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: 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: How to distinguish between gate valve and 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. 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.

Q: What's the difference between open rod gate and dark rod gate valve?: 3, dark rod valve is located inside of the body, in the process of opening and closing, stem only rotation move, the gate in the valve body lifting; the valve stem rod driven gate valve with the valve stem of the lifting drive thread in the external body, according to the direction of movement of the stem and the position of judge the gate opening and closing and position;

Q: Does the tap belong to a stop valve or a gate valve?: Most faucets are stop valves,Part of the faucet is plug valve,Hot water nozzles are almost all plug valves.

Q: The valve safety valve check valve + + + = exposed part of a water pump adapter? Five: There is integration now.Pump adapter SQ100. All contain.

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 is the gate valve for the DN65 hydrant?: DN65 hydrants are available with either DN65 gate valves or butterfly valves.

Q: What is the difference between the cut-off valve and the gate valve?: Selection of stop valve:There are two ways to install the valve, one is the media flow from the top of the spool, the advantage is that when the packing is not under pressure, the pressure can be replaced before the valve packing, there is a long service life characteristics. Another is the media from the bottom of the spool into, and its shortcomings are driving torque is large, is 1 times above the flow, the stem by the axial force of large, easy to bend the stem. Generally suitable for small caliber manual stop valve, to stop the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way.Selection of gate valve and stop valve:Valve than the valve structure is simple, better sealing, manufacturing and maintenance to be convenient; shortcomings are fluid resistance, power, and opening and closing efforts. Gate valve, stop valve are fully open, fully closed valve, suitable for making cut off, it is not suitable for use as regulating valve. The application process should pay attention to the characteristics of the valve when selecting. Small pipes and better sealing performance generally use cut-off valve; in the steam system and large diameter pipeline, due to fluid resistance is small, suitable for use gate valve.

Q: The legend of gate valve and stop valve: The working 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 outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
