Q:What is the meaning of the D341*5-10 / 16ZB1 turbine butterfly valve flange said?
Liu1964tg, this guy is right, don't know, don't mislead everybody
Q:What is the difference between the installation and function of a butterfly valve and butterfly valve?
Therefore, the fully open position of the valve is determined by the position of the gate. Some gate valve, stem nut is located on the gate, the handwheel rotates to drive the stem to rotate, and make the gate lift, this kind of valve is called rotary bar gate valve, or call dark rod gate valve. The type of gate width, sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate type valve can be divided into: single gate type, dual gate plate and the flexible gate type; parallel gate type valve can be divided into single and dual gate gate plate. According to the thread position of the valve stem, can be divided into two kinds of open rod gate valve and dark rod gate valve. Valve installation and maintenance should pay attention to the following: hand wheel, handle and transmission mechanism are not allowed for lifting, and is strictly prohibited. Double gate valve should be installed vertically, that is, the valve stem is in a vertical position, and the handwheel is at the top. The gate valve with bypass valve shall be opened before opening to balance the pressure difference between inlet and outlet and reduce the opening force. The gate valve with drive mechanism is installed according to the instruction of the product instruction. If the valve is constantly switched on, lubricate it at least once a month. The valve has the advantages of small fluid resistance, the sealing surface by the erosion of small and medium Chong brush. Opening and closing is more labor-saving. Medium flow direction is unrestricted, no disturbance, no pressure reduction. The utility model has the advantages of simple shape, short structural length, good manufacturing technique and wide application range. Valve faults between the sealing surface can lead to erosion and abrasion, maintenance more difficult. Larger size, open need a certain space, long opening and closing time. Complex structure.
Q:What's the difference between an electric two position control valve and an electric butterfly valve?
With manual control device, once the power failure occurs, you can temporarily manually operated, and will not affect the use.The biggest difference is that the electric double bit butterfly valve can not fine adjustment; and the electric butterfly valve can play a regulating role.
Q:Is the pressure test of the centerline butterfly valve checked or checked?
The pressure test of the central butterfly valve is carried out at each station.Basis:1) GB/T12238-2008 flange and clamp connection elastic seal butterfly valveRules: butterfly valve must be carried out by factory inspection and testing, inspection qualified before leaving the factory.2) CJ/T 261-2007, butterfly valves for water supply and drainageRules: each product shall be inspected by factory and quality inspection department. After inspection, the product certificate shall be attached to the factory.Butterfly: also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.
Q:Is a valve adjustment necessary on my vulcan 500 motorcycle?
First off you are suppose to take your bike back to have your valves adjusted after 500 miles. Anything later can cause problems. The motor is already broken in. why did you wait so long to have them adjusted ? Your vibration is the tire is not balanced right , take it else where. good luck
Q:What type of valve does the butterfly valve D343X DN300 represent?
The GD343X model butterfly valve is the pipe flange butterfly valve. The J shaped elastic precision of the sealing ring and the three eccentric multi-level metal seal structure, is widely used in medium temperature less than 425 DEG C, petroleum chemical industry, metallurgy, electric power and water supply and drainage and municipal construction and other industrial pipelines, adjust the flux and set off fluid.
Q:Gate valve, butterfly valve and so on can do the valve so that?
Valve can not be used to adjust the use, if the switch can not be in place, the medium flushing gate valve is easy to cause poor sealing!
Q:Butterfly valve is the control valve?
The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
Q:whats the name of that valve under the kitchen sink?
Is the valve coming off a water supply line? if so, it's a needle valve probably installed at some point during a remodel or while adding an appliance. If it's on the cold side it will most likely go to a refrigerator ice maker or water dispenser, if it's on the hot side it may go to a dishwasher or other device that requires hot water.
Q:Do you use the straight stem butterfly valve in the fire fighting engineering?
Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
