Q: What are the working principles of the electric gate valve?: You see what type of electric valve, is integral or ordinary type, if the overall type Denso took power on the line, is generally 380V and 220V power supply, and then according to their own needs and then open the signal line, in place and closing in place and remote control line, valve position feedback signal 4~20ma over torque protection, fault signal. Ordinary type electric valve should be equipped with the control box, the motor is the true story and the inversion, and in general to a trip signal signal is normally open and normally closed, closed in place are normally open and normally closed two points according to their own needs wiring, three lines and then open and close control of the line of control there are also 4 lines to control some manufacturers, as well as the valve position, some three lines connected with the potentiometer, some installed valve position transmitter is connected with two lines, and over torque protection fault signal.

Q: What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve: Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.

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 /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: How about the model of stainless steel gate valve?: Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.

Q: Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?: In the standard JB/T5296-1991 "universal valve flow coefficient and the flow resistance coefficient test method",

Q: What does gate valve do?: Like other valves, the gate valve is used to block fluid flow. Is the gate valve 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.

Q: What's the difference between the knife gate valve and the stop valve?: Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.

Q: The valve safety valve check valve + + + = exposed part of a water pump adapter? Five: Generally do not require safety valve, just install exhaust valve in individual places.

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: Fire protection gate valve from the wall how many distance there is no regulation?: Don't know don't answer. "According to the provisions of article 6.2.13 GB50038-2005" code for design of basement for civil air defense engineering, into or through the door unit between the door closed wall should be set up in the inner side or two nominal pressure pipeline is not less than 1.0MPa, the spool is stainless steel or copper gate or globe valve water pipe from the air enclosure structure. The installation position from the wall should be not more than 200mm.
