Q:What's the size of the signal butterfly valve sleeve?
The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve.
Q:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
One is the turbine drive and the other is with the handle
Q:Butterfly valve structure and working principle
How it works: the disc is driven by the stem, and if it turns 90 degrees, it can be opened and closed once. By changing the deflection angle of the plate, the flow of the medium can be controlled. There are two kinds of butterfly valves commonly used: clip type butterfly valve and flanged butterfly valve.
Q:What's the material of the butterfly valve seat?
The seating material shall meet the following criteria:1) fluid compatibility, including expansion, hardness loss, permeability, and degradation;2) hardness;3) permanent deformation;4) the degree of recovery after load removal;5) pull in and compressive strength;6) deformation before fracture;7) modulus of elasticity.
Q:What does butterfly valve nps12cl150d373f4-150lb stand for?
NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
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: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:Butterfly valve model D344H and D343 difference
[2]: butterfly valve 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 the air water, steam, and 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.The answer is recommended by Gu Fengxiang, a member of the science education category
Q:D37A1X9-16CB1: what does this butterfly valve mean?
The model is composed of 7 units, the types of valves (gate valve Z, J, L, Q ball valve, throttle valve, check valve and H valve, butterfly valve, connection mode (D) internal thread 1 thread 2, welding flange 4, 6, 7, the clamp (0) electromagnetic transmission mode 1 solenoid valve, hydraulic, electric and hydraulic turbine are 2, 3, 4 and 5 gears, bevel gear, pneumatic hydraulic, 6, 7, 8, 9) pneumatic and hydraulic, electric, structure (straight or DC type 7,1 on behalf of the center plate, vertical type A (A) and LT X9) on behalf of a sealant is heat-resistant rubber, kg 16 kg, C represents the body material of carbon steel WCB, B1 on behalf of the valve plate is made of ductile cast iron plating)
Q:Fire signal butterfly valve what role?
Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points
