Q:What is gate valve (with force transfer joint)?
The force transfer joint is mainly used for the loose connection of pumps, valves and other accessories.
Q:Gate valve z11h/y-16 what does that mean?
Product Name: internal thread gate valveItem number: Z11HProduct specification: DN15-50Product pressure: 1.6MPa-2.5MPaMaterial: cast iron, cast steel, stainless steelInternal thread gate valve nominal pressure 2.5Mpa, applicable temperature range -20-232-350, applicable medium: water, oil, gas and certain corrosive liquid (W.O.G), thread type G.NPT.BSPT.BSP.DIN259/2999.
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 do gates, Z15T-10, Z15W-16T, Z45T/W-10, Z41T-10 mean?
Z15T stands for manual, internal thread connection, dark wedge single gate. The sealing surface is made of copper alloy. The nominal pressure is PN1MPa;Z15W-16T for manual, internal thread connection, dark wedge type single gate, the valve body material is copper alloy, the valve seat sealing surface material directly processed by the valve body, nominal pressure is PN1.6MPa;Z45T/W-10 stands for manual, flange connection, dark wedge single gate. The valve body is made of copper alloy, and the valve seat face material is directly machined by the valve body. The nominal pressure is PN1MPa;Z41T-10 stands for manual, flange connections, plain wedge single gate, sealing surface material is copper alloy, nominal pressure is PN1MPa.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate
Q:The difference between gate valve and butterfly valve, as well as cut-off valve,
The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
Q:The difference between flanged gate valve and common gate valve
General diameter of more than 50 with flanges, inspection wells, main pipes, trenches... Must use flange gate valve, good operation, good replacement.
Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?
3, protective valve should be used for stainless steel or copper gate valve or cut-off valve;4, air defense enclosure structure, the distance from the proximal end of the valve should not be greater than 200mm. Valve should have obvious signs of opening and closing.
Q:Function of gate 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, can not be adjusted and the throttle.
Q:What is the difference between gate valve Z41T and Z45T?
Valve Z41T and Z45T difference is that "41" is dark rod, that is, the screw is not out of the turbine,"45" is the bright rod, that is, the screw out of the turbine.Common points are copper sealed gate valves.
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.
