Q:The difference between butterfly valve d71x_10s and d341s-10
Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
Q:What does butterfly valve do?
Butterfly valve (English: butterfly valve) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe 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. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve. Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.
Q:Buried extension butterfly valve is buried directly, or need to repair the valve well?
The establishment of a repair valve well, easy to repair, usually hydrogen long rod butterfly valve installed in the well. But if the quality of buying long stem butterfly valve, it can also be buried directly, not easy to bad
Q:What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?
Eccentric butterfly valve and ordinary butterfly valve, when the butterfly valve is opened, the eccentric butterfly valve sealing surface will reduce great wear, in the opening, the disc will leave the valve at the first time the sealing surface!
Q:Which is expensive, butterfly valve?
Gate valve and butterfly valve can not simply take the price there to compare, look at the actual design requirements of the project. General small caliber are selected by the valve, because of better sealing performance, service life is long, the maximum diameter of valve is usually choose to use the butterfly valve to the pipeline DN800800 above, because the valve is cheap, the price is only half of the large diameter valve. Also some pipes from the use of quality point of view, will choose the gate valve. How to use it, please mark the map
Q:What does "D41X-16" mean?
GB case, D is butterfly valve, 4 is flange connection, 1 refers to the midline structure, X is sealed form for three yuan, ethylene propylene rubber seal, and 16 is the pressure of 16 kg.
Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.
Q:How many kinds of butterfly valves are there?
What's the score?There are central butterfly valve, double eccentric butterfly valve, three eccentric butterfly valveAnd according to the materialAnd according to the way of connection
Q:The difference between vertical and horizontal butterfly valves in municipal water supply
Vertical and horizontal only installation directions and installation methods are different. Functionally, there is no difference.The main difference between the two methods of installation is that:1. horizontal can effectively avoid the high temperature radiation above the pipe. The disadvantage is that it takes up a lot of space.The advantage of the 2. vertical is that the occupation space is smaller, and it is easy to install. If the pipeline is higher, it is not convenient for maintenance.
Q:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
Signal butterfly valve is generally can achieve full clearance of a valve opening electrical signal output, the general requirements of the electrical signal isPassive electric shock signals are mostly used in fire fighting systems, such as the need for valve position feedback;The electric butterfly valve is not necessarily the signal butterfly valve, because the electric butterfly valve does not have the requirement of the source contact.
