Detail:
Throttle device is a differential pressure type flowmeter, a sensor, and the differential pressure transmitter and display instrument (or computer) supporting the use, can achieve the measurement of fluid flow, and achieve the purpose of accumulation, display and control. Because of its has the advantages of simple structure, convenient installation, reliable use, wide application range: Standard throttle device to measure the suitable diameter 50mm - 1200mm, special throttling device diameter can also ranging from 12mm to 3000mm, temperature measurement can be up to about 550 DEG C; pressure up to 32Mpa and standard throttle device without separate calibration etc. characteristics is measure the flow process of the main instrument of industrial automation control.
Our company not only production throttling device of a conventional structure, but also the production of removable orifice plate throttling device, meet the scene flow changes in a wide range of degree of integration of throttling device, comprising an intelligent flow totalizer, differential pressure transmitter, the range of 1:10 ~ 1:40.
Product type and composition
The throttling device is composed of a throttling device (such as orifice plate, nozzle, etc.), pressure relief device (such as a ring chamber), a fastening device (Fa Lan, bolt, nut, washer, etc.), and other accessories (such as A), and can also be brought before and after the measurement tube (B) and straight pipe section Fa Lan (C).
1 throttle:
Is installed in the throttling device to make the flow of fluid in the section of the contraction, in the upper and lower reaches of the differential pressure of two components.
Standard throttle parts include:
The standard orifice plate, the pressure standard nozzle, the diameter of the pressure standard nozzle, the long diameter nozzle, the paper tube, the inner tube, the inner tube, the inner hole of the paper, the inner hole of the.
Non standard throttle parts include:
1/4 round hole plate (also known as 1/4 round nozzle), round hole plate, eccentric hole plate, double hole plate, cone type entrance orifice plate, small diameter hole plate, end head Kong Banhe limit flow orifice plate, etc..
2 pressure relief device:
On the circumference of the throttle, the different positions of the different position of the downstream side of a or a few pipe wall to take the pressure hole, which constitute a different pressure type is as follows:
(1) the pressure of the press: the end face of the pressure hole is close to the throttle piece, which comprises a ring chamber, a flange hole and a clamping ring.
(2) the pressure of the flange: the pressure hole is on the throttle part, the downstream side, the distance from the throttle, the downstream end of the 1 inch (25.4mm).
(3) D and D/2 (diameter distance) take the pressure: the pressure hole in the throttle, the downstream side, from the throttle, the downstream end of the 1D and 1/2D (D is the diameter of the pipe).
3 fastening device:
Device for clamping throttle. Such as flanges and bolts, nuts, gaskets, etc..
4 Annex: the guide, the root valve (stop valve), etc.
