Q:Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is so,Ball valve leakage of this place, how do? Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is the case, how can I ask?

It may be there when rust, so the Water Leakage, move it off slowly, rust, water Heicha out.

Q:Open the pressure relief valve core hole with what

Eccentric semi ball valve you say is a kind of ball valve, ball valve is a relatively new category, it has some advantages of own unique structure is divided into a type eccentric semi ball valve and side mounted eccentric semi ball valve in the maintenance of several, mainly according to the structure to pack type eccentric semi ball valve the structure is with a cover, can be in the pipeline maintenance, convenient and labor-saving, eccentric semi ball valve in the appearance structure for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and the cost, and side mounted valve has the advantages of compact structure, light weight, suitable for valve installation space requirements.

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:Is the ball valve installed in a direction?

Valve installation generally no direction required, any end of the valve can be mounted on the upper end. If the valve marked the direction, then it should be installed in the direction of tagging installed.

Q:Check valve, ball valve, check valve are used in what place, ah?

The cut-off valve is generally used in the inlet pipe, the outlet valve is generally used in the official website, convenient switch, check valve is to allow water to flow past the water directed, anti back, generally used in vertical pipe, valve equivalent pump: the following are the cut-off valve check valve valve identification pictures, please note.

Q:What are the types of vacuum ball valves?

Vacuum ball valve refers to the work pressure is lower than the standard atmospheric pressure, forming a certain vacuum ball valveVacuum ball valve models are GUD, GDQ, KF16, GU, KF and so onVacuum ball valve type has electric, manual, pneumatic, such as GU manual vacuum ball valve

Q:For the master enlighten Q47 ball seat spring hole number is determined by how

Force = spring stiffness (kg/mm) * compression volume (mm)Number of work cycles of spring stiffness = line diameter *1000/C 3 timesC= spring middle diameter / line diameterSpring diameter = spring outside diameter line diameter
