Q:What are the valves at home?

Valve used in the family is commonly used, the following are several:On the water pipe are: total table of the ball valve (32mm), in charge of the (25mm), as well as for the toilet, washbasin, water heater angle valve (20mm).Other commonly used gas pipelines, valves, pressure reducing valves and the like.

Q:The expert can tell me how to install this valve, and what fittings to use on both sides

On the first floor, the two floor adds up to the perfect answer: look at the flow direction and weld it directly to the pipeIf the process permits, you can first weld on both sides of the flange, modified into a flange butterfly valve, and then installed on the pipe, easy to overhaul later

Q:What do the Z, J, H and D represent in the valve type?

7, pairs of clipsThe transmission modes of valves are code 9, 6 and 3 respectively:9, electric, 6, pneumatic, 3, turbo wormBody material code Z, K, Q, T, C, P, R, V, respectively:Grey cast iron, malleable cast iron, ductile iron, copper and alloy, carbon steel, stainless steel, chrome nickel chromium nickel molybdenum stainless steel, chromium molybdenum vanadium steelSeat seal or lining code R, T, X, S, N, F, H, Y, J, M, W, respectively

Q:Ketem valve relative to other valve companies in the industry what are the advantages?

Floating seal: electric drive, electric ball valve flange connection floating ball straight, seal form with seal, the sealing surface of the valve seat material for hard alloy, nominal pressure PN16~PN63, nominal size DN15~DN200, suitable temperature of -28~500, the valve body is made of carbon steel or stainless steel. As a result of the use of hard sealing (metal seal), this valve is particularly suitable for particles, solids, slurry and other medium and high temperature and high pressure pipelines.

Q:the use of natural connections, is strictly prohibited counterparts. What do you mean by "strong opposition"?

Pro, strong counterpart refers to the valve in the pipeline connection, generally refers to the thread connection or welding to connect the valve, the valve and pipeline connection imposed by the larger external force, it will cause great stress and plastic deformation, easy to cause the valve to open or close the lax.

Q:What kind of valves are best used for sand drain valves?

Suzhou ATW Valve Co. Ltd production of sealing ball valve, Suzhou ATW Valve Co., according to the condition of solid particles, long-term research and in practice, and achieved good results in the condition of solid particles. You can try!

Q:What does the whole copper valve mean?

The whole valve is made of copper material. In addition to the ceramic core.

Q:What does LBC mean in a valve?

LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.

Q:How can the material be checked by valve approach? What experiments do you need?

May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.

Q:So how does the valve turn on?

The handle of the valve is opened along the pipe and perpendicular to the pipe
