Q:What's the meaning of the ball valve bore 14 "x 12"?

The inner diameter of the two ends of the ball valve is 14 inches at one end and 12 inches at the other.

Q:What are the uses and characteristics of copper ball valves?

4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary

Q:What's the difference between angle valve and ball valve?

Generally, angle valves play four major roles:Switch out water outlet;When the water pressure is too large, it can be adjusted on the triangular valve, turn it down a little;With the function of switch, if the faucet leaks and so on, the triangle valve can be turned off in time, without closing the main valve in the house.The angle valve is generally a new house decoration essential water heating accessories, and play the role of a beautiful.

Q:What does W represent in copper ball valve Q11W-16T?

According to the provisions of the JB/T 308-2004 valve type programming method:Q== ball valve1== connection: internal thread1== ball valve structure: straight through flowW== sealing surface material: body. That is, the sealing material is the same as the body material-16== pressure rating: 1.6MPaT== body material: copper or copper alloy

Q:3/4 on the elbow of the water pipe. How about that ball valve?

3/4 inches converted approximately equal to 20mm, that is, DN20, can be equipped with DN20 caliber ball valve, commonly used for brass material

Q:What is the difference between ball valve Q41F-16C and Q41F-16P?

Two, ball valve Q41F-16PQ valve (Qiu represents the first letter of the alphabet), 4 representatives of 1 representative is flanged 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 16 of the nominal pressure valve is 16 kg (1.6Mpa). P represents the valve body material is 304 stainless steel.Ball valve Q41F-16P is a soft sealed stainless steel flanged ball valve

Q:What is an eccentric hemispherical valve? How do you understand?

The eccentric hemisphere valve and the flange gate valve belong to the same type of valve. The difference is that the closing piece is a sphere, and the ball rotates around the center of the valve body to open and close a valve.

Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What other commonly used valves?

Commonly used valves are: gate valve, globe valve, check valve, ball valve, butterfly valve, safety valve, regulating valve, plug valve and so onValve: valve is closed parts (RAM) vertical movement of the valve in the pipeline along the channel axis, used primarily as a medium cut that open and close use. In general, the valve can not be used as a regulation flow. The utility model can be applied to low temperature pressure, and can also be applied to high temperature and high pressure, and can be made according to different materials of the valve. But the valve is generally not used to transport mud and other media pipeline.Advantages: fluid resistance is small; the opening and closing torque needed by the smaller; can use the ring pipe flow to the two direction in the medium, that is to say the unrestricted flow of medium; the fully open, the sealing surface by the erosion of the working medium is smaller than the cut-off valve; the body has the advantages of simple structure, manufacturing good craft; the structure of relatively short length.Disadvantages: the size and height on the larger required installation space is larger; in the process of opening and closing, a relative friction sealing, friction is large, even scratch phenomenon caused by easily at high temperature; the valve has two sealing surface, to processing, polishing and maintenance of some increase the opening and closing time difficult.
