Q:What does gate z41t-10 150 mean?
According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
Q:The difference between flanged gate valve and common gate valve
Flange valve: English name; Flange Gate Valve is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.Ordinary gate valve: mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Gate valve applies to pressure, temperature and caliber range is great, especially for medium, large diameter pipesThe most important difference: flange gate valve and ordinary gate valve is different, flange gate valve quality, durable, easy to install, but higher prices, generally used for large pipelines. Ordinary gate valves are used for small caliber, easy to change places.
Q:Is the gate valve clockwise or closed?
In general, the valve is clockwise to turn off. Some of the clockwise rotation of the valve on the move is open
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
3, soft sealing rubber lining valve plate size uniform, interchangeable. Therefore, the soft sealing gate valve will be the direction of development, but also the water supply industry is willing to adopt a valve.
Q:What is the difference between Z41X gate valve and Z45X gate valve?
There is no difference in function. The two models are mainly made of different sealing materials,
Q:What does gate valve Z44T-10-200 code mean?
The meaning of the model is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionHttp://wenku.baidu.com/view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200
Q:What is an inverted seal gate valve?
When the inverted sealing gate valve is fully opened, the sealing of the sealing is brought together, and the sealing effect is reduced, and the erosion of the filling to the fluid is reduced, and the service life of the filler is prolonged, and the possibility of leakage is reduced. Generally on the gate valve, stop valve has inverted sealing requirements.
Q:What is the Z15T-16C letter of the gate valve?
The Z class code indicates the type of gate valve, gate valve is the first letter of the alphabet. The gate is manual driving mode, 1 said the connection form of gate valve for connecting thread, 5 represents the structure form of gate valve for rigid single gate, T gate said lining material of copper alloy, 16 PN1.6MPa nominal pressure valve. C said the valve body material is carbon steel.
Q:Gate valve Z41H-16Q generally used for what place?
Commonly used in petroleum, chemical systems, especially in long-distance pipelines of petroleum and natural gas.
Q:Is the gate valve flanged?
The most commonly used gate valves are threaded connections, flanged connections, and welded connections.Like the outer thread connection, the clamp connection, the card sleeve is seldom used.
