Q:What domestic PPR ball valve can withstand acid and alkali?
Yue Yue PPR ball valve products are made of pure raw materials, mainly used in water supply and other plastic piping systems for industrial use. You can rest assured that the use of Hong Yue products
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.
Q:Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ
Stainless steel refers to the material composition, forged steel is a molding method. Not a concept.Stainless steel can be either a casting or a forging.
Q:A connection wire for 21mm the other end is connected to 4 points inside the pipe joint ball valve
Four is 1/2=DN15, 21mm data is not accurate, if it is metric thread, provide tooth pitch and thread diameter.
Q:What are the use of all - way ball valves and reducing ball valves respectively? What are the advantages?
But for the need for regular pigging of the pipeline, no matter what medium to transport, you must use full diameter ball valve.
Q:What do you mean by 266 in the 266 brass ball valve?
In order to consider the cost, some manufacturers put in different environment in accordance with the actual need in addition to the basic properties (such as gas safety requirements, key strength, air conditioning temperature, focus on material and penetration, ordinary water can have the basic properties, can economic production and product classification), but in the national standard of the same specifications or inside them the same type,
Q:What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?
I. structural form:The eccentric hemisphere valve is divided into two kinds in its appearance and structure:The coat type: mainly for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and cost.Side mounted: side mounted, compact structure, light quality valve, applicable to the valve installation space requirements.
Q:What's the meaning of the double ball valve in the double ball valve?
By means of "union", the "live" means that the two ends of the valve are connected by a live joint
Q:Hello, I would like to ask the household tap water valve selection of stainless steel ball valve or brass ball valve is better, thank you
I have used two kinds, but stainless steel gate valve is better. Note that it must be made of stainless steel 304. I bought more than 300 yuan a gate valve. Total valve, no way to save money.
Q:Structure design principle of fire ball valve
5 ball valve seat structure typical fire abroad professional production company common pipeline ball valve seat structure design of typical figure 9 - 12 shows, each seat structure fireproof structure design is reasonable, to ensure the seat piston effect of the sealing ring and the valve seat seal failure, valve seat leakage way at least. Figure 9 rubber sealing seat 1 to the left to the right in Figure 10 | rubber sealing seat 2 to the left to the right | Figure 11 rubber and plastic combined sealing seat to the left to the right in Figure 12 | plastic seat to the left to the right seat | fireproof structure design reasonable, can guarantee the way upstream pressure medium through the valve seat leakage at least fire, the best performance. In the design of fireproof structure of pipeline ball valve, the fire protection structure design of valve seat should be paid more attention to. The seat of fire with reasonable structure is the fundamental guarantee of fire safety in the pipeline valve in practical engineering, reasonable assessment of structural fire protection should be strictly in accordance with the API6FA/API607 standard fire test, test samples should not be sample makers, should be the verification institution with sampling, so as to ensure the rationality of the third party authentication and notarization of.
