Q:I installed here in the water pump inlet, water pump with a 100 tons of water tank, there are many pumps, long time running, the pump will heat the cylinder, there is no water in the cylinder, the pressure does not go. The water pump is imported. Is the check valve broken or is the installation position wrong?: The function of the check valve is to prevent the backflow of water and cause the phenomenon of air embolism, so the check valve is the water inlet of the water pump, and the first time the check valve must be filled with water above the check valve. In order to check the following air and water slowly discharged. Your phenomenon may be the pump power is too small, pressure can not open the check valve.

Q:Which type of check valve should be selected for vertical pipes?: The check valve on the vertical pipeline shall ensure that the spool goes back to its position when the fluid is stationary and reversed.Optional:Butterfly check valves, pipes of low pressureVertical lift check valve, high pressure resistance, good tightnessSwing check valve: flow must be from the next up, the pipe diameter is unlimited

Q:What is the difference between globe and check valves?: 1. check valve is called one-way valve, the role is to prevent fluid flow, can not be adjusted, can not be closed.2., the cut-off valve can be used to regulate flow, can be closed, can be closed.

Q:What kind of valve does the check valve belong to?: 1. check valves are automatic valves;2., if the valve is cast iron, can be cast iron valves; if the valve is cast steel, can be cast steel valves; of course, can also beIn copper valves, stainless steel valves,,,,,,,3., if used in steam, can belong to the steam valve

Q:What does the swing check valve "h44h-16" mean?: H44h-16 is the type of swing check valve, respectively: H check valve, 4 flange, 4 swing type H alloy steel, sealing 16 kg pressure

Q:What does the number 16 on the check valve mean?: This is the pressure level of the valve, which represents 16Kg, which is used for piping pressure less than this pressure.

Q:What does the check valve "h61h-25 H" mean?: The first h or the latter H?According to the provisions of the JB/T 308-2004 valve type programming method:H = check valve6 = connection: Welding1 = structure form: lifting typeH = sealing surface material: Cr13 stainless steel

Q:My house is public flue, a total of six floor I live five floors, with the side suction hood, hood in the windy outside started as soon as the check valve pops ring from occupancy, have what way?: Do you think the situation in the wind ` a valve installed in the opposite direction of the flue you can, you should pay attention to when installing wind don't understand the whole, an anti air valve system, like on the wall in the general store has large lampblack machine.
