With the advancement of society, pipe transportation has been the principal ways for the material transportation on the planet, particularly for the long transportation for gas and oil. It is accounted for that an incredible number of oil creation nations or utilization nations utilize long pipeline to settle the transportation of various asset like oil or gas. 95% gas transportation takes on the pipeline way. As indicated by insights, as of now, the all out length for the pipeline utilized for moving oil and gas has been over 2.6 millions kilometers. Since the pipeline utilized for long transportation is extremely lengthy and furthermore will go through a ton of cruel places like desert, backwoods, stream, mountain, bog, etc, the necessity for long pipeline ball valve is high than the normal one to guarantee the wellbeing, sealability and strength.
In the long pipeline framework, the necessary pipeline ball valve should have the accompanying capabilities like controlling the medium, steering the medium stream, forestalling reflux, removing the medium, impeding the line, etc.
To understand the previously mentioned van bi điều khiển khí nén capabilities, the long pipeline ball valve should be furnished with the accompanying elements. First and foremost, dependable sealability. The significant distance pipeline must be checked at the standard time and once in a while it needs to go through high mountain, desert, meadow, tremor locale and different spots. On the off chance that the sealability isn’t great, it perhaps will bring about spillage or even the serious mishap. Thusly, for forestalling these things, this sort of valve should have the great sealability, particularly for the sealiability of dire oil infusion. Furthermore, the activity time ought to be long. When the long pipeline ball valve is utilized, it can not quit working in quite a while or even in over decade. The more it works, the better it is. For draw out the assistance time, the valve seat is vital.
Since somewhat it relies upon the utilizing season of the valve. Thirdly, the valve should have the high strength and obstruction force. In the transportation cycle, the strain of this valve might reach at 10.0MPa and the length might be extremely lengthy. Consequently, it is not difficult to experience the broadening, bending or just barely getting by the outside powers like quake, temperature or hardware vibration. To guarantee the ordinary activity of the valve, enough strength is fundamental. Fourthly, the long pipeline ball valve ought to be impervious to erosion. Since the flammable gas contains the Hydrogen sulfide, which can dissolve the valve and eat the mechanical gadget, it is critical to choose obstruction resistant material. Fifthly, it has the programmed capability. As we probably are aware, the long pipeline ball valve is constrained by the focal control room. So to control the valve at the significant distance right away, the valve ought to be controlled naturally. To wrap things up, the valve should be light in weight and tight in structure. With this element, it is helpful to introduce and fix the valve.
