Q:Daily maintenance of ball valve
Longer service life and maintenance free period will depend on several factors: normal working conditions, maintaining a consistent temperature / pressure ratio, and reasonable corrosion dataBall valve in the closed state, there is still pressure fluid inside the valve bodyRemove the line pressure before servicing and leave the valve in the open positionDisconnect the power or air supply before servicingBefore the maintenance, remove the actuating mechanism from the bracketMust be found on the ball valve, the downstream pipeline has been removable pressure, in order to disassemble, disassemble operationIt is important to be careful not to damage the sealing surfaces of the parts, especially non-metallic parts, to remove the O rings. Use special tools when taking apart and re assemblingWhen assembling, the bolts on the flange must be symmetrical and tightened gradually and evenlyThe cleaning agent should be compatible with rubber, plastic, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned by using gasoline (GB484-89). Non metallic parts are cleaned with pure water or alcoholThe non-metallic parts should be removed from the cleaning agent immediately after cleaning and should not be soaked for a long timeNeed to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution
Q:The difference between ball valve Q341F and Q347F
7: fixed ball valve, F: fluorine plastic valve seat sealStructural distinction:Floating ball: ball valve is floating, in the media under pressure, that the ball can produce a certain displacement, and tight at the outlet end of the sealing ring, to ensure that the export side seal, a single side forced seal.Fixed ball: the ball of the ball valve is fixed, the pressure does not produce movement, therefore, in the design, two sealing ring should be sufficient pre tightening force to ensure sealing, double sided forced seal.
Q:What's the difference between a ball valve and a butterfly valve? Which one has better sealing performance?
(1) the butterfly valve from the valve body, valve seat, valve plate, valve rod, all parts are a significant drain on the outside, one eye can see; the ball valve is composed of a valve body, the valve core (a round ball), valve rod, valve position is in the valve body inside, the naked eye can see only a part, so the seal the performance of the valve than the butterfly valve well;
Q:3/43/8 above the ball valve is not usually said of the big ball valve?
Ball valve above the 3/4, 3/8, refers to the ball valve connector, thread connection water pipe diameter, 3/4, 3/8 is the pipe diameter of the British size, 3/4 is 6 in charge, equivalent to 19.1 mm diameter; 3/8 is 3 in charge, 9.5 mm. Of course, the larger the ball valve, the greater the diameter.
Q:Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ
For example, the relationship between CF8M and F316.Natural gas pipelines look at bore, pressure, temperature, and composition.Clean natural gas with ordinary carbon steel ball valve on the line.Material basically A105N, LF2 based.As for pipes, I don't need to forge steel. My suggestion is that they should be made of forged steel.
Q:Would you please tell me why the spring is placed in the valve seat? What's the function?
The spring can also reduce the impact of the material on the valve.Ball 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:Butterfly valve, globe valve, ball valve used what is different
Butterfly valve, globe valve, ball valve used in different occasions:1. valve (Butterfly Butterfly) refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closure of a valve, the main cut off on the pipe 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. Butterfly valve is fully open to fully closed is usually less than 90 degrees, butterfly and butterfly stroke itself has no self-locking capability, in order to position the disc to install the valve stem on the worm gear. Using worm gear reducer, not only can the butterfly plate have self-locking ability, so that the butterfly board stops at any position, but also can improve the operation performance of the valve.Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.
Q:Heating live catch valve DN15 straight DN15 angle what does that mean?
As shown in the figure: straight DN15 is: straight through both ends, such as diameter of 15mm, angle DN15 is: bifurcated end nominal diameter 15mm.
Q:Is the two piece ball valve in the direction of the pressure pipe?
A piece of ball valve, the current market pressure of most products below 6.4MPA, two piece ball valve about 12.8MPA products are also common, there are 20MPA, three pieces of ball valves are mostly below 6.4MPA. Know the characteristics and shortcomings of these three kinds of ball valves, you can completely choose according to your own needs.
Q:In the wet alarm valve usually kept under working condition, alarm test ball valve state usually is closed or open?Because the alarm performance test on the pressure switch and hydraulic alarm, can be tested by open test ball valve, the bar working condition, the valve is closed or open? If so, if there is a police situation, if the police? If it does, it doesn't always call the police Seek expert advice.
Should be normally closed, the test valve is only the experimental pressure switch and hydraulic alarm, water from the valve directly into the alarm line, the wet alarm valve does not move, but you open, it usually has been ringing
