Q:What type of flange does it fit with the gate valve?
According to the welding plate flange, flange material selection of piping material.
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
Water supply and drainage and civil air defense works, now with the dark rod type elastic sealing gate valve more.Compared to the gate and the traditional carve type or parallel double gate plate valve has the following characteristics: 1, soft sealing valve body, valve cover using precision casting foundry, a molding, no mechanical processing, do not use sealed copper ring, saving non-ferrous metals;
Q:Why does the centrifugal pump start and stop in the case of closing the gate valve?
The centrifugal pump starts and stops in the case of closing the pump outlet valve. Start off the pump outlet valve is to reduce the starting current, stop when the pump is closed, the outlet valve is to reduce water hammer, prevent blade from bad.
Q:What's the difference between a soft seal gate valve and a hard sealed gate valve?
The difference is that the form of the gate seal surface is different.General gate valves are generally leaking, easy to rust and other phenomena. Soft sealing gate valve (elastic seat sealing gate valve), gate material for cast iron lining rubber, overcome the shortcomings of the general gate valve, such as poor sealing, elastic fatigue, easy to rust, etc.. Soft sealing gate valve is a new product of the traditional gate valve.
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?
Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.
Q:What are the structural differences between parallel and wedge valves?
The advantages of dual gate plate is sealed and angle precision low temperature is not easy to make the wedge gate, the abrasion of the sealing surface and shim.The disadvantage is that the structure is complex, easy to stick in the dry medium, mainly the upper and lower baffles. After years of corrosion, the gate is easy to fall off. Although the single gate is sealed and angle accuracy requirements are relatively high, difficult processing and temperature change may make the gate wedge and other shortcomings, but has the advantages of simple structure, reliable use, especially to the flexible gate, can produce the micro elastic deformation to compensate for the deviation between the sealing surface angle processing, which is widely used at present.For more information about valves, please keep an eye on the valve knowledge section.
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 is an inverted seal gate valve?
It refers to the middle part of the valve sealing valve valve sealing surface, the valve cover has a sealing seat, which is the valve and stem as well as the joint of the valve rod and the valve cover (i.e. internal stuffing box at the bottom of a sealing structure).
Q:What's the difference between the knife gate valve and the stop valve?
Generally large and nominal caliber DN50 mostly with gate valve, especially industrial high temperature, high pressure, highly toxic and so on.Stop valve is able to stop and adjust flow, small footprint, small size, generally less than the nominal diameter, DN50 occasions use it. Two can be closed, in the flow of linear requirements are not high, you can adjust the flow. Just because of its structural characteristics of the valve to make its flow resistance, so there is a demand for throttling with a little more than the gate valve. In addition, the cut-off valve, whether it is a formal or reverse installed, in the opening and closing process, there is always a very difficult, and therefore can not do a great deal, or it is not easy to open and close. In addition, the cut-off valve has a one-way sealing effect of good features, so in the prevention of reverse flow of the working fluid, it also has a place to play.Hope to be of some help to you!
Q:What is the difference between the cut-off valve and the gate valve?
What is the difference between gate valve and stop valve?:Gate valve and globe valve structure is different, the valve structure for hand wheel, with the stem rotating together to do the opening and closing movement. Valve structure is rotating handwheel, stem do lifting movement. The flow is different, the gate valve requires full open or full closed state, the cut-off valve does not need. The valve has the flow direction requirements, and the gate valve has no inlet and outlet requirements!Sealing performance comparison:Valve length is shorter than the cut-off valve, higher than the cut-off valve, the valve should pay attention to the installation of high elevation. The gate valve can be tightly closed with the sealing surface by the pressure of the medium so as to achieve the effect of not leaking.
Products: the middle and low valves in accordance with the standards of GB, JIS, ANSI, DIN, BS, NF and casting products.The annual production volume: 80,000 tons of valves and 20,000 tons of auto parts.Credit: the credited company accredit by the Agricultural Bank of China and China Construction Bank, the grade of A enterprise by the Credit Management Division of Chinese Academy of International Trade and Economic Cooperation of the Ministry of Commerce PRC.
