Q:Fire protection gate valve from the wall how many distance there is no regulation?
1 meters away from the wall, leaving the maintenance and replacement distance
Q:What are the meaning of the cast rigid gate valves z41h-16c?
According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel
Q:What are the differences between the gate valve and the cut-off valve?
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, is not suitable for regulation and throttle. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used wedge gate valves form a wedge. The wedge angle varies with valve parameters, usually 5o. 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. Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.A stop valve is a valve that closes the valve and moves along the center line of the valve seat. According to this form of valve movement, the valve seat opening change is proportional to the valve stroke. Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. As a result, this type of valve is ideal for use as a shut-off or regulator and throttling
Q:Is the axial force and torque of the wedge gate valve the same?
B higher temperature. C nice wedge single gate valve is suitable for high temperature medium easy to coking. Flexible gate valve features: high temperature, a wedge type single gate valve in a special form. Comparison with wedge gate valve.
Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.
Q:What's the meaning of flexible z45x-10q door valve?
Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve
Q:What are the working principles of the electric gate valve?
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:Function of gate valve
Gate valve is a closed (gate) along the central line of the vertical direction of the valve moving. Valve in the pipeline can only be fully open and fully closed off, can not be adjusted and the throttle. Gate valve is a valve used in a wide range, generally more than 50mm caliber DN block device is selected it, sometimes cut off very small aperture devices are used to gate valve, gate valve is used as cut-off media, when in full flow through the whole, when the media is running a minimal pressure loss. Gate valves are normally used in situations where they do not need to be frequently opened and closed, and the gate is fully open or fully closed. Not used as an adjustment or throttling. For high speed moving medium, the gate can cause the vibration of the gate under the condition of partial opening, and the vibration may damage the sealing surface of the gate and the valve seat, while throttling will cause the gate to suffer the erosion of medium.
Q:What kind of gate valve is Z6CS-H102?
Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
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.
