Q:The difference between ball valve Q341F and Q347F
Ball valves Q341F and Q347F are turbine driven soft sealing flange ball valve, Q341F is a fixed ball valve, Q347F is a floating ball valve
Q:DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
3, the flange of the same caliber and cavity size, the premise is to ensure the gate open without collision resistance, but the size and thickness of screw and the number can be determined with reference to the parameters of the same diameter flange. Finally, the point is that in mechanical design, as long as the design is reasonable, there is nothing right or wrong, but it is possible that a design will be more appropriate.
Q:Advantages and disadvantages of ball valves and scope of application?
Ball valve and valve are generally used for fluid switching and flow, usually can not be used for flow regulation, and in addition to the valve can be used for fluid switching and cut-off, can also be used for flow regulation. If you need to adjust the flow rate, it is better to use the medium valve. The valve operation is very convenient, rapid and labor-saving, generally as long as the valve handle can turn 90 degrees, and the ball can be used not too pure (solid particles) fluid because of its spherical valve core of the fluid in the opening and closing of the shear movement. The gate seal between easy to cause erosion and abrasions, maintenance more difficult, larger size, open need a certain space, opening and closing time is long, complex structure.As you say, the ball valve is generally used for small caliber, because small caliber production is simple, relatively inexpensive, caliber increased production accuracy requirements, production costs increased, so the price will be high. Generally small diameter threaded connections, from the G1/4~G2 have.
Q:Family aluminum tube ball valve, with a long handle so that, or butterfly shaped handle so that?
Butterfly type unused, a long handle used, the quality is very good.
Q:What does "DN PN" mean?
Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of universal caliber. The pipes with the same nominal diameter can be connected with each other, so they are interchangeable. It is not the actual diameter or diameter of the pipe, although its value is close to or equal to the diameter of the pipe.In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.Nominal outer diameter is expressed by DN, refers to the outer diameter of the pipe. Such as the outer diameter of 32mm PVC-U pipe can be expressed as dn32. The specification of PVC-U pipe for building drainage is indicated by DN (nominal outer diameter) * e (pipe wall thickness) (GB-T, 5836.1-2006).
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:How can a steel ball in a steel ball valve be put in?
This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.
Q:Advantages of track ball valves
10, the valve refractory design, API, 6FA and API 607 standards. All valves are fire resistant and safe.The valve seat sealing surface., all metal seal structure, when the fire, still can guarantee the sealing medium leakage, stop.The flange. In stainless steel and graphite gasket, can meet the requirements of fire;The stuffing box is arranged. Flexible graphite packing, can lose the effect due to fire and other reasons in other packing flexible graphite packing to seal effect can meet the requirements of fire;11, the valve stem through the stem nut, valve cover, valve body, between the core of the ball formed a continuous circuit conduction, to achieve anti-static effect.12, in order to improve the reliability of the valve, safety and sealing capacity, to reduce the failure rate, the valve low-pressure air tightness does not depend on the seat spring to achieve.13, the stem and valve ball position by stem guide pin and stem to cut off the coordination to control, in order to ensure the stability of valve operation, stem guide pin for double guide pin, and stem guide pin can be removed and replaced from the outside.14, hand wheel or bearing fixed, use bolt or nut compression, do not use elastic clasp.15, the valve installation size and the existing valve consistent, with good interchangeability.
Q:Advantages and disadvantages of electromagnetic valve and electric ball valve
I think you should use the solenoid valve is diaphragm type, and not particularly good products, diaphragm solenoid valve in the closed position when the diaphragm is easy to change, resulting in pipe die, or medium impurities caused the pilot hole is blocked, the valve will not move, so the diaphragm solenoid valve. Is there a film guide card member, so that each position of the diaphragm in the correct position, but the pilot hole is not a solution, of course, you can use direct action solenoid valve, such problems are solved. The electric ball valve than the pilot solenoid valve in this respect, but the cost of this fear is much higher, especially the pipe diameter is not so, it does not pay!
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.
