Q:What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,
