Q:What does gate valve Z41H-40 mean?
40 kg flanged cast steel gate valve;Flanged gate valve, 40 pressure
Q:What are the differences between the gate valve and the cut-off valve?
The operating principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outletAt the same time, usually with the cut-off valve instead of gate valve, but the valve can also be used instead of cut-off valve. Valve sealing performance better, but the size is generally not large, the size of the gate valve can be done great.The main difference between them lies in:1, different structure, gate valve structure is more complex than the height, larger size, from the appearance point of view than the cut-off gate valve is short and high, especially the gate height space needs a higher open bar, the selection in the installation space under the condition of limited attention to.2, sealing surface, valve in the opening and closing valve and the valve seat surface always contact and friction between the sealing surface, and thus easy to wear, especially in close off the valve when the valve before and after the great pressure, sealing surface wear is more serious. And the valve once the valve is in open condition, it's seat and disc sealing surface between, not in contact,
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:Gate valve is gate valve, gate valve specifications, model code is generally what?
Gate valve is not gate valve, gate valve does not have a fixed specific model
Q:Gate valve DN65 what does that mean?
DN65 indicates that the valve bore is 65CM.The gate (gate valve) is a headstock ram, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed doors, discomfort pumpsparameters vary, usually 5 degrees is not high, medium temperature is 2 degrees 52'. To improve its manufacturability, make up for the deviation of the angle of the sealing surface during processing. This gate is called an elastic ram.
Q:What are the advantages and disadvantages of flat gate valves?
The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.
Q:What does valve qz45x - 10q mean?
Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
Q:What is a protective gate valve? What is gate valve knowledge?
it is up to the function of a single valve can not reach the exit of the product is installed in the water supply pipe and the head of civil air defense to conveying medium to stop, wave and wave combination, to prevent internal shock wave into the system engineering facilities, so as to eliminate the destructive shock wave, to protect the system facilities normal operation and safety protection purpose.
Q:What does Z941H-25DN250 mean by electric gate valve (excluding electric equipment)?
Cast steel flanged gate valve 25 pressure bore 250
Q:What's the difference between a soft seal gate valve and a hard sealed gate valve?
It uses the elastic material of the gate, and uses the elastic material to produce the micro deformation compensation effect. It can achieve good sealing effect. Soft sealing gate valve has the advantages of light switch, reliable sealing, good elasticity memory and long service life.Hard sealing surface of the gate valve for cast iron or stainless steel, open and close resistance is small, no flow, but poor sealing performance.
