Preferably, described wearing plate covers 2/3rds of described cylinder inboard wall girth in a circumferential direction at least.
Preferably, described wearing plate is corrosion resistant plate.Adopt corrosion resistant plate as wearing plate, increased wearability, further improved the service life of product.
Preferably, described liquid level emasuring device is the magnetic flap level gauge.The magnetic flap level gauge has the mangneto contraction structure, and it is more clear to show, more responsive to the minor variations of liquid level, so level gauging is more accurate.
Preferably, described pressure samples pipe is stainless steel tube.Adopt stainless steel tube to replace traditional carbon steel pipe as the pressure samples pipe, solution has been grown the serious problem of stopping up of later internal corrosion because of the pressure samples pipe service time, thereby has avoided the inaccurate defective of consequent pressure measxurement.Use stainless steel tube as the pressure samples pipe, pressure measxurement is more accurate.
Preferably, the large gas outlet of the inherent described row of described cylindrical shell also is provided with the exhaust screen device.Adopt the exhaust screen device, can prevent that steam from flinging out row's atmosphere outlet outside.
More preferably, described exhaust screen device comprises gas outlet cylindraceous, and the barrel of described gas outlet is provided with a plurality of through holes, and described gas outlet upper end communicates with described row's atmosphere outlet, and its lower end is coated with barrier plate.
More preferably, described a plurality of through hole is same apertures and evenly distributes.
More preferably, described barrier plate is and the concentric downward opening coniform plate that is connected of described gas outlet.
Preferably, described manhole is arranged at the bottom of described left end end socket.Manhole is arranged at the bottom of end socket, is convenient to maintenance and the maintenance of equipment.
Because adopt technique scheme, compared to prior art, a kind of regular unloading container level gauging provided by the invention and pressure measxurement are more accurate, longer service life, and be convenient to maintenance and maintenance.In further improvement of the present invention, the pressure samples pipe by adopting magnetic turnover plate type liquid level gauge and stainless steel tube to make makes level gauging and pressure measxurement more accurate; By manhole being arranged on the bottom of end socket, maintenance and the maintenance of equipment have been made things convenient for; By in the outlet of row's atmosphere the exhaust screen device being set, prevent that steam from flinging out row's atmosphere outlet outside.
