- Q: All inclusive ball valve and half a bag of the difference between the ball, mainly new manual ball valve
- Only know global valve and hemisphere valve, all inclusive Half pack? I don't seem to have heard of it. Discuss the problem in detail and see if you can explain it.
- Q: The working principle of the track type ball valve
- No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.
- Q: What is the maximum temperature resistance of the 304 stainless steel ball valve?
- What seal do you have?.PTFE sealing maximum temperature: 120 degreesMetal seal maximum temperature: 325-400 degrees, look at the manufacturers.
- Q: What is the difference between ball valve and butterfly valve?
- The two kinds of valves can be distinguished from their names. Ball valve cut-off is a ball in the valve to achieve, the ball blocked the pipeline will not flow, move away on the circulation. The closing effect of the butterfly valve is two or one butterfly wing, just like butterfly wings, or, like a blade, the shop is expanded and sealed, and the pipe is out of circulation. Plainly, one is blocking with the ball, and the other is blocking with the blade.
- Q: And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?
- When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body
- Q: One stainless steel ball, two pieces, three pieces of difference, use
- Structural features of two piece ball valve:1, opening and closing without friction. This function completely solve the traditional valve because of the friction between the sealing surface and affect the sealing problem.2, top structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.3, single seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.4 、 low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.5 wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.6. Self-cleaning structure of sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.
- Q: Calculation formula of ball valve flow
- Q=Cd*A* (2*delta_P/rou) ^0.5Among them, Cd is the flow coefficient, generally take 0.6~0.8, you can go to check informationA is the opening areaDelta_P is the differential pressure between the inlet and outlet of the ball valveRou is the density of the fluid
- Q: Stainless steel ball valve, Q11F-10P, 16P, 11F, what does that mean?
- The first 1 that connect the second ball, 1 straight through valve, F PTFE sealing.
- Q: Ball valve use?
- Ball valves are widely used in petroleum refining, long-distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, and play a decisive role in the national economy.
- Q: What's the difference between a hot melt ball valve and a ball valve in general? What's the use of it?
- Ball valve (in the field of marine engineering and ships should be cut-off 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 to rotate the valve movement.". 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.Ball valve was introduced in 1950s, with the rapid development of science and technology, production process and product structure of continuous improvement, in a short span of 40 years, has rapidly developed into a major valve category. In western developed countries, the use of ball valves is increasing year by year.
