Ball valve, ball valve in the field of Marine engineering and ship should stop valve), the standard of GB/T21465-2008 "valve terms" is defined as: opening and closing (sphere) driven by the valve stem, and around the axis of rotation movement of the valve stem.Use can also be used on regulation and control of fluid, the "V" ball valve, hard seal the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, micro solid material such as medium.And ball valve in the pipeline is not only more connected to the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two.This valve shall generally be installed in the pipeline.Classification of ball valve, pneumatic ball valves, electric ball valves, manual ball valve.

Q:Heating live catch valve DN15 straight DN15 angle what does that mean?: It's DN15 positive three way live ball valve.

Q:Would you please tell me why the spring is placed in the valve seat? What's the function?: Valve seat on both sides should be added spring, the seal pushed to the valve core to seal up, so put the spring.

Q:Stainless steel ball valve Q11F-10P 16P each letter meaning?: Q ball valve, the first 1 representatives of second representatives of 1 screw connection, ball valve floating ball (ball valve floating ball and fixed ball, 7 ball, F fixed on behalf of) on behalf of PTFE- PTFE seal (PTFE PTFE), representing 10 of the nominal pressure valve is 10 kg (1Mpa), P represents the ball body material is 304 stainless steel.Shanghai blue forest control valve Co., Ltd.

Q:What's the diameter of the 4 point ball valve?: "4 point ball" in the "4 points" is based on the length of units per inch evolved;Divide 1 inches (25.4mm) 8, 4 points 4/8, or 1/2 inches, equal to 12.7mm.Therefore, "4 points ball valve" diameter is 12.7mm.

Q:How many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Big 50, pleaseHow many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Beg you greatly! Don't forget the detailed form!: No detailed conversion forms are required. How many inches is the representation of inches?.In English, 12 inches are 1 feet, 1 inches =8 cents.So: 1/2 "ball valve, =4 sub ball valve, 1/4" ball valve, =2 sub ball valve, 3/8 ball valve, =3 sub ball valve, and so on.Just a simple conversion relationship.

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:What's a twin hot melt ball valve?: Is a plastic ball valve, connecting France is hot melt.

Q:Must I use the ball valve for the heater?: Valve main points and angle valve, ball valve in the water pressure is large enough to use, angle valve can increase the pressure of a little water.

Q:What is the difference between ball valve and plug valve?: Plug valves are closed or plunger shaped rotary valve, through the rotation of 90 degrees to make the valve plug on the mouth of the channel with the valve on the mouth of the same or separated, to achieve a valve opening or closing. Plug valve plug shape can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the tapered valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve lighter, but at the same time a certain loss. Plug valves are most suitable for cutting and turning on the medium and for shunting applications, but in accordance with the applicable nature and sealing surface erosion resistance, sometimes also used for throttling. As the plug seal between the movement with a wipe action, while fully open, you can completely prevent the contact with the flow medium, it is usually also used for suspension with particles of media. Another important feature of the plug valve, it is easy to adapt to multi-channel structure, so that a valve can get two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valve used, and some connecting fittings needed in the equipment.Plug valves use:Plug valves are widely used in oil production, transportation and refining equipment, but also widely used in petroleum, chemical, chemical, gas, liquefied petroleum gas, HVAC and general industries.

Q:What do you mean by ball valves dn20pn1.6rf?: DN20 caliber is 20mmPN is the pressure grade, usually PN16, 1.6MPa classRF convex flange connectionYour side should be similar to the Q41F-16 model of this type of ball valve
