Q:Butterfly valve, globe valve, ball valve used what is different: Butterfly valve, globe valve, ball valve used in different occasions:1. valve (Butterfly Butterfly) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.

Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?: 1, the valve body and the valve cover as a whole bear cavity, must meet the design manual on the minimum wall thickness requirements, at the same time to add corrosion allowance, at the same time calculation, large value as the wall thickness of 2, then according to the height of gate valve diameter, to ensure that the valve in the fully open under the condition, ensure the seal and the valve cover seal gate, so that we can determine the height of

Q:PPR gate valve, stop valve, dark valve, ball valve what is the difference between the gate valve and dark valve is a thing?: Dark valveThe blind valve is used to control the solar switch, and the double live ball valve connects the hot water pipe and the pipe, or the connection between the prefilter and the pipe, then it will be replaced in the future. The dark valve can be connected to the three pass.Globe valveBall valve (ball valve), standard GB/T21465-2008 "valve terminology" is defined as: "open and close parts (spheres) driven by the stem, and around the axis of the ball valve for rotation of the valve.". Can also be used to regulate and control fluid, strong shear force between the metal seat seal V type ball valve V type ball core and welding hard alloy, especially suitable for containing fibers, small solid particles and other media. Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. In accordance with the way to drive the ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve.

Q:What is a high handle ball valve? What's the difference between it and ordinary ball valve?: the valve handle can extend out of the insulation material, convenient operation.

Q:Is the ball valve switch in front of the water meter or after the water meter?: It's in front of the water meter. What's the problem?.

Q:Domestic water pipe ball valve or cut-off valve?: So, in the regular switch to the place, with the ball valve convenient, in the need to adjust the flow of the place and do not need to switch regularly, with a good cut-off valve.

Q:I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......: 2, shortcomings:Because the main valve seat seal material is PTFE, it has almost all the chemical substances are inert, and the friction coefficient is small, stable performance, easy to aging, temperature range and excellent sealing characteristics of a comprehensive. But the physical properties of PTFE include high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity. The design of seat seals must be carried out around these characteristics. Therefore, when the seal material hardens, the reliability of the seal will be damaged. What's more, polytetrafluoroethylene has a lower temperature range and can only be used at less than 180 degrees centigrade. Over this temperature, the sealing material will age. Consider long-term use, usually only at 120 degrees does not use.Its regulating performance is worse than the cut-off valve, especially pneumatic valve (or electric valve).Two, scope of application:Ball valves are used in petroleum refining, long distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.

Q:What's the difference between T ball valve and L ball valve?: This is the code for the three way ball valve and the three way plug valve flow passage. The L shape can only connect the two channels perpendicular to each other, and the T shape allows the three channels to communicate with each other or to connect two of them.

Q:What are the differences between the lever ball valve and the handwheel ball valve? What are their differences?: Group pairs of valves, have not heard of a lever type ball valve, only lever type safety valve, hand wheel type is only the way it drives different, the way is also ever-changing, to see the needs of individuals

Q:For the master enlighten Q47 ball seat spring hole number is determined by how: Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameterCalculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).
