Q:What are the inside parts of the ball valve?
The universal ball valve includes the stem, valve ball, seat, seat seal and packing.
Q:What are the applicable conditions of ball valves?
Ball valve is also suitable for light structure, low pressure cut-off (small pressure), corrosive medium piping system. Ball valves can be used in cryogenic (cryogenic) units and piping systems. In the oxygen pipeline system of metallurgical industry, ball valve with strict degreasing treatment should be used. The main line in the oil pipeline and gas pipeline shall be buried in the ground, and all pass welding type ball valves shall be used. The ball valve with a V shape opening shall be used when required to adjust the performance. In the petroleum, petrochemical, chemical, electric power and urban construction, the piping system with working temperature above 200 degrees can choose metal to metal sealed ball valve.
Q:Is the ball valve the same as the float valve?
The answer upstairs is more accurate, I will add.1. ball valve: refers to the valve spool (seal components) for the ball shaped valve, collectively known as ball valves.2. float valve, that is upstairs to explain the kind of specific, you can refer to the toilet, which is used on the water supply device is this structure.The 3 threaded valve, threaded flange valve, valve flange welding flange or valve: This refers to the connection forms of body, such as your home with the water valve between the valve and pipeline is usually a threaded connection, then the other is threaded, welding, flange connection means.
Q:What is the service valve?
I'm talking about the ball valve, because I don't know exactly what you're talking about. I'll explain it to you literally. I don't know, right?
Q:Ball valve leakage of this place, how do?
The seal on the valve body is broken. Screw it down and change the gasket
Q:Copper ball Q11F-20T is what mean?
Q ball valve1 internal thread1 throughF PTFE soft seal20=20PA=2.0mpa pressureT copper material
Q:Are ordinary ball valves standard?
DN20, standard parts are produced according to the national standard size, you say ordinary ball valve, if it is according to the standard size is standard
Q:Is the drain valve the same as the ball valve?
Drain valve and ball valve function is not the same.The main function of the drain valve is to protect the safety of the pipeline. When the water pressure is too large, it will drain automatically and reduce the pressure of the pipeline. It is a valve installed in the pipeline system.
Q:How much pressure DN65 ball valve?
16-40 is normal pressure. How much pressure do you want?
Q:What does telescopic ball valve mean? What does it mean?
An expansion valve is mostly for repair or replacement of the water meter behind the expansion is the activity space, for example for water when the water meter is just let it back so easily won, for good and put it out to tighten the gentry good handle table.
