Type: type SKLGB series

Type: nozzle throttling device

Measuring range: 1932 nozzle: 50 ~ 500; The length to diameter nozzle: 50-630

Nominal size: DN50-DN1000

The accuracy of measurement: 1-2.5

Nominal pressure: 10 or less (Mpa)

Scope of application: gas and liquid

Features:

Nozzle flowmeter smaller pressure loss;

To save energy;

More strong and durable;

Suitable for high temperature and high pressure fluid;

Widely used in electric power, chemical and other industries of steam flow measurement;

Nozzle flowmeter include standard nozzle (ISA1932 nozzle) and two long neck nozzle. The design and manufacture are in accordance with international standard ISO5167 or the provisions of the national standard GB/T2624.

Standard nozzle plane perpendicular to the axis of the entrance by part A, circular arc form surface contraction section B and C of entrance, the edge of cylindrical throat E and to prevent damage to the protective tank F, pressure from its ways upstream pressure mouth Angle of using access, downstream take pressure can be set up by the pressure of Angle joint, also can be set up in the far downstream.

The total length of the nozzle

When 0.30 beta 2/3 or less or less, the nozzle length = 0.6041 d

When two-thirds beta 0.80 or less or less, the nozzle length = {0.4041 + (0.75 / beta 0.25 beta 2-0.5225) 0.5} d

SKLGB type series nozzle flowmeter throttle device upstream face by perpendicular to the axis plane and profile for the two arcs of a circular, cylindrical throat and groove for the identified contraction of the nozzle. SKLGB type series nozzle flowmeter throttle device way of selecting pressure Angle only pressure a pick up.

Length to diameter nozzle upstream face by perpendicular to the axis plane and profile for the quarter ellipse contraction, cylindrical throat and possible grooves or Angle of the nozzle. Length to diameter of nozzle take pressure way - D / 2 D only take one pressure.
