- Q: Replacement method of PPR hot melt ball valve
- 2, if the valve is directly welded on the pipeline, you need to stop the operation of pipeline, and cutting, the need to replace the valve flange or screw type ball valve, ball valve flange need two "steel plastic adapter" heat welding with the original pipe, the flange type ball valve can be installed; the screw type two single head, a head and pipe welding / bonding, joint head and ball valve with wire of threaded connection.
- Q: 1 and 1/2 ball valve is how much?
- 1 and 1/2 ball valves, DN40mm.The ball (ball valve as the cut-off valve in the marine and marine field), standard GB/T21465-2008 "valve terminology" is defined as: opening and closing parts (ball) driven by the stem, and around the valve axis 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 are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
- Pneumatic angle seat valve is the use of reciprocating actuators, usually in use to withstand fluid work pressure at 1.6MPa. Pneumatic ball valve is to use rotary actuator, to bear high fluid pressure. In normal use, the reciprocating actuator is characterized by its service life over the length of the rotary actuator. Two: easy maintenance. Three: the price is cheap. Personal recommendations in fluid pressure below 1.6MPa, or pneumatic angle seat valve is better?. High pressure, less opening frequency, pneumatic ball valve is appropriate.
- Q: All inclusive ball valve and half a bag of the difference between the ball, mainly new manual ball valve
- CharacteristicFirst, wear-resisting; because the hard sealing ball valve spool is alloy steel spray welding, sealing ring is alloy steel surfacing, so hard sealing ball valve in the switch will not cause too much wear and tear. (its coefficient of hardness is 65-70)Two, good sealing performance; because the hard sealing ball valve sealing is artificial grinding, until the valve core and the sealing ring completely in conformity with the use. So his sealing performance is reliable.Three, switch light; because the hard sealing ball valve sealing ring at the bottom of the spring, so that the sealing ring and valve tightly held together, so when the outside force exceeds the preload of the spring, the switch is very light.Four, long service life: has been widely used in petroleum, chemical, power generation, paper making, atomic energy, aviation, rockets and other departments, as well as people's daily life.
- Q: Hard sealing ball valve, what method can calculate the leakage? How much is grade 4? How much is grade 5? How much is level 6? For example: how many DN150 seals are 5 ml?
- Valve leakage level is used as an important reference standard in valve leakage test.Usually in accordance with the requirements of the process. In the process of lifting the conditions and processes, there will be valve leakage level requirements.
- Q: What is the difference between ball valve Q41F-16C and Q41F-16P?
- Q41F-16C ball valve material is carbon steel, Q41F-16P material is 304. No difference between the others. I hope you'll be satisfied.
- Q: What q25r-j159 BB-F-TE-NB represents American Standard ball?
- Each letter has different meanings. Such as model, connection mode, material, driving mode, etc.%021 $3461#$%9331^^ hope Shanghai Yiling valve to help you answer
- Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?
- 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: Switch valve type, switch valve, ball valve or butterfly valve is good
- Ball valve and butterfly valveBall valve is 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.Butterfly valve, also known as shutter valve, can be used to control the air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. On the pipeline, mainly from cutting and throttling.
- 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.
