Q:Electric ball valve installation need to pay attention to what?
8, electric and pneumatic valve in order that no special contract allows only vertically installed in the indoor use. 9, after the completion of the pipeline construction, all the valves on the pipeline line shall be opened and the residual dirt shall be removed.
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 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:Ball valve leakage of this place, how do?
Ball valve can be closed on both sides, change to the other side closed, try, and if the water is still leaking, the middle of the core screw is prohibited,
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:PPR ball valve diameter is 3 cm, what is the specifications?
The PPR32 ball valve with the DN25 is a specification. (DN25 is the nominal diameter of the pipe and PPR32 is the outer diameter of the pipe)The PPR25 ball valve with the DN20 is a specification.
Q:What's the difference between air valves, butterfly valves and ball valves?
On the pipeline, mainly from cutting 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.Ball valve: opening and closing parts (sphere) driven by the stem, and around the square ball valve for the axis of the rotating valve.Shanghai Guardian valve, all types of valves are industry-leading.
Q:How much pressure can the flange ball valve withstand?
How many can, each kind of pressure specification has the different material quality, the thickness request, the ball valve can also use in the high pressure class.
Q:What is an eccentric hemispherical valve? How do you understand?
The eccentric hemisphere valve and the flange gate valve belong to the same type of valve. The difference is that the closing piece is a sphere, and the ball rotates around the center of the valve body to open and close a valve.
Q:What is the difference between ball valve and butterfly valve?
The ball valve and butterfly valve butterfly valve ball valve and the maximum difference between the difference between the two is the valve opening and closing parts is a panel, which is a ball valve, butterfly valve plate and the ball valve is rotated around its own axis for movement of the ball valve is a spherical sealing surface.The valve (Valve) is a mechanical device that controls the flow, flow, pressure, temperature, etc. of a fluid medium. The valve is the basic component of the piping system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
